A café is close to the worst possible business for card fees, and it is worth being precise about why rather than just repeating that fees are annoying.
Your average transaction is small, so any fixed element of the fee lands disproportionately. Your volume is enormous, so a percentage compounds fast. Your margins are thin, because coffee and rent and wages are what they are. And nearly everything is paid by card, because nobody carries cash for a flat white.
Twelve pence on a four pound coffee. A hundred and fifty coffees a day. Six days. Fifty weeks. About six and a half thousand pounds a year, which is a part-time member of staff you are not employing.
The queue is the other constraint
Anything that slows the counter at half past eight is unusable, regardless of what it saves. This is the reason a lot of clever payment ideas have never reached hospitality: they cost three seconds each, and three seconds times a morning rush is a queue out of the door.
Which is why the gesture matters more than the technology. A tag on the counter, a phone held against it, approved with a thumb. Same motion as a card, same speed, no explaining.
If it is slower than tapping a card, it does not exist as far as a café is concerned.
Where a café gains beyond the fee
- Saturday's money on SaturdayYour best two days become usable cash on those days rather than the following Tuesday, which matters when the roaster invoices weekly.
- The stamp card that counts itselfBuy nine, tenth free — counted from real settled purchases, with nothing to stamp and nothing for a regular to leave in another coat.
- Regulars you can actually recogniseNot by name, and not by anything they hand over. The same wallet paying for the ninth time is recognisably the same customer, which is the thing a paper card never told you.
- Beans and retail on the same booksWholesale bags, a bean subscription and the counter all recorded together rather than in three places.
The wholesale side, which is quietly the bigger number
A café that also roasts, or supplies offices and other shops, has a second business with completely different payment problems: invoices, thirty-day terms, chasing, and the occasional customer who treats your terms as a suggestion.
A £2,300 trade invoice paid by card costs you forty-six pounds in fees. Paid directly it costs a fraction of a penny and lands the same afternoon. On the wholesale side the fee saving per transaction is far larger than anything happening at the counter, and the cash-flow effect is larger still.
Realistic about adoption. Nobody is turning off their card machine, and most of your customers will keep tapping a card for a long time yet.
This sits alongside, costs about thirty pounds of hardware, and catches the customers who would rather pay directly. On the wholesale side it is worth pushing harder, because those customers are businesses and the amounts are large enough to care about.
And the bookkeeping, which is the bit you hate
Hospitality has a particular accounting mess: mixed VAT rates on almost every sale. Hot drinks standard-rated, cold takeaway food zero-rated, eat-in different from takeaway, retail bags different again.
Getting that right per line, at the point of sale, is the difference between a VAT return you can defend and one you have reconstructed from a spreadsheet in January. It happens as the payment lands rather than afterwards, which is the only time it can be done accurately.
Till, invoices, stamp cards and the VAT return in one place, with no cut taken from anything you sell.
