What we need in the file

Don't reformat anything. Export what your system already produces. Our parser reads the common column names automatically, so "Ship Date," "Date Shipped," and "Shipment Date" all land in the same place.

The seven that matter most. The more of these your file carries, the sharper the analysis:

• Ship date, so we can see volume by month and find your peak.
• Weight. A bare number is read as pounds; "12 oz" or "1 lb 4 oz" also work.
• Destination ZIP (or a zone column, or a full ship-to address). This is what drives the zone math.
• Carrier: USPS, UPS, FedEx, DHL, OnTrac, UniUni, Amazon, and the rest.
• Service level: Ground, Priority, SurePost, mail class, whatever you call it.
• What you paid: rate, postage, shipping cost, or freight charge.
• Order or tracking number, so multi-item orders collapse to one parcel instead of counting twice.

Helpful if you have them: package dimensions as a single L x W x H column, ship-from location, destination state and country, quantity, order total, and package or pallet counts.

Your file is used only to prepare your analysis. We don't share it, sell it, or add you to a drip campaign. It's stored in a private, access-controlled location, deleted within 90 days, and removed sooner if you ask. Most exports describe parcels, not people; if yours includes recipient names or addresses, you're welcome to drop those columns first. The analysis doesn't need them.
