Run your freelance business from a single file — no app, no account, no monthly fee, and none of your client data ever leaves your computer.
Hours in a spreadsheet, invoices in a separate app, clients in your email — nothing is connected, and the cracks start to show when work picks up.
Every billing cycle you copy hours into an invoice manually. If a rate changes or a project runs over, you recalculate everything by hand — and mistakes slip through.
You track invoice numbers in your head or by scrolling through sent emails. With multiple clients and series, it's only a matter of time before you issue two invoices with the same number.
The invoicing app you subscribe to charges you every month, stores your client data on someone else's server, and adds features you'll never use. A well-built HTML file does the same job without any of that.
Clients, projects, time tracking, and invoicing — all in one private file.
From the first client contact to the last paid invoice — everything in one file, without a single account or subscription.
Store complete billing data for each client — legal name, tax ID, address, contact details, and currency. Everything you need to generate a correct invoice is already there when you need it.
Track each project with its agreed budget, contracted hours, and hourly rate. Know at a glance which projects are within scope and which ones have exceeded the original agreement.
Log billable hours against any project. The client's rate is applied automatically — no manual calculation. When it's time to invoice, the hours are already there and ready to convert.
Generate real invoices with automatic consecutive numbering, configurable taxes, and withholdings. Up to 3 independent series for different clients or billing scenarios. Supports corrective and recurring invoices.
A real-time summary of what's been collected, what's still pending, and which projects have gone over the agreed hours. Everything that matters about your business, visible at a glance.
No app to install, no account to create, no subscription to maintain. A file that handles the real-world complexity of freelance invoicing.
Select logged hours from Time Tracking and they flow directly into the invoice — no copy-pasting, no manual rate calculation. The math is done for you.
Manage separate numbering for different billing scenarios — one for regular clients, one for international work, one for a secondary brand. Each series maintains its own consecutive counter.
Configure any local tax at the rate that applies to your business. Set it per client or per invoice — works whether you operate in Spain, the UK, Mexico, or anywhere else.
Issued an invoice with an error? Generate a corrective invoice linked to the original, with the correct number format and a reference to the invoice being corrected.
Set up repeating invoices for retainer clients so you don't have to recreate them from scratch each billing cycle. Define the amount, period, and client.
Export a full backup of all your clients, projects, hours, and invoices as a JSON file. Restore it at any time from the same or a different device.
A step-by-step guide included inside the tool — how to configure clients, set up invoice series, apply taxes, and issue your first invoice correctly from day one.
