What the published guides say
Most of the pages that rank for this question come from software development agencies. Their ranges:
| Kind of project | Range quoted |
|---|---|
| A simple internal tool | About $20,000 to $30,000 |
| A small business utility | About $25,000 to $75,000 |
| A broad custom application | About $50,000 to $500,000 |
| A large system | $100,000 to $400,000 and up |
| Enterprise software | $1 million and up |
These are the guides' own figures on the date at the bottom of this page. They describe what agencies with full project teams charge, and they are a fair picture of that market.
What drives the price
Every estimate, from any builder, comes down to the same handful of factors:
- Scope. The number of screens, records and workflows. This matters more than anything else.
- User roles. Each kind of user who sees different things (owner, office, sales, crew, customer) adds rules and testing.
- Integrations. Payments, email, texting, accounting, calendars and maps each add work and ongoing costs.
- Data migration. Moving years of records out of spreadsheets or another system takes cleanup.
- Design polish. A clean, practical interface costs less than a heavily branded one.
- Who builds it. A large team with project managers costs more per week than a small studio, and offshore teams price differently again.
- What happens after launch. Hosting, support and changes continue for as long as the software runs.
How an owner-run business can keep the cost down
- Solve one expensive problem first. An estimate builder, a follow-up system or a job board is a project. "Run the whole company" is a program.
- Write down your process before anyone quotes. Builders price uncertainty high.
- Keep the tools that work. If your accounting software is fine, connect to it rather than rebuilding it.
- Plan a second phase. Features you are not sure about can wait until the first version proves itself.
Signs you are ready for custom software
- You pay for a subscription and work around it every day, with spreadsheets and text threads filling the gaps.
- A rule that costs you money keeps getting skipped, such as scheduling before a permit or sending prices to the wrong person.
- The same information is typed twice, from a form into a list, from a list into an estimate.
- You can describe the process clearly. Software makes a clear process faster; it does not fix an unclear one.
If none of these sound familiar, a good subscription is probably enough for now.
Why a focused build can cost far less
Sky2Screen is a small studio, led by its founder, that builds for owner-run businesses. A focused Sky2Screen build is usually well under the ranges above. It is built around one owner's process instead of every possible customer, it starts from parts that already work in other client systems, the work is AI-assisted, and there is no account team between you and the person scoping the work.
Examples of what custom software does for a small business
Systems Sky2Screen has built:
| Built for | What it does |
|---|---|
| A roofing contractor | Runs jobs, stages, pipeline, money, crews and materials; nothing is scheduled before a signed contract and an approved permit; crews never see dollar figures |
| A tile installer | Turns a quote form into a scored lead and then a branded PDF estimate; installers never see money |
| Old, unsold quotes | A reactivation CRM that follows up by email and text and stops when a customer replies |
| Men's Legal Center | Clara, an AI assistant that answers by chat and voice from the firm's own videos; 56% to 98.8% on an 80-question test |
| Premium Decor SD | A furniture store on its own data service, with an admin for orders, inventory and delivery |
Demos of these systems run on made-up businesses, never on a client's data.
Owning compared with renting
Custom software competes with subscriptions as much as with other builders. A field service plan such as Jobber Grow, listed from $149 a month billed annually, comes to $8,940 over five years before extra users; GoHighLevel's Unlimited plan, listed at $297 a month, comes to $17,820. A system you own has a build cost, then hosting, which is quoted in writing with the build. If you plan to use the software for years and a subscription does not fit your process, owning is worth pricing. If a subscription already does the job, keep it.
How to get a quote you can compare
Ask every builder for the same three things in writing: exactly what is included, what is not, and what happens after launch. At Sky2Screen, a quote starts with a short form; Elian Gonzalez, the founder, calls you, then sends the quote in writing. Sky2Screen is based in San Diego and serves owner-run businesses across the United States, and a demo is an online video call.
