Talk to usA day with Invoay
You run the shop. We handle the numbers.
You didn't open a shop to sit with registers and spreadsheets. You opened it for your customers, your family and your own name on the board. Here's how a normal day feels when Invoay takes care of the rest.
Shutter up, phone in hand
Invoay Pocket already shows yesterday's sales, cash and what's running low. Before the first customer, you know exactly where you stand.
The rush, without the stress
Five customers at the counter. Scan, UPI, bill on WhatsApp — each one done in seconds. Nobody waits, nobody gets the wrong change.
"The same shampoo as last time?"
A regular walks in. Type her number and you see what she bought last time, her points and her birthday next week. She feels remembered.
Stock alert, not a stock-out
Invoay flags your best-seller is down to 6 pieces. The purchase order to your supplier is ready in one tap.
Home on time, for once
Day-end closes itself — cash, UPI and card already matched. You check the total on your phone at dinner, not at the counter at midnight.

Watch a bill being made in under 30 seconds
SimplePOS runs on Android POS machines, Windows billing PCs and iPad. Here's a real apparel bill, live — scan, pick the customer, the offer applies itself, take UPI, and the bill goes on WhatsApp.

Built for how India shops
Made for Indian counters, not adapted for them
The small things that matter at an Indian store — customer credit, MRP, loose items, festival rush, a customer's mobile number as their ID — are built in from day one.
Customer credit with reminders
Credit per customer with due dates, partial payments and polite WhatsApp reminders. No more paper diary.
No cards, no apps to download
Customers just share their number. Points, wallet and history come up instantly.
Loose items & weighing scales
Sell flour, pulses, sweets or dry fruits by weight with scale integration and price-per-kg labels.
MRP, schemes & combos
MRP vs selling price on the bill, buy-2-get-1, combos and "you saved ₹X" for the customer.
Different rates for B2B buyers
Retail, wholesale and dealer price lists, with the buyer's GSTIN on B2B invoices.
Print your own barcodes
Garments, loose stock and local brands get barcode labels, so billing stays fast.
Cloud backup, always
Bills and stock live in the cloud. A crashed PC or a lost phone doesn't mean lost data.
Support in your language
Training and support on call and WhatsApp in English and Hindi, 10 AM – 7 PM.

When the cashier saves the bill on SimplePOS, the GST invoice is sent from your business number on the official WhatsApp Business API through Wabixo, with points earned and balance.
What can Invoay AI do for my shop?
Invoay AI gives you a daily summary, suggests what to reorder, finds customers who stopped visiting and drafts WhatsApp offers. With Wabixo, an AI agent answers customer questions on WhatsApp 24×7. It works only on your shop's own data.
