the honest comparison
Vyapar is India's leading GST billing software. ExtinctBook is a focused udhar khata. They solve different problems. Here's how to know which one your shop needs — or if you need both.

The clearest signal: if a customer asks you to hold ₹500 on credit while buying groceries, which app do you open? For ExtinctBook users, it's four taps. For Vyapar users, it requires navigating the invoice flow — which is designed for billing, not quick counter entries.

where it matters
the speed difference
ExtinctBook: tap customer → amount → credit → confirm. Done in 4 seconds. Vyapar's entry flow is built around formal billing — customer, items, quantities, tax rates. Fine for an invoice, slow for a counter entry during a queue.
the reminder difference
ExtinctBook sends a WhatsApp reminder with an embedded payment link. The customer taps and pays directly. Vyapar doesn't offer WhatsApp reminders with payment links — you'll need to follow up manually or use a separate tool.
the price difference
ExtinctBook's full khata — unlimited customers, unlimited entries, WhatsApp reminders — is free. Vyapar's free tier is limited; the features most shops actually need (desktop, GST reports, full inventory) require a paid annual plan.

The both-tools option
Many shops need both. Use ExtinctBook for quick counter-side udhar with regular customers. Use Vyapar for GST invoicing with wholesale or business accounts. The two apps don't overlap in daily use.

before you decide
Vyapar is primarily a GST billing and accounting software. It handles invoices, GSTR reports, inventory, and purchase orders. It has a ledger module, but it is not designed for quick counter-side udhar entries. If you need to record that Ramesh took ₹240 of groceries during a rush, ExtinctBook is the right tool. If you need to issue a GST invoice to a business customer, Vyapar is the right tool.
Yes, and many shops do. Use ExtinctBook for counter-side udhar tracking with regular credit customers. Use Vyapar for GST invoicing with wholesale buyers or business accounts. They solve different problems and don't overlap in the day-to-day.
Vyapar has a limited free tier. Most useful features — desktop access, multi-device sync, GST reports, full inventory — require a paid plan starting around ₹1,999/year. ExtinctBook's core khata (unlimited customers, unlimited entries, WhatsApp reminders with payment links) is completely free.
Vyapar can send payment reminders, but WhatsApp reminders with embedded payment links are not a core feature. ExtinctBook's reminders include a direct payment link so the customer can pay from the message in one tap.
