Nanonets tells you to check every row against the PDF. A bank statement already prints the answer.

The best Nanonets alternative for bank statements is one that checks its own work against the balances printed on the statement, so you don't have to compare rows with the PDF by eye. ZeraBooks does that on every statement, per account, and only marks it proven when it ties to the cent. I founded ZeraBooks; the Nanonets facts below are from Nanonets' own pages, read on November 5, 2026.

What does Nanonets say to do after it converts a statement?

Nanonets' bank statement converter page claims "99%+ accuracy" without saying how that's measured. Each extracted transaction links back to its spot on the statement, which they call "Verify with source links". Exports are XLSX, CSV and JSON.

Then the FAQ says the quiet part. Review and validate the data by comparing the rows against the original PDF. It calls that step crucial.

I agree it's crucial. I just don't think a person should be doing it row by row.

Why is the statement's own balance a better check than your eyes?

Because the bank already did the math. Every statement prints an opening balance and a closing balance, and most print a running balance too. If opening plus every row equals closing, nothing was dropped, doubled or flipped. If it doesn't, the gap usually tells you which row:

The gap isUsually means
Twice one row's amountThat row's sign is flipped
Exactly one row's amountThat row is missing or doubled
One of the printed totalsA subtotal was read as a transaction
A small multiple of 9Two digits are swapped

A person comparing 300 rows with a PDF will miss things. Arithmetic won't. Nanonets' page doesn't mention a check against printed balances, so as far as I can tell from what it publishes, that's still on you.

What does that look like in ZeraBooks?

Three statements from three banks in our test set (Wells Fargo, Monzo and Navy Federal samples), each proven against its own printed balances, then downloaded as one file:

ZeraBooks Convert with three statements chosen, each proven to its printed balances, ready to download together

The Navy Federal one has two accounts in one PDF. Each account gets its own proof.

What does it cost?

Nanonets prices in credits on an AI workflow platform. Starter comes with $50 in credits, then $100 a month for 100 credits. Block runs cost $0.02 (simple), $0.10 (standard AI) or $0.30 (complex AI, which is where data extraction sits). The pricing page doesn't publish a price per page or per bank statement, so I can't tell you what a statement costs there.

ZeraBooks is priced per page: 1,000 pages a month for $79 billed annually or $149 monthly, with a 7-day trial. That's the number you put in an engagement letter.

The full comparison is on our Nanonets alternative page.

If a tool tells you to double-check its work, ask why it didn't.

How to clean up messy books without redoing the same month twice

Image
Clean up books in this order: collect every statement , set opening balances from the last period your accountant signed off, then reconcile each account one month at a time, oldest first . Only once a month ties do you pair transfers, remove duplicates, place uncategorized lines and move owner spending out. A different order means categorizing lines you later delete. A month that doesn't tie, with the gap shown. During a cleanup you stay on that month until the gap is zero. The worked figures below belong to a fictional design studio whose books stopped being kept in February. They are illustrative only. What has to happen before any categorizing? Step 1: Build a statement grid Accounts down the side, months across the top. Tick a cell when you hold that month's statement as a PDF from the bank. Our studio has checking, savings and one card across eight months, so the grid has 24 cells. Any blank cell is a month you can't prove yet, so request it today. Activity...

How to convert a credit card statement PDF to Excel, step by step

 You need last quarter's card charges in a spreadsheet by Friday, and all you have is three PDFs from the issuer's website. To convert a credit card statement to Excel, download the PDF statement (not the activity export), run it through a converter or copy the tables out by hand, then fix three things: the signs on payments, the foreign currency detail lines, and the summary blocks. Finish by checking that your rows rebuild the printed new balance. Here's each step. Step 1: Download the statement PDF Go to the card's statements page on the issuer's site and download the monthly statement. Many issuers also offer a "download activity" CSV. Skip it for this job. It usually has no previous or new balance printed anywhere, and those two numbers are how you'll prove the spreadsheet is complete at the end. Watch the dates. A card statement ends on a closing date, not the end of the month. If you need the full quarter, you may need the statement after it too...

How to scan a bank statement so it converts to Excel cleanly

Image
To scan a bank statement so it converts to Excel cleanly, use 300 dpi and grayscale , keep pages straight, save each account's pages into a single PDF , and include the last page even if it looks empty. Then convert it and check that the opening balance plus the rows equals the printed closing balance. Most conversion problems with scanned statements are decided before the conversion starts, at the scanner. Here is how to get it right, step by step. Where a scanned PDF goes in ZeraBooks Convert: the Upload button, or drop the file on the page. Do you need to scan the statement at all? Step 1: Check online banking first Log in and look at the statements section. If the month is there, download the PDF. A downloaded statement carries the bank's own text and will always beat a scan. What scanner settings work best for bank statements? Step 2: Set the scanner Setting Use Why Resolution 300 dpi Lower loses faint digits; higher only makes bigger files Colo...
