Stick it on the can once, and every delivery or pickup confirmation becomes a point-and-scan. 1. ## Open a unit's sticker In the expanded units panel or the "Summary of {size}" page, click the QR icon next to a serial. The dialog, titled "QR sticker" with the serial, explains: "Print or download. Each QR is unique to this unit and lets the driver app auto-select it on scan." 2. ## Print or download it The preview shows the serial in large type, the QR code, and the Dumpster Controls footer. Use "Print" for a direct print or "Download PDF" for a file. 3. ## Batch-print a whole size Click "Print stickers PDF" in the units panel header (also available on the size summary page) to download one PDF with a sticker per unit, named like 20-yard-qr-stickers.pdf. 4. ## Renumber when the list gets messy "Renumber All" opens a dialog ("Renumber all {size} units") that renames every active unit in order of registration to a clean sequence, previewing the first and last serials. A warning notes that drivers will see the new names on their next refresh, and that units in use are renamed too with their dispatch and order links intact. 5. ## Scan during operations In the delivery and pickup confirmation forms, the "Scan QR code" button opens the "Scan dumpster QR code" camera dialog ("Point the camera at the QR code on the dumpster."). A successful scan selects the unit and toasts "Unit selected" with the serial. ## What happens next - Drivers get the same power in their app: scanning the sticker auto-selects the unit on their delivery and pickup steps. ## Troubleshooting ### The camera never starts. The dialog reports the exact cause: "Camera permission denied. Please allow camera access in your browser settings." or "No camera was found on this device." ### The scan says "Unit not found". "This QR code does not match any unit in your inventory." The sticker belongs to another company or a deleted unit; reprint from the current list. ## Related guides - [How to manage individual units and serial numbers in Dumpster Controls](https://dumpstercontrols.io/help/inventory/manage-units-and-serial-numbers) - [How to mark an order as delivered in Dumpster Controls](https://dumpstercontrols.io/help/inventory/mark-an-order-as-delivered) © 2026 Dumpster Controls.

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. ### How do I switch from another dumpster software? Create a free account at dumpstercontrols.io/login, with no sales call and no credit card. Then import your customers from a CSV file using the template provided in the app; past orders can also be imported from a CSV. Container sizes and pricing are set up in Settings. The landfill database, with 1,750 active US and Canadian landfills as counted on 2026-10-01, is already loaded, so disposal sites do not need to be typed in.
