One call
You describe the awkward part. Engineers on the call, not just sales.
For custom integrations
Payments as unique as your business.
Bring us the awkward part. A system of record from 2009, a money flow no product page describes, a migration nobody wants to own. We're a small, flexible engineering team, and building it alongside yours is how we'd rather earn the business.

WHAT YOU GET
The integration is the product, so we work on it too.
Most processors hand you docs and a support queue. We would rather be in the thread with your engineers until the thing actually settles money correctly.
You get engineers, not a ticket queue. A shared channel with the people who wrote the API, working against your actual constraints — not a tier-one script forwarding your question to somebody who will answer it next week.
Whatever it has to talk to. An ERP, a general ledger, a billing system somebody left behind, a homegrown admin tool with no API at all. We will write the adapter rather than tell you the integration is out of scope.
Money flows shaped to your business. Multi-party splits, staged releases against milestones, per-invoice terms, deposits and balances, or card and ACH mixed inside one order — modelled the way your business already works.
Migrations, card vault included. We move your tokenized cards off your current processor under PCI, run both stacks in parallel while you watch the numbers agree, and cut over without asking a single customer to re-enter a card.
Custom work, published price. Custom does not mean a mystery quote. You start from the same rate card as everyone else — 2.6% + 25¢ down to interchange plus above $5M a month — and the tiers apply automatically.
Built so your agents can maintain it. Whatever we build ships with typed tools, an MCP server and agent-readable docs, so the integration stays legible to your team and to the coding agents working in your repo after we step back.
HOW IT GOES
Five steps, no discovery theatre.
A short, honest process. If it turns out we are not the right fit for what you need, you will hear that in step two rather than after a quarter of meetings.
A written plan
What we build, what you build, and what it costs.
Sandbox build
Real code against the open sandbox before any commitment.
Parallel run
Both stacks live, numbers compared, until you trust it.
Cut over and stay close
We stay in the channel after launch, because the first month of real volume is when the interesting questions turn up.
TELL US THE WEIRD PART
If it sounds too specific to be supported, say it anyway.
The requirements people apologise for on the first call are usually the reason they are still on a processor they dislike. Join the waitlist and tell us what yours is — we will tell you plainly whether we can build it and what it would take.
GOOD QUESTIONS
Custom, explained plainly.
What counts as a custom integration?+
Anything the standard SDK and API do not cover on their own: connecting to a legacy system of record, an unusual money flow such as staged releases or multi-party splits, a migration off another processor, or compliance requirements specific to your industry.
What does the custom work cost?+
Scoping and the integration work we do alongside your team is part of taking you on, not a separate invoice. If a project is large enough that it needs its own scope and budget, you will have that in writing before anything starts — never as a surprise afterwards.
Do we still get the published rates?+
Yes. Custom integration work does not change the rate card: published tiers up to $5M a month, interchange plus above it, and the same situational fees. Waitlist members keep their early-bird rate on top of that.
Can you migrate us off our current processor?+
Yes, including the tokenized cards. We move the vault under PCI, run both processors in parallel so you can confirm the numbers agree, and cut over without asking your customers to re-enter their card details.
How long does an integration take?+
A straightforward one is days, because most of it is the standard SDK. Work involving a legacy system or a card-vault migration is usually a few weeks, most of it spent on the parallel run rather than on writing code. You get the estimate in the written plan, before you commit.
Can we evaluate before committing?+
Yes. The sandbox is open with no signup gate, so your engineers can build against the real API — with the SDKs, API tools and MCP server — while the scoping conversation is still happening.
EARLY-BIRD RATE
Bring us the hard one.
Join the waitlist, tell us what your payments actually have to do, and lock in an early-bird rate below every published tier while we work out how to build it.
