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

Demand · Mayfair Top HandleStockout-adjusted

True demand

Counts the sales your stockouts hid.

When a SKU hits zero, your sales hit zero too — and a naive forecast learns the wrong lesson. Forstock spots those stockout gaps and rebuilds what you would have sold, so you plan against real demand, not the ceiling your inventory set.

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

Choose how every SKU is forecast.

Run AI Forecast on SKUs with real history, or Simple Average on the long tail — and override the method per SKU. Set the lookback window and a growth adjustment, and Forstock builds the plan around it.

  • AI Forecast or Simple Average, per SKU
  • Tune the lookback window and growth %
  • Override the method on any product

Your numbers, your call

Know something the forecast doesn't? Change it.

Nobody knows your launches, promos, and wholesale orders like you do. Open the plan and type your own number into any month, SKU, or location — Forstock plans and reorders around your call, not just the model's.

  • Edit any SKU, 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 / Calibrate

Tune the model to your business.

Choose AI Forecast or Simple Average per SKU. Long-tail items get the model that fits them — not a one-size-fits-all average that pretends.

02 / Decompose

See what's driving every number.

Forstock separates base demand, trend, seasonality, and promo lift — so when a number looks off, you can actually argue with it.

03 / Stay current

Always on your latest sales.

Every new order, refund, and exchange updates your actuals — and you can refresh the forecast whenever you want, so the plan keeps pace with what's really happening.

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.
