The store's catalogue, orders, payment and customers are managed here.
Amount fields read what you type as Toman
On a site whose currency is Rial, every amount field — product price, coupon amount, shipping cost — deliberately takes Toman and multiplies by 10 itself, because sellers think in Toman.
So typing a Rial figure straight in records ten times the intended amount. The hint under the field always shows the real stored value; a glance at it before saving catches this.
An order with a total never completes free
If an order has an amount and no payment gateway is enabled, the order is refused and marked failed — it is never quietly treated as paid.
Genuinely free orders and the Direct Payment method (bank transfer confirmed by hand) are the exceptions.
How the sections fit together
Products is what you sell. Categories and Attributes are how it is organised and chosen. Orders is where a sale actually happens, and where stock and access are applied. Tax & Shipping and Settings are the rules that run at checkout.
