Currently there is no way to map or customise the data sent from GHL to Quickbooks.
In addition to this there needs to be several this updated:
  1. The ability to map invoice numbers (to match GHL and Quickbooks)
  2. You should be able to add prefixes to the invoice number eg. in GHL "inv_00003" in GBO "ghl_00003"
  3. Map company name as display name.
