: Fondo
Fondo closes your books on a schedule you pick: once a month, once a quarter or once a year. An accountant does the work at close and sends you a reporting package when it is finished. Between closes there is nothing to close, so the numbers you are looking at describe the last period Fondo finished rather than where the business is now.
: T:0
T:0 gives you a general ledger that runs itself: AI writes the categorisation rules, a CPA reviews them, and the ledger applies them as transactions arrive. There is no close to wait for, because the books are current to the hour.
If you are pre-revenue and all you need is one clean set of financials for a tax return, Fondo’s annual plan at $950 a year is hard to beat. If you need to know where the business stands on any given day, that is the comparison this page is about.

: Where T:0 is different
T:0 categorizes, posts and reconciles continuously. There is no gap between the dashboard and the financials, and no stretch of the quarter where you are making decisions against numbers from the last one.
T:0’s AI reads your business during onboarding and builds the chart of accounts from it, so a subscription business gets accounts that separate recurring from non-recurring revenue and a payments company gets accounts for processing costs. You review it before anything posts.
T:0 recognizes revenue inside the ledger, tied to the contract and the invoice, with each entry traceable to the source object. Annual contracts, usage-based pricing and deferred revenue are handled in the books rather than in a spreadsheet alongside them.
Each journal entry in T:0 records which rule produced it and what it was applied to, so your accountant can see why a transaction landed where it did without reconstructing the logic.
