If your customers do not receive the invoices you send with the Send Invoice option in Wave, there are a few troubleshooting steps you can take.
The first step is to have your customers check the filters in their email account, and their junk/spam folders. If this does not resolve the problem, have them add @waveapps.com to their address book before you try sending them another invoice.
An alternative option is to send invoices to your customer using a different method. You can find the instructions to do so for the browser app and the mobile app in Send an invoice.
If you continue to have issues with customers receiving invoice emails, click on the help icon on the bottom right of your screen in your web browser, or head to More > Support on the mobile app. Type “my customer isn't getting invoices” into the chat, and Wave's support chatbot, Mave will assist you.
