CelstixRestaurant POS software compared: Celstix, Petpooja, Biller.app and SlickPOS
We make Celstix, so read this with that in mind. Other tools' facts come only from their own websites, read on 6 November 2026. Prices change, so confirm them with each vendor.
Short answer: choose Celstix if you want free QR ordering, kitchen tickets and billing and can live without inventory or delivery-app links. Choose Petpooja or SlickPOS if Swiggy, Zomato and inventory matter most. Biller.app is worth comparing if you want inventory at a low price.

Looking for a Petpooja alternative?
If cost is your reason, Celstix or Biller.app may be enough for a small dine-in restaurant. If you rely on inventory and delivery-app reconciliation, a free tool may not replace it, so test that first.
