Fitment Data add-on

The Fitment Data add-on is $150 per month on top of any plan, including Starter. It covers wheels and tires only — every other category runs on the sources you connect, and most stores never need this.

What switching it on does#

It sets an entitlement on your shop. From that moment, spec matching is evaluated at query time across search, collections, the product verdict, the fits endpoint and the fitment table.

There is nothing to sync and no reindex needed — matching happens per request, so the change is visible immediately.

Turning it on#

Ask us. It is granted per shop rather than purchased self-serve today; the Sources screen shows a contact link where a purchase flow will eventually be. When self-serve billing for add-on line items ships, it becomes a second subscription line on your Shopify invoice.

We would rather say that plainly than build a fake button.

Turning it off#

Also immediate. Products revert to the fitment your own sources provide, which usually means more unconfirmed verdicts and fewer honest negatives. Nothing you own is lost — your mappings, editor overlays and sources are untouched, because the add-on never wrote to them.

Is it worth it for you?#

Yes, if:

• You sell wheels or tires, and have clean spec metafields (bolt pattern, diameter, width, offset, bore) but no product-to-vehicle mappings.
• Your suppliers give you good catalogs and poor fitment files.
• You want does not fit to be an answer your store can give, not just unconfirmed.

No, if:

• Your fitment already comes from a supplier feed you trust, and coverage is above 90%.
• Your catalog is mostly accessories and universal parts, where specs don't decide fitment.
• Your product data has no specs at all — the add-on judges specs; it cannot invent them.
