Frequently Asked Questions
What should be included on a plumber invoice?
A professional plumber invoice must include your business details, license number, customer contact info, itemized materials, labor hours or flat rates, subtotal, taxes, and clear payment terms.
Can I send this plumber invoice via WhatsApp?
Yes. With the Invoice for Trades mobile app, you can export a crisp PDF invoice and share it directly via WhatsApp, SMS, or email in under 2 minutes.
Is it better to use an Excel/Word template or a mobile invoice app?
Excel and Word templates break formatting on phones, require a desktop computer in the evening, and don't track paid vs unpaid invoices. A mobile app lets you bill on site in 90 seconds and works 100% offline.
Does the app work without internet on the job site?
Yes. Invoice for Trades operates 100% offline. You can create quotes and invoices in basements or rural areas without mobile data.
