WooCommerce EU VAT Number adds the EU B2B reverse-charge flow to WooCommerce: a VAT number field at checkout, a VIES validation call against the customer's VAT ID and order meta marking each order with the validation result. The meta keys _vat_number, _vat_number_is_valid and _vat_number_is_validated travel on every B2B order, alongside the standard billing_country WooCommerce stores.

The default reporting surface treats those orders the same as B2C orders, so VAT-exempt revenue, validated-versus-unvalidated splits and per-country B2B mix are buried in the order list. Finance and operations teams end up exporting CSVs once a quarter and pivoting in spreadsheets to file MOSS or OSS returns.

SleekView Charts reads wp_wc_orders joined with wp_wc_orders_meta and renders the B2B slice as chart cards. A Number card counts validated B2B orders. A Pie shows the validation-status mix so finance sees how much exemption rests on unvalidated VAT numbers. A Bar ranks billing_country by exempt revenue. An Area trends B2B orders per week so account teams see cadence, not just totals.

WooCommerce EU VAT Number sits in the most regulated path of an EU store: B2B reverse-charge orders that are tax-exempt only when the customer's VAT ID validates against VIES. Default WooCommerce reports treat those orders like any other and finance teams pivot CSVs every quarter to file OSS and MOSS returns. SleekView Charts reads the order and VAT meta the plugin already writes and renders the B2B slice as a dashboard: a validated-order KPI, a validation-status Pie, a per-country exempt-revenue Bar and a weekly cadence Area.

Same _vat_number meta, same billing_country and order_total, completely different decision posture. The dashboard is the difference between knowing the store has B2B revenue and knowing exactly how much, where, and how much of it rests on validated VAT IDs.
