Valider has been a great addition to our store. It helps prevent address mistakes, makes checkout more flexible, and gives customers a smoother experience. We’re happy with how much easier it is to manage our checkout now.

The checkout rules give us much better control over how customers complete their orders. We can apply different rules depending on the order and shipping information.

Very useful app for preventing address-related issues. The real-time address validation helps catch incorrect shipping details before an order is placed. It has made our checkout process much more reliable.

Very easy to set up and use. We can create checkout rules based on shipping information and order details without complicated coding. A great solution for Shopify stores.

Really helpful app for keeping our checkout process clean and accurate. The address validation works smoothly and helps catch customer mistakes before they turn into shipping problems. I also like the flexibility of the checkout rules and customization options.

I tested VLD Valider for a few days on my Shopify store, hoping it would help catch address errors. In the past, I rarely had issues, mostly just missing house numbers on orders. Strangely, this app flagged 90% of them as needing corrections. At 0.04 cents per validated order, it’s not worth the hassle or the constant false positives. Save your time and money, stick to manual checks.

Developer repliedHi Cilio Lash Expert admin, I’m sorry to hear that the app didn’t meet your expectations during your testing, and I’d like to take a moment to provide some clarification and help resolve the issue you're facing. The Valider app is specifically designed to validate the shipping address during the checkout process. If any address errors are detected, such as missing house numbers or other discrepancies, the app will flag the issue and prompt the customer to correct the address before proceeding to payment. Once payment is completed, this confirms that the address is accurate. If an order is successfully validated, it will be tagged as "VLD_verified," which indicates that the address has been verified for accuracy. Regarding the fee, please note that the $0.04 charge applies to each validated order. We value your business and would love to help you make the most of the app’s features. Please let us know how we can assist further. Best regards, Sunny Valider Team Show more

I hoped Valider would fix our checkout issues, but it kept flagging valid addresses. Some customers couldn’t finish their orders because of strict rules. The customization options felt confusing, and it took too long to set up. Not the smooth experience we expected.

Developer repliedHi there, I sincerely apologize for any inconvenience you may have experienced. It seems there was a misunderstanding. We have sent multiple emails to your address, but we have not received any response from you yet. Show more

Simple and effective. The app automatically validates customer addresses during checkout. Highly recommend!
