AddOnBoss adds extra product options, product add-ons and custom fields to a WooCommerce product page. Colour swatches, a dropdown of finishes, checkboxes for extras, a name to engrave, a gift message: each one can carry its own price, the total keeps up as the shopper chooses, and every answer lands on the order.
See how option sets replace variations:
Try it live: demo.bossmage.com is a full demo store running Pro. Put a name and number on a team kit, pick a colour and watch the photo change, order a whole size run in one grid. Click around and configure things, nothing breaks.
In the free plugin:
Reusable option sets. Build Colours once and attach it to any product, like global product options you edit in one place.
Swatches, buttons or a dropdown , where shoppers pick one or pick several.
Custom fields : text, a message, a number, a date, a time, a dropdown, a tick box, an email address and a colour.
Priced choices , taxed as part of the product and not as a surcharge.
Conditional logic : show or hide a set or a field from what the shopper picked or typed.
A price they choose , for donations, tips and name your price extras.
No variations needed. A product with five colours and five sizes would be twenty-five variations to build and maintain. Here it is one option set, attached in a click, and the product stays a single simple product. Your product editor stays fast, and adding a colour next month does not mean rebuilding every combination.
What you can sell with it
Personalised gifts. An engraved board with a finish to choose, a name to engrave and gift wrap as an optional extra, each carrying its own charge.
Food and drink. Choose up to three toppings, add a sauce, leave a note for the kitchen. Every pick keeps its own price.
Any shop with a variation problem. Five colours by five sizes offered as choices, instead of twenty-five variations to build and price. A made-to-order shop needs nothing else. A shop that counts stock on each colour and size wants Pro, where a single choice holds its own stock.
A sweet shop (Pro). Pick and mix by the choice, with a limit on how many, and any single flavour able to sell out on its own while the rest stay on sale.
A signage, framing or blinds shop (Pro). A price grid with width down one side and height across the other, or a rate per square metre applied to the exact size a customer types in.
A workwear or print shop (Pro). A whole size run ordered in one grid, priced down by quantity band, with the customer’s logo uploaded, checked for resolution before it reaches your printer, and drawn on your own product photo as they type.
What makes AddOnBoss different
A library, not a form on every product. Many plugins in this category have you build a form on each product, so the same five colours get rebuilt fifty times and adding a sixth means fifty edits. Here an option set is a thing in its own right. Build Colours once, attach it wherever it belongs, and editing it in one place updates every product using it. If one product cannot be had in two of those colours, tick them off for that product alone and the rest of the shop is unaffected.
The free plugin is a whole product, not a taste of one. Option sets, several-choice sets with bounds, fourteen field types, groups and the full cart and order path are all here, and every one of them charges and taxes correctly. Pro adds jobs the free plugin does not attempt, like artwork upload and made-to-measure pricing. It is not the same plugin with something switched off.
Pro handles the jobs that usually need a second plugin. Price by the square metre from the dimensions a customer types, or from a width-by-height grid, the way the made-to-measure trade writes its own price lists. Order a whole size run in one grid, every colour by every size, priced down by quantity band as the run grows. Hold stock on a single choice, so one flavour sells out on its own while the rest stay on sale. Take the customer’s artwork, check it is high enough resolution before it reaches your printer, and draw their name or logo onto your own product photo as they type.
One engine, two plugins. AddOnBoss and BundleBoss run the same options engine and share one option-set library. A Colour set you build in either one is ready in the other, with no export, no second copy to keep in step, and no double charging when both are active.
And the money is right. Every charge joins the cart line through WooCommerce’s own pricing and tax, so it is taxed exactly as the product is, in the basis your store displays, and it lands on the order as part of the line. It is never a surcharge bolted on after tax. Worth checking before you commit to any options plugin, because getting it wrong is invisible until an accountant finds it.
What the free plugin does
This is the whole options product for a simple product. Build a set once, attach it anywhere, and the choices are priced and taxed as part of the line.
Reusable option sets : define colours, sizes, finishes or weights once, attach them to any product, reorder and rename from one library. They show as swatches, buttons or a dropdown, and each choice can carry a charge.
Choose one or choose several : a set can let shoppers pick more than one choice, like choosing up to three toppings, with an optional “at least” and “up to” bound. Every pick keeps its own charge and each one reads separately in the cart and on the order.
Custom fields : a name to print, a message, a number, a date, a time, a dropdown, a tick box, an email address, a web address, a section label and an info block, each optional or required, each able to charge once or for each item.
A colour field : the colour they want you to use, picked from swatches you define, each with its own optional charge, or typed as any colour if you allow it. The order carries the colour name and code, and your order screen paints the swatch.
A price they choose : a field where the shopper enters an amount of their own, for donations, tips and pay-what-you-wish extras. You set the floor, the ceiling and a suggested figure, and one-tap suggested amounts fill the box.
A hidden note for your own orders : a value that rides on every order of the product, a production route or a supplier code, shown only on your order screen and never to the customer.
Long lists search themselves : past a dozen choices, any dropdown becomes a searchable list that filters as the shopper types, with unavailable choices shown but not pickable. Phones get the same control, sized for thumbs.
Groups : gather related options under their own headings, so a long list reads in sections instead of one run.
Rules that show and hide : show or hide a set or a field depending on what the shopper picked or typed, with “and” and “or” groups and no limit on how many rules.
Shoppers see what is left : an answered question gets a tick, a line under the total names what is still to choose, and Add to cart pressed too early names every unanswered question.
A product can refuse a choice : use one shared Colour set across the shop and tick off the two colours this particular product cannot be had in. The set stays one set, so a colour added to it later is offered everywhere it was not refused.
A correct cart and order path : options join the line through WooCommerce’s own pricing and tax, and the picks read on the order screen, in emails and on reorder.
Links that choose : add ?colour=white&size=m to a product’s address and the page opens with those choices made.
Part of the BossMage family
AddOnBoss is made by BossMage , alongside BundleBoss.
BundleBoss builds bundles, mix and match packs and build-your-own boxes. AddOnBoss puts options, add-ons and personalisation on a product’s own page. Either works alone, and running both gives you one option-set library: a Colour set built for a bundle is there for a simple product too, and the other way round.
If you run both, keep BundleBoss up to date: AddOnBoss waits, with a notice, beside a much older BundleBoss.
Guides and screenshots for every feature are at bossmage.com/docs/addonboss .
What AddOnBoss Pro adds
AddOnBoss Pro is a separate paid plugin. The Solo plan has a 14-day trial, no card needed. It adds:
Options on variable products , so a parent can offer sets alongside its own variations
A quantity grid : order a whole range at once, every colour by every size, as one order
Google Shopping for colour and size : a daily feed with an item per colour and size, each with its own photo, price and a link that opens it chosen
Quantity discounts : price breaks by how many they buy (10 to 24 pay one price, 25 to 49 a lower one), shown as a trade price table or a card ladder, counted across a whole size run
File and artwork upload , with a confined upload area, resolution checks before you print, and GDPR export and erase
Print areas and product sides , with the customer’s name or logo drawn on your own product photo as they type
Rules on numbers : reveal or hide a set or a field when an answer is more than, less than or exactly a number, on top of the show and hide rules every build has
Choices that can’t go together : in a pick-several set, group the choices that exclude each other, like print and embroidery on the same breast. A blocked choice greys out and says why, the till refuses the pair whatever a browser posts, and a choice like “no printing needed” can stand alone
Measured sizes : price by length, area or volume from the dimensions a customer types
Price tables : a grid of prices, width down one side and height across the other, with a minimum charge and an optional margin on a cost grid. Shoppers pick a size or type their own and the right cell prices it
Stock per option : hold a count on a single choice, so ten jars of one flavour sell out on their own while the rest stay on sale. Sales, cancels and restocked refunds keep the count, and nobody can order more than you have
Shop filters : your shop’s own filters (WooCommerce’s, WOOF, YITH and the rest) find a product by the colours and sizes chosen t

Gettingstarted.
01Upload the plugin to /wp-content/plugins/ or install it from the Plugins screen, and activate it.
02WooCommerce must be active.
03Open Products, edit any product, and use the Product Options panel to attach an option set or add fields.
04Build and reuse option sets from the Option Sets library in the menu.
If you also run BundleBoss, keep BundleBoss updated to a version that ships the shared engine before activating AddOnBoss. AddOnBoss detects an older BundleBoss and waits, with a notice, rather than risking a conflict; once BundleBoss is updated it switches on by itself.

Frequently asked questions.
Does AddOnBoss have conditional logic?
Yes, and it is in the free plugin. A set or a field can show or hide depending on what the shopper picked or typed earlier, such as a thread colour that only appears once embroidery is chosen. Rules can be grouped with “and” and “or”, and there is no limit on how many you write. Rules that compare a number (more than, less than, exactly) are in Pro.
Can I use it for personalised gifts and engraving?
Yes. Add a text field for the name or message, give it a charge if engraving costs extra, and add gift wrap as a tick box. The shopper personalises the product on its own page and what they typed reads on the order. If you write for an American audience: yes, this is product personalization, and customers can customize a product with color swatches, checkboxes and text fields.
Which field types are there?
Free: text, a longer message, a number, a date, a time, a dropdown, a tick box (checkbox), an email address, a web address, a colour, a price the shopper chooses, a hidden note, a section label and an info block. An option set shows as swatches, buttons (the job radio buttons usually do) or a dropdown. File upload, repeatable fields and per-letter pricing are in Pro.
How is this different from using a variable product?
A variable product creates a real variation for every combination, so five colours by five sizes is twenty-five things to create, price and keep in stock. An option set offers the same five colours as choices on the product page without generating anything, so the product stays one product. Use variations when each combination genuinely needs its own price, SKU and stock. Use option sets when they do not, which is most of the time.
How do I add options without creating variations?
Build an option set, for example a list of colours each with an optional charge, and attach it to any product from the Product Options panel. The product offers those choices on its page like a variable product would, but no variations are generated, so the product stays light and the editor stays fast.
Will it create dozens of variations?
No. That is the point. An option set offers the choices a variable product would without generating any variations, so a product with many colours and sizes stays a single light product.
Are the extra charges taxed correctly?
Yes. A charge joins the cart line through WooCommerce’s own pricing, so it is taxed exactly as the product is, in the same basis your store displays. Nothing is added as an untaxed surcharge, and this is true in the free plugin, not only in Pro.
Can I use the same option set on more than one product?
Yes, that is what the library is for. Build a Colour set once and attach it to as many products as you like. Edit it in one place and every product follows. If one product cannot be had in two of those colours, tick those choices off for that product and the rest of the shop is unaffected.
Do the customer’s choices show on the order?
Yes. Every pick and every typed answer reads on the order screen, in the order emails and on the customer’s account, and they survive a reorder. Whoever makes the thing sees what was asked for.
Why did the express payment buttons disappear from a product page?
On products with required options, including a required upload, AddOnBoss automatically hides Apple Pay, Google Pay and PayPal express buttons on the product page. Those buttons skip the option form, so the order would arrive without the answers you require. Products whose options are all optional keep their buttons (the Mollie and Amazon Pay buttons step back while an option is chosen), and express payment still appears in the cart and at checkout, where the chosen options are already included. It covers the major express providers; developers can override it per product with the addon_boss_allow_express_pay filter.
Do I need BundleBoss to use AddOnBoss?
No. AddOnBoss works entirely on its own. If BundleBoss is also installed, the two share one option-set library, so a set you build in one is available in the other. Each plugin runs its own engine and they are built to run side by side without conflict.
Does it work with variable products?
The free plugin puts option sets on simple products. Options alongside a variable product’s own variations are a Pro feature, because a page offering two choice systems at once has to reconcile them.
Will it slow my product page down?
Options are drawn by the plugin rather than generated as variations, so a product with fifty choices is still one product with one set of data behind it. There is no variation table to load and no combination matrix to build. A product with twelve option sets and two hundred and forty choices costs four database queries to draw, measured on every release.
Does it work with the block cart and checkout?
Yes. AddOnBoss declares compatibility with the block cart and checkout, and with WooCommerce High Performance Order Storage.
Can customers upload a logo or a file?
That is a Pro feature. With Pro, a file upload field lets the customer attach a logo or artwork, the file shows on the order for you to work from, and it is covered by WordPress’s personal-data export and erase tools. The free plugin has no upload field, so it never accepts or stores a customer file.
How do I price something by its size?
Two ways, and which one you want depends on how you sell. A price table is a grid: you type the price for each width and height, and a shopper who asks for something in between is priced from the band it falls in, which is how the made-to-measure trade prints its own price lists. Measured sizes work the other way round, as a measurement price calculator: a rate per square metre and the exact dimensions the customer types. Both are in Pro, and so are quantity discount bands.
Can one choice sell out while the others stay on sale?
In Pro, yes. Put a count on a single option and WooCommerce owns it from there, so ten jars of one flavour sell out on their own while every other flavour carries on. A sale takes it off, a refund puts it back, and a sold-out choice says so and cannot be picked.
What happens to my settings if I stop paying for Pro?
Nothing is deleted. Your option sets, fields, prices and configuration stay exactly where they are, and the free plugin keeps rendering and charging everything it can. The Pro-only behaviour stands down and waits, so if you come back later your setup is as you left it.
How long does setup take?
A couple of minutes. Open a product, use the Product Options panel, and attach a set or add a field. Building a reusable set the first time takes a little longer; after that you attach it in a click.
What is removed if I uninstall?
AddOnBoss removes its own settings and cached data, and nothing else. Your option-set library and the options attached to each product are your configuration, not ours, and BundleBoss may be sharing that same library, so uninstalling never touches them. Products and orders are WooCommerce data and are left alone, so the record of what a customer ordered stays intact. Reinstall later and your sets are as you left them. If you use Shop filters, switch it off before uninstalling to take its entries back out of your filters; an uninstall leaves them on your products like any other product data.
