Great app for reducing customer mistakes during checkout. The instant address validation helps avoid shipping issues, and customizing fields is very straightforward. It integrates smoothly with Shopify and keeps our checkout process clean and reliable.

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.

Hi 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.

The customization options are also really helpful — reordering and renaming checkout fields to match our branding was super easy.
