APIs and integrations that make your tools talk.

It depends on how many systems you are connecting and how well-documented and cooperative their APIs actually are, but you get a fixed price in writing after a short discovery call, so scope is agreed before any billing starts. A single, well-documented integration between two modern systems costs meaningfully less than connecting five legacy systems with sparse documentation and inconsistent data formats, and we will tell you honestly which situation you are in once we have looked at the systems involved. For a rough ballpark first, try our free cost calculator, which accounts for integration complexity and returns an instant estimate. As a general shape, a straightforward integration between two well-documented modern APIs typically takes two to four weeks and lands in the low thousands; connecting several legacy or poorly documented systems takes longer and costs more, which the discovery call will clarify precisely.

CRMs, ERPs, payment gateways, logistics and shipping carriers, and analytics tools are the most common, though we have connected everything from inventory management systems to custom internal databases that predate any modern API standard. We design clear, well-documented APIs and integration layers so your systems finally agree with each other automatically, rather than someone on your team manually exporting a spreadsheet from one tool and importing it into another every week. This kind of manual bridging is more common than people expect, and it is usually invisible until the person doing it goes on leave or leaves the company, at which point the gap becomes obvious and urgent. We handle both directions: pulling data out of legacy or hard-to-reach systems, and pushing data cleanly into modern platforms your team already uses daily. If a system genuinely has no usable API, we say so plainly.

We build in retries, clear error handling and active monitoring specifically because third-party services do go down, sometimes for minutes and occasionally for hours, and an integration that silently fails during that window is far worse than one that visibly alerts someone. When a dependency becomes unavailable, failed requests are queued and automatically retried once it recovers rather than being lost outright, and if a failure persists beyond a reasonable window, an alert reaches a real person instead of the problem going unnoticed until a customer complains or data quietly drifts out of sync. We also build in sensible fallback behaviour where it makes sense, for example queuing an order for later processing rather than failing the whole checkout because a shipping API timed out for thirty seconds. A partner outage becomes a manageable, visible event your team can respond to, not a silent failure that only surfaces days later.

Yes. We design REST or GraphQL APIs with proper authentication, rate limiting to prevent abuse, and clear documentation your partners can actually work from without needing to email you constantly with questions about how an endpoint behaves. Good API design means thinking through versioning from day one, so you can improve the API later without breaking every partner integration built against the current version, along with sensible, consistent error messages that tell a developer exactly what went wrong rather than a generic failure. We typically provide interactive documentation, often built on the OpenAPI standard, so partners can test endpoints directly in their browser before writing any integration code themselves. Depending on your needs, we also set up sandbox environments and API keys with usage tracking, so you can see which partners are actively using the API.

Always, and this is not an afterthought we add if there is time left in the budget. You get clear API contracts describing exactly what each endpoint expects and returns, architecture diagrams showing how the systems connect and where data flows, and setup notes covering authentication, environment variables and anything specific to your infrastructure that the next person working on this will need to know. This means the next developer, whether that is someone on your own team, a future hire, or another agency entirely, can understand and extend the work without needing to reverse-engineer our decisions from the code alone or track us down with questions months later. We have inherited enough undocumented integrations from other teams to know firsthand how much time poor documentation wastes, and we would rather spend an extra afternoon writing things down clearly than leave you dependent on us indefinitely.
