WebToffee PDF Invoices already has the data. Every invoice writes _wf_invoice_number, _wf_invoice_formatted_number, and _wf_invoice_date as order meta. Credit notes from the Pro version add _wf_credit_note_number and _wf_credit_note_date. Packing slips, delivery notes, and shipping labels write similar meta with their own keys. The general invoice settings live in wp_options under wt_pklist_general_settings. The plugin admin renders the documents and lists them per order but never aggregates the document volume.

SleekView Charts reads the same order meta and turns it into chart cards on a single dashboard. A Number card counting orders that have a non null _wf_invoice_number in the current month, a Donut splitting orders into invoice only, invoice plus packing slip, and invoice plus credit note based on which meta keys are present, a Horizontal Bar of top countries by invoice count joined from the billing address, and an Area chart of daily invoice issuance from _wf_invoice_date. Each card is a saved query against the live order meta.

This is not a replacement for the PDF generator. WebToffee still owns the PDF templates, the invoice number sequencing, the UBL and XML output, RTL language support via the mPDF add-on, and bulk printing from the orders list. SleekView Charts adds the reading layer the document generator does not provide: invoice volume KPIs, credit note ratio, and document trends, scoped per role and embeddable on a frontend page.

WebToffee PDF Invoices stores plenty of data. Every order that gets an invoice gains _wf_invoice_number, _wf_invoice_date, and the formatted number as order meta, with parallel keys for packing slips, delivery notes, dispatch labels, and credit notes in the Pro version. The plugin admin focuses on generating the documents themselves and bulk printing from the orders list, which is the right scope for a document plugin.

The reading side is mostly absent. The admin never aggregates how many invoices went out, in which countries, or how often credit notes followed. SleekView Charts reads the same order meta and turns it into chart cards on one saved dashboard.

Finance sees the invoices KPI and the credit note ratio. Operations sees the daily issuance trend during a busy seasonal launch. Tax compliance sees the country bar to keep an eye on EU UBL volumes.

WebToffee keeps owning the PDF templates, the UBL output, and the email attachments; SleekView Charts adds the reading layer that an actual team can share, scope per role, and embed on a frontend page without opening the document generator at all.
