Custom software does not have to take a year. Here is a realistic timeline, what speeds a project up, and what slows it down.

Many business owners have heard horror stories of software projects that ran for a year and never went live. It does not have to work that way. With a clear scope and proven foundations, a first working version can be in your team’s hands in weeks.

A typical timeline

What speeds a project up

  • One decision-maker who is available weekly.
  • Starting with one process rather than everything.
  • Existing spreadsheets or forms to work from.
  • Willingness to go live with a first version and improve it.

What slows a project down

  • Trying to design every module before anything is built.
  • Complex integrations with older systems.
  • Decisions waiting on several people.
  • Scope that changes before the first version is live.

After go-live

Go-live is the start, not the end. On a subscription model, improvements continue every month, and new modules are added to the same system as the business grows. See what custom software costs or explore our custom business software.

Questions

Can a complex system be built in six weeks?

The first working MVP for a clearly defined process can be. Larger systems are delivered in stages, with the most valuable part live first.

How involved do we need to be?

Expect about an hour a week from a key person to review progress and make decisions.
