Ilija Petrovic

I spent four and a half years at a B2B SaaS company that scaled past $20M in ARR, starting in customer support and finishing as Project Manager and Automation Architect. Along the way I owned billing, retention analytics and revenue operations, and became admin and owner of Zapier, Google Workspace, ClickUp and GoHighLevel alongside ChurnZero and Stripe.

What I actually do is connect the systems revenue runs through. I administered Stripe across subscriptions, pricing, disputes and fraud, built the reporting layer in SQL, Power BI, Looker Studio and Apps Script, and designed 150+ automations across Zapier, Make and n8n tying Stripe, ClickUp, Intercom, HubSpot, Salesforce and GoHighLevel together.

Work I am proud of. I built Success AI, a Slack agent on Zapier that absorbed roughly 30 hours a week of admin work and is used daily by Support and Success. I automated customer signup end to end, removing 40+ hours of manual work a week across 200+ signups a month. I lifted the dispute win rate from 28% to 42% by automating the chargeback workflow, and cut about $30,000 a year in software spend by replacing the paid dispute platform and restructuring licensing. Earlier I ran a pricing and discount leakage analysis on raw Stripe data across more than 10,000 subscriptions that changed how leadership used the discount lever, and built a predictive renewal model in Apps Script that merges Stripe billing history with ChurnZero usage into one health profile per account, surfacing 90 day churn risk.

I also lead. I built the escalations function from nothing, set the workflows, prioritization and SLA standards behind it, lifted retention by 20%, and owned hiring, KPI design, scheduling, training and performance development for the team.
