Idea: post the six invoices (with different dates? ...or one big invoice for the 6-month term), and process the lump sum Cash Receipt against those posted invoices.

You could also process the cash receipt as a pre-payment, and apply the PP to invoices as you go, but that involves extra data entry steps... and would only make sense if you don't know what the monthly invoices look like in advance (or you are not shipping inventory all at once).

Repetitive invoices are for making data entry easier with virtually duplicated invoice data... independent of considerations for how those invoices are paid.

We create one sales order, let's say for 12K (posts against incoming orders) then when billed we will most likely bill the total amount with 6-month terms. These customers want to pay their bill by ACH in 6 monthly payments. Thats where the confusion begins because our accounting dept has to remember to go in and ACH the funds from the customer each month. I may check to see if we can set up reoccurring ACH draws from the bank,

DSD has an enhancement for multiple due dates for an invoice, if you think that would help.  SO-1241

That may work! I'll check it out Thanks!!
