The thing nobody says
You didn't get into your business because you love spreadsheets. You got into it because you're good at the work — the actual work. Software should respect that.
— Why Thalermark exists
A different kind of accounting tool

Most accounting software asks. Thalermark answers.

Every other tool makes you learn double-entry bookkeeping, journal entries, and chart of accounts. Thalermark watches your business and tells you what matters.

The old way

"Would you like to create a journal entry? Please select an account from your chart of accounts and enter the debit and credit amounts."

Thalermark

"You have 3 unpaid invoices totalling $1,240. Two are over 30 days. Want me to send reminders?"

What it does

Five things, done well.

No feature creep, no learning curve. Just the core of running a small business — handled the way it should have been all along.

01 / Invoices

Send an invoice in under sixty seconds.

From your phone, between jobs. Stripe link attached. Track delivery, see when it's opened, get notified the moment it's paid.

02 / Expenses

Snap the receipt. We'll handle the rest.

AI reads the receipt, picks the category, files it correctly. You confirm with one tap or let it auto-file based on your history.

03 / Position

One screen tells you exactly where you stand.

Money in. Money out. What you're owed. What you owe. No charts you don't understand. No accounting jargon. Just the numbers.

04 / Insights

The AI watches the cycles you're too busy to see.

"January is your slow month — set aside more in October." "This client pays late 80% of the time." Plain English, drawn from your own data.

05 / Taxes

Quarterly tax estimates, not surprises.

US-first by default. 1099 awareness. Self-employment tax estimated as you go. No financial advice — just awareness, so April never blindsides you.

06 / Privacy

Opt-in telemetry. Open source. Your data is yours.

We collect anonymous usage data only if you say yes. The code is public. The spec is published. You can audit every line.

Who it's for

For the people who show up and do the work.

If you're great at your craft but accounting feels like a second job you didn't ask for — Thalermark is built for you.

The principles

Open source. AI first. No paywall traps.

Thalermark is built in the open. The community can audit every line of code. The premium tier exists, but the core is yours to keep — forever.

01.

Free and self-hosted, forever

Run the full open source version on your own server with a single docker compose up. Core features stay free. No bait-and-switch.

02.

Pay for time and intelligence

Our managed cloud and AI insights tier exist for people who'd rather not run servers. Reasonable pricing, no rent-seeking.

03.

Telemetry is opt-in, always

If you let us see how the product is used, we publish what we learn. The telemetry code is open, the data is anonymous, and you can turn it off in one click.
