Billing Software for Water Suppliers That Actually Works in India
Volimy auto-generates GST-ready invoices from your deliveries, sends them to customers on WhatsApp, and helps you collect payments via UPI — all in one platform. No spreadsheets, no paper registers, no chasing dues at month end.
Complete Billing and Invoicing for Your Water Supply Business
Most water jar and can suppliers in India still bill customers manually — a WhatsApp message at month end, a handwritten total, or a call asking for payment. Volimy replaces all of that with a billing system built specifically for the water delivery business.
Auto Invoice Generation
Every delivery your team logs flows into the billing module. At billing time, Volimy generates a complete invoice for each customer — with product details, quantities, dates, previous dues, and net payable — without you entering a single number.
GST Calculation with HSN Codes
Add your GSTIN to your agency profile and Volimy handles tax automatically. Set GST rates per product, select tax-inclusive or tax-exclusive pricing, and get a proper tax breakup on every invoice. Fully aligned with India's GST requirements for packaged drinking water suppliers.
Branded PDF Invoices
Every invoice carries your agency name, logo, address, and GSTIN. Customers receive a professional PDF — not a screenshot or a WhatsApp note. Invoices are downloaded in seconds and stored against every customer's account.
UPI QR Code on Every Invoice
Your invoice PDF includes a UPI QR code that customers can scan and pay instantly. No back-and-forth, no cash handling confusion. Payments are reconciled against the invoice automatically once received.
WhatsApp Bulk Invoice Delivery
Select a group or all customers and send invoices in bulk via WhatsApp in one click. Customers receive the PDF directly in their WhatsApp — making it the fastest billing workflow for a water delivery service operating in India today.
Carry-Forward Dues and Partial Payments
Volimy tracks outstanding dues across billing cycles. If a customer pays part of their bill, the remaining balance carries forward to the next invoice automatically. You always have an accurate picture of who owes what.
Custom Pricing Per Customer
Running a water supply business means different rates for households, offices, and bulk buyers. Volimy supports product-wise custom pricing per customer — your invoices reflect each customer's agreed rate without any manual adjustment.
Multiple Billing Cycles
Set weekly, fortnightly, or monthly billing cycles per customer. Volimy generates invoices on schedule so you never have to remember when to bill which customer.

Whether you are an established packaged drinking water supplier or a growing RO water vendor scaling into GST, Volimy handles your tax requirements. Add your GSTIN to the agency profile, set HSN codes for each product, and toggle between tax-inclusive and tax-exclusive pricing. At the end of each month, export your GST report in PDF, Excel, or CSV and hand it directly to your accountant.
