What it does
Checkout Guard blocks spam orders, fake orders, and the customers you already know cause trouble. Add an email, a first name, a last name, or any combination, and Checkout Guard denies the order the moment that customer tries to check out. No payment is attempted. No order is created. Your store stays clean.
Most WooCommerce fraud prevention plugins are built for risk scoring at scale. They run IP lookups, call external APIs, and ask you to configure rules. That is overkill when the real problem is one chargeback abuser, one wave of fake orders from a bogus address pattern, or one customer support has flagged twice already. Checkout Guard is the tool for that job. Block a customer, write a note about why, and move on.
It was built internally for the Visser Labs store and is now packaged as a standalone plugin. The plugin behind it has been load-tested against the same WooCommerce checkout flow our team uses every day.
Common use cases
Five scenarios where a simple block list beats a full fraud-prevention stack.
A buyer who has filed a chargeback or abused refunds once will often try again. Block their email and they cannot place a new order.
When one email pattern or name is hitting your store with bogus orders, add it to Checkout Guard and stop the loop before it costs you in failed-payment fees.
Mismatched billing and shipping, addresses that fail validation, names that do not match the country. Block the customer and move on with your day.
Abusive, threatening, or repeatedly fraudulent buyers. Add them to Checkout Guard once and they cannot order from you again.
Keep test buyers and internal staff orders off your live order count and reporting. Block their email during testing, remove it later if you want.
Checkout Guard is built for the times you just need to stop one specific person from ordering.
How it helps
A focused toolset that does one job, with nothing extra to configure.
Add an email address, a first name, a last name, or any combination. Either field is enough. The order is denied the moment that customer reaches checkout, logged in or as a guest.
You write the denial message shown at checkout. Keep it neutral or keep it firm. Your store, your wording. The block happens before payment is attempted, so it works with every gateway you run.
Add, edit, and remove blocked entries from a single screen under WooCommerce. Leave an internal note on each one so you, or your team, remember exactly why, even months later.
How it works
No setup wizard. No rules to configure. The whole plugin is about adding entries to a list.
Upload the plugin to your WooCommerce store, activate it, and paste your license key. You will see a new Checkout Guard menu under WooCommerce.
Enter an email address, a first name, a last name, or any combination. Add an internal note so you remember the context. Save.
That customer cannot place an order. They see the custom denial message you set. No payment is attempted, no order is created.
