Ecommerce demand forecasting predicts how many units of each product your online customers will order, and when. Demand planning turns that forecast into buying decisions: what to reorder, how much, and which warehouse should hold it.
We run both for online brands. Our team builds SKU-level forecasts, sets reorder points and safety stock, plans for peak season and reviews the numbers with you in S&OP meetings.
Online sales rose 12.2% year over year and made up 17.1% of US retail in the second quarter of 2026, according to the U.S. Census Bureau. Each new online order is one more chance to sell out of a winner or sit on stock nobody wants.
A forecast for an online store predicts unit sales per product and channel, using past orders and the events coming up next. It sits at the front of supply chain logistics, because every later step depends on how much stock you expect to need.
Forecasting and demand planning are two halves of one job. The forecast says what customers will probably buy. The plan decides what you buy in response: order quantities, reorder points, safety stock and where each unit sits.
Online stores need their own approach because their demand moves fast. A single promotion, a viral post or a change to a marketplace listing can lift a product’s sales sharply within days.
Our demand planning services cover SKU forecasts, reorder points and safety stock, seasonal plans, S&OP meetings, warehouse replenishment and stock alerts.
We forecast each product on its own rather than by category. A category average hides the fast seller that runs out and the slow one that ties up cash.
Not every SKU deserves the same attention. An ABC analysis ranks products by value, so the items that drive most of your revenue get the closest watch.
A reorder point is the stock level that triggers a new purchase order. Safety stock is the buffer you hold for a late supplier or a sudden spike in orders.
We set both for each SKU from your sales history and supplier lead times. Together with an order quantity such as the economic order quantity, they tell your buyers when to order and how much.
Peak season needs stock in place before the orders arrive. We build the seasonal curve into each forecast and plan inbound shipments early enough to land before the rush.
Brands that prepare their supply chain for peak season demand early avoid paying rush freight to catch up later.
S&OP, short for sales and operations planning, puts your sales plans and our stock plans side by side. In these meetings we review the forecast with you, flag risks and agree what to buy next.
It works much like S&OP consulting. The difference is that we can also hold and ship the stock we plan.
We move stock between our Memphis, Riverside and Carolina, Puerto Rico warehouses when one site runs low and another has spare units. That keeps each site stocked for the customers it ships to.
You see live stock levels through your inventory view, and low-stock and reorder alerts flag what needs buying before it runs out. Our inventory management services handle the counts and lot tracking underneath.
Five steps take a forecast from raw order history to a buying plan you can act on.
A forecast starts with order history by SKU and channel, plus current stock and supplier lead times. We connect to the sales channels and systems you already use, so that data reaches us directly.
Raw history hides distortions. Weeks when a product sat out of stock show low sales that were really lost sales, and a one-off promotion looks like normal demand. A sound forecast corrects for both first.
History only shows the past. Planned promotions, product launches, holidays and price changes all shift demand, so they enter the forecast as known events.
The forecast becomes a buying plan: how much to order, when, and for which warehouse. Reorder points and safety stock then tell your buyers when to act.
Each cycle, compare the forecast with what actually sold and adjust. In our S&OP meetings we review that gap with you and change the plan before it turns into a stockout.
Three method families cover most online stores: time-series models for steady sellers, judgment-based forecasts for launches and causal models for promotions.
| Method | How it works | Best for | Data it needs |
|---|---|---|---|
| Time-series models | Projects past sales patterns forward, seasonality included | Products with a steady sales history | A long, clean history of sales by SKU |
| Judgment-based forecasts | Uses buyer and market knowledge where data is thin | New products and trend items | Comparable products, pre-orders, market research |
| Causal models | Measures how promotions, price and ad spend move demand | Brands that run frequent promotions | Campaign calendar, price history, ad spend |
A forecast can blend all three. We use planning software, including AI models, to run the numbers, and we review the results with you in S&OP.
Selling online, wholesale and on marketplaces from one inventory makes forecasting harder, because each channel orders differently. A website sells one unit at a time, while a wholesale buyer takes a pallet in one order.
We keep retail, wholesale, online and FBA stock in one count across our warehouses. Each channel gets its own forecast, and the plan draws on one pool of stock.
That way a large wholesale order shows up in the plan before it empties the shelf your website sells from. Our omnichannel fulfillment services ship all of those orders from the same stock.
There are three ways to run demand planning: your own planner, forecasting software you run yourself, or a 3PL that also holds the stock.
| In-house planner | Software only | 3PL-run planning | |
|---|---|---|---|
| Who builds the forecast | Your own hire | Your team, using the tool | Our team |
| Sees live warehouse stock | Through reports | Only if connected | Yes, the stock sits in our warehouses |
| Plans moves between warehouses | Your team | Your team | We do |
| Main cost | A salary | A software license | Quoted to your account |
| Best when | Volume justifies a full-time role | Staff have time to run it | You want planning tied to the stock we hold |
Outsourced demand planning makes the most sense when a 3PL already stores your goods. The team that plans the stock is then the team that receives and ships it, through our 3PL ecommerce fulfillment.
You can also buy demand planning on its own, without moving your stock to Cura Resource Group.
Measure accuracy with four numbers: forecast error, bias, stockout rate and weeks of cover.
Track them per SKU, not only in total. Review them in each S&OP meeting so the plan improves every cycle.
A demand forecast predicts how many units customers will buy and when. Demand planning decides the response: how much to order, when to reorder, how much safety stock to hold and where. The forecast comes first, and the plan turns it into purchase orders.
You need order history by SKU and channel, current stock levels, supplier lead times and a calendar of planned promotions and launches. More history helps, especially for seasonal products. For a new product with no sales yet, comparable products and pre-orders fill the gap until real sales data builds up.
Yes. A new product starts with a judgment-based forecast built from comparable products, pre-orders and market research. Once real orders arrive, the forecast shifts to the actual sales data. The sooner those orders come in, the sooner the forecast leans on facts rather than comparisons.
Safety stock is the extra stock you hold as a buffer against a late supplier or a sudden jump in orders. We set it for each SKU from how much its demand varies and how long its supplier takes to deliver. Too little leads to stockouts, and too much ties up cash.
An S&OP meeting brings your sales plans and our stock plans together. We compare the last forecast with actual sales, review upcoming promotions and launches, flag supply risks and agree what to buy next. The result is one plan that your sales team and our warehouse team both work from.
Yes. We use planning software, including AI models, to analyze sales history and spot patterns across your SKUs. The software runs the numbers, and we review the forecast with you in S&OP meetings before it shapes a buying plan. The final call on what to buy stays with you.
Yes. You can buy demand planning on its own, without moving your stock to our warehouses. When planning and storage run together, though, the forecast and the stock sit in one system. Our team can then move stock between sites as the plan changes, and the alerts come from the same count.
Use short horizons, a few weeks out, for replenishment, and longer ones, several months out, for seasonal buys. The right horizon also depends on supplier lead time. If a supplier needs three months to deliver, your forecast has to look at least three months ahead.
