GST Billing & Invoicing with Tally Integration
GST-ready invoices in 30 seconds. Share them on WhatsApp, get paid faster, and keep your CA happy.
Dreamwell Billing & Invoicing is a GST billing system built for Tamil Nadu SMEs. It creates GST-compliant invoices with GSTIN, HSN/SAC and the right CGST/SGST or IGST split, sends them on WhatsApp with a payment link, tracks who has paid, and sends polite reminders automatically. It works alongside Tally, after a quick compatibility check, so your accountant keeps working the way they already do.
Quick answer
Dreamwell Billing & Invoicing creates GST-ready invoices with GSTIN, HSN/SAC and the right tax split, sends them on WhatsApp with a payment link, and chases unpaid bills automatically. It costs ₹15,000–₹30,000 one-time plus ₹3,000 GST setup (excl. 18% GST), with no monthly fee. See our GST billing checklist.
What problem does this solve?
Most SME owners we speak to lose hours every month to billing:
- • Typing invoices in Excel or Word, then re-entering the same data into Tally
- • Getting the CGST/SGST vs IGST split wrong on inter-state sales
- • Looking up HSN codes and rates again after GST rate changes
- • Forgetting to follow up on unpaid invoices, so cash stays stuck with customers
- • Sending a pile of bills to the CA at month-end, then fixing mismatches before GSTR-1
Dreamwell Billing fixes the daily part (invoices, payments, reminders) and hands clean data to your accounting system for filing.
Key Features
GST-ready invoices
Auto-fills GSTIN, HSN/SAC, place of supply and the CGST+SGST or IGST split — fewer errors, cleaner input tax credit for your buyers.
Current GST rates
Set the right rate per item: 5%, 18%, the 40% de-merit rate, or special rates where they apply. Stays correct after rate rationalisation.
30-second invoicing
Pick customer, pick items, enter quantity, done — on phone or computer. Bill right after the sale, not at month-end.
WhatsApp invoicing
Send the invoice PDF and a payment link to your customer's WhatsApp in one tap. Customers open WhatsApp; email often goes unread.
Payment tracking
Paid, partly paid, unpaid and overdue at a glance. Know exactly who owes you what.
Automatic payment reminders
Scheduled, polite WhatsApp reminders for overdue invoices — better cash flow without awkward calls.
Client management
Customer database with GSTIN, addresses and billing history. No more searching old bills.
Revenue & GST reports
Monthly and yearly sales, tax collected and top customers, plus exports your CA can use for GSTR-1 / GSTR-3B.
Print, PDF & data import
Print or download invoices in your format with logo, and import customers and items from Excel during setup.
How It Works
Free consultation
15 minutes on WhatsApp: how you bill today, which accounting software you or your CA use, and your invoice volume.
Setup & Tally check
We configure GSTIN, bank/UPI details, invoice format and logo, import customers and items from Excel, and run the Tally compatibility check.
Training & go-live
One training session for you and your staff. Go-live is typically within 2 business days after prerequisites are ready.
Who It's For
A good fit if you raise roughly 50 or more invoices a month, use Tally (or a CA who does), and your customers already talk to you on WhatsApp. It may be overkill if you raise only a handful of invoices a month — a free basic tool might do.
Tally, Zoho Books and Busy integration
Most Tamil Nadu SMEs, or their CAs, already use Tally. We don't ask you to replace it. Dreamwell Billing handles fast daily invoicing, WhatsApp sharing and payment follow-ups; your accounting software stays the system for books and final GST filing.
| Accounting software | How it connects | Status |
|---|---|---|
| Tally (TallyPrime / Tally.ERP 9) | Sales vouchers, ledgers and item data shared with Tally | Supported after a compatibility check of your Tally version and setup |
| Zoho Books | Export of invoices and customer data in an import-friendly format | Confirmed case-by-case during consultation |
| Busy | Export of sales data for your CA's Busy workflow | Confirmed case-by-case during consultation |
What the compatibility check covers: your Tally version, how your ledgers and stock items are named, whether your CA works on the same data file, and how often data should flow (daily or month-end). If something doesn't fit cleanly, we tell you before you pay for anything extra. Read more: Automate GST billing without changing your software.
Works even better with the WhatsApp AI bot
Pair Billing with our WhatsApp AI Assistant. Customer orders come in on WhatsApp, an invoice is generated, the PDF and payment link go back on the same chat, and reminders go out automatically if payment is late. The Combined Package (₹36,000–₹72,000 one-time, excl. 18% GST) includes a 10% bundle discount — see pricing.
