Most freelancers lose revenue not because they undercharge — but because they forget to charge at all.
Track time without thinking about it
Start a timer from any project in one click. Every minute lands in the right bucket automatically — no manual sorting, no spreadsheet archaeology at month end.
Turn tracked time into a professional invoice
Select a date range and Billmark assembles the line items. Adjust, add a note, and send. The invoice looks like a real business sent it — because a real business did.
See what you are owed at a glance
Your project dashboard shows active clients, billable hours this week, and every outstanding invoice — so chasing payment is a choice, not a mystery.
How it works
Billing that fits the end of a real workday
Open a project, start the timer
Every client gets its own project with a name, billing rate, and color. Hit start when work begins — Billmark records the clock. No setup ritual, no tab-juggling.
Works on desktop and mobile. One timer runs at a time so there is never a question about what you are billing.
Add context as you go
Label each entry so invoices explain themselves. Write a quick note — 'Homepage mockups, round 2' — and your client sees exactly what they are paying for.
Clear entries reduce the back-and-forth that delays payment.
Generate the invoice
Choose a project and a date range. Billmark pulls every entry into a clean, itemized invoice with your business name, the client's details, your net terms, and a professional total.
Nothing to format. Nothing to calculate. Ready to send in under a minute.
Send and get paid
Send the invoice directly from Billmark or export it as a PDF to attach to an email. Either way, the paper trail is yours.
Outstanding invoices surface in your dashboard so you always know what is still open.

Questions
Straight answers
- Do I need to upgrade to track more than one client?
- No. Billmark lets you create and manage multiple client projects. Track time across as many clients as you work with.
- Can I track time manually if I forgot to start the timer?
- Yes. Any time entry can be added manually — just pick the project, enter the start and end times, and add a description. Manual entries appear in invoices exactly like tracked ones.
- What does a Billmark invoice actually look like?
- A clean, line-item invoice with your name and contact details at the top, the client's details, a description column, hours, rate, and a clearly calculated total. Professional without being over-designed — the kind of thing a client actually reads.
- I work on projects rather than by the hour. Can I still use Billmark?
- Yes. You can set a fixed fee on any project and still log time against it for your own records. The invoice reflects the fixed amount rather than an hourly calculation.
- How do I handle invoices for clients in different currencies?
- You can set a currency per client. Billmark generates invoices in that currency — useful for US freelancers who occasionally work with international clients.
- Is there a desktop app or does it only work in the browser?
- Billmark runs in the browser on any device — desktop, tablet, or mobile. No install required. Your data syncs automatically so the timer you start on your laptop shows up on your phone.
