How long does the development of a software take? Realistic time frames for MVPs, web apps and enterprise solutions.
“Digitalization is not an IT project—it is a business strategy.”
– Björn Groenewold, Managing Director, Groenewold IT Solutions
How long does software development take? – one of the most common questions before project start. The answer depends on the project type and the framework conditions.
Time frame by project type
Short: | Project type | Typical duration | |---------------- | MVP / small application | 2–4 months | | Web-App / Portal (medium) | 4–8 months | | Enterprise solution / integration | 6–18+ months |
| Project type | Typical duration | |---------------- | MVP / small application | 2–4 months | | Web-App / Portal (medium) | 4–8 months | | Enterprise solution / integration | 6–18+ months |
A MVP can often stand in 2-4 months; a medium web app or portal with connections needs more than 4–8 months. Large or strongly integrated systems can take 6–18 months and more.
= influencing factors
Complexity of requirements, number of interfaces, quality of specification, team size and availability, regulatory or technical requirements. All this extends or shortens the duration.
Realistic plan
Short: Buffer schedule for uncertainties and changes.
Buffer schedule for uncertainties and changes. Agile procedure provides early partial results – so you can also benefit more quickly in longer projects.
Quality: There are no flat-rate answers – but realistic bandwidths. We will appreciate your project. More under [Individual software development](/services/software development) and [MVP development](/services/mvp development).## Billing after effort: What is better?
Festpreis offers planning security and a clear budget. Cons: less flexibility in change requests, the risk of Scope Creep and a higher initial effort for a detailed specification. Fixed price is well suited for MVPs and clearly defined projects with a fixed scale.
Calculation after effort (Time & Material) allows maximum flexibility and adjustment during development. Disadvantages: the budget is harder to calculate, and it requires trust and regular voting. T&M is suitable for complex, long-term projects with changing requirements.
**For a clearly defined MVP or a well-describable project, fixed price is often the better choice. For exploratory or changing projects, billing is more sensible after effort. Groenewold IT offers both models – we advise you which fits your project.
5 Tips to Shorten the Development Time
Short: (1) Define clear requirements before project start – The more precise the goals and scope, the less demand and rework during development.
(1) Define clear requirements before project start – The more precise the goals and scope, the less demand and rework during development. (2) MVP approach – Instead of building everything at once, first deliver the core functions and then expand iteratively.
(3) Use the experienced team** – Experienced developers avoid typical fall knits and deliver faster quality-conscious code. (4) Use existing frameworks and libraries – Do not reinvent any wheel; proven components save time. (5) Give regular feedback** – Thus, malformations are detected early and can be corrected before they become expensive.
Frequent questions about the duration of software development (FAQ)
Short: **Can you speed software development by using more developers?
**Can you speed software development by using more developers? ** Only limited. Too many cooks spoil the Brei – coordination and communication grow. A larger team can help with well-dividable modules.
How exactly are time estimates for software projects? With clear scope typical ±20–30 %. In the case of unsharp requirements, estimates are uncertain. Agile sprints with running increments reduce the risk.
What happens if the project lasts longer than planned? At fixed price, the provider carries the risk (up to the agreed limit). For T&M, the additional costs are calculated. Important: communicate early and discuss options.
Is offshore development faster? Not automatically. Time shift and voting costs can destroy the alleged time savings. Quality and wartability must be correct.
How long does maintenance last after the go-live? This is subject to agreement. Typically a support period of several weeks to months; then optionally running maintenance contract for updates and troubleshooting.
