Answer
Two quotes can describe the same visible interface and still contain completely different services. One price may cover only the programming of a prototype. Another takes into account data migration, roles and permissions, interfaces, testing, documentation, publication, monitoring, backups, training and a safeguarded roll-out. Unclear requirements also lead to large risk surcharges or to very low bait offers followed by change requests later.
For a reliable comparison, you should ask about more than just features. What matters are the assumptions, excluded services, acceptance, ownership and access, operational responsibility, follow-up costs and how changes are handled. For unclear projects, schukai does not give a figure that only appears precise. A more sensible approach is a limited first investigation or implementation step, after which the data situation and risks are better understood. This does not eliminate every uncertainty, but it makes it visible and allows an economically sound decision.
