Google Drive backup

Save every issued document to your Google Drive.

In Settings → Integrations, click Connect Google Drive. Sign in with Google in the new tab, then come back. InvoiceHop creates an "InvoiceHop invoices" folder in your Drive.

Turn on Save new documents to Google Drive automatically to save each invoice and credit note as soon as it's issued.
Save documents issued before you connected with the backfill button, or from the Invoices page in bulk.
InvoiceHop only sees the files it creates, never the rest of your Drive.
