YITH Checkout Manager lets stores add, remove, and reorder fields on the WooCommerce checkout. The captured values land in wp_postmeta on each order (or in wc_orders meta under HPOS): a referral source dropdown, a delivery instructions textarea, a custom company size selector, whatever the store needs. The data is solid, the default admin treats each value as a string on a single order screen.

SleekView Charts reads the same custom field meta keys and aggregates them across orders. Each custom field becomes a chartable axis, and the dashboard answers the recurring marketing and operations questions: how often a field is filled, which option dominates the responses, how the response mix shifts over time, which orders skip the field entirely.

The plugin still owns the checkout field UI and the order edit screen. SleekView surfaces the aggregate so the marketing team can finally read the responses they spent months collecting.

Adding fields to checkout is easy with YITH Checkout Manager, the hard part is making the captured data useful. A referral source dropdown collected for two years is a goldmine of attribution, but only if someone aggregates it. SleekView Charts removes the friction by reading the same meta keys YITH writes and rendering four cards per field.

Fill rate is a number. Response mix is a donut. Top free-text values is a bar.

Volume over time is an area. The marketing team stops asking IT to export the field weekly and starts opening a dashboard, which is the smallest possible step from data hoarding to actually using what the checkout collects.
