The issue with the Cost of Goods Sold (COGS) going out of sync in SQL-Ledger is a known problem, especially when editing past invoices. Since SQL-Ledger uses the FIFO (First-In, First-Out) method for inventory costing, modifying historical transactions can disrupt the accuracy of your COGS calculations.
Possible Solutions:
- Purchase the COGS Reposting Script:
- The developers of SQL-Ledger offer a script that recalculates and fixes COGS across all invoices.
- You can purchase the script directly from their website:
- After purchasing, you’ll receive instructions on how to run the script to correct your COGS entries.
- Manual Reconciliation:
- If purchasing the script isn’t an option, you can manually adjust the affected transactions.
- Steps to follow:
- Identify all invoices that have been edited and have incorrect COGS entries.
- Adjust the inventory and COGS accounts through general ledger entries.
- Note: This method can be time-consuming and may introduce errors if not done carefully.
- Avoid Editing Past Invoices:
- To prevent this issue in the future, try to avoid making changes to invoices that have already been posted.
- If adjustments are necessary, consider creating adjustment entries or credit notes rather than editing the original invoice.
- Update SQL-Ledger Version:
- Ensure you’re using the latest version of SQL-Ledger, as updates may include fixes or improvements to inventory and COGS handling.
- Always back up your data before performing an upgrade.
- Consult the Community:
- Check the SQL-Ledger forums or user groups for any shared scripts or alternative solutions provided by other users.
- Sometimes, community members develop their own tools to address common issues.
Important Considerations:
- Backup Your Data: Before running any scripts or making significant changes, make sure to back up your database to prevent data loss.
- Test in a Safe Environment: If possible, test any scripts or adjustments in a non-production environment first.
- Seek Professional Advice: If you’re unsure about the process, consider consulting with an accountant or a professional familiar with SQL-Ledger.
