Company and branches
MastersBranch Master
Every shop, warehouse or outlet is a branch. Each keeps its own stock, its own bill numbers and its own GST state.

Short code. Goes into every bill number, e.g. INV/HO/00042, so you can tell at a glance where a bill came from.

Users and what they can do
ToolsUser Master
Give every person their own login. A role decides what they see; branch access decides where.

Role. Admin sees everything. Manager, Cashier and Staff see less — fine-tune any role under Tools › User Rights.

Groups: the shelves your money sits on
MastersAccount Groups
MyDukan starts you with a ready chart, the way an accountant would set it up: 33 groups under Assets, Liabilities, Income and Expenses.

Groups inside groups. Fixed Assets, Bank Accounts, Sundry Debtors… all sit under Assets. Reports total them the same way.
2 · Chart of accounts · page 10
Ledgers (account heads)
MastersAccount Heads
A ledger is one account: “Shop Rent”, “HDFC Current Account”, a customer, a supplier. RK Mobiles has 1,084.

Group. Customers land in Sundry Debtors, suppliers in Sundry Creditors — made for you when you add them.

Discounts and approvals
Add-InsDiscount Limits
Let staff give discounts within a limit, and ask a manager beyond it — so no sale waits, and no discount slips through unseen.

Require approval. Turn it on; bills over the limit then wait for an approver before they can be approved.
11 · Vouchers · page 37
Receipts, payments and journals
AccountsReceipt / Payment Vouchers
- 1Receipt: money in — a customer or finance company pays a bill. Settle it against their invoices.
- 2Payment: money out — rent, salaries, a supplier's bill.
- 3Journal: no money moves — depreciation, a correction between ledgers.

Against invoice or on account. Against an invoice clears that bill; on account is money with no bill yet (an advance, a payout).
12 · GST · page 38
E-invoice and e-way bill
If your turnover needs e-invoicing, every B2B bill needs an IRN and QR code. With the GST add-on, one click on the bill gets them from the government portal and prints them.
- 1Create your API user once on the e-invoice portal (our team helps on a call).
- 2Approve the invoice → Generate IRN. The QR prints on the bill.
- 3Goods over ₹50,000 moving? Generate e-way bill from the same bill.
