Checkout Field Editor already has the data. Every custom field you add to the billing, shipping, or additional sections of the checkout writes to postmeta on the order with the chosen field name as the meta_key and the customer input as the meta_value. On HPOS stores the same values land in wc_orders_meta. The default admin shows the field per order, one order at a time, and the field rules live in the thwcfd_fields option, so reading aggregate fill rate or the distribution of values means clicking through orders.

SleekView Charts reads the same order metadata and turns it into chart cards on a single dashboard. A Number card counting orders that have a non-empty value for a custom meta_key like billing_vat_number, a Donut splitting orders by a select field's meta_value, a Bar of the top values for a free-text question, and an Area chart of submissions per day. Each card is a saved query against the live order tables, not a one-off export.

This sits alongside the Checkout Field Editor settings, not on top of them. The plugin's field rules screen still owns where each field shows, whether it is required, and any conditional logic. SleekView Charts adds the reading layer that lets you measure the fields you added: fill rates per field, value distribution across options, daily submission volume, and which orders carry which answers. Custom fields are useless if nobody reads them; SleekView turns them into dashboards anyone on the team can share.

Checkout Field Editor adds the fields, but the reading side is what makes them worth the friction at checkout. Every value lands in postmeta on the order, or wc_orders_meta on HPOS stores, with the field name as the meta_key and the customer input as the meta_value. The default admin shows that data per order, one click at a time, so reading aggregate fill rate, the distribution of values for a select field, or the daily submission trend usually means a CSV export and a spreadsheet.

SleekView Charts reads the same order metadata and turns it into chart cards on one saved dashboard. Marketing sees the value distribution donut for a how-did-you-hear question. Finance watches the VAT-number fill rate KPI.

Operations reads the top-values bar for delivery instructions. The Checkout Field Editor admin keeps owning field rules, conditional logic, and required validation; SleekView Charts adds the reading layer that lets the team actually use the data they collect at the checkout.
