Tech Pack Bill of Materials (BOM)
The bill of materials lists everything the factory buys to make one piece: the fabrics, the lining, the buttons, the thread, the labels, the packaging. One line per material, with a picture, its category, the material itself, where it goes on the garment, the supplier and its reference, the quantity for one garment, the price, the colourway and notes for the factory.

How it works
One line per material
Add a row for every fabric, lining, interlining, button, zip, thread, label and hang tag. Each row starts with a picture of the material, its category, the material itself and its placement on the garment.
Supplier, reference, quantity, price
Then the supplier and its reference, the quantity for one garment in the supplier's unit, metres for fabric, pieces for buttons, and the price. The draft made from photos leaves this part to you; Import and pre-fill with AI reads it from your supplier documents.
Colourway and notes
The colourway says which material goes with which colour of the style; notes carry what the factory must know, a weight, a finish, a care instruction, a substitute if the reference runs out.
Import and pre-fill with AI
The BOM can fill itself from the documents you already have. Press Import and pre-fill with AI, then add up to six files: a supplier quote, a fabric spec sheet, a trims list, a PDF from the mill, or plain photos of a care label, a button card or a zip tag. Read the documents costs 2 credits, and the AI pulls out every component it finds: the material, its placement, the supplier and the reference when the document gives them, the quantity and the price.
Nothing joins the table without you. The lines found are shown first, on the same card, so you can check them before adding; the ones that are already in your BOM are flagged rather than added twice.
| Document you upload | What the AI reads from it |
|---|---|
| Supplier quote (PDF) | materials, references, unit prices, quantities |
| Fabric spec sheet | composition, weight, width, supplier reference |
| Trims list | buttons, zips, labels, threads, with their references |
| Photo of a label or a button card | material, size, reference printed on it |
Why the BOM decides the price
A sample is quoted from this table. Missing lines come back as questions, or as substitutions you did not choose. A complete BOM, with quantities and references, is what lets a factory price the piece and order the right material before the sample is cut. The AI review flags the materials without a reference.

Frequently asked questions
Does the AI draft fill the bill of materials?+
The draft made from photos creates the table and names the visible materials, but it does not know your supplier, your reference or your price. Import and pre-fill with AI does: give it your supplier quotes, spec sheets or photos of labels, and it adds the components with the references and prices those documents carry, for 2 credits per reading.
Which documents can the BOM import read?+
PDFs and pictures, up to six per reading: supplier quotes, fabric spec sheets, trims lists, photos of care labels, button cards or zip tags. You see every line it found before it joins the table.
What unit should quantities use?+
The unit the supplier sells in: metres or yards for fabric, pieces for buttons and zips, metres for tape and thread. Write it in the notes when it could be read two ways.
Can I attach a picture of the fabric?+
Yes. Each line carries a picture: a swatch photo, a creation from the studio, or the image of the trim. Image to fabric can turn a design into a printable textile pattern if the material is a print of yours.
Is the BOM printed in the PDF?+
Yes, as a table in the exported document, with the pictures, so the factory sees the material beside its reference.
