WooCommerce EU VAT Assistant is the long-running Aelia plugin that solves the EU place-of-supply rules: it determines the customer's country from IP and billing address, captures two pieces of location evidence, applies the right VAT rate per member state and records all of it as order meta. Each order ends up with _vat_evidence, the chosen country, the applied rate and B2B markers when a valid VAT number was entered.

The plugin ships its own MOSS report inside WooCommerce, which is useful for filing but is built as a tabular export by member state. There's no chart surface for trending VAT collected over time, for spotting an evidence-source skew (IP versus billing) or for comparing B2B exempt share to B2C taxable share.

SleekView Charts reads the same order tables and the EU VAT Assistant meta, then renders the slice as a dashboard. A Number card sums VAT collected in a quarter. A Pie shows the evidence-source mix. A Bar ranks countries by VAT collected. An Area trends VAT per week so finance sees seasonality, not only the quarterly total their MOSS workbook produces.

EU VAT Assistant has spent over a decade turning the place-of-supply rules into clean WooCommerce order meta: country, rate, evidence source and B2B status on every order. The built-in MOSS report is excellent for filing day and unhelpful in the eleven weeks between filings, when finance teams want trends, drift detection and evidence-quality checks. SleekView Charts reads the same meta the plugin already records and renders the slice as a quarter-by-quarter dashboard.

A VAT-collected KPI anchors monthly close, an evidence-source Pie exposes audit risk, a per-country Bar shapes MOSS prep and an Area on date_paid surfaces the seasonality MOSS PDFs never reveal. Same order rows, same _order_tax sums, completely different decision posture between filings.
