If you need to do Weekly PAYGW in the Cashflow setting please note, currently Calxa only forecasts on a monthly basis, so setting as Monthly assumes payment in the following month. If you need to you can set a Custom Schedule for 100% current and then it will forecast full payment in the month it is budgeted.
It may also be worth reviewing the percentage amount of the calculation to refine the predicted amount to be paid.
Alternatively, if you settle PAYGW on payday, it may be easier to set to Nil%, and just use the Gross Wages amount as the Cashflow amount as all will be paid at the same time.
