The situation

A Series C VP Finance was rebuilding the revenue forecast manually every single week. Monday morning: export from Salesforce, export from Stripe, export from HubSpot, paste into Excel, reconcile the numbers, apply the forecast model, write the commentary, send to the CEO and CFO by noon. Every week. Without fail. For two years.

She estimated it was taking 8 hours per week. 400 hours per year. On a task that produced the same output every time from the same inputs.

The build

We built a fully automated revenue forecasting system with three live data integrations and an AI commentary layer:

  • Salesforce integration: pulls opportunity pipeline, stage, ACV, close date, rep, and product mix every Sunday night
  • Stripe integration: pulls MRR movements, new subscriptions, upgrades, downgrades, and churn every Sunday night
  • HubSpot integration: pulls marketing qualified leads, conversion rates, and attribution data

The system applies a consistent forecast methodology – weighted pipeline, historical conversion rates by stage and rep, seasonality adjustments – and produces the weekly forecast automatically. At 5:30am Monday, the AI layer generates commentary on the key changes from prior week: what moved in pipeline, what closed, what churned, what the updated ARR projection is.

At 6am Monday, the VP Finance receives a Slack message with the complete forecast and commentary attached as a PDF. She reviews it in 20 minutes. If nothing is wrong, she forwards it to the CEO with one click.

"I used to dread Monday mornings. Now I wake up and the forecast is already in my Slack. It takes me 20 minutes to review something that used to take my entire morning."

What the system produces weekly

  • Current week ARR: actual MRR/ARR, weekly change, versus forecast
  • Pipeline summary: total pipeline by stage, weighted pipeline, coverage ratio
  • Bookings forecast: current month, next month, next quarter – three scenarios
  • Churn and expansion: gross churn, net churn, expansion ARR, NRR rolling 12-month
  • Sales rep performance: bookings by rep versus quota, pipeline health by rep
  • AI commentary: key changes from prior week with CFO-voice narrative

The outcome

The system has run for 9 consecutive months without manual intervention. The VP Finance reclaimed 400 hours per year. The CEO now gets a better forecast, faster, with more context than the manual version ever provided. The company added it as a standard item in their weekly executive meeting.
