Helium Customer Fields is the best registration and approval app on Shopify, and it is not close. It is also not a lock app. It collects and vets applicants, and something else has to hide the catalog and stop the checkout. If your registration flow is genuinely complex, Helium is deeper than what we ship, and running Helium alongside Prime Lock is a sensible configuration rather than a compromise.
3 of the 4 capabilities Helium Customer Fields publishes are on the Prime Lock free plan
The remaining file upload on form sit on our $9.99 Pro tier. Everything else, including checkout enforcement, is free and stays free for your store.

Honest assessment
Where Helium Customer Fields is a good fit
The form builder is the real product: drag-and-drop, multi-step forms, conditional logic, custom fields written to metafields, file uploads, email verification, and customer self-service editing so a buyer can update their own company details later without emailing you. Nothing else in this category is close on form depth.
The approval side is equally mature, with conditional auto-tagging plus Flow and Zapier hooks, so an approval can trigger whatever else your business does when a wholesale account opens. If your vetting involves more than one person or more than one system, Helium is built for that and we are not.
If your problem is collecting and vetting B2B applicants, Helium solves it more completely than anything else on the App Store, including us. We would rather say that than pretend otherwise.
The difference
Where Prime Lock is different
These two apps do not really compete; they overlap. Helium does not lock anything, and locking and checkout enforcement are not part of what it does. Prime Lock compiles locks into a Shopify Function that validates the cart and checkout, hides prices and content on the storefront, and includes a registration form and approval queue that cover the mainstream case.
The honest comparison is scope against depth. Prime Lock covers the form, the approval queue, the auto-tagging, the locking and the enforcement in one install, on a free plan. Helium covers a narrower slice far more deeply, starting at $15/month.
Plenty of merchants run Helium for the form and a lock app for the gate, and pay for both. That combination works with Prime Lock: Helium creates and tags the customer, Prime Lock reads the tag and enforces it. Use our built-in form if it is enough, and keep Helium if your flow needs what it does.

Migration
Switching from Helium Customer Fields
Step 1
Note your existing rules
Write down every rule you have configured in Helium Customer Fields: 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 Helium Customer Fields and check your theme
If you are keeping Helium for the form, you are not switching at all. Point its approval automation at the tag Prime Lock reads, and you are done. If you are replacing it, export your existing submissions first, since form submissions live in Helium rather than on the customer record. 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.
