# Merchmix > Merchmix is a retail operating system that connects planning, buying, inventory, allocation, supplier workflows and store execution in one platform. Merchmix helps retail teams reduce stock distortion, margin leakage and manual firefighting as they scale. Merchmix Intelligence surfaces recommendations inside the workflow rather than in another dashboard, so reads turn into actions, approvals and tracked outcomes. Your ERP stays the system of record: publish-back is approval-first and fully auditable. 12 retailers run on the platform, from roughly $50M to $900M in revenue, from trend-led brands to large value retailers. Built by people who ran planning at M&S and ASOS, with a global team across Boston, London, Sydney and India. ## Guides - [What is a WSSI?](https://merchmix.co/guides/what-is-wssi): A plain English guide to Weekly Sales, Stock and Intake: what every row means, a worked example, and how it drives open-to-buy. - [What is open to buy?](https://merchmix.co/guides/what-is-open-to-buy): The OTB formula in plain English, a worked example of spending it, and why lead time decides what you can actually buy. - [What is allocation and replenishment?](https://merchmix.co/guides/what-is-allocation-replenishment): How retailers decide where stock goes first, how it gets topped up, and where the rules break down. - [What is a retail markdown?](https://merchmix.co/guides/what-is-a-retail-markdown): Permanent price reductions explained: how they differ from promotions, what they cost in margin, and when to take them. - [What is assortment planning?](https://merchmix.co/guides/what-is-assortment-planning): How retailers decide which products to offer, in what breadth and depth, across stores and channels for a season, with worked examples and store clustering. - [What is size curve optimization?](https://merchmix.co/guides/what-is-size-curve-optimization): A size curve is the split of demand across sizes.
