Your money. Your processor. Your terms.
We don't lock you into one payment processor. Stripe, Square, Venmo, Zelle, or your bank's merchant services — we integrate with what fits. We never take a cut of your sales.
The problem
Locked into a processor you didn't pick.
Most SaaS commerce platforms make the processor part of the deal. Toast bundles its own processing. Shopify charges a surcharge if you don't use Shop Pay. Square ties its hardware to its rates. The choice gets made for you, and you can't switch without rebuilding everything.
The rates you're paying might not even be the best for your business — but you can't shop around when your checkout, customer data, and inventory are entangled with one processor.
Stagg builds processor-agnostic. Your checkout abstracts over the processor. If a better rate comes along next year, you swap — same checkout, new backend.

What we use todayStripe
Card processing. Full API.
Default for online card payments, subscriptions, and SaaS checkouts. Wide feature set, predictable behavior, mature documentation.
Square
In-person + online.
If you have a physical location and need a terminal, Square's hardware plus its API plays nicely with custom checkouts.
Venmo
Zero processing fees.
For service businesses where customers are happy to pay via Venmo, every transaction is fee-free. Adds up over a year.
Zelle
Bank-to-bank, no fees.
For invoiced work and B2B payments. Funds settle into your bank account directly — no processor middleman.
Your bank's merchant services
Whatever you already negotiated.
If your bank already set you up on merchant services, we can integrate. Sometimes the best rate is the one you already have.
Whatever else has an API
Tell us who you want to use.
If your processor has a documented API, we can wire it in. Bring us the one you've already gotten the best quote from.
What actually changes.
The modelOne option, locked
- One processor · locked in
- Their published rates only
- No multi-processor routing
- A surcharge per transaction · forever
Pick + swap any time
- Pick + swap any time · no rebuild
- Your negotiated rates · we're not in the loop
- Route by channel or transaction type
- $0 platform cut from us · ever
PCI scope stays small either way — checkout is tokenized via the processor's iframe, so card data never touches our servers. The difference is who holds the keys. Full pricing breakdown →
No platform cut
We're not in
your transactions.
Whatever you pay, you pay your processor — never us. We build the checkout once, abstract the processor behind it, and step out of the money flow entirely. The fixed-price build and the optional flat $150/mo hosting are the only numbers we touch.
