freelancers and studios track their time with TimeOS. On the Notion Template Gallery and Gumroad · Featured on Product Hunt.
Turn your TimeOS time sessions into a beautiful, editable invoice.
Track your hours in the TimeOS 2.0 Notion template, then hit Generate PDF. This app reads your sessions live, groups them into line items, and renders a clean A4 invoice you polish in the browser — no manual math, nothing to keep in sync.
Prepare in Notion
Create an invoice in the template, set the client and billing period, then press Load to pull that period's sessions.
Generate PDF
Click the template's Generate PDF button — it opens this app on that invoice. Authorize Notion once, read-only.
Polish & export
Group, rename, merge and reorder live, then download a send-ready A4 PDF that foots to the cent.
Everything in the editor
Read-only by design
Notion owns the facts; the app reads them live and never writes back. No hours, rates, or client details touch a server — only your layout edits, per invoice, reset any time.
Zero-config discovery
Point it at one invoice page — it follows Notion relations to find every database it needs.
Three groupings
View line items by Tasks, Milestones, or Projects — each tab remembers its own edits.
Inline editing
Rename any line item in place. Enter saves; clearing restores the original Notion name.
Merge & reorder
Combine several rows into one line, unmerge later, drag to reorder, or sort by amount.
Per-client billing
Three clients in one month? Each invoice pulls only its client's work for the period — bill them separately, with confidence.
Multi-currency
Auto-detected from your Hour Rate. Show a symbol or a code.
Resizable layout
Drag and resize the issuer, client, and payment blocks. Saved per invoice.
Ready-to-send PDF
Download a clean A4 PDF that looks exactly like the invoice on
screen, named Invoice-{ID}.pdf.
Sync, edits kept
Pull fresh data from Notion any time — your renames, merges, and layout survive the refresh.
Mobile & touch
Tap to select, long-press to drag, merge by touch. Bill from your phone — no desk required.
See it for yourself
The live editor, running on a real sample invoice — no account required. Rename a row, switch tabs, drag blocks around, then hit download.

Do I need to be technical?
No. Duplicate the template, connect Notion once, and start tracking. Generating an invoice is two clicks.
Will it change my Notion?
Never. The app is read-only — it reads your data live and never writes back. Only your visual edits are saved, per invoice, and you can reset them any time.
Can I bill several clients in the same month?
Yes. Each client gets its own invoice from the same period. Just avoid overlapping invoice periods for the same client.
What currencies does it handle?
It reads the currency from your Hour Rate and shows it as a symbol ($/£) or a code (USD). A single invoice-level tax rate applies.
Can I change how the invoice looks?
Rename lines, merge them, reorder, group by task, milestone, or project, and resize the blocks. Every change saves to that invoice only.
What do I need to run it?
The TimeOS 2.0 template and a Notion account. The template uses automations, so Notion Plus or higher is required.
