Your software is the problem.
If you're running on spreadsheets and free tools
- Your operations manager spends 15 hours per week copying data between systems.
- You rebuild quotes from scratch every time.
- You chase signatures on PDF proposals.
- Customers call asking "where's my installer?" because they have no visibility.
If you're running a CRM, field service software, and a separate quoting tool
- You pay someone to keep these systems synchronised.
- Your CRM doesn't talk to your scheduling software.
- Your quoting tool doesn't understand MCS compliance or DNO applications.
- Your field app shows appointments but not the technical specs installers need.
