Hardware leases are one of the worst deals in merchant services. A $400 retail terminal leased at $50/month for 48 months costs $2,400 — six times retail. The lease is typically non-cancellable, separate from your processing contract, and often outlasts the processing relationship itself (so you keep paying for a useless terminal after switching processors).
If a processor offers 'free terminal placement' as part of a lease, the cost is buried in the lease and your processing rates. If they offer to buy the terminal outright at retail or near-retail, that's fine. Reputable modern processors (Helcim, Stax, Dharma) sell or rent terminals at fair prices and never push leases.
If you already have a hardware lease, check the cancellation language. Most leases have no exit before term end — you may be stuck paying out the remainder regardless of whether you process through that company.
