Credit and corrective invoices

1. What are they and when to use them?

In StarNapp you can’t edit or delete issued invoices, so any correction must be done through:

Corrective invoice

It’s used when we need to fix mistakes in an original invoice:

• Incorrect price

• Incorrect VAT applied

• Wrong customer details

• Invoice cancellation

It replaces the original invoice.

Credit invoice

It’s a type of corrective invoice with negative amounts. It’s used for:

• Product returns

• Commercial discounts

• Fixing overcharged amounts

It offsets the original invoice (it doesn’t cancel it).

2. How to create a corrective or credit invoice

Step by step:

1. Go to the incorrect invoice

2. Click on the “CONVERT” button (top right)

1. A pop-up will open where you should:

   • Select the invoice type:

     • Rectifying

     • Credit note

   • Choose the format:

     • Detailed

     • Summarized in one line

   • Decide if you want to transfer the notes from the original invoice
     

     

2. Confirm the action

3. How the credit note invoice works

• The system creates a copy of the original invoice with negative amounts

• The invoice is generated in draft status, so:

  • You can edit it (for example, if the credit is partial)

• The title is updated automatically:

  "Corrective invoice for differences (Credit) | FCT-XXX"

Result:

• The original invoice is NOT canceled

• Both invoices offset each other:

  • Final balance = 0 (if the credit is total)

  • Or adjusted balance (if it’s partial)

4. How the corrective invoice works

• It’s created following the same process

• The amounts appear in positive

• The system automatically changes:

Title:

"Substitute corrective invoice | FCT-XXX"

Notes:

"This invoice is a corrective invoice that replaces the original invoice FCT-XXX"

Result:

• The original invoice is voided

  

• The new invoice becomes the valid one

Voided invoices don’t affect the customer’s account status.

5. Important considerations

• Don’t create corrective invoices with negative amounts

  • It can create discrepancies in balances

  • The original invoice is voided, leaving the offset without a basis

• Use:

  • Credit note → to subtract/negative amounts

  • Corrective invoice → to fully replace
