SPOD has a system called Batch Authorization Payments for processing orders, and the following article explains how it works. 

Once one of the following thresholds is met, SPOD will make a Batch Authorization Payment on your card. 

• 30 orders 
• $300 order value

If neither of the above thresholds are in met in 6 hours we will make a Batch Authorization for the amount of orders you have received. Regardless of if you didn't reach 30 orders or $300 in order value, 6 hours after the first order is placed SPOD will make a Batch Authorization Payment. 

Once your products are shipped we will still bill each order separately on your credit card. 

Example 1:

Your shop receives 30 separate orders for a Men's T-Shirt in a time span of 2 hours. As you have reached 30 orders SPOD will make a Batch Authorization Payment of $298.80 on your credit card. 

These orders will be sent to production. 

Once the orders are shipped SPOD will charge 30 separate payments of $9.96 on your credit card. 

Example 2:

Your shop receives 4 separate orders for a Men's T-Shirt. 6 hours after the first order was placed SPOD will make a Batch Payment Authorization of $39.84. 

These orders will be sent to production. 

Once the orders are shipped SPOD will take 4 separate payments of $9.96 from your credit card. 

Below is an example of how you can trace the Batch Authorization Payments in your order page in the app. 

You can search for the Batch ID and it will show every transaction that has been made in that Batch Authorization Payment.
