Are you seeing this error in the MyWorks Sync log when trying to sync an order to QuickBooks?

Error:

Error:5040: [System underload error., The database is overloaded. Please retry after 90 seconds.]

Cause:

This error usually indicates that:

  1. Your tax settings in MyWorks Sync  > Settings > Tax are not correctly set, or,
  2. Your tax rates are not correctly or only partially mapped in MyWorks Sync > Map > Tax Rate

Resolution:

  • You have a valid QuickBooks Non-Taxable rate set in MyWorks Sync > Settings > Taxes. This is usually Out of Scope or No VAT - but it can vary based on your QuickBooks company. If this is set to Exempt, try changing to a different 0% rate.
  • Check that all the dropdowns in MyWorks Sync > Map > Tax Rates are set, each tax rate in WooCommerce should be mapped to a corresponding tax rate in QuickBooks. If you have a 0% rate displaying here, it needs to be mapped to a 0% rate as well.
  • Check out our documentation on mapping taxes here
