“We were paying a fortune to rent software that never quite fit how we run. Fortis built us exactly what we needed, and it's ours now, not rented. Bookings and payments just work, and they're straight on it whenever we have a question.”
“The member app has been the difference for us. People book and pay from their phones, and the reminders keep them coming back. It looks and feels like our brand, not some generic system.”
“Getting the whole business onto one system, members, memberships, billing and classes, took the admin headache away. It was built around how we actually work, instead of us bending to fit the software.”
“Scheduling classes used to be a daily juggle. Now it's automatic and synced, and clients book straight through our own app. Genuinely bespoke, and delivered quicker than I expected.”
“What sold me was that it's a real, insured company you can actually get hold of, not a freelancer who disappears. They built what they said, on time, and they're still there when I need them.”
“We own our software outright, and the card processing costs us less than before. Paying once for something that's ours beat renting forever, hands down.”
