1. Do I 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 the 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 the Service ID and you won't have to create and map products in Mews.

Read the guide below to learn the difference between Products and Items.


2. How to post a 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.

This is because we mark some items as Inactive from the 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 an Outlet Bill is 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 a 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 them to the Accounting report. You can use the suggested filter of the Accounting report and view items based on them.

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

You will see it in the Mews Accounting report reference number of 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. One of the reasons you don't have an accounting category in Mews is that it wasn't sent from the integration partner.

For this we recommend checking the mapping in POS extranet, or contacting your POS integration partner for help.

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

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

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


8. Can I send items from Mews to POS?

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

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

If you have questions about the two systems working together, you can get more information in the guide 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 the 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.

10. Is it possible to cancel Outlet revenue in Mews?

It's not possible to cancel or modify Outlet revenue in Mews. If you'd like to make changes to outlet revenue, it's necessary to send new items with negative "—" value to Mews, so they balance out existing revenue.

Please, contact your POS partner to double check how is it's possible to send cancellations to the Outlet revenue in Mews
