Quick answer: To send a professional invoice from your phone in under 2 minutes, first do a one-time setup in an invoice maker app (business profile, logo, template, and payment details). After that, each invoice is quick: choose the client, add your items, check the total, then export a PDF and share it by email or a messaging app. Most of the work happens once; every invoice after that takes just a few taps.
Introduction
You've just finished a job. Your client is right there, happy with the work. This is the best possible moment to send your invoice, but your laptop is at home and your template is buried in a folder somewhere.
With the right app on your phone, none of that matters. You can create a clean, branded invoice and send it before you've even packed up.
The secret to doing it in under two minutes isn't typing fast. It's setting things up once so that each invoice only needs the details that change. This guide shows you exactly how, with a timed walkthrough, a one-time setup checklist, and copy-and-paste messages for sending your invoice.
Why Speed Matters When You Invoice
Sending an invoice quickly isn't just convenient. It affects how fast you get paid:
- The payment clock starts sooner. Your due date is counted from when the client receives the invoice.
- The work is still fresh. Clients approve invoices faster when they've just seen the results.
- You don't forget details. Extra hours or materials are easy to miss if you invoice days later.
- Admin doesn't pile up. No more evenings spent catching up on invoices.

Before You Start: The 10-Minute One-Time Setup
This is what makes two-minute invoices possible. Do it once, and you'll never repeat it.

- Add your logo.
- Pick a template and add your signature or stamp with Custom Templates.
- Add your payment details, such as bank account information.
- Set your default terms, for example "Due within 14 days."
- Add your regular clients so you can select them later.

The 2-Minute Invoice: A Timed Walkthrough
Once your setup is done, here's how a typical invoice comes together.
0:00–0:15: Start a new invoice
Open the app and tap to create a new invoice. Your business details, logo, template, and payment terms are already filled in.
0:15–0:30: Choose the client
Select the client from your saved list. If they're new, add their name, email, and billing address. They'll be saved in Client Management for next time.
0:30–1:15: Add your items
Add each product or service with a short description, quantity, and price. The app calculates line totals and the invoice total automatically. Add any taxes or discounts that apply.
Tip: be specific. "Bathroom tap replacement, parts and labor" is clearer than "Plumbing work," and clear invoices get paid faster.

1:15–1:30: Check the essentials
Take a few seconds to check:
- Client name and email
- Items and total
- Due date
- Currency (if the client is abroad, use Multiple Currency Support)
1:30–2:00: Export and send
Export the invoice as a PDF and share it using your phone's usual sharing options, such as email or a messaging app your client uses. Done.
