Growth amplifiers
A growth amplifierGrowth amplifierA manual nudge to a forecast — "expect 30% more sales between Black Friday and Christmas." Stacks on top of whatever the model predicts. Use it for campaigns, launches, and known events the model hasn't seen yet.

multiplies the forecast by (1 + boost) over a date range. A 30% boost means “expect 30% more sales than the model would predict, every day inside this range.” Useful when something the model can’t see in history is about to drive demand — campaigns, launches, known events.

What an amplifier does
Section titled “What an amplifier does”The amplifier multiplies the forecast model’s daily prediction by (1 + boost) for each day inside the range. The boost is a percentage; 30% means 1.30x; 100% means 2x.
Because the forecast feeds the reorder math, an amplifier shifts everything downstream: the reorder point gets larger, the reorder date moves earlier, the reorder quantity goes up.
When to use one
Section titled “When to use one”- A scheduled marketing campaign (Black Friday, Cyber Monday).
- A product launch (new collection drop, influencer collaboration).
- A seasonal push the historical data doesn’t reflect — your first ever Christmas in business, or a major one-off promotion.
- A known one-off (a TV mention, a viral moment you can plan around).
Not useful when the forecast model can already see the pattern in history. Recurring seasonality (yearly cycle, weekend uplift) is the model’s job, not yours.
Setting one up
Section titled “Setting one up”Click the Amplifier button in the Forecast toolbar. The popover lists current amplifiers. Click “Add amplifier” — pick:
- Boost percentage (default 15%).
- Start date.
- End date.
Save. The forecast recomputes within a minute.
Status badges
Section titled “Status badges”Each amplifier shows one of three states:
- Active — today is between start and end.
- Upcoming — start is in the future.
- Past — end is behind today.
Past amplifiers stay on the list — they’re history. Delete them when you’ve collected enough data to know whether the campaign worked.
Stacking
Section titled “Stacking”Two amplifiers covering the same day add up. Two +15% amplifiers means +30% for that day. Useful when you want to compose effects (“baseline launch boost” + “extra Black Friday boost”).
What it doesn’t change
Section titled “What it doesn’t change”- Historical data — amplifiers only affect the forward forecast.
- The forecast model itself — Auto still uses your sales history to pick the model. The amplifier rides on top.
- The simulation steps — the day-by-day inventory simulation just runs against the amplified daily-demand vector, so all downstream reorder columns shift accordingly.
Removing one
Section titled “Removing one”Delete from the popover. The forecast recomputes immediately.
