Why Validate Before Xero Import?

Avoid Import Failures

Xero invoice imports fail silently on bad data. Wrong date formats, missing ContactName, or invalid TaxType cause rejections without clear errors. Validating first identifies problems before you waste time troubleshooting.

What This Tool Checks

We validate your invoice CSV against Xero requirements: - Required columns present (ContactName, InvoiceNumber, InvoiceDate, DueDate, Description, Quantity, UnitAmount, AccountCode, TaxType) - Regional date formats (DD/MM/YYYY for UK/AU/NZ, MM/DD/YYYY for US) - Multi-line invoice structure (same InvoiceNumber) - Currency values valid You get a detailed error report with row numbers to fix issues.

Common Target Import Errors

Issues you might encounter when importing Source data to Target - and how we solve them

Missing Contact Name

The ContactName column is required for each invoice

(blank ContactName)
John Smith

Each invoice needs a contact name (customer)

Add contact names; Xero will create contacts if they don't exist

Invalid Date Format

Dates must match your Xero region format

2025-01-15 or 01/15/2025 (for UK)
15/01/2025 (UK) or 01/15/2025 (US)

UK/AU/NZ uses DD/MM/YYYY, US uses MM/DD/YYYY

Reformat dates to match your Xero organization's region

Duplicate Invoice Number

Xero rejects InvoiceNumber values that already exist

INV-1001 (already exists in Xero)
INV-1002 (unique)

Each invoice needs a unique InvoiceNumber

Check Xero for existing invoices before importing

Tax Type Not Found

TaxType must exactly match a configured tax rate in Xero

20% VAT
20% (VAT on Income)

Use exact tax rate names from Xero Settings > Tax Rates

Update TaxType to match Xero's configured tax rates exactly

Missing Account Code

AccountCode is required for each line item

(blank AccountCode)
200

Every line needs a valid Xero account code

Add account codes from Xero Settings > Chart of Accounts

Frequently Asked Questions

Required columns are ContactName, InvoiceNumber, InvoiceDate, DueDate, Description, Quantity, UnitAmount, AccountCode, and TaxType. Optional: EmailAddress, Reference, InventoryItemCode, Discount, Currency.
UK, Australia, NZ, and Europe use DD/MM/YYYY. United States uses MM/DD/YYYY. Select your region to validate against the correct format.
