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:
Your tax settings in MyWorks Sync > Settings > Tax are not correctly set, or,
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.
