xMatix Inventory tracks what stock you hold, where it is, and what it is worth. Its backbone is the inventory ledger: every movement — a receipt, a shipment, a transfer, an adjustment — is recorded as a posted entry, and on-hand stock is the running position those entries have moved rather than a number anyone types. On top of the ledger sit branch-to-branch transfers with a real in-transit state, stock adjustments, lot-level tracking, a perpetual costing engine that values stock under the method your accounting policy chooses, and period balances that roll it all up for comparison. This section explains each piece and the screens where you work with it.
Where the screens live
Inventory work happens in the Inventory app. Its navigation bar carries the documents you create and the statements you read:
| Navigation entry | What it is for |
|---|---|
| Fulfilment Orders | The fulfilment documents that allocate and pick stock for orders; covered in the warehouse and sales documentation. |
| Inventory Overview Dashboard | A dashboard page your administrators author for the app in Design Studio; what it shows is whatever they placed on it, so its tiles are a summary view, not a system of record. Read balances and values on Inventory Stock and Inventory Valuation. |
| Transfers | Move stock between branches or companies: outward release, in-transit tracking, inward receive and posting. |
| Adjustments | Correct on-hand stock with a document — damage, expiry, shortage, excess, hold, loan — and post it to the ledger. |
| Inventory Stock | The Stock Balance statement: available quantity per item for a company, compared by branch, period or year, with drills into lots and the item ledger. |
| Inventory Valuation | The Valuation Statement: quantity and carrying value per item and accounting book, with drills into cost layers and consumptions, and a rebuild of the period-balance cache. |
| Inventory Ledger | The append-only list of every posted movement, each linked to the document line that produced it. |
| Reports | The report library, including the inventory movement analyses. |
| More → Dashboards, Settings | Further dashboards and the Inventory settings list, including item lot types. |
Two lists you will use are not on the navigation bar: Item Lots (open from a lot link on a document or ledger entry, from search, or through a stock figure's Item lot details drill) and Item Inventory Attributes (the per-branch classification and replenishment rows). Accounting books and valuation policies — the configuration that decides how stock is valued — belong to the Finance Setup app, and the read-only inventory ledger settings live under Setup → Feature Hub → Inventory. Both are covered in the configuration reference.
What this section covers
The pages are ordered so that each builds on the ones before it:
- The inventory ledger — the concept everything else rests on: every movement is a posted entry, corrections post reversals, and the Inventory Stock page is where you read balances.
- Transferring stock between branches — the two-document transfer: outward release, the in-transit state, inward receive and posting, the selective variants and the single-step alternative.
- Adjusting stock — correcting on-hand quantities with an adjustment document, the reason types, and when an adjustment is the right tool versus a cycle count.
- Item lots and lot types — batch- and serial-level tracking: what a lot records, which fields the platform maintains, and how lots follow stock through movements.
- Inventory valuation and costing — perpetual costing from the ledger, cost layers and consumptions, accounting books, valuation policies, the Inventory Valuation page and the engine's current limits.
- Inventory period balances — how the ledger rolls up into per-period opening, inward, outward and closing figures in quantity and value.
- Item classifications — the ABC and FSN categories, where they are stored, and where auto-ordering, cycle counting and reports read them.
- Inventory configuration reference — for administrators: the inventory ledger settings, the item-master stock flags, and the valuation configuration.
- Troubleshooting inventory — what to check when stock or valuation looks wrong, and what a closed period blocks.
Three rules that hold everywhere
- Nothing moves stock until it is posted. Creating an adjustment, a transfer or their lines records intent only. Stock changes when the document's action runs (Post Inventory, Release Outward), and the reliable proof that a line reached the ledger is its Inventory Ledger reference — not a status label.
- Posted entries are never edited. Correcting a posted line makes the ledger add negated reversal entries and fresh entries for the new values; the originals stay. Read pairs of opposite entries as history, not as errors.
- A movement that would take a stock counter negative is rejected. The posting fails with an Insufficient stock message naming the counter, and nothing is written. The fix is always on the source document — quantity, lot or location — never on the ledger.
Who can do what
Access to the Inventory app and its screens is granted through the user's security profile and the app's page permissions, like every other xMatix app. Posting, release and receive are entity actions, so a profile can allow a user to create and edit documents without letting them post. Accounting books and valuation policies sit in Finance Setup and normally belong to finance administrators. If a user cannot see a screen described here, start with why a user can't see something.
Where Inventory ends and neighboring modules begin
Inventory owns stock truth: the ledger, transfers, adjustments, lots and valuation. Warehouse operations that act on that stock — cycle counting, picking, putaway, receiving at the bins and fulfilment execution — are covered in the warehouse documentation, and replenishment — reorder rules and automatic purchase suggestions — in the procurement documentation. Goods receipts and sales shipments post their stock effects through the same inventory ledger described here, so the reading skills from this section apply everywhere.
