Cash drawer
Secures the float and the takings, and creates the moment of accountability every time it opens.
A drawer is a lock, a denomination insert and a trigger. The trigger is the part worth understanding before commissioning: the drawer opens on a low-voltage pulse, and on most installations that pulse comes from a port on the receipt printer rather than from the terminal directly. That coupling surprises operators at the worst possible moment — a dead printer is a dead drawer, and the till stops trading for a reason nobody thinks to look for. Underneath there is a manual release, which exists for exactly that failure and is also the hole in the accountability model: any drawer that can be opened without generating a logged event can be opened without leaving a record.
- The decision is not the drawer, it is the accountability model the drawer serves. One drawer, one named operator, one shift, counted in and counted out with a second person present. A drawer three people share through a day is a drawer nobody is responsible for, and it converts every variance into an argument instead of an investigation.
- A card-dominant venue still needs the discipline, and the trap is to under-specify because cash volume is low. Low volume means fewer counts, less practice and weaker habits — the discipline gets worse as cash gets rarer, not better, and the drawer that is opened three times a day is the one nobody reconciles.
- Choose a removable insert if counting has to happen away from the floor, which in most venues it does. Counting on the bar in front of a queue is slow, error-prone and an advertisement.
- Check the opening arc against where people actually stand. A drawer that pushes the cashier back into the barista's hot lane every time it opens is a burn and a collision designed into the counter, and the workflow article's whole argument about crossed paths applies here as much as anywhere.
- Confirm what triggers the drawer and what happens when that trigger fails, in the commissioning meeting rather than during the first rush. If it opens from the printer's port, write the printer failure into the contingency plan explicitly.
- Document who may use the manual release and record every use. An undocumented release is not a security feature, it is an unlogged door.
- Cash is a hand-contact item on a bar that also handles open cups and milk. Site the drawer so the path from handling cash back to handling product passes a sink rather than a jug — this is a layout decision, and it is much cheaper than trying to train around a bad one.
At the payment end of the counter, tied to the terminal that logs its openings, and deliberately away from the pass so that paying and collecting stay two separate places for the guest to stand. It is also the one point on the bar where a hand goes from money to product, so the sink's position relative to it is part of the same layout decision.
- Sharing one drawer across a whole day because rostering a drawer per operator is administratively harder.
- Assuming a card-heavy bar has outgrown cash discipline, when it has only stopped practising it.
- Leaving the manual release undocumented and unlogged.
- Counting on the bar, in front of the room, because the office is a walk away.
- Mounting the drawer so it opens into the traffic lane behind the counter.
- Handling cash and then product without the sink being on the path between them.
- The drawer takes its opening pulse from a low-voltage port on the printer or terminal, so it has no supply of its own in most installations — which is exactly why its availability is inherited from that device. Where the installation differs, the installer confirms it.
- The real footprint is the fully extended drawer, not the closed unit. Measure the extension against where the cashier stands and where a guest leans on the counter.
- Under-counter mounting needs hand access to the full depth of the insert without crouching, and the drawer must clear knees, bin lids and any door beneath it.
- Condensation and splash are the enemy: a drawer sited under the steam path or beside a rinse point takes damp notes and tarnished coin, and damp notes slow every count for the rest of the week.
- Printer-driven under-counter drawer
- Standard steel drawer on runners, opened by a pulse from the receipt printer's drawer port.
- Simple and near-universal, and it inherits the printer's availability. If the printer is the thing that fails, the drawer fails with it.
- Terminal-driven drawer
- Opened by a software event from the terminal on its own cable, independent of the printer.
- Survives a printer failure and logs cleanly against the terminal's own audit trail. Costs another cable run and another driver to keep working through updates.
- Removable lockable insert
- The denomination tray lifts out as a locked cassette and travels to the office or safe intact.
- Counting moves off the bar and out of sight of the room, which changes behaviour rather than just storage. It is the variant that makes a two-person count practical at close instead of theoretical.
- Compact / flip-lid drawer
- A shallow unit that opens upward rather than sliding out, for short counter depth.
- Fits where nothing else does and holds fewer denominations. Generally less secure, and the lid opens into the operator's reach envelope rather than away from it.
- The drawer stops opening although the terminal is working normally.
- The printer that supplies the opening pulse has failed or lost its cable.
- The till cannot trade in cash, and the only workaround — the manual release — removes the audit trail for as long as the fault lasts.
- A variance appears and cannot be attributed to a person or a period.
- A shared drawer across a shift, a shared login, or both.
- Money, and then something worse than money: an untraceable variance teaches everyone that variances are not traced.
- Notes go limp and coin tarnishes within weeks.
- The drawer sits in the splash or condensation path.
- Counting time on every shift, plus a hygiene point on a surface hands move between money and cups.
- The drawer starts closing crooked or needs a shove.
- Runner wear, almost always from being closed with a hip rather than a hand.
- The lock stops engaging fully, which is a security failure that announces itself first as an annoyance.
