PLM vs ERP for fashion brands
A PLM is where a fashion brand develops products; an ERP is where it runs orders, stock and money. How they differ, whether you need both, and the gap between them.
The short answer: a PLM (product lifecycle management) system is where a fashion brand develops its products: styles, tech packs, materials, costing and samples. An ERP (enterprise resource planning) system is where it runs the business: purchase orders, inventory, production, finance and sales. A style is born in the PLM and becomes SKUs and orders in the ERP.
What a PLM does for a fashion brand
- Line planning: which styles go into a season or drop.
- Tech packs: sketches, measurements, materials, construction and labels, with every version kept.
- Materials and colour: fabric and trim libraries, and approved colour standards.
- Costing: each style’s cost built up against its target.
- Sampling: proto, fit and PP rounds, and the comments on each.
- Calendars: the time and action milestones from order to ex-factory.
- Supplier collaboration: sharing specs with mills and factories.
Design, product development, merchandising, sourcing and QA live in it.
What an ERP does for a fashion brand
- Purchasing: purchase orders, goods received and supplier invoices.
- Inventory: stock across warehouses, stores and marketplaces.
- Production planning: production orders and materials, for brands that manufacture.
- Sales and distribution: sales orders, fulfilment and channel integrations.
- Finance: actual costs, payables, receivables and GST.
Buying and planning, operations, the warehouse and finance live in it.
PLM vs ERP at a glance
| PLM | ERP | |
|---|---|---|
| Main job | Develop the product | Run orders, stock and money |
| Unit of work | The style, before it’s a SKU | The SKU, the order, the invoice |
| When it matters | Concept to PP approval | PO to sale |
| Main users | Design, merchandising, sourcing, QA | Buying, planning, operations, finance |
| Typical records | Tech packs, BOMs, costings, samples | POs, receipts, invoices, stock |
| Updated by | Your team, and sometimes suppliers | Your team, often from transactions |
Do you need both?
Most growing brands end up with both, sometimes in one suite. As rough rules of thumb:
- A few dozen styles and one or two factories: spreadsheets and a well-kept T&A calendar can work. Accounting and inventory software usually comes first, because money and stock demand it.
- Hundreds of styles and several mills and factories: a PLM starts to pay off, because version control, sampling and costing changes are where time and margin leak.
- Many channels and warehouses: an ERP becomes essential.
Many mid-sized Indian brands run an ERP or accounting system for orders and money, Excel for development, and WhatsApp for everything in between.
What neither system records
Both systems share one gap: they record what someone enters. In fashion, most decisions are made before anyone enters them, in WhatsApp groups, calls and emails with mills and factories.
- The PLM has tech pack v3, while the factory cuts from the v2 it got on WhatsApp.
- The ERP has the PO at ₹418, while the price agreed on the call was ₹412.
- The T&A calendar says bulk fabric arrives on the 6th, while the mill said on a call it will be the 12th.
Neither system is wrong. They’re behind. And the reasons behind each value, such as who approved it and what it depended on, aren’t in either.
Where Spurby fits
Spurby sits between where decisions are made and the systems that record them. It reads the WhatsApp, email and calls your team switches on, keeps one live record per style with each value linked to its source, checks PLM and ERP documents against what was decided, and drafts the follow-ups. It works alongside a PLM or ERP, or as the record for brands that don’t have a PLM yet.
Questions
- Is PLM the same as ERP?
- No. PLM (product lifecycle management) manages how a product is developed, from concept to the approved pre-production sample. ERP (enterprise resource planning) manages orders, inventory, production and finance once the product exists.
- Can an ERP replace a PLM for a fashion brand?
- Some ERPs include product development modules, but they’re usually built around SKUs and transactions rather than the back-and-forth of tech packs and sampling. Brands with many styles and suppliers usually end up needing PLM-style tools for development.
- What comes first, PLM or ERP?
- Usually the ERP, or accounting and inventory software, because orders, stock and money can’t wait. A PLM tends to follow once the number of styles and suppliers makes development hard to manage in spreadsheets.
- What is PDM?
- Product data management. It’s an older term for the part of PLM that stores product data, such as specs, drawings and files, without the workflow around it.
