Don't get fooled

5 mistakes operators make when choosing

Mistake #1 — Forecasting each channel separately

Per-channel forecasts in three spreadsheets never reconcile.

Fix: Pick a tool that rolls Shopify, Amazon, and wholesale into one model.

Mistake #2 — Forecasting revenue without inventory cover

A revenue forecast you can't fulfill is a fiction.

Fix: Tie units-on-hand to forecast revenue.

Mistake #3 — Ignoring open wholesale POs

Wholesale POs land 60–90 days ahead.

Fix: Ingest open POs into the forecast.

Mistake #4 — Buying an enterprise FP&A tool at $5M GMV

NetSuite Planning and Anaplan land at $30K+/yr.

Fix: Pick a per-account ecom-native tool under $400/mo.

Mistake #5 — Trusting a single-channel tool with a multi-channel brand

Triple Whale is great for Shopify-only.

Fix: Match tool channel coverage to revenue mix.

How much should an ecom brand spend on sales-forecast software?+

Median $10M GMV brand spends $4,200/year.

Do I need an FP&A hire before buying a forecast tool?+
