FROM BEHIND TO INVESTOR-READY
How does a startup go from months behind to closed books?
The usual story: the founder kept a spreadsheet, then stopped. Here is how ZeraBooks gets you current.
- 1
Send the statements
Download each bank and card statement as a PDF since your last clean month, or since incorporation.
- 2
We set up and catch up, free
On a 15-minute call we set up your chart of accounts and opening balances and load the months.
- 3
Ask Zera closes each month
Statements are imported oldest first and checked against their printed balances; each month is reconciled and signed off when it ties.
- 4
Share the reports
The P&L, balance sheet and cash flow come from the closed books, so the numbers stop moving once a month is signed off.

What accounting software do startups use?
Early startups often start in QuickBooks or Xero, or in startup-focused tools like Puzzle and Digits. ZeraBooks is for founders who want the AI to close the books rather than draft them.
Do startups need accrual accounting?
Investors and auditors usually expect it once you have revenue and payables. ZeraBooks drafts month-end entries in a double-entry ledger; your accountant decides the basis.
Can ZeraBooks handle payroll for a startup?
No. ZeraBooks has no payroll; keep your payroll provider and ZeraBooks categorizes the payroll payments it finds on your statements.
How does ZeraBooks compare with every AI tool?
Side by side with Digits, QuickBooks, Xero, Puzzle, Booke, Zeni and Rillet on the best AI accounting software hub, where it ranks first.
