Sellers price the product, add shipping, and treat packaging as a rounding error. Then margins mysteriously do not match the spreadsheet. Packaging is rarely trivial once you count everything that goes into the box.
Build the list before you build the number
A single shipped order can include a mailer, a treat bag, a label, tissue, tape, a card, and a sticker to close the tissue. Every one of those is a line item. Once you list them from catalogs like https://outus.net/ at their actual per-unit prices, the total is usually two to four times what people guess.
Divide by units, not by orders
If one order contains three cookies in three bags, your bag cost is tripled for that sale. Cost per unit and cost per order are different numbers, and mixing them is the most common error in small business math.
Count the pack that gets ruined
Some percentage of bags get creased, mislabeled, or sealed badly. If one bag in twenty is scrapped, your real bag cost is five percent higher than the invoice. Track the scrap rate for one month rather than assuming it is zero.
Bulk pricing is real, but so is storage
Buying seven hundred bags instead of a hundred lowers the unit price meaningfully. It also puts a large box somewhere in your home for a year, exposed to humidity, odors, and the risk that you change your product. Storage is a cost even when it is invisible.
The line items people forget
- Tape, which is consumed at a surprising rate on every box.
- Printer ink and label sheets for shipping and date labels.
- The mailer or box itself, priced by size rather than by count.
- Fuel and time for the trip to ship, which is real even if unbilled.
- Replacement packaging for orders damaged in transit.
Time is the biggest hidden input
If assembling one order takes four minutes and you value your time at anything at all, the labor cost of packaging usually exceeds the materials cost. Anything that removes a step, such as a bag that seals with a fold instead of a machine, pays for itself twice.
Set a target percentage
Many small sellers aim for packaging under five to ten percent of item price, depending on whether presentation is part of what they sell. Whatever your number, decide it deliberately instead of discovering it at tax time.
Charge for it visibly or invisibly, but charge
Either build packaging into the item price or into the shipping charge. Absorbing it as a gift to the customer is the most common way small operations lose money while feeling generous.
Recalculate every season
Paper prices move, sizes change, and your product mix drifts. A spreadsheet from two years ago describes a business you no longer run.
