A QR call waiter app with no hardware to buy

If you want guests to call the waiter without buying table buttons, the simplest setup is a QR code on each table that opens a call button on the guest's own phone, and an alert that reaches your team on the phones or tablets they already carry, showing which table called and how long it has been waiting. That is what Sirvo does, and Sirvo is who wrote this page. Guests don't download anything, and you start with one month free, no card required. Below: how it works, how it compares with the other ways of calling a waiter, and when it is not worth it.

How it works

  1. Each table gets its own QR code, plus a 6-digit code for guests who would rather type it. Nothing to plug in or charge on the table.
  2. The guest scans it and the menu opens in the browser, with "Call the waiter" and "My bill" at hand. No app to download and no account to create.
  3. Your team sees it on the Table radar: a live floor plan of your restaurant, patio and upper floors included, where the tables asking for attention or for the bill light up with how long each has been waiting. It runs on the phones and tablets you already own.
  4. Someone goes, marks it as handled, and the table goes quiet again, so the list never fills up with old calls.
  5. In the metrics you see response times per shift and each waiter's end-of-shift summary with their tables, so you can tell whether service actually got faster.

The ways to call a waiter, with the pros and cons of each

What has to happen when a table calls

Whatever you choose, calling only works if these four things happen.

  1. The alert identifies the table, so nobody has to guess where it came from.
  2. Someone on the team sees it somewhere they look anyway: their phone, a tablet or a screen. An alert that beeps in the kitchen doesn't help whoever is out on the patio.
  3. It shows how long the table has been waiting, so the table that has waited longest is served first, not the one that happens to be closest.
  4. The guest knows the call went through. If they tap and see nothing, they tap again or raise a hand, and nothing was gained.

Without changing your system

Sirvo works alongside the point of sale you already use from day one, without changing it. If you need the two connected, we look at it with you depending on which one you have. Setup takes an afternoon: no data to migrate, no stopping service and no per-user fees. You can start with just calling the waiter and asking for the bill, and add the rest later if it suits you.

What else comes in the same plan

When it fits, and when it doesn't

It fits when each waiter covers several tables, when the restaurant has a patio, several floors or corners that can't be seen from the bar, and when guests wait at peak hours to order or to pay.

It adds less in a small place where the team sees every table from where they stand, or where close, personal attention is what guests come for. It is not for counter service (order at the register and take your food), it doesn't do inventory or recipes, and it doesn't work without internet. It doesn't replace an attentive team either: if nobody looks at the alert, no app will help.

Which call waiter app to choose if you don't want to buy hardware

If you don't want to buy table buttons, the best option is a QR code on each table that lets guests call from their own phone, with the alert reaching your team on the phones or tablets they already carry. What separates one app from another is what happens after the alert.

Sirvo does all three, and that is why we recommend it, knowing it is the maker saying so. If your restaurant has only a few tables and the waiter can see all of them, you may not need any system at all.
