This episode is a practical walk-through of forecasting for e-commerce growth, specifically how media buyers and operators should think about revenue targets, paid spend, CAC/ROAS degradation, contribution margin, fixed costs, and cash flow without building a fantasy plan that assumes everything stays perfectly flat.

Abir (outsourced CMO/operator for multiple e-comm brands) and owner of UpCounting.com breaks down a simple-but-real framework: start with the story in the historical data to build a forecast that's honest about constraints (marketing efficiency, supply/inventory, staffing, cash conversion cycle). Then, turn the forecast into an ongoing operating rhythm where you review monthly performance vs plan, diagnose why you landed where you did, and update assumptions instead of "hoping next month works."

A big theme: most brands hit a "terminal velocity" with their current offer/creative/channel mix. From there you either (1) increase the value you get from customers (LTV/retention, bundles, new products, adjacent audiences) or (2) improve business efficiency so you can reinvest profit to raise your ad spend ceiling—aka the "two machines" model: ads machine + ops/profit machine. Key Takeaways:

• Using more than just "vibes" to justify perfomance when CAC stays flat while spend goes up.

• How to forecast using your actual "terminal velocity" instead of your dream scenario.

• The difference of forecasting from a revenue goal → spend/CAC → contribution margin, Vs. just backfilling numbers to match a target.

• Knowing where your business actually breaks first (marketing efficiency, inventory, cash conversion cycle, headcount, or fixed costs)?

• The fastest way to spot whether growth is coming from new customers vs returning customers and why this changes the whole model.

• How to properly plan for CAC degradation when you begin to SCALE.

• Why tracking this one metric can confirm if extra spend is actively hurting your brand.

• Moving away from just looking at ROAS and moving on to a monthly system for forecast vs actual + "why did this happen?"

• How to know you're investing cash in the right lever and helping raise your ceiling faster.

• How to run the numbers to insure you're holding your internal team to an ROI standard and not just giving the team a free pass.

• OpEx bloat (tools, subscriptions, extra layers of people) and how it is quietly eating your ability to reinvest in growth.
