10 Best Laravel POS (Cashier) Source Codes in 2026

You need a point-of-sale app for your own shop or for a client, and building one from scratch would take months. The problem is that dozens of Laravel POS projects online have nearly identical demos. How do you tell the ones ready for real retail from the ones that only look good in screenshots?

Instead of a subjective ranking that goes stale in a few months, this guide gives you ten criteria you can apply to any POS source code in 2026. Each comes with the technical reason and a way to check it, plus a table design, local setup steps, and the limitations you should expect.

What a POS App Solves

A POS replaces handwritten receipts and manual tallies. Sales are recorded automatically, stock drops with every sale, and profit reports are available without recounting. A web-based Laravel POS also makes multi-location access and payment integration easier. New to the concept? Start with what a POS system is and how it works.

10 Criteria for a Production-Ready Laravel POS

1. Complete product, stock, and variant management. Each size or flavor needs its own stock. In the demo, add a variant, sell it, and confirm only that variant's stock drops.
2. Stock movement history. A single stock number with no history makes audits painful. Good code logs every sale, purchase, and adjustment in a separate table.
3. Sales and profit reports filterable by period. Profit is accurate only if cost price is stored at the time of sale.
4. Multiple users with roles. At minimum cashier, manager, and owner. Cashiers should not delete sales or change prices.
5. Receipt printing with thermal printer support. Ask which paper widths are supported (58 mm or 80 mm) and whether printing goes through the browser dialog or a helper app.
6. Discount management. Line and order discounts should be stored separately so reports show revenue given away in promotions.
7. Digital payment methods. Card and mobile wallet payments should at least be selectable tender types so cash and non-cash totals reconcile separately.
8. Customer membership. Registered customers support loyalty programs and show who returns most often.
9. Multi-location readiness. If branches are planned, stock and sales tables need a location column from day one. Adding it later is much harder.
10. Documentation and regular updates. An install guide, .env.example, and version history show the project is maintained. An old Laravel release with no upgrade path is technical debt.

The Table Design to Look For

Criteria 2 and 3 are easiest to verify in the migrations folder:

CREATE TABLE sales (
  id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  outlet_id BIGINT UNSIGNED NOT NULL,
  cashier_id BIGINT UNSIGNED NOT NULL,
  invoice_no VARCHAR(30) NOT NULL UNIQUE,
  payment_method VARCHAR(20) NOT NULL,
  discount DECIMAL(12,2) NOT NULL DEFAULT 0,
  total DECIMAL(12,2) NOT NULL,
  created_at TIMESTAMP NULL,
  INDEX (outlet_id, created_at)
);

CREATE TABLE sale_items (
  id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  sale_id BIGINT UNSIGNED NOT NULL,
  variant_id BIGINT UNSIGNED NOT NULL,
  qty INT NOT NULL,
  price DECIMAL(12,2) NOT NULL,
  cost_price DECIMAL(12,2) NOT NULL
);

CREATE TABLE stock_movements (
  id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  outlet_id BIGINT UNSIGNED NOT NULL,
  variant_id BIGINT UNSIGNED NOT NULL,
  type ENUM('sale','purchase','adjustment','transfer') NOT NULL,
  qty INT NOT NULL,
  reference VARCHAR(40) NULL,
  created_at TIMESTAMP NULL,
  INDEX (variant_id, outlet_id)
);

Note cost_price on sale_items. Without it, last month's profit changes every time a supplier raises prices. With it, a period profit report is a single query:

$grossProfit = SaleItem::query()
    ->join('sales', 'sales.id', '=', 'sale_items.sale_id')
    ->whereBetween('sales.created_at', [$from, $to])
    ->selectRaw('SUM(sale_items.qty * (sale_items.price - sale_items.cost_price)) AS gross_profit')
    ->value('gross_profit');

Test Stock Deduction With Two Cashiers

With two registers, two sales can grab the last unit in the same second. Careless code lets stock go negative. Look for stock deduction wrapped in a database transaction with row locking, roughly like this:

DB::transaction(function () use ($cart, $outletId) {
    foreach ($cart as $line) {
        $stock = Stock::where('variant_id', $line['variant_id'])
            ->where('outlet_id', $outletId)
            ->lockForUpdate()
            ->firstOrFail();

        if ($stock->qty < $line['qty']) {
            throw new RuntimeException('Insufficient stock');
        }

        $stock->decrement('qty', $line['qty']);
    }
    // save sales, sale_items and stock_movements here
});

If anything fails midway, the transaction rolls back every change and the data stays consistent.

Readiness Levels Compared

Running It Locally to Evaluate

1. Install PHP 8.2+, Composer, MySQL, and Node.js.
2. Extract the code and run composer install.
3. Copy .env.example to .env, set the database, run php artisan key:generate.
4. Run php artisan migrate --seed for sample data.
5. Run npm install && npm run build if there are frontend assets.
6. Log in as a cashier, ring up ten mixed sales with discounts, then log in as owner and check the report against your own math.

Step six is the most honest test. If the report does not match your paper totals, you want to know before the shop depends on it.

Customizing Safely

Commit the original to Git before changing anything. Add columns through new migrations rather than editing ones already run. Change receipt layout in Blade templates, not in transaction logic. For big changes such as adding multi-location support, plan a data migration and test on a copy of the database. See customizing source code without breaking it.

Common Selection Mistakes

• Judging by the UI alone. A UI can be reskinned in days; a flawed schema takes weeks to fix.
• Never testing receipts on real hardware. Browser printing often breaks margins and paper sizes.
• Ignoring the license. Confirm you may install it for clients or several stores before paying.

Pre-Purchase Checklist

• [ ] Cashier and admin demos are available
• [ ] Laravel and PHP versions are still supported
• [ ] Stock per variant with movement history
• [ ] Cost price stored on each sale item
• [ ] Separate cashier, manager, and owner roles
• [ ] Receipts tested on your paper width
• [ ] Install docs and .env.example included
• [ ] License terms and support scope in writing

Limitations

Basic installation needs little expertise, but customization requires Laravel knowledge. Direct integration with specific hardware such as scales is usually missing and must be built. You also own hosting, backups, and server security. For examples to test against these criteria, the GudangCode catalog lists a few Laravel POS projects.
