Billing plan - DP settlement

hi all,

i made contract $100,000, then my client want to pay DP 20% from contract ($20,000). cust pay DP 20,000

$100,000 in contract is divided into 5 sales order, each $20,000.

because cust has paid DP $20,000, i want every invoice (from sales order) has partially DP settlement

so, its gonna be

SO 1 -> Billing 1 = $20,000 - DP settlement (4,000)

SO 2 -> Billing 1 = $20,000 - DP settlement (4,000)

SO 3 -> Billing 1 = $20,000 - DP settlement (4,000)

SO 4 -> Billing 1 = $20,000 - DP settlement (4,000)

SO 5 -> Billing 1 = $20,000 - DP settlement (4,000)

*remember, DP is created referenced to contract, but DP settlement happen in billing referenced to sales order

please kindly your advice.

Best Regard,

Hendry
