Booking-system articles for freelancers and 2–50 person teams running every part of the business themselves.
"Seven days, so seventy time options to create by hand" — a real question from Japan's largest Q&A site. Building a Chouseisan attendance sheet takes minutes. The trouble starts afterwards, and it concentrates in three places: the number of candidate times, tracking who has not replied, and who can read the answers. Here is the procedure, and what those four sticking points actually are.
There is no Chouseisan-LINE integration — you paste the URL into a chat. But since 2026 LINE chats coordinate dates natively, with the same three-way answer and an automatic tally. When each one is the right call.
"Now there is a monthly fee" — MOSH's CLASSIC plan ends on 30 September 2026. But it is not a price rise: payment fees are unchanged, and bookings and payments are both included in the FREE plan. Here is what actually matters if bookings are the core of your work.
SelectType charges 5.6% on card payments on its free plan and 4.9% on Basic — Stripe's 3.6% plus a platform cut that shrinks as you move up. Compare subscriptions alone and free looks cheapest; past a certain volume that reverses. Here is how to find your own crossover.
"A completely free booking system with everything you actually need" is the most common verdict on Air Reserve. But the free plan excludes Google Calendar sync and reminder emails — both start at Basic (¥5,500 incl. tax). Here is what those two cost in minutes per booking, and the monthly volume where paying becomes cheaper.
Scheduling and room booking take 26.5 minutes a day, and the top difficulty reported is finding a time when participants are free (72.0%). Scheduling with several people is really three problems; one question tells you which one you are in, and what ends the back-and-forth.
The conversation about building your own usually stops at whether you can. Google Apps Script publishes the numbers that actually decide it: 90 minutes of trigger runtime a day and 100 email recipients on a consumer account. Three routes, and where each one stops.
A booking form collects a request; holding the slot is a separate job. That is why so many of them end with "this does not confirm your booking". Here are the fields worth asking for, the purpose-of-use statement Japanese law wants above the submit button, and how to stop needing the disclaimer.
You confirm Thursday 14:00 on the phone, look again, and a colleague's name is already in the cell. The column design and the overlap formula that actually work, what Microsoft's own documentation says happens when two people share the sheet, and the point where the intake has to move.
"Slots come from my calendar, so nothing can collide with them." On a free Google account that is only half true — checking availability across more than one calendar is a paid feature. How to set an appointment schedule up, what free covers, and the exact configuration in which bookings still clash.
"A reply came back asking for exactly that time, and the two collided." Teams and Outlook give you three ways to settle a meeting time, and each works on a different kind of person. Scheduling Assistant, Scheduling Poll and a booking page — plus why external availability never appears at all.
"Recently there have been many cases where that email does not arrive" — a notice a dental clinic published on its own website about its booking reminders. Paste-ready templates for confirmations, reminders and cancellations, how to check whether yours are being delivered at all, and when to stop sending them by hand.
