Frequently asked questions
Is Dumpster Controls really free?
Yes. The entire app is free for any company at any fleet size: dispatch, online booking, the driver app, invoicing, the Tresha AI assistant and every other feature, with no monthly fee, no trial period and no credit card to sign up. The only cost on the free plan is optional card processing when a customer pays by card through the platform: 2.99% plus $3.99 per transaction on the free plan. The entire app is free; an optional $169 per month plan lowers that to 2.99% plus $0.30 and adds a Sponsored spotlight in the public company directory. Prices as published on dumpstercontrols.io/pricing on 2026-09-23.
Do you charge per driver, per truck or per order?
No. There is no per-driver, per-truck, per-user or per-order fee, and no order limit. A company with one truck and a company with twenty pay the same for the software: nothing.
Is there a contract?
No. There is no contract, no minimum term and no setup fee. You create the account yourself, and on the free plan there is nothing to cancel because nothing is billed. The optional $169 lower card rate plan is billed month to month.
Which countries and languages are supported?
Dumpster Controls serves hauling companies in the United States and Canada. The app interface and the Tresha AI assistant are available in English, Spanish and Portuguese. The public pages, such as the blog, the help center and the landfill finder, are in English.
