A free Product Add-Ons alternative, with sets you build once.
WooCommerce Product Add-Ons costs $79 a year and has no free version. AddOnBoss does the same jobs free, then keeps going: colour swatches, fields that appear only when needed, option sets reused across the shop, made-to-measure pricing by size, and a whole size run ordered in one grid.
From $89 a year · 30-day money-back · No card for the trial

Three that matter most.
Try it before you pay
Product Add-Ons is paid only. AddOnBoss has a complete free version, so you can add options and fees on a live product first and upgrade when it earns its keep.
Fields that appear when needed
Conditional options reveal a field only when its trigger is chosen, instead of showing every add-on at once. Product Add-Ons has no conditional logic.
Build a set once
Build Colours once and attach it to every product that needs it. Edit it in one place and every product follows, instead of keeping the same choices in step by hand.
Why shops choose AddOnBoss.
You can put it on a live product today without paying anything, and the free plugin already does what Product Add-Ons charges $79 a year for, plus colour swatches and fields that appear only when needed. When you grow, Pro adds per-letter pricing, artwork uploads with limits you set, made-to-measure pricing and a whole size run in one grid. Start with AddOnBoss free and build your first set today.
Common questions.
Is AddOnBoss a free alternative to WooCommerce Product Add-Ons?
Yes. AddOnBoss has a genuinely complete free version on WordPress.org that adds option sets, priced add-ons and text fields to any product. WooCommerce Product Add-Ons is a paid-only extension. Show-and-hide rules are free too. Pro adds per-letter pricing, file uploads and made-to-measure sizes when you are ready.
Can I move my existing add-ons across?
AddOnBoss is designed to cover the same jobs (gift wrapping, special messages, extra options and made-to-order fields) with correct pricing and tax. Rebuilding a set takes a few minutes per product, and once a set exists you attach it to the next product in a click.
Does AddOnBoss charge the right tax on add-on fees?
Yes. Every fee is added through WooCommerce’s own pricing and tax, so it is correct whether your prices are entered inclusive or exclusive of VAT. Totals do not drift between the product page, cart and order.
Build a set once, use it everywhere.
Free to start, correct in the cart, and it shares an engine with BundleBoss so bundles and options never fight.
