Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
WooCommerce merchants using automated tax services struggle with shipping-address-based tax miscalculations during checkout. No search volume, but the pain (lost revenue, compliance risk) is documented in forum threads.
Competition & the opening
Tax plugins (TaxJar, Avalara integrations) and WooCommerce's native tax engine exist; the gap is a debugging and repair tool to diagnose and fix calculation errors without re-configuring the entire tax system.

Why now
WooCommerce tax logic bugs persist despite prominence; compliance risk drives demand for niche fixes.
