For home coffee roasters

The roast shrinks the bag. Price from what's left.

Micro-roasting has one piece of math the spreadsheet always fumbles: green beans lose about 15% of their weight in the roaster, so a 12-oz bag starts life as nearly 14 ounces of green. Get that wrong across a season and the margin quietly evaporates with the chaff. MadeKeeper builds the shrink into every batch, valve bags and labels included.

How MadeKeeper maps to your roaster

Green by the pound, priced by originThe Ethiopian at $6.40 and the Brazil at $4.90 log as separate materials — each roast pulls from its own sack, so single-origin pricing stands on single-origin cost.

Roast loss in the recipeThe batch recipe knows 8.8 pounds of green becomes 7.5 pounds roasted. Your cost per bag is built on beans that survived, not beans that went in.

Valve bags and labels countedOne-way valve bags at 44 cents are the priciest packaging at the farmers market table. Logged per bag, they keep the $16 price honest.

Markets, subscriptions, and the office orderSaturday tables, a monthly coffee subscription, and the standing office-delivery account each track their own channel and their own margin.

One roast session, to the penny

Say you roast for 10 12-oz bags:

8.8 lb green beans @ $5.60/lb (15% roast loss)$49.28
Roaster fuel and power$0.85
10 valve bags @ 44¢$4.40
10 labels @ 10¢$1.00

Session cost — $5.55 a bag$55.53

At $16 a bag you keep $10.45 — and when the green supplier raises the Ethiopian a dollar, the next session's cost says whether $16 holds or the origin rotates out. No more finding out at tax time.

Roasted coffee is on most states' cottage food lists — MadeKeeper keeps the batch, date, and label records that paperwork asks about, in the app instead of a roast log that stops at flavor notes; your state's rules stay yours to check.

Straight about what's live

Materials and true cost per piece, products (in bulk or one-of-a-kind), sales that drain stock, the was-this-fair-worth-it event math, mileage, expenses, and the year-end tax packet — all in the app today. Etsy and Square sync, your own storefront, a booth card reader, and shipping labels are building, shaped with founding makers. Nothing above describes a feature that doesn't exist without saying so.

Questions home coffee roasters ask

Why does the 15% loss matter so much?

Because it compounds silently: price bags from green weight and every bag undercharges by two ounces of beans. Across a thousand bags a year, that's a sack of coffee you gave away. The recipe's loss factor closes the leak permanently.

How do I track multiple origins and blends?

Each green logs as its own material; a blend's recipe pulls from two or three sacks at ratio. Single origins and blends each know their true cost, which is what makes the $2 single-origin premium defensible.

Does the roaster itself go in the math?

As an expense, visible at tax time — with a per-session wear share if you want each bag to carry it. Most micro-roasters add it once volume gets real; the app makes it a one-line change.
