Hello community. I need advice on controlling expenses for marketing, IT consulting, and auditing. Everything is clear with product invoices - there's a warehouse receipt, but the accounting department pays invoices for services blindly, since reports and reports on work performed are stored in managers' personal emails. Could you recommend software for automating invoices that allows me to set up a strict rule: an invoice isn't sent for approval until it has a supporting report from the project department attached. How do you solve this?
