PepperJack Sandwiches is built for speed, precision and serious sandwich game. Founded by husband-and-wife duo Henry Wong and Michelle Yoon, the shop turns out hundreds of orders a day. Inspired by the flavour-packed style of San Francisco’s iconic deli sandwiches, each creation features golden, crusty breads and thoughtfully layered fillings made to satisfy without compromising on taste. So, what does it take to keep pace with that kind of demand? Henry takes us through his South Brisbane joint to show how it all works behind the scenes.
And if you’re hungry for more, read PepperJack’s full story – from bold ideas and early hurdles to a bustling sandwich spot.
On the counter
PepperJack runs a streamlined setup built for a tight-knit crew. In-person orders are handled smoothly with Square Register, with its customer-facing screen, and the portable Square Terminal for flexibility.
Square Kiosk plays a huge part in how the shop handles volume. With as many as five self-serve kiosks, multiple customers can place orders at once, helping cut queues and lighten the load on staff. This setup enables the team to keep up a rapid pace, even when the lunch crowd is at its peak.
“The kiosks really take a lot of pressure off the staff,” says Henry. “With the kiosk, there’s no line now. Five or six people can order at the same time. It’s dramatically increased efficiency. It increased our max sandwich capacity at lunchtime by maybe 30%. We could do 30% more with the same amount of time.”
Everything’s connected – customers can also order ahead via PepperJack’s Square Online store and choose a pickup time that suits them. And with Square Loyalty in the mix, regular customers enjoy perks that add extra value to each visit. The overall result? Fast, consistent service in a busy space without needing to juggle separate systems. It’s all one flow.
The business has grown with Square as its added more features. That’s probably the coolest part. It’s basically everything we needed.”

Behind the counter
All in-store and online orders automatically route through to Square KDS (kitchen display systems), which the team rely on to make the sandwiches. Screens are set up at key stations: one by the fryers and two along the sandwich line. Since every sandwich goes through a conveyor oven, paper tickets aren’t an option – they’d burn. Instead, the digital screens show real-time orders, which keeps things organised and in sync across the area.
Prep is split across two stages. First, bread, cheese and meat go through the oven. Then, on the other side of the line, sandwiches are assembled and finished with salads and sauce. At the same time, a sticky label is printed automatically for each item as soon as orders come in. One label goes on the sandwich wrapping, the other on the takeaway bag, helping staff track, pack and hand off orders quickly and accurately.
“Hands down, my favourite thing is the way [Square] looks and the way the tickets look,” says Henry. “On all other products, they just don’t look as nice as the Square ones – the tickets don’t really have any formatting on them. The customer sees the ticket, so I like how it looks nice. And just overall, the way the products are designed, it’s very slick.”
