Build vs Buy App: Commission Custom or Use a Platform?

Most “build vs buy app” articles are written by someone selling one of the two. This one tries to answer the question you are actually costing: which option leaves you with the better app in three years, and what does each cost to get there?

Short version: buy more often than developers like to admit, but there are three constraints that flip the answer. Check those before you request a single quote.

Build vs buy app: when off-the-shelf is plainly the right answer

If your need matches a category that a mature platform already serves, take the platform. The clearest cases:

• Bookings, memberships and class schedules for a gym, clinic or studio.
• Online ordering and loyalty for hospitality and retail, where the platform plugs into your point of sale.
• Simple content or community apps that are mostly a branded wrapper around information you already publish.
• An internal tool for under about 50 staff where a no-code form-and-workflow product covers 90% of the process.

In these cases a platform gets you live in weeks, with payments, push notifications, app store submission and security patching handled for you. Typical costs run from roughly $50 to $500 a month for small teams, with setup of a few hundred to a few thousand dollars if you want it configured properly. Per-seat or per-order pricing can push that higher at scale, which matters later.

A custom build in the same category would cost 20 to 100 times the setup figure, and you would be rebuilding features the platform has already debugged. Nobody wins that trade.

When off-the-shelf quietly is not

The trouble is that platforms demo well. The first 80% of your requirements fit, and the remaining 20% turns out to be the part customers notice. Three constraints decide it.

Constraint 1: is the experience the product?

If customers choose you partly because of how the app works, you cannot rent that. A platform gives every competitor on it the same screens, the same flows and the same ceiling.

Ask: if a rival signed up to the same platform tomorrow, would they have your app? If yes, you are buying a commodity, and that is fine for a booking widget. It is a problem if the app is the thing you are charging for.

Constraint 2: does it need something the platform cannot reach?

This is where quiet failures live. Platforms are built around the common case, so they struggle with:

• Deep native capability: Bluetooth Low Energy peripherals, background location, HealthKit or Health Connect, on-device ML, offline-first sync.
• Integration with a system of record the platform has no connector for, such as an older ERP, a bespoke inventory system or an industry-specific API.
• Real-time behaviour: live tracking, collaborative editing, anything where “refreshes every few minutes” is not good enough.

A webhook and a Zapier step can cover a surprising amount. But if the integration is the heart of the app rather than a side feature, you will spend more working around the platform than you would building. If you are costing one out, this walks through what building an app actually involves.

Constraint 3: what does lock-in cost over three to five years?

Price the platform over the life of the app, not the first year. Check three things:

1. Pricing curve. Per-user or per-transaction pricing that is trivial at 200 users can exceed a custom build’s running costs at 20,000.
2. Data and export. Can you export your users, content and history in a usable format? If the answer is a vague “yes, on request”, treat it as a no.
3. Roadmap dependency. Your app gets only the features the vendor decides to ship, on their timeline.

Here is the whole test as code, because the logic really is this blunt:

Push notifications, real-time sync, and user data all need solid cloud backing. Cloud Geeks handles the server side so your app performs at its best.
