Accra is 1 hour behind Geneva
Best overlap: 9:00 AM to 6:00 PM in Geneva is 8:00 AM to 5:00 PM in Accra.
9:00 AM to 6:00 PM in Geneva is when Accra is also working, at 8:00 AM to 5:00 PM their time. Scheduling is forgiving here: with 9 hours of overlap, a missed slot just means picking another one the same day. Just remember Geneva changes its clocks for daylight saving and Accra doesn't, so confirm the overlap whenever the seasons turn.
