Systems integration and API development
Making the systems you already own exchange data reliably, on schedule, without anyone re-typing it.
Most businesses do not need new software. They need the software they already pay for to talk to itself. Orders re-keyed into accounting, stock counted in two places, a monthly report assembled by hand from four exports.
This is the work we do most, and the work with the clearest return: the hours it removes are measurable in the first month, and the errors it prevents are the expensive kind.
What we build
API development
REST and GraphQL APIs built to be consumed — versioned, documented, authenticated, and predictable under error conditions.
ERP, CRM and accounting integration
Connecting systems including Zoho, QuickBooks, Xero, SAP Business One, Dynamics 365 and Odoo to the platforms around them.
Data migration
Moving data between systems with reconciliation, so you can prove nothing was lost rather than hoping.
Middleware and event pipelines
Queues, webhooks and scheduled synchronisation with retry logic and dead-letter handling, because integrations fail and silent failure is the dangerous kind.
What you get
- Field-level mapping document agreed before build
- Validation rules that reject bad data instead of propagating it
- Retry, alerting and dead-letter handling for every automated flow
- Reconciliation report proving the two systems agree
- Monitoring so you learn about a failure before your customers do
Questions about integration & apis
Our two systems have no official integration. Is that a problem?
Usually not. If both expose an API we can connect them. Where one does not, there are normally routes via scheduled file exchange, database access or a supported export format. We establish feasibility during discovery before you commit to a build.
How do you handle integrations breaking?
By assuming they will. Every flow gets retry logic, failure alerting and a dead-letter queue so nothing disappears silently. Most integration disasters are not the failure itself but nobody noticing for three weeks.
Can you integrate with government or regulatory systems?
Yes. We work on compliance-driven integrations including structured e-invoicing and regulatory reporting, which have stricter format and audit requirements than commercial APIs.
How long does a typical integration take?
Two systems with good APIs and a clear field mapping: one to three weeks. Add complexity for poor documentation, historical data migration, or business rules nobody has written down — which is the usual reason integrations take longer than expected.
