Hi @info2377. This error occurs because the 0% VAT rate in Tradify doesn't have an identical VAT rate in your QuickBooks Online tax settings. The naming mismatch causes the sync to fail, and both systems must use the exact same tax code name and rate to communicate accurately.
To start, we recommend going to the Taxes tab and clicking Add/edit tax rates and agencies to confirm that a 0% VAT rate exists. This ensures your QuickBooks tax settings align with the requirements for receiving data from Tradify.
If the rate is missing, create a new one named Zero VAT with a value of 0.0% to match Tradify exactly. This alignment allows both programs to proceed with seamless data transmission. Additionally, check if the rate was accidentally deactivated by clicking the Small Gear icon above the tax list and selecting Include inactive.
When everything checks out within QBO, we recommend reviewing your Tradify settings to ensure they are accurate. Aligning these names removes mapping challenges and allows invoices to flow into your books without error. Once you save the changes, simply re-sync the invoice from Tradify to see it appear in QuickBooks.
