If you need to do Weekly PAYGW in the Cashflow setting please note, currently Calxa only forecasts on a monthly basis, so you can choose between
Monthly (Following Month)
This assumes budget value for April, will be paid in the following month, May.
Monthly (Following except January)
This assumes budget value for April, will be paid in the following month, May, except for December, which will be paid in February. (No January Payment)
Monthly (Same Month)
If you do PayDay payments, you will want to choose Monthly (Same Month).
If you need to you can set a Custom Schedule for other options that the presets do not cover.
It may also be worth reviewing the percentage amount of the calculation to refine the predicted amount to be paid.
