How Much Does Web App Development Cost?
Web app vs website
A website mostly shows information. A web app lets users log in, enter data and get work done: portals, dashboards, booking systems, CRMs and SaaS products. That’s why web application development cost is higher than a website.
Web app development cost by type
| Web app | Typical cost |
|---|---|
| Admin dashboard / internal tool | $10,000–$18,000 |
| Booking or quoting system | $12,000–$25,000 |
| Client portal with payments | $18,000–$30,000 |
| Multi-tenant SaaS | $30,000–$50,000+ |

- User roles and permissions
- Number of screens and workflows
- Integrations (CRM, accounting, payments, APIs)
- Reporting and dashboards
- Security and compliance needs
- AI features
These explain most of the web app development cost differences between quotes.
Ongoing costs
Hosting (AWS, Vercel) is usually $20–$300 a month for small and mid-sized apps. Maintenance and improvements typically run 15–20% of the build cost per year.
Questions to ask a web app developer
- Which stack will you use, and why?
- How do you handle security and backups?
- Will I see working software every two weeks?
- Do I own the code and cloud accounts?
- What does support cost after launch?

Build vs buy
If an off-the-shelf SaaS fits 80% of your process, buying is usually cheaper. Build when your process is a competitive advantage, when you’re paying for several tools that don’t talk to each other, or when you plan to sell the software yourself.
