How Much Does It Cost to Build an App? The Honest Answer (And How to Get a Real Quote)
One developer quoted $3,000. Another quoted $20,000. Without a defined scope, both can be right. The cost variables explained, realistic Bubble.io build ranges for 2026, and why the Discovery Sprint is the only way to get a quote you can actually rely on.
Why Every Developer Quotes a Different Number
You have described your app idea to three developers. One quoted $3,000. One quoted $18,000. One quoted $75,000. All three say they can build exactly what you need. You have no idea which quote is accurate, and frankly neither do they — because without a defined scope, every developer is estimating a different product. The wildly different quotes are not a sign that developers are dishonest. They are a sign that your project does not yet have a definition that can be accurately costed.
The Variables That Determine Price
| Factor | Low End | High End | What Controls It |
|---|---|---|---|
| Feature count | 5-10 core features | 30-50 features | Scope discipline: what is MVP vs later |
| User roles | 1-2 roles | 5+ complex roles | How many different types of users and permissions |
| External integrations | 1-2 (email, payment) | 10+ (AI, maps, CRM, accounting, SMS) | Which third-party services the app connects to |
| Data complexity | Simple flat records | Complex relational model with denormalisation | How interconnected the data types are |
| Billing model | Simple checkout | Complex marketplace with Stripe Connect | One-sided vs two-sided payment flow |
| Mobile requirement | Responsive web only | Native iOS and Android | Whether App Store distribution is needed |
What Bubble.io Projects Actually Cost
| App Type | Complexity | SA Build Range | Timeline |
|---|---|---|---|
| Simple single-feature web app | Low | $2,500 – $4,000 | 3-4 weeks |
| Standard SaaS with auth, workspace, billing | Medium | $4,000 – $8,000 | 5-7 weeks |
| Complex SaaS with AI, multiple integrations | Medium-High | $8,000 – $15,000 | 8-12 weeks |
| Two-sided marketplace with Stripe Connect | High | $12,000 – $25,000 | 10-16 weeks |
| Full-cycle web + mobile app | High | $14,000 – $35,000 | 12-20 weeks |
These ranges assume correct architecture from day one: proper privacy rules, webhook-based Stripe billing, denormalised performance patterns, and full documentation. Apps built without architectural discipline may cost less initially and significantly more to fix later.
The Only Way to Know What Your App Will Cost
The Discovery Sprint is a 24-48 hour engagement where Athar Ahmad studies your idea, maps your user flows, designs your Bubble.io architecture, and produces a complete Product Requirements Document — including a precise, scope-based cost estimate and timeline.
Get a Precise Cost Estimate in 48 Hours
Stop guessing. The Discovery Sprint ($345) produces a full product blueprint with a fixed-scope cost estimate. Know exactly what you are building and exactly what it will cost before spending a dollar on development.
Everything You Need Before Committing to a Build
- Product Requirements Document (your full product blueprint as a structured PDF)
- Complete feature scope: every feature categorised into MVP (build now) and Post-MVP (build later)
- User flow diagrams: step-by-step maps of how users move through every core feature
- Bubble.io architecture plan: database structure, workflows, plugins, and API integrations
- Precise cost estimate: a fixed-scope range (e.g. $4,200-$5,800) based on actual complexity
- Realistic build timeline: week-by-week delivery plan
- 45-minute PRD Review Call with Athar: walk through the entire document together
- Full $345 credited toward your build if you proceed with SA Solutions
Q: Can’t I just describe my idea and get a quote?
A quote without a scope is a guess. We have seen developers quote the same project at $2,000 and $20,000 based on the same verbal description. The Discovery Sprint exists to eliminate this uncertainty.
Q: What if my idea is not fully formed?
That is precisely what the Discovery Sprint is for. You need a clear problem and a target user. Athar will structure everything else from there.
Q: What if I want to get a quote from multiple developers?
The PRD you receive from the Discovery Sprint is yours to share with any developer. A structured scope document is exactly what any developer needs to quote accurately.
