Know what you hold, where it sits and what it cost, with every movement recorded so shrinkage and stockouts become visible early.
Inventory Management Software Development: what the work involves
Stock problems are expensive in two opposite ways: cash locked in slow items, and sales lost because a fast item ran out. Businesses that count by eye and record by memory learn about both only at the annual stocktake, when the damage is already done. Inventory software turns every receipt, sale, transfer and adjustment into a ledger entry, so the on-hand quantity is a result of recorded movements rather than a guess.
DevKey builds the item master with units of measure, variants, barcodes and optional batch or expiry tracking, then layers movements on top. Multiple stores or godowns are separate locations with inter-location transfers that stay in transit until received. For shops with weak internet we ship an offline-first Electron app on SQLite that syncs to the central PostgreSQL database, with conflict handling, and barcode scanners work as ordinary keyboard input.
Core features
Item master with variants
Size, colour and pack variants, multiple units with conversion factors, and barcode assignment live under one parent item.
Stock movements ledger
Purchases, sales, returns, transfers, damages and adjustments each create a dated entry with user and reason attached.
Multi-location stock
Quantities are held per godown or branch, with transfer documents that show what is in transit and who has not yet acknowledged receipt.
Batch and expiry control
Lots are received with expiry dates, issued first-expiry-first-out, and flagged on a near-expiry report before they become a write-off.
Reorder and min-max alerts
Each item gets a reorder level and suggested quantity based on recent consumption, so purchasing starts from data.
Stocktake and valuation
Cycle counts are entered against system quantity, differences are posted as approved adjustments, and valuation can use average or FIFO cost.
What we get right before launch
Costing method choice
Average cost, FIFO and latest-purchase give different profit figures. Decide with your accountant early, since changing the method later means revaluing history.
Negative stock policy
Staff often sell before purchase entries are posted. We let you choose between blocking such sales or allowing them with a flag, because both have consequences for costing.
Opening stock accuracy
The system is only as right as the first count. We plan a clean physical count at go-live, with the shop frozen briefly, rather than importing a doubtful spreadsheet.

Common questions, answered
Will it work if our internet goes down?
The offline-first desktop version keeps selling and receiving stock from a local database and syncs when the connection returns. We define in advance how simultaneous edits to the same item are resolved so quantities remain consistent.
Can we use barcode scanners and label printers?
Yes. Standard USB scanners work as keyboard input, and we generate and print item labels with barcodes on common label printers. Please share your hardware model so we confirm drivers before development.
How do we move from Excel stock sheets?
We structure the item list, assign codes and units, and load opening quantities after a physical count. The old sheet is retained read-only for reference until your first full month reconciles.
Does it connect to sales and accounting?
Stock is typically one module of a wider system, posting cost of goods automatically. If you already use accounting software, we can export purchase and sales vouchers or integrate by API.
