Inventory Forecasting and Replenishment: reorder points from your sales on every channel
Inventory forecasting answers one question for each SKU: how many units will sell before the next delivery arrives. InfiPlex answers it every day. It reads each SKU's sales across every connected channel over three time windows, weights recent sales against the long-run rate, converts that into expected demand over your supplier lead time, adds your safety stock, and flags the SKU the day on-hand stock reaches that reorder point. The result is a daily Restock Report by email, the same SKUs highlighted on the Inventory page, and a restock list an AI agent can turn into a reorder sheet with suggested quantities. It is part of the InfiPlex inventory system on every plan.

How it works
How InfiPlex forecasts demand and sets the reorder point
A forecast built on one sales window is either jumpy or slow. InfiPlex blends three, so a SKU that sold steadily for six months and doubled this month gets a reorder point that reflects both facts. Here is the worked example from the settings page, with a 14 day lead time:
Sales window

Weight
Expected demand over a 14 day lead time

3.8 units
Safety stock
5 units
Reorder point
16.8, shown as 17
Each row is the same idea: units per day over that window, times the days your supplier takes to deliver, scaled by how much you trust that window. When on-hand stock for the SKU reaches 17, it is on the next report. The formula and all eight settings are written out in the Restock Alerts guide.
What you get each day
The InfiPlex Restock Report and the reorder sheet
Three outputs come from the same calculation: a Restock Report emailed once a day, the same SKUs highlighted in orange on the Inventory page, and a restock list an AI agent can read through the InfiPlex MCP server with Claude, Cursor, ChatGPT through Codex, or any MCP client.

All six have less cover than their lead time, so each is marked order now. HX-2040 runs out first.

The daily email carries the reorder point, on-hand stock, and sales for each window. The agent adds what a buyer needs next: seven day velocity, days of cover, and a suggested quantity. The nightly restock agent guide has the instruction file and the cron line, and it runs on a read-only key.
Tuning
Tune the forecast to each supplier and each SKU
Four controls shape every reorder point. All of them live under Settings > Base Settings > Warehouse, with per-SKU values in the SKU Utilities tool or the Price & Inventory upload.
Lead time per SKU. A supplier that takes 30 days and one that takes 5 should not share a reorder point. Set the account default, then override any SKU.
Safety stock per SKU. The floor you never want to drop below, added to every reorder point. A SKU with no recent sales still reorders at this level.
Window lengths. 180, 60, and 14 days are defaults. Shorten them for fast-moving catalogs or lengthen them for slow ones.
Weights. 50, 35, and 15 by default, totaling 100. Move weight to the short window for seasonal products, or to the long window for steady ones.
Where it fits
InfiPlex forecasting next to a standalone forecasting app
Replenishment tools are usually bought as a separate subscription and connected to each sales channel. In InfiPlex the forecast sits inside the system that already has your orders and your inventory.

A forecast is only as good as the sales and stock numbers underneath it. InfiPlex already holds both for multichannel inventory sync, so the reorder point is computed on the same numbers your channels are sold from. For the SKUs that sell the most and earn the most, see the top selling SKUs report and the SKU profitability report.
Frequently asked
Inventory forecasting and replenishment questions, answered
What multichannel sellers ask before they rely on InfiPlex for reordering.
A reorder point is the on-hand quantity at which you need to place a restock order so the new units arrive before you run out. It equals the units you expect to sell during your supplier lead time, plus a safety stock cushion.
It takes units sold over three windows, 180, 60, and 14 days by default, converts each to expected sales over your delivery lead time, weights them 50, 35, and 15 percent, and adds them together. Safety stock is added on top. The Restock Alerts guide writes out the formula and every setting.
Yes. Orders from every connected marketplace, cart, and EDI retailer land in InfiPlex in one format, so a SKU's sales on Amazon, Walmart, Shopify, and wholesale all count toward the same forecast.
The daily Restock Report tells you when to reorder and shows sales by window so you can size the order. For a suggested quantity, the nightly restock agent reads the same list and adds seven day velocity, days of cover, the split by warehouse, and a suggested order quantity as a CSV.
Yes. The account defaults apply to every SKU, and any SKU can carry its own lead time and safety stock, set in the SKU Utilities tool or by upload. See using the SKU Utilities tool.
Shift weight toward the short window. Putting more of the 100 percent on the 14 day range makes the reorder point follow what is selling now, and putting more on the 180 day range holds it steady through spikes.
Restock Alerts are built for the stock in your own warehouses. Stock in marketplace fulfillment networks is read into InfiPlex by SKU and managed through the FBA inbound shipments integration and the guides for WFS, FBA, and 3PL.
Restock Alerts are included on every InfiPlex plan, with no charge per SKU or per warehouse. The AI agent route uses the MCP server, which is included with API access. See pricing.
