Composite Products turns a WooCommerce product into a guided build: pick a frame, pick a lens, pick a strap, see one price. It is one of the more powerful things you can do with WooCommerce, and it is also one of the harder things to get right across currencies, because the final price is assembled from parts rather than stored as a number.

This review is more cautious than most in this series, and deliberately so. Composite Products and the Aelia Currency Switcher for WooCommerce do work together, but the mechanism that makes them work is a patch rather than a supported hook, and you should know that before you build a store on it.

What WooCommerce Composite Products Does

Composite Products lets you define a product as a set of components, attach a selection of real products to each component, and let the customer configure their way through them. It sells on the official WooCommerce marketplace at $112.00 per year for a single site, which makes it one of the pricier extensions in the catalogue.

It suits stores where the customer is genuinely specifying something rather than picking a variation: bicycles, PCs, furniture, hampers, made-to-order equipment. The pricing model is the part that matters here.

Where Composite Products Falls Short on International Stores

The compatibility note in Aelia’s own records is blunt about the cause: Composite Products lacks multi-currency support, and the Aelia patch covers that gap rather than the plugin handling it natively.

Two symptoms follow from that. The first is rounding drift. If each component is converted and rounded on its own, five components can each gain or lose a penny, and the displayed total will not match the sum of the lines the customer can see. On a £1,200.00 bicycle build nobody notices a penny; on a hamper of twelve items priced to the penny, somebody always does.

The second is configuration-dependent behaviour. A composite whose components are all simple products usually converts cleanly. Introduce variable products, per-component fixed adjustments, or a component whose price comes from another extension, and each of those paths has to be converted too. This is why “it worked in testing” is not the same as “it works”, and why the test that matters is a full configuration rather than the default one.

Rounding Drift on a Composite Product, in Numbers

This is the failure that generates support tickets, so it is worth seeing the arithmetic. A five-component hamper, priced from components, at 1.15 euros to the pound.

In this case the two approaches happen to agree. Change one component price by a penny and they stop agreeing, and the customer sees a total that is one or two cents away from the sum of the lines printed directly above it. Nobody loses money over two cents. What you lose is the customer’s confidence in the page, and that is harder to win back than the cents are to recover.

There are only two robust answers. Round once, at the composite total, and let the component lines be display values. Or use a fixed composite price so there is nothing to sum in the first place. The second is stronger, and it is the configuration worth arguing for whenever the catalogue can accommodate it.

The Compatibility Position, Stated Plainly

It is worth being clear about how this differs from the rest of the range, because the difference is the whole point of reading a compatibility note rather than a tick in a table.

Composite Products and Product Bundles sit in the same category, and for the same underlying reason: the plugin itself is not currency-aware, so something external has to stand in until it is. The durable fix is upstream, in Composite Products.

How to Set Up Composite Products With Multi-Currency Safely

Which Aelia Plugins Fit a Composite Products Store

The Prices by Country caveat carries extra weight on a composite store. Both the composite pricing engine and Prices by Country influence the product price, so on a component-calculated composite you have two systems writing to the same value. That combination needs proving on staging, not assuming.

What to Check After a Composite Products Update

Because the compatibility rests on a patch, updates are the risk point. This is the routine worth adding to your release process, and it takes about ten minutes.

Run this on staging with the most complex composite in your catalogue before the update reaches production. If a check fails, hold the update and raise it with Aelia support rather than patching it yourself, because the patch is maintained centrally and a local edit will be overwritten by the next Currency Switcher release.

When Composite Products Is the Wrong Tool

Worth saying, because $112.00 per year plus a moderate update risk is not the right answer to every configuration problem.

If the customer is genuinely specifying a build, Composite Products earns its price. If they are picking one of three finishes, you are buying complexity you do not need, and the multi-currency risk comes along with it.

Frequently Asked Questions About Composite Products and Multi-Currency

Sell Configured Products in Multiple Currencies

Composite stores tend to carry high order values, which is exactly why a rounding drift or a currency mismatch costs more here than elsewhere. Test the combination properly and it runs quietly for years.

Keep Reading on Assembled Products and Currency

Most WooCommerce store owners do not set out to compare multi-currency plugins. They set out to stop losing cross-border sales, notice that the checkout still charges in pounds when the shopper is in Germany, and end up on a plugin directory with four tabs open and no way to tell the options apart. The feature lists all look the same. The prices do not.

This is a side-by-side test of the three options that come up most often: the Aelia Currency Switcher for WooCommerce, CURCY by VillaTheme, and the multi-currency feature built into WPML’s WooCommerce Multilingual. Diego has maintained the Aelia Currency Switcher since 2013, so read the section on where Aelia is the wrong choice before you buy anything.

What a WooCommerce Multi Currency Plugin Actually Has to Do

WooCommerce ships with one currency. That is the whole of it. You set a currency in the settings, every price is stored against it, and every gateway is handed that figure at checkout. A multi-currency plugin has to bolt four separate jobs onto that single-currency foundation, and the plugins differ far more in the last two jobs than the first two.

Job one is a presentation problem. Job four is an accounting problem. A plugin that is excellent at the first and vague about the fourth will look fine in a demo and cause monthly reconciliation arguments a year later. If you want the underlying mechanics rather than a product comparison, the complete WooCommerce multi-currency guide covers how conversion, rounding and gateway handling actually work.

Aelia Currency Switcher for WooCommerce: What the £89.00 Buys

The Aelia Currency Switcher lets a store hold real prices in several currencies at once, rather than displaying a converted version of one price. You can let it convert automatically from a rate provider, or type the exact figure you want charged in each currency, per product. Version 4.15 is current, the plugin has been in continuous release since 2013, and it holds a 4.94 average from 91 customer reviews.

It costs £89.00 ex. VAT per year for a single site. There is no free tier.

Being plain about the limits, because they matter more than the feature list. The Currency Switcher is not a translation plugin and never will be; if you need multilingual content you still need WPML or an equivalent. It does not set different prices per country on its own either, which is a genuinely different job handled by Prices by Country. And there is no free version, so if your requirement really is display-only, you would be paying for capability you will not use.

CURCY Multi Currency for WooCommerce: The Free Route

CURCY, published by VillaTheme as “Multi Currency for WooCommerce”, is the most widely used free option in this comparison after WPML’s. It runs on 20,000 active installations with a 4.3 out of 5 average from 226 reviews. Version 2.2.16 arrived in August 2026 and is tested to WordPress 7.1, so it is actively maintained rather than abandoned.

The free tier covers the first two jobs properly: it adds a currency switcher as a widget, block or shortcode, converts prices from a rate provider, detects the visitor’s country to pick an opening currency, and lets you control the price format and symbol position. For a store that wants shoppers to browse comfortably and is content to settle every order in the base currency, that is a complete answer at zero cost.

The premium version adds checkout in the selected currency, per-currency payment method control and fixed per-currency pricing. The honest summary is that CURCY Premium and the Aelia Currency Switcher overlap substantially on paper. Where they differ is depth on the awkward cases: extension product types such as subscriptions, bookings, composite and bundled products, where prices are assembled from several components and each component has to convert correctly.

WPML Multi Currency (WCML): Multilingual First, Currency Second

WPML Multilingual and Multicurrency for WooCommerce, usually shortened to WCML, is the largest of the three by adoption: 100,000 active installations and a 4.2 out of 5 from 454 reviews, with version 5.5.7 current. The plugin itself is free but useless alone, because it requires a paid WPML licence to function.

Its multi-currency feature is genuinely capable. It supports manual prices per currency as well as automatic conversion, offers a currency switcher as widget, block or shortcode, shows different payment gateways per currency, and auto-switches based on visitor location. WPML also recommends manual prices per currency rather than live conversion, for exactly the reason Aelia does, which is that customers expect clean numbers.

The catch with WCML is not the feature set, it is the dependency. You are adopting a full multilingual stack to get a currency feature. If the store is already on WPML, that is free capability you have paid for and should use. If it is a single-language store, WPML is a large amount of machinery to install for currency alone.

Side by Side: Currency Switcher for WooCommerce Feature Comparison

Read that table as three different shapes rather than three scores. CURCY is the cheapest way to solve display. WPML is the obvious choice if you are already multilingual. Aelia is the one built for the money layer, and it expects you to bring your own translation plugin.

Exchange Rate Conversion vs Manual Prices per Currency

This is the decision that matters most and the one most store owners make by accident. Automatic conversion takes your base price, applies today’s rate, and shows the result. Manual per-currency pricing means you decide the number in each currency and it stays there until you change it.

Automatic conversion is correct for large, fast-moving catalogues where nobody could realistically maintain thousands of per-currency figures. It is wrong for considered purchases, because it produces prices like 103,47 € that read as careless, and because your margin moves every day without you deciding that it should. A 4% swing in sterling against the euro is a 4% swing in your gross margin on every euro order.

How Automatic Currency Detection Works in WooCommerce

All three plugins can open the store in a currency that matches the visitor rather than waiting to be asked, and all three do it the same way: read the visitor’s IP address, look it up against a GeoIP database, map the country to a currency. The differences are in what happens next.

Three practical points. First, geolocation and page caching fight each other, because a cached page is by definition the same for everyone; if your first visitor from Berlin warms the cache in euros, the next visitor from Leeds may get euros too. Aelia’s approach is a dedicated cache handler and per-currency cache variants, and this is the single most common cause of “the currency is wrong” reports on any plugin.

Second, detection should be a default and not a cage. The shopper must always be able to override it, and the choice must survive across pages. Third, a shared GeoIP library can collide: geo-blocking plugins such as Geo Redirect and iQ Block Country load the same library, and loading it twice crashes the request unless the Currency Switcher loads second. If you run a geo-blocking plugin alongside a currency plugin, test that combination specifically.

Payment Gateways, Subscriptions and Bookings in Multiple Currencies

This is job four, and it is where a comparison stops being about features and starts being about whether your accounts reconcile.

Gateways. Not every gateway accepts every currency, and those that do will often convert for you at a rate you did not choose, then charge a fee for the privilege. Showing a gateway that cannot settle the selected currency produces a failed payment at the last step, which is the most expensive place to fail. All three plugins can hide gateways per currency. Aelia goes further with multi-account routing, via the Aelia Currency Switcher and the PayPal Multi-Account gateway at £39.00 ex. VAT, so euro takings land in a euro account.

Subscriptions. A subscription signed in euros must renew in euros in 2029, at the agreed figure, regardless of where the exchange rate has gone or which currency the customer’s browser suggests today. Aelia handles this through the free Subscriptions Integration add-on, which requires Currency Switcher 3.3.11 or later; WPML supports it natively; CURCY’s coverage is thinner. If you sell subscriptions across borders, test a renewal on staging before you commit, because this is the failure that surfaces a month after launch rather than on day one.

Bookings and assembled products. Bookings, composite products and bundles build a price from parts: a nightly rate, an extra person, a chosen add-on. Each component has to convert, and the rounding has to happen once at the end rather than on every component, or the total will not match the sum of the lines. Aelia supports these through free integration add-ons rather than core, so the install order matters: activate both plugins first, then the add-on.

Common WooCommerce Multi Currency Pitfalls, and Which Plugin Avoids Them

The last row is the one worth reading twice. Most “multi-currency is broken” tickets are not a plugin defect, they are two plugins competing for the same job. Currency belongs to exactly one plugin on any store.

Which WooCommerce Multi Currency Plugin Should You Choose?

What Aelia Customers Say About the Currency Switcher

The Currency Switcher holds a 4.94 average from 91 reviews, and that support point comes up more often than any single feature. It is worth weighing when you compare a paid plugin against a free one: with the free options, your escalation path is a public forum thread. You can read more in our customer testimonials.

Frequently Asked Questions About WooCommerce Multi Currency Plugins

Try the Aelia Currency Switcher for WooCommerce

If the decision tree pointed at Aelia, you can test it against your own catalogue rather than a demo store. As the WooCommerce internationalisation experts, we would rather you found the edge cases during a trial than after launch.

Keep Reading on WooCommerce Multi Currency

Quantity breaks, category discounts and role-based pricing are the standard tools for shifting more units per order, and Dynamic Pricing has been the established WooCommerce option for them for years. On a single-currency store the rules behave exactly as configured.

Add a second currency and one class of rule quietly stops making sense. This review covers what Dynamic Pricing does, precisely where the multi-currency boundary sits, and how the Aelia stack handles it.

What Dynamic Pricing Does

Dynamic Pricing applies automatic price adjustments based on rules rather than coupon codes. It is published by Element Stark and sold through the WooCommerce marketplace, currently at version 3.4.15, priced at £97 per year on the one-year plan.

The mechanism is a rules engine that evaluates the basket and adjusts prices before totals are calculated. Because it works on rules rather than codes, the customer does not have to do anything, and the discount appears as part of the price rather than as a line-item deduction.

It suits a merchant selling in volume where order size is the lever: trade and wholesale accounts, consumables bought in multiples, or a catalogue where category-wide promotions run regularly. The role-based pricing feature also makes it a common choice for stores serving both retail and trade customers from one catalogue.

Key Features

• Advanced product pricing, configuring a table of quantities and matching discount amounts for each individual product.
• Advanced category pricing, applying tiered discounts across a whole product category based on purchase quantity.
• Simple category pricing, setting one fixed or percentage adjustment for every item in a category.
• Simple role-based pricing, discounting the whole catalogue for users in roles you define, such as trade or member accounts.
• Fixed or percentage adjustments, chosen per rule rather than globally.
• Automatic application, evaluating rules against the basket without the customer entering a code.
• Vendor terms, including product updates, support and a 30-day money-back guarantee.

Where Dynamic Pricing Falls Short on International Stores

The gap is multi-currency, and unlike some integrations it splits cleanly along one line: whether your rule is a percentage or a fixed amount.

Percentage rules are currency-agnostic. Ten percent off is ten percent off whether the price is in pounds, euros or yen, so these rules survive a currency switch intact.

Fixed-amount rules are not. A rule that takes 10.00 off is stored as the number 10 in your base currency. Switch the customer to a currency where the base unit is worth considerably less and that same 10 becomes a materially different discount. At best the margin is wrong; at worst a low-value order can be discounted close to nothing or below cost.

As with any third-party pricing plugin, this is a boundary rather than a defect. Dynamic Pricing controls its own discount logic, and multi-currency awareness has to be built by whoever owns that logic. Aelia’s addon reaches what it can from outside, and the following section is explicit about what it cannot.

How Aelia Fits With Dynamic Pricing

Compatibility Status

Aelia Currency Switcher

Status: fully tested with Dynamic Pricing.

The Currency Switcher handles pricing and payment in multiple currencies, refreshing rates automatically from providers including Open Exchange Rates and OFX, and storing the applied rate against each order. With the free integration addon active, discounts entered in your base currency are converted into the active currency, which fixes the fixed-amount problem described above. Read more on the Currency Switcher product page, £89.00 ex. VAT.

Aelia Prices by Country

Status: not separately tested. Prices by Country also adjusts product prices, so on a store where Dynamic Pricing controls discounting the two can overlap. Verify the interaction on staging before going live.

As a capability, Prices by Country reads the visitor’s country by geolocation and substitutes a deliberately set regional price rather than a converted one. This is the honest answer to the per-currency discount limitation: rather than trying to vary the discount by market, vary the price by market and keep the discount as a percentage. Because both plugins write to the product price, treat this as a combination to test, not a documented integration. Read more on the Prices by Country product page, £69.00 ex. VAT.

Aelia Tax Display by Country

Status: no known issues. Operates on tax display, a separate layer from Dynamic Pricing.

Tax Display by Country shows prices with or without tax depending on the visitor’s country, resolved by IP geolocation. It matters here because trade customers on role-based pricing usually want ex-VAT figures while consumers expect inclusive ones, and that is a display decision rather than a discount one. It should run alongside Dynamic Pricing without conflict. Read more on the Tax Display by Country product page, £69.00 ex. VAT.

Stack Recommendation

For a store running trade and retail pricing across several currencies, run Dynamic Pricing plus the Currency Switcher plus the free integration addon, keep your rules percentage-based wherever possible, and add Tax Display by Country so trade accounts see ex-VAT pricing.

Setup Notes

Install order matters, because the addon looks for both plugins when it activates.

1. Install the free Aelia Foundation Classes (AFC), version 1.8.3.170202 or newer.
2. Install and activate the Aelia Currency Switcher, version 4.4.6.170120 or newer, and set your base currency first.
3. Install and activate Dynamic Pricing.
4. Install and activate the free Dynamic Pricing Integration for Currency Switcher addon last. It needs no configuration.

Three things to check afterwards. First, audit your existing rules and note which are fixed-amount and which are percentage; the fixed ones are the only ones that depend on the addon behaving correctly. Second, confirm your base currency before writing rules, because every fixed amount is expressed in it. Third, test a rule at a tier boundary in a non-base currency, since rounding after conversion can move an order across a quantity threshold in ways a single-currency test never reveals.

What Aelia Customers Say

Worth knowing because integrations between plugins from different vendors are exactly where turnaround time matters. The free addons do not include support, but the Currency Switcher licence does.

FAQ

Does Dynamic Pricing Work With Multi-Currency Out of the Box?

Partly. Percentage-based rules translate across currencies without any extra work, because a percentage is currency-agnostic. Fixed-amount rules do not: the amount is stored in your base currency and is not converted, so it becomes a different real discount in every other currency. The free Aelia integration addon converts them.

Do I Need the Free Integration Addon?

If you use any fixed-amount discount rules on a multi-currency store, yes. If every rule you run is a percentage, the addon matters less, though installing it is harmless and protects you the first time somebody adds a fixed-amount rule. It is free, needs no configuration, and should be activated after both other plugins.

Can I Set a Different Discount for Each Currency?

No, and this is the one limitation that cannot be worked around externally. Dynamic Pricing’s interface does not provide per-currency discount fields, and adding them would mean modifying the plugin itself. The practical alternative is to keep discounts as percentages and vary the underlying price per market using Prices by Country instead.

Can I Set Different Prices per Country Rather Than Discounts?

Yes, and for international stores it is often the better structure. Our comparison of regional pricing versus multi-currency explains when a chosen per-country price beats a converted one, and how the two layers stack.

What Happens to Tax When the Currency Changes?

Tax is calculated on the discounted, converted price, so the rate applies as normal. Whether that price is shown inclusive or exclusive of tax by country is a separate presentation decision, handled by Tax Display by Country. If you sell into the EU, our guide to WooCommerce EU VAT compliance covers the rules that sit behind it.
