Billing integration and reconciliation
Payment gateways, accounting systems and ERPs reconciled with the billing run — because billing that does not reconcile with the ledger is a spreadsheet with extra steps.

What billing integration involves
Payment gateway integration
Card, direct debit, bank transfer and invoice payment, with retries, mandates and failure handling defined per method rather than as one generic flow.
Accounting and ERP connections
Billing output posted to the ledger in the structure finance actually reports on, including dimensions such as cost centre, project and legal entity.
Automated reconciliation
Scheduled comparison between the billing run, the payment provider and the ledger, with differences raised as exceptions rather than discovered at the close.
Exception handling and write-offs
Unmatched payments, partial settlements and small differences handled through defined rules, with a queue for the ones that need a human.
Tax engines and e-invoicing
VAT determination across markets and delivery in European e-invoicing formats, which is frequently a precondition for billing large customers at all.
Bank and settlement files
Statement import, payment matching and settlement file generation, with the matching rules tuned to your customers' payment behaviour.

The integration and the reconciliation are the same job
It is tempting to treat connecting the payment provider as the integration and matching the money as a finance task. In practice the matching rules determine what the integration has to carry — references, identifiers, settlement batches — so designing them separately guarantees rework.
We design the reconciliation first and let it dictate what the integration transports. It is a slower start and a considerably shorter month-end.
- Reconciliation-first
- Matching rules decide what the integration carries.
- Exception queues
- Unmatched items surfaced, not buffered silently.
- Ledger structure
- Posted in the dimensions finance reports on.
- Multi-entity
- Legal entities, currencies and tax rules separated.
- E-invoicing
- European formats supported as standard.
- Traceable
- Every posting linked back to its billing line.
A mobile app for DLL, on top of a finance business's existing systems
DLL's mobile app work sat on top of an established finance operation, which meant the integration constraints came first: what the existing systems could expose, how often, and which figures had to agree. That sequencing — system reality before interface design — is how we approach billing integration generally.
Common questions
Which payment providers do you work with?
The ones your markets use. We have integrated European gateways, bank direct debit schemes and invoice payment flows; the choice is a commercial one and we build to it rather than steering you toward a particular provider.
Can you automate our month-end reconciliation?
Most of it, usually. The realistic target is that the routine matching runs itself and the exceptions arrive in a queue with enough context to be resolved quickly — not that a human never looks at it.
Do you handle multi-country VAT?
Yes, either through a tax engine or through rules where the scope is narrow enough to justify it. We are explicit about which approach we are proposing and what it will cost to maintain as rates change.
