Ok today happened to be the first time I used the "deposit" field all the way through to completion. Now I do not bother myself with all the different features of QBO but only what matters to me. That being said here is what I found. As I mentioned before I use DAVO to auto debit sales tax from my bank account when QBO sales are invoiced The way this works is at the end of each day QBO sends transaction data for the day to DAVO and it figures out the sales tax. This does NOT work correctly if I use the "receive payment" button to record a deposit(retainer) for the job. I can't explain why that well but the amount of sales tax calculated is always wrong if a invoice is split into multiple payments on different days. That is where the "deposit" box feature comes in handy. I recorded it there this time and DAVO did not take sales tax out that day as it did not get filed on that days transactions reports. Once I recorded final payment months later. The ENTIRE transaction was processed in QBO and DAVO saw it that night as one complete invoice payment in one day. Thereby taking the correct sales tax out. This probably does not answer other people's concerns but It was mine and I am sharing in case anyone else uses this integration.
