Integration with Fusesign
We use Fusesign as our e-sign solution and it would be great to have the option to send a document directly into the signing software. We've seen a much higher engagement level with Fusesign than any other e-sign product as it doesn't require another login, it uses SMS/email verification instead.
A direct link would smooth out the workflow from the tax product > signing (and maybe even into client files in FYIDocs).

Hi Matthew, it appears that FuseSign is already an integrated app Partner with Xero. As they've designed and built their integration with Xero themselves they'd it'd be best to approach their support to see if this is something they'd consider extending their integration for.
You can find their support contact details at the bottom of their app store listing.
