About this plugin
H6 Smart Checkout Fields lets you ask customers exactly what you need at checkout, without writing code. Add a gift message, a VAT number, a delivery date or an engraving name. Rename, reorder or hide the standard WooCommerce fields.
Charge for extras, choose which delivery dates customers can pick, and only ask a question when it applies to the order.
It is built for shop owners, not developers. The settings are written in plain English, every question has a short editor with the basics up front, and a “Try it out” tab shows you what a customer would be asked and charged before you go live.
Everything is included. There is no paid version and nothing is locked.
Good for:
- Gift messages, gift wrapping and personalisation
- Trade and wholesale details such as VAT numbers and purchase order numbers
- Delivery and collection dates, with the days you are closed ruled out
- Uploads such as artwork, proof of age or a purchase order
- Anything else you need to know before you can fulfil an order
Change the standard fields
- Rename any field and change the hint shown in the box
- Make fields required or optional
- Hide fields you do not need, such as the phone number
- Drag fields into the order you want
- Undo your changes and go back to WooCommerce’s own wording at any time
Ask your own questions
- Short and long answers, dropdown lists (with an optional pre-selected choice), pick-one buttons, pick several, lists of tick boxes and single tick boxes
- Email address, phone number, number, date, time, date and time, and colour
- File uploads, with the file types and size you choose
- Headings and notes to break up a long checkout
- A hidden value saved with every order, for your own records
- Full or half width, placed with the billing details, the delivery address or the order notes
Show a question only when it applies
- Based on another answer, such as “Is this a gift?”
- Based on the order: products or categories in the cart, the subtotal or the number of items
- Based on the customer: their customer type, such as trade customers
- Based on their choices: delivery method, payment method, billing or delivery country
- Questions appear and disappear on the checkout as the customer makes their choices
- The same rules can make a question compulsory only in some cases
Charge for an answer
- A set amount, a different price for each choice, an amount for every item, or a percentage of the subtotal
- Optional minimum and maximum charges
- Your own name for the charge in the order total, with or without tax
- The total updates as soon as the customer picks an option
- A hidden question never adds a charge
Check the answer
- Shortest and longest answer allowed
- Must match or differ from another answer, such as a “confirm email” box
- Must be a proper email address, or a number within a range
- Your own message if the check fails
Delivery and collection dates
- Set the earliest date customers can pick, such as at least 3 days away
- Set the latest date, such as up to 60 days ahead
- Close days of the week, such as weekends, and single dates, such as bank holidays
- Add a cut-off time, so orders placed after 2pm count from the next day
- The date picker greys out dates outside the range, and every date is checked again when the order is placed, in your shop’s time zone
Ask once per item, and group questions
- Ask a question once for every item or every product in the cart, such as a name to engrave on each item
- Group questions under their own heading in one of five places on the checkout, and show the whole group only when it applies
After the order
- Answers appear on the order screen, the thank-you page, the customer’s account and order emails, and you choose where
- Show any answer as a column in your orders list, and find orders by it
- Uploaded files are linked from the order
Move over from another plugin
- Import your questions from Flexible Checkout Fields, with a preview first and an undo afterwards
- Keep the original field names, so past and new orders share one name and exports, invoice templates and other plugins keep working
- Choose the field name prefix, or turn it off, and keep a field name exactly as another plugin expects it
- Leave off the checkout any field that another plugin adds, by listing its field name
- Old answers still show under a question’s new name, and can be copied across without deleting anything
- Save dates in the format your past orders use, such as 07.10.2026
Try it out and back up
- Describe an order and see which questions a customer would get, which they must answer and what they would pay
- Download a backup of your set-up, or move it from a test site to your live shop
