Why your fare is agreed before the car arrives
The roadside negotiation is the part of a journey nobody enjoys. Here is what replaced it.
Anyone who has stood at a junction in Accra with a bag in one hand knows the routine. You say where you are going. A number comes back. You say a different number. Somewhere in the middle a price appears, and you spend the whole trip wondering whether you did well or badly.
Topsy replaces that with a quote you see before anything is booked. The fare is computed from the route between the two points you entered, using distance and time, the class of vehicle you pick, and any stops you add along the way. It is arithmetic, applied the same way for everyone, rather than a judgement about how much of a hurry you appear to be in.
Why the quote is held
Once you have a quote, it is held for ten minutes. That window exists because deciding takes time. You might be checking whether a colleague is coming, or looking at the price of an XL against an Economy, or simply putting your shoes on. If the ten minutes lapse, the fare is recalculated in front of you rather than quietly changing underneath the booking.
This matters more than it sounds. A quote that can drift while you look at it is not really a quote, and a customer who discovers a different number at the end has learned not to trust the first one.
What actually moves the number
Four things. The distance of the route, the time it is expected to take, the multiplier on the ride class you choose, and any stops. A promo code or loyalty points come off the total afterwards. Nothing else is applied silently.
It is worth understanding the stops rule in particular, because it is where people are most often surprised. A stop is priced into the same journey rather than added later, so a trip that collects a friend in Osu on the way to Tema is quoted as the trip it really is. The alternative, which is agreeing a fare and then asking the driver to make a detour, is exactly the situation where an argument starts.
Comparing before you commit
Every ride class available on your route is priced at once and shown together, with the number of seats. This is deliberate. Choosing a vehicle and then finding out the price is the wrong order: it invites you to pick on price alone and then discover the boot is too small. Seeing them side by side lets you pick for the luggage and the group rather than guessing.
None of this makes a fare cheap or expensive by itself. What it does is make it explicable. If you want to see how the whole trip works end to end, the How Topsy works page walks through it.
