One bad CSV can delete your variants, mangle your prices, or get your products rejected by Google. Preflights inspects your supplier file first and tells you exactly what's safe to import, what to review, and what to fix.

Read-only·we never touch your store·24-hour turnaround

Why a check first

Import tools move your data. Preflights checks it first.

Bulk importers and feed apps do exactly what you tell them — including pushing a broken file straight into your live store. Preflights is the pre-flight layer that runs before them, so the file you import is one you've already cleared.

Before the import, not after

See variant, price, image and GTIN problems while they're still in a file — not after they've overwritten your store or stalled in Merchant Center.

Deterministic, not guesswork

Rule-based checks against Shopify import behavior and Google's product-data requirements. Every flag has a concrete cause and a concrete fix.

Read-only by design

You send files; we send a report. Preflights never connects to or writes to your store, so there's nothing to break and nothing to trust us with.

What Preflights catches

Nine checks, each tied to a real Shopify-import or Google-rejection consequence. A flag means a rule was broken — not a probability.
