A billing department in a box.

Everything a finance team does for a big company — chasing, billing, getting you paid — built for a team of one.

Get paid before you start

Send a request link. Clients submit what they need, you price it, they pay to confirm.

Bill however you work

Hourly, daily, flat fee, or per item — switch with one tap, in any currency.

AI invoicing

Say what you did in plain words and the invoice builds itself — line items, totals, dates.

Online payments

Card and bank transfer, in the currency you bill in. No per-transaction platform fee.

Your logo on invoices

Branded invoices and emails that make a team of one look like a real company.

Payment reminders

We send the awkward email
so you don't have to.

Asking for money feels personal. Atomic Works handles it — drafting follow-ups in your exact writing voice, escalating professionally, automatically. No templates. No robot speak.

Just your words, at exactly the right moment.

Written in your tone, based on how you actually write emails.

Job requests

Let clients request work — and pay first.

Send a link to any client. They describe what they need — no account required. You set the price and send it back. They pay to confirm. Job added to your queue. No back-and-forth. No chasing.

  1. 1Send link
  2. 2Client submits
  3. 3You approve
  4. 4Client pays
  5. 5Job queued

The request is the trigger. The payment is the handshake.

Your invoicing assistant

Say what you did.
We'll build the invoice.

Describe your work in plain language — by type or by voice — and Atomic Works fills in line items, amounts, due dates and client info automatically. Review, tweak, send.

"Monthly retainer for Studio X, $2,500, April"
"Website build for Mike — $3,200, 50% deposit paid"

Flexible billing

Bill however you work.

Charge by the hour, by the day, a flat fee, or per item — and invoice in any currency. Your billing flexes to the job, not the other way around.

USD, EUR, GBP, CAD, AUD and more — set per invoice.

Why Atomic Works

Everything a billing department does.
None of the overhead.

Big companies have teams managing invoices, chasing payments, tracking clients. Now you do too — without the salary, the office, or the corporate BS.

Follows up for you

Reminders drafted in your voice, escalating professionally — so you never write the awkward "just checking in" email again.

Tracks everything

Client payment scorecards, revenue trends, and outstanding pipelines — the same visibility big companies have, for your business.

Looks like a real company

Clients receive polished, branded invoices with online payment links. You look established — whether you're a team of one or one hundred.

This used to cost thousands per month in software and staff. Atomic Works charges $12.

Enterprise billing tools.
Not enterprise prices.

FreshBooks starts at $33/mo. Wave is free — but holds your funds and charges more per transaction. Atomic Works is $12, and does what neither can.
