Started a small business selling products online only using opencart. Later opened physical shop and used multi-store feature in opencart as a point of sale, while still running the online side as well. As business grew, needed warehouse and second physical shop.

The biggest issue we faced was stock management/stockout issues. Available ones like dynnamics/topshelf/sap were very expensive for us, so I developed a web based inventory management tool in php/aurelia. It could do multi-warehouse/shelf level inventory. Shelfs are barcode labelled and its all paper free. Also added point-of-sale for shop use, catalog management, multi-pricelist/multi-currency (retail/wholesale) etc. It still runs the business as of today.

Now writing new version from scratch using nestjs/svelte with multi-tenantancy (so that others can sell on it).
