Please remove the option to charge the customer card against all items under Unassigned.
This is causing operational problems, because is much easier to charge fully for current and future stays all together by mistake or while in a rush. The only way to prevent wrong charging is to manually move the charges to a New Bill.
This is a technical disadvantage.

Old billings screen was able to prevent this as products for future reservations were kept on the left hand side. There was no option to collect payment against them.

We welcome guest that stay more than a week inside our properties. Preauthorizations get cancelled automatically after 7 days which creates an issue for us, in case of broken furnitures in the property or unpaid bills. For this purpose we should be able to create preauthorizations of more than 7 days.

It will be easier when the (Stripe) Merchant commision will be shown in the bank transaction/ payout. At this moment you need to check the fee in Mews (seperately for each property) when you proces a bank statement in the financial accounting systems.

When a booking is made we would like to link it to the reservation the guest made the payment for. Now if a guest makes more bookings we can not see which bookings are paid yet. we can only see what the total amount is

Option to enter amount that we want to assign as the credit limit for the payment method. And then have the option to report all guests whose current balance is greater than the credit limit assigned to the payment method.

Would be great to receive an automated email from Mews when credit limit has been reached.

Currently, if hotels have to change Bank Accounts for their payouts, they need to go through a lengthy process with Support to get this done. If the option is available in Mews directly, we could do it with one click. Of course only finance or admins should have this permission.

It would be very helpfull to have a option to send a secured payment link to guests or companies, this In order to avoid chargebacks and makes it easier for external companies or persons to pay someones reservation via credit/debit card. This also helps whenever a guest doesnt have the credit card of they room payment with him.
Like this you fraude can be eliminated.

It would be nice to be able to correct a wrong input of payment by just being able to modify or delete it.

Perhaps with a time limit of 24 hours or less.

Would like to have configuration to automatically round up and or down on settlement of a guest bill in multiples of 5, 10, 50 or 100 by payment type.

Visible internal notes/tasks inside guests folio billing. So much wasted space. All that space can be used for notes or tasks. Me, personally, i live in billing and i am always there, if you ask me, its the most used window. So i would really love this idea come true. So that all internal notes or tasks about this reservation can be viewed inside billing. Just an idea which i would personally find very useful. Or at least something where we can leave the notes for our colleagues.

For Amsterdam Properties, the virtual Credit card amounts are for less than the full price since the guest needs to pay the 3 euro tourist tax upon arrival. I wonder if the automatic charging could read the amount imported under credit card information.

For Mews terminal it would be nice to have the customer receipt data for successful payment printed on customer invoice.
This could be useful as we would not have to staple the terminal statement to the bill anymore.

When there is a VCC and guest's credit card on the booking, the accommodation payment that should be charged back to the VCC always seems to be charging the guest's credit card. To be able to assign different credit cards to different payments, or at least just VCC's would avoid a lot of overcharging of guests.

When there's a failed automatic settlement, a task is put into MEWS. I would like different options just than a task, so I could for example also be notified by email. Also, I would like to change the settings for the desk (adjust the deadline and department for example)

I'd like to see the balance on the payment window. Include on "Amount" the default payment amount that could be modify if you're not charging the total amount at one time.

With the possibility of 3D secure payments failing, there is a chance this payment is missed and not followed-up.
It would therefore be convenient to receive a notifcation e-mail of failed 3D secure payments. Alternatively, a task could be set (automated).

People are using the same credit card for different profiles (fraudulent bookings). We want to blacklist a credit card.

When a guest enters new credit card details (for example because we couldn't charge their credit card and asked them to provide another one), it would be helpful if MEWS gave us a notification. We now manually have to check if new details were entered.

Please develop auto-fill totals for creating pre-authorizations. Right now, if a guest was to extend or modify their reservation in any way, Mews requires you to literally use a calculator to add up the current authorization(s) and subtract it from what is the new total. This get's really messy when these changes happen multiple times. Having that amount needed field auto-filled would be more accurate, and time effective.
