A Credit Note is an official financial document indicating that the company has reduced a customer's debt or created credit in their favor. In the AF Code accounting database, this document is implemented as the CreditNote entity and is a core component of the Accounts Receivable module.

In the AF Code accounting software, Credit Notes are managed alongside invoices, payments, payment allocations, and Aging reports. For businesses operating in Afghanistan, using Credit Notes for post-sale discounts, correcting erroneous invoices, and managing product returns is crucial. AF Code Company has designed this feature considering the specific needs of the Afghanistan market.

In the AF Code accounting database, each Credit Note is stored with this information:

• Related Customer (CustomerId): Relationship with the Customer entity
• Original Invoice (InvoiceId): Optional - the invoice this note relates to
• Credit Note Number (CreditNoteNumber): Unique document identifier
• Issue Date (IssueDate): Official document date
• Document Status (Status): Draft, Issued, Paid, Void
• Total Amount (TotalAmount): Total amount of the Credit Note
• Remaining Amount (RemainingAmount): Amount still available for application to invoices

This structure is integrated with other modules in the AF Code accounting software, and all relationships in the accounting database are designed with referential integrity.

In the AF Code accounting software, Credit Notes have critical applications:

• Correcting invoice errors: If an invoice was issued with an incorrect amount, instead of direct editing (which is not allowed for issued documents), a Credit Note can reverse the excess amount.
• Post-issuance discounts: Sometimes after issuing an invoice, a new discount agreement is reached with the customer. A Credit Note legally registers this discount in the accounting database.
• Product/Service returns: When goods are returned to inventory, a Credit Note reflects the financial impact in the accounts.
• Customer balance transparency: With accurate recording of Credit Notes, customer balances remain transparent and traceable at all times.

For AF Code Company operating in Afghanistan, this transparency is vital for cash flow management and accurate financial reporting.

1. Create

In the creation stage:

• The document date must be within an open fiscal period
• The customer must be valid and active
• If an original invoice is specified, it must belong to the same customer and not be voided
• The Credit Note is created with Draft status and a temporary number
• The Remaining Amount is set equal to the total amount

This logic is implemented in the AF Code Company's AR service and stored in the accounting database.

2. Update

Editing is only allowed in Draft status. Once the document is issued, it cannot be freely modified. After editing, the remaining amount is recalculated and adjusted.

3. Post

When a Credit Note moves from Draft to Issued status:

• The document becomes official and usable in subsequent operations
• If it has an original invoice with an open balance, the system automatically applies part of the credit to that invoice

This behavior is very useful for quick customer account reconciliation in the AF Code accounting software.

4. Apply to Invoice

After issuance, the Credit Note can be applied to a customer invoice, subject to several important conditions:

• The Credit Note must be Issued
• The invoice must belong to the same customer
• The invoice must not be Void
• The applied amount must not exceed the Credit Note's remaining amount or the invoice's balance

After application, the Credit Note's remaining amount decreases, and the invoice's PaidAmount and Balance are updated. This operation is performed in a database transaction to maintain data integrity.

5. Void

Voiding a Credit Note is also controlled:

• If the Credit Note has been used in allocations, voiding is not allowed
• If part of it has affected the original invoice, the effects are reversed upon voiding
• Finally, the document status changes to Void

This ensures the financial history remains reliable in the accounting database.

In the AF Code accounting software, the Credit Note module includes these pages:

• Credit Notes List (CreditNotes/Index): Display all Credit Notes with filtering by customer, status, date, and number
• Post from List: Direct posting from the list page for Credit Notes in Draft status
• Void from List: Void issued Credit Notes with business rule validation
• Create Page: New Credit Note creation form with complete validation
• Edit Page: Edit Credit Notes in Draft status
• Apply Page: Dedicated page for applying Credit Notes to customer invoices

These pages are clearly implemented in the Accounting area and controlled with separate permissions. For the convenience of accountants in Afghanistan, AF Code Company has designed a simple and effective user interface.

In the AF Code system, these permissions are defined for Credit Notes:

• View: Ability to see the list and details of Credit Notes
• Manage: Ability to create, edit, and delete Draft Credit Notes
• Post: Ability to change Credit Note status from Draft to Issued and apply to invoices

This separation is very important for organizations operating in Afghanistan that want to restrict financial document posting to specific individuals. AF Code Company has implemented these access levels in the accounting database.

The main differences in the AF Code accounting database:

In the AF Code accounting software, these two entities are completely independent, but both play roles in customer account settlement and reconciliation.

Assume customer 'A' has an invoice for 100,000 AFN. Later, it turns out that 20,000 AFN should be deducted (e.g., due to product return or price adjustment).

Steps in the AF Code system:

1. The company issues a Credit Note for 20,000 AFN for customer 'A' (Issued status)
2. This Credit Note is applied to the relevant invoice in the Apply page
3. The system decreases the Credit Note's remaining amount and updates the invoice balance
4. The invoice balance decreases from 100,000 to 80,000 AFN
5. The Credit Note is closed with zero remaining amount (fully consumed)

This exact process is performed systematically and traceably in the AF Code accounting database. All stages are visible in reports, and auditors can follow the complete operation trail.

This example shows how AF Code Company, through AR module design, has enabled precise receivables management for businesses in Afghanistan.
