Here’s how to create a Zap to automate this process:
1. Trigger: New Invoice in FastBill
2. Action: Filter by Supplier
- 	
App: Filter by Zapier
	 	- 	
Action Event: "Filter"
	 
3. Action: Update Invoice with Cost Category
                
     
                                    
            Hello, tahnks for the detailed info.
 
Zapier lists up fields of customer invocie which were created in fastbill itself.
 
It doesn switch to the document inbox and doesnt let me choose supplier invocies.
 
Whats the mistake here?
 
Thanks in advance

	 Apologies for the confusion. 
Zapier’s FastBill integration primarily focuses on customer invoices (invoices created in FastBill for your customers). However, your requirement involves supplier invoices (invoices received from suppliers and stored in FastBill’s document inbox).
It does not natively support accessing or processing supplier invoices from the document inbox. 
My recommendation would be, I am not sure if it would work but just a workaround:
If supplier invoices are emailed to you, use Zapier to forward these emails to a Google Sheet. Then, use another Zap to process the data from the sheet and update FastBill with the correct cost categories.
