Product data quality

You know the scene: a customer orders, the item doesn’t fit, and a return starts. Product data quality solves this early: complete, understandable facts speed decisions and cut returns. For local Swiss sellers the rule is simple—use precise fields and avoid vague phrases so buyers know what to expect. A quick term helps: metadata are short technical tags that describe a product, like material, measurements or colour. Keeping these tags consistent means your assortment behaves predictably across channels and makes it easier to plan replenishment and safety stock without last‑minute surprises. Imagine listing a lamp without socket size. The buyer receives it, the bulb won’t fit, and the return process ties up stock. Small, concrete notes in the listing prevent such cases. Clear starting data keeps shelves moving and reduces time spent on after‑sales work.

Key mandatory information: Buyers want to know what they get right away. Mandatory information here means the facts that allow someone to decide: brand, model, main dimensions, weight and what’s included in the box. These items are often what make the difference between a sale and a pause in checkout. Keep measurements consistent. Use centimetres for length and grams or kilograms for weight where possible. Present dimensions in a simple, repeatable order such as height × width × depth. Consistent data makes comparisons easy and supports accurate stock planning and order fulfilment. Concrete case: a shop lists cushions but omits filling height and outer cover size. Customers buy the wrong covers, returns increase, and stock gets tied up. Clear mandatory information protects revenue and reduces the administrative burden on staff.

Variants, measurements and traits: Products with variants need clear rules. Colour, size and technical versions should have separate SKUs or variant IDs. This prevents mix‑ups in orders and when restocking. For assortment planning the takeaway is to manage inventory by variant, not just by the master product. Images and short notes per variant are important. Two sweaters in different colours should have separate photos, and if a size runs small, say so. These details reduce returns and give precise signals about which variant needs replenishing sooner. Mini‑situation: a retailer lists one dress in three sizes without fit guidance and sees many returns. With size charts and variant identifiers, they quickly spot which size sells best and can set safety stock for that particular variant.

Data care for your assortment: Good data is ongoing work. Product data quality improves with simple habits: regular checks, a short update workflow and a clear person responsible. Set a weekly quick review for new listings and any supplier updates so your assortment stays reliable and your stock plans hold true. Use structured fields on platforms and in your shop. Fill availability, lead times and categories clearly. Platform fields like those offered by OpenDeal are neutral and slot into your processes. Consistent entries reduce buyer questions and help you forecast replenishment. One final practical habit: when a new product arrives, complete a short template with the essential facts before you list it. That small step prevents returns, keeps stock accurate and makes your replenishment planning much easier.
