Five steps. Most stores go live in days.
Sign up at retaileros.in → add business and GST number (details auto-fill) → add every store.
Tip: Keep your GST certificate handy. It makes this step faster.
Inventory by CSV or Excel (bulk IMEI), customers and suppliers. Switching software? We migrate it.
Tip: Even a photo of a handwritten register works.
GSTIN → pre-loaded HSN codes → invoice template and logo → payment methods → scan IMEIs by brand and category.
Tip: Start with your best-selling products. You can always add more items later.
Invite staff, assign roles (sales, manager, owner), one practice bill each.
Tip: Our support team can do a free 15-minute training call with your staff.
Scan → customer → schemes → payment → invoice by print, WhatsApp or SMS.
Tip: Keep your old billing method for day one. By day two you will not need it.
