The Challenge

€50K/Month Drain, No Control Over Franchises

FeinFood is a successful food brand in Germany with multiple franchise locations and a network of vendors. Over the years, the growth had outpaced their infrastructure. Each FeinFood's vendor operated on different software. Each franchise location had its own fragmented workflow. There was no unified view of operations just a patchwork of disconnected tools held together by spreadsheets and WhatsApp groups.

The cost of an estimated €50,000 per month from revenue was lost. All of this because of vendor miscommunication, order duplication, delayed stock replenishment, and franchise locations operating blind, unable to access real-time data about their own performance.

FeinFood mentioned that previous agencies proposed more integrations between existing tools. Freelancers had built partial solutions that created more problems than they solved. What our client needed wasn't another integration but a single platform that replaced the entire fragmented stack.

No Central Vendor Control
Multiple vendors using different systems. No centralised ordering, no unified communication, no real-time stock visibility.
No Franchise Tools
Franchise managers had no mobile access to operations data. Every decision required manual lookups or phone calls to HQ.
€50K/Month Drain
Revenue loss from order errors, vendor delays, stock mismatches, and operational overhead consuming management capacity.
The Solution

Three Platforms Built from Scratch Equals Zero Chaos

We didn't patch the old systems. We replaced them entirely, designing and building three interconnected platforms that give FeinFood complete control over their vendor network, franchise operations, and customer-facing commerce.

Platform 1
Vendor System Made Simple
One platform handles ordering, pricing, and stock for everyone. Vendors use their own login. FeinFood can see and manage it all.
Platform 2
Franchise Management App
Created a native mobile application (Flutter) for franchise managers for real-time sales data, inventory alerts, vendor ordering, performance dashboards. All from their phone.
Platform 3
Centralised Admin Panel
Master admin dashboard for FeinFood leadership cross-franchise analytics, vendor performance, revenue reporting, and operational controls. One screen, full picture.

The platform TrestleCart built didn't just solve our vendor problem, it became the backbone of our entire franchise operation. We went from managing chaos to managing growth.

Key Takeaway

Too many tools may slow you down. One system moves you forward.

FeinFood's breakthrough wasn't a single feature or a clever integration. It was the decision to stop patching and start building, to replace a fragmented ecosystem with a unified platform designed specifically for how they operate.

Three interconnected platforms by TrestleCart (eCommerce, mobile app, admin panel) replaced dozens of disconnected tools. The €150K/month revenue swing — from losing €50K to gaining €100K — is the financial proof. But the real transformation was in the founder's day: from firefighting vendor problems to planning the next market expansion.

Eight months later, FeinFood is still on retainer with us. The platform evolves as they grow. That's what a structural partner does.
