Third-party Integrations (Payment, Shipping, CRM)

Overview

What we deliver

We integrate your product with payment gateways, shipping carriers, CRMs, and other third-party services with clean error handling and clear logs.

We help product teams connect their applications to the third-party services their customers and operations depend on. Our engineers build integrations with payment processors like Stripe and Adyen, shipping carriers including FedEx, UPS, and DHL, and CRMs such as Salesforce and HubSpot. We also handle ERPs, marketing platforms, and identity providers. We start by mapping the data flow, identifying failure modes, and confirming compliance requirements. Then we implement the integration with retry logic, webhook handling, idempotency keys, and audit logging so transactions stay accurate. We add monitoring and alerts for vendor outages, schema changes, and rate limit issues. Documentation covers field mappings, environment setup, and runbooks for support teams. The result is a connected system that handles real-world edge cases without manual intervention and stays maintainable as vendors release new versions.

Client stories

What clients say

"

My books were 90 days behind and I was avoiding my accountant. They cleaned up nine months of mis-categorized Shopify and Stripe entries, set up proper rules in QuickBooks, and now my close lands on day four of every month. First time in three years I opened a P&L without wincing. Cash forecasting actually makes sense now.

Holiday season was about to break us. We needed 22 agents in six weeks and our internal hiring pipeline could not move that fast. They staffed it, trained on our tone guide, and ran nesting alongside our senior reps. CSAT actually went up by three points during peak. First Q4 in four years my support lead took her vacation.
