PartsMinder develops a cloud based purchase order management too that lets you manage your corporate purchasing.
From a deceptively simple dashboard see what's going on with all purchasing activity at your organization. Make orders, monitor others' ordering, set limits, require permissions, restrict access, track pricing, confirm deliveries, track short orders, group by projects, departments, vendors, material, customize options, export data to accounting. Execute, track, and control all your money requests and expenditures before it's too late.
