You've received a Purchase Order from your customer, accepted it and now you're ready to issue the invoice. To connect the invoice with the purchase order, all you need to do is write the PO number on the invoice.
Our system will automatically detect this information and link the two documents up. Being able to link POs with invoices is essential. It will enable your customer to control spend and will help you get paid quicker.
If for some reason you have forgotten to add the PO number to the invoice, you can send the information to us via email or chat to us via Intercom (at the bottom right of your screen) and we can help link the documents for you.
