How to Organize Your Candle SKUs: Scents, Vessels, and Sizes

If you have a handful of scents poured into a few different vessels and sizes, the short answer is yes: track every sellable variation as its own SKU. But you do not need to test, re-wick, or build a separate recipe for every single combination, and that difference is what keeps this from becoming a full time job. A question we get a lot sounds like this: "I have five scents across a lot of different vessels and sizes. Should I track every variation separately?" Let me walk you through how my husband Chad and I handle it at Garsnett Beacon, because once you separate two ideas in your head, the whole thing gets simple.

A recipe and a SKU are two different things

This is the part that trips most makers up. A recipe is the formula you pour: a specific wax, a wick, and a fragrance load that you dial in and burn test. A SKU is the thing a customer actually picks and pays for: a scent in a specific vessel at a specific size. One recipe can produce many SKUs, and that is the whole trick to staying sane.

Here is what that looks like in practice. When we bring a new vessel into the lineup, we test it once to find the right wick and pour temperature. We confirm it burns clean with a couple of our trickier fragrances, because a heavy oil can change how a wick performs. After that, every scent we pour into that vessel rides on the same tested setup. We are not re-testing all five scents in all three vessels in two sizes. We test the vessels, then we pour the scents into them.

So your testing and production planning happen at the vessel and recipe level, and your selling, pricing, and accounting happen at the SKU level. Keep those two lanes separate and the whole system stops feeling overwhelming.

What counts as a SKU

A SKU is anything a customer can choose and buy on its own. If someone can purchase "Vanilla Bean in the 8 ounce amber jar" and, separately, "Vanilla Bean in the 4 ounce tin," those are two SKUs. Same scent, different product, different cost, different price. They each need their own line in your system.

Run the math and it adds up fast. Five scents, three vessels, two sizes is thirty SKUs. That is not a problem by itself, but it is a reason to be intentional. Every vessel and size you add multiplies across your whole scent list, so I would rather sell five scents in two vessels really well than spread myself thin across thirty half-tracked variations. When you are deciding whether to add a new vessel, remember you are not adding one product, you are adding one times your entire scent lineup.

Build a naming system before you have thirty of them

Give every SKU a clean, consistent name and a short code. We use a simple pattern: scent name plus vessel and size. "Cedar and Sage, 8 oz Amber" reads the same way every time, which matters when you are labeling, counting stock, and pulling orders at 9pm. Add a short SKU code for your point of sale and spreadsheets, something like CS-AMB-8. You will thank yourself at markets when you are ringing people up fast and need to know exactly what sold.

The payoff shows up at reorder time. When you can see that CS-AMB-8 sold out three weekends in a row and the 4 ounce tin barely moved, you know exactly what to pour next. Without SKU level tracking, it all blurs into "candles sold well" and you are guessing.

What to actually track per SKU

You do not need to track everything. Four numbers per SKU carry almost all the value: your cost of goods, your price, your current inventory count, and your units sold. Cost of goods is the one makers skip, and it is the one that bites. The same scent in a bigger vessel uses more wax and more fragrance, so its cost is genuinely different, and if you price every size off a gut feeling you will quietly lose money on the big ones. If you want the full breakdown of how to calculate it, we lay it out in our cost of goods guide.

One quick note on the fragrance side, since it affects cost per SKU: your fragrance oil percentage is always calculated on the total candle weight, not the wax weight alone. A lot of makers get this wrong and either underscent or blow their fragrance budget. If the math makes your head spin, our candle math guide and our free calculators do the heavy lifting.

Group for production, split for selling

When it is time to pour, think in vessels, not SKUs. If you have orders for Vanilla Bean, Cedar and Sage, and Fireside all in the 8 ounce amber, you are doing one vessel setup and swapping fragrances between pours. That is far more efficient than bouncing between vessel sizes all afternoon. Plan your batches around the recipe, then let the finished candles flow back out as individual SKUs when they hit your shelf or your site.

This also helps you decide how much to pour. Your sales data tells you which SKUs move, and that should drive your batch sizes so you are not sitting on dead inventory. We dig into that balance in our guide on how much inventory to make.

Spreadsheet or software

When you are starting out, a spreadsheet is completely fine. One row per SKU, columns for cost, price, stock, and sold. The trouble starts when vessel prices change, a fragrance goes up, or you add sizes, because now every cost of goods number is stale and you are updating thirty cells by hand. That is actually why we built Makers Manager. I co-founded it specifically to keep cost of goods accurate per SKU as supply prices move, so your pricing stays honest without the manual grind. If you want to try it, the code CBP7DAYS gives you 7 days free at checkout. Whatever you use, the principle is the same: one source of truth, updated as your costs change. For the rest of our stack, here are the tools and software we actually use.

A few follow up questions we hear

Do my variations each need a separate barcode or UPC?

For your own shop and markets, no. Your internal SKU code is enough to track and sell. You generally only need real UPC barcodes once a retailer requires them for their system, which comes up with larger wholesale accounts. Until then, keep it simple.

When should I retire a SKU?

Let the numbers tell you. If a variation has barely sold over a full season and it is tying up vessels or fragrance you could use elsewhere, discontinue it or move the leftover stock in a bundle. A tight, well tracked lineup almost always outperforms a sprawling one.

How do I handle seasonal or limited scents?

Treat them as their own SKUs with a tag or note in your system so they are easy to pull when the season ends. That way your core lineup stays clean year round and you can see exactly how the seasonal performed when you decide whether to bring it back.

Start with the two lane idea: test and pour at the vessel level, sell and account at the SKU level. Name everything consistently, track the four numbers that matter, and your "lot of different vessels and sizes" turns from a mess into a dashboard.
