which industries is iSahulat built for?

manufacturing-first, BOMs, production batches, real cost-of-sale. also fits distribution, retail, and trading SMEs out of the box. the data model is generic; manufacturing-specific workflows light up when they're needed.

how does multi-tenancy work?

shared schema with company_id on every tenant table plus a tenantContext middleware that scopes every query. one platform- level super-admin can move between companies; nobody else can.

how accurate is the gross-profit number?

it's accurate to the rupee once you start booking purchase expenses against products and completing manufacturing batches. each stock-in records its real unit cost; each sale pops the layer queue. the COGS report shows you what fraction of period cost-of-sales came from the cost-price fallback so you can see when accuracy improves.

yes, single Express app + PostgreSQL • 32 migrations • the scheduler runs on node-cron in self-hosted environments and on Vercel Cron in production. self-host is one container plus a managed Postgres (Neon, RDS, or any other).

FLAGS

--multi-tenant: Each client company's data is fully walled off, one company can never see another's records, even on shared infrastructure
--layered-cogs: Real cost-of-sale per unit sold (FIFO or Weighted Average), every stock-in records its unit cost, every stock-out pops the layer queue
--secure-by-default: JWT rotation, CSRF protection, rate-limit + lockout, XSS input sanitisation, prod refuses to start without strong signing keys
--csv-everywhere: Customers, products, invoices, orders, receipts, expenses, bank transactions, all importable from spreadsheets with multi-row line items
--mobile-responsive: Sidebar collapses to a hamburger drawer • forms stack vertically • tables scroll sideways instead of squishing columns
--scheduler-ready: Five nightly jobs run on their own, overdue marking, recurring invoices, recurring expenses, trial expiry, token cleanup
