Common questions
Can I send a multipage document?
Yes. Upload the PDF and the app checks its pages when preparing the quote. The approved total includes the document and selected options.
Can software prepare a flat-envelope order?
Yes. The REST API and MCP product catalog expose the flat product and its quote workflow. Sending still requires authorization.
