ERP meaning: what does ERP stand for?

ERP stands for Enterprise Resource Planning. Each word tells you part of the meaning:

  • Enterprise: the whole business, not one department.
  • Resource: what the business runs on: material, machines, money and people.
  • Planning: deciding how to use those resources, and then tracking what actually happened.

So the meaning of ERP, in plain words, is software that plans and records everything a business does, in one place. When people say "ERP", "ERP system" or "ERP software" they mean the same thing.

ERP full form: Enterprise Resource Planning.

What is an ERP system?

An ERP system is a set of connected modules (sales, purchase, inventory, production, accounting, HR and so on) that share one database. A record entered once is visible everywhere it is needed.

Without ERP, most growing businesses run on a mix of tools: Tally for accounts, Excel for stock and production, WhatsApp for orders, and a separate payroll tool. Each tool is fine on its own. The trouble is between them. Someone has to copy data from one to the other, the numbers drift apart, and nobody is sure which sheet is right.

ERP removes those gaps. The salesperson, the store keeper, the plant manager and the accountant all look at the same order, the same stock and the same invoice.

How does an ERP system work? A worked example

Follow one order through a small manufacturer that makes steel brackets:

  1. Sales: a customer orders 5,000 brackets. The salesperson creates a sales order in the ERP.
  2. Inventory: the system checks finished stock (1,200 in hand) and shows a shortfall of 3,800.
  3. Planning: it uses the bill of materials to work out the steel sheet, bolts and paint needed for 3,800 pieces, and compares that with raw material stock.
  4. Purchase: short material becomes a purchase request, then a purchase order to the vendor.
  5. Production: a work order is released to the shopfloor once material is in. Output and scrap are recorded against it.
  6. Dispatch and billing: finished goods are packed, a GST invoice and e-way bill are raised, and stock reduces automatically.
  7. Accounts: the sale, the purchase and the receivable post to the ledgers. The owner sees margin on the order without waiting for month end.

Nobody re-typed the order. That single flow is what an ERP system does.

What is ERP software, and how is it different from accounting software?

Accounting software such as Tally records the financial result of what happened: invoices, payments, ledgers and GST. ERP software also runs the work that creates those entries: the order, the stock, the purchase and the production.

Many businesses keep Tally and add ERP around it. DotOne has its own accounting, and can also sync to Tally if your CA prefers it.

Types of ERP

  • Cloud ERP: runs on the vendor's servers and opens in a browser or mobile app. Paid monthly, no servers to manage. See what is cloud ERP.
  • On-premise ERP: installed on your own servers. You buy licences and look after the hardware, backups and upgrades.
  • Industry ERP: built or configured for one industry, such as manufacturing ERP, with the workflows that industry needs.
  • Small business ERP: a lighter, faster-to-start setup. See ERP for small business.

Who needs ERP? Signs it is time

  • You cannot tell live stock without calling the store.
  • Orders are promised without knowing whether material or capacity is free.
  • The same data is typed into Excel, Tally and WhatsApp.
  • Month-end closing takes days, and profit by product or customer is a guess.
  • You have opened a second plant, warehouse or branch, and visibility has dropped.

If three or more of these are true, an ERP will usually pay for itself in saved time and less excess stock. Our guide on how to choose an ERP walks through the next steps, and ERP implementation covers going live.

Is Tally an ERP?

Tally is mainly accounting and inventory software. It does not cover production planning, CRM or HR in depth, which is why many businesses run an ERP alongside it or replace it.
