API Integration

Granular role and permission settings ensure only authorized personnel can edit invoice templates, send for signature, or approve payments, supporting segregation of duties.
Optional two-factor authentication strengthens signer identity verification for high-value invoices or those subject to internal compliance checks.
Customizable fields capture PO numbers, GL codes, project IDs, and other client-specific metadata to match corporate accounting requirements.
Configurable retention and archival rules support corporate records management and legal hold requirements for financial services documentation.
Prebuilt connectors for accounting and storage platforms reduce setup time for invoice routing, storage, and accounting reconciliation.
Prebuilt invoice templates let teams standardize line items, GL code fields, and approval workflows so each invoice conforms to corporate procurement and accounting requirements.
Send multiple invoices at once to different recipients using CSV lists, enabling mass distribution while preserving unique fields and recipient-specific data for faster batch approvals.
Embed payment links, ACH or credit card options within the invoice to capture deposits or final payments and reduce reconciliation time between invoices and received funds.
Maintain a tamper-evident audit log that records who viewed, signed, and modified the invoice, with timestamps to support internal controls and external audits.
