Troubleshooting
What to do with unsupported tax precision
Some imported order data can contain tax values outside the precision TaxPack's exact arithmetic supports.
Inspect the source record
Use a narrower date range to isolate the source event, then inspect the raw stored tax line and import process.
Build a focused report
Correct the source data through an authorized WooCommerce workflow if it is genuinely wrong, then rerun the same report.
Read the result
TaxPack stops on unsupported precision rather than rounding or returning a partial report.
A concrete example
A value with more than eight decimal places needs source review; displaying two decimals in a spreadsheet does not repair it.
Avoid this mistaken conclusion
Do not truncate the CSV or silently round the source value to force the report through.
