How to Send an Invoice From Your Phone in 10 Seconds

You have just finished a job. You are in the van, heading to the next one. The last thing you want to do is sit down at a laptop tonight and fill in an invoicing form.

So you tell yourself "I'll do it later." Later becomes tomorrow. Tomorrow becomes next week. And by then, the customer has forgotten about it too.

The average UK tradesman is owed £8,500 in unpaid invoices at any time. A big chunk of that is invoices that were never sent — or sent so late that the urgency was gone.

The Problem: Invoicing Takes Too Long

Traditional invoicing apps need you to open an app, find the client, fill in the line items, set payment terms, preview it, and hit send. That is 5-10 minutes per invoice — fine if you are at a desk, painful if you are between jobs.

Most tradespeople do 3-5 jobs per day. That is 15-50 minutes of invoicing admin every evening. No wonder it gets put off.

The Solution: Just Say It

With mNudge, invoicing is as easy as sending a WhatsApp message. Here is what it actually looks like:

That is it. Ten seconds, from the van, between jobs.

Voice Notes Work Too

Typing on a phone can be fiddly — especially with dirty hands. mNudge accepts voice notes. Just say what the job was:

mNudge transcribes it, creates a professional PDF invoice with your business name and payment link, and sends it to the client on WhatsApp. The client taps one button to pay via bank transfer.

What You Get

• Professional PDF invoice with your business name, auto-numbered, payment terms included
• One-tap payment link — your client pays via Open Banking, money in your account in seconds
• Read receipts — you know when the invoice is delivered and read
• Automatic chasing — if they do not pay, mNudge sends polite reminders over 21 days

No App to Download

mNudge works entirely inside WhatsApp. You already have it on your phone. No account to create, no forms to fill in, no new app to learn. Set up takes 90 seconds — your name, your trade, your business name. That is it.
