How much does it cost to build your app idea?
We get asked this all the time. The honest answer is "it depends," but we can give you a much better frame of reference than that. Here's what industrial-grade versions of well-known apps would actually cost to build from scratch.
Consumer Apps (B2C)
These are the apps everyone knows. We've estimated what an industrial-grade MVP would cost to build, not the billions in engineering that went in after launch.
Ride-hailing app
Mobile
Uber
Lyft
GrabThree separate interfaces (rider, driver, admin), live mapping, payment processing, and surge pricing logic. The backend complexity is what drives cost here.
MVP
$120K – $250K
6 – 9 months
Marketplace / booking
Web + Mobile
Airbnb
BookingTwo-sided marketplace with listings, search/filter, booking calendar, in-app messaging, reviews, and payment escrow. Verification and trust systems add complexity.
MVP
$100K – $220K
5 – 8 months
Food delivery
Mobile
Uber Eats
DoorDash
DeliverooSimilar to ride-hailing but with three parties (customer, restaurant, driver), plus menu/inventory management and order status tracking in real time.
MVP
$130K – $280K
6 – 10 months
Messaging / social
Mobile
WhatsApp
Signal
TelegramThe core functionality (1-to-1 and group messaging, media, contacts) is relatively contained. Encryption and reliable delivery across flaky connections add the real challenge.
MVP
$80K – $160K
4 – 7 months
Fitness / wellness
Mobile
Strava
FitbitActivity logging, GPS route tracking, data visualisation, social features, and wearable device integration. Content libraries (workouts, meal plans) add scope quickly.
MVP
$70K – $150K
4 – 6 months
E-commerce
Web + Mobile
Shopify
WooCommerceCustom e-commerce (not just a Shopify theme) with product management, cart, checkout, payment processing, shipping integration, and an admin dashboard for the business.
MVP
$60K – $140K
3 – 6 months
Business & SaaS Apps (B2B)
Business software has its own cost profile. The interfaces are often simpler, but the data models, permissions, integrations, and multi-tenancy underneath are where the complexity lives.
Team communication
Web app
Slack
TeamsOrganised channels, threaded conversations, file sharing, search across message history, and a plugin/integration ecosystem. Real-time infrastructure is the backbone expense.
MVP
$100K – $200K
5 – 8 months
Project management
Web app
Trello
Asana
ClickUpKanban boards, list and timeline views, task assignment, due dates, and team permissions. Simple on the surface, but real-time collaboration and flexible data models add depth.
MVP
$60K – $130K
3 – 6 months
CRM / sales platform
Web app
HubSpot
Salesforce
PipedriveContact and deal management, pipeline views, email integration, activity logging, reporting dashboards, and workflow automations. Multi-tenancy and role-based access are table stakes.
MVP
$90K – $200K
5 – 8 months
Scheduling / booking
Web app
Calendly
Cal.comCalendar integration, bookable time slots, automated reminders, timezone logic, and payment collection. Deceptively simple, but calendar sync edge cases are where time gets spent.
MVP
$40K – $90K
2 – 4 months
Invoicing / accounting
Web app
Xero
QuickBooksInvoice creation, bank feed integration, transaction reconciliation, tax calculations, and financial reporting. Compliance and accuracy requirements make this a precision-heavy build.
MVP
$100K – $220K
5 – 9 months
Learning / LMS
Web app
Teachable
ThinkificCourse creation tools, video delivery, learner progress tracking, assessments, certificates, and subscription billing. Content management and video infrastructure are the main cost centres.
MVP
$70K – $150K
4 – 7 months
"It's about creating the 'experience layer' on top, the interface that makes a product relevant for people to use while quickly demonstrating its value."Henrik Werdelin, co-founder of Prehype
What tier is your project?
Not every project needs to be a six-figure build. Here's how we think about the three broad tiers of custom software development.
Focused tool
$30K – $80K
2 – 4 months
- ✓Single core workflow
- ✓Up to 5–10 screens
- ✓Basic authentication
- ✓One or two integrations
- ✓Web OR mobile (not both)
Full product
$80K – $200K
4 – 8 months
- ✓Multiple user roles
- ✓15–30+ screens
- ✓Payments and subscriptions
- ✓Third-party integrations
- ✓Admin dashboard
- ✓Web and/or mobile
Platform / enterprise
$200K+
8+ months
- ✓Multi-tenant architecture
- ✓Complex data models
- ✓API ecosystem
- ✓Advanced permissions
- ✓Compliance requirements
- ✓Scale for thousands of users
Where the money actually goes
People are often surprised that "building the features" is less than half of a well-run project. Here's a typical cost breakdown.
30%
UX & Design
Research, wireframes, UI design, prototyping, and usability testing. Getting this right first saves money later.
35%
Development
Frontend, backend, API development, database design, and third-party integrations.
15%
QA & Testing
Manual and automated testing, device testing, performance testing, and bug fixing cycles.
10%
Project Management
Sprint planning, stakeholder communication, backlog grooming, and keeping everything on track.
5%
DevOps & Infrastructure
CI/CD pipelines, hosting setup, monitoring, and deployment automation.
5%
Launch & Handover
App store submissions, documentation, training, and post-launch support planning.
What makes an app cost more (or less)
These are the factors that move the needle most. Understanding them will help you make smarter trade-offs before you start building.
Platform choices
Building for web, iOS, and Android triples the surface area. Cross-platform frameworks like Flutter can reduce this by 30–40%, with some trade-offs. Starting with one platform and expanding later is usually the smartest move.
Integrations
Every third-party service you connect to (payment gateways, maps, email, SMS, analytics) adds development time and ongoing maintenance. Each integration can add $5K–$15K to the build.
User roles
A single user type is straightforward. Add an admin panel, a driver app, a vendor portal, and you're effectively building multiple products that need to work together.
Real-time features
Live chat, GPS tracking, collaborative editing, and real-time notifications require WebSocket infrastructure and careful state management. These features punch well above their weight in terms of backend complexity.
Security & compliance
Handling financial data, health records, or operating in regulated industries means encryption, audit logging, and compliance frameworks, all of which add to the build and ongoing costs.
Scale expectations
An app for 100 users and an app for 100,000 users are architecturally different. Building for premature scale wastes money, but retrofitting later can cost more. Finding the right balance is key.
