Is the AI invoice generator free?

Yes, to start. The free plan makes 3 invoices and 3 quotes a month with every design and your logo, with no card and no time limit. Pro, at £9.99 a month a person, makes them unlimited.

Can the AI get the numbers wrong?

No. The AI only records what you said: who, what and how much. The VAT and the totals are worked out by ordinary code in exact pence, never by the AI.

Does it make VAT invoices?

Yes. Charge VAT at 20%, 5% or none, or say that a price already includes VAT, and the VAT lines and totals are worked out for you.

Do I need an account to try it?

No. The editor works without one, so you can write an invoice straight away. A free account saves it, downloads the PDF and keeps your customers for next time.

The AI invoice generator: say what the job was, and the invoice writes itself

DocMason turns one sentence into a proper invoice. Say who it is for, what you did and what it cost, and the lines, the VAT and the total are filled in, in a design with your logo, ready to download as a PDF. You can try it without an account.

Matt Suckling

Director, DocMason and FullDiary

Most small business invoices get written at the end of a long day: last month's Word file, a new name, a new total, and a quiet hope that the VAT is right. DocMason is an invoice and quote generator for UK sole traders and small businesses, made by Cynical Software Ltd in Perthshire, and it starts from the one thing you already know: what the job was.

How it works

Open the editor and type the job the way you would say it out loud: "Invoice John Smith 2400 for bathroom installation, due in 14 days." The customer, the line, the VAT and the total are filled in, and the invoice appears beside the chat as a real A4 page. Keep talking to change anything: add a 10% discount, move the due date, or add your bank details, which are then saved for every invoice after that.

Rather not type a sentence? Switch to the form and fill in the boxes. Both change the same invoice, so you can start one way and finish the other.

The sums are never guessed

The AI reads what you said, and that is all it does. The VAT, the discounts and the totals are worked out by ordinary code in exact pence, so £2,400 including VAT at 20% always comes out as £2,000 plus £400 VAT. Say whether a price includes VAT, choose 20%, 5% or no VAT, and the VAT lines follow.

Make it look like yours

Pick from 26 designs and add your logo, and your colour and font follow you from one design to the next. Invoice numbers start at INV-1001 and count up on their own; set your own, or hide the number if you do not use one. Your business details and your bank details go on every invoice, so the customer knows exactly how to pay.

On the free plan, invoices carry a small Generated with DocMason.Ai line at the foot. Pro takes it off.

Getting paid

Download the PDF and send it however you like. On Pro you can send it straight from DocMason as a link the customer opens on any phone, with a button to pay by card through your own Stripe account. QuoteChaser, also on Pro, follows up an unpaid invoice for you, politely and in your name, the day after it falls due and again a week later, and stops the moment it is paid.

Quotes work the same way

Type "Quote Sarah Pearce 850 for new fencing, plus VAT" and you have a quote. On Pro the customer can accept it online with one tap, and an accepted quote becomes an invoice in one click, with the same lines, the same design and the next number.

If you take bookings

DocMason's booking system, FullDiary, uses the same invoices. A finished appointment becomes an invoice in one click, with the customer, the service and the price already filled in.

A finished booking turned into an invoice, with nothing typed twice.

What it costs

The free plan covers 3 invoices and 3 quotes a month, with every design and your logo, and needs no card. Pro makes invoices and quotes unlimited and adds sending by email, online acceptance, QuoteChaser and card payments, for £9.99 a month a person, never more than £39.99.
