Automate Invoicing Process with Go High Level

I need to automate our invoicing process using Go High Level based on opportunity lead value to streamline operations. The scope of work includes automating invoicing processes to enhance efficiency and reduce manual errors. The ideal candidate should have experience with Go High Level and a strong understanding of automation workflows. Scope of work - Automate invoicing process using Go High Level - Dynamic invoice amount based on opportunity lead value - Configure Workflows (GHL, Make, Stripe, QB) with whats needed We have 3 points of invoicing a customer: 1. Initial deposit to customer once opportunity is changed to new stage 2. Once an appointment date is booked on GHL Calendar it should charge half of the remaining balance (amount - 500 / 2) on the appointment date. 3. Final invoice of remaining balance once opportunity is moved to final stage. (If payment schedule can be automated for the remaining balances then we can use custom fields) Also must include Cash/ACH vs Cash/Check so that the customer can choose to bypass the processing fees. All 8 invoice templates are already created in GHL (deposit w/fee, deposit no fee, first installment w/ fee, first installment no fee, final installment w/fee, final installment no fee, Paid in Full w/ fee, Paid in Full no fee). All custom fields are also created already. We want to make sure that once the Deposit is paid, any further payment (whether PIF or Installments) can be auto-charged with card/ach on file assuming the original deposit was paid with ACH/Card. As long as we invoice with ghl then it will sync with QuickBooks, but if we use stripe api or something else then we need to make sure it syncs with GHL.
