Assuming you are referring to the budgeting software, Mvelopes:
Mvelopes is a personal finance application that helps users manage their spending and save money. The app uses the envelope budgeting system, which means users allocate a set amount of money to each spending category (envelope) every month.
To fund your envelopes, you will need to first link your bank account(s) to Mvelopes. Once your account(s) are linked, you can then set up rules for how much money should be allocated to each envelope. For example, you may want to allocate $500 to your 'groceries' envelope and $200 to your 'entertainment' envelope per month.
You can also manually adjust the amount of money in an envelope at any time. For example, if you overspent in your 'groceries' envelope one month, you may need to take money out of another envelope (such as 'entertainment') to cover the shortfall.
If you have any questions about funding your envelopes in Mvelopes, I recommend contacting their customer support team directly for help.
