How do I apply a Vendor bill to a Customer invoice?

Hello Vijay, thanks so much for your response! I appreciate it.

Will there ever be a feature to streamline this? Sounds like there should be a more elegant way to accomplish swaps. 

We have a situation where freight vendors frequently come with their equipment unprepared and need to be sold goods and services as part of the shipment they are taking receipt of. For instance we may need to install scaffolding on their trailer to accept our material being shipped. In these cases we deduct from their AP Bill whatever the cost of these materials & services were. However, this should technically be a sale to that vendor and the resulting AR should be applied to the bill (for proper accounting). Given that the system is too rigid in its distinction between payables and receivables and there is no way to simply apply sales proceeds to an AP Bill, the cost and complexity of implementing this process seem to outweigh their benefit and thus we deduct from the AP Bill instead (which is not a great solution). 

Did you find a workflow for this? We sell concrete equipment and sometimes have customers trade-in an old piece for a reduced price on a new one. We’ve extended the customer as a vendor, received the trade-in, and now have a “bill” that needs to be paid. On the flip side, we have an invoice that was reduced by the dollar amount of the trade-in. We’re struggling with how to tie these two documents together and the suggestion above seems like it’s a workaround.
