Zundaro QuoteDesk: Quote & Invoice App for Service Businesses (English/Spanish)

Create professional quotes, invoices and receipts for your service business — in English or Spanish. Zundaro QuoteDesk is a simple app that comes as one file: no account, no subscription, and it works offline.

What you can do

• Build quotes with your client details, services, quantities and prices
• Turn a quote into an invoice in one click, and make payment receipts
• Add your business name, logo and payment methods once
• Save your services and prices in My prices and reuse them in every quote
• See a private profit check (estimated cost, profit and margin) on every job — your client never sees it
• Switch the app between English and Spanish, and print each document in either language
• Print or save any document as PDF, or download the PDF and send it by WhatsApp or email
• Back up your work to a file and move it to another device

How it works

1. Download and unzip the file after purchase.
2. Double-click Zundaro-QuoteDesk.html. It opens in your web browser (Chrome, Edge, Safari or Firefox) and works right away, even without internet.
3. Set up your business and prices, then create your first quote.

What's included

• Zundaro-QuoteDesk.html — the app
• Quick-start guide (PDF, English & Spanish)

Good to know

• Your business details and prices are saved in the browser on your device. Always open the app with the same browser, and save a backup file now and then.
• Works best on a computer. On Android, open the file with Chrome. Not tested on iPhone/iPad.
• Single-business license: please don't resell or share the file.
• Organizational tool — not legal, tax or accounting advice.
