GST billing that any store can start in one minute.
Make invoices and estimates, send PDFs on WhatsApp with one tap, keep every customer, and see how your business is doing — on your phone, on your PC, and on the web, always in sync.
Free plan bills carry a small “Powered by aucstore.in” mark. Remove it with Pro — ₹599/month or ₹5,000/year.
Simple when you're busy. Powerful when you need it.
Switch between a Quick bill (name, items, done) and the Advanced screen (HSN, discounts, place of supply, shipping) with one tap.
GST done right
CGST/SGST or IGST worked out automatically from the place of supply. Tax invoice, bill of supply, or plain invoice. HSN codes suggested as you type.
WhatsApp in one tap
Every bill gets a link and a PDF. Tap WhatsApp and it opens the chat with the message ready. Email and share links too.
Customers remembered
Everyone you bill is saved with phone, address and GSTIN. Type a mobile number and the bill fills itself. Ledger and dues per customer.
Service tickets → invoice
Job cards for repairs and visits with device, problem, estimate and advance. One tap converts a ticket into a bill with the advance adjusted.
Analytics that explain
Sales trend, top items, top customers, payment modes, busy hours, GST summary — and plain-English insights about what to do next.
Inventory (Pro)
Stock goes down with every bill, low-stock alerts, stock-in and adjustments, full ledger. Works offline on Pro.
From a thermal receipt to a full GST tax invoice.
The AucStore format is free for everyone. Pro unlocks the rest — A4, A5 half-page, A6 slip, 80 mm and 58 mm rolls, letterhead and more. Your logo (transparent PNG), colours and page tint are free on every plan.

Questions stores ask us.
Is it really free?
Yes. Unlimited bills, customers and PDFs on the Free plan, forever. Free bills carry a small “Made with Auc Invoice · Powered by aucstore.in” mark; Pro removes it.
Does it work without internet?
The Free plan needs internet (your data is saved safely on our servers). Pro adds offline billing: bills are saved on the device and uploaded when you're back online.
Is my data private?
Every store's data is isolated and only visible to that store's login. We take nightly backups. Pro stores can download everything as Excel, a backup file and contacts at any time.
Can I continue my old bill numbers?
Yes — set the prefix, number of digits and the start number in Settings → Tax & numbering. Numbers restart every financial year (April).
How do I pay for Pro?
From the app: Settings → Account → Upgrade. Pay by UPI (or online checkout when enabled) and Pro activates after confirmation. You can renew in the last 7 days of your plan.
Start billing in the next minute.
Free forever. Your customers will love the WhatsApp bills.
