How to sell to contractors in Whitby

This category covers general contractors, renovation firms, builders, excavators and concrete and framing companies. Projects are larger and longer, and the person you need is usually the owner or the estimator.

Who sells to contractors

  • Construction software (estimating, scheduling, takeoffs, project management)
  • Equipment rental and heavy-equipment dealers
  • Building-materials suppliers
  • Bonding, builder's risk and liability insurance
  • Accounting and job-costing firms
  • Subcontractor and trade recruiting

What keeps owners up at night

  • Cash flow between progress payments
  • Bidding accurately and winning the right jobs
  • Coordinating subs and keeping schedules
  • Labour shortages
When to reach themEarly morning, before site visits, or late afternoon. Winter is planning and bidding season in colder markets, which is a good time to sell software and services.
The angle that worksTalk about margin and schedule risk. "How much did your last job overrun?" opens more doors than "we save you time."
Reaching out in CanadaCold email to Canadian businesses falls under CASL, and phone outreach falls under the CRTC's telemarketing rules. A business address that's published publicly can support implied consent for messages relevant to that business, but every email still needs your identity and a working unsubscribe. Read our plain-English CASL guide and cold-calling rules before your first campaign.
