API Development & System Integration
Custom APIs and integrations that connect your CRM, ERP, accounting, scheduling and line-of-business systems, so data is entered once, moves on its own and stays consistent everywhere it lives.
Overview
If someone retypes data from one system into another, that is an integration waiting to be built.
Most organizations run a dozen systems that were never designed to talk to each other: a CRM, an accounting package, a scheduling tool, an ERP, a portal a vendor built years ago. People fill the gaps by hand, exporting spreadsheets, retyping orders and reconciling records at month end, and every manual step is a place for an error to start.
We build the connections properly. Where a system has a usable API we use it; where it offers only file exports, a database or a web screen, we build around that and tell you what it will cost to keep running. Every integration has logging, retries and alerts, so a failed sync is noticed by us rather than discovered by your finance team, and the code and documentation live in your accounts so you are never locked to us.
Capabilities
What's included
- Custom API developmentREST and GraphQL APIs that expose your data and processes to partners, portals and mobile apps, with authentication, rate limits and versioning.
- System-to-system integrationCRM, ERP, accounting, e-commerce, scheduling and HR systems kept in step, in real time or on a schedule.
- Legacy and API-less systemsIntegration through file drops, a reporting database or controlled screen automation when the old system offers nothing better.
- Webhooks and event processingEvents from payment processors, forms and SaaS tools received, validated, queued and processed without losing one under load.
- Data mapping and transformationField mappings, code translations and duplicate handling agreed in writing, so both systems agree on what a customer or an order is.
- Monitoring and error handlingEvery run logged, temporary failures retried automatically, and the rest alerted to a person with the affected records listed.
How We Work
Our approach
- 01
Map
Systems, data owners, volumes and the manual steps being replaced, with field-level mappings.
- 02
Design
Integration pattern, error handling, security and the build-versus-buy call on middleware, in writing.
- 03
Build & test
Built against sandboxes, tested with real volumes and edge cases, reviewed by your system owners.
- 04
Run
Deployed with monitoring and alerting, documented, and supported under a maintenance plan if you want one.
Outcomes
What teams see
Each run recorded, so any record's history can be traced.
In your repository and your accounts from week one.
Scoped and priced before any build commitment.
Common Questions
Questions we get asked
Should we use a tool like Zapier or build a custom integration?
Use the off-the-shelf connector when it handles your volume and your edge cases; it is cheaper to start and someone else maintains it. Custom integration earns its cost when the volume is high, the logic is specific to your business, the data is sensitive, or no connector supports the systems involved. We assess both honestly in discovery and will recommend the connector when it is the right answer.
Can you integrate a system that has no API?
Usually. Older systems nearly always offer something: scheduled exports, a reporting database, an import folder or an email feed. Where nothing else exists, controlled screen automation can drive the user interface, though it is more fragile and we will say so. Part of discovery is finding the most reliable route into the system and estimating what it will cost to keep that route running.
What happens when an integration fails?
It tells someone. Every integration we build logs each run, retries temporary failures automatically and raises an alert when a failure needs a person, with enough detail to see which records were affected. Records are not silently dropped; they wait in a queue until the problem is fixed and are then processed in order. You can see the history of any record that passed through.
Who owns the integration code?
You do. The code lives in a repository in your account from the first week, runs in your cloud or hosting account, and is documented well enough that another developer could take it over. Credentials for the connected systems stay in your control. Many clients keep us on a maintenance plan afterwards, but that is a choice, not a dependency.
