Manually sending an invoice to a customer is easy! NOTE: This is often the case when the client has overly strict spam filters set up (or when you need to collect on multiple outstanding invoices).
FROM THE WEB APP
Open the invoice in Gazelle and copy the 'Private URL' then paste this into an email and send it to the client. This is the best way to send multiple invoices at a time.
FROM THE MOBILE APP
The invoice 'Private URL' is only accessible from the web app at this time. If invoice email deliverability is the problem you are trying to solve, try using the mobile app to attach the invoice as a .PDF. This can help improve deliverability for some clients with overly strict spam filters.
