You've scaled your revenue. Your operations haven't kept up.

Most fast-growing DTC brands reach a point where spreadsheets stop working. 16 tabs, copy-pasted supplier data, version chaos. One missed reorder, one stockout before a peak, and suddenly revenue leaks, cash gets stuck, and the team is firefighting instead of growing. Rewize is the inventory forecasting and planning layer your stack is missing. It connects your channels, learns your demand patterns, and tells you exactly what to buy, when, and from whom, for all your SKUs.

Your current situation

  • No single view: data lives in spreadsheets and silos.
  • Reorders and safety stock are guesswork.
  • Mistakes happen more often and get more costly.

With Rewize

  • One demand view from channels and sales history.
  • What to buy, when, and from whom, without guesswork.
  • A planning layer on your stack, no rip-and-replace.
Rewize

Plan your inventory with confidence

What to buy as a fast-growing D2C brand, when, and how much. For every SKU and every channel, without tying up more cash than you need to.

Forecasting per SKU and per channel

See how many days of stock you have left per product, and when to reorder

Rewize reads your sales history per channel and factors seasonality, growth, lead times, campaigns and even your own intuition into your forecast. Filter on bestsellers or on every SKU from a single supplier, and get a heads-up before a product runs out. Manufacturing your own finished goods? Forecast raw materials and components as well.

The forecast is clear and straightforward, it saves me time by giving me exactly what I need without any hassle.

Purchasing advice for every SKU

As a D2C brand you can't reorder every day: every order has to count

Rewize calculates per SKU how much you need until your next delivery arrives, and takes your MOQs, volume discounts and container space into account. You see straight away what the order costs and how many days of coverage it will provide. The purchasing advice includes the reasoning behind it. Accept it as is, adjust it through Rey, or ignore it: the decision stays yours.

Giving us an accurate view of our stock and when to place new POs has been game changing!

All your channels and warehouses

Your entire supply chain comes together in one forecast

Make well-founded decisions for every stock location, without depending on how up-to-date your last export is. Your forecast now reads your source data in real time. So you stop running out of stock on Bol.com or Amazon, and you don't lose revenue or hard-won marketplace rankings.

Rewize has helped me streamline inventory tracking and planning. Because of this we had grown a lot and it decreased our work load.

Grip on your inventory

How much revenue is at stake right now?

Within five seconds you'll see which products are about to run out of stock, how much cash is tied up in your inventory, and which open tasks you need to tackle to keep the operation running. Build your own reports and schedule them, for example every Monday morning in your inbox and your team's.

The UI is extremely clean, genuinely the cleanest I've seen of any inventory app. Simple, thoughtful, and everything laid out in a way that makes sense.

Rey

Next month you're running a big promotion, but your current forecast knows nothing about it

Tell Rey, or your own AI through MCP, in plain language what's changing: a promotion, a product launch, or a supplier delivering late. Rey works it through to every SKU, comes back with an adjustment to your forecast, and lays out different scenarios to choose from. Keep sparring until you're 100% on board. Then Rey applies it across your entire forecast.

Accurate purchase recommendations in 1-7 days

Thanks to native integrations and fast support from our side, we can help you switch from your current tools and/or Excel in just a few days.

What our customers say

Built by operators who lived the problem.

Rewize was built by founders who ran fast-growing eCommerce brands. We'd spend nights buried in spreadsheets, guessing reorder quantities, and fretting over stockouts. We nearly went bankrupt due to overstocking on 3 separate occasions. We built Rewize to remove that friction, not to create another tool.

We were buying on gut feel and paying for it in stockouts and dead stock. I never want to plan a season that way again.

Thijs Roelofs
