API & Integration Work
Make the systems you already pay for finally talk to each other.
$2,500 – $10,000 typical range · Single-direction, two-system integrations typically ship in under a week. Multi-system or bidirectional work: 1–3 weeks.
Who it's for
Businesses re-typing the same data into two or three systems — the accounting package, the CRM, the e-commerce platform, the warehouse — because none of them connect.
The problem
Every re-keyed invoice is an error waiting to happen and an hour nobody gets back. Vendors sell "integrations" that cover the easy 80% and abandon you at your actual use case. The connecting code is usually small; the cost of not having it is not.
What you actually get
- A working integration: data flowing automatically between the systems you name, on the schedule or trigger you need
- Error handling and alerting — when a sync fails, you find out from the software, not from an angry customer
- The complete source code in a repository you own
- Automated tests against recorded real-world payloads
- Runbook: what it does, how to monitor it, what to do when a vendor changes their API
The process
- 1.
Scoping call
We identify the exact systems, the exact data, the direction of flow, and the failure modes. Quoted range in a written statement of work.
- 2.
Build
The agent team builds against the statement of work with reviewed, tested changes throughout.
- 3.
Parallel run
The integration runs alongside your manual process until you trust it. We compare outputs.
- 4.
Handoff
Repository, credentials rotation, monitoring, and runbook handed over.
The build is done by Favur, our autonomous multi-agent software team, directed and reviewed by us. Read exactly how that works.
Timeline

Quoted up front, settled at delivery from the compute the build actually consumed. Driven by the number of systems, whether data flows one way or both, and how well-documented the vendor APIs are. Poorly documented vendor APIs are our problem to figure out, but they honestly cost more.

Explicitly out of scope
- Becoming your outsourced IT department — this is a build-and-hand-off engagement
- Integrations that violate a vendor’s terms of service (scraping behind a login where the vendor forbids it)
- Real-time trading or safety-critical systems
What we need from you
- Admin or API access to the systems being connected (or the person who has it)
- A handful of real example records — the weird ones especially
- A decision-maker for the inevitable "when the two systems disagree, which one wins?" questions
Common questions
- Our vendor already offers an integration. Why pay for a custom one?
- If the vendor integration does what you need, use it — genuinely. Custom integration work is for the cases where it does not: the field they do not sync, the business rule they do not model, the second system they do not support.
- What happens when the vendor changes their API?
- The runbook documents exactly where the vendor-facing code lives, and the test suite fails loudly against a changed API rather than corrupting data silently. Updating for a vendor change is usually a small, quotable fix — by us or by anyone you hire.
- Is our data safe during the build?
- We build and test against sandbox accounts and recorded sample payloads wherever the vendor offers them, and we ask for the minimum access that makes the work possible. Credentials are rotated at handoff.
