How Oakberry saves 20+ hours a week with Wolt’s POS integration

It began with a bowl of açaí on a sunny afternoon in Brazil.

Michael Drechnowicz, co-founder of Oakberry Düsseldorf, Cologne, and Westfield Centro, remembers it clearly: 

“It was sunshine, good vibes, and that incredible taste. I thought, why isn't this in Germany yet?” 

Just months later, in August 2021, Michael opened Germany’s first Oakberry in Düsseldorf’s Altstadt. Cologne followed three years later.

Behind the vibrant storefronts, though, were the challenges familiar to any ambitious restaurant:

• Keeping daily operations smooth.

• Maintaining consistent quality.

• Attracting customers year-round, especially in winter.

Why delivery was always part of the plan 

“Winters in Germany aren’t exactly friendly to foot traffic,” Michael says. “We knew delivery would be essential to sustain sales.”

From day one, Oakberry partnered with Wolt for delivery and this made a measurable impact.

• On average days, delivery accounts for about 20% of sales.

• On cold, winter days, that can jump to over 50%.

The role of delivery has only grown, fuelled by a loyal customer base, shifting habits, and the steady flow of new orders from Wolt.

Why integration mattered (and when it happened)

At first, delivery processing was a bottleneck. Orders had to be:

1. Downloaded manually from Wolt

2. Typed into the POS

3. Matched to inventory

4. Double-checked for errors

“It was tedious, time-consuming, and mistakes were inevitable,” Michael says.

The fix came with Smoothr, which connected Wolt directly to Oakberry’s Lightspeed point-of-sale (POS) system.

Now:

• Orders land as native POS items and print at the register.

• Staff prepare and mark ready on the same screens they already use.

• Bookkeeping is cleaner, with one verifiable record for every delivery.

• Stock stays in step: because items and modifiers map into Lightspeed, end-of-day sales totals — and, if inventory tracking is enabled, stock counts — update from the same source, without manual matching.

“Orders placed on Wolt now go straight to our Lightspeed system and print at the register,” Michael says. “Staff see the order on screen and mark it ready. That saves a huge amount of time, especially when delivery is busy. It also simplifies bookkeeping and tax reporting; we can prove every Wolt order came through the interface.”

The impact is tangible:

• 20+ hours saved per store each week

• Order corrections dropped from ~5% of sales/month to 0%

Data that drives better decisions

The automated integration gave Oakberry more than just saved time; it gave them strategic insights.

“We used to manually merge Wolt and POS reports and often lost historical data,” Michael explains. “Now, we can instantly see patterns, like which toppings sell best at different times of day.”

These insights help with:

• Stock planning: time-of-day topping trends inform daily prep lists, so popular additions are ready when they’re most likely to be ordered.

• Staffing: managers align coverage to windows when the delivery mix typically climbs (e.g., during colder or rainy periods), so the line stays calm when the app is busy.

• Menu review: item-level performance tracked over weeks and months supports ongoing menu reviews, what to keep as-is and what to simplify, based on real ordering behavior.

And quality control?

“We worried about delivering açaí bowls at the right consistency. But with perfected packaging and Wolt’s reliable drivers, customer satisfaction is high.”

Growing visibility with Wolt Ads

Oakberry discovered another powerful lever: Wolt’s advertising tools.

Wolt campaigns brought tangible, lasting results.

Michael shares, “Campaigns like two-for-one promotions consistently attract first-time customers, who then return with friends. After running these campaigns, we often see new customers becoming regulars and signing up for our loyalty card.”

Growing with calm and confidence

Today, Oakberry continues to expand confidently, recently opening their largest German store in Westfield Centro Oberhausen. Michael credits much of this confidence to the operational backbone created through their partnership with Wolt.

“The integrated system allows us to scale without overwhelming our teams,” he notes. “The time we save and the accuracy we gain give us confidence to expand aggressively, something impossible if we were still bogged down with manual processes.”

Michael’s advice to fellow restaurant owners

Michael encourages other restaurateurs to focus on operational excellence and customer connection:

“Choose partners carefully. Great partnerships are those that simplify operations, enhance customer experience, and genuinely care about your growth.”

He concludes:

“Building Oakberry has taught us that successful expansion depends heavily on reliable systems and strong relationships. Those are your true keys to growth.”
