Bill clients for construction and civil work professionally — milestone invoices, labour + materials, GST-compliant — all from your phone.
Common Problems
Milestone billing across long projects is complex
A 6-month construction project may have 4–5 billing stages. Tracking what's been billed, what's been paid, and what's outstanding is difficult without a proper system.
Clients need proper GST invoices for their books
Builders, developers, and corporate clients need GST invoices with your GSTIN, works contract SAC code, and correct tax breakdown for their accounting and ITC claims.
Getting paid on time on construction projects is hard
Delayed payment is endemic in construction. A professional invoice with a clear due date and UPI payment option puts you in a stronger position.
You're on-site, not in an office
You need invoicing that works on a phone, in the field, without needing a laptop or accountant present.
