Inventory is the part of the system that everything else touches. Sales need to know what's available. Production needs to know what to consume. Purchasing needs to know what to replenish. Finance needs accurate stock valuations. When the warehouse is a mess — duplicate product records, unknown stock locations, batches that can't be traced — it breaks all of these simultaneously.

Here's how 1C:Drive organizes inventory, and what you need to set up to make it useful.

How Stock is Tracked: The Accounting Dimensions

Every stock balance in 1C:Drive is tracked across a set of dimensions. Understanding these helps you understand what reports you can run and what level of detail is possible.

At the top level: company (which legal entity owns the stock) and ownership (your own goods vs. goods held on behalf of a third party — a consignor, or a subcontractor who sent materials for processing).

Then: warehouse, storage bin (the specific location within a warehouse), product, variant (size, color, or other combination of attributes), batch, serial number, and order (if the product is reserved for a specific order rather than available as free stock).

This structure means you can answer questions like: "how many blue XL t-shirts do we have in Shelf B-4 of Warehouse 2, expiring before March 31, reserved for Sales Order 1042?" That's the level of precision the system supports — but you only need to use the dimensions that make sense for your business.

Warehouses and Storage Bins

A warehouse in 1C:Drive is either a standard warehouse (handles both wholesale and retail) or a point of sale (retail only, with two subtypes depending on whether you're running an automated cashier or not).

Within a warehouse, you can define storage bins — specific shelf, rack, or zone locations. This is optional, but useful once your warehouse reaches a size where "it's somewhere in Warehouse 2" isn't good enough. With bins defined, goods receipts and transfers can specify exact locations, and picking lists can guide workers to the right spot.

Products: Variants, Batches, and Serial Numbers

These three features handle product diversity at different granularities.

Variants are for products that come in combinations of attributes — a T-shirt in sizes S/M/L and colors blue/green/orange/black. Instead of creating 12 separate products, you create one product with two attribute dimensions. The system stores stock, purchases, and sales for each variant combination. When entering a sales order, you get a matrix view that lets you specify quantities for multiple variants at once.

Batches are for tracking a quantity of goods as a unit with shared attributes — typically expiration date and manufacturing date. When you receive 100 units of a product with an expiry of March 20, that's one batch. When you ship goods, the system can automatically apply FEFO (First Expired, First Out) logic, filling your sales documents with the batch closest to expiry first.

Serial numbers track individual units. Each serial number has its own history — received on this date, sold to this customer, under warranty until this date. For businesses providing after-sales service, knowing the service history of a specific unit requires serial number tracking.

These three features can be combined: a serialized product that also uses batch tracking, or product variants that also have batch numbers. Use what fits your product and compliance requirements — serial numbers add overhead and aren't worth it unless you need unit-level traceability.

Reservations: Free Stock vs. Reserved Stock

When stock is reserved for an order, it's no longer available to anyone else. This sounds obvious, but without a proper reservation system, two salespeople can commit the same stock to two different customers.

1C:Drive separates stock into free stock and reserved stock by order. Three reservation scenarios are supported:

• Reserving goods already in the warehouse

• Reserving goods that need to be purchased (backordered reservation)

• Reserving goods that need to be manufactured or assembled

If the full document chain is created correctly (sales order → production order → purchase order, each based on the previous), reservation flows automatically. If you need to manage reservations manually — because you're combining goods from multiple sources — there's a dedicated inventory reservation document.

Transferring Goods

Moving goods within your operation uses two document types.

Inventory transfer moves goods from one storage location to another (different warehouses, or a warehouse to a department). There's a two-step option: a transfer order creates a planned movement, and the inventory transfer document records the actual movement when it happens.

Intra-warehouse transfer moves goods between storage bins within the same warehouse — reorganizing shelf locations, for example.

There are also specific transfer operations for writing off materials to production (charge to expenses), issuing equipment to a department, and returning equipment from a department.

Physical Inventory: Counting What's Actually There

At some point, you need to count what you have and reconcile it against what the system says. The physical inventory process in 1C:Drive works like this:

1. Create a physical inventory document, which pulls the current accounting quantities for your selected warehouse (and bin, if applicable)

2. Print the count sheets and give them to your team

3. Enter actual counts when staff returns the sheets

4. The system calculates discrepancies

The physical inventory document itself doesn't post any accounting entries. Discrepancies are resolved through two separate documents: inventory increase (enter missing goods at specified cost) and inventory write-off (remove surplus or damaged goods at current cost).

How Warehouse Transactions Connect to Other Modules

Warehouse management doesn't exist in isolation — here's how it connects to the rest of the system.

Purchases: Goods arrive via goods receipt or supplier invoice (depending on accounting policy). Landed costs and customs declarations add to the inventory cost of received goods. Credit limits and order reservations are checked when receiving.

Sales: Goods leave via sales invoice or goods issue. Stock balances, batch availability, reservations, and credit limits are all checked at shipment. FIFO cost calculation runs either in the background during the month or at month-end closing.

Production: Materials are consumed through work-in-progress documents. Semi-finished products move between production stages. Finished goods are received into the warehouse through production documents. All costs — materials, labor, overhead — are allocated to the finished product at month-end.

Valuation methods: The system supports weighted average cost and FIFO. FIFO requires a background job for in-period calculations and a month-end closing run for final accuracy. The stock statement (FIFO) report lets you verify cost assignments throughout.

Ownership: Your Goods vs. Third-Party Goods

Not everything in your warehouse belongs to you. 1C:Drive tracks ownership as a dimension on all stock.

Materials sent by a subcontractor for processing are in your warehouse but are their property. Goods received for commission sale (consignment) belong to the consignor. The system keeps these separate from your own inventory in both the stock records and the reports, so your balance sheet doesn't accidentally include stock you don't own.

What You Can Report On

The inventory module has 15+ standard reports. The core ones: available stock (what's free vs. reserved), stock statement (full movement history for a period), goods in transit, and stock received from third parties. All support drill-down to source documents.
