Same item selling twice when I only have 1 in stock?

I launch new products each Wednesday. Some items are hard to find and many people are trying to purchase at the same time. Twice now, an item has sold, and then immediately sold again! I only had one, my quantities were set to “1”,and I do not allow items to sell if out of stock. Ironically, the second time this happened, the same person was involved. Both times she scored a hard to find item, leaving someone else somehow able to complete check out only to later be disappointed. Something very strange is happening. I suspect someone is purchasing my items using BOTS, and it is somehow corrupting the system. I have banned the use of BOTS, but I can’t control what people do. This can’t continue. Twice I have had very upset shoppers both of whom I had to appease with store credit. Does anyone have any insight?

That box is unchecked. That’s why I am so frustrated. I think when BOTS are used to purchase items, they somehow circumvent Shopify’s system

Hello @Mimishell ,

Though configuration should have handled if its resulting in out of items still sold out then refer to this link :

https://help.shopify.com/en/themes/customization/cart/prevent-orders-for-out-of-stock-items

 

If you have some development skills it has some simple code that should be applied.

Hi,
I will copy and paste the response they sent. Please note that I am using
PayPal, Shopify payments, AfterPay and Sezzle as payment gateways. They are
basically suggesting that to avoid conflict, use only Shopify and Paypal,
no third party gateways.

This is Jessa, your Shopify Guru. Thank you so much for patiently waiting
for a response. I have received an update from our technical team about
your concern and they have mentioned that it was happening because of the
offsite payment gateway that you are using.

One of the main risks with using an offsite gateway is the chance to have
an inventory oversell due to a number of checkouts placed simultaneously or
almost simultaneously.

This is something which can happen when there is an offsite/external
gateway in use for the checkout. Because of the way these gateways interact
with Shopify, we're currently unable to apply our [Cart Hold Policy.](
https://help.shopify.com/en/manual/sell-online/checkout-settings)

This stock discrepancy occurs because once the request to move to the
gateway is triggered in the checkout we check for available stock.
If stock is available, then we permit the customer to proceed to the
transaction externally to the Shopify checkout.
However if it’s the case where multiple orders come in at once, they all
have the ability of making it to the external gateway provided there is
still at least 1 stock available when they click *Complete Payment*, this
is because we can't decrement inventory levels until the initial customer
has returned from the gateway with a successful transaction.
Then because other customers were permitted to proceed to the gateway, any
successful transactions they place will also decrement inventory even if
it's already at zero due to the fact there was still at least one in stock
when they began payment and the order was permitted to proceed.

It is a factor that our support developers are working on and they're
constantly testing for a new method of offsite gateways integrating with
our inventory services, but as it currently stands this is something that
can happen with use of an external payment gateway which is not directly
connected to an online checkout, and would not be limited to just Shopify.

The only way to truly avoid this would be to look into moving to a [direct
gateway provider.](https://help.shopify.com/en/manual/payments/third-party

Thank you very much for your prompt response. I understand, that is very bad, this generates many problems. I also have a third-party payment gateway (Openpay). The shopify team should fix this as soon as possible.

Hello there,

We currently get this error so many times in our shop. As we launch new collection at a specific date and time every Sunday. We have many orders appears at the very same time.

We got oversells each time. We now know it's because of our offsite gateway: Payplug.

 

Any update to fix this problem please?
