See Real Forecasts in Action
No setup, no spreadsheets, and no effort.
TSF Lite runs every forecast for you. Each month on the 1st of the month, you receive new 30-day forecasts for every SKU in your catalog. If you choose the Quarterly Upgrade, you'll also receive new 90-day forecasts on the first day of each calendar quarter.
Both versions deliver the same level of precision:
- Gold Line: your best daily forecast for the specific date.
- Green Zone: your safe range 85% and 95% confidence intervals.
See how it works
How It Works (Without the Math)
Traditional forecasting tools generate forecasts sequentially — each new forecast value depends on the previous one. That means their predictions resolve into a mean-value trend that can’t capture or model changes within the forecast period. When demand shifts mid-month, those models keep projecting the same curve, lagging behind real-world movement.
For each date, TSF Lite evaluates up to 800 forecast models (10 seasonal models x 2 series x 40 forecasts each) and selects the one with the best historical accuracy for that day. This independence allows the forecast to adjust immediately when real conditions change, without being chained to yesterday’s trend.
The gold line isn't a trend or a mean value: it's the best answer for that day.
Up to 800 candidate forecasts per date, chosen objectively.
Daily adaptability — forecasts respond to mid-period changes.
Get new SKU-level forecasts every month without lifting a finger.

Why demand planning is the difference between guessing and growing.
Even small forecasting errors add up — overstock ties up your cash, understock costs you sales, and
both make promotions unpredictable. TSF Lite keeps you inside your safe range, so you can plan reorders,
marketing, and cash flow with confidence.
It's not about more data — it's about knowing when to act.
Learn how to use demand planning to drive ROI
Run your business with foresight, not forecasts.
Because knowing the month ahead is better than reacting to it.
Traditional forecasts chase accuracy. TSF forecasts create clarity. Each month starts with a complete picture of what's likely ahead — a daily green zone that defines what "normal" looks like. You don't analyze it. You use it — to plan, to spend, to staff, to stay ahead.
No meetings. No data scientist. Just clarity.
Every TSF forecast is 100% objective. For each date, TSF Lite evaluates up to 800 different forecast models, compares their historical accuracy, and selects the one with the best proven performance — no subjective tuning or backfitting. The result is a forecast grounded entirely in what has worked most accuractly across your own data.

Fewer Stockouts. Less Overstock. No Guessing.
Start each month with clarity.
The green zone defines your safe operating range for each day — your best- and worst-case expectations based on real data.
Watch volatility, not just direction.
When the band widens, expect more variability — it's your signal to build flexibility into cash flow or supply.
Plan inventory, ads, and staffing within the band.
The top of the band is the strong demand scenario. The bottom of the band is the conservative scenario. Plan your orders and budgets around the range that fits your risk tolerance.
Measure signal vs. noise.
If actual results stay inside the band, you're fine. If they consistently move above or below it, something has genuinely changed — that's a planning insight for next month, not a daily fire drill.

The First Forecasts Built on a Scientific Breakthrough
Traditional forecasting models operate on a single timeline — each day’s value depends on the one before it. That means when reality shifts mid-month, their forecasts can’t keep up; the curve is already locked into yesterday’s assumptions.
The Model of Temporal Inertia (MTI) changes this. TSF forecasts operate on two timelines at once — a sequential timeline for short-term continuity and a seasonal timeline that maps recurring patterns across years. This structure lets each daily forecast value stand independently, so the model can recognize and capture changes within the forecast period instead of missing them.
That independence is what makes TSF capable of producing 30-, 60-, and 90-day forecasts with measured confidence and within-period adaptability — something traditional forecasting simply can’t do.
