Frequently Asked Questions

Can I purchase one license and use it in multiple accounts?

A separate license is needed for each production account. We do not charge for testing or development accounts.

What is the difference between Multi-Storefront and multiple accounts?

It might seem like multi-store and multi-storefront are the same thing, but they are very different from an architectural standpoint. This is a BigCommerce architectural design of how stores operate and not controlled by third party apps.

Merchants may choose multi-store architecture in order to have separate "stores", catalogs, and functionality, by brand, segment or region.

Merchants may choose to have a multi-storefront architecture in order to have one store, catalog, etc. and leverage channel based storefronts for different brands, languages, currencies etc. (feature release by BigCommerce in March 2022)

Can I give access to the app to other store users?

Yes! BigCommerce has released a new feature where the store owner can now grant access to the apps to each store login. To grant access, edit the permissions for the specific user, scroll down to the Single-Click apps section and click the InStockNotify box.

Can I customize the email my customers receive?

Yes! We include an editor so that you can customize the email notification your customers receive.

I have a returned item and if I add that back into inventory, will all emails go out?

You can adjust the inventory threshold that must be met before notifications go out from the Settings area once in the app.

Can I limit the number of emails that go out for a product to the number in inventory?

You can limit the number of notifications for a product that go out from the Settings area once in the app.

Please note that with this setting, the limited number of emails will be sent every 6 hours (hourly if on the premium plan). Example: 10 notifications awaiting for a product. 2 are now in inventory, 2 will get sent with 8 remaining. This process repeats every 6 hours (hourly if on the premium plan) until the products are sold, or all notifications have been sent.

How soon after I update inventory will emails go out?

We monitor the inventory levels of the products your customers are interested in every 6 hours (hourly if on the premium plan). When the app sees that a product is back in stock, the email will be sent.

I just updated my inventory, can I run an inventory check right away?

Yes! From the menu in the app, select Registrations -> Inventory check. This will start the process to monitor the inventory of your store.
