1. 

Create new Blank Orders with 2 types of Invoicing Policy > Confirm

For example: I choose Corner Desk Right Sit with Invoicing Policy: Delivered quantity and Chair floor protection with Invoicing Policy: Ordered quantity

2. 

Create new Invoice for Blanket Order > Confirm 

For ex: I choose 50% 

3. 

Create new quotation > Edit quantity or take it inherit from blanket orders > Confirm> Go to Delivery 

4. 

Deduct quantity > Validate > Create backorder > Go back SO > Create Invoice > Choose Deduct Downpayment Sale Agreement > There're 4 types to choose > Fill the qty of Deduct amount 
For ex:  I create fixed amount 50$ 

4.1 Fixed Amount 

It will create new Invoice (50$) for Blanket Order and regular invoice for SO (based on Delivery) 

Noted: Product with Ordered quantity automatically invoiced full quantity

4.2  Percentage of Order

Go to delivery > Edit quantity > Validate > Go back to SO  > Create invoice > I choose 10% percentage of order > It also will create new Invoice for Sales Agreement and regular invoice for Sales Order

Go back to Sales Agreement > new invoice lines created with amount: 240$ (based on amount of sales order) 

4.3 Percentage of Invoice

Go to Delivery > Edit quantity (I set 2 for each product) > Validate > Back to SO > Create new Invoice 

I set 20% Percentage of Invoice > It also create Invoice for Sales Agreement and regular Invoice for SO 

Go back to Sales Agreement > New Invoice 360$ created

It based on the Invoiced quantity ( 2 with corner desk right sit - delivered invoicing policy and 8 with chair floor protection - ordered invoicing policy) (2*100+8*200)*20% = 360$

4.4 Balance

Go to Delivery > Edit quantity or you can validate all quantity > Go back to SO > create new invoice with type: balance > It will create new invoice for both Sales Agreement and SO 

Go back to Sales Agreement > Invoice button > New Invoice created based on remaining balance payable 850$

To pay: 1.500$

Draft invoice : 50$ + 240$ +360$ = 650$

=> Balance:  1500$ - 650$ = 850$
