What is the best alternative to RepairShopr?

It depends on what you are leaving RepairShopr for. For a device-repair shop that wants repair-specific tickets, native mobile apps with no device limit and pricing set for its country, BytePhase is the closest fit. Multi-store retail chains usually shortlist RepairDesk; managed-service providers should look at Syncro; a UK solo technician can start on MyGadgetRepairs’ free tier.
