Frequently Asked. Questions

Can an outsourced AP specialist release payments?

Only if you choose. By default your AP specialist prepares and documents the payment run while release authority stays with your internal approvers, preserving segregation of duties.

How many invoices can one AP specialist handle?

With automation in place a dedicated ATO AP specialist typically processes 1,500–3,000 invoices per month; volumes are validated during scoping before you hire.
