Banking Systems Integration in Brighton
Connecting the core to everything around it for Brighton 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

Banking Systems Integration in Brighton — 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 East Sussex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Brighton and the surrounding East Sussex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Brighton businesses do you usually work with?
- Design-led briefs from a market that judges craft closely, plus hospitality and visitor systems for the local economy. Beyond that we work across Digital & Creative, Tourism & Hospitality, Higher Education and Retail.
- Do you cover the areas around Brighton?
- Yes — we work throughout South East, including London, Southampton. Brighton is an urban area of roughly 290,000+, and we take on work across the wider East Sussex region rather than the city boundary alone.
