The process in one view
The inventory management process is a six-step cycle: set up the item master, stores and opening balances; receive goods on a GRN; issue, return and transfer material as documents; count physical stock against the book; adjust to reconcile the counted variance; and report — ledger, valuation, ABC, reorder and expiry. Step one happens once at go-live; steps two to six repeat for as long as the business holds stock. This page walks each step; the pillar guide, what is inventory management software, covers the system that runs it.
Step 1 — Set up: item master, stores, opening balances
Everything downstream reads from the item / material master: item codes and barcodes, description and grouping, separate units of measure for stock, sale, purchase and packaging, tax group, cost price and valuation basis, and — critically for the later steps — minimum (reorder point) and maximum levels, shelf life and issue method. Alongside the items you define the physical structure: stores and storage locations, plus the supporting masters for parties, units and taxes.
The last setup act is opening balances: importing per-item, per-location opening stock (with lot detail where batches apply) so the system's day-one picture matches the shelf. This matters more than it looks. Stock is a running balance — every future figure is the opening balance plus movements — so an error seeded at go-live propagates into every later report. Teams that rush this step spend their first quarter fighting phantom variances.
Step 2 — Receive: gate pass and goods receipt
Goods arrive; two documents capture the arrival. An inward gate pass records the vehicle and consignment at the gate. The goods receipt note (GRN) then does the stock work: it posts the received quantity into the receiving store, raising the running balance and writing a plus entry to the stock ledger. For batch-controlled goods, the receipt also creates the lot — batch number, production date, expiry date — which is what makes FEFO issue and recall tracing possible later.
Receiving is where accuracy is won or lost, because it is the moment quantities enter the system. Received-but-not-posted material is the classic drift: the stock is on the floor but not in the book, and every report is wrong until the GRN catches up. The discipline is simple to state and hard to keep: post the receipt when the goods land, not at the end of the week. Barcode-assisted entry from the barcode and automation layer makes that discipline cheaper to keep.
Step 3 — Issue, return and transfer
Stock leaves, comes back, and moves around — each as its own document on the shared movement engine:
- Material issue — stock out to production, consumption or delivery on an issue slip; the balance falls and the ledger records a minus. For lot-controlled items, FEFO discipline excludes expired lots and serves the nearest-expiry eligible lot first.
- Material return — previously issued but unused material comes back to stock on a return slip; the balance rises again, documented rather than quietly re-shelved.
- Stock transfer — quantity moves from one store or location to another. Net stock is unchanged, but both legs are recorded, so location-wise balances stay true.
- Reserve / de-reserve — stock earmarked for a purpose moves into a reserved quantity without leaving the store, so available stock reflects commitments.
- Outward gate pass — the vehicle-level record of material leaving the premises, closing the loop the inward gate pass opened.
The mechanics of how each movement type affects the balance — and how cancellations reverse them — are covered in depth in how inventory software tracks stock movements.

Step 4 — Count: physical stock taking
However disciplined the postings, physical reality drifts — breakage, spillage, mis-picks, theft, unrecorded returns. Physical stock taking is the verification step: pick the count scope and location, scan or select each item (or lot), let the system show the book quantity, and record the counted quantity against it. The count document captures the variance line by line.
Counting comes in three rhythms, all on the same flow: annual (the full year-end count), quarterly, and perpetual — cycle counting a rotating subset of items continuously, so verification never requires shutting the store. ABC classification typically sets the rotation, with high-value A items counted most often. Which rhythm suits which operation is part of the perpetual vs periodic inventory question.
The crucial property: the count records variance only. It does not change stock. That is the next step's job.
Step 5 — Adjust: reconcile the variance
Reconciliation is a deliberate, separate act: for each counted variance, a stock adjustment document posts the correction — an adjustment-increase where the shelf held more than the book, an adjustment-decrease where it held less. The adjustment updates the running balance (and lot detail where applicable) and writes its own ledger entry, so the correction is as traceable as any receipt or issue. Scrap removals follow the same documented pattern.
Step 6 — Report and decide
The cycle exists to feed this step. With movements posted and variances reconciled, the reporting layer turns records into decisions:
- Stock ledger — every movement with opening, in, out and running balance, traceable to its document.
- Item-wise and location-wise stock, valued — what you hold, where, and what it is worth at cost or lot rate.
- ABC analysis — items classified by value share (A ≥ 70%, B 30–70%, C < 30%) to focus counting and purchasing.
- Reorder-level alerts — items at or below their minimum flagged for replenishment before they stock out.
- Lot expiry and non/slow-moving — near-expiry lots bucketed by window; items with no movement surfaced for de-stocking.
These reports then drive the next receipts (what to reorder), the next issues (which lot first) and the next counts (which items, how often) — which is what makes the process a cycle rather than a line. The payoffs are quantified in the benefits of inventory management software.
The rule that holds it together
Every step above is an application of that one rule. Break it anywhere — a balance typed over, a receipt posted late, a count that "fixes" stock directly — and the cycle stops being self-verifying. Keep it, and any figure in any report can be explained movement by movement, which is the entire point of running a process instead of a spreadsheet.
Frequently asked questions
What are the steps of the inventory management process?
Six steps, in a repeating cycle: (1) set up the item master, stores and opening balances; (2) receive goods on a GRN, which raises stock; (3) issue, return and transfer material as documents; (4) count physical stock against the book quantity, recording variance; (5) post an adjustment to reconcile the counted variance; (6) report — stock ledger, valuation, ABC, reorder alerts, expiry and non-moving analysis. Steps 2 to 6 then repeat continuously.
Why do opening balances matter so much?
Because stock is a running balance, every future figure is opening balance plus movements. If go-live balances are wrong, every later balance inherits the error, and the first physical count becomes an archaeology exercise. Seeding accurate per-item, per-location opening stock — with lot detail where batches apply — is what makes day-one reports correct and everything after traceable.
Does a physical count change stock directly?
No — and this is deliberate. A physical stock take records the variance between the system (book) quantity and the counted (physical) quantity, but does not touch the balance. Reconciliation is a separate step: an adjustment document posts the increase or decrease, writing its own ledger entry. Separating counting from correcting preserves the audit trail — you can always see what was counted, what was adjusted, and by whom.
How often should stock be counted?
Most operations combine an annual or quarterly full count with perpetual (cycle) counting through the year — counting a subset of items on a rotating schedule without stopping the store. ABC analysis sets the rotation: high-value A items are counted most frequently, B items less often, and C items least. Inventory software supports annual, quarterly and perpetual count types on the same variance-then-adjust flow.
Where do reports fit in the process?
Reports are the sixth step and the reason the cycle exists: they turn posted movements into decisions. The stock ledger explains any balance movement by movement; valuation prices stock item- and store-wise; ABC classification focuses effort; reorder alerts flag items at or below minimum; expiry dashboards list near-expiry lots; and non-moving analysis surfaces frozen cash. Their accuracy depends entirely on the discipline of steps 2 to 5.
