API Development & System Integration

Price range: £8,500.00 through £17,000.00

Well-documented APIs and dependable integrations connecting ERP, CRM, payment and third-party platforms, delivered in three to six weeks.

Description

Enterprise environments accumulate systems that record the same customer under multiple identifiers. The cost does not appear on a balance sheet; it appears in manual reconciliation, duplicated data entry and reporting that the business cannot fully rely upon.

We design the API surface deliberately, selecting REST or GraphQL according to the consuming systems, then implement it with authentication and rate limiting appropriate to production load. Failure paths are tested rather than assumed, and documentation is produced for the team that will maintain the integration after handover.

Typical delivery is three to six weeks with two engineers on a fixed price determined by company size. It is a small, schedulable engagement and frequently the most cost-effective means of eliminating recurring manual work.
