How GeldMeld keeps financial logic consistent

GeldMeld connects payment events to the tax, invoice, evidence, and accounting state your product actually needs.

01

Why a financial control layer matters

A payment is only the beginning. Tax rules, invoices, refunds, evidence, settlements, and accounting handoffs can drift apart when each product handles them differently. Centralizing that context keeps the financial answer consistent.

02

The recommended flow

Send the payment event and business context to GeldMeld, resolve the tax snapshot, create the linked invoice and evidence, and consume the prepared state through the contract used by your finance and product systems.

03

Keep sensitive logic on the server

Provider credentials, tax rules, invoice generation, and accounting preparation belong in controlled backend infrastructure. The client should receive only the financial result it needs.

Integration checklist
  • A server-side payment event endpoint
  • A normalized transaction state
  • A time-valid tax snapshot
  • Linked invoice and customer evidence
  • Idempotent event processing
  • Audit-friendly historical states
  • Prepared settlement and accounting batches
  • Monitoring for delayed or conflicting events
  • A fallback policy for unavailable provider data

Start with one product and one financial flow. Once the state contract is stable, extend the same rules to additional companies, brands, projects, and accounting destinations.
