Time tracking & invoicing for freelancers

Stop losing money between the work and the invoice

Billmark tracks your time by client, turns hours into invoices instantly, and keeps your billing organized so nothing slips.

What Billmark does

Built for one person doing the work and sending the bill

Most time trackers are team products shrunk down for a solo user. The projects are designed for managers. The reports are built for admins. The invoice flow is an afterthought bolted on at the end.

Billmark closes that gap. Log time against a client and project. When the week ends, open a draft invoice with every hour already filled in. Review, adjust if needed, send. That's the whole workflow — nothing you don't need, nothing missing.

Track

Log billable hours by client and project, with notes that carry into the invoice.

Invoice

Turn a week of hours into a polished invoice in one step. No copy-pasting, no spreadsheet.

Get paid

Send invoices directly from Billmark. See what's outstanding and what's been paid at a glance.

Time tracking

A timer that knows which client to bill

Start a timer against a specific client and project. Add a note if you want to. Stop it when you're done. Every session is stored under the right client automatically, so you never have to re-sort anything at invoice time.

One-click start

Pick a client and project from your list. The timer starts immediately, no setup required.

Organized by default

Sessions are grouped by client and date automatically. No folders, no tags, no manual sorting.

Manual entry too

Forgot to start the timer? Add a manual entry with start and end times. Everything flows into invoices the same way.

Invoicing

Hours to invoice. One step.

At the end of a billing period, Billmark pulls every logged hour into a draft invoice. The line items are already filled in — client name, project, hours, and your rate. Review it, make any adjustments, and send. No spreadsheet, no copy-pasting from a timer app into a PDF template.

Pre-filled line items

Every tracked session becomes a line item with the project name, duration, and rate already in place.

Send directly from Billmark

No downloading a PDF and attaching it to an email. Send the invoice from within the app — the client gets a clean, professional link.

Payment status tracking

Mark invoices as paid when the money arrives. Billmark keeps a clear record of what's outstanding and what's been settled.

Client overview

See exactly where your billing stands

The client view shows every active client with their hours for the month, outstanding invoice totals, and payment status. You know immediately who has paid, who has an invoice waiting, and who needs one created.

No digging through email threads. No spreadsheet cross-referencing. The information you need to run your freelance billing is in one place, updated as you work.

How it works

A workflow that fits how freelancers actually work

01

Track your time

Start a timer when you begin work. Pick a client and project from your list. Add a note if the task needs a description on the invoice. Stop it when you're done. Repeat throughout the day.

02

Generate the invoice

At the end of a billing period, open a draft invoice for any client. Billmark has already pulled in every logged session as a line item. Adjust if needed, then send. The client receives a professional invoice with your details.

03

Get paid, stay organized

When the payment arrives, mark the invoice as paid. Billmark tracks payment status across all your clients so you always know what's outstanding, what's been settled, and how your billing month is going.
