Pricing · Bubble.io Development
Four things decide what your Bubble.io app costs. Know them and you can estimate your own project, trim it wisely and recognise a quote that does not add up.
“How much does an app cost?” is the first question founders ask and the hardest for most agencies to answer honestly. The truthful reply is that it depends, but it depends on four specific things, and once you understand them you can estimate your own project and spot a quote that does not add up.
At Simple Automation Solutions, web and mobile builds in Bubble.io start at $3,500, with the final quote based on the scope in your PRD. Here is what sits behind that number.
What a build includes
- Full database and workflow build.
- Responsive UI and UX implementation.
- API and third-party integrations.
- Testing and launch-ready delivery, on your own domain or in the app stores.
In other words, a working product that real customers can use, not a prototype.
The four things that move the price
1. The number of user flows
A user flow is one distinct thing a person can do: register, submit a request, approve a document, book an appointment, pay. Each flow needs screens, data, rules and testing. A product with five flows is a very different project from one with thirty.
How to lower it: ship the three to five flows that deliver the core value first. Our guide to MVP feature prioritisation shows how to decide what to cut.
2. Integrations
Every payment gateway, email service, calendar, accounting tool or AI service has to be connected, configured and tested, including the edge cases when it fails. Integrations are a common source of hidden cost because founders forget to list them.
How to lower it: separate essential integrations from nice-to-haves. Launch with the essentials and add the rest after you have real users.
3. Web, mobile, or both
A web app and a native mobile app are separate builds with separate interfaces, even when they share the same Bubble backend. Building both costs more than building one.
How to lower it: start on the platform where your users actually are. Many B2B products, such as client portals and internal tools, work well as a responsive web app first.
4. Data complexity
How your information is structured and connected determines how much logic the app needs and how well it performs. A simple list of records is cheap. Multiple user types, shared accounts, approval chains and reporting across many linked data types are not. Getting this wrong is also the most expensive mistake to fix later. See database design mistakes that break apps at scale.
How to lower it: keep the first data model as simple as the business allows, and design it properly before building.
How the four factors combine
| Factor | Smaller scope | Larger scope |
|---|---|---|
| User flows | A handful of core flows | Many flows across several user types |
| Integrations | One or two essentials | Several services, some with complex logic |
| Platform | One web app | Web app plus iOS and Android |
| Data | Few, simple data types | Many linked data types, roles and reports |
Most real projects sit somewhere in between, which is why we quote from a written scope instead of a rate card.
Costs beyond the build
A fair budget includes more than the initial development.
- Bubble plan and workload units. Bubble charges for hosting and usage separately. Our guide to workload units explains how this is calculated and controlled.
- Ongoing support. After launch, improvements and fixes are billed from $35 per hour, only for the hours actually spent, with no retainers and no minimums. See keeping your app running after launch.
- Third-party subscriptions. Payment fees, email services or AI usage are paid to those providers.
How to read a quote
Whatever agency you talk to, a trustworthy quote should have these qualities.
- It is built from a written scope, ideally a PRD, not from a conversation alone.
- It lists what is included and what is not.
- It states how changes are handled.
- It separates build cost from ongoing platform and support costs.
- It explains the assumptions behind the number.
The cheapest way to get an accurate number
The most reliable way to get a real price is to define the scope first. Our Discovery Sprint costs $345, is delivered in 24 hours, and produces the PRD, architecture and cost estimate that the final quote is based on. If you then build with us, the $345 is credited toward the build.

Frequently asked questions
Why does the price start at $3,500?
That is the starting point for a scoped, launch-ready Bubble.io app: database, workflows, responsive UI, integrations and testing. Below that level, you are typically getting a prototype rather than a product.
Is the price fixed?
The final quote depends on the scope in your PRD. Once scope is agreed, the number is based on it, and changes are handled deliberately rather than informally.
Does mobile cost more than web?
Yes. Web and mobile are separate builds even when they share a backend, so building both costs more than one.
What does support cost after launch?
From $35 per hour, billed only for hours spent, with no retainers or minimums.
