# Switch from paper appointment book Source: https://terminio.ai/en/ratgeber/from-paper-diary-to-online-booking · Updated: 2026-09-06 What the paper book does well, what it cannot, and how to switch in four weeks without losing an appointment. The paper diary has carried you through the day for years. It is fast, sits on the counter and needs no password. But it is closed in the evening, reminds nobody and cannot be in two places at once. This guide shows how to run a digital appointment diary instead: what changes, what stays, a four-week plan, and the numbers to check afterwards. ## What the paper appointment book does well, and what not The appointment book on the counter is not a bad tool. It is there instantly, with no battery and no login. One glance shows the whole day, one stroke cancels an appointment. Someone new to the team understands it in a minute. That is exactly why so many salons, practices and workshops hold on to it for so long: it has never failed, at least not visibly. Invisibly, it fails every evening. At seven someone wants an appointment, and the book is lying in a dark shop. It reminds nobody about tomorrow morning, so the chair stays empty when a customer forgets. It cannot be on the counter, in the treatment room and at your home at the same time. And if coffee goes over it or it goes missing, the month is gone. A digital appointment diary keeps the strengths of paper when it is done well: one glance, one tap, no waiting. On top comes what paper never could: customers book at night, reminders go out on their own, and the calendar is the same on every device. That combination is the point, not the technology. ## Digitising the diary: three worries, answered honestly The first worry is control. In the book you decide who comes when. Online, strangers book into your day. The honest answer: you give up less than it feels like. You decide which services can be booked, how long they take, where the breaks are and how short notice is allowed. The calendar only shows what you have released. The second worry is older customers. They keep calling, and that is fine. You enter the appointment yourself, in ten seconds, as you did with the pen. Nobody has to install an app or create an account, neither on the phone nor when booking through the link. The only difference is where the appointment gets written down. The third worry is staff who like paper. Behind it is usually a fear of extra work. The answer is a trial: two weeks of both, then ask what was easier. Anyone who has once seen their day on their phone without walking to the counter rarely wants the book back. ## Replacing the paper diary in four weeks: the plan The mistake in most switches is the cut-off date: book on Friday, software on Monday, a weekend in between. It goes wrong because on Monday the old appointments are missing and the team does not know the new routes yet. Four weeks with one clear job per week work better. With terminio.ai, name, services and opening hours are set up in a few minutes, and the rest of the first week is getting used to it. Week two is the one that matters. Running both costs a few minutes a day, but it exposes every mistake before it reaches a customer: a service set too short, a missing break, a colleague who does not work on Wednesdays at all. What shows up in week two is fixed by week three. - Week 1: set up services with duration and price, enter opening hours and breaks, add the team with colours - Week 2: run both in parallel, every new appointment in the book and in the calendar, compare each evening - Week 3: show regulars the booking link at their visit, enter their next appointment digitally right away - Week 4: close the book, only the calendar counts, one last comparison on Saturday ## How to carry over the next eight weeks The book holds appointments far into the future: the perm in three weeks, the check-up in six, the tyre change in autumn. You do not have to type them all in on day one. Take the next eight weeks, which is enough for the transition. Everything later you carry over week by week, always one week ahead of where you are. Allow about a minute per appointment if name, number and service are legible. At 30 appointments a week, eight weeks is a quiet afternoon. Split the work across the team: each person transfers their own column, because they know their handwriting and their customers. In the end every transferred entry in the book has a tick next to it. - Type in the next eight weeks, leave older pages alone - Per appointment: customer, mobile number, service, person, time - Tick every transferred entry in the book - Ask for missing numbers at the next contact, otherwise there is no reminder - At the end, compare book and calendar once, page by page ## A digital diary for salon and practice: counter, room, wrist At the counter, the phone or tablet replaces the book. The day is a list, one tap opens the appointment, a second moves it. What was a stroke in the book is now a swipe. Anyone with a customer on the phone sees the free slots without leafing through pages and enters the appointment while still talking. In the treatment room or the workshop, looking at a phone is often impossible: hands are full or not clean. That is where the watch helps: the next appointment sits on your wrist, with name and time. The terminio app runs on iPhone, Android and smartwatch, and everyone in the team sees the same state, whatever the device. For the team, less changes than they fear. Each person sees their own day, with customer, service and time. Prices and customer data stay with you. The walk to the counter goes, and so does the asking around. What you change in the morning, everyone sees the next time they look at their phone. ## What stays on paper, and which numbers count The short answer: nothing. A second system next to the calendar is the back door through which the old book returns. One exception is allowed: in the first weeks a printed day plan may lie next to the till in the morning if it helps the team. After four weeks nobody asks for it, and you drop it. After a month, look at four numbers. They tell you whether the switch is paying off and where to adjust. Any decent software shows them, usually under statistics. If bookings after hours stay near zero, the link is not visible enough. If no-shows do not fall, check whether the mobile numbers made it into the calendar. - Share of appointments booked outside opening hours - Reminders sent, and how many appointments still fell through - Appointments customers moved or cancelled themselves, without calling - Calls per day, compared with before the switch ## In short - The short answer: Keep what the book does well, one glance and one tap, and add what it cannot: booking after hours, automatic reminders, the same calendar on every device. Nothing stays on paper. - The number to remember: Four weeks: set up, run both, move the regulars, close the book. Plus eight weeks of existing appointments to carry over, at about a minute each. - The next step: Enter your services with duration and price and your opening hours today. From tomorrow, write every new appointment in both places and watch what the calendar shows that the book did not. ## Common questions **What happens when the internet goes down?** Your calendar lives on the provider's servers, not on one device, so a dead router loses nothing. The phone keeps working on mobile data, and the day's list is a quick look in the morning. In practice the outage is rarer than the coffee over the book. **Do my customers have to book online now?** No. Anyone who wants to call still calls, and you enter the appointment as before, just into the phone instead of the book. Anyone using the link needs neither an app nor an account. Both routes land in the same calendar, and both get the same reminder. **How long does transferring the old book take?** Allow about a minute per appointment with legible handwriting. Eight weeks at 30 appointments a week is roughly four hours, and much less once it is spread across the team. Anything further out than eight weeks you carry over week by week. **What does a digital appointment diary cost?** Depending on the provider, between nothing and a monthly fee. With terminio.ai the free plan includes the booking page, the calendar and unlimited staff, plus 50 bookings and five WhatsApp reminders a month. No setup fee, cancel monthly.
