Integration work is defined by the seams between other people's systems, and those seams are where documents matter most. Two vendors, each confident their product works correctly, connected by an interface neither of them owns — and when the data arrives malformed at month end, the argument is settled by whatever was written down about the interface contract. Integrators who document those boundaries precisely spend their time delivering; integrators who do not spend it in meetings establishing whose fault something is.

We edit what systems integrators produce — solution design and high-level architecture documents, interface specifications and integration design documents, data mapping and transformation specifications, migration and cutover plans, test strategies and test scripts, environment and deployment documentation, statements of work and change requests, RAID logs and project status reports, workshop outputs and requirement traceability matrices, handover and operational readiness documentation, training material for the receiving support team, and post-implementation review reports. Our editors check that responsibility boundaries are stated explicitly at every interface, and that the same field or entity is named identically across the mapping, the specification and the test script.

The interface specification is the document that determines whether an integration project stays on schedule, and the common failure is that it describes the happy path in detail and everything else not at all. What arrives at the seam eventually is a record with a null in a mandatory field, a duplicate delivered after a retry, a message that turns up out of order, or a batch that fails halfway. We write these specifications so each interface states its trigger and frequency, the exact field-level contract including formats and mandatory status, the behaviour on duplicate and out-of-order delivery, what happens to a record that fails validation and who is responsible for reprocessing it, and where the alert goes when the interface stops entirely. That last point is the one most often omitted, and an interface that fails silently is the defect nobody finds until reconciliation.

Everything you send is handled in confidence, including client architecture, commercial terms and project documentation under agreement. Whether you are an integrator standardising documentation across delivery teams, a client trying to understand what has been proposed, or a project preparing operational handover, we can make the documents precise about the boundaries that matter.
