Aqua Core OS

Two ledgers, because water plants are owed money and bottles.

Know exactly who owes you cash and who is holding your bottles. Aqua Core OS runs a bottled-water plant end to end: customers, drivers, daily deliveries and the two balances that decide whether the plant is healthy. A group runs every plant from one login.

  • Unlimited customers and drivers per plant
  • Cash balance and bottle balance, kept separately
  • Opening balances carried in from your old book
  • A driver app that records deliveries with no signal

Inventorini

Cartons and loose pieces, counted the way a godown counts them.

Stop recounting cartons by hand. Stock is kept in the two units a godown actually deals in: full cartons and loose pieces. Open a carton and the pieces appear. Bill from either. Every bill shows what it earned, udhaar goes on each customer's own khata, and every shop gets a free storefront customers order from over WhatsApp.

  • Cartons and loose pieces tracked together
  • Profit shown on every bill
  • An udhaar khata for every customer, with WhatsApp reminders
  • A free storefront with WhatsApp ordering

Why we build products
We eat the same food
Every client platform we build uses the stack, the on-call rota and the release pipeline our own products run on.
Markets we know
Bottle balances, carton splits and a walima guest list are specific problems. Generic apps get the defaults wrong.
Support from the authors
The people who wrote the code answer the support line. That is true of client projects too.
