Matching terminal tier to transaction volume is the real decision retailers should be making. A single register convenience store does not need the same hardware as a busy multi lane grocery counter, and buying more power than the business uses just adds cost without adding speed where it counts. For a closer look at how terminal tiers break down by processor and use case, see retail pos system.

Connection type decides whether the drawer actually opens when it should. Most retail cash drawers connect through the receipt printer using an RJ11 or RJ12 cable, which means the drawer needs to be compatible with whatever printer the store uses, not just the terminal. A mismatched connector is one of the most common reasons a new drawer sits unused in its box for a week before someone notices.

Label width is the first practical decision, since a 4 inch thermal label printer covers most standard retail and shipping label sizes, while narrower printers suit smaller product tags. Linerless label stock is worth understanding before buying, since it removes the backing paper waste that standard label rolls produce and can extend how many labels a single roll holds before it needs replacing.

Cost comparison is not as simple as it looks on paper either. A basic cash register costs less upfront, but a business that outgrows it ends up paying twice, once for the register and again for the POS system it should have started with. A POS terminal built for the transaction volume a business actually expects avoids that repeat cost.

A more complete way to budget is to price the full setup, terminal, printer, drawer, and scanner, against the transaction volume the business expects, rather than comparing a single terminal price across different vendors. For a full cost breakdown by terminal tier, see cash drawer.

Ongoing costs matter as much as the upfront number. Receipt paper, POS software subscriptions chosen separately from the hardware, and eventual replacement of wear items like cash drawer components all add up over a year of daily use. A business budgeting only for the initial purchase price is not seeing the full picture of what running a POS setup actually costs.
