Frequently Asked Questions

When should I sub-rent from a competitor?

Sub-renting makes sense when you have a customer order you can't fill from your own inventory, and the margin is at least 20-30%. It's also smart when losing the order would mean losing a high-value repeat customer. Never sub-rent just to say yes to every order, especially if the margin is thin and the logistics are complex.

What is a good margin on a sub-rental?

Aim for at least 25-35% margin on sub-rentals. Anything below 15% is usually not worth the effort when you factor in coordination time, liability risk, and the chance something goes wrong with equipment you don't control. If the margin is thin, negotiate a lower sub-rental price or charge the customer more.

What are the risks of sub-renting?

The biggest risk is quality control: you're putting your reputation behind equipment you didn't maintain. Other risks include damage liability (who pays if the customer damages the sub-rented item?), scheduling conflicts, and the competitor learning about your customer. Always have a sub-rental agreement in writing.
