School ERP vs SIS vs LMS: what's the difference?

5 min read · Updated 14 November 2026 · By the KlassMint team

Short answerAn SIS (or MIS) is the central record of students and their school data. A school ERP includes the SIS and adds the running of the school, such as admissions, fees, timetable, transport and communication. An LMS is for teaching and learning content, such as online courses, lessons and quizzes. Most schools need an ERP or SIS first; an LMS is optional and can sit alongside it.

School software comes with a lot of three-letter names. They overlap, vendors use them loosely, and buyers end up comparing products that do different jobs. Here is what each term usually means.

SIS: student information system

An SIS is the central record of students: personal details, family contacts, enrolment, class and section, attendance, grades and often documents. Everything else in the school depends on this data being right.

MIS (management information system) is the name many UK and international schools use for the same idea, usually covering staff as well as pupils.

School ERP: the whole school’s operations

ERP stands for enterprise resource planning. A school ERP includes an SIS and adds the running of the school:

  • Admissions and enquiries
  • Fees, online payments, receipts and refunds
  • Timetable, homework, exams and grades
  • Notices, messages and parent communication
  • Branches, transport, leave and reports

School management system (SMS), school administration software, campus management software and education ERP usually mean the same thing.

LMS: learning management system

An LMS is about teaching and learning content: online courses, lesson materials, videos, quizzes and assignments that students work through. Examples include platforms schools use for online classes and course content.

An LMS usually does not handle fees, admissions or transport, and it often relies on an SIS for the list of students and classes.

Side by side

SIS / MIS School ERP LMS
Student and family records Yes Yes Basic
Attendance Usually Yes Sometimes
Admissions and enquiries Sometimes Yes No
Fees and online payments Rarely Yes No
Timetable Sometimes Yes No
Homework and grades Grades Yes Yes
Online courses and lessons No Rarely Yes
Parent communication Sometimes Yes Sometimes

Which one does your school need?

  • If you run on registers and spreadsheets: start with a school ERP. It gives you clean records and handles the daily office work.
  • If you already have good records but fees and communication are painful: look for an ERP that covers those modules.
  • If you teach online courses or need lesson content: add an LMS alongside your ERP or SIS.
