Choosing appointment booking software means deciding once and not thinking about it again for years. This guide gives you a twelve-point appointment software checklist, the questions to ask in a demo, the red flags in the pricing sheet, and a plan for a two-week test. It works for any provider, whichever one you end up choosing.
Start with your day, not with the feature list
Most comparisons begin with a table full of ticks. That is the wrong order. Start with your business: How do your customers book today? How many people hand out appointments? Which services keep falling through because nobody turns up? And is the phone a problem because it rings while you work? Four answers become a list of what the software actually has to do.
A solo business with twenty appointments a week needs something different from a studio with six staff and a shift plan. If your customers come from Instagram, you need a link that works on a phone. If you book long Saturday slots, you need deposits. Write your answers down before you book the first demo. Otherwise the feature that looks best wins over the one you use every day.
- How do appointments come in today: phone, WhatsApp, Instagram, walk-in?
- How many people book appointments and need a calendar of their own?
- Which services regularly fall through and would justify a deposit?
- How many calls go unanswered because you are working?
Choose appointment booking software: the first six criteria
The first half of the checklist is about customers and staff. The most important criterion comes first: your customers must not need an account or an app. Every sign-up costs bookings, especially from people booking with you for the first time. Right after that comes availability: the page may only show times that are genuinely free in the calendar. Otherwise you cancel, and that customer never books online again.
Reminders are the third criterion, and here the price deserves a second look. Some providers charge for every message, on WhatsApp just as on SMS. With five hundred appointments a month and two reminders each, that adds up. So do not only ask whether reminders exist, ask what each one costs. At terminio, WhatsApp reminders are part of the plan, with no fee per message.
- Customers book without an account or an app, just a name and a mobile number
- The booking page shows live only the times that are really free in the calendar
- Reminders by WhatsApp, with a clear answer on the cost per message
- Deposits per service, not just a blanket rule for every appointment
- A calendar for each staff member, with working hours and holidays
- Apps for phone and watch, so you see appointments without going to a computer
Appointment software checklist: data, price and contract
The second half checks what you cannot see in a demo. If you lose calls, ask whether there is a phone option, such as an AI assistant that answers and books straight into the calendar. Then the data: customer names and mobile numbers are personal data. The software should host in the EU and give you a data processing agreement without you having to chase it. This is orientation, not legal advice, but it is the baseline the GDPR generally requires.
On price, the model matters more than the number. A flat monthly fee is predictable. A fee per booking or a commission on every appointment grows with your success and punishes you for full days. Marketplaces that lead your customers to competitors on the same page are not a booking system, they are a middleman. And finally: how long does setup take, and how fast can you leave?
- A phone option: an assistant that answers and books straight into the calendar
- Hosting in the EU and a data processing agreement without chasing
- A flat monthly price, no fee per booking, no commission
- No marketplace that puts your customers next to your competitors
- Setup in an afternoon, not a project with a consultant
- Cancel monthly, with no minimum term and no setup fee
What to ask in the demo
A demo shows you what the provider wants to show. Your questions show you the rest. Ask them in this order, and have every answer demonstrated on screen, not just described. If the salesperson dodges a question, the dodge is the answer. For each question, note whether you saw the feature or only heard about it.
Red flags usually sit in the pricing sheet, not in the conversation. Commission per appointment, setup fees, a twelve-month minimum term, fees per message. Each one on its own is a reason to keep looking. Two together are a no. That applies to appointment software for small businesses advertised as free, too: the bill then tends to hide in the commission or the marketplace.
- Show me how a customer books on a phone without registering
- What does one WhatsApp reminder cost, and what do five hundred a month cost?
- Where is the data stored, and where do I find the data processing agreement?
- What happens to my appointments and customer data if I cancel?
- Is there a commission, a setup fee or a minimum term?
Test for two weeks before you decide
No demo replaces two weeks of real operation. Almost every appointment tool for small businesses has a free tier or a trial. Use it with real services, real hours and real customers, not test data. In the first week you and your team book; in the second week ten regulars get the link.
At the end of the two weeks, answer three questions. Did every customer complete a booking without asking for help? Did every free slot shown match the calendar? Did every reminder arrive? If any answer is no, find the cause or switch providers before you pay for a year. At terminio the test runs on the Free plan with 50 bookings and five WhatsApp reminders a month, with no payment details.
- Day 1: enter services, durations, prices and working hours
- Days 2 to 5: book yourself, from a phone, on a device that has never seen the page
- Days 6 and 7: test a reminder and a deposit on an appointment of your own
- Week 2: ten regulars book through the link while you listen
- Day 14: answer the three questions, then decide
Switch without losing a single appointment
A switch rarely fails on technology; it fails on timing. Pick a cut-off date four weeks out. Until then the old system keeps running, and every new appointment after the cut-off is entered in the new one from the start. That way there is never a day when two calendars know the truth, and no customer gets asked twice.
Before that, export your customer list with names and mobile numbers, usually as a CSV. Existing appointments for the coming weeks you enter by hand in the new system; for a small business that is one to two hours. Then swap the link in your Google profile, your Instagram bio and your website, and cancel the old system as of the cut-off date. If it cancels monthly, you lose at most one month.
