Make your systems actually talk to each other
Your CRM, payment gateway, ERP, and internal tools were built by different companies at different times. We connect them so data moves automatically instead of through manual exports and copy-paste.
Built for teams at these stages.
Businesses running on disconnected SaaS tools
Your CRM, accounting software, and support desk all hold different pieces of the same customer data, and nothing syncs between them.
Companies whose internal systems need an API that doesn't exist yet
An internal tool or database needs to expose data to a partner, mobile app, or another internal system, but there's no interface built for it.
Teams doing manual data entry between platforms
Someone is manually re-entering the same order, customer, or inventory data into two or three different systems every day.
What's inside this service.
- Custom REST or GraphQL APIs for systems that don't have one
- Integrations between existing platforms (CRMs, ERPs, payment gateways, support tools)
- Webhook handlers that react to events in real time
- Scheduled and event-driven data sync jobs between systems
- Authentication layers (API keys, OAuth) for secure system-to-system access
- Error handling and retry logic so failed syncs don't silently lose data
- Monitoring and alerting for integration health
Technical depth across the stack.

How an engagement runs.
Map the systems
We identify every system involved, what data each one owns, and where the current gaps and manual steps are.
Design the integration
We define how data will flow, which system is the source of truth, and how conflicts or failures get handled.
Build
We build the APIs, webhooks, and sync logic needed, testing against the real third-party systems as we go.
Test under real conditions
We test edge cases like duplicate events, rate limits, and partial failures, not just the happy path.
Deploy and monitor
We ship the integration with monitoring in place so you know immediately if a sync starts failing.
Tools and platforms we work with.
Where this service applies.
CRM and accounting system never stayed in sync
A services company was manually re-entering invoices between their CRM and accounting software every week. We built a real-time sync that removed the manual step entirely.
No API existed for an internal inventory system
A distributor needed their warehouse system to expose stock data to a new partner platform. We built a custom API with authentication and rate limiting from scratch.
Payment gateway needed to trigger fulfillment automatically
An e-commerce business processed orders manually after each payment. We connected the payment gateway to their fulfillment system via webhooks, removing the manual handoff.
