Payment Functionality Settings

Payment functionality settings control checkout behavior around customer data, taxes, risk checks, cart behavior, email delivery, and rate limiting.

Open Payment settings, then use Payment Functionality.

Checkout and customer details

Use these settings to decide what checkout asks for and how orders are processed:

1. Collect Billing Details asks customers for billing details during checkout.
2. Enable VAT collects VAT during checkout.
3. VAT inclusive product pricing includes VAT in product prices instead of adding it on top.
4. Disable Checkout Email stops asking customers for an email address during checkout. Delivery emails cannot be sent when no customer email is available.
5. Send Delivery Email controls whether SellApp sends the delivery email after purchase.

Use billing details and VAT settings when your tax, invoicing, or processor workflow requires them.

Store risk and cart controls

Use Blacklist On Dispute to automatically blacklist a customer's email and IP if they open a dispute.

Use Allow VPN Purchases when customers using a VPN or proxy should still be allowed to buy. Leave stricter risk controls in place when fraud prevention is more important than allowing VPN traffic.

Use Disable Shopping Cart when customers should buy one product at a time instead of building a cart.

Minimum spend and descriptor

Use Minimum Spend to require customers to spend at least a certain amount before checkout.

Use Customize Billing Descriptor to change the text customers see while checking out. The descriptor is limited to 20 characters.

Checkout rate limits

Checkout rate limits control invoice creation attempts per store. You can set:

1. Customer attempts per hour for the same IP and email combination.
2. Optional limits per IP.
3. Optional limits per email.
4. Optional limits per checkout session fingerprint.
5. A window in seconds before attempts are allowed again.

Leave optional limits empty to disable them. Use stricter limits when you see repeated checkout abuse or bot-created invoices.

Crypto checkout settings

If your store has crypto wallets enabled, extra settings can appear:

1. Underpaid Percentage for the allowed underpayment threshold.
2. Minimum Confirmations for the number of block confirmations required before an order processes.

Use these settings carefully because they affect when crypto orders move forward to delivery.
