How to manage product data changes without errors in production and sales

5 min read · September 2026

The problem

A change in email — sales and the workshop on different versions

Fashion brand paina product data change breaks production or sales

A change to fibre composition, fabric, a button, the size chart, cost or price often lands in one file or one email and never reaches everyone. Sales, production, the warehouse and suppliers then work from different versions of the same style. The result is a wrong label, wrong sewing, a wrong B2B price or material ordered against an old recipe.

  • the same change in several files and channels
  • workshop and shop on an outdated version
  • errors in the label, BOM, price or measurements
Industry context

Product data is in many files at once

BOM (Bill of Materials)the recipe of materials and trims used per style.

Tech pack / Production Cardthe set of data the workshop needs: construction, measurements, materials, instructions, documents.

In a small brand, measurements are in a spreadsheet, the sketch in a PDF, the colourway in Docs, approval in email. A filename like "FINAL_v3" does not guarantee the workshop replaces the old version. The closer the brand gets to production and labels, the more expensive it is to work from outdated data.

How Go4 solves it

One product card and a release of the version to the workshop

We solve scattered versions with one product card, so sales and production read the same current data.

  • the product card holds BOM, measurements, construction, workshop instructions, costs and documents, among other fields
  • the Release panel on the product card shows gaps in construction, measurements, BOM and costs, samples and files; releasing saves a version of the card from that day
  • composition and care labels take data from the BOM / materials; the production order shows instructions from the card

A change is entered in one place; it then goes to materials, labels and production from the same card — without a separate "FINAL" in Drive.

Steps

  1. 1On the product card, style data is updated (variants, BOM, measurements, construction, instructions, documents).
  2. 2Once the data is closed, a version is released to the workshop (Release); Factory ready is set by the brand.
  3. 3The order, materials from the BOM and labels use the same card — without separate "FINAL" files.

Example: MERU pants, button and lining composition change.

On your side

  • Enter changes on the product card before you send an order or print labels.
  • Close gaps in the Release panel and set Factory ready before production starts.
  • You approve the wording of instructions and the BOM; Go4 keeps them in one place and passes them on to the order / labels / materials.
