Real books, every card and live budgets, in one ledger.

Autessa Accounting is accounting software for startups that combines a double-entry general ledger with spend management. It syncs Mercury, reads statements from any bank, codes every transaction for one-person approval, runs department budgets with automatic card guardrails, records bills and invoices, reconciles, closes the month and produces financial statements.

Yes. With a Mercury API token, Autessa Accounting syncs your accounts and cards every 15 minutes, issues virtual cards, changes limits, freezes cards, pays bills by ACH, check or wire, and writes your category and note back to Mercury. The token is kept only in Accounting’s Mercury tools; Accounting stores just its last four characters.

No. Skipping Mercury is a first-class choice: track cards from any bank and upload CSV, Excel or PDF statements. Everything else, review, budgets, ledger, reconciliation, close and reports, works the same. Tracked cards are watched and alerted on, but only the issuing bank can block a charge.

Yes. Every transaction writes at least two ledger lines that balance, on a chart of accounts with assets, liabilities, equity, revenue and expenses. A posted entry is never edited or deleted; corrections are reversing entries that stay visible, and closed months can only be corrected that way.

In a fixed order, cheapest first: the card’s own department, project and default category, then your merchant rules, then a suggestion from Autessa’s AI. Suggestions are never applied on their own. A person approves every row, and confirming a category can write a rule so that merchant is coded automatically after that.

Yes, on Mercury cards. Every 15 minutes Accounting compares each department’s card spend with its monthly budget. Past budget it can notify, lower each Mercury card’s limit to what is left, or freeze the cards, and it undoes those changes when a new month starts or the budget is raised.

Yes. Agent cards are small, single-purpose cards with an accountable owner, a limit (Accounting suggests $100 a month and warns above $500), allowed merchants, a per-charge cap and an expiry date. A charge outside the rules raises an alert on Home and can freeze the card.

All the core financial statements and the reports a startup runs on: profit and loss, balance sheet, cash flow (indirect method), department and budget variance, burn and runway, spend by category, trial balance, A/R aging and A/P aging. Reports export to CSV, and project profit is shown under Projects.

It works alongside your payroll provider and tax preparer. Autessa Accounting keeps the books, manages spend and produces the reports your accountant or tax preparer needs, including 1099 tracking on vendors.

Yes. It ships with a startup chart of accounts, categories and a guided setup, so you can connect Mercury or upload a statement and start coding transactions on day one. Then shape it to how your company works: extend the chart of accounts and categories, write merchant rules, set departments, budgets and guardrails, and, because it runs in Autessa, tailor its workflows, AI agents and look on the same platform.

Anyone with an Autessa sign-in that an administrator adds. Roles add up: Bookkeeper, Accountant, Controller and Admin. Everyone else sees Home, the cards they hold, their own card requests, reports and help.
