Sylius Standard is free to use under the MIT licence. You still pay for development, hosting and maintenance, and those are often the larger costs of an online shop.

How much does Sylius Plus cost?

Sylius states that pricing starts from 800 euros a year. The real amount depends on your online sales volume and the modules you choose, so you have to ask for a quote.

Can I buy one Plus module on its own?

Yes. Sylius sells modules individually as well as the full package, so you can check whether a single module such as Request for Quotation covers your gap.

Can I start on Standard and move to Plus later?

Sylius mentions upgrades from Standard as a pricing factor, which shows the path is expected. Check module compatibility with your exact version before you plan around it.

Do Plus modules run on Sylius 2.3?

At the time of writing, the listings I checked name versions up to 2.2. Listings can lag behind releases, so ask Sylius for written confirmation for each module you need.

Sylius vs Sylius Plus: features, pricing and support

The difference between Sylius and Sylius Plus comes down to licence, modules and support. According to the official comparison, Sylius Standard is free under the MIT licence with community support, while Sylius Plus is a commercial licence starting from 800 euros a year, with SLA-backed support and paid modules for B2B, multi store and more. If you need few of these modules and have a developer, Standard is often enough. If you need several, price the licence against the cost of building them.

Sylius vs Sylius Plus at a glance

Item	Sylius Standard	Sylius Plus
Licence	MIT, open source	Commercial
Published price	Free	From 800 euros a year, then on quote
Support	Community	SLA-backed
Response time	No guarantee	1 day
Account contact	None	Dedicated Customer Success Manager

That table is based on the vendor's own page, so read it as a commercial presentation. An SLA, or service level agreement, is a contractual commitment on response. Check in your contract exactly what "1 day" covers, because a reply and a fix are not the same thing.

What the Plus modules add

The official page lists these modules: B2B Suite, Marketplace Suite, Advanced Multi-store, Returns Management, Multi-source Inventory, Loyalty System, role based access control, Partial Shipment, Request for Quotation, Product Configurator and Subscription. It also mentions advanced user permissions, admins per channel, multiple pricing lists, advanced search and one page checkout as features of the edition.

Translating this into business needs helps. Advanced Multi-store is about running several legal entities on one instance. Multi-source Inventory is for stock held in several places. Role based access control limits what each employee sees in the back office. Partial Shipment splits an order into several deliveries. If none of those sentences describes a problem you have today, you probably do not need them yet.

Multi store: do you really need Plus?

This question causes the most confusion. Sylius Standard already works with channels, and prices are stored per channel. So several shop fronts with different currencies or prices do not automatically require a licence. The Plus layer is relevant when you need more separation, such as several legal entities or admins restricted to their own channels. List your organisational constraints first, and then see whether they call for it.

How pricing works, and what it leaves out

Sylius explains that the full package is priced on your online gross merchandise value, the total value of your online sales. In a March 2024 article on its modular licence, it also lists factors such as geographic scale, B2C or B2B model, number of modules, and whether you are migrating or upgrading from Standard. That same article mentions monthly, yearly or lifetime payment. Since it dates from 2024, confirm those terms with Sylius.

So the 800 euro figure is an entry point and not a budget. The licence also does not include implementation. These figures are Sylius's published ones and have nothing to do with my own rates, which I give on request after looking at a project.

A simple way to decide

Your situation	Reasonable starting point
B2C shop, one company, specific logic that a developer can build	Standard
One precise gap, such as quotes	Price one module against custom development
B2B with organisations, price lists and quotes together	Ask for a Plus quote and compare
Several legal entities, large internal teams	Plus is worth serious evaluation
Need a vendor's contractual commitment	Plus, as a community forum cannot offer it

In every case, ask the following before signing. Is each module compatible with the version I will run? Listings such as the B2B Suite page name versions up to 2.2 at the time of writing, while Sylius 2.3 has been out since September. What happens to my shop if I stop paying? Can I see the source code of the modules, and can my own developer change them? What does a renewal cost when my sales grow, given that the price depends on them?

When neither edition is the right answer

Sylius is a framework for projects with specific needs and a developer to look after them. If you sell a simple catalogue, have no developer and want the lowest possible effort, a hosted platform is likely to serve you better, whichever edition you pick here. And if your project requires a large team, an agency listed in the official partner directory may be better suited. I am an independent developer and not a Sylius partner, and I earn my living building these shops, so bear that in mind when reading my advice.
