Editing and Unlocking Sent Invoices

Sometimes you need to make changes to an invoice after it's been sent. TallySpark protects you from accidental edits with a smart unlock system while still giving you flexibility to make necessary corrections.

When You Might Need to Edit Sent Invoices

Common scenarios where editing is necessary:

  • Correcting pricing errors or quantity mistakes
  • Adding or removing line items based on scope changes
  • Updating client contact information
  • Adjusting payment terms after client discussion
  • Fixing typos in descriptions or notes

Understanding the Unlock Warning

When you open a sent invoice for editing, you'll see a yellow warning banner:

"This invoice has been sent to the client. Changes to items may affect communication and expectations."

This warning appears because:

  • Your client has already received the original invoice details
  • Changes to amounts may create confusion
  • The client may have already initiated payment
  • Significant changes might require re-sending

How to Unlock an Invoice for Editing

  1. Navigate to Invoices and open the sent invoice
  2. Click the Edit button to enter edit mode
  3. Read the yellow warning banner carefully
  4. Click Edit Anyway (unlock icon) to proceed
  5. A notification appears: "Invoice unlocked for editing"
  6. The items section becomes active and editable
  7. Make your necessary changes
  8. Click Update Invoice to save

Session-Based Unlock Behavior

TallySpark uses session-based unlocking for added security:

  • Unlock Duration - The invoice remains unlocked only for your current session
  • Session Expiry - If you navigate away, the invoice automatically re-locks
  • Re-unlock - You'll see: "Edit session expired. Click 'Edit Anyway' to unlock again."
  • Team Protection - Other team members must separately unlock

Best Practices for Communicating Changes

When you edit a sent invoice, follow these professional practices:

  1. Contact Your Client First - Explain the changes before updating
  2. Document the Reason - Add a note explaining why changes were made
  3. Re-send If Significant - For major changes, send the updated invoice
  4. Keep Records - Export the original invoice before making changes
  5. Be Transparent - Use notes to highlight what changed and why

For minor corrections that don't affect amounts, you may not need to notify your client. For anything that changes the total, clear communication maintains trust.
