Q: Why does the bill show a previous balance, when I entered the payment we received from the client?
A: Probably the date of the payment is after the Payments and Adjustments Cutoff Date for the bill.
Let's consider how this might happen. Suppose the client owes you $1,000 for work done in May. In June, no work was done and no payment was received. However, you received and entered a payment of $1,000 on July 5. Now it is July 10 and you want to send out the June bills.
You click the Bills button in RTG Bills. Notice that there are two cutoff dates and they are both set to the last day of the previous month (June 30 in our example). If you use those dates, the bill will not show the payment dated July 5, because it is after the Payments and Adjustments Cutoff Date. The June bill will still show a balance due, even though the client has paid in full.
Technically this is correct, because the payment arrived after the end of June, so it shouldn't appear on a June bill. But you may not want to send a bill showing a balance due when you've already been paid.
The solution is simple: click the Mixed button.
The Mixed button changes the Payments and Adjustments Cutoff Date to today's date. As a result, the bills will include any payments and adjustments that you have entered up to the day that the bills are printed. The Fees and Expenses Cutoff Date is still the end of the previous month, so you won't see any of this month's work on the bill.
