Stock that reorders before it runs out.

One live stock ledger across every godown. It knows how fast each item sells, warns you days before a stockout and drafts the purchase order for you.

The problem

“We run out of best-sellers — and over-stock everything else.”

What is inventory and purchase ERP software?

Inventory and purchase ERP software keeps one live stock ledger across all your godowns, works out how many days each item will last at today’s sales speed and suggests what to buy before it runs out. It groups the suggestions by supplier into purchase orders and tracks them until the goods arrive.

Built around your workflow: this demo is a starting point — screens, fields, rules and integrations are made to fit your business.

Counted on the demo: suggested quantities are grouped by supplier and sent as purchase orders with one action.

01 · The problem

What problem does it solve?

Picture a distributor supplying a few hundred retailers from three godowns. Stock lives in a spreadsheet per godown, updated at night. The owner decides what to buy from memory and phone calls.

The result is the classic squeeze: best-sellers run out mid-week while slow items sit for months, holding cash that could have bought the fast movers.

  • Lost sales

    Retailers buy elsewhere when a best-seller is out.

  • Locked cash

    Money sits in stock nobody is ordering.

  • Hours of reconciling

    Three spreadsheets never quite agree.

  • Gut-feel buying

    No single answer to “what should we buy today?”

02 · The solution

How does Stock & Purchase ERP fix it?

  1. 01

    One ledger, many godowns

    Every sale, goods receipt (GRN) and transfer posts to one stock ledger, so stock is live for every godown and in total.

  2. 02

    Days of cover, not just quantity

    Stock ÷ average daily sales tells you how many days each item will last. Below the supplier’s lead time plus a safety buffer, it’s time to reorder.

  3. 03

    Suggested quantities

    The system proposes how much to buy to reach a target cover, and checks whether another godown can transfer stock first.

  4. 04

    Purchase orders in one click

    Suggestions are grouped by supplier into a purchase order, sent as a PDF on WhatsApp or email and tracked until the goods arrive.

  • PO cycle time

    From reorder alert to goods received.

FAQ

Stock & Purchase ERP FAQ

All questions →
What is inventory and purchase ERP software?

Inventory and purchase ERP software keeps one live stock ledger across all your godowns, works out how many days each item will last at today’s sales speed and suggests what to buy before it runs out. It groups the suggestions by supplier into purchase orders and tracks them until the goods arrive.

What is days of cover in inventory management?

Days of cover is current stock divided by average daily sales — how many days the stock will last at today’s speed. When it falls below the supplier’s lead time plus a safety buffer, it is time to reorder.

Can it work with Tally?

Yes. Sales and purchase vouchers can be imported from Tally or Busy so the stock ledger stays in step, and purchase orders can be posted back.

Does it handle several godowns or warehouses?

Yes. Every sale, receipt and transfer posts to one ledger, so you see stock per godown and in total — and the system checks whether another godown can transfer stock before you buy.

Can godown staff use it on a phone?

Yes. Goods receipts, transfers and stock counts can be done from a phone, with barcode or QR scanning if you label your stock.

How long does it take to build?

A first version with stock, purchase orders and alerts usually takes 8–12 weeks; integrations and reports are then added in stages without stopping your work.
