I assume that many businesses that use TakeApp have multiple sales channels like dine in, delivery apps, TakeApp and others, making setting a specific inventory on TakeApp a bit inaccurate. Therefore, as I've seen in many platforms (in Perú we have Rappi, PedidosYa, Justo) that instead of putting an inventory number, they just put a toggle on and off button for each product. So when a product is out of stock, you just turn it off with a simple click. Additionally, when turning off a product, a pop-up window shows up giving you different options like "Turn off for the day", "Turn off indefinitely" or "Turn off until certain date".
