I'm looking for a word designating the main software of a company. I know the term line of business application, but I never heard anyone say "this is our line of business application", only "this is a line of business application."

I'm looking for the term designating the class of software applications that are the only ones to be at the heart of a company. A CRM is in this idea, since we often say "this our CRM software"; however, the software I'm trying to qualify goes beyond customer relationship management as it also takes care of the daily operations.

Any ideas?

  • Which of these three definitions for LOB are you using? Specifically, are you asking about 3rd-party s/w that's vital to the operation of a company, the main application sold by a s/w house, or the general type of s/w they sell? – FumbleFingers May 6 '15 at 15:36
  • @FumbleFingers Thanks a lot for your interest, I am using the 2nd definition. I'm talking about in-house software that is vital to the operation of a company. I've been thinking about it and I'm keen on going with "Operations Management s/w" what do you think ? – tobiak777 May 6 '15 at 15:42

    I think most companies would normally use "the same" software for, say, the sales ledger, purchase ledger, stock control, etc. But they might use a completely different supplier for their payroll & personnel records, so I don't really think many companies would need a name for "the" software they use, because they probably use several different systems (all of which might be considered "vital"). For the main product sold by a software house, I'd use flagship application. – FumbleFingers May 6 '15 at 16:06
  • I regularly use the phrase "our line of business software" to describe the core software used by our company. – Nick2253 May 6 '15 at 16:13
  • Are you thinking of ERP software? (See en.wikipedia.org/wiki/Enterprise_resource_planning for details) – Hellion May 6 '15 at 16:31

Enterprise Resource Planning software (ERP for short) is a set of integrated modules that allow you to control many, most, or all aspects of your business from a single package: financials (General Ledger, Accounts Payable, Accounts Receivable), order processing, purchasing, manufacturing, inventory management, time & attendance, payroll, etc.

Most companies run only one such system1, unless they are dealing with an acquisition or merger; although it is certainly common to run an ERP system, but have elements that could be managed by that system run instead on some other software (for instance, many companies will have a separate payroll system, even if their ERP software has a payroll module available).

1: (Or they are trying to consolidate down to one system, or at least they wish they were running only one.)

  • Of course, "ERP" has a mildly unfortunate connotation. – Hot Licks May 6 '15 at 20:46
