Coupons for Laravel

Create, validate and redeem discount coupons in Laravel: fixed, percentage (optionally capped) and free-shipping discounts with currency locks, minimum spends, activation windows and global or per-customer usage limits. Redemption is atomic, and every amount is an exact money-for-laravel Money.

Installation

Requires PHP 8.4 (ext-bcmath), Laravel 12 or 13, and MySQL or PostgreSQL.

composer require roundly-consulting/coupons-for-laravel
php artisan vendor:publish --tag="coupons-migrations"
php artisan migrate

If the models that redeem coupons have UUID/ULID keys, set COUPONS_KEY_TYPE before migrating.

Usage

Create a coupon through the facade. New coupons start inactive, so activate it:

use RoundlyConsulting\Coupons\Enums\DiscountType;
use RoundlyConsulting\Coupons\Facades\Coupons;

$coupon = Coupons::generate(DiscountType::Percentage, value: 2000, code: 'SUMMER', maxUsage: 100); // 20 % off
$coupon->activate()->save();

At checkout, check it, preview the discount and redeem it against the cart total:

use RoundlyConsulting\Money\Money;

$cart = Money::ofMinor(5000, 'EUR');                       // €50.00

Coupons::code('SUMMER')->check($cart, $user);              // null, or why not: Expired, AtMaxUsage, …
Coupons::code('SUMMER')->preview($cart);                   // 10.00 EUR, without redeeming

$result = Coupons::code('SUMMER')->redeem($cart, $user);   // atomic; throws a CouponException if refused

$result->discount;                                         // 10.00 EUR
$result->total;                                            // 40.00 EUR
