Food business glossary for makers and farms

Plain definitions of the pricing, production, labeling, shipping and selling terms small food makers and farms run into, from COGS and keystone to lot codes, HACCP and dry ice.

Updated November 2026 by the Madeline's team, who set these tools up for makers and farms.

Start with these four

The terms that matter most early: COGS (what one unit costs you), gross margin (the share of the price you keep), keystone (stores double your wholesale price) and lot code (how you trace a batch). The rest you can look up as they come up.

Terms A to Z

  1. Acidified food

    A low-acid food with acid added so its finished pH is 4.6 or below, like many pickles, salsas and hot sauces. FDA has specific rules for these, including a scheduled process.

  2. Allergen labeling

    US labels must declare the nine major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame.

  3. Average order value (AOV)

    Total sales divided by number of orders. Raising it is often the cheapest way to make shipping costs work.

  4. Batch

    One production run of a recipe. Tracking batches is the base of lot codes, costing and recalls.

  5. Best by date

    A quality date set by the maker, not a safety cutoff for most foods. Set it from testing, not a guess.

  6. Case pack

    How many units come in one wholesale case, often 6 or 12. Stores order by the case.

  7. Co-packer

    A company that makes your product in its facility to your recipe. Useful once demand outgrows your kitchen.

  8. Cold chain

    Keeping a product at a safe temperature from production to the customer, including in the shipping box.

  9. Commissary kitchen

    A licensed commercial kitchen you rent by the hour or month, used by makers who have outgrown cottage food rules.

  10. Consignment

    A store holds your stock and pays you only for what sells. Lower risk for the store, slower cash for you.

  11. Cost of goods sold (COGS)

    Everything it costs to make one unit: ingredients, packaging, labels, labor and a share of overhead.

  12. Cottage food law

    State rules that let people make certain lower-risk foods at home and sell them, usually directly to customers. What is allowed varies by state.

  13. CSA

    Community supported agriculture. Members pay up front for a season of farm shares, usually a weekly box.

  14. Dimensional (DIM) weight

    Carriers charge by the larger of actual weight or a weight based on box size. Bulky cold boxes often bill at DIM weight.

  15. Distributor

    A company that buys from you and sells to many stores. They take a margin, so you sell to them below your wholesale price.

  16. Dry ice

    Frozen carbon dioxide used to keep frozen food frozen in transit. Carriers treat it as a hazardous material: mark the box UN1845 with the weight, and never seal it airtight.

  17. Food safety plan

    A written plan of the hazards in your process and how you control them. Required for many facilities under FSMA.

  18. FSMA

    The Food Safety Modernization Act, the 2011 US law behind most current FDA food safety rules for facilities and farms.

  19. Gel pack

    A reusable pack of frozen gel used to keep refrigerated food cold in a shipping box. Freeze solid before use.

  20. GMP

    Good manufacturing practices. Baseline rules for clean facilities, equipment and handling.

  21. Gross margin

    Profit as a share of the price: (price minus cost) divided by price. A 50% margin means the price is double the cost.

  22. GTIN and UPC

    The barcode numbers retailers use to identify a product. Licensed through GS1 US.

  23. HACCP

    Hazard Analysis and Critical Control Points. A system for finding where food can become unsafe and controlling those points, common for meat, juice and seafood.

  24. Insulated liner

    Foam or fiber insulation that lines a shipping box to slow warming. Paired with gel packs or dry ice.

  25. Keystone pricing

    A retailer doubles the wholesale price to set retail. A $10 wholesale item sells for $20.

  26. Lot code

    A code on each unit that ties it back to a batch, its ingredients and its date. Needed to run a recall and asked for by most stores.

  27. Markup

    Profit as a share of the cost. A 100% markup equals a 50% margin.

  28. Minimum order (MOQ)

    The smallest order a buyer can place, set by the maker or supplier, often a dollar amount or number of cases.

  29. MSRP

    Manufacturer's suggested retail price. The shelf price you recommend to stores.

  30. Net 30

    Payment terms: the buyer pays the invoice within 30 days. Common in wholesale, and a strain on cash flow.

  31. Nutrition Facts panel

    The FDA nutrition label. Some small businesses qualify for an exemption; check FDA rules before you skip it.

  32. pH

    A measure of acidity. Foods at pH 4.6 or below are acid or acidified foods, which changes which safety rules apply.

  33. Point of sale (POS)

    The register and card reader you sell with in person, ideally tied to your inventory and books.

  34. Process authority

    An expert who reviews and sets a safe process for products like acidified or canned foods.

  35. Scheduled process

    The documented steps, times and temperatures that make an acidified or low-acid canned food safe, set by a process authority.

  36. Sell-through

    The share of stock a store sold in a period. Stores reorder from makers whose products sell through.

  37. Shelf life

    How long a product keeps its safety and quality. Set it by testing, especially for anything sold wholesale.

  38. SKU

    Stock keeping unit. Your own code for each product and size, used for inventory.

  39. Slotting fee

    A fee some larger retailers charge to put a new product on the shelf.

  40. Traceability

    Being able to trace a product one step back to its ingredients and one step forward to who bought it.

  41. Wholesale price

    The price you charge stores. Often about twice your cost, so the store can double it at retail.

  42. Yield

    How many sellable units a batch actually makes after losses. Cost per unit depends on it.
