Billing & inventory for electrical shops — simple GST POS + parts catalog

Small electrical and hardware retailers—an estimated 3.0 million shops globally in this target segment—still rely on paper invoices, pocket notebooks or Excel, which creates billing errors, inventory blindspots and tax compliance risk under GST regimes. Shopkeepers and managers, often non-technical and working on thin margins, spend hours reconciling stock versus sales, misprice parts, and struggle to produce GST‑compliant invoices during audits. A lightweight, mobile-first POS that combines GST e‑invoicing, straightforward inventory tracking and a curated parts catalog for electrical components could reduce billing time, shrink stockouts and make compliance routine. Practical features would include offline-first operation, one‑tap e‑invoice generation, OCR/LLM‑assisted entry from paper invoices and a searchable SKU catalog with images and distributor pricing to speed quoting and ordering. The timing is attractive: the addressable market is roughly $3.6B (3.0M shops × $1.2K ACV), SMB digitization is accelerating, and tax mandates plus affordable AI components lower both demand- and supply-side friction. Competition is medium—general POS vendors and local accounting software exist—but few products combine a vertical parts catalog, distributor integrations and low‑touch onboarding for non‑technical users; the main challenges will be keeping SKU and pricing data current across fragmented suppliers and acquiring price‑sensitive customers cost‑effectively, which makes distributor partnerships and clear, immediate ROI messaging essential if you decide to pursue it.
