How long does custom software take? Realistic timeline
A custom software project isn't a weekend job, but it's not a six-month project either. What happens in which order, where things typically get stuck, and how to shorten the timeline.
In practice, custom software takes from 8 weeks to the first version. The biggest time factor is almost never the implementation itself, but how quickly content, access, and decisions come from your side.
01 — Timeframe
How long it takes
- Typical duration
- from 8 weeks to the first version
- Price
- Individual based on effort
The timeline starts after approval of the quote. Lead time for initial meeting and quote: typically one to two weeks. We provide a fixed price after this initial meeting.
02 — Process
The steps in detail
Understand the process
We watch how work is done today. This regularly uncovers requirements no one would have mentioned.
Minimum usable version
What's the smallest piece that already helps in daily work? That's where we start.
Expand
In two- to four-week increments, each with something you can use.
Handover
Documentation, training, source code. You shouldn't be tied to us.
03 — Bottlenecks
What typically causes delays
- Content and deliveries. By far the most common cause of delay. Text, images, price lists, access credentials — what's missing blocks progress.
- Decisions. When it's unclear who approves, the project waits. A named contact person with decision-making authority noticeably shortens the timeline.
- Access to third-party systems. Getting access to inventory management, phone systems, or CRM regularly takes longer than the integration itself.
- Endless review rounds. Two correction rounds are normal, five are a sign that the goal wasn't clear at the start.
04 — Scope
What's included
- Requirements gathering with the people who will be working with it
- Implementation in small, usable steps instead of as a large-scale project
- Migration of existing data from spreadsheets and legacy systems
- Roles and permissions, logging, and backup from the start
- Integration with your existing systems instead of creating another silo
- Documentation and source code that belongs to you
05 — Questions
Frequently asked questions
How do we avoid the project going off the rails?
Small steps with usable results, fixed budgets per step, and the option to exit after each step. Large fixed-price projects over twelve months are the most reliable path to disappointment — for both sides.
Can we start with a spreadsheet?
Often yes, and that's a good test. If the spreadsheet maps the process and only fails due to multi-user capability, permissions, or data volume, the requirement is clear and the project is calculable.
Who owns the source code?
You do, completely, upon payment. That's in the contract. You can take it to any other developer — that's the point.
Does this run on our own servers or in the cloud?
Both are possible. For most businesses, a cloud solution is lower-maintenance; where data must not leave the premises, we set it up on your own infrastructure.
How many users can a system like this handle?
That depends on the architecture, which we plan according to your expected growth — from a few users in your own business to several hundred across multiple locations.
When does custom software pay off compared to standard software?
When your process is a genuine competitive advantage, when standard software only fits seventy percent and the rest ends up as manual work, or when license costs per user exceed the development cost over a few years. If it's only about convenience, standard software is cheaper.
What if we discover new requirements during development?
That's normal and planned for, because we work in small steps. A new requirement is incorporated into the next step, instead of stalling the entire project.
