Point of sale
A fast till that keeps the books for you
Scan a barcode and it's in the cart. Take cash or a QR transfer, print the receipt. Every sale is posted the moment it happens — no end-of-day merge.
- Search by name, item code, barcode or serial number
- The "Stock" tab shows which branch still has an item
- Add a new customer in one click
Inventory
Know what's left, and where
Stock is tracked per warehouse and per branch. Receive, issue and transfer with stock entries; selling reduces stock instantly.
- Stock balance by item and by warehouse
- On the app: on shelf, reserved and projected, per warehouse
Shipping & COD
Ship cash-on-delivery, reconcile without the spreadsheet squint
Create a Viettel Post shipment straight from the invoice, print the label, and let the status update itself. When the carrier's statement arrives, SellDance checks every line and flags what doesn't match.
- 14 shipment statuses, in Vietnamese
- Returns: one click restocks and issues the credit note
- Daily COD reconciliation report
E-invoices
Ring it up, and the invoice is done
Every sale issues its e-invoice from the cash register via Viettel SInvoice, and never issues it twice. The 80mm receipt carries a QR code so customers can look the invoice up themselves.
- Mistakes are fixed by replacement or adjustment — no cancellation
- Returns create the adjustment invoice automatically
Household tax
Tax books ready when the deadline is
Tax is a percentage of revenue, by business group under Decision 1233. The S1a/S2a revenue books and the 01/CNKD return take their numbers straight from your sales.
- Alerts at 80% of the threshold and when revenue passes 1 and 3 billion đồng
- Printable A4 worksheets for eTax or HTKK
