What goes in Materials

The Materials section holds every raw input you use to make your products. In Sunday Maker, "materials" covers a lot of ground:

• Blanks — finished items you decorate (tumblers, shirts, ornaments, cutting boards)
• Sheet goods — raw materials you cut pieces from (acrylic sheets, wood, vinyl rolls, transfer film)
• Consumables — materials used up in the process (sublimation ink, DTF powder, CerMark spray, weeding tape)
• Packaging — boxes, bags, tissue paper, labels, hang tags
• Fragrance ingredients — wax, fragrance oils, wicks, vessels, additives (when the Fragrance Lab module is enabled)

Unit costs — the most important number

Every material needs a cost per unit — what you pay for one gram, one sheet, one each, one milliliter. This is the number that flows into your products and jobs.

If you buy in bulk, divide what you paid by what you got:

• 25 tumblers for $175 → $7.00 each
• 1 lb of soy wax for $1.50 → $0.0033 per gram (divide $1.50 by 453.6)
• A 12"×24" roll of HTV for $12 → $0.042 per square inch (divide by 288)
• A liter of sublimation ink for $18 → $0.018 per ml

Getting this number right is the foundation of accurate costing. If your cost per unit is wrong, everything downstream is wrong.

Blanks: cut vs purchased

When you add a blank, Sunday Maker asks if it's purchased (you buy it ready to use) or cut from a sheet good (you cut it yourself from a larger material). For cut blanks, it calculates the cost per piece from the sheet cost, dimensions, and how many pieces you get per sheet — accounting for waste.

How materials connect to products and jobs

Once a material is in your library, you can add it to any product recipe or job. Sunday Maker uses the current cost per unit to calculate that material's contribution to the total cost. If a material's price changes, update it in the Materials library and rebuild any affected products or jobs to reflect the new cost.

Note: saved jobs snapshot costs at the time they're saved — updating a material won't change a job you've already saved. This is intentional, so your historical records stay accurate.

Organizing your materials

Use descriptive names that match how you think about your supplies — "20oz Skinny Tumbler (White)" is more useful than "Tumbler" when you have several sizes. You can also add supplier notes and purchase information to each material for reference.
