Why only flag first-time buyers rather than all orders?

First-time buyers are statistically more likely to pick the wrong part because they are unfamiliar with your fitment tables. Returning customers tend to know their vehicle details and have ordered correctly before.

Should I lower the 75 threshold for safety-critical parts like brakes?

Yes. For brake pads, discs, or suspension components, consider reducing the threshold to capture smaller orders or removing the total condition entirely and adding a specific category condition instead.

Does this rule work with guest checkouts?

Guest checkouts show 0 previous paid orders, so they will be flagged. This is usually desirable since guest buyers are the hardest to verify.

How to verify vehicle part fitment on first orders in WooCommerce | Fitment Check rule

The problem

Vehicle parts must match a specific year, make, model, and engine variant. First-time buyers frequently order the wrong part because they are unfamiliar with your catalogue or misread a fitment table. A single wrong-fitment return can cost more in reverse logistics and restocking than the original margin on the sale.

The solution

OrderBadger can flag orders from first-time buyers purchasing car parts or vehicle accessories above a value threshold, giving your team a chance to verify fitment before dispatch.

Who this is for

Online auto parts retailers selling replacement components, performance upgrades, or vehicle accessories where fitment compatibility is critical and returns are costly.

How it works

Evaluates three conditions together: the order must include at least one product in the Car Parts or Vehicle Accessories category, the customer must have zero previous paid orders, and the order total must exceed £75. When all three are true, a yellow warning badge appears and the order is sent to the inbox for review.

Check the customer's vehicle details against the part's fitment data. If your store captures vehicle registration or year/make/model at checkout, cross-reference it. Consider sending a quick confirmation email before dispatching high-value first orders.

Make it yours

Adjust thresholds

Lower 'over £75' to 'over £40' if your typical return shipping cost makes even mid-range wrong-fitment returns painful.
Raise 'over £75' to 'over £150' to focus your team's review effort on the most expensive parts where fitment errors are most costly.

Add or remove conditions

Add 'and at least one product is in the Brakes or Suspension category' to restrict the check to safety-critical parts only. …tomer has 0 previous paid orders and order total is over £75 and at least one product is in the Brakes or Suspension category
Remove 'and customer has 0 previous paid orders' to flag all fitment-sensitive orders regardless of customer history, useful during a catalogue migration when part numbers may have changed.

Good to know

This rule only flags first-time buyers. Repeat customers who order the wrong part for a different vehicle will not be caught - consider a separate rule for high-value orders from any customer.
Fitment verification itself is manual. The badge surfaces the order for review but does not validate compatibility automatically.
Products must be correctly categorised as Car Parts or Vehicle Accessories in WooCommerce for the rule to work.
