Create a Sales Invoice

A Sales Invoice is the formal bill you give to a customer when you sell goods or services. It records what was sold, at what price, with applicable taxes (GST), and the payment received. Creating a sales invoice automatically reduces your stock for the sold items, updates the customer's outstanding balance, and contributes to your sales and profit reports. Stock Register supports GST and non-GST invoices, multiple payment modes, item-level and bill-level discounts, shipping and additional charges, multiple invoice formats (A4, A5, thermal), and instant sharing via WhatsApp or PDF. This is the most commonly used feature in Stock Register — retailers, wholesalers, and service providers use it daily.

Steps

  1. Navigate to Sales > Sales Invoice from the sidebar.
  2. Click "+ Create Sales" button to open the invoice form.
  3. Select or add a Party (Customer) — you can add a new customer on the fly if they don't exist yet.
  4. Set the Invoice Date (defaults to today) and Invoice Number (auto-generated, editable).
  5. Select the Store if you have multiple stores/godowns — the invoice will deduct stock from this store.
  6. Add items by clicking "+ Add Item" — search by item name or scan a barcode. You can add multiple items to a single invoice.
  7. For each item, enter Quantity, Price, and Unit. If secondary units are configured, you can switch between units.
  8. Apply Item-level Discount for individual items — supports both percentage (%) and flat amount (Rs.) discounts.
  9. GST/Tax is auto-calculated based on each item's tax rate settings. CGST and SGST (or IGST) are computed automatically. HSN codes are included if configured.
  10. Add Extra Discount (bill-level discount) to apply an overall discount on the invoice total — supports both percentage and amount.
  11. Add Shipping Charges or any other additional charges if applicable.
  12. Choose Payment Mode: Cash, Credit (pay later), Bank Transfer, UPI, or Cheque.
  13. Enter Payment Amount — you can record a partial payment or full payment. If partial, the remaining balance is tracked as outstanding against the customer.
  14. Add optional Remarks or notes for internal reference.
  15. Click "Save" to create the invoice. Stock is automatically deducted and customer balance is updated.
  16. Use "Share" to send the invoice via WhatsApp or download as a professional PDF. You can also Print directly on A4, A5, or thermal printers.

Tip: You can convert a Quotation or Sales Order directly into a Sales Invoice without re-entering item details. All items, quantities, prices, and discounts carry over automatically.

Common Questions

Yes, Stock Register supports both. If GST is enabled for your business and items have GST rates configured, tax is auto-applied on invoices. For non-GST invoices, simply keep GST disabled or set item tax rate to 0%. You can mix both in the same business.

After creating an invoice, click the 'Share' button. You can send it directly via WhatsApp, download it as a professional PDF, or share the invoice URL. The invoice includes your business logo, brand colors, digital signature (if configured), business details, and all item/tax information.

Stock Register supports Cash, Credit (pay later), Bank Transfer, UPI, and Cheque as payment modes. You can set a default payment mode in Entry Settings (Settings > Entry Settings). You can also record partial payments during invoice creation — the remaining amount is tracked as the customer's outstanding balance.

There are two levels of discounts: Item-level discount is applied per item and can be set as a percentage (%) or flat amount (Rs.). Bill-level discount (Extra Discount) is applied on the overall invoice total after all items and taxes. Both types can be used together on the same invoice.

Stock Register supports multiple invoice themes and formats. You can print on A4 paper, A5 paper, or thermal printers (POS receipt printers). You can customize the invoice with your business logo, brand colors, digital signature, slogans, and terms & conditions from Settings > Bill Settings. Bill copy types include Original, Duplicate, and Triplicate.

Yes, when you save a sales invoice, the stock quantity for each item is automatically reduced from the selected store. You do not need to make a separate stock adjustment. If you have multiple stores, stock is deducted from the store selected on the invoice.

Yes. Open the Quotation or Sales Order and click 'Convert to Invoice'. All item details, quantities, prices, and discounts are carried over automatically to the new sales invoice. This eliminates double entry and ensures consistency. The workflow is: Quotation → Sales Order → Sales Invoice, but you can skip the Sales Order step and convert directly from Quotation to Invoice.
