Draft invoice will not approve


Help - I cannot approve a draft invoice. My home currency is £ sterling, but I am invoicing in € Euros. Everything is good right up to when I try to approve invoice.
I'm getting this message everytime I try to approve it.

Oops! There was an issue with approving your draft. Please try again.

I know this has been an issue for others - how do I solve it?

Regards and Happy New Year

    Its a CORS policy issue.

    Chrome console shows this error:
    Access to XMLHttpRequest at 'https://api.waveapps.com/businesses/9814822e-c12c-4d48-80a4-c3e7f1dd675a/invoices/839233439625384068/' from origin 'https://next.waveapps.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.


    I have absolutely no idea what this means. Is there a workaround for this please as we sometimes have to bill in euros for French customers.

    Browser Troubleshooting

    A lot of the time, this can be fixed by tweaking some things in your internet browser. Wave supports the latest versions of Chrome, Firefox, and Edge. We'd also recommend that you try using Wave with browser extensions disabled. If you have Chrome, try opening up an incognito window, logging into your Wave account, and try again (or if you have Firefox, open a private browsing window).

    If that doesn't work, you may also need to clear your cache and cookies. You can read more about the browsers we support, and how to troubleshoot issues for your individual browser HERE. If you are still having problems or if you have any other questions, please get in touch.

    Network Troubleshooting

    1. If you're using a VPN, please disable it.

    2. Please power-cycle your modem and/or router. A great article that walks you through how to do this, and why it helps is available here: https://www.lifewire.com/how-to-properly-restart-a-router-modem-2624570.

    3. Try connecting to a different network. The fastest way to do this is usually to tether to your mobile device.

    4. If you're still having trouble, please make sure that your browser is compatible with Wave.

    5. Disabling your antivirus software, or adding waveapps.com to your antivirus whitelist should resolve any access issues you're having with our integrations or third party modals (such as banking login info).


    Done all this and I still can't change the date, I've done dummy invoices galore too, with no result. I want our invoicing to reflect it's 2020. Our fiscal year is the UK fiscal year - is that the problem? Other than that I am going to have to edit every single invoice manually which is a real pain.

    Hi all,

    Unfortunately, I have the same issue!
    I've try the steps described above from @BarsinA but still the issue is not solved.

    Can we please get some assistance on this?


    Still tearing my hair out so tried on a Samsung tab as it has a different OS.... same result. It's not the hardware. Also cannot change invoice numbering despite following all recommendations.

    Hey @Kamirlopez and @STABBOTTS, can you please try creating another draft invoice with the same information and seeing if that will approve correctly? Sometimes particular invoicing information can cause hangups, which sounds like something you might be experiencing. Let's try both creating a new invoice from scratch, and also try duplicating that draft invoice to see if that sorts us out!
