TL;DR:<\/strong><\/p>\n Think of a marketplace like a hypermarket. Your service sits on a shelf next to a dozen competitors, and the hypermarket, not you, decides who sees it, who gets the loyalty card and who keeps the receipt. That is the real trade-off.<\/p>\n The biggest issue is client ownership<\/strong>. Marketplaces typically mediate contact between you and the client, so the client\u2019s phone number, email and appointment history often sit in the platform\u2019s database rather than yours. You can\u2019t invite back someone whose contact details you never received.<\/p>\n Then there is margin. Fee models differ between platforms and change over time, so check the current price list of the platform you are considering rather than relying on averages. Whatever the model, a fee that also applies to repeat appointments made through the platform keeps costing you every time the same client returns, and side-by-side listings put your prices right next to your competitors\u2019 prices.<\/p>\n Platform terms can also give the operator broad rights to use listing content and client information for its own advertising or other commercial purposes. In the EU, the platform has to describe its access to that data in its terms (more on that below), so read that part closely before you sign.<\/p>\n Other issues to plan for:<\/p>\n None of this means marketplaces are worthless. It means they need guardrails.<\/p>\n The legal picture is more nuanced than \u201cthe platform handles compliance, so you don\u2019t have to\u201d. Under the GDPR (Regulation 2016\/679), whoever determines the purposes and means of processing personal data is a controller (Article 4(7)). Whether a marketplace acts only on your behalf, as your processor, or as a controller in its own right changes what it may do with your clients\u2019 information.<\/p>\n In Russmedia (C-492\/23, judgment of 2 December 2025), the Grand Chamber of the Court of Justice of the EU looked at a classified-ads marketplace whose terms let it copy, distribute, modify and pass on published content. The Court held that the operator was a controller of the personal data in those ads, because it could exploit them for its own advertising and commercial purposes, and noted that a platform\u2019s terms of use can be evidence of decisive influence over the processing. The case was about classified ads, not appointments, but the lesson carries over: a platform is not automatically a neutral intermediary, and its terms show what it can do with the data.<\/p>\n The Platform-to-Business (P2B) Regulation 2019\/1150, which has applied since 12 July 2020, adds transparency duties for online intermediation services that let businesses established in the EU offer goods or services to consumers in the EU, wherever the platform itself is based. A booking marketplace that lists your services and passes appointments to you generally fits that definition. Among other things, the platform must:<\/p>\n Transparency is not the same as protection. The Regulation makes platforms tell you the rules, but it doesn\u2019t oblige them to hand over client contact details, so the business decisions below still matter.<\/p>\n Before listing anywhere, check:<\/strong><\/p>\n Fees don\u2019t just dent this month\u2019s payout, they compound. A client you acquire through a marketplace and never get contact details for is likely to rebook there, and depending on the fee model you may pay again for that visit, because you have no direct way to bring them back yourself.<\/p>\n Reconciliation gets messier too. Payments, refunds and no-show charges often run through the marketplace\u2019s own ledger, which rarely lines up neatly with your own records, so month-end checks take longer.<\/p>\n The P2B Regulation gives you reasons and, for a full termination, 30 days\u2019 notice, but it doesn\u2019t guarantee you a copy of your clients\u2019 contact details. Treat a suspension or a platform shutdown as a business continuity risk, not just an inconvenience.<\/p>\n You don\u2019t need to choose between \u201call in\u201d and \u201call out\u201d. A structured approach gets you the reach without most of the downside.<\/p>\n On consent: under the ePrivacy Directive 2002\/58\/EC (Article 13), marketing by email \u2013 which in the Directive includes SMS \u2013 generally needs the client\u2019s prior consent. The exception for existing clients covers only your own similar services, and only if clients can object easily and free of charge when you collect their details and in every message. If the contact details reached you through a marketplace rather than from your own sale, that exception may not apply in the same way, so ask for consent at the first visit. National rules differ, so check yours.<\/p>\n Treat the pilot as a genuine test, not a formality. Fix the KPIs and the decision rule before the first appointment, then let the numbers decide.<\/p>\n A worked example with hypothetical figures, not any platform\u2019s actual fees: over 90 days a marketplace brings 40 net-new clients with an average first-visit bill of \u20ac55, which is \u20ac2,200. If the fee is \u20ac12 per new client, you pay \u20ac480 and keep \u20ac1,720, or \u20ac43 per client. By day 90, 14 of the 40 have booked their next visit directly with you (35%), 10 have rebooked through the marketplace (25%) and 16 haven\u2019t come back (40%).<\/p>\n Then compare. Is \u20ac12 per new client cheaper than what your other channels cost you per new client, and is the direct share growing? If the platform also charges for the 10 rebookings, add those fees to the cost side before you decide. If the numbers don\u2019t justify the fees once you factor in the clients you can\u2019t invite back, that\u2019s your answer.<\/p>\n If you run the pilot in Altegio, note one limit: the Appointments report splits appointments only into online and offline, so it can\u2019t tell you which ones came from a marketplace. A simple workaround is to add every marketplace client to a dedicated client category, for example \u201cMarketplace pilot\u201d, when you enter their first appointment. At day 90, filter the client base by that category and by number of appointments to see who came back, and use the Lost clients filter to find the ones worth inviting back \u2013 the lost-client period is a setting under Analytics > Settings > Client Churn. More on the reports in statistics and analytics<\/a>.<\/p>\n Before signing up, ask yourself:<\/p>\n Any \u201cno\u201d to the first three, or \u201cyes\u201d to the last, is a reason to pause before committing.<\/p>\n Your own booking system doesn\u2019t replace a marketplace\u2019s audience. What it gives you is a channel where the client relationship stays with you, so every client a marketplace brings can come back directly. In Altegio, software for appointment-based businesses such as beauty, wellness, clinics, auto services and fitness, that channel looks like this:<\/p>\n Altegio is a subscription: the price depends on the number of team members and the billing period (see pricing<\/a>). Altegio doesn\u2019t charge its own commission on online payments \u2013 only the payment provider\u2019s fees apply.<\/p>\n Two honest limits. The booking form has a mandatory personal-data consent checkbox but no marketing-consent checkbox, so record marketing consent separately; an opt-out is set manually in the client card. And your own channel doesn\u2019t bring a marketplace\u2019s audience by itself: new reach comes from Reserve with Google, social booking, your website and word of mouth.<\/p>\n To try it with your own data, start the 7-day free trial<\/a>. Moving your client base over is free.<\/p>\n Most advice on this topic focuses on reading the contract carefully, which is sound but incomplete. The bigger gap is not having your own place to keep client contact details at all, marketplace or not, so even a well-negotiated contract leaves you with nothing to fall back on when the platform changes its terms.<\/p>\n Marketplaces are usually treated as a reach problem. It is more useful to treat them as a data ownership problem first: reach without a way to invite people back is a rented audience, not a growing one.<\/p>\n If you only do one thing from this article, make it this: record every client\u2019s contact details in your own client base from the first visit, and ask for marketing consent separately, before you negotiate anything else. Loyalty programmes, pricing policy and pilot KPIs only work once that first connection is yours.<\/p>\n Not inherently, but they carry real trade-offs: weaker direct contact with clients, fees and possible use of client data by the platform. The risk is manageable with the right terms, a 90-day pilot and a parallel booking channel of your own.<\/p>\n It depends on the platform\u2019s terms and on its actual role. Under the GDPR, a platform that uses client data for its own purposes can be a controller in its own right \u2013 in C-492\/23 the Court of Justice treated a classified-ads marketplace that could exploit published data for its own commercial purposes in exactly that way. Check the data-access section that the P2B Regulation requires in the platform\u2019s terms.<\/p>\n Partly. It requires plain and intelligible terms, at least 15 days\u2019 notice of changes, reasons for restrictions and suspensions, 30 days\u2019 notice before a full termination and an internal complaint-handling system. It is mainly a transparency rule, though: it doesn\u2019t oblige a platform to hand over client contact details.<\/p>\n Record every client\u2019s contact details in your own client base from the first visit and ask for marketing consent separately. That single habit is what makes direct rebooking and loyalty programmes possible later.<\/p>\n It can take over booking, reminders, payments and loyalty without a fee to a platform for each appointment. It doesn\u2019t bring a marketplace\u2019s audience on its own, so pair it with Reserve with Google, social booking and your website, or keep a marketplace as one channel and measure it with a pilot.<\/p>\n This article is general information, not legal advice.
