Checkout Requirements
Require signatures, customer addresses, last-four card digits, tax, or multiple-card payment behavior by method.

How to Require a Signature by Payment Method
Open Settings → Payment Methods.
Go to Options.
Under Signature, select every payment method that must collect a signature.
Select Update Options.
Test a checkout using one selected method.
You can require a signature even for Cash if that is your store policy. Leave the selection empty when no method requires one.

How to Require a Customer Address
Open Payment Method Settings.
Under Options, find Require Address.
Select each payment method that must have customer address information.
Update the options.
Test checkout with and without a complete customer address.
Use this for payment or compliance workflows that require address collection. Avoid requiring unnecessary personal information.

How to Collect the Last Four Card Digits
Open Payment Method Settings.
Find Last 4 or Collect last four digits for.
Select the supported locked card methods that require this information.
Update the options.
Test the checkout prompt.
Enter only the requested last four digits. Do not place full card numbers in notes or other fields.

How to Force Tax for Supported Card Methods
Open Settings → Payment Methods.
Under Options, find Force Tax.
Select the supported Credit or Debit methods that must always apply tax.
Select Update Options.
Test with an eligible taxable item.
This helps prevent an employee from unintentionally removing applicable tax when the selected card method requires it. Configure tax rates and product taxability correctly before enabling the rule.

How to Allow Multiple Card Payments
Open Payment Method Settings.
Find Multiple Card Payments.
Enable it when one sale may use more than one credit or debit card.
Update the options.
Test a split-card checkout.
This controls multiple card tenders within a sale. Employees should confirm each approved amount and the remaining balance before completing checkout.

How Payment-Specific Requirements Work at Checkout
Requirements are evaluated from the payment method selected for the sale. A method may trigger one or more prompts for signature, customer address, last four digits, or forced tax.
Configure only requirements that match store policy. After changes, test every affected method on a safe transaction so employees understand the new prompts and cannot complete checkout with missing required information.
