Client Billing Question (combining all tool costs automatically)
When setting up a Voice receptionist system for someone using Retell and n8n, there are a number of hard costs incurred by the agency to provide the service, which seems to be typically billed on a monthly retainer, plus cost of AI and calls per minute. These break down into the following platforms and per-minute usage: Twilio Cost per minute & phone number per month Retell Cost per minute AI LLM Cost per minute (within n8n agents) n8n platform cost per month, plus execution credits used that exceed the monthly included credits. [Are there any others I'm not thinking of here?] My question is - Do you have an automated way to calculate and combine all of these numbers easily in a report/invoice every month, or do you go through each platform manually to collate and generate an invoice at the end of the billing cycle? Thanks in advance!
