Is Dumpster Controls really free?

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.

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.
