CRM integration and synchronisation
ERP, billing, cash registers, receipt systems and marketing tools connected to the customer record — two-way, event-driven, and reconciled so the numbers agree when somebody checks.
What customer integration work involves
ERP and billing integration
Customers, contracts, invoices and balances kept in step between the CRM and the systems that actually bill, so support can answer a payment question without a second login.
Cash register and receipt systems
Till transactions attributed to the right customer within seconds, including the awkward cases — a card used by two people, a purchase made before the card was registered.
Marketing automation platforms
Segments, consents and campaign responses exchanged with the marketing stack, with consent always read from the owning system rather than cached indefinitely.
Support and ticketing tools
Tickets and interaction history visible against the customer record, so the sales conversation knows about last week's complaint.
Two-way synchronisation
Conflict rules defined per field, with a clear resolution order — rather than whichever system happened to write last.
Event streaming between systems
Changes published as events so new consumers can be added later without another point-to-point integration.

Customer work is integration work
Very little of a customer platform project is the customer platform. An address change has to reach billing, the loyalty balance has to survive a till outage, and a consent withdrawal has to stop a campaign that is already scheduled.
We design these flows as events with explicit retry, ordering and reconciliation rules, then add monitoring that reports divergence between systems before a customer does.
- Idempotent
- Repeated events never double-count a balance.
- Ordered
- Out-of-order delivery handled explicitly, not by luck.
- Reconciled
- Scheduled comparison runs report divergence early.
- Observable
- Every exchange traceable end to end.
- Resilient
- The till keeps working when the CRM does not.
- Extensible
- New consumers subscribe instead of being wired in.
Back-office systems that had to match what happened in the car
For Tallink Takso we built the back-office systems behind the taxi operation, where dispatch, the meter, the driver and the billing side all have to describe the same journey. When those records diverge, the disputes land on the support desk — which is why the reconciliation design matters more than the user interface.
Common questions
Can you integrate with an off-the-shelf CRM we already run?
Yes. We work with the platform you have — extending it where its APIs allow, and building alongside it where they do not, rather than insisting on a replatform.
Real-time or nightly batch?
Whatever the business case justifies. Loyalty balances and consent changes need to be immediate; a full customer export for analytics rarely does. We usually end up with both, and say clearly which is which.
What happens when one system is down?
Customer-facing operations keep working against the systems that are up, with changes queued and replayed. That is a design decision made per flow, and we state it explicitly rather than assuming everything is always available.
