API and systems integration for stacks that stopped talking to each other.
Custom REST and GraphQL APIs built in Missouri that connect your ERP, CRM, and payment stack — so data moves once, automatically, instead of by export, email, and copy-paste.
The most expensive software problem we see isn't a missing feature. It's two systems that both hold the truth and disagree — the CRM (your customer database) says one thing, the ERP (the system that runs orders, inventory, and finance) says another, and someone on your team spends Fridays reconciling them by hand. Integration is how you stop paying a salary to move data between tabs. We build the connections that keep your systems in sync on their own.
Where integration pays for itself.
One source of truth
Orders, customers, and inventory sync across systems in near real time, instead of an overnight export that's already wrong by 9 a.m.
Custom APIs, not brittle plugins
We build documented REST or GraphQL endpoints (the two standard ways for software to exchange exactly the data it needs) that your other tools can safely build on — not a marketplace plugin that breaks at the next update.
Payments and checkout, connected
Gateways, subscriptions, and tax or shipping providers wired into your store or app, with the edge cases handled rather than hoped over.
How we build an integration that holds.
Systems audit and data mapping
We document what each system holds, which one owns each field, and where the two disagree today.
API design and authentication
We design the endpoints and secure them properly — usually OAuth 2.0, the standard for granting access without handing over passwords.
Build and middleware
We write the connective layer that translates between systems that were never designed to talk.
Error handling and retries
Failures get caught, retried safely, and logged — because a sync that breaks silently is worse than no sync at all.
Monitoring and documentation
Alerting for when something goes wrong, and documentation so the fix doesn't depend on the one person who remembers how it works.
Senior execution, written in.
- Safe-to-retry syncs. Operations are idempotent (running one twice does the same thing as running it once), so a hiccup doesn't double every order.
- Webhook and queue architecture. Events are processed reliably under load, not fired and forgotten.
- Secrets managed properly. API keys and credentials are stored the right way, not pasted into a config file in the repo.
- Versioned and documented. When the API changes, existing consumers don't break — and your GitHub holds the code and the docs.
Being explicit about misfit.
If a no-code connector like Zapier or Make already does what you need, reliably, use it and keep your money. We're for the cases those tools can't reach: high volume, custom business logic, or a system that simply has no ready-made connector. We'll say so on the first call if that's you, before you've spent anything.
