Describe your needs in numbers
Office and commercial equipment has to fit your workflow. For a printer, the expected print volume and consumables matter; for shelving, dimensions and a documented load rating; for electronic equipment, connections and software. «Professional» is not a measurable specification.
Check the space, power and connection requirements. Equipment that worked in one company may need a different setup in its new place. Find out whether licences and accounts can be transferred and whether separate activation is needed.
Find out about testing and upkeep
For a used printer, powering on doesn't confirm print quality or that every paper feed works. The page counter helps judge wear if it's available, but it doesn't replace a working test. Look for a specific result, not just a clean case.
Work out the cost of spare parts, consumables and servicing. An older, cheap model can mean hard-to-find parts or software. For warehouse equipment, missing fixings and an unclear load rating must be resolved before use.
Plan the purchase and installation
On the lot page, check the seller, what's included and collection. If you need the invoice in a company name, enter the details in your account before paying: the invoice recipient can't be changed after payment. Heavy equipment needs exact dimensions, weight and loading arrangements. Compare how ready it is for use together with installation and service needs.
