Compare the scope, not just the total.
Two proposals can describe the same property while covering very different work. List parking areas, internal roads, loading areas, sidewalks, steps and entrances separately. Identify any exclusions, shared responsibilities and areas where parked vehicles can prevent access.
Ask whether salting, sidewalk treatment, repeat visits and snow relocation are included or billed separately. Request clarification in writing when an item is unclear. A lower headline price does not establish that the proposal covers the same service.
