If you want simple estimating software for a plumbing, electrical, HVAC, or similar trades business, I’d narrow it down to three:
Joist — probably the simplest. It’s built around estimates → approval → invoice → payment, with line items, markups, deposits, photos, and mobile use. It’s particularly suited to an owner-operator or small crew that doesn't need a full dispatch system.
Jobber — a good step up if you also want scheduling, customer management, quoting, invoicing, payments, and job tracking. It's commonly used by plumbing, electrical, HVAC and other field-service businesses.
