Quoting and invoicing app for trades

Quoting and Invoicing Software for Contractors and Trades

Build the quote while you are still at the customer’s place: pick items from your own price list, let the app handle discounts and HST, and have the customer sign on your phone. An accepted quote becomes an invoice in one click, and one screen shows who still owes you money.

What the app does

Quotes from your price list in minutes

Labour, materials, equipment and flat rates live in the price list - pick items, adjust quantities and see subtotal, tax and total instantly.

PDFs that look professional

Letterhead with logo, company and customer details, line items, payment terms and banking info - ready to email or print.

Customer signs on site

The customer signs on your phone or tablet. The quote switches to accepted and the signature appears on the PDF.

Job site photos

Take photos before you start; they stay attached to the quote, so there is no argument later about what was agreed.

Quote to invoice in one click

An accepted quote becomes an invoice with the same items. Track paid, unpaid and overdue, with a ready-made reminder text.

Works without signal

In a basement or on a new build with no reception, the app keeps working and syncs as soon as your phone reconnects.

A list of screens and features, a deadline and a price before work starts.

A new version every week

FAQ

Pricing is on request - send a short description and you get a proposal. The final price depends on the number of users, document design and extras such as accounting export or online payments. You get a fixed quote before any work starts.

Hosting, database and backups for a typical app run €20-60 per month; larger setups with many users and lots of photos €60-150. Changes and new features are billed by agreement - hourly or as a monthly plan.

Yes. The app installs on your phone and works without signal - write the quote, take photos, get the signature. Everything syncs once you are back online.

You do. At the end of the project you get the source code and a full data export. You are not tied to me or to a particular host.

Usually 5-7 weeks. You get a new version to try every week, so you can send your first real quotes after two or three weeks.

Of course. Many start with quotes and the price list only and add invoicing, accounting export or scheduling later. The app is built to grow with your business.
