API & system integration

Your systems don't talk, so someone on your team copies data between them.

We design APIs and integrations between your applications, payment gateways, banks, and SaaS tools, with error logging and monitoring so nothing fails silently.

Sync with retries automatic
Errors alerted

Signs it's time

Every manual step between two systems is a point of failure, and it tends to fail at the worst moment.

Copy and paste as a process

Someone exports from one system and imports into another every day or every week.

Many tools, no reliable data

You have a CRM, a store, accounting, and operations, and each tells a different story.

Integrations that break on their own

A script or Zap someone built years ago stops working and nobody notices until data is missing.

You can't connect what you need

The vendor has no connector, or your in-house system has no API for others to connect to.

What we build

Integrations built to last, with the practices a critical system needs.

Your own APIs

REST APIs documented with OpenAPI so your system can talk to any other, today and in the future.

Payment integration

Stripe, Square, PayPal, Authorize.Net, and recurring billing, designed so card data is handled by the gateway through tokenization.

Banking integrations

Reconciliation, transactions, and payments connected to your internal systems.

SaaS and business tools

HubSpot, Salesforce, Shopify, QuickBooks, Google Workspace, Microsoft 365, and the APIs you rely on.

Webhooks and real-time sync

Real-time events instead of scheduled exports, with duplicate prevention.

Replacing fragile integrations

Scripts, macros, or automations that outgrew themselves, rebuilt with logging, retries, and alerts.

How we do it

Data flow first, code second.

  1. Step 1

    System map

    Which systems you have, what data lives in each, and which one is the source of truth for every piece of data.

  2. Step 2

    Integration design

    API contracts, events, error handling, and security defined before coding.

  3. Step 3

    Build and test

    Development with automated tests and each vendor's sandbox environment.

  4. Step 4

    Monitoring and support

    Logs, alerts, and a status dashboard so you know everything is still syncing.

Integrations that move real money and data

Banking integrations, recurring payments, accounting systems, and platforms with thousands of transactions. An integration isn't done when it works the first time; it's done when it keeps working the day a vendor changes something.

How we get started

The free audit identifies which integrations give you the best return. Focused integrations can often be quoted at a fixed price without paid discovery.

$0
Audit: 30 minutes + a written summary
$2,500 – $5,000
2-week technical discovery, credited to the project
Nothing gets built without scope, milestones, and a fixed price in writing. If discovery shows you don't need a custom build, we'll tell you.

Frequently asked questions

When is Zapier or n8n enough, and when do you need a custom integration?

For simple, low-volume flows an automation tool may be enough, and we implement those too. A custom integration pays off when there's volume, business rules, sensitive data, or a need for reliable monitoring.

Do you handle credit card data?

We design integrations so card data is processed by the payment gateway through tokenization and never passes through your servers, which reduces your PCI compliance scope.

What happens if a vendor changes its API?

Every integration has monitoring and error logging, so a change is detected immediately. Under a support retainer, the update is on us.

Do you provide documentation?

Yes. APIs are documented with OpenAPI, and every integration includes its data map and an operations guide.
