There is another scenario to have this, when customer wants to pay a High Ticket amount like $30K but with multiple credit card then its not possible to take for a single Invoice and we have to take if offline which requires so many manual activities like Affiliate/Sales commission, EMI Payments, Reminders, etc.

Also, We need an automation trigger for "partial payment" so we can calculate the balance due and include that in an email with a custom value.

Agreed, got a dj client who needs to be able to split payments and allow partial payments and tracking. Pay all, pay 50% or custom amount but able to track how much total is due. This way client does not need to create multiple invoices for one big order.

I definitely agree! I've been checking this thread for the past few months now. I work in the construction industry and everyone of my clients needs the ability to collect a 50% deposit from their customers. For now, we are having to use Zapier to communicate with Quickbooks and GHL. I'm super excited for when this feature comes out because its going to make it a no brainer choice over systems like Jobber. Hopefully we will be able to send estimates from the mobile app as well!

Agreed, this would be extremely useful

Additionally, most if not all service based businesses "Mark Up" their services. There needs a way to be able to use mark-up when creating an invoice. This is a major selling feature of Quickbooks.
