Invoicer
A fast invoice on the fly.
Invoicer is an offline invoice app for one-man tradesmen — a fast invoice on the fly, emailable as a clean PDF. The carbon pad, without the carbon. No account, no subscription, works with no internet.
What it does
- Build an invoice fast — add the job's line items with a big numeric keypad, right from the truck.
- Save your clients — pick a client again without retyping their details.
- Set your details once — your business info, rate, and tax are entered once and reused.
- Your logo on top — add your own logo so the invoice looks like yours.
- A clean PDF — every invoice becomes a tidy white-paper PDF you can email, message, print, or save.
- Numbering handled — invoice numbers are kept in order for you.
- Money kept exact — totals and tax are calculated precisely, never rounded oddly.
- All on your device — clients and invoices are stored locally, nothing in the cloud.
What it is, and what it isn't
Invoicer does one job well: a clean, professional invoice made and sent in a minute, by the one person who does the work and the billing. The invoice your customer receives is plain white paper with black text — never the dark app theme.
- Not accounting software. It writes invoices; it doesn't keep your books, track expenses, or do your taxes.
- Not in the cloud. Your clients and invoices live on your device.
- No account, nothing tracked. No login, no analytics, no third-party scripts.
- Nothing to back up to a service. You keep the PDFs you send — they're your records.

Questions
Does it work offline?
Yes. After the first load it never needs the internet.
Is there a subscription?
No. There is no subscription and no recurring fee.
Do I need an account?
No. There is nothing to sign into.
Is my data private?
Yes. Your clients and invoices stay on your device. Nothing is uploaded.
What does it run on?
Any modern phone, tablet, or computer browser — and it installs to the home screen.
How does my customer actually get the invoice?
Invoicer turns the invoice into a clean white-paper PDF on your phone and hands it to whatever you already use — email, text, print, or save. There's no portal and nothing for your customer to sign up for; they simply receive the invoice.
Will it help at tax time?
Invoicer keeps every invoice you've written, and you keep every PDF you send — that's your paper trail. It deliberately isn't bookkeeping or accounting software: no expenses, no ledgers, no tax filing. At tax time you or your bookkeeper work from the saved invoices, same as the old carbon pad.
Can customers pay me through the app?
No — Invoicer has no payment processing and never connects to your bank. You collect the way you already do (cash, check, or bank transfer), and the invoice carries your payment terms; Invoicer just makes the paperwork fast.
