History period

The history period is the window of past sales the forecast looks at. It’s either Auto (Logistified picks the optimal window per variant) or Manual (you pick a fixed range). For beginners, switch to Manual + 90 days combined with the Average model. This removes hidden behavior and lets you sanity-check the suggestions against your gut.

Auto vs. Manual

Auto	Manual
Logistified picks the optimal window per variant.	You pick a fixed range, applied to every variant in the view.
The model gets the data it needs.	The math is fully predictable — you see what’s going into it.
Magic — hidden choice.	Transparent — visible choice.
Best once you trust the system.	Best while you’re learning.

Manual presets

When you switch to Manual, you can pick from these presets or define a custom date range on the calendar:

Preset	What it does
Last 7 days	One-week window. Useful for fast-moving, high-volume variants.
Last 30 days	One-month window. Useful for monthly cycles.
Last 90 days	Three-month window. The recommended beginner default.
Last 6 months	Half-year window.
Last year	365-day window. Useful when seasonality matters.
Max	Everything Logistified has on this variant.
Rolling (Past Year + Lead Time)	Past 365 days of history matched against the supplier’s lead-time window projected forward. The seasonal-planning preset.

Beyond these presets you can also pick a custom start/end on the calendar.

Rolling (Past Year + Lead Time)

The one “smart” preset on the list. Its job is to align what you sold a year ago with the lead-time window you’re about to order for.

Mechanics:

The history window is the past 365 days, ending today.
The forecast horizon is your supplier’s lead time projected forward from today.
As days pass, both windows roll forward together — so the comparison stays current.

Pick this preset when seasonality matters and your supplier lead time is meaningful (weeks or longer). For shorter lead times or non-seasonal variants, a fixed window like Last 90 days is usually clearer.

Rolling vs fixed window

A rolling window slides forward each day. “Last 90 days” always means the 90 days ending today, recomputed daily. The alternative is a fixed date range — start and end pinned to calendar dates, never moving.

Use a rolling window when you want a consistent recency. Use a fixed range when you want to lock the math to a specific period (for example, “compare to Q4 last year”).

Why beginners should pick Average + Manual + 90 days

Two reasons:

No hidden parameters. The Average model is “sum sales ÷ days.” That’s it. Nothing magical adjusts the result behind the scenes.
A meaningful window. 90 days usually covers more than one sales pattern (you’ll see the recency of last month plus the rolling history from the two before), but isn’t so old it includes obsolete trends.

Once the suggestions match your intuition for 80% of variants, switch back to Auto. Auto will do better than your manual picks on most variants — but you’ll trust it because you’ve already tested the simple case.

The recommended starter setup
