WooCommerce Product Add-Ons Plugin
Smart Add-Ons — WooCommerce Product Add-Ons, personalized for every store
Smart Add-Ons is the WooCommerce product add-ons plugin for stores selling personalized, made-to-order products — engraving, gift wrap, custom sizing, print-on-demand.
Customers see a live price preview as they choose options, backed by conditional logic and secure file uploads, on a plugin built for WooCommerce Blocks and HPOS — not retrofitted onto them.
Licensed directly from the team that builds it, so you can try it on a live store before you buy.
- Blocks & HPOS Ready
- 30-Day Money-Back Guarantee
- GPL Licensed
- Direct Support from the Team That Builds It
Who it’s for
Built for the people who actually run WooCommerce stores
Whether you sell one-of-a-kind products, manage several sites, or build stores for clients — Smart Add-Ons fits how you already work.
See it in action
What your customers actually see
Not a mockup — this is Smart Add-Ons running on a real WooCommerce product page.
Visual options, not dropdowns
Customers pick a material, color, or style by sight, not by guessing from a list of text labels.
Secure uploads, right on the product page
Customers attach their own artwork or files before checkout — no separate email thread required.
Only the options that apply
Fields can appear or disappear automatically based on earlier choices, so customers never see add-ons that don’t apply to them.

Compare
Smart Add-Ons vs WooCommerce Product Add-Ons
Smart Add-Ons does the same core job as the official WooCommerce extension — product options and paid add-ons. The difference is everything built since: a plugin designed from the ground up for WooCommerce Blocks checkout, block themes, HPOS, and the growth tools modern WooCommerce stores are asking for.

Common questions
Frequently asked questions about Smart Add-Ons
Quick answers about compatibility, performance, licensing, and what happens if it’s not the right fit.
Does Smart Add-Ons work with WooCommerce Blocks and block themes?
Yes. Product options, cart, and checkout all work with WooCommerce Blocks and FSE block themes, not just the classic checkout — no separate compatibility patch required.
Will Smart Add-Ons slow down my store or conflict with other plugins?
Smart Add-Ons is built for WordPress 6.4+, PHP 8.1+, and WooCommerce 8.0+, and only loads its assets on pages where add-ons are active.
Can I show or hide options based on what a customer already chose?
Yes. Conditional logic lets you show, hide, or require fields and groups based on earlier selections, customer role, or a schedule — set up in the visual builder, no code required. Full details are in the documentation.
Can customers upload their own artwork, logos, or files?
Yes. Add a secure file-upload field to any product, set the file types and size limits you allow, and download what customers send you directly from the order in WooCommerce admin.
How many sites does one license cover, and can I move it later?
Starter covers 1 site, Pro covers 3, and Agency/Enterprise cover unlimited sites. You can deactivate a license on one site and activate it on another at any time.
What happens after my first year?
Your license keeps working after year one — plugin updates and support renew annually, but Smart Add-Ons doesn’t stop functioning on your store if you choose not to renew.
What if Smart Add-Ons doesn’t fit my store?
Every license includes a 30-day money-back guarantee, no conditions beyond a supported WordPress and WooCommerce setup. Support is also included if you need help before deciding.
Can I switch from WooCommerce Product Add-Ons without starting over?
You’ll need to rebuild your option groups in Smart Add-Ons’ builder — there’s no automatic importer today — but the visual builder and templates are designed to make that a fast, one-time setup rather than a rebuild from scratch.
