Not budgeting as such but like you I have a spreadsheet running too, Neo Office rather than Mariner. There are just some things spreadsheets do better.
I have most regular payments set up with my bank.
Monthly Power, Telephone & Insurance policies via direct debit.
Fortnightly transfers to savings and other accounts from the main a/c the salary gets deposited in.
All salaries, wages, benefits, pensions etc are direct credited to bank accounts here in NZ. No cheques to cash or bank.
Would just really like to be able to post any scheduled payments due before the next fortnightly salary date.
Must be difficult writing the software though, everyone runs their budgets in different ways and although I have no need for cheques, checkbook suits me well.
