German Market stores everything a DACH WooCommerce store needs for legal compliance. Every paid order gets _wgm_invoice_number and _wgm_invoice_date on wc_orders_meta, plus the standard WooCommerce billing_country and tax_class fields on the order itself. OSS calculations write _wgm_oss_tax_country for cross-border B2C sales. Double opt-in confirmations carry timestamps and IP addresses for audit trails.

SleekView Charts reads those same German Market keys and builds chart cards on top. A Number card counts orders where _wgm_invoice_number is set for the month. A Donut splits revenue by billing_country across DE, AT, CH, and other EU members. A Bar ranks tax classes by revenue using tax_class on the order line. An Area chart plots compliant invoice volume per day from _wgm_invoice_date.

This is a reading layer, not a replacement for German Market itself. German Market still owns the actual invoice PDFs, the legal imprint, and the OSS export. SleekView Charts adds the dashboard the plugin admin does not lay out: invoice volume against EU country share against tax class mix on one saved screen, scoped per role, embeddable for the accountant who does not need WordPress admin access.

German Market makes a WooCommerce store legally compliant in Germany, Austria, and Switzerland. The plugin already writes compliant invoice numbers, invoice dates, OSS tax classes, and country-of-supply flags onto every order. What it does not do is lay those numbers out as a dashboard.

The accountant still gets a stack of PDFs, the ops manager still scrolls the orders list, and EU country mix lives only in a per-order field nobody groups. SleekView Charts reads the same wc_orders_meta keys and turns them into chart cards on one saved screen. The accountant sees compliant invoice volume per month and tax-class revenue mix.

Ops sees EU country share so distance-selling thresholds do not sneak up. Management sees the daily invoice trend to spot fulfilment backlogs. German Market keeps owning the PDFs and the legal imprint; SleekView adds the in-WordPress reading layer that turns the data the plugin already stores into something a team can look at on one screen.
