I’ve never been paid any other way than monthly. But I think if I were paid more than once a month I’d try setting the summary period to fixed cycles (e.g. 1st to 1st rather than payday to payday) and set custom budget rather than budget based on income. Would this not work for you?
If you do need fortnightly summary periods, there’s already an ideas thread for this
I’m not sure what you mean by add additional regular incoming payments. If I have more than one income payment in a payment cycle they all get classed as income. Perhaps you could explain the issue further and what you think the solution should be.
Given you can set an outgoing payment as recurring and the left to spend takes it into account, could marking an incoming payment bas recurring have an effect?
Combined with setting up the budget to be four weeks long could this be a stop gap solution for you?
Please vote on the linked request above, I also get paid fortnightly (although without extra payments to complicate things) so would love it to happen as I can only believe the left to spend for half the time.
