Interoperability
Integrations & Interoperability
Civic AP connects to the financial and procurement systems your municipality already uses — eliminating data silos between AP, GL, purchasing, banking, and tax reporting. Purpose-built integrations for the Civic Suite, open APIs for third-party ERP and banking systems, and standard data exchange formats for legacy interoperability. Full source code licence means your IT team has complete access to integration code.
