Hello, I am a brand new user of Zoho Books with an invoicing question. All my company's projects are billed as fixed cost for project...& every project is invoiced at the completion of each of 4 milestones.  These milestones are always the same & are always billed at the same amount (as % of total project cost...which does vary from project to project).  Is there a best practice for setting these invoices up to save time and/or be consistent?  It would be wonderful if I didn't have to enter these invoices manually & individually for every project.  Thanks so much for any tips on this!
