A company could offer separate paths for an occupied home and commercial premises. The first would ask about rooms and furniture; the second about surfaces and access periods. Photos and deadlines would follow the correct record. Staff could then arrange a visit or prepare the missing questions before developing an estimate for the actual work.
An illustrative example to adapt to your business. It does not represent a completed project in this municipality.
Are two separate websites necessary?
Not necessarily. Two service pages with suitable forms can preserve one business identity while collecting the different information needed for residential projects and work in commercial premises.
How should incomplete enquiries be tracked?
Give them a clear status and identify the missing detail. A reminder can point to that specific question and let the customer resume without completing every field again.
