Let vendors submit their own invoices and keep their own details current, without opening your AP inbox to them.
Upload an invoice directly, where it lands in your AP queue instead of an inbox somebody has to watch.
Submitted, approved, paid — answered without an email to your team.
Upload a renewed certificate of insurance or a W-9 themselves.
Submit updated remittance details for your team to review.
A vendor-submitted bank change sits inert until a staff member reviews and applies it. Paying a vendor is a push of real money to whatever account is on file, and "update our bank details" is the classic fraud, so the portal cannot make that change on its own.
A submitted invoice becomes a bill when your team says so, coded and approved the ordinary way.
A document the vendor uploaded is marked as theirs, so your team knows what they are looking at.
