How long does a CRM implementation take?

What really determines the duration

Data quality. A well-maintained database can be migrated in days. Fifteen years of Excel lists grown with duplicates and inconsistent spellings can take weeks – and this work cannot be delegated to anyone else because only you know which dataset is correct.

Decision-making processes. If every inquiry waits a week for a response, the project duration doubles, regardless of the technology used.

Scope of interfaces. Each connection to a third-party system brings its own alignment, test data and error scenarios.

A sensible scope

Not everything at once. Proven approach:

1. Contacts, companies and tasks – the core used daily
2. Sales process with status and reporting
3. Interfaces to accounting and email
4. Automations once the workflow is stable in daily operations

After step one, the team is already working in the system. This is more valuable than having a complete system after nine months.

What saves time

A fixed contact person with decision-making authority, test users identified early from daily operations, and willingness to leave old data behind rather than taking everything along.
