When cash goes, two things happen at once: fewer customers tip because the prompt is easy to skip, and the tips that do arrive are taxed, delayed and pooled through payroll. The first is fixable; the second is mostly the law catching up.
What shops report after going card-only:
| Change | Typical effect | Fix that worked |
|---|---|---|
| Tip prompt on the terminal with %, not amounts | Tips down 20–40% | Show amounts (50c, €1, €2) and put the "no tip" button last, not first |
| Terminal facing the barista | Customers feel watched; tip less | Turn it to face the customer and step back |
| Tips paid monthly with wages | Staff feel it disappeared | Pay tips weekly, show the total on the staff board |
| Tips taxed | Net down 20–30% versus cash | Nothing; cash tips were often untaxed and that was the risk |
| Service charge instead of tips | More predictable, sometimes higher | Must be transparent about who gets it and how much |
Things that raised card tips back up in members' shops:
- A one-line sign at the till: "Card tips go 100% to the team, split by hours." Customers tip more when they know it is not the owner's.
- Staff saying the customer's drink back with eye contact before the terminal appears. It sounds obvious; the shops that measured it saw 10–15% more tipping.
- A QR "buy the team a coffee" link for regulars who never carry cash.
Owners: did card tips end up higher or lower than cash after a year, once you count everything? Baristas: was the weekly total ever shown to you, and did it match?
