You may use the multiple sale feature in DEAR/Cin7 and in some cases the invoice doesn't sync to Sales Orders in Pencil.
If this happens, we have a very simple solution to sync the invoice to Pencil. Please follow these steps:
- In Cin7, go to your sale order and copy the order number.
- Then to go Pencil -> Sales Orders -> in the top right corner click on "Sync" and paste the order number and click the "Sync" button.
- Wait 20-30 seconds and refresh the Sales Orders page in Pencil and your invoice number wil sync through.
