Adding a convenience store to an existing gas station that never had one is one of the highest-ROI investments in fuel retail. This case study shows how Petrol Group executed this project from zero.
Starting point
Existing station: 6 pumps, no c-store, a small office only. Available footprint: 45m² adjacent to the existing office. Monthly fuel volume: 310,000 liters, all revenue from fuel only.
Design approach
The c-store layout maximized the 45m² space: refrigerators at the back wall, coffee station visible from the entrance, cash counter intercepting exit flow. Full-height glass facade facing the forecourt to maximise visibility from pumps.
Results
C-store revenue at month 3: BRL 62,000/month. Gross margin: BRL 24,000/month. Payback on BRL 110,000 investment: 4.6 months. Fuel volume increased 11% — the store brought customers who also refueled.
