Systems integration
Most companies do not need another tool. They need the tools they already pay for to stop disagreeing, and to stop relying on someone re-typing the same figures every morning.
What this looks like in practice
Work we have actually done, described as work rather than as capability.
- Making two systems agree on one number
- Stock, balance, headcount — whichever number two systems each believe they own. Agreeing which one is right is the hard half.
- Removing manual re-entry
- Someone exports from one tool and types into another every morning. That person is the integration, and they are also the single point of failure.
- An API for something that never had one
- Older systems that expose a database, a file drop or a screen. We build the boundary they lack, rather than pretending they have one.
- Reconciliation with a visible failure mode
- Scheduled jobs that report what did not sync and why, instead of silently drifting until someone notices at quarter end.
Constraints we work with
The limits that shape this kind of project. Naming them costs us nothing and tells you more than a list of technologies would.
- Vendor APIs change without notice
- A field turns optional, a limit tightens, a response shape shifts. Integrations that assume stability break quietly, so ours check and complain loudly.
- Some systems nobody may modify
- Support contracts and certifications make the other side read-only. Then the integration lives entirely on our side, with all the awkwardness that implies.
- There is no test environment on the other side
- Often the vendor offers production or nothing. That changes how we work — smaller steps, reversible writes, and a rehearsal against copies first.
- The same word means different things in each system
- One tool counts an order at checkout, the other at dispatch. Most integration bugs are this, not networking.
Where this shows up in our work
Two systems that disagree?
Tell us which number they disagree about and who currently fixes it by hand. That usually reveals whether the answer is an integration or a decision about ownership.
