SiMS Next — Store Management Suite (Rebuild)

A ground-up rebuild of SiMS Store Software: GST-compliant retail management for India — inventory, POS billing, purchases, and accounting — for everything from a single-counter kirana shop to multi-outlet supermarket chains.

Why the rebuild: the current product runs on Oracle Forms & Reports (hard to maintain, buggy, no path to cloud/multi-store), and the market is moving. Same customers, much better product.

North star: the fastest, easiest counter workflow in the market. The customer in line never waits because of the software, and purchase entry is never a burden.
