A quotation and invoice tool with templates, approvals, VAT and GST handling, PDF export, payment links and reminders. Custom software development from $800 to $1,800 in 7 to 14 days.
The problem
Contractors, agencies, suppliers and service companies in the UAE and India still build quotes in Word, track them in a spreadsheet and retype the accepted ones into an invoice. Quotes go out with the wrong VAT or GST rate, nobody follows up after a week, and the accounts team spends Friday afternoons chasing payments by WhatsApp. Generic invoicing apps do not handle approval steps, multi-currency or your product catalogue.
What we build
We build a quotation and invoicing tool around your catalogue and pricing rules: branded quote templates, optional items and discounts, internal approval, e-signature acceptance, one-click conversion to invoice with UAE VAT or Indian GST, PDF generation, Razorpay or Stripe payment links and automatic reminders on WhatsApp and email. Claude Code and Cursor scaffold the document models, numbering and tax logic quickly, DeepSeek generates hundreds of test invoices to check totals cheaply, and we hand-verify tax rounding against your accountant's samples. Full source code and a fixed price that never exceeds $2,500.
