Hey welcome to Tiller. I was a long time Mvelopes users as well but decided to move away in 2019 after their upgrade to Mvelopes 5. What a trainwreck of a transition. So first off, you can definitely get the same capabilities fromTiller that you had in Mvelopes, and a lot more. Tiller being based on Sheets and now Excel allows the ability to build any tools you need in a spreadsheet. The savings budget sheet is a good sheet, but it is different than Mvelopes. Here are the biggest differences. Mvelopes is a cash flow envelope system that only allows you to fund your envelopes with money that has actually been received. The savings budget is based on the budgeted amounts not the actual balances. Not a huge deal, but it is different and something to know ahead of time. The 2nd difference and somewhat related is the lack of envelope funding tempates. In fact, this is what drove me from YNAB too. I loved being able to use the first paycheck to partially fill my groceries or mortgage envelope and then use my second paycheck of the month to fill other ones. Using a template made the process repeatable and super fast.
Luckily, since it is based on Sheets, I was able to create a new sheet that met all my needs. I call it Ultimate Envelopes. You can read about it here
And you can grab the template here.
If you have any other questions about it or my transition from Mvelopes, just ask. I would be happy to help out.
Good luck and welcome to the community.
