STATUS QUO
Manual data handoffs cost hours every day.
From working with over 500 companies, we know where it breaks down.
No real-time data
Invoices sit in inboxes or wait for manual handovers before the ERP can process them.
Error-prone imports
CSV exports, manual uploads and incorrect field data regularly lead to rework.
No status transparency
Without automatic feedback it often remains unclear which invoices were processed or delivered.
CORE API CAPABILITIES
One API for the entire invoice process.
Invoices are created, checked, sent and processed through one consistent REST API.
Create, validate, deliver

Status & webhooks
Status updates and feedback are pushed automatically via webhooks.
Receive & Validate
Incoming invoices are imported via the API and validated automatically, validation report included.
