Walled months, walled months, walled months. Red Arrow. Scheduled transactions. Feature rich/feature friendly for various work flows.
I have a big screen at home and I'm not seeing 2 months -- I'm seeing 7 or 8. Do I need to see that many? No. But seeing 3-4 is extremely helpful.
It's not just seeing them but working with them. I am over 1.5 months buffered. On the 15th I'll have March's budget completely filled. The numbers for filling the categories are already there-- I'm making decisions with unexpected income (a bonus, etc.) in the present in anticipation of the future. I have fairly regular income currently and have filled in the majority of the walled months for the year. Yes, April and beyon have big ugly red numbers in them-- the only big pain is that my cable bill shifted and I had to reenter the majority of the months (or at least a few ahead to keep my eye on the estimated budgets for the next few months with expected bills and dole out).
I can keep the zero sum budget on the current month and make decisions this month. I can complete the budget next month and be ready to spend from it when the date rolls over-- but I'm kept honest with the spending on the categories this month.
Seeing the future helps me look to the future with the walled months. I avoid spending future money but having the visibility for "expected" and "accumulated" categories to see if I'm hitting my targets is hugely valuable-- perhaps the goals in nYNAB would work-- they weren't there when I was exposed to a single month nYNAB early product (or they were in infancy but I was so blown away by lack of walled months my first reaction was "where's my stuff!?").
nYNAB is not focused on features-- it is focused on a specific usage. And it isn't mine.
I used to be pretty sloppy on reimbursements. But now I can handle them in a timely matter and as I look at my budget daily it shouts at me that I haven't sent or received reimbursement-- the category is red. Since I'm buffered and accounts are healthy I'm not bothered by it being red or feel I'm dishonest on actual money. It's red because I need to do something for that specific category and that doesn't affect the rest of my plans nor spending.
I'm all in for adoption of financier-- it seems faster and I too like the customizations (not there yet with trying them out but I will be). Features and options for viewing and work flow are signfiicant. Each budget is different. What nYNAB did is practically equivalent to having locked pre-set categories. Can you make your budget work with predefined categories that you can't customize? Probably. Would it feel like "your budget"? No... it would feel like you're a part of their budget and robotted into it. BOX ME IN? No thank you.
I think I covered the bulk of the key reasons
My workflow is not your workflow-- but we can share ideas and approaches and learn from each other and modify each our own (without workarounds the tool may require).
I've become a huge fan of zero sum budget. I was a huge fan of YNAB4. I'm still using it until features are available with financier.
