Online boiler and heating parts supplier

Plumbers, HVAC technicians and small heating contractors who need parts fast, plus some landlords and property managers.

• Knowing heating system parts and model numbers
• Sales and building trade relationships
• Order tracking and organization

• Check whether manufacturers need an approved dealer agreement before you can sell their brands
• Check your state's rules for a resale certificate and sales tax collection, especially across state lines
• Product liability and general liability insurance, since faulty parts can cause damage
• Returns, warranty claims and wrong-part orders can eat into thin margins
• Big online sellers and supply chains compete on price, so service and speed matter
• Check whether your city or county requires a business license, and HOA or lease rules if you run it from home

Estimates typically put startup costs around $2,000 to $10,000, depending on your website, how you set up supplier relationships and whether you hold any stock. Treat these figures as estimates, not guarantees.

Monthly revenue is typically estimated at around $3,000 to $15,000, depending on your supplier terms, how many contractors you win and how fast you ship. Returns and wrong-part orders can eat into thin margins.

Check whether manufacturers require an approved dealer agreement, and your state's resale certificate and sales tax rules, especially across state lines. Also check product and general liability insurance, and any city or county business license, HOA or lease rules.
