Locksmith

Darn Locksmith for being too good! Due to Shopify''s fee structure on sales, I subscribed to a higher plan than I probably needed. Which meant that I was placed into a higher tier than I'd hoped for Locksmith. The dilemma is, I couldn't bring myself to reach out to ask for a lower price due to how well their plug-in works!
You see, I offer custom products that I only want people to be able to add to their carts (since I despise invoicing as I also have an expansive catalog) AFTER I send them back a proof of what I'd be making for them. Locksmith gives me the peace of mind of protecting my custom products from ordering ahead of a request which is invaluable. It also works with Shopify's app which of all the plug-ins I've had to subscribe to, is the only one.
Alls this to say, if you need to restrict products, I HIGHLY recommend Locksmith as it's been invaluable to my sanity and business model!

I would recommend this app. The app developer work with you to figure out if/how this app can work for your store or not. Keep in mind you may need a few days to get it dialed 100%, but the devs will work to deliver you a working solution.

Great experience so far, extremely helpful in setting up our Wholesale Jewellery Store with limited access to customers. Ken from their team not only understood the entire flow but gave suggestions and helped in setting up the store till the end. They extended the trial for us to test things out.

I love this so much I'm going to jump in to Mechanic next. Locksmith is the perfect solution to a problem I had and devs tried charging me hundreds when this took me 10 minutes and not much per month. Thanks for being awesome guys!

The support is excellent. When I was struggling with something, the team did not just explain what was happening and how to fix it, they actually DID the fix for me and fast! Outstanding customer service.
