Howdy, I say Howdy...
I have this customer, see, for whom I work on an occasional basis doing whatever is required to resolve the current, highest-priority crisis.
Theory is this: I submit a quote for some work to a particular requirement. "Scrub steps, clear dog droppings from yard - 3 days at $1000 per day" for example.
There will be a payment schedule:
Installment 1: Steps scrubbed - 1.5 days
Installment 2: Dog droppings cleared - 1.5 days.
I record my doings in time billing. When I have scrubbed the steps, I print a time billing invoice with details and ship it of. To my eternal surprise, I eventually get paid.
Recently there has been a perturbation to this idyllic cycle. I have been recording times while I wait for the mother of all purchase orders that was meant to span a year. This would save both me and my man a lot of work. Owing to forces on a Wagnerian scale, this did not happen. Now I have six months of dog droppings stacked up under my bed and no money to dispose of them thoughtfully. He asked me to send monthly invoices for the unbilled periods, which I dutifully generated from time billing.
Then he asked for a quote like the above, back dated, and I have received a PO for about half the outstanding balance. I did the Convert Quote to Invoice thing twice and generated an invoice for each installment, split the quote balance across them and sent them off. This is good. I am moderately confident that I will be paid.
However, I now have the original monthly time billing invoices sitting in the Sales Register marked as Open. They will never be paid. What I want to do is assign the Time Billing amounts to the two invoices generated from the quote.
Is there a way to do this? I have read as much documentation as I can stand about this and I seem to be in uncharted waters.
I await your solution with breathless anticipation.
