How Groucho's Deli Ran 39,000 Online Orders in 10 Weeks After Moving to Per Diem
TLDR
Groucho's Deli has been making sandwiches since 1941. Harold "Groucho" Miller opened the first shop in Columbia, South Carolina, with his own recipes for dressings, potato salad, and coleslaw. Today the brand has 32 locations across South Carolina, North Carolina, and Georgia.
Groucho's already had online ordering. It worked. It just wasn't built for where the brand was going. After moving app, web, and catering ordering to Per Diem, Groucho's ran 38,948 online orders in the first ten weeks, with online revenue up 6.0% over the same dates a year earlier. More guests. More orders. Same sandwich. Here's what changed.
Why Groucho's Left Its Legacy Platform
This wasn't a first try at online ordering. Groucho's had a platform, and it did what it was built for: take the order and send it to the kitchen. What it didn't do was grow with the brand. As Groucho's added locations and guests changed how they ordered, the system stayed where it started.
Groucho's started franchising in 2000 after decades as a single shop. Every location has to serve the same sandwich the same way while still feeling like the neighborhood deli it is. The online experience has to hold that same line.
"We adapt, we don't change. The sandwich is the sandwich. What had to change was how our guests get to it. We needed web, app, and catering to run as one experience, on one omnichannel menu, tied straight into Square. That's what we built with Per Diem."Deric Rosenbaum, President and CTO, Groucho's Deli
The timing lines up with the industry. Square reports that 78% of restaurant owners say online ordering drives more orders than any other channel, and that first party ordering carries better margins than third party delivery.
Groucho's guests already knew the brand and the Formula 45. The job was giving them a simpler way to order directly.
Making Groucho's Easier to Order
Most of the brand's digital orders are pickup and ASAP. That fits how people use a deli. Grab lunch between meetings. Pick up dinner on the way home. Choose the food, place the order, and know when it's ready.
The branded web storefront and mobile app make that possible. Automated status messages keep the guest informed from the moment the order lands until it's ready at the counter.
38,948 Orders in the First Ten Weeks
From launch on July 13 through September 21, Groucho's processed 38,948 online and app orders, up 5.6% from the same dates a year earlier on the old platform. Online revenue rose 6.0% over the same period.
The transition was phased, with full cutover on July 28. In the 56 days after that, Groucho's ran 31,002 orders. Against the same dates a year earlier, online revenue was up 7.9%, order volume was up 7.5%, and trackable guests were up 9.6%. Every measure picked up once the old platform was fully retired.
The Groucho's app has 7,706 total downloads across iOS and Android since launch. The app gives guests a fast way back to their usual order. The web storefront carries an even bigger share. Guests go from Groucho's website to a placed order without installing anything. Two channels. Guests pick the one they want.
"The growth is coming from more guests placing more orders. Average check is flat at about $25.00. That's the result we wanted. We didn't get here by pushing bigger tickets. We got here by making it easier to order a Groucho's. Higher AOVs come next."Deric Rosenbaum
That choice matters. Square found 60% of guests probably wouldn't return to a restaurant without convenient ordering and payment. Groucho's ASAP pickup numbers say the same thing. When guests want their usual fast, they come to Groucho's direct channels.
How Groucho's Keeps Guests Coming Back
One order is useful. A second order is the business.
Today 29% of Groucho's online guests are repeat guests, and that group grew 24% month over month in the latest period measured. A meaningful share of the online base is building a habit.
"And we're just getting started on this platform."Deric Rosenbaum
The guest base is growing too. Groucho's has had 24,887 trackable online guests since launch, up 8.3% from 22,981 a year earlier. Since the full cutover, that growth rate has run at 9.6%. More guests are ordering directly, and more of them are coming back.
Groucho's stays in front of guests after the order. Offers run on a regular cadence. In app banners and posts highlight offers, menu items, and rewards. The brand reaches people who have already ordered instead of waiting to be remembered.
The discount rate stays lean on purpose.
"We don't buy the second visit. We earn it. The tools give us a reason to say hello again. The sandwich does the rest."Deric Rosenbaum
Catering Gets Its Own Lane
Catering is a different guest with a different need, so Groucho's runs it as its own channel.
With Per Diem, catering is a separate ordering option and a separately tracked line of business. A 40 person office lunch no longer gets lumped in with Tuesday's counter orders. The team sees catering clearly and manages it on its own terms.
For a deli, that's the right call. The menu was built for group meals, business lunches, and events. Now those guests have a clear path to place a big order, and Groucho's has a clear view of that business.

When a Restaurant Has Outgrown Its Ordering Platform
A system can still process orders correctly and still hold the business back.
Older platforms focus on moving an order from the guest to the kitchen. That gets restrictive once you want to know who comes back, run targeted offers, build an app audience, grow catering, or manage guest activity across 32 locations.
Separate tools for each job create a second problem. Ordering here, marketing there, catering somewhere else, guest data in four places. You end up with pieces of the guest relationship and no view of the whole thing.
The better question isn't whether the current system still works. It's this: what can the business do with a guest after the order is placed?
Final Thoughts
Groucho's had 85 years of brand recognition before this move. Per Diem gave the brand a way to bring the next stage of online growth in house.
"Ten weeks in, we've run close to 39,000 orders through the new platform. Online revenue is up 6.0% year over year, and since the full cutover, it's running at 7.9%. Trackable guests are up 8.3%. Repeat guests are 29% of our online base and growing. More importantly, it all runs on one omnichannel menu through Square, so every location sees what our guests see. That's the foundation. Everything else builds on it."Deric Rosenbaum
For restaurants still on an older ordering system, the lesson is simple. The value of online ordering doesn't end when the order hits the kitchen. What happens with that guest afterward matters just as much.
