Sylius Bug Fix Service

Help for Sylius-based shops: checkout and cart errors, order state machines,
promotion and shipping rules, payment plugins, and customizations that break upgrades.

What this service covers

Shop, checkout, and cart flow debugging
Payments, refunds, and gateway integrations
Shipping and pickup resolution logic
Promotions, coupons, and pricing rules
Admin order and catalog management bugs

Common situations

Orders stuck in an unexpected state
