1. Do you need to map my products?

It's possible, but not required to map products with POS integration.

Product mapping can be used when you have fixed products in the menu of restaurant.

In case dishes at the restaurant are constantly changing, it's more convenient to add them as custom items. For that you'll only need Service ID and you won't have to create and map products in Mews.

See below what the difference between Products and Items is.


2. How to post complimentary item (Item with price 0) to Mews?

If you send an item with price 0 to Mews, it won't be displayed on the customer billing or in the Accounting report.

The reason for that is we are marking some items as Inactive from accounting point of view. These items are:

  • Items of optional reservations. Until the reservation is confirmed, all its accounting items are inactive.
  • Zero value items.

At this moment it's complicated to build a solution which will treat 0 value items as Active, so we don't have this feature in our system yet.

3. Can I correct a closed bill that was sent from POS to Mews?

After Outlet Bill was sent to Mews, it is not possible to reopen and correct it from Mews.

If you need to make a correction to the bill, you'll need to create a new bill with items/products with negative value and send it to Mews as a new Bill.

For example:

You had a Bill in your POS for

  • 1 beer
  • 2 cokes

You need to remove 1 coke from the bill, so you'll create a new bill in POS and send it to Mews as:

  • - 1 coke

4. Can I review Outlet bills in Mews?

It's not possible to review Outlet bills sent from POS in Mews.

We receive Outlet bills in Logs and add it to Accounting report. You can use suggested filter of the Accounting report and view items based on them.

It's possible to attach POS Bill number to the accounting item of the OutletBill.

You will see it in the Mews Accounting report reference number to the POS Bill.


5. Why Items/Products from POS are received without an Accounting category and it says "NONE"?

Integration partner has sent Accounting category as "null".

As integration partners consume Mews API, they are pushing items to Mews and fetching items from Mews. On of the reasons you don't have accounting category in Mews is that it wasn't sent from the integration partner.

For this we recommend to check the mapping in POS extranet or contact POS integration partner for help.

6. Why Items/Products in Mews have a different accounting category than in POS?

The Accounting category in Mews is not correct? Since the code is being sent to Mews by POS, you will need to contact your POS support and ask them to check the mapping of Accounting categories in POS extranet.


In case mapping seems to be ok, request the logs from integration partner support and contact Mews via [email protected] for further investigation.


7. Why Items/Products in Mews have incorrect VAT/TAX?

Why Mews has assigned incorrect VAT/TAX to an item? How can I fix it?

Mews uses hard coded TaxCodes in order to assign VAT/TAX % to an item.

If integration partner didn't send correct tax code with an Item, it will result with incorrect VAT/TAX % in Mews. Make sure to have the correct tax rate in POS.

List of TaxCodes can be requested by integration partner from Mews with an API call to taxenvironments/getAll endpoint.


8. Can I send items from Mews to POS?

As Integration partner is a consumer of Mews API, it's not possible to send items from Mews to Integration partner.

Integration partner can push or fetch information from Mews, but Mews can't be an initiator.

If you have questions about the 2 systems working together, you can get more information below.


9. Why do I have duplicated items in Mews?


There is only one product ordered in POS and in Mews I can see two of them. If I do the reconciliation, I can see that in Mews it's duplicated.

One of the reasons you may have discrepancy between Mews Accounting report and the revenue report in your POS is because some of the items/bills were sent twice.

In this case, contact the integration partner and request logs from their side in order to confirm if an item was duplicated.
