System Integration in Derry
Connecting the systems a Derry business already runs so information moves between them without a person in the middle. The decision that matters most is which system owns each piece of data — integrations that skip it produce two systems overwriting each other and nobody able to say which is right.
Why this comes up
The problem
The CRM, the accounting system and the operations tool each hold a version of the customer. Staff rekey between them, the versions diverge, and reconciling is somebody's weekly job.
What you get
What we deliver
- A system of record agreed per data type, so precedence is decided not discovered
- Field mapping documented, including what does not map and what is deliberately dropped
- Sync direction chosen per field rather than bidirectional everywhere by default
- Conflict handling defined for the cases where both sides changed
- Error visibility, so a failed sync reaches a person rather than a log file
- Reconciliation reporting, proving the systems still agree over time

System Integration in Derry — common questions
- Should syncing be bidirectional?
- Rarely for every field. Two-way sync means deciding what happens when both sides change, and most projects discover that question after a customer record has been overwritten. Choose direction per field — most data has an obvious owner once you ask.
- What is a system of record and why does it matter?
- The system whose version wins for a given data type. Without one agreed, every sync conflict becomes an argument, and the integration quietly encodes whichever answer the developer chose that day.
- Real-time or scheduled?
- Scheduled batches are simpler, cheaper and adequate for most business data — nightly is fine for a great deal of it. Real-time is worth its complexity where a delay has an actual cost, which is less often than it is requested.
- How do we know the integration is still working?
- Alerting on failure, and periodic reconciliation comparing record counts and key values across systems. Integrations fail silently far more often than loudly, and the discovery usually comes from a customer rather than a monitor.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
