Services with POS
Services are used to group different products offered within the same service you offer to your customers, like the mini-bar, room service, parking, the gift shop or automated wine machines. These allow you to set default service settings, as well as group the products offered.
It will be easier for you to have only one service where you have all the products instead of creating the same product for each of the services.
When you create a Service in Mews, you can define a default Accounting category which will be used for each Order. You can have only one default accounting category configured in Mews for the service, but you can assign different accounting categories for each product within that service, or send specific accounting categories for each item when sending Items via the Mews Open API using the AccountingCategoryId.
What is the difference between Products and Items?
Products can be configured and managed from within Mews, whereas Items are not.
Items are usually used in restaurants, where the dishes are being constantly changed, so it would be much more complicated to have to create new products in Mews every time. Items are more complex to send via the API, as they require more information, but this allows for more flexibility on the POS side.
When you submit an Order (using this endpoint), you must send Products or Items.
Products should be created in Mews, hence a mapping must be made with the POS products.
On the other hand, Items can be freely inputted (they can have any name or any value), and only currency and tax codes are required.
