Print Invoices & Packing Slip Labels for WooCommerce stores the sequential invoice number to _bkap_invoice_number (or the equivalent prefixed meta key in newer versions), the issue date to _bkap_invoice_date, packing-slip identifiers to parallel meta keys, and a generated-PDF flag to _bkap_pdf_invoice on each order. The plugin is reliable, but the admin only shows one order at a time, which means issuance trends and document mix are invisible to finance and to ops.

SleekView Charts pivots those meta keys into chart cards on a single dashboard. A Number card counts invoices issued this period. An Area card plots daily issuance from the invoice-date meta so generation outages show the same day they happen. A Pie card splits issued documents by type (invoice, packing slip, shipping label). A Bar card ranks customers by invoice count, which surfaces VIP accounts and unusual refund patterns in the same chart.

Because chart cards and the SleekView audit table share one query layer, switching from the chart view to the matching table view shows the exact orders behind any bar or slice with the same filters applied. Sequential-gap detection runs as a computed column, so a Number card can flag missing invoice numbers as a daily KPI for compliance leads.

Invoicing is one of those quiet operational systems that only gets attention when it breaks. Print Invoices & Packing Slip Labels for WooCommerce generates documents reliably and writes the right meta keys on every order. The problem is that the resulting dataset is rarely visualised, which means trends that matter (rising reissue volume, falling issuance after a release, a single customer suddenly accounting for 30% of invoices) hide behind individual order screens until someone runs a custom report.

A chart dashboard built directly on the bkap meta closes that gap with four small cards. Daily issuance plotted as an Area chart catches outages in hours rather than weeks. Document-type donut surfaces fulfilment problems before finance flags them.

Customer-frequency ranking links invoice work to revenue concentration, information stores already need for support staffing and account management. Because charts and tables share one query layer, every aggregate drills into the rows behind it on click.
