Sequential Order Numbers for WooCommerce stores every formatted order number on the order itself. Each new order gets _order_number on wc_orders_meta with the configured prefix, the sequential integer, and the optional suffix (for example, ORD-2024-001234). The base WooCommerce id on wc_orders stays untouched. The plugin admin shows the formatted number in the order list, but never aggregates by prefix or year segment.

SleekView Charts reads _order_number directly and lets the team chart by the prefix and year segment of each formatted number. A Bar ranks orders per prefix (ORD vs SUB vs WHL) for businesses that route different order types through different number ranges. A Number card sums revenue per prefix to see which channel earns the most. A Line chart plots the highest sequential number per day to confirm no gaps. An Area chart plots daily order issuance from date_created_gmt.

This is a reading layer, not a replacement for the numbering engine. The plugin still owns the actual sequence allocation and the formatted-number generation. SleekView Charts adds the dashboard the plugin admin does not lay out: prefix mix against revenue per prefix against daily issuance on one saved screen, scoped per role, embeddable for accounting that needs ordered, prefixed numbers without WooCommerce admin access.

Sequential Order Numbers for WooCommerce handles a problem every accountant and many tax authorities care about: orders with gapless, prefixed, formatted numbers that match the figures on invoices. The plugin already writes the formatted number to _order_number on wc_orders_meta for every order. What the plugin does not do is treat that number as data to chart by.

Multi-channel stores route retail through ORD, wholesale through WHL, and subscriptions through SUB but the only way to see how many orders sit in each range is to scroll the orders list and read the prefix. Accountants who want issuance volume per month use a CSV export. SleekView Charts reads _order_number directly and groups by its prefix and date segments.

Accounting sees the prefix-revenue bar and the issued-orders KPI. Owners see the daily issuance area chart. Multi-channel stores see the orders-per-prefix donut.

The plugin keeps owning the actual sequence allocation; SleekView adds the in-WordPress reading layer that turns the formatted number into a real dashboard.
