Merchant Onboarding Software That Boards the MID You Already Have
Midcove's merchant onboarding software connects your existing NMI, Authorize.Net, Stripe, or PayPal merchant account to one CRM — no new application, no re-underwriting, no waiting in an approval queue. Most merchants connect a gateway and go live the same day.
Keep your processor. Change how you manage it.
Traditional merchant account onboarding bundles two very different things into one package: the software you use every day and the merchant account behind it. Want a better dashboard? Apply for a new MID, sit through underwriting, renegotiate your rates, and hope the risk team says yes.
Midcove separates the two. Your merchant ID (MID) stays exactly where it is — with the processor that already approved you — and only the tools around it change. Our payment gateway integrations talk directly to the account your provider already underwrote, whether that's an NMI merchant account or an Authorize.Net gateway.
- Connect an existing merchant account from NMI, Authorize.Net, Stripe, or PayPal in one guided flow.
- No re-underwriting — the approval and rates you already negotiated carry over untouched.
- Board your own MID — or several — and route transactions by brand, region, or risk level.
- Go live the same day, because there is no new merchant account waiting on approval.
What you'll need to board
- Gateway credentials — an API key or login access — for the MID you want to connect.
- The basic business details already on file with your processor. Nothing new to submit.
- A few minutes to walk through the guided connection flow — no paperwork, no documents.
How Our Merchant Onboarding Software Works
Three steps stand between your existing MID and live transactions — most merchants finish all of them in a single sitting.
Connect your gateway
Choose NMI, Authorize.Net, Stripe, or PayPal and enter the API credentials your gateway has already issued. The guided flow shows you exactly where to find them in each provider's dashboard.
Verify the connection
Midcove runs a test authorization against your MID to confirm credentials, permissions, and settings are wired correctly — before a single customer transaction touches the account.
Go live
Start processing immediately through the virtual terminal, the drop-in plugin, or the REST API. Same-day merchant setup is the norm here, not the exception, because there is no approval step.
Traditional Re-Underwriting vs. Midcove BYO-MID
Applying for a new merchant account and connecting an existing one are entirely different processes — here's what each actually asks of you.
| Stage | Traditional onboarding | Midcove BYO-MID |
|---|---|---|
| New application | Full application with bank statements, processing history, and owner details | None — your gateway already has your file |
| Underwriting review | Days to weeks of credit and risk assessment | No re-underwriting — your existing approval stands |
| Risk of decline | Application can be declined or approved with conditions | None — Midcove doesn't approve or decline MIDs |
| Rates & processor relationship | Reset and renegotiated with the new provider | Unchanged — you keep the pricing you already have |
| What you provide | Business documents, financials, personal guarantees | Gateway credentials (API key or login) |
| Time to first transaction | Whenever underwriting clears | Same day for most merchants |
| Adding another gateway | A brand-new application, every time | Board NMI, Authorize.Net, Stripe & PayPal in one CRM |
The pattern is simple: everything slow about merchant account onboarding lives in underwriting, and underwriting only happens because a new MID is being issued. Connect the MID you already have and the slow part disappears.
From One MID to a Whole Portfolio
Boarding isn't a one-time event. Growing merchants add gateways, and ISOs board entire books of business — the same flow handles both.
Multi-gateway merchants
Run Stripe for online checkout and NMI for phone orders — or any mix of the four gateways — and route every transaction from a single login.

Fraud prevention toolsMerchant Onboarding Questions, Answered
Do I need a new merchant account to use Midcove?
No. Midcove connects to a merchant account you already hold with NMI, Authorize.Net, Stripe, or PayPal. You keep your existing MID, rates, and processor relationship — the only thing that changes is where you manage it.
How long does merchant onboarding take with Midcove?
Most merchants connect a gateway, verify the connection, and start processing the same day. Because there is no new underwriting, there is no application queue to wait in.
What does "no re-underwriting" actually mean?
Your gateway or acquirer already underwrote your business when it issued your MID. Midcove is software that sits on top of that approval, so connecting your account triggers no new credit checks, risk reviews, or document requests.
What information do I need to connect my existing merchant account?
Your gateway credentials — an API key or login access — for NMI, Authorize.Net, Stripe, or PayPal. The guided flow shows you exactly where to find them in each gateway's dashboard.
Which gateways does Midcove's onboarding flow support?
Exactly four: NMI, Authorize.Net, Stripe, and PayPal. You can board any one of them on Starter, or mix them across MIDs on Growth and Enterprise plans.
Will connecting my MID to Midcove change my processing rates?
No. Midcove is not a processor and never touches your pricing agreement. The rates you negotiated with your gateway or acquirer stay exactly as they are.
Can I board more than one MID?
Yes. Starter covers a single MID, Growth supports up to five across gateways, and Enterprise supports unlimited MIDs — useful for multi-brand merchants and ISOs managing a portfolio.
What happens if my gateway credentials fail verification?
The flow flags the failed test authorization and points you to the likely cause — usually a mistyped key or a missing permission. Fix the credential and re-run the check; nothing goes live until verification passes.
Is my gateway credential data secure during onboarding?
Yes. Midcove is built to align with PCI DSS requirements — credentials and card data are encrypted in transit and at rest, tokenized, and gated behind role-based access controls.
How much does it cost to board my MID with Midcove?
Plans start at $49/month for a single boarded MID on Starter. Growth is $149/month for up to five MIDs, and Enterprise pricing is custom. There is no setup fee on Starter or Growth.
