Electrical and electronics shop POS

Electrical shop management software: test stock, serials and repairs

Posnic Community Edition is free and open source for a controlled electrical-retail pilot. The current evidence supports quantity-based item, supplier, purchase, sale, return and stock paths. It does not prove unit serial or IMEI tracking, warranty claims or repair job cards, so this page shows exactly what to test and where another system is still needed.

Evidence and review scope

Evidence reviewed 2026-08-17. Pinned item-model, API and hardware-document review; one synthetic local Windows sale; focused retail, billing, import and hardware-protocol source tests; and official GS1, FTC and PCI SSC guidance.

Stable release: v1.3.0. No complete electrical or electronics shop day, serialized-device flow, warranty claim, repair job, physical barcode scan, physical receipt or payment-terminal transaction was executed.

How Posnic researches and corrects product content

One shop can contain four different systems

Quantity stock

Switches, lamps, cable, plugs and accessories can often use product-level SKU or barcode plus quantity, supplier, cost, price, tax and stock movement. This is the strongest current Posnic fit.

Serialized devices

Phones, computers, appliances and other unique units may need one immutable serial or IMEI from receiving through sale, return and replacement. The reviewed Posnic item model has no dedicated unit-serial field.

Warranty and repair

Warranty eligibility and repair custody need records beyond a final invoice. No dedicated claim or repair job-card lifecycle was found in the reviewed v1.3.0 models, routes and controllers.

Match the software to the record

Electrical and electronics shop workflows that should not be collapsed into one invoice.
Workflow	Record needed	Current Posnic boundary	Safe decision
Product catalogue	Name, SKU or barcode, category, supplier, price, tax and quantity.	Dedicated fields exist in the pinned item model.	Use representative products and verify search, tax and duplicate handling.
Supplier purchase	Supplier reference, quantity, cost, receipt exceptions and stock posting.	Receiving and purchase-return routes are documented; no complete shop run was executed.	Reconcile a mixed receipt and return before live use.
Retail sale	Item, tax, discount, payment state, receipt, user and stock result.	One synthetic local cash sale and focused receipt tests passed.	Run normal and exception sales on the exact counter.
Sales return	Original sale, reason, authorization, money movement and stock disposition.	Sales-return routes are documented, not accepted for a unique device.	Test sellable, damaged and wrong-unit returns separately.
Unit serial or IMEI	One unique identifier linked to each physical unit and every movement.	No dedicated accepted field or lifecycle was found.	Keep a separate controlled register until a release passes end-to-end acceptance.
Warranty claim	Terms, sale, unit identity, eligibility, custody, result and replacement.	No dedicated warranty-claim workflow was found.	Use a governed claim process approved for the shop's jurisdiction.
Repair job	Intake, condition, diagnosis, estimate, approval, parts, payment, status and delivery.	No dedicated repair job-card lifecycle was found.	Use a purpose-built service system until the complete flow is accepted.

Area	Observed evidence	Boundary
Item model	Product barcode, SKU, category, supplier, branch, quantities, costs, prices, tax, HSN and inventory flags are present.	No dedicated unit serial, IMEI, warranty or repair-job field was found.
Retail source review	Pinned documentation covers sales, purchases, returns, stock movement, barcode input and low-stock paths; 57 vertical-supporting tests passed.	No complete retail or electronics-shop day was executed.
Local sale	Synthetic cash sale S-O2MA-000001 was stored and reopened on Windows while external hosts were blocked inside Electron.	Not a system-wide disconnection, serialized sale, physical print or payment-terminal test.
Receipts and reports	Thirty-seven focused receipt, report, local-asset and sales call-path tests passed.	No physical receipt or complete counter shift was run.
Product import	Seven shipped CSV templates passed six structural and sample-data tests.	The import was not executed through the user interface.
Scanner and print paths	The pinned matrix documents keyboard-wedge scanning and 35 receipt, report and scale protocol tests passed.	No physical scanner, printer, drawer, scale, display or payment terminal was connected.
Returns	Pinned API documentation lists sales-return and purchase-return routes.	No serialized return, exchange, warranty claim or supplier reimbursement was accepted.
Repair workflow	Targeted model, route and controller review found no dedicated repair lifecycle.	Intake, custody, estimate, approval, technician, parts, advance, status and delivery remain unproved.

Prepare a controlled electrical-retail pilot

List every product class and mark it as quantity stock, serialized stock, service charge, repair part or customer-owned property.
Create clean names, SKU or GTIN, barcode, category, supplier, cost, selling price, tax and opening quantity for representative items.
Do not use one shared product barcode as a unique device serial. Define a separate unit identifier and system when traceability is required.
Receive a supplier order with partial, damaged and returned lines, then match stock and supplier evidence.
Run normal sale, discount, cancellation, failed payment, return and exchange scenarios on the exact computer and receipt format.
Connect one real scanner in keyboard-wedge mode and test good, duplicate, unknown, damaged and 2D labels before buying more devices.
Set off-machine backup and complete a restore into a disposable environment before trusting the counter.
Keep warranty claims and repair jobs outside Posnic until their full identity, custody, status, payment and closure workflows are accepted.

Minimum evidence before go-live

A physical count matches quantity stock for the pilot catalogue.
A supplier receipt and purchase return reconcile to stock and documents.
A sale, cancellation, refund and exchange retain original references and named users.
The receipt and payment state remain truthful when a printer or payment provider fails.
Every required unique unit can be searched from receiving through sale and return without an editable free-text shortcut.
Warranty terms and claim handling have been approved for the actual jurisdiction and warrantor.
Customer-owned repair devices have a separate custody and delivery record.
The backup, restore, export and owner sign-off are retained with the tested release version.

Product evidence to inspect

Posnic purchase entry screen with supplier, quantities, tax and receiving state — **Purchase entry**This screen is relevant to supplier receiving. It does not demonstrate unique serial capture or a completed receiving drill.

Posnic inventory log showing opening stock, stock count and closing stock — **Quantity stock history**The screen shows quantity movement, not one immutable lifecycle per serial number or IMEI.

Posnic v1.3.0 synthetic cash sale used in local runtime evidence — **One local sale result**The synthetic sale was stored and reopened. It was not a device-serial, warranty, repair, scanner, printer or payment-terminal test.

Questions buyers ask

Is Posnic electrical shop management software free?

Posnic Community Edition v1.3.0 has a zero software price for local use and public AGPL-3.0-only source. Hardware, setup, support, backups, updates and downtime can still create costs.

Can an electrical shop use Posnic for stock and billing?

The current evidence supports a controlled pilot for quantity-based items, suppliers, purchases, sales, returns, stock movement and reports. A complete electrical-shop day and physical hardware setup still need local acceptance.

Does Posnic track serial numbers or IMEI per device?

Not as a dedicated accepted v1.3.0 workflow. Product barcode and SKU fields exist, but the reviewed item model has no dedicated unique-unit serial or IMEI field.

Can Posnic manage electronics warranty claims?

No dedicated warranty-claim lifecycle was found in the reviewed source. A sales return alone does not cover terms, eligibility, serial identity, custody, repair or replacement evidence.

Can Posnic manage electronics repair jobs?

No dedicated repair job-card lifecycle was found in the reviewed v1.3.0 models, routes and controllers. Use a purpose-built service record until intake through delivery passes acceptance.

Will a barcode scanner work with Posnic?

The pinned hardware matrix describes keyboard-wedge scanner input, but this review connected no physical scanner. Test the exact scanner mode and representative labels before purchasing multiple units.

Where should I download electrical shop POS safely?

Use the official Posnic download page or the Posnic GitHub release and verify the published checksum. Avoid cracked, repacked or mirror installers for software that handles business records.
