Fashion PLM software for Shopify brands: styles, techpacks and lifecycles in KNKTD OS

In short: KNKTD OS is fashion PLM software for brands that design in-house and produce with external factories. Styles, lifecycles with stage deadlines, versioned techpacks, boards, suppliers and size charts live in the same workspace as inventory, purchase orders and Shopify, so an approved style becomes a sellable product without re-entering a single measurement.

Most fashion PLM software ends at the approved sample. The techpack goes to the factory, and the rest of the business — the purchase order, the stock, the Shopify listing, the parcel — starts again in different tools with the same data typed in a second time.

The product development module in KNKTD OS is built so that hand-off does not happen. This article walks through what the module contains, in the order a style moves through it.

What fashion PLM software has to do

A product lifecycle management system for apparel answers a short list of questions, every day, for every style in development:

• What is this style, who designed it, and for which season?
• Which colourways, sizes and materials does it use, and what does each cost?
• Which stage is it in, who owns that stage, and is it late?
• What exactly does the factory need to make it, and which version did we approve?
• Once approved, what does it become in the warehouse and on the storefront?

Generic project tools answer the third question. Spreadsheets answer the second, until two people edit the same file. A PLM answers all five — and KNKTD OS is designed so the fifth is a consequence of the first four rather than a separate project.

The style is the record everything else hangs off

A style in KNKTD OS carries its number (generated by a numbering rule you configure), designer, season, product type, colourways, size chart, points of measure, materials from the shared materials library, media, supplier and costs.

Costs are recorded per production run, not as one number that gets overwritten. A re-run at a new price keeps the old run's cost on record, so a margin report from last season still describes last season.

Because the style holds its size chart and colourways, the variant matrix a factory and a storefront both need — every size in every colour — exists before anyone creates a product.

Lifecycles with stage deadlines, not a status dropdown

Every brand runs development differently, so lifecycles are custom. A lifecycle is an ordered set of stages — sketch, proto, first fit, second fit, pre-production, approved, whatever yours are — each with an owner and a deadline measured from the stage before it.

Two lifecycle types exist: development and production. A style finishes development, is handed off, and starts a production lifecycle with its own stages, so "approved" and "in production" are not the same column with a different colour.

A style can also branch: a variant that shares a body but changes the fabric or a detail starts from the parent's data and follows its own path. The lifecycle flow is drawn as a diagram so a newcomer can see where a style can go next without reading a manual.

Overdue stages raise notifications, in the app and by email, to the people who chose to receive them. The Tracker lists every style in flight by stage, so a Monday meeting starts from one screen rather than one message thread per style.

A techpack the factory can build from

The techpack is generated from the style record, not drawn separately. It contains:

• Annotated sketches — front, back and detail flats with callouts pinned to the drawing.
• The bill of materials, from the materials library, with placement and consumption.
• The measurement specification, per size, with tolerances and grading notes.
• Construction, stitching, labelling, care, packaging and artwork placement.
• Costing per run.
• Fit history — what changed after each sample, kept across versions.

Every regeneration creates a new version, so the factory's copy and the approved copy can always be compared. A readiness check lists what is still missing — an unpriced material, a size without measurements — before the techpack is sent. Generated techpacks render read-only, with a preview route, so nobody edits a version that has already gone out.

For a fuller argument on why a bill of materials is not a techpack, see the Katana comparison.

Boards and the tracker

A Board is a collection or drop: the styles that launch together. Boards carry a launched state that follows the linked Shopify collection's publish date, or a date you set by hand, so "is this drop live?" is answered by the system rather than by whoever last checked the store.

Where the tracker shows every style by stage, the board shows a season by launch. Designers, merchandisers and buyers tend to live in one or the other.

Suppliers, size charts and the libraries

The Supplier profile is where development meets buying: lead times, order minimums, the open purchase orders, what is payable, and a performance record built from actual receipts — on-time, short-shipped, defective.

Size charts drive variants, and per-chart size curves (from the chart or learned from sales) pre-fill purchase orders. Measurements, care guides, colours, models and product types are shared libraries so a term is defined once and reused across every style.

Designers are records too: a per-designer bonus engine can pay out on the sell-through of the styles they designed, from the same sales data the reports use.

Approval turns the style into a product

This is the step other PLMs leave to you. Approving a style in KNKTD OS:

1. Creates the inventory product with every variant from the style's size chart and colourways.
2. Generates SKUs by your rule, and barcodes for labels.
3. Recommends an HS code from a 6,900-code database, with country of origin, so customs data exists before the first international order.
4. Pre-fills a purchase order to the style's supplier, split across sizes by the size curve.

From there the product lives in the warehouse module, is published to Shopify from the online store module, and is sold and shipped through the orders module. The style stays linked to its product, so a fit change in a later run is a new techpack version on the same record.

Who it is for, and who it is not for

KNKTD OS suits a brand that designs its own product, works with external factories, and sells mainly through Shopify. Two to fifty people is the typical team.

It is not manufacturing software. If you schedule cutting rooms, assign operators and consume raw materials on your own floor, you need an MRP for that job and could still use KNKTD OS for everything around it.

Pricing

Every plan includes all eight modules — product development is never a separate licence. Plans start at $100 USD per month for two team members, then $150 for five, $275 for ten and $500 for unlimited seats. There is a 14-day free trial and onboarding is included. See current pricing.

Bottom line

Fashion PLM software earns its keep when the techpack is right and the approval means something. KNKTD OS does both, and then makes the approval do the work: the product, its SKUs, its customs data and its first purchase order exist the moment the style is approved, in the system that will sell and ship it.

Frequently asked questions

What is fashion PLM software?

Product lifecycle management software for apparel and accessories brands. It holds each style, its materials, measurements, construction and costs, moves the style through development stages such as sketch, sample and approval, and produces the techpack a factory builds from. KNKTD OS adds what most PLMs stop short of: the approved style becomes the inventory product, purchase order and Shopify listing in the same system.

Does KNKTD OS generate techpacks?

Yes. A techpack is generated from the style record — annotated sketches, bill of materials, measurement specification with tolerances, construction, care, packaging, artwork, costing and fit history — versioned each time it is regenerated, with a readiness check that lists what is still missing before it is sent to a supplier.

Can I use KNKTD OS for PLM only, without the inventory and order modules?

Every plan includes all eight modules, so nothing stops a brand using only product development at first. Most teams connect Shopify and turn on inventory and orders once their first styles are approved, because that is where the data already flows.

Is KNKTD OS a manufacturing system?

No. It manages the brand-side workflow — specification, approval, buying and everything after — with external factories. It does not schedule production floors or track material consumption inside a factory.
