WooCommerce checkout: what I look at before adding more plugins

Everything before the checkout is persuasion. The checkout itself is administration — and it is the only screen where a customer who has already decided to buy can still fail to. That asymmetry is why it deserves attention before anything else in a store.

1. Fields you do not use

The default WooCommerce billing form asks for a company name, a second address line, a country you may only ship to one of, and a postcode that a large share of Gulf addresses do not meaningfully have. Every field that is not used downstream is a decision cost with no return. Remove them at the template level rather than hiding them with CSS — a hidden required field is a checkout that fails silently.

2. The mobile keyboard

A phone number field that opens a full alphabetic keyboard, or an email field without the right input type, adds friction that nobody reports and everybody feels. Correct type, inputmode and autocomplete attributes cost nothing and are frequently missing after a theme has customised the form.

3. Arabic-specific checkout problems

• Phone numbers, prices and order numbers are Latin fragments inside an Arabic layout — they need isolation or they reorder the line around them.
• Address formats differ. A form designed around a street-number-first Western address does not fit how the address is actually written or spoken.
• Validation messages must align to the same edge as the field they describe, or the eye has to travel across the form to read them.
• The progress indicator has to advance toward the reading edge. An Arabic checkout that advances left reads as undoing itself.

4. Payment method presentation

Wallet payments such as Apple Pay only appear on supporting devices and browsers, which means the layout has to hold together both with and without them. A payment row designed around three visible options looks broken when the device shows one. Test on the device, not in a desktop browser.

5. Caching the uncacheable

6. What happens when it fails

Most checkout reviews test the successful path. The expensive path is the failed one: a declined card, a timed-out gateway, a validation error on the fourth field. Whether the customer's entered data survives that failure is the difference between a retry and an abandoned order.
