If you have two chairs and three staff, here is the short list of what matters.
Software companies sell salons a long feature list. Owners then pay for twenty things and use four. Here is the honest short list.
Billing that is faster than a notebook. If it takes longer than writing it down, your staff will stop using it by week two. A customer list you own. Name, phone, what they took, when they came. This is the most valuable thing your business has. Staff numbers. Who did what, and how much each person brought in. Without this you cannot pay commission fairly. Stock that warns you before it runs out, not after a client is already in the chair.
Multi-branch dashboards, if you have one branch. Complicated marketing tools. A well-kept phone list and a message beats them. Anything that needs a trained person to operate.
Can your newest staff member make a bill on it, alone, in under a minute? Does it work on a phone when the counter computer is busy? Can you get your customer list out again if you leave? If not, walk away. Does it work when the internet drops for ten minutes?
TrackMyGlow for Business is built for the two-chair parlour first and grows if you do. Free to start. Once a paid plan is bought there are no refunds, so use the free version until you are sure.
Test it with your newest staff member, not with yourself. Make sure you can export your customer list. Ignore any feature you would not use this month.
The one your staff will actually use at the counter. Speed of billing and a customer list you can export matter far more than a long feature list.
You should not need it constantly. Ask specifically what happens during a ten-minute internet drop before you commit.
