Demand Planning

Know what you'll sell months ahead.

Forstock reads your sales history and tells you what each product — each size, each color — is likely to sell next, months in advance. No spreadsheet to babysit, no formulas to maintain. A plan you can read at a glance, and change when you know something it doesn't.

Most stores don't have a data problem. They have a “nobody checked” problem.

The conversation on the left never happens

Shopify already shows you the numbers. What's missing is someone who checks them every morning and says what to do. That's the job Forstock takes over: the forecast turns into exact order dates and quantities — before a customer finds the gap for you.

A forecast that sees what your sales report can't.

OUT OF STOCK
Actual salesTrue demand
True demand

Counts the sales your stockouts hid.

When a product sells out, its sales drop to zero — and a forecast that only reads the report concludes nobody wanted it. Forstock spots those sold-out weeks and rebuilds what you would have sold, so you plan for real demand, not for the ceiling your stock ran into.

Launches

Forecasts a launch with zero history.

A brand-new SKU has no sales to learn from. Forstock models it on the products it most resembles — category, price, seasonality — so your first order is grounded in real patterns, not a blind guess.

You stay in control

Every product gets the forecast that fits it.

Your best-sellers have years of history; half your catalog barely has any. Use the smart forecast where there's real history and a simple average for the rest — and switch either one, per product. Tell Forstock how far back to look and how fast you're growing, and it builds the plan around that.

  • Smart forecast or simple average — you pick, per product
  • Set how far back it looks, and your growth rate
  • Change your mind on any product, anytime

Your numbers, your call — try it

Know something the forecast doesn't? Change it.

Nobody knows your launches, promos, and wholesale orders like you do. Open the plan and put your own number on any month, product, or location — Forstock plans and reorders around your call, not just the model's. Go ahead: grab November and move it.

  • Edit any product, month, or location by hand
  • Your numbers flow straight into reordering
  • Discard or save — nothing moves until you do

Other tools forecast on industry averages — and miss the SKUs that actually move your business.

Forstock forecasts every variant on its own — per SKU, per location, down to the day it runs out.

01 / Fits your business

No one-size-fits-all math.

Your hero products and your slow movers behave nothing alike — so each one gets the forecast that suits it, and you can change the choice on any product.

02 / Shows its work

Every number can explain itself.

Each forecast breaks down into everyday sales, growth, season, and promo lift. When a number looks wrong, you can see exactly why it says what it says — and argue with it.

03 / Never goes stale

Always working from yesterday's sales.

Every order, refund, and exchange updates your numbers. Refresh the forecast whenever you like — the plan keeps pace with what's actually happening in your store.

What operators say about their forecasts.

Very easy to use stock and inventory tool. Great for planning and wonderful customer service. They truly are here to help you, as the shop owner, succeed. I like the ABC analyses and the Reorder feature.

Finally a tool that works. We'd tried a few inventory tools and always went back to spreadsheets to verify the numbers ourselves. Forstock is the first that actually feels close to how we think about reordering — a clear view of what to order and when.

Forstock makes inventory forecasting much easier and helps us stay ahead of stockouts without over-ordering. The interface is simple, clear, and actually actionable — great for control over inventory planning and cash flow.

Really happy with Forstock. Rami and his team built something that feels practical and easy to use. It helps a lot with planning reorders without going back to spreadsheets all the time.

Forstock has become a real ally in running our store. It lets us anticipate our stock needs calmly, avoid stockouts, and keep replenishment under control. The interface is intuitive, clear, and focused on concrete decisions — highly recommend it.
