Specialty food inventory and where to source it
How much specialty food inventory to hold, and where to source ingredients, packaging and finished goods from suppliers who serve small makers.
What to take away
- Specialty food inventory needs three numbers per product, not one: ingredient cover, packaging cover, and finished units. Each is sized by a different clock.
- Ingredients are sized by lead time and by what a stock-out costs. Finished goods are sized by shelf life and what dating out costs. The two logics pull against each other.
- Sourcing splits three ways. Ingredients come from distributors and importers, packaging from converters and stock houses, finished goods from your own batch or a co-packer.
- No figure here is a quantity. The variables are named so you can fill them from your own records.
- Recalculate monthly and after any change in demand, lead time or shelf life.
Ingredients: the reorder point
For each ingredient, define four variables.
Reorder Point Variables
- uusage per week
- Lsupplier lead time in weeks
- vweek-to-week usage swing
- Ssafety stock
Reorder point = (u x L) + S. When stock hits it, you order.
Set S by what a stock-out costs. The ingredient that defines your product stops the line, so S is large. A garnish you can swap gets a small S. One S for everything either ties up cash or halts production.
Ingredients: the shelf-life cap
Every ingredient has a clock. The most you should hold is u times its shelf life in weeks, minus a margin for the time it takes to use the last of it.
Shelf-Life Cap Check
Does reorder math exceed u times shelf life?
supplier problem: closer supplier or smaller orders
hold at reorder point
If the reorder math says hold more than the cap allows, that is a supplier problem. Lead time is too long for how fast the ingredient turns. The fix is a closer supplier or smaller, more frequent orders, not a bigger shelf. The supplier review list covers what to ask before this bites.
Where ingredients come from
Specialty makers buy through six channels, and most use two or three at once.
Ingredient Sourcing Channels
Broadline distributor
- Examples
- Sysco, US Foods
- Best for
- Dry goods, oils, dairy
- Pricing model
- Account pricing, minimums
Specialty/natural distributor
- Examples
- UNFI, KeHE
- Best for
- Natural, organic ingredients
- Pricing model
- Case pricing, slotting
Importer/ethnic wholesaler
- Examples
- Atalanta, Baldor
- Best for
- Olives, spices, cheeses
- Pricing model
- Per-case, freight added
Broker/co-packer desk
- Examples
- Regional brokers
- Best for
- One-off or hard-to-find
- Pricing model
- Commission or cost-plus
| Channel | Examples | Best for | Pricing model |
|---|---|---|---|
| Broadline distributor | Sysco, US Foods, Gordon Food Service | Dry goods, oils, sweeteners, dairy at volume | Account pricing, delivered; minimums per drop |
| Specialty and natural distributor | UNFI, KeHE, The Chefs' Warehouse | Natural, organic and better-for-you ingredients | Case pricing plus slotting on some programs; resale certificate required |
| Importer and ethnic wholesaler | Atalanta, Sahadi Wholesale, Baldor Specialty Foods | Olives, spices, cheeses, single-origin items | Per-case, freight added; some locations allow will-call |
| Bulk spice and herb supplier | Frontier Co-op, Starwest Botanicals, Atlantic Spice Company | Spices, herbs, teas and blends | Wholesale account or business license; case sizes often start at 1 lb |
| Cash-and-carry restaurant supply | Restaurant Depot, Jetro | Small-batch dry goods, frozen items, disposables | Membership with a business license; pay at pickup |
| Ingredient broker or co-packer's buying desk | Regional brokers, your co-packer | One-off or hard-to-find items | Commission or cost-plus |
For a single-origin spice or a specific varietal, a broker earns the fee. For flour and sugar, the broadline truck is cheaper and simpler. Ask each for a spec sheet and a certificate of analysis before you commit, because your allergen and label work depends on what the supplier certifies.
The Specialty Food Association runs Fancy Food Shows in New York and Las Vegas. Exhibitor lists are public and free to browse, which is useful before you open accounts.
Packaging: cover, not clock
Packaging does not expire, so the constraint is cash and space. Per format, define q = units sold per week, Lp = packaging lead time including artwork and printing, and Mp = the supplier's minimum order.
Packaging Order Variables
- qunits sold per week
- Lppackaging lead time
- Mpsupplier minimum order
Hold at least q x Lp plus a margin, and reorder at Mp. The minimum is the real problem. A printed pouch or custom lid is sold in quantities sized for a larger operation, so the first order can be months of supply.
Where packaging comes from
- Stock jars, bottles and closuresBerlin Packaging, SKS Bottle and Packaging, Container and Packaging Supply. No minimums on many items, and no artwork cost.
- Printed pouches and rollstockePac Flexible Packaging, Glenroy, Roastar. These converters run digital short runs, which keeps plate costs off a first order.
- LabelsAvery WePrint, Sticker Mule, Blue Label Packaging. Short runs are cheap; the artwork is the cost.
- Corrugated shippers and retail-ready traysUline for stock sizes, PackagingSupplies.com for small quantities, and a local box plant for custom print.
Buy stock first. Move to custom print only when volume justifies the plate or die charge.
FDA labeling before you print
A label change strands whatever is already printed, so settle the label before the press run. FDA's Questions and Answers Regarding Food Allergens covers the allergen declaration. Confirm your own label with FDA or a qualified food regulatory attorney, not from a supplier's template.
Finished goods: the batch against the clock
This is the calculation that decides the business. Define d = units sold per week per product, T = shelf life in weeks, and m = the life a buyer requires on delivery.
Finished Goods Cap
- dunits sold per week
- Tshelf life in weeks
- mlife buyer requires on delivery
- d x (T - m)maximum units to hold
The most units you should hold is d x (T minus m). Batch size is bounded by that number minus what is on hand. If your equipment makes more, make a smaller batch or sell faster. Do not make the big batch and hope.
Ask buyers what remaining life they require. Retailers commonly specify a fraction of shelf life, and that fraction is m. It is theirs to set and yours to ask.
Where finished goods come from
You have three sources, and the choice is about volume and risk, not preference.
- Your own kitchen or commercial rental. Highest control, lowest minimum, and the only option at the start. See the licensing and compliance guide for what a licensed space requires.
- A co-packer. Runs are quoted per batch with setup, ingredient, packaging and labor lines. Co-packers cluster in Los Angeles, Chicago, Portland and Texas. Ask for a sample run before signing.
- A white-label or private-label maker. Fastest to shelf, least control over formulation, and the product is not exclusively yours unless the contract says so.
For co-packing, PartnerSlate lists contract manufacturers by category and asks for a project brief. The Specialty Food Association's Fancy Food Show connects makers with co-packers and distributors. ThomasNet lists food manufacturers and packagers by region.
A worked example in letters
A product sells d units a week with shelf life T weeks, and buyers want m weeks of life remaining. The finished goods cap is d x (T minus m). Suppose a batch yields U units.
If U exceeds d x (T minus m), then U minus d x (T minus m) units may date out the day the batch is made.
You can cut U, which raises unit cost because fixed batch cost spreads over fewer units, or raise d, a sales problem. Write both numbers down and pick which problem you are solving.
The launch sequence in how to start a specialty food business makes this same call at its fourth stage.
What the arithmetic fails to show
- Seasonality. A d measured in a slow month is wrong in a busy one. Use last year's same-season record where you have it.
- Cold space. The finished goods cap may exceed what your refrigeration holds. Then the equipment is the constraint, and the equipment and setup guide is the next read.
- Lot discipline. Holding the right quantity with no lot number is holding something you cannot trace.
- Cash. The formulas say what to hold. They do not say you can afford it.
The records the arithmetic needs
Batch records for u and U, a receiving log for L, sales by product and week for d and q, and an established shelf life for T. Without those, every variable is a guess.
The same records serve general bookkeeping. The Internal Revenue Service: What kind of records should I keep? guidance leaves the system to you, provided it clearly shows income and expenses with supporting documents. A receiving log with invoices attached is one of those.
Whether you must hold supplier documentation in a written food safety plan depends on your facility's position under the preventive-controls rule. The U.S. Food and Drug Administration: Preventive Controls for Human Food page explains what covered facilities must hold, and coverage depends on the facility. Confirm your status with FDA or a qualified food regulatory attorney.
Recalculating
Every variable moves. Lead times lengthen, a buyer changes m, a product's d doubles after a good demo. Rerun the three calculations monthly and after any of those changes.
The wider framework, with the three stocks and their clocks, is the inventory and sourcing guide. The point where the finished goods cap becomes the ceiling on growth, so more volume needs a longer shelf life or a bigger cold room, is where the expansion and market guide picks up.
Common questions
How many weeks of ingredients should I hold?
Lead time plus safety stock, capped by the ingredient's shelf life, per ingredient. The ingredient that stops production gets more cover; one you can substitute gets less.
What if my supplier's minimum is more than the shelf-life cap?
Then that supplier is wrong for that ingredient at your volume. Find one with a smaller minimum or shorter lead time, or split an order with another maker.
How do I establish shelf life?
By testing, by a process authority where your product class requires one, or by the agency's guidance for your class. Ask FDA or your state which applies. A guessed T makes every finished goods calculation a guess.
Should I make bigger batches to lower unit cost?
Only up to the finished goods cap. Below it, bigger batches lower cost per unit. Above it, units date out and cost per sold unit rises.
