WTF does that mean?

Business credit is your company's own borrowing history and reputation, separate from your personal credit file.

COGS (cost of goods sold) is what the items you actually sold cost you — not what you spent on inventory during the period.

An EIN (Employer Identification Number) is your business's federal tax ID number, issued by the IRS.

An EIN is a federal tax ID for your business. A resale certificate is a state-level document used when buying qualifying inventory for resale.

Inventory turn is how many times you sell through your average inventory in a period — COGS divided by average inventory value.

Landed cost is what a unit really costs you once it is in your building and ready to sell — purchase price plus freight, handling, parts and the cost of what could not be sold.

Markup is measured against your cost. Margin is measured against your selling price. The same dollar of profit produces a bigger markup number than margin number.

Net 30 means the full invoice is due within 30 days of the invoice date. The supplier gives you the goods now and takes payment later.

A resale certificate is documentation used under applicable state rules when buying qualifying inventory for resale, so the supplier does not collect sales tax on that purchase.

Vendor terms are an agreement that lets you receive inventory now and pay the supplier later, up to an approved limit.
