About Fathom

Come see how deep the books really go.

Fathom is software for the people who run small businesses and would rather not become part-time bookkeepers. It reads your accounts, files the paperwork, and tells you what next quarter looks like.

Pick a plan, take the plunge
Why it exists

The month-end ritual deserved a retirement.

Small businesses generate the same data as big ones: payouts, card swipes, invoices, payroll. What they lack is a finance department to wrangle it. So the work piles up in a tab, then a shoebox, then a frantic Sunday night.

Fathom was built around one belief: the repetitive part of bookkeeping is a pattern-matching job, and software is good at patterns. The judgment calls stay with you; the filing doesn't have to.

What we hold to

Three rules we don’t bend.

Look, never touch.

Every connection is read-only. Fathom can see a transaction; it cannot move a dollar. That isn’t a setting you can flip by accident. It’s how the connections are made.

Show the work.

Every suggestion carries a confidence score, and every change lands in an audit trail with a name and a time. If Fathom is unsure, it waits for you instead of bluffing.

Plain numbers, plain words.

A forecast is only useful if you can read it on a Tuesday. We name the lowest point, give it a date, and skip the jargon that makes you nod and not understand.

How it’s built and looked after

Quietly automatic, loudly accountable.

Feeds first

Banks, cards, and invoicing tools are the foundation. Transactions are categorized and matched as they land, so the ledger is current instead of eventually correct.

Guardrails by default

Seats are scoped to view, comment, or export. Approval rules hold back anything over a limit you pick. Year-end exports are always yours to take.

Support that reads your ledger

Write to hello@fathombookkeeping.com and a person who knows the product replies, with your workspace in mind rather than a script.

Where it’s heading

Charting the next few fathoms.

Shallows · now

Cleaner queues

Better confidence scoring so the review queue keeps shrinking and the rules you teach Fathom travel further.

Mid-water · next

Richer scenarios

Compare more what-ifs on one chart: a hire, a lease, a late-paying client, all with the lowest point flagged.

Deep end · later

More places to connect

Additional banks and invoicing tools, plus alerts delivered where your team already works.

Roadmap items are directions, not promises with dates. We’d rather ship it right than ship it Thursday.

Field notes

What people say once the shoebox is gone.

“Read-only was the line I needed. I could connect everything without losing sleep over it.”
— Elena V., Owner, Harbor & Hale Supply
“The audit trail ended our ‘who changed this?’ thread. It answers before anyone asks.”
— Dev K., Finance Lead, Tallow Street Studio
