About ReportStack

Mission

ReportStack exists because GoHighLevel agencies that run more than a handful of sub-accounts hit a wall: every login surfaces one client at a time, and there is no native way to see how the entire book of business is performing in a single view. Pulling that picture together by hand each Monday morning eats hours and goes stale by Tuesday.

The product is two parts: a cross-sub-account dashboard that rolls up sales, leads, ad spend, and ROAS across every location an agency owns, and a scheduled white-label PDF reporter that delivers a branded weekly or monthly summary to each client's inbox without anyone clicking a button. Same data, two surfaces — operator inside, client outside.

Founder

ReportStack is built by Avinash Sangle, an operator-engineer who has spent the last decade shipping AI, MCP, and DevOps systems for B2B software teams and hit the cross-sub-account reporting gap firsthand while supporting agencies on GoHighLevel. ReportStack is currently a one-person studio; every line of code, every customer email, and every roadmap call is owned end-to-end.

Third-party transparency

ReportStack relies on a small set of vetted processors to operate. The full privacy treatment lives on /privacy; this is the short version.
