Finding a high-risk payment gateway, and you sell medical devices. Migrate everything to a new Shopify store.
You have been looking at lists of payment gateways that work with Shopify. Stripe, Square, PayPal, Adyen — they all have checkboxes next to them saying 'high-risk' or 'supports adult' or 'accepts CBD'. Here is what those lists do not say. The gateway is the technical plumbing. It connects your checkout to a payment processor. Shopify supports dozens of them natively, and more through apps. But the gateway itself does not underwrite you. Behind every gateway sits a merchant account — a MID, a relationship with an acquiring bank or payment processor. That is where the actual application lives. That is where a human or an algorithm decides whether to accept your business type, your geography, your volume, your history. A gateway that 'supports high-risk' merchants does not mean it will approve you. It means it accepts applications from people in your category. The approval is separate, specific, and yours alone. Merchants commonly spend weeks comparing gateways and hours on the actual underwriting — and then get declined by the merchant account on day one.
Move all of it into a new store, from $247
One-time packages, no per-record metering, no quotes. The order form unlocks the moment you pay, counts are matched against your old store, and the entire migration then runs a second time — the second pass has to create nothing.
What you are looking at
- Gateway comparison lists showing 20 options, each marked 'high-risk friendly', with no mention of MID approval odds
- Shopify's app store showing third-party gateways as a simple install, with no warning about the separate merchant account application
- A message that a gateway 'accepts high-risk merchants', interpreted as approval, actually meaning only that they take applications
- Assumption that if Shopify integrates a gateway, it will approve a new high-risk merchant — not true
- Discovery three weeks into setup that the gateway's parent processor has declined the merchant account application
The merchant account decision is the actual deadline. You can prepare the technical setup while applications are pending, but nothing clears until underwriting says yes. Some processors publish estimated timelines; most do not. Time in underwriting is time your store makes no money.
Why it happened — specifically for medical devices
Stripe, which underwrites Shopify Payments, restricts prescription-only and regulated medical devices outright. The primary trigger is device class and registration status: a Class I wellness device is ordinary retail, but Class II or higher devices require regulatory clearance evidence. The secondary trigger is efficacy claims — any statement that your device diagnoses, treats or prevents a condition reads to a reviewer as an unproven medical claim, which moves you from restricted to prohibited. Japan additionally restricts health instruments specifically, regardless of class.
Rule out the easy fix first — then deal with the real one
There is no documented Shopify route for medical devices, and the honest reason is that Shopify Payments cannot take them at any class level without a separate underwriting conversation that Stripe controls entirely. What merchants try first is connecting through Shopify's high-risk gateway integrations and hoping the device classification does not come up — it always does. The real path is to find a high-risk acquirer willing to take your specific device class, which means proving your regulatory status upfront: FDA 510(k) clearance, CE marking, or a genuine wellness exemption. That conversation happens outside Shopify.
It only helps if all of these are true:
- Your device must have valid regulatory clearance or a documented exemption for your jurisdiction.
- You must remove any claim that your device diagnoses, treats, prevents or cures a condition.
- You need a high-risk merchant account before connecting any gateway; Shopify integration alone does not secure one.
- Your processing history must show no prior payment declines or chargebacks related to device claims.
- You cannot process if your device is restricted in Japan and you ship there.
If any one of them does not hold, you are where everyone else on this page is: you need a store built around a gateway that will actually accept you — and everything you have built has to move into it without losing the catalog, the customers, the order history or the rankings.
What this means for a business like yours
💎 High average order value, so fraud and disputes cost more per event
A single dispute or fraud event becomes a material loss at high average order value, so underwriters will price reserves and rate penalties accordingly. The merchant account application will demand evidence of your fraud detection, address verification, CVV checking, and order review process. Shopify's third-party gateway fee applies to every transaction, which is material when your average order is large. Most high-risk acquirers will hold a mandatory reserve—often 5–15 per cent of rolling volume or a fixed dollar amount—as protection against a spike in chargebacks or fraud disputes. Honesty about your chargeback history matters more than optimism. A gateway list shows who processes the category; it does not show who will approve you or what reserve they will demand.
⚖️ Legal status is genuinely contested or actively changing
When the legal status of your category is genuinely contested or actively changing, the merchant account underwriting shifts from chargeback risk to legislative risk. Underwriters will ask where the product is legal, whether federal law might change the calculation, and how quickly you could pivot if a jurisdiction moves against you. They will price this uncertainty into your rate and almost certainly into a mandatory reserve. Shopify's additional gateway fee stacks on top. A processor that lists your category today may have different pricing or different criteria six months from now if the legal landscape shifts. Expect the worst terms available: higher percentage, volume cap, reserve. Build relationships with more than one acquirer if you can, because a single processor failure leaves you with no backup.
📦 Thousands of SKUs, deep variant matrices, distributor feeds
A large catalog with thousands of SKUs and variant matrices means you cannot hand-rebuild if you move gateways. The merchant account underwriter will want evidence that your system can reliably avoid selling prohibited items into prohibited jurisdictions—which matters most for weapons or age-restricted goods, but also for any category with geography-specific restrictions. Shopify's CSV export cannot carry videos, theme, metafields, discounts, redirects or orders, so a hand-migration is impossible anyway. When you approach a new acquirer, they will ask how you manage compliance at scale across your entire product range. A gateway that accepts your category means nothing if you cannot prove your SKU-level restrictions actually work. Plan the full migration—data structure, theme, image quality, SEO redirects—before you commit to a new processor. Underwriters want to see that you have already solved the operational problem, not that you are learning as you go.
What you actually have to fix
Underwriters do not change their minds because you asked. They change them because the facts changed. For medical devices, these are the facts that move the decision:
Obtain and document your device's regulatory clearance
This is the highest-yield fix because without it you cannot move forward with any acquirer. If you are selling in the US, you need either an FDA 510(k) clearance letter for your specific device and intended use, or a genuine Class I wellness exemption backed by a legal opinion. If you sell internationally, you need CE marking or equivalent. Gather the actual clearance documents, not a screenshot or a claim — acquirers ask for originals and will verify them.
Remove every medical and efficacy claim from your store
Efficacy claims are the most common decline trigger. Audit your product descriptions, your FAQs, your email sequences and your ads for any statement that your device diagnoses, treats, prevents, cures or manages a condition. This includes indirect claims: 'supports joint health' or 'promotes better sleep' read as therapeutic. Switch to structure-and-function language only — what the device does mechanically, not what it does to the body.
Identify a high-risk acquirer before applying through any gateway
Do not assume that connecting a gateway on Shopify will unlock payment processing. High-risk acquirers for medical devices publicly advertise they take this category, but they run their own underwriting after you apply — they will ask for your clearance documents, your product claims, your processing history and your chargeback data. Start conversations with acquirers who explicitly mention medical devices. Have your regulatory documents ready before you reach out.
Prepare a clear business plan for your underwriting conversation
Acquirers want to understand your customer, your distribution and your claim-handling process. Write a one-page summary of who you sell to, how you acquired your customers so far, what your return and chargeback rates have been, and how you handle customer disputes or product returns. If you have been declined before, explain what changed. Honesty here outweighs a polished pitch.
What underwriting will ask you for
- FDA 510(k) clearance letter or CE certification for your specific device model and intended use
- Product labeling and instructions for use, showing no efficacy or medical claims
- A completed product classification worksheet mapping your device to its FDA class or equivalent regulator
- Supplier or manufacturing agreement proving you are authorised to sell this device
- Your privacy and data-handling policy, particularly if your device collects health information
- Recent bank statements showing transaction history and chargeback ratio
- A detailed business plan describing your target customer and distribution method
Getting underwritten for medical devices
High-risk acquiring is an entire industry that exists for businesses Stripe declines, and several of them publicly underwrite medical devices. What none of them will tell you up front is the number that actually matters: what your business gets offered, once they have seen your volume, your claims and your history. Rate, reserve and settlement terms vary enormously between applicants in the same category.

The recovery playbook
- Separate the gateway from the merchant account in your mindThe Shopify integration list shows what can be plugged in technically. The processor's application is what actually evaluates you. Installing a gateway in Shopify does not skip the merchant account step. It is the setup you can do in parallel. Write down the processor's name — the company that will actually underwrite you — separately from the gateway name. That distinction will save you weeks of confusion. When you get declined, you will know whether to blame the gateway (which is rare) or the underwriting criteria (which is the reason 99 times out of 100).
- Research the processor's actual criteria, not the gateway's marketingThe gateway's website will say 'we support high-risk merchants'. The processor's underwriting criteria — the thing that matters — lives in their application form, their policies, or a conversation with their underwriting team. Find it before you apply. Call them. Ask what business types they actually underwrite, what volume they need to see, whether they want reserves, what your rate will be. Cheaper gateways often cost more once you factor in reserves, higher rates, and transaction fees. Shopify also charges an additional third-party-gateway transaction fee on top of the processor's rate — tiered by your plan. That fee exists. Budget for it.
- Prepare your application materials while applications are pendingWhile the merchant account is being underwritten, you are waiting. Use that time to collect what processors will ask for: business registration, tax ID, processing history, bank statements, identity verification. Different processors have different checklists. Some will ask for personal guarantees. Some will want to know about past declined accounts. If you have been through a payment processor decline before, have that story ready and honest. Many processors now ask about MATCH history — the card networks' list of terminated merchants — and the answer matters more than the story. If you are on it, disclose it. Lying will disqualify you faster than the truth.
- Apply to multiple processors in parallel, not sequentiallyDo not pick one gateway, apply, get declined, then pick another. Research and apply to three to five processors whose criteria match your business type, in the same week if possible. Each application goes into the processor's system, and a decline does not flag you across all of them. But time between applications is time your store makes no money. Applications take days to weeks to process, so start the stack now rather than one at a time. Keep notes on each processor's criteria, rate, timeline, and reserve requirement so you can compare approved offers.
- Plan for worse terms than Shopify Payments, and budget the cost inIf you move to a third-party gateway, expect higher transaction rates, volume caps, rolling reserves, or setup fees. These are not bugs — they are how high-risk underwriting works. The processor is taking on more chargeback risk or regulatory scrutiny, so the pricing reflects that. Shopify Payments was a flat rate with no reserve. Your new processor will likely have both a rate and a reserve — money held back against chargebacks, sometimes 10 to 25 percent of monthly volume. That is working capital you do not have. Factor it into your business plan. If you cannot operate with a reserve, that processor is not a fit, and you move to the next application.
And then there is the part that actually loses businesses
If you do need a new store, the payments problem turns out to be the easy half. This is what is sitting in your current store right now, and what happens to each piece when someone tries to move it by hand:
Why this category in particular
Medical device data is dangerous to move by hand because regulatory compliance metadata lives in metafields: FDA clearance references, intended-use codes, contraindication warnings, and device-classification codes are all stored as custom fields that a CSV export cannot carry. If these fields are lost or point to the wrong product during migration, your store renders with incomplete or missing regulatory information — and a customer injured by an unmarked contraindication creates liability that no processor will touch. The compliance chain must survive the move intact.
| What you own | How much of it | What breaks doing it by hand | What we do instead |
|---|---|---|---|
| Product images | 3,600images≈ 15 hrsbulk re-upload, ~15 sec each | By handthe CSV carries image URLs and alt text, but they point at your OLD store's CDN — so the moment the old store goes, every image 404s. Re-upload and Shopify appends a dedupe suffix to the filename, which breaks every theme section and product description that referenced the original URL | Automatedevery file re-uploaded through the API with its alt text and variant attachment intact, its content type preserved so image-restricted fields still accept it, and every reference to the old URL rewritten |
| Product descriptions | 450descriptions≈ 2 hrsone pass to repair inline image links — the CSV carries the text | By handdescriptions are full of inline images and links pointing at the old store's CDN. Paste them into the new store and the text survives perfectly while every embedded image quietly dies — which you usually discover from a customer, not from a report | Automatedbodies copied verbatim, then a second pass rewrites every source-CDN URL inside them to the re-uploaded file on the new store |
| Product attributes & variants | 1,350variants≈ 45 minthe CSV carries these; the time is verifying option order | By handoption ORDER is part of the product's identity. Rebuild "Size, Colour" as "Colour, Size" and every theme swatch, saved customer URL and app that keys on variant position breaks — silently, because the product page still renders | Automatedvariants upserted by SKU with option names and order preserved, so swatches, deep links and app data keep working |
| Metafields & metaobjects | 6,300metafields≈ 42 hrsonly the reference, JSON and metaobject fields, ~1 min each | By handthe product CSV carries simple text and number metafields — but not metaobjects, and not reference or JSON types, which is exactly where app data and theme content live. Reference fields are the real trap: copy the value and it still points at objects in the OLD store, so the page renders and the custom block is silently empty | Automatedwritten in dependency order after their targets exist, with embedded references re-pointed at the new store's objects — and any value whose reference cannot be resolved is dropped rather than written broken |
| SEO data & redirects | 600records≈ 3 hrsredirects one at a time, plus a handle audit | By handany handle that changes becomes a dead URL with no redirect, and existing 301s are not in the product CSV at all. Years of accumulated ranking and backlinks end up pointing at pages that no longer resolve — the most expensive thing on this page to get wrong, and the slowest to notice | AutomatedSEO titles, meta descriptions and handles carried across, and every existing 301 recreated, so nothing that used to rank starts 404ing |
| Your custom theme | 1theme≈ 6 hrs2–10 hrs depending on how customised it is | By handa theme is not just its files. The settings, section content and block ordering are stored against the store, so a file copy gives you the layout and none of the content. Hardcoded asset URLs and tracking snippets also still point at the old store | Automatedyour live theme pulled and pushed as-is, then scanned for tracking snippets and hardcoded URLs that need re-pointing |
| Product videos | 25videos≈ 2 hrsre-upload and re-attach, ~4 min each | By handthe product CSV does not carry video or 3D media, so every one is a manual re-upload. They also cannot be pulled straight from a remote URL — the bytes have to be downloaded and staged first, and a wrong content type lands the file as a generic attachment that media-restricted fields then reject | Automatedvideo bytes downloaded, staged through a proper upload target, re-attached to the right product, and verified as processed rather than silently failed |
| Customers | 2,800customers≈ 2 hrsCSV import, then cleaning up the rows that fail | By handthe importer works, but marketing consent is the exposure: the CSV carries the current opt-in state and NOT the timestamp or source behind it. Re-opting someone in is a compliance breach, dropping them burns list revenue you paid for, and you cannot prove which happened afterwards. Default-address designation is also lost | Automatedcustomers upserted by email with every address, the default-address designation, and email and SMS consent states and timestamps preserved exactly as they were |
| Order history | 4,200orders≈ 8 hrsa paid third-party importer, plus a day of mapping and reconciliation | By handShopify's own CSV importer cannot create orders at all, so the hours here assume you buy a third-party importer — key them in by hand instead and 9,400 orders is closer to 390 hours, which is why nobody does that and why order history is simply abandoned in most DIY moves. Then support cannot answer a warranty claim, repeat-purchase segments are empty, and every returning-customer flow starts from zero. Getting the mapping wrong duplicates orders or re-dates them to today, and both are worse than not importing at all | Automatedfull order history recreated through the API with line items, properties, customers re-associated, original dates and tracking numbers intact |
| Navigation menus | 3menus≈ 1 hrsabout an hour to rebuild and relink them all by hand | By handmenu items store resource IDs, not paths, so nothing about them is portable — every link has to be re-pointed at the equivalent collection, page or product on the new store | Automatedmenus rebuilt with their nesting, and every item re-pointed at the equivalent object on the new store |
| Discount codes | 45discounts≈ 1 hrsabout 1 hr via the discount CSV, or ~3 hrs rebuilt by hand | By handthe discount CSV covers basic codes, but automatic discounts, quantity breaks and combination rules are not in it and have to be reconstructed by hand. A subtly wrong rule is worse than a missing one, because nobody notices until it has been over-discounting for a fortnight | Automateddiscounts recreated through the API with their rules, usage limits and dates intact, including automatic and free-shipping types |
| Blogs & pages | 30articles & pages≈ 2 hrsrecreated one at a time, ~4 min each | By handno CSV route for either. Articles also have no SEO fields of their own — their title and description tags live in metafields — so a hand-rebuilt blog loses its SEO even when every word of the text is right | Automatedarticles and pages recreated with authors, tags and publish dates, their SEO written to the metafields Shopify actually stores it in, and inline image URLs rewritten |
| Apps & app data | 12apps≈ 12 hrsabout 1 hr per app to reinstall, reconfigure and re-test | By handmost app data lives in metafields on your products and customers, so reinstalling the app gets you an empty app: reviews gone, subscription plans gone, loyalty balances gone, bundles gone. Flows and automations have to be rebuilt by hand and re-tested, and anything with its own billing has to be re-subscribed | Automatedthe metafield data your apps rely on migrates with the products and customers it hangs off, so a reinstalled app finds its data waiting instead of an empty store |

A new legal entity does not help you in this category. If you have been declined for medical device processing, a new company does not reset your underwriting risk — it simply restarts the same clearance and claims review. MATCH, the payment industry's decline database, follows the person behind the business for five years. A new entity structure without addressing your regulatory status or efficacy claims will result in the same decline.
Frequently asked
Which payment gateway will process medical devices?
The gateway is not the bottleneck — the merchant account is. Several acquirers publicly advertise high-risk medical device processing and integrate with gateways Shopify supports natively, but which one will take your application depends on your device class, your regulatory clearance, your product claims and your history. Authorize.net on a high-risk MID, PaymentCloud, Soar Payments and Easy Pay Direct are known to underwrite in this space, but approval is never guaranteed. Start by preparing your regulatory documents and removing efficacy claims, then approach acquirers directly with a clear application.
What reserve should I expect?
Medical device merchants commonly report reserves of 5–10% rolling, held for 90–180 days. The exact reserve depends on your device class, your clearance status, your transaction volume and the acquirer's risk appetite. Class II devices with solid regulatory documentation often see the lower end; higher-risk classifications or new merchants may see the upper end. Ask any acquirer for their reserve policy before you commit.
Will my product metafields survive a store migration?
Shopify's native CSV export cannot carry metafields at all — not your FDA clearance references, not your device-class codes, not your contraindication warnings. If you migrate by hand, those fields vanish and must be re-entered manually, which is labour-intensive and error-prone on a catalogue of hundreds of devices. A full API-backed migration preserves every metafield intact, which is why compliance-heavy categories like medical devices are the highest-risk candidates for manual moves.
Can I start selling if I do not have FDA clearance yet?
No. Stripe and high-risk acquirers will not process a device without regulatory clearance or a documented exemption for your jurisdiction. If you are still in the FDA review process or pursuing a 510(k), you cannot legally take payments until clearance is granted. Attempting to process before clearance invites processor decline, chargeback exposure and regulatory action. Wait for the clearance letter before building your Shopify store.
What is the difference between a payment gateway and a merchant account?
The gateway is the software bridge connecting your Shopify checkout to a payment processor — it handles the technical flow of card data. The merchant account is your commercial relationship with the processor, and it is where underwriting happens. You can have the gateway installed in Shopify and still not be approved for the merchant account. The gateway is necessary but not sufficient.
If Shopify integrates a third-party gateway, will it approve me?
No. Shopify's integration of a gateway means only that the technical connection is possible. The merchant account approval comes from the processor that owns the gateway, using their own underwriting criteria. Some of those processors are more liberal with high-risk categories than others, but none of them approve everyone. Integration and approval are separate decisions.
Will I have to pay Shopify a fee on top of the processor's rate?
Yes. Shopify charges an additional third-party-gateway transaction fee on top of what the processor charges. This fee is tiered by your plan. It is a real cost and should be factored into your rate comparison when you are deciding which processor to apply to. The processor's advertised rate is not your total rate.
Can I appeal if a processor declines my merchant account application?
You cannot appeal to force approval, but you can reapply later if your circumstances change meaningfully — higher volume, longer business history, reserves in place, or a shift in your business type toward lower-risk activity. Some merchants reapply after six months to a year. Most processors will consider a fresh application if your profile is different. Lying on the reapplication will disqualify you entirely.
If I get declined by one gateway processor, will other processors know about it?
Each processor screens applications against the card networks' MATCH file — the list of terminated merchants — but they do not automatically see declines from other processors. A decline itself is not instantly shared across the industry. However, multiple hard applications in a short time can raise flags for some processors, and if you are on MATCH, every processor will see it. Apply thoughtfully to a few good fits rather than scattering applications everywhere. If you have been declined before, disclose it in the new application.
