Job wrapped early: do I pay the full month for the porta potty?

Yes, most construction rentals bill the full 28-day cycle when you return early, unless you negotiated a short-term or prorated rate before delivery.

The monthly standard portable toilet rate usually covers the unit, one delivery, one pickup, and a set service frequency for that billing window. Operators price it that way because the truck run and the slot on the route cost them whether the unit sits 12 days or 28. Early pickup does not erase that fixed cost on their side.

I have seen two ways out of a full-month invoice. First, ask for a weekly or short-term rate at quote time if the job might wrap early. Second, call before you request pickup and ask whether they will credit unused weeks toward another job or convert the remainder. Some will prorate if you give them notice; many will not after the fact once the invoice is cut.

Document what the quote said about the billing cycle and early return. If the contract is silent, you are usually stuck with the full month. Next time, put early-return terms in writing before the service truck drops the unit.

Brad covered the billing, but you can ask the rental company to mark your account as a good customer and apply the unused weeks to your next job. I see that happen with contractors who rent often. The key is to call them before you schedule the pickup. A driver like me shows up, pumps the unit, and loads it. That service visit and the truck run are already costs to the company, which is why the full-month rate sticks. If the contract didn't specify proration, you are paying for the unit slot on the route, not the calendar days it sat empty. For a crew of seven, you only needed the one standard portable toilet, so at least you didn't over-order.
