What is ERP software? ERP (enterprise resource planning) software is one system that runs a company's core operations, including people, sales, projects, assets and money, on a single shared set of records. This plain-English guide explains what an ERP suite includes, when a growing company needs one, and how to choose and price it well.
What is an ERP suite, in plain English?
An ERP suite is a set of business applications that share one database, one login and one set of permissions. Instead of HR, sales and accounting each keeping their own copy of an employee or customer, every application reads and updates the same record, so a change made once shows up everywhere.
Older ERP systems were large, expensive projects aimed at big manufacturers. Modern cloud ERP suites are built for companies with tens or hundreds of people, and you can start with the applications you need today. You can see how the pieces fit together on the PeopleParity applications page.
What does an ERP suite include?
Most ERP suites cover the same core areas: human resources and payroll, sales and customer management, recruitment, training, projects and tasks, company assets, invoicing and accounting, and documents. The value comes less from any single module than from the fact that they all share the same people, customers and permissions.
| Business area | What it handles | PeopleParity application |
|---|---|---|
| People | Payroll, leave, attendance, policies and offboarding | HRM |
| Hiring | Job postings, candidate pipeline, interview scheduling and offer approvals | ATS |
| Training | Course authoring, video, quizzes and bulk enrolment | Learning |
| Sales | Contacts, companies and a deal pipeline with follow-up tracking | CRM |
| Work | Kanban, list and Gantt views with recurring workflows | Task Manager |
| Equipment | Asset lifecycle, assignments, QR labels and warranty alerts | Asset Manager |
| Money | Multi-currency invoicing, tax handling and double-entry accounting | Finance |
| Paperwork | Templates with merge fields, approval routing and PDF output | Documents |
How is an ERP suite different from separate tools?
Separate tools each hold their own copy of your data, so the same employee or customer is typed in several times and the copies drift apart. An ERP suite keeps one record per person, customer and asset, with one login and one permission model, so reports agree and nobody reconciles spreadsheets at month end.
- Duplicate data entry: a new hire is added to HR, payroll, the project tool and the IT asset list separately.
- Access drift: when someone leaves, every tool needs its own offboarding, and one is usually missed.
- Reports that disagree: headcount in HR and in finance rarely match when they come from different systems.
- Stacked subscriptions: each tool is priced on its own, often with its own feature tiers.
In PeopleParity, for example, offboarding revokes Microsoft 365 access, and sign-in is removed automatically when an employee is marked as exited, because HR and access control share the same employee record.
When does a growing company need an ERP?
Many companies feel the need once they reach a few dozen people and spreadsheets and point tools stop keeping up. Typical signs are payroll that takes days to reconcile, the same data typed into several systems, offboarding that misses an account, and month-end reports that need manual stitching before anyone trusts them.
ERP readiness checklist
- Do you enter the same employee or customer details into more than one system?
- Does payroll need a spreadsheet alongside your payroll tool to reconcile?
- When someone leaves, is there one place that removes all of their access?
- Can you see who has which laptop, and when its warranty ends?
- Do you invoice in more than one currency or tax regime?
- Do managers approve leave, expenses and timesheets in different places?
If you answered yes to three or more, moving to a suite is likely to save more time than it takes to adopt.
What should you look for when choosing ERP software?
Look for shared records across every module, permissions you can narrow to the record, single sign-on with the identity system you already use, support for your countries' tax and invoicing rules, the languages your team works in, and a pricing model that does not charge again for each extra module.
- Shared records: all eight PeopleParity applications use the same people, permissions and data.
- Permissions: five data scopes (everything, team, assigned, own or none), enforced on the server.
- Sign-in: Microsoft Entra ID single sign-on over SAML 2.0.
- Countries: 250 countries selectable, with 27 tax-ID types mapped across 46 countries.
- Languages: English and Arabic, with a genuine right-to-left layout.
- AI access: a Model Context Protocol server, so assistants such as Claude work within each user's permissions.
How much does ERP software cost?
ERP pricing usually follows one of three models: per module, where each application is a separate licence; per user with feature tiers; or per employee across the whole company. Compare the total for your headcount and the applications you need, including implementation, rather than the headline price of a single module.
PeopleParity uses one per-user subscription that includes every application, with no per-module licence fees and no feature tiers. See pricing for details, or browse all eight applications to see what is included.
How do you get started with an ERP suite?
Start with the processes that hurt most, usually payroll and leave or invoicing, and move them first. Import your employee and customer records once, set up roles and permissions, connect single sign-on, then add the other applications team by team. A walkthrough with your own data is the quickest way to judge fit.
