Accounting API

Expense reimbursement and financial reporting currently require manual data entry into separate accounting systems, creating administrative burden and error risk. Automating this data flow eliminates double-entry, reduces processing time, and ensures financial records are accurate and timely. For HLF and Blindeforbundet - the two organizations with explicit accounting integration requirements - this directly reduces staff hours spent on reconciliation. The unified API abstraction means future organizations with different accounting systems can be onboarded without code changes, supporting the platform's multi-tenant scalability goals.

The integration uses a pluggable AccountingApiGateway infrastructure component accepting a provider configuration per organization. Each provider (Xledger, Dynamics) implements a shared interface, with organization-specific credentials stored as encrypted tenant configuration. AccountingApiClient handles authentication, request signing, and error handling. AccountingIntegrationRepository persists sync state and transaction IDs to support idempotent retries. All outbound calls are recorded in the audit trail for compliance. The gateway implements retry logic with exponential backoff for transient failures.
