Systems integration that ends double data entry
ERP, CRM, e-commerce, payments and in-house systems talking to each other
— consistent data, handled errors and nobody copying information by hand.
The invisible cost of systems that do not talk
Almost every company has someone who spends part of the day copying information from one system into another. That work appears in no report, yet it costs hours a week, creates divergence between databases and produces the worst kind of error: the one nobody notices until a customer complains.
Integration fixes this by letting systems exchange data on their own. But good integration is not just "connecting" — it is deciding who owns each piece of information, what happens when one side is down, and how an error reaches a human when it needs a decision.
That part, what happens when things go wrong, is what separates an integration that runs for years from one that breaks silently and is only discovered at month-end close.
Who this is for
The most common scenarios.
Typing into two systems
The same information is entered twice because the tools do not talk to each other.
E-commerce and back office
Online store, stock, ERP and carriers that need orders, prices and tracking kept in sync.
Companies with legacy systems
An old system that works well, that nobody wants to replace, but that has to talk to the new stack.
Payments and billing
Gateways, invoices, instant payments, subscriptions and reconciliation that today depend on a spreadsheet and manual checking.
What we deliver
Integration that keeps working when something goes wrong.
Custom APIs
Development of your own REST APIs — documented, versioned and authenticated — for your partners or your systems.
Synchronisation between systems
Defining which system is the source of truth for each field, and syncing both ways when required.
Third-party API consumption
Connections to ERPs, CRMs, gateways, carriers, tax systems and any service that offers integration.
Failure handling
Automatic retries, a reprocessing queue and alerts to a human when the failure needs a decision. Nothing disappears silently.
Security
OAuth 2.0, rotated keys, encrypted traffic and a log of every call for auditing.
Monitoring
A dashboard with volume, latency and errors per integration. You find the problem before your customer does.
How we run the project
The detail is where integrations break.
Data mapping
Which data flows, how often, and who owns each field. Without that decision, integration turns into conflict.
Proof of concept
We test the critical path with real data in an isolated environment before committing the whole project.
Development and testing
Built with error handling from the start, tested against the bad cases and not only the happy path.
Go-live and monitoring
A supervised move to production, with alerts configured and fine-tuning through the first weeks.
Protocols and platforms
We integrate with what exists, from modern to legacy.

Frequently asked questions about systems integration
Most of the time, yes — through other routes. Scheduled file import and export, direct database reads where authorised, or an intermediate layer. It is less elegant than an API, but it works. We assess the case before promising.
A simple integration between two systems with decent APIs usually takes 3 to 6 weeks. What stretches the timeline is almost never the code: it is incomplete documentation on the other side, access to a test environment, and the decision on which system owns each field.
The integration has to be built assuming that will happen. We hold undelivered items in a queue, retry automatically with increasing intervals, and alert a human if it keeps failing. Data is not lost and nobody discovers the problem at month-end.
That is the first decision of the project, and it is a business decision, not a technical one. We define field by field which system wins — for example, the ERP owns price and the store owns the description. Without that, both sides overwrite each other and data drifts.
Yes. We build documented REST APIs with authentication, rate limiting and versioning — so your partners can integrate without depending on support, and so a future change does not break whoever is already connected.
It does. Third-party APIs change versions, deprecate fields and alter authentication rules. An unmonitored integration typically survives a few months and then breaks. That is exactly why we work with monitoring and a maintenance contract.
