Ad Pros: AI-Powered Ad Spend Invoicing Automation
Ad Pros is a training and education provider helping high-growth companies master media buying at scale, with proven strategies and a supportive community.
The Challenge
Ad Pros needed to calculate and issue client invoices based on ad spend data, applying different management fee formulas per client and adding creative service fees where applicable. That calculation and the invoice generation that followed had previously required manual math and manual entry into a billing system.
As the client roster grew, so did the number of formulas and fee variations to track correctly every billing cycle, increasing the risk of a manual calculation error making it into an actual invoice.
The Solution
The Web Hunters built an n8n workflow calculating and issuing client invoices from ad spend data with no manual math. The workflow pulls ad spend, client details, and invoice formulas from a master Google Sheet. An AI step analyzes the spend and applies the formula to calculate the management fee.
A second sheet check determines if the client receives creative services and adds that fee. The total is written back, an invoice is generated through the billing API, and the invoice ID is recorded. Ad Pros checks a box in the sheet and the invoice sends automatically via email template.
Results and Outcomes
Replaced manual invoice calculation and generation with an end-to-end automated billing process.
