Cost questions

The cost questions we hear most

How much does custom software cost?

Most custom software we build costs $25,000 to $80,000. A focused internal tool can start from $15,000; enterprise systems and modernization start from $100,000 and are delivered in stages.

How much does a website cost?

Most business websites cost $3,000 to $7,000, and a landing page starts from $2,000. A larger content site costs $5,000 to $10,000. Most web apps cost $5,000 to $25,000; advanced web apps with many roles and integrations cost more.

How much does a mobile app cost?

Most business apps cost $20,000 to $35,000. A first version to test an idea can start from $10,000, and marketplace apps cost $30,000 to $50,000.

Why do quotes for the same project vary so much?

Usually because they cover different work. Check that every quote includes design, testing, data migration, launch, and support before you compare totals.

Do you charge fixed prices or by the hour?

Defined projects get a fixed price in writing. Open-ended work, such as ongoing improvements or a dedicated team, is billed monthly at rates agreed before it starts.

How do invoices and payments work?

The payment schedule is set out in your written quote before any work starts, so you know what is due and when. For a question about an invoice or a payment, email billing@dechytech.com.

What does software cost to run after launch?

Plan for hosting, updates, and improvements. Our care plans start from $100 a month for websites and $350 a month for apps in daily use.
