About this app

Simple Invoice & Estimate is an invoice maker and estimate maker for contractors, freelancers and small businesses. Send a professional, branded PDF invoice in under two minutes — no account, no sign-up, no internet required.

Add your logo once and every estimate and invoice you send is a polished PDF with your branding, your tax rate and your numbering.

INVOICE MAKER
• Line items with quantity × rate — totals and tax calculated for you
• Set your tax once: HST, GST, VAT, sales tax, any name and any rate
• Discounts, notes and payment terms
• Automatic invoice numbering (INV-0001, or your own prefix)

ESTIMATE MAKER
• Unlimited free estimates and quotes
• Track sent, accepted and declined
• One tap converts an accepted estimate into an invoice — nothing retyped

GET PAID AND STAY ORGANISED
• Mark invoices paid or unpaid and spot overdue at a glance
• A clean PAID stamp on settled invoices
• Search everything by client or invoice number
• A reusable client list, so repeat customers take one tap

BRANDED PDF EXPORT
Your logo and business details on every document. Share by email, WhatsApp, text or any app, or save the PDF. A crisp, professional layout that looks right printed or on a phone.

WORKS OFFLINE, FROM THE JOB SITE
Invoice from the driveway before you leave. Everything runs on your phone with no connection, no account and no ads. Your data stays on your device.

MADE FOR
• Contractors, handymen, landscapers, cleaners and mobile mechanics who invoice on site
• Freelancers and consultants who want a simple invoice app, not accounting software
• Small shops and side businesses that need a quote maker and a receipt in the same place

FREE PLAN, HONEST UPGRADE
Create up to three invoices a month free, with unlimited estimates. Unlimited invoices and extra PDF templates are a simple subscription that supports an independent developer.

Simple Invoice & Estimate is made by Next Layer Technologies, an independent studio in Ontario, Canada. Need customers, jobs and scheduling too? Try our companion app, Simple CRM for Contractors. Learn more at nextlayertechnology.net/simple-invoice or write to [e-mail].
