Background

A mechanic finishing a brake job in someone's driveway needs to hand over an invoice before the van pulls away. The options are a Word template that fights back on a phone screen, or a field-service app that wants an email address, a password, a trial, and eventually a card, in order to produce one piece of paper. So the invoice gets written by hand, or it gets written that evening, or it doesn't get written at all and the money is chased for a fortnight.

This one is ours rather than a client's, which meant we set the constraints ourselves, and the first was that nobody should have to sign up. Every other free paperwork tool in this corner of the web ranks on the word free and then asks for an account, a watermark removal, or a card. Closing that gap is most of the reason the product exists.

Challenges

• Phones first, and not as a courtesy. This paperwork gets filled in standing beside a van, one-handed, often in bad light, so the phone layout is the real design and the desktop one follows from it, rather than a desktop screen squeezed down.
• A blank form is the actual obstacle. Asking a landscaper to type out their own line items defeats the purpose, so each of the twenty trades had to open with the jobs and prices that trade bills for most often, as editable starting points rather than fixed quotes.
• Twenty trades and six papers is a hundred and twenty combinations, and a receipt and a work order are asking for different things. The dates, wording, footers, and signature lines had to change with both the paper and the trade, or the whole set reads as one template with the title swapped.
• Free, with no watermark and no cap, removes the usual way a tool like this pays for itself. It had to be cheap enough to run that the promise can hold, and designed so the free version is the whole product rather than a demo of a paid one.
• Most sole traders have no logo, and a blank where a logo should sit makes the paper look unfinished. The document had to look finished with initials alone.

Solution

JobPaperwork is one Next.js application in which the trade, not the document, is the organizing unit. Pick mechanic and the invoice opens knowing what a mechanic bills; pick catering and it changes. All six papers exist for all twenty trades, each with its own defaults and wording, and every figure is a starting point: change a rate or a quantity and the subtotal, tax, and discount recalculate as you type.

The interface is built for one hand and a phone browser, with nothing to install. Colour carries meaning conventionally and does one job each, green to proceed, red for anything destructive, and red again on an overdue paper so it reads at a glance. Business details, the logo, saved customers, and prices persist after the first paper, so the next one starts half filled in. Six document looks cover the range from a plain invoice to a shop ticket, and a business with no logo gets its initials set in the document's own type. Finished papers leave as PDFs over WhatsApp, text, or email, the three ways this work actually gets sent.

What it deliberately doesn't do is as much of the design as what it does. No Word or Excel export, no taking the payment, and nothing sent to a customer on the tradesperson's behalf. Marking a paper paid is a record, not a transaction. That keeps the product on one job, and keeps it free.

Key features

• Twenty trades, each opening with the jobs and prices that trade actually bills, from mechanic and plumbing to towing and catering
• Six papers per trade, invoice, estimate, quote, receipt, work order, and service agreement, each with its own dates, wording, footer, and signature lines
• Free with no account, no watermark on the PDF, no cap on how many you make, and no card at any point
• Business details, logo, saved customers, and prices remembered, so the next paper starts half filled in
• Six document looks, with the business's initials set automatically for the many sole traders who have no logo
• Sent as a PDF by WhatsApp, text, or email in one tap, and overdue papers turn red so they're visible at a glance

Outcome

Live today and maintained by us: a first paper takes about two minutes in a phone browser, with nothing to install and no sign-up.
