Banking Systems Integration in Durham
Connecting the core to everything around it for Durham banks — channels, payments, cards, lending, reporting. The rule that governs the work is that the ledger is the authority and nothing else may hold a balance. Systems that cache a figure for speed and later disagree with the core are how reconciliation breaks become customer-facing.
Why this comes up
The problem
Six systems each hold a version of the customer's balance, and the one the app shows is not the one the ledger says.
What you get
What we deliver
- The core treated as the single source for balances and postings
- Surrounding systems reading rather than holding their own version
- Batch cut-offs respected, since end-of-day is a real boundary
- Reconciliation between systems run as a control with breaks investigated
- Structured payment data carried through rather than truncated in transit
- Replay and idempotency handled so a retry cannot post twice

Working in Durham
North East
Durham's economy is dominated by its university and cathedral, so the commercial base is small and much of the local demand comes from spinouts and suppliers attached to the institutions rather than from independent industry.
Research spinout software and visitor systems, usually on institutional procurement timelines rather than commercial ones.

Banking Systems Integration in Durham — common questions
- Why does the cut-off cause so much trouble?
- Because systems disagree about which day a transaction belongs to. A payment accepted at one minute past the boundary posts tomorrow in the core and today in the channel, and the customer sees a discrepancy that is not an error but is indistinguishable from one.
- What breaks with payment message standards?
- Data loss at the joins. Richer structured formats carry party details and remittance information that older internal systems cannot store, so the fields get flattened into a free-text line — which defeats the reason for adopting the standard in the first place.
- How do we stop duplicate postings?
- Give every instruction an identifier the receiving system honours, so a retry after a timeout is recognised rather than processed again. Timeouts are normal at this scale, and integrations without idempotency create duplicates that are then removed by hand.
- Should reconciliation be automated?
- The comparison, yes. The investigation, no. Automated matching should shrink the exception list to genuine breaks and put those in front of a person with the detail needed to resolve them — a control that clears itself is not a control.
- Do you work with businesses across County Durham?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout North East, including Durham and the surrounding County Durham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Durham businesses do you usually work with?
- Research spinout software and visitor systems, usually on institutional procurement timelines rather than commercial ones. Beyond that we work across Higher Education, Tourism & Heritage, Public Sector, Retail and Research.
- Do you cover the areas around Durham?
- Yes — we work throughout North East, including Newcastle, Sunderland, York. Durham is an urban area of roughly 70,000+, and we take on work across the wider County Durham region rather than the city boundary alone.
