Invoyes

Built a multi-tenant SaaS that lets restaurant and retail owners run their entire shop from one place — point of sale, invoicing, inventory, suppliers, staff and live analytics. Pricing is plan-based with a 7-day free trial and the system scales from a single counter to a chain of stores.

The challenge

Existing POS tools either targeted enterprise chains or were brittle single-shop tools. We needed a system that felt native to a small restaurant on day one but could grow into a multi-store, multi-staff operation without rewriting any of the data model.

How I approached it

• →Architecture: Designed a tenant-per-organization schema in PostgreSQL with store-scoped rows so a single account can spin up multiple branches without data leakage.
• →POS engine: Built on Laravel with a Next.js front-end — order, payment, refund and inventory reservations are wrapped in transactional service classes to keep stock truthful under concurrency.
• →Offline invoicing: Shipped offline-tolerant invoicing with optimistic UI so cashiers never wait on the network during peak hours; conflicts reconcile on reconnect.
• →Analytics layer: Created materialised views for daily/weekly/monthly summaries to keep dashboards fast even for chains with high transaction volume.
