how to manage services contract

[dalescott]

Hi, I'm a newb using webERP for services and now have a 6-month contract for engineering services. I will invoice every two weeks, payment will be made by cheque within 14 days. I need to include an itemization with the invoice giving hours worked each day with comments.

I created an item called "CONSULTING", but am unsure "how" to create the sales order and do partial invoicing. E.g. should I create one sales order for 960 hours, create a sales order for every invoice, or create a contract? I've been experimenting with different procedures (re-loading a backup when I hit a dead end), but would really appreciate workflow suggestions.

Thanks!
Dale
