# Add a Walk-in Line to Your Booking App | NextUp Walk-in Source: https://nextupwalkin.com/blog/add-walk-in-line-to-booking-app > Keep your booking app for appointments and add a real walk-in line beside it: who takes walk-ins, honest waits and the door sign. Operations # Keep your booking app, add a walk-in line Your booking app runs the calendar, your regulars know the link, and moving years of client history is the last thing you want to do this month. But people still walk in, and the booking app has no good answer for them. You do not have to switch to fix that. Here is how to run a walk-in line beside the booking app you already use, without the two stepping on each other. [Blog](https://nextupwalkin.com/blog) [By Nicholas Chadwick](https://nextupwalkin.com/about)·Updated October 25, 2026· 7 min read ## Why the booking app’s waitlist is not a walk-in line Booking apps are built around the calendar, and their waitlists are too. In most of them, a client joins the waitlist from the booking site and gets a notification when an appointment slot opens up. That is a list of people hoping for a future slot ([see how the main booking apps compare](https://nextupwalkin.com/compare)). A walk-in is different. They are at your door, or ten minutes away, and they want to be seen today. They need three things the calendar does not give them: a place in line, an honest wait, and a way to step out without losing their spot. That is a line, not a booking, and it can sit beside your booking app without replacing it. ## Who this setup is for It fits a shop that books most of its work but still gets walk-ins: a barbershop with a few chairs open on Saturday, a salon where a blowout or a fringe trim shows up unannounced, a nail salon with a “walk-ins welcome” sign, a tattoo studio that takes small pieces between booked sessions. It also fits an owner who is thinking about switching apps but not yet. Running the line first is a low-risk way to see how many walk-ins you really get, and when, before you make any bigger decision. Our guide to [walk-in vs appointment](https://nextupwalkin.com/blog/walk-in-vs-appointment) covers how to decide which work belongs on which side. ## Step 1: decide who takes walk-ins, and when Most clashes between a book and a line come from one question nobody answered: who is supposed to serve the walk-in? Pick one of three set-ups and write it down. **Walk-in chairs.** One or two people take walk-ins only, and everyone else works from the booking app. Simplest to run, and the wait is easy to quote. **Walk-in hours.** Everyone takes walk-ins in set hours, for example weekday mornings and Saturday until 2, and bookings fill the rest. Good when walk-ins bunch up at predictable times. **Gaps.** Walk-ins go to whoever has a gap long enough for the service. The most flexible option, and the hardest to quote honestly, so it needs the habits in step 3. Whichever you pick, booked clients keep their time. A walk-in is told the honest wait and chooses to stay or come back; nobody who booked gets bumped for someone who did not. ## Step 2: put the line where people already arrive The door is the walk-in’s front desk. Put a QR code on it with one line of text, such as “Walking in? Scan to join the line and see the wait.” Customers join from their own phone with no app to download and no account, and see their place and a live wait. A tablet by the door running the Door Tablet screen catches anyone who would rather tap than scan. Online, keep two links and say what each one does. Your booking app’s link is “Book ahead”. Your line link is “Walk in today”. Put both in your Instagram bio and on your Google Business Profile, where the profile allows it; our [Google Business Profile guide](https://nextupwalkin.com/blog/google-business-profile-walk-in-shop) has the steps. Two clear doors beat one confusing one. ## Step 3: keep the walk-in wait honest around booked clients NextUp Walk-in does not read your booking app’s calendar. That is the one thing to plan around, because a wait quote that ignores a booked 2 o’clock is a quote you will break. Use who is on duty as the switch. On the Staff Screen, “Who’s working today” marks each person on or off duty. Only people on duty are in the rotation when staff press Call next, and the wait estimate is divided across them. When a stylist starts a booked block, tap them off duty; when the block ends, tap them back on. The quote moves with it. Let customers choose who they see, if requests matter in your shop. The Check-in Page then shows each team member who is working with their own wait, plus “First available” for anyone. Someone who wants a particular barber sees that his afternoon is mostly booked and can pick “First available” instead. Add your services with their real times. A wait built from “beard trim, 15 minutes” and “color, 90 minutes” is far closer than one built from an average. Our guide to [estimating walk-in wait times](https://nextupwalkin.com/blog/how-to-estimate-walk-in-wait-times) shows the math. Pause the line when the book fills up. The Open or Closed toggle on the Locations page, or on the Staff Screen, stops new people joining online and keeps everyone already in line. A Saturday that turns out fully booked by noon is a two-second fix, not a lobby full of people you cannot serve. ## Step 4: let walk-ins wait somewhere else A walk-in who can see their place on their phone will get a coffee instead of standing at your front desk while your booked client checks in. Their page shows the moment it is their turn, and staff can ask “Still coming?” from the Staff Screen, which they answer with how far away they are. When the wait is over 10 minutes, the Check-in Page offers “Tell me when the wait is shorter” by email, and once a location has a few weeks of visits it shows the best time to come today. Text alerts switch on soon, once carrier verification finishes; until then customers follow their place live on their phone. If you have a TV in the waiting area, the TV Display shows who is next on every plan, Free included, so booked clients and walk-ins can both see the order without asking. ## Step 5: check the numbers after two weeks After two weeks, open Insights. It shows walk-ins per day, a heat map of your busiest hours and days, and how close quoted waits came to the real ones. If walk-ins bunch up on Saturday mornings, that is your case for a walk-in chair on Saturdays. If quotes run short, the services in step 3 need longer times. You may find the line pays for itself and the booking app stays exactly where it is. Or you may find that running two apps is more work than one. NextUp Walk-in’s Pro plan has online booking and a team calendar too, so the book and the line can live in one app if you want that later. There is no rush to decide. ## What it costs, and what it does not do NextUp Walk-in does not connect to other booking or point-of-sale systems. You run them side by side: bookings in your booking app, the walk-in line in NextUp Walk-in. Checkout can stay where it is today; NextUp Walk-in can take payment for a visit too, but it is not a full POS. The walk-in line, the Check-in Page and the Door Tablet come with every plan, Free included. The Walk-in plan is $29 a month for your first location and $19 for each one after, with 3 team members included per location, then $10 a month each. Online booking is on Pro, at $59 and $39. Every paid plan starts with a 14-day free trial (once per business) that has every Pro feature. A card is needed to start, but nothing is charged until the trial ends. See [pricing](https://nextupwalkin.com/pricing) and how NextUp Walk-in compares on the [comparison pages](https://nextupwalkin.com/compare). There is also a Free plan: 1 location, 1 team member and 50 check-ins a month, with no texts and no card needed. ## Questions ### Can I keep my booking app and still take walk-ins properly? Yes. Keep the booking app for appointments and run a separate walk-in line beside it, with a QR code at the door and a live wait on the customer’s phone. ### Does NextUp Walk-in sync with my booking app’s calendar? No. It does not read other booking apps. Mark people off duty during their booked blocks so the walk-in wait stays honest. ### Isn’t my booking app’s waitlist the same thing? Usually not. Most booking apps’ waitlists tell clients when an appointment slot opens. A walk-in line is for people who want to be seen today. ### Which NextUp Walk-in plan do I need for just the walk-in line? The Walk-in plan, $29 a month for your first location. Online booking is on Pro, if you later want everything in one place.
