Can I run Prime Lock and Sami B2B Lock at once?

You can, and during a migration it is a reasonable thing to do: leave Sami's rules in place while you rebuild them in Prime Lock, then switch off one side. Running both permanently is not a good idea, because two apps hiding the same price will fight over the same theme elements and the result is hard to debug. Once your Prime Lock rules match, uninstall the other app.

Will my customer tags carry over?

Yes. Both apps read Shopify's native customer tags, which live on the customer record and belong to your store, not to any app. Nothing is copied or migrated: the same wholesale tag that opened a gate before opens it after. Uninstalling either app leaves the tags exactly where they were.

What happens to my locked pages' SEO when I switch?

Nothing, if both apps were hiding SEO-safely. Sami publishes SEO-safe hiding, so your locked products should already be indexed with the price withheld. Prime Lock keeps the same pattern: the page stays indexable, the title, description, images and schema stay intact, and only the price is withheld. You can additionally strip the price from the Product structured data and the Shopping feed, which is what protects a MAP agreement.

Sami B2B Lock is the safest pick in this category if your problem is genuinely about hiding. It has more reviews than any other app here by a wide margin, the rule builder is mature, and the details that trip up cheaper apps, such as hiding the price from Google and handling date windows, are handled properly. Prime Lock is the better fit if you need the gate to survive a shared cart link, or if you need to vet wholesale applicants rather than just hide things from them.

Honest assessment

Where Sami B2B Lock is a good fit

926 reviews at 4.9 is not an accident. Sami has been iterating on this app since 2023 and the rule builder shows it: you can lock by customer tag, by email address, by passcode or by date window, and combine those conditions without fighting the interface. Locks are unlimited on the paid tiers. The free plan is a genuine free plan rather than a trial, though it allows one lock, so a catalog of any size means a paid tier.

The part worth calling out is that hiding prices from Google is treated as a first-class feature rather than an afterthought. A lot of apps in this category hide the price in the rendered theme and leave it sitting in the product structured data, where a shopping comparison engine reads it happily. Sami does not make that mistake.

If you want the most-trodden path in this category, this is it: the app where any problem you hit has already been hit by someone else and answered in a support thread. That is worth real money on a live store.

The difference

Where Prime Lock is different

Prime Lock compiles every lock into a Shopify Function that validates the cart and the checkout server-side. That is a different layer from theme-side hiding: when a buyer without the right tag reaches checkout, the Function rejects the order regardless of how they arrived, whether by a guessed product handle, a cart permalink pasted into a browser, or a link forwarded by a trade customer. Sami hides thoroughly, but checkout-level validation is not part of its published feature set, so a shared cart permalink is still a shared cart permalink.

The second gap is vetting. Sami gates access by tag, which means something else in your stack has to decide who gets the tag. Prime Lock renders its own registration form through an app proxy, creates the applicant as a customer tagged pending-approval, stores the extra fields as metafields, and gives you an approval queue where one click applies the tag, opens the locks and sends the welcome email.

Both of those run on the free plan. Checkout enforcement is not a paid upgrade here.

Migration

Switching from Sami B2B Lock

Step 1
Note your existing rules
Write down every rule you have configured in Sami B2B Lock: what it protects, who it lets in, and any schedule attached to it. This is the only step that takes real time, and doing it before you install anything makes the rest mechanical.
Step 2
Recreate them as locks
Build each rule in Prime Lock as a lock: pick the lock type, set Applies to, set Who can unlock, and add a schedule if the original had one. Your customer tags carry over unchanged, because both apps read Shopify's native customer tags rather than storing their own copy.
Step 3
Uninstall Sami B2B Lock and check your theme
Sami writes its configuration into its own admin rather than into your theme, so removing it is clean. Even so, check your theme files for any custom snippets you or an agency added around the lock, since those are yours and will not be removed with the app. After uninstalling, view a locked product as a guest and as a tagged customer, and try a direct cart permalink to confirm the checkout Function rejects it.
