For solo founders

Books that close themselves.

Tallymoss is the always-on AI bookkeeper for founders flying solo. It categorizes transactions as they post, chases overdue invoices on your behalf, and flags a cash-flow gap about two weeks before it hurts.

Today from the books

The morning P&L.

Three sentences, pulled live from your two weeks of categorized transactions. The kind of summary you'd write on the back of a napkin — but the books never lie.

Looking two weeks out

The next 14 days.

A day-by-day projection of your running cash balance, walked forward from today using your recent average. Shortfall days — anything that crosses below zero, or drops more than a quarter from today’s balance — get flagged before they become problems.

Why Tallymoss

Quiet, accurate, and a few weeks early.

Built for the operator whose books used to be a month stale and ten hours a month to keep. You stop losing nights to bookkeeping and start rolling into month-end clean.

01

Categorizes as it posts.
Transactions land in your bank or card feed, and Tallymoss labels them on the way in — vendor, category, project — so the books never get stale enough to need a weekend rescue.

02

Chases invoices on your behalf.
When a customer invoice goes past terms, Tallymoss sends a polite reminder in your voice and logs the thread. You only see the ones that need you.

03

Flags a cash gap two weeks early.
It watches your recurring bills and your receivable curve, and pings you before a payroll week gets tight — not the morning after.

04

A P&L you can read over coffee.
Every morning, a plain-English summary lands in your inbox. No dashboard to log into, no taxonomy to memorize, no seventeen tabs open in a half-finished spreadsheet.

A day in the life

What shows up — and when.

The work happens in the background. You see it as one inbox email a day, one polite nudge when an invoice stalls, and one heads-up before a tight week.

  1. 7:00 am

    The morning P&L arrives.

    Yesterday’s totals, what moved, what didn’t, and one sentence on what to know — in your inbox before you’re fully awake.

  2. As it posts

    Every transaction is categorized.

    Stripe, AWS, the $14 lunch, the mystery card charge — each one labelled with the project or category the books expect. Trainable on the edge cases.

  3. +7 days past terms

    Tallymoss chases politely.

    A reminder goes out in your voice. A second follows. You only get pulled in if it’s still open after that.

  4. Day 30

    A human reviews the long tail.

    Algorithms get ~85–95% of the long tail right by month three. A bookkeeper reviews the rest, so month-end is clean, not "close enough."

Pricing

Priced below a part-time bookkeeper. The first month usually pays for itself.

Tallymoss is priced to replace the hours a one-person operator loses to bookkeeping — not just the dollars. At the sub-500-invoice size, that’s the part pure cost-savings rarely clears.
