Day 1: company and people
Enter your company and tax details. Create locations (shop, warehouse). Create users and give each a role: cashier, storekeeper, accountant, owner. Decide who can see cost prices.
Day 2: items
Import your item list from Excel: the wizard maps your columns, checks every row and imports all or nothing. Decide per item whether it is serial-tracked or held as a quantity.
Day 3: opening stock
Receive opening stock with barcodes. Print labels for units that have none.
Day 4: customers and balances
Add customers and their credit limits. Enter opening balances owed to and by you.
Day 5: a practice sale
Make a sale, a return and a payment at the counter. Check the invoice, the stock movement and the ledger entry. Then go live.
