The Procurement Lifecycle
Purchasing follows a structured accounting workflow:


Recording a Purchase Invoice (Stock Merchandise)
Navigate to Accounting > Purchase Invoices > New Purchase Invoice (or press Ctrl+K and type New Purchase Invoice).
1. Supplier & Reference Numbers
- Select the Supplier.
- Enter the vendor's physical paper invoice number in the Supplier Invoice # field for reconciliation.
2. Line Items, Batches & Serial Tracking
- Select items from your catalog.
- If items have batch or serial tracking enabled, specify batch lot expiry dates or serial codes per row:


3. Direct Supplier Payment & Auto Goods Receipt Toggles
Roznamcha Digital can automate immediate payment disbursement and warehouse stock receipt at the moment of invoice submission:
- Include Payment Toggle (Cash Purchase): Automatically creates and submits a
Paymentvoucher from your selected cash drawer or bank ledger upon purchase bill submission. - Auto Stock Transfer Toggle (Instant Goods Receipt): When checked, automatically generates and submits a
Purchase Receiptstock voucher into your default warehouse (Defaults > Purchase Receipt Location), updating stock balances in real time.

Booking Direct Overhead & Operating Expenses
Not all vendor bills are for resalable inventory. To record operating expenses like Office Rent, Electricity Bills, or Consulting Fees:
Steps to Book an Expense:
- Create a Purchase Invoice with the service provider as the Supplier (e.g., Islamabad Electric Supply Co. or Commercial Plaza Landlord).
- Select an expense item (e.g.,
Electricity BillorMonthly Office Rentwhere Maintain Stock is unchecked). - The invoice automatically debits the designated Expense Ledger Account without altering warehouse inventory.
Purchase Returns & Debit Notes
If goods arrive damaged, expired, or defective, you return them to the vendor and issue a Debit Note:
1. Creating a Debit Note:
Open the original submitted purchase invoice, click the Actions Menu (three dots), and click Create Return:

Roznamcha Digital creates a new Purchase Invoice in Debit Note / Return mode:

Submitting the Debit Note reduces your Accounts Payable debt and removes the stock value:

Common Pitfalls & Best Practices
Do Not Forget the Supplier Invoice Number: Always enter the supplier's physical bill number in the Supplier Invoice # field. When matching monthly vendor statements, this is the quickest way to resolve balance discrepancies.
Match Received Quantities with Purchase Receipts: If your warehouse receives shipments before accounting receives the bill, use the Purchase Receipt (GRN) module first, then link it to the purchase invoice.
