I am doing a scenario -
Service work order (with material) e.g. Pipe installation. Vendor will use own material (i.e. Pipes)
Suppose service quantity is 10, rate is Rs.10/- (total amount Rs.100/-)
I have to pay him in three steps -
1) After receiving the pipes 60% of total work order amount (i.e. Rs.60/-)
2) After completion of service 20% of total work order amount (i.e. Rs.20/-)
3) After supervision of service 20% of total work order amount (i.e. Rs.20/-)
After receiving the material by vendor, there is no any track .
how can I do that?
