You can create an invoice from other documents such as Purchase order, Pro forma invoice or Estimate.
It's not possible to create an invoice from a Delivery note, because it doesn't contain any prices or taxes. If you'd like to create Delivery notes and Invoices we suggest to create a Purchase order first from which you can create later both.
In the Documents section click on Estimates, Orders or Pro forma invoices
A list of documents appears
Choose the desired document and click on it
A preview appears
In the upper right corner you will find a Create button
Click on the button and select Create invoice
A new invoice is created with the order data
Change the date and details if necessary and click Save
Note: If you don't see the possibility to create an invoice, then an invoice has been already created in the past. You can check the Timeline to see more details.
In the Documents section tap Estimates, Orders or Pro forma invoices
A list of all documents appears
Select and tap the desired document you want to create an invoice from
On the lower black bar tap on More
