Supply Planning
What Is a Supply Plan in Moselle?
A Supply Plan is a network-wide order schedule. For every item at every warehouse, over every month in your coverage period, it shows what you start with, what you expect to sell, what is arriving, what is moving between your own sites, and what you will have left — and it proposes the purchases, production runs, and transfers needed to keep every site covered.
It is built on the same forecast as a replenishment plan, but it reads your Supply Chain map to understand how stock actually reaches each location: which supplier or factory feeds which warehouse, how long each route takes, and which warehouses can ship to one another.
Three kinds of order live in a supply plan:
Purchase
Buy finished goods from a supplier, landing at one of your warehouses
Production
Have a manufacturer or co-packer make product for you, then ship it to a warehouse
Transfer
Move stock you already own from one of your warehouses to another
Every order carries three dates: the date you must order by, the date it ships, and the date it lands. The plan is organised around those dates, so it tells you not just how much but when you have to act.
Before you build a supply plan, two things must be set up:
Your Supply Chain map — suppliers, warehouses, and channels connected on the canvas under Operations > Inventory > Supply Chain, with lead times on every connection. This is where the plan learns who supplies whom and how long each route takes.
Supplier catalogs — each supplier's list of the SKUs they carry, with price and order terms (MOQ, case pack, production lead time), under Suppliers > [supplier] > Catalog.
Without a map, the plan has no routes to plan on. Without catalogs, it has no vendor to place orders with and no order terms to respect. See Where Do I Set Supply Planning Conditions? for exactly what lives where.
Supply Plan vs. Replenishment Plan: Which Should I Use?
Both plan types start from your forecast and end in purchase orders. The difference is how much of your supply chain they take into account.
Replenishment Plan
Supply Plan
Scope
One warehouse (or all warehouses treated independently)
Your whole network — every warehouse planned together
Order types
Purchases from suppliers
Purchases, production runs, and transfers between your own sites
Lead times
One lead time per item or supplier
Production time from the supplier catalog plus transit time for each route on the map
What it answers
"How much of each SKU should I reorder?"
"Where should stock come from, where should it go, and when must I act?"
Setup needed
Forecast + supplier lead times
Forecast + Supply Chain map + supplier catalogs
Best for
Straightforward reorder cycles, single-warehouse businesses
Multi-warehouse networks, co-packers, 3PLs, businesses that rebalance stock between sites
Choose a Supply Plan when…
You have more than one warehouse and stock flows between them — a central DC feeding regional sites, a 3PL and an FBA warehouse, or a factory warehouse shipping to a fulfilment centre.
You need transfer recommendations. A replenishment plan can only tell you to buy more. A supply plan can tell you that a warehouse's shortfall is best covered by moving stock you already own.
You want to see the network, not a list. The supply plan shows every warehouse's starting stock, demand, arrivals, transfers, and ending balance side by side, month by month.
Your supply chain has stages — a manufacturer makes the product, ships it to your warehouse, and you ship onward — and you want each stage's lead time counted.
Stick with a Replenishment Plan when…
You buy finished goods for a single location and never transfer between sites.
You want the quickest possible path from forecast to a reorder list.
You have not yet mapped your supply chain or built supplier catalogs.
How Does the Supply Planning Workflow Work?
Time Required: 10 minutes for your first plan, then a few minutes per review cycle Difficulty: Intermediate
Set up your map and catalogs
Map suppliers, warehouses, and channels on the Supply Chain canvas with lead times on every connection. Upload each supplier's catalog with MOQ, case pack, and production lead time. Optionally set a safety_stock custom attribute on your products.
Create and build the plan
From Production in the left sidebar, click Create Production Plan, choose Supply Plan, name it, pick a coverage period and forecast, and let Moselle build the first version.
Create a Supply PlanTriage in Total Overview
Start on the Total Overview tab to see, per SKU, how many units are suggested, how many you have already staged, how many transfers are proposed, and how much demand is still unserved.
Supply Plan ViewsWork the plan in Monthly Breakdown
Switch to Monthly Breakdown to see each SKU month by month and warehouse by warehouse. Expand a warehouse row to see where its numbers come from, edit quantities and dates, add orders or transfers, and stage what you agree with. Click the list icon on any SKU or warehouse row to see all of its orders in one panel, or switch to a built-in view — Days On Hand to check cover, Replenishment to work purchases, Transfer to work moves between warehouses.
Stage, then place
Accept suggestions by staging them — staged orders are yours and survive rebuilds. When you are ready to commit, place them: Moselle creates real purchase orders grouped by supplier, warehouse, and arrival date. To place many at once, ask Mo — "place all my September and October orders" — and approve the confirmation card.

Frequently Asked Questions
Do I need a Supply Plan if I only have one warehouse?
Answer: Usually not. With a single warehouse and no transfers, a replenishment plan gives you the same reorder answer with less setup. A supply plan becomes valuable once stock moves between locations or a manufacturer sits between the supplier and your shelf.
Does a Supply Plan replace my Replenishment Plans?
Answer: No. Both types coexist on the Plans list and are built from the same forecast. Use whichever fits the question you are asking.
What happens if my Supply Chain map is incomplete?
Answer: The plan can only route stock along the connections you have drawn. A warehouse with no source or inbound lane will show its demand as unserved because nothing can reach it. Check the Network problems panel on the Supply Chain page and clear any findings before building.
Does a Supply Plan send orders to my suppliers?
Answer: No. Placing an order records a purchase order inside Moselle. Sending it to the vendor is a separate step you take from the Orders page, exactly as with any other purchase order.
