Match your company's task to a tool.

Illustrative workflows, not customer case studies. Company types describe the work; roles identify who uses the tool.

  • Mechanical/HVAC and plumbing contractors

    Record hours against each project

    Role: Crew lead → office admin

    A technician selects the client and project for a service visit; the office reviews the recorded hours for payroll preparation.

    Explore TradeLog Site

  • Electrical and specialty installation contractors

    Leave a record of work completed

    Role: Technician → project manager

    An installer adds project notes and photos so the manager can review site conditions and remaining work.

    Explore TradeLog Site

  • General contractors, remodelers and maintenance/service teams

    Keep assignments and job records together

    Role: Owner, crew lead and office admin

    The team checks scheduled work and keeps updates with the right project instead of mixing records from separate jobs.

    Explore TradeLog Site

  • Piping, mechanical and refrigeration teams

    Review a piping route before fabrication

    Role: Fitter → estimator

    A fitter draws a dimensioned run; with Pro, an estimator reviews the takeoff and cut lengths, then enters the shop’s own rates and prices.

    Explore LionSync ISO

  • Finish carpentry and cabinet/millwork shops

    Add or split fractional dimensions

    Role: Carpenter or cabinetmaker

    Add 2 3/4 and 1 1/2 to get 4 1/4 as a number, without converting both entries to decimals.

    Explore Contractors Calculator

  • Fabrication/installation shops, remodelers and DIY

    Reuse a result in the next calculation

    Role: Fabricator, installer or DIYer

    Divide 15 3/4 by 3 to get 5 1/4, then reuse or copy the result.
