What shops actually miss when they leave an installed package
It is worth being fair about what a mature installed retail package does well, because shops that switch on marketing alone tend to switch back. Installed systems are fast, they work when the internet does not, they have deep vendor catalogue support, and they were built by people who understood a counter. None of that is trivial and none of it should be dismissed.
What they were not built for is a shop where a large share of revenue never crosses the counter at all. Rentals bill monthly. Repairs are quoted, approved and collected days later. Lessons recur weekly and are invoiced by term. Those three streams frequently outweigh retail sales in an independent shop, and they are exactly the ones a counter-shaped system models as an afterthought.
So the realistic move is not a replacement but a split. Keep something cheap and reliable at the till. Move the parts of the business that are about objects, obligations and time into a system designed around them. Shops that frame the decision that way are far happier a year later than shops that tried to find one product doing both.
