Integrations for Self Ordering

[CafefamiliarAmaru]

Hello everybody! I have been checking out the integrations for QR menus and self-ordering. Otter is too expensive for us, so I did not try it. Menutiger would be great and also affordable, but the problem is, that customers have to click on pay and select a payment method everytime they want to order something. This is confusing and will prevent them from ordering. Customers at a table want to order and pay upon leaving. I am not sure if Loyverse can handle open orders from other solutions, the support from Orderinla told me that Loyverse does not support open receipts. I also tried Instalacarte but they do not provide this feature.Additionally the free version of Instalacarte did not work at all when trying to access the customer men because of server problems (due to their support).  I did not try Feedus because they do not show any pricing information, and it seems they do not support QR self ordering.  I also tried MyMenu but first of all it is a little expensive for us and second they do not offer the local currency. Then they do not reply to any questions in their support Whatsapp chat. So I will not use it, because of bad support. 
As our café is in Bolivia with meals between 1 to 3 USD, unfortunately we cannot afford expensive solutions like Otter... 

If you have any experience or recomendations, please let me know. I saw a solution in Loyverse with configuring a user only for clients which seems interesting, but I see a problem, when people have to select their table themselves. This will definitely not work here...
