Custom Software Development: The Rocketech Approach, From Brief to Release

We build custom software in a fixed order. We start from your process and the software you already have. We price the work before we build. We ship the narrowest first release that proves the idea, then keep working in short cycles where you see working software every time. You own the code, the designs and the accounts throughout.

This post walks through each step with our published prices and real timelines from our projects, then lists the common beliefs about custom software that this process answers, and the cases where we’re the wrong choice.

Step 1. Start from the process, not the code

Custom software development at Rocketech starts with your process. We map the steps, the exceptions, the data involved and the points where a person must review the result. We look at existing software first, then compare three routes for each part: set up a tool you can buy, connect the tools you already have, or write custom code. Our guide to ready-made vs custom software shows how to put numbers on that choice.

When the job is to automate one workflow, the first build is a pilot. It costs $5,000-15,000, takes 2-4 weeks and goes in four steps: pick one workflow, map the process, build the automation, then test it against agreed checks so your process owner can decide whether to roll it out.

Step 2. Price it before we build

Two tools come before any code.

Our project estimate turns your brief into user stories, and every hour in the budget traces back to a story you confirmed. That gives you a range before you talk to anyone.

The discovery sprint turns the range into one price. It’s a fixed $3,000 for one week: a written scope, the main user flow and up to 6 main screens for one platform in a clickable Figma prototype, a technical plan, a one-day test of the riskiest technical question where there is one, a backlog with hours and a fixed price for the build. It counts toward the MVP if you build it with us, and the files are yours either way.

Step 3. Ship a narrow first release

The first release does one main job. Sign-up, payments and admin panels come from ready-made modules, so the team spends its time on the part that is new. A typical MVP costs $5,000-15,000 and takes 2-4 weeks. For iPhone and Android apps, store review time comes on top; Apple says it reviews at least 50% of submissions in less than 24 hours and 90% in less than 48 hours (Apple App Review).

Larger first releases are priced by the hour. IPOPBOOKS, a bookkeeping platform for US small businesses, went live 10 weeks after kickoff, and our bigger SaaS builds took 2 to 6 months.

For comparison, across 95 agencies the median published MVP starting price is $13,234 and the median promised timeline is 6 to 12 weeks (Rocketech MVP Price Index 2026).

Step 4. A small senior team, short cycles and AI tools

A small team of middle and senior engineers builds the release, using the short cycles of Extreme Programming, Scrum, Customer Development and Lean Startup. We use AI tools in development, and in the products we build we use AI only where it helps the task. Our in-house AI R&D department fine-tunes models, works on AI security and builds AI-native development workflows.

The industry data explains why the team’s experience still matters. In the Stack Overflow Developer Survey 2026, 73% of respondents said they use coding assistants and agents daily. In the same survey, 69.3% named “plausible but wrong code” among the AI mistakes that cost them the most time (Stack Overflow 2026 technology results). Google’s 2025 DORA report put it in one line: “AI doesn’t fix a team; it amplifies what’s already there” (Google Cloud, DORA 2025).

Step 5. Working software at every review

We build in short sprints and show you working software at the end of each one. You keep the product priorities and the business decisions. On Traza, a booking app for tattoo artists, the team worked in weekly cycles on the client’s own Jira with regular demos, and the client could change priorities every week.

Step 6. You own what we build

In a classic project, you own the code, the designs and the accounts. IPOPBOOKS, Koncierge and HealthyNikah run on their owners’ own AWS accounts. You can ask for an NDA before you share anything. The one exception is a SaaS that we pay to build ourselves: there we keep the code and the IP, and we say so up front.

Step 7. After launch: hourly work or a team

After the first release, the work continues at $39-55 an hour, or with a dedicated team at $6,000-9,000 per developer a month. A team starts in 3-5 days when everyone comes from our staff or pool, or within 2 weeks if we hire someone new. The long arc is the one on our workflow page: concept, prototype, MVP, full product, then scaling.

Five beliefs about custom software, and what we do instead

BeliefWhat we do insteadWhere it shows
Custom software is always expensive and slowA narrow first release, typically $5,000-15,000 in 2-4 weeksEasySpk and GhostMinutes each reached the App Store in 2 weeks

Common beliefs about custom software development, and how our process answers them

When we’re the wrong choice

We say no, or point elsewhere, in these cases:

  • Your budget for the build is under $5,000. Below that we only sell the fixed-price UX audit, discovery sprint and code audit.
  • You want many features in the first release. Our 2-4 week timeline comes from a narrow first release.
  • You want a fixed price while your requirements change every week. Each change reopens scope and price.
  • A ready-made tool does the job at a price per seat that fits your margins. Buy it instead of building.

How we would estimate your project

  1. Our project estimate turns your brief into user stories. You confirm what’s in scope, and every hour in the budget traces back to a story you kept.
  2. We check the hours the model suggests against what our team actually books on finished projects, then multiply by our published rate of $39-55 an hour. You get an hours range, a budget range and a timeline. It’s a planning range, not a fixed quote.
  3. The unit economics show how many customers pay for the build and in which month it’s paid back. You can change any starting number and the math updates.
  4. For market size, the estimate suggests customer groups and gives each a TAM, SAM and SOM with a note on what the number covers. Treat them as hypotheses to test, not verified demand.

You can see what your project costs to build in about four minutes, before you talk to us or anyone else.

What we would do

  1. Write down the process you want the software to run, step by step.
  2. Mark which steps a tool you can buy already covers.
  3. Get an estimate for the rest, and cut the first release to one main job.
  4. Buy a one-week discovery sprint if you need one fixed price.
  5. Build the first release, and judge it by what real users do with it.
  6. Decide after launch whether hourly work or a dedicated team fits the next stage.

FAQ

How does Rocketech approach custom software development?

We start from your process and the software you already have, price the work before we build it, ship a narrow first release, and then work in short sprints with working software at every review. You keep the product decisions and own the code, the designs and the accounts.

How long does a custom software project take?

A typical MVP takes 2-4 weeks, plus store review for mobile apps. A workflow automation pilot takes 2-4 weeks. Larger first releases take longer: IPOPBOOKS went live 10 weeks after kickoff, and our bigger SaaS builds took 2 to 6 months.

How much does custom software development cost?

Our rate is $39-55 an hour, and the smallest build we take is $5,000. A typical MVP costs $5,000-15,000. A one-week discovery sprint costs a fixed $3,000 and counts toward the build, and a dedicated developer costs $6,000-9,000 a month.

Who owns the code Rocketech writes?

In a classic project, you do: the code, the designs and the accounts are in your company’s name. The only exception is a SaaS that we pay to build ourselves, where we keep the code and the IP.
