# What is the difference between recurring invoice and auto charge?

If you’re charging your customers on a regular basis for the same set of products or services you offer, you can simplify the process by converting the invoice into a recurring invoice. This will allow you to automatically generate invoices at periodic interval.

However, auto charge is a feature of recurring invoices where you can automatically charge your customer’s credit card or debit money from their bank accounts via ACH payments whenever a recurring invoice in generated.

To convert an invoice into a recurring invoice:

*   Go to the **Invoices** tab and select the invoice which you wish to convert into a recurring invoice.
*   Click on the **More** drop-down and select the **Make Recurring** option.
*   Set the interval at which the invoice should recur and click **Save.**

To enable the auto-charge feature:

*   Click on the Gear icon on the top right corner and navigate to **More Settings -> Preferences -> Recurring Invoice -> Create, Charge and Send Invoices**. Make sure this option is selected and click **Save**.
    
*   You need to integrate with a payment gateway that supports the ‘Auto-Charge’ feature.
    
*   Once you have completed the steps mentioned above, navigate to the Contacts module, select a contact and click on **Add New Card** from the **More** drop-down.
    
*   Enter the credit card details and click on **Save**.
    

The contact’s credit card details will now be saved in your account and you can use it charge him/her.
