Frequently asked questions

Everything about file formats, data, and how to read the results.

What file formats work?

A CSV is all you need. A standard Shopify order export drops straight in, and so does almost any sales spreadsheet exported to CSV — even with messy headers, mixed date formats, or currency symbols. Seasonly auto-maps your columns to dates, products, quantities, and prices. You can optionally add a Shopify products export for category insights.

How much data do I need?

At least 12 months — a full year so every season is represented. Files with less than that are turned away with an explanation. 18+ months is ideal: more history means more reliable seasonal patterns and higher-confidence recommendations.

Are my files stored anywhere?

No. Your file is processed in memory to produce the analysis and is not written to a database or saved to disk. When you close the tab, there's nothing left behind. See the Privacy page for the full detail, including what happens when optional AI features are enabled.

How should I use the recommendations?

As insights to test, not guarantees. Seasonly reads patterns in your own past sales; it can't prove cause and effect, and markets shift. Treat a suggested markup as a hypothesis to try on a few products and measure — not a rule to roll out everywhere at once.

What do the markup and markdown months mean?

For each product, Seasonly calculates a demand index per month, where 1.0 is an average month. Markup months are months that run well above average (index ≥ 1.15) — demand is strong, so it's a sensible place to test a higher price. Markdown months run well below average (index ≤ 0.85) — demand is soft, so a promotion or markdown tends to fit better.

Why is a product marked low confidence?

Confidence reflects how much history and volume back a product up. Products with a full, high-volume history get high confidence; thinner or newer products get medium or low, and for very low-volume items Seasonly points you to the broader category pattern instead.

What does it cost?

The seasonal dashboard — your demand pattern, heatmap, and per-product pricing windows — is free to use. The optional AI-written analysis (a plain-English summary with your top moves and methodology) is a paid add-on. Pricing may change as the product evolves; email us if you'd like current details.
