Back-office software is the software a company uses to run its own business away from its customers: taking orders, keeping stock, buying from suppliers, paying bills and keeping the accounts. Customers never see it. Staff in sales, the warehouse, purchasing and finance use it every day. It is also called enterprise software or business software.
Consider a fan maker in Coimbatore. A dealer orders 200 ceiling fans. The sales team records the order. The warehouse checks whether 200 fans are in stock. The purchasing team orders more motors from a supplier. Finance raises the invoice, with GST, and later records the dealer's payment. All four teams must read the same numbers. If they do not, the company may ship fans it does not have, or bill for fans it never sent.
The software for this work falls into four groups.
The first group is the ERP and accounting systems. They hold the company's system of record: the one database in which orders, stock, purchases, invoices and accounts are kept and agreed. A large company runs an enterprise resource planning (ERP) suite. A small shop keeps its books in small business accounting software on a phone.
The second group is enterprise integration. A mid-sized company runs a few hundred applications, such as the ERP, the CRM in which the sales team tracks customers, and the warehouse system. When the dealer's order changes, every one of them must receive the change. An integration platform copies each changed record between the applications as it happens. Older tools move files and run batch jobs overnight, such as the payment file that must reach the bank by midnight.
The third group is business process automation. Between the systems sit people who copy, check and approve. For example, an employee in the accounts team types each supplier invoice into the ERP. A software robot can do that typing. Process mining shows where the work gets stuck. And AI agents are now sold to do the desk work of a whole role.
The fourth group is document management. Much of a company's information arrives as documents: invoices as PDFs, scanned forms and long contracts. Intelligent document processing reads them into fields. Enterprise content management keeps them for as long as the rules require. An electronic signature replaces the courier when a contract is signed.
Most of this software is now rented over the internet as software as a service (SaaS), instead of being installed on the company's own servers. India builds a large part of it. Many of the world's ERP, integration and automation companies run large engineering centres in Bengaluru, Hyderabad, Pune and Chennai, and several Indian companies sell their own products around the world.
