• Implement a cloud-based ERP system to connect your finance, inventory, and reporting systems into one unified platform that automatically syncs data across all business applications in real-time.
• Prioritize the four core ERP components for small businesses: accounting and financials, customer relationship management (CRM), inventory management, and human resources to streamline operations effectively.
• Utilize ERP automation to eliminate manual data entry between systems, reduce errors from data inconsistencies, and free up time to focus on strategy and customer relationships rather than administrative tasks.
• Start with your existing accounting software as the financial hub and connect it to specialized apps to create a flexible, ERP-like system without the complexity and cost of traditional enterprise solutions.

What is an ERP system?

Enterprise resource planning (ERP) systems are centralized platforms that connect all your business software and share data automatically. Instead of managing separate systems for accounting, inventory, sales, and HR, ERP creates one unified database.

This integration removes barriers between your systems and gives you one place for all your business information. When your sales team closes a deal, your inventory, accounting, and fulfilment systems update instantly.

How ERP solutions work

Modern ERP systems automatically sync data across all your business applications using cloud-based technology. Analysts expect the global cloud ERP market to reach over $181 billion by 2032.

Here's how the process works:

• Data collection: ERP pulls information from all connected systems in real-time
• Two-way sync: Changes in one system automatically update everywhere else
• Data reconciliation: ERP eliminates conflicts and ensures everyone works with the same numbers
• Cloud access: Access your unified data from anywhere, on any device

Types of ERP systems

ERP systems come in different types, but for a small business, the choice usually comes down to how the software is hosted. Understanding the options helps you pick the right fit for your needs and budget.

• Cloud ERP: This is the most popular choice for small businesses, with recent data showing that 64.5% of organisations selected cloud-based ERP software over on-premise solutions.
• On-premise ERP: With this option, you buy the software license and install it on your own servers. It offers more customisation but requires a large upfront investment and an IT team to manage it.
• Hybrid ERP: This approach mixes cloud and on-premise solutions. For example, you might keep your core financials on-premise but use a cloud app for customer management.

Most small businesses find that a flexible, cloud-based approach gives them ERP-style visibility and automation without the complexity or cost of traditional systems.

Core ERP components for small businesses

Core ERP components for small businesses include four essential tools that work together to streamline operations. A simple, focused system is enough for you to benefit from ERP.

The essential components are:

• Accounting and financials: Track money in and out, manage your general ledger, and handle financial reporting
• Customer relationship management (CRM): Manages all your customer interactions, from initial contact to sales and support
• Inventory management: Tracks stock levels, manages orders, and helps you avoid running out of your best-selling products
• Human resources (HR): Handles payroll, employee records, and time tracking to keep your team running smoothly

Benefits of ERP systems

ERP systems deliver four measurable benefits that directly improve your profits and business efficiency:

Centralized data

Centralized data: Eliminates the chaos of managing multiple spreadsheets and disconnected systems by consolidating information from every department into one real-time database.

Benefits include:

• No more manual data entry between systems
• Fewer errors from data inconsistencies
• Everyone working with the same accurate numbers

Improved decision making

Improved decision making: Get real-time dashboards showing sales, inventory, cash flow, and performance metrics in one place instead of hunting through multiple systems.

This allows you to:

• spot trends quickly
• solve problems early
• make decisions based on up-to-date information, as ERP systems can reduce business decision time by 36%

Automation

Automation: ERP software automates repetitive tasks and makes your processes faster.

Common automation examples include:

• Financial reporting and reconciliation
• Customer outreach and follow-ups
• Stock management and reordering
• Marketing campaign triggers

Increased productivity

Increased productivity: Better analytics, informed decisions, and automated tasks reduce waste and increase overall business efficiency by eliminating time spent on manual processes.

Why is ERP important for small businesses?

ERP is important for small businesses because it eliminates time-consuming admin work and connects different parts of your business automatically. You started your business for more flexibility and control, not to get stuck in spreadsheets.

As you grow, managing separate systems takes up more time. ERP solves this by linking sales and inventory, or projects and payroll, giving you a clear, real-time picture of your business's health.

This automation frees you to focus on strategy, customer relationships, and the passion that got you started.

ERP vs other business systems

ERP differs from other business systems in scope and functionality. Here's how ERP compares to common alternatives:

ERP vs CRM

A customer relationship management (CRM) system focuses on managing your interactions with customers, like sales and support.

An enterprise resource planning (ERP) system is broader and brings together data from across your business, including finance, human resources, and supply chain, often including a CRM as one of its components.

ERP vs accounting software

Your accounting software (like Xero) is the financial engine of your business. An ERP system integrates that financial data with information from all other departments.

For many small businesses, using a powerful accounting platform that connects with other specialised apps creates a flexible, ERP-like system without the cost and complexity of a traditional, monolithic ERP.

ERP examples and use cases

ERP examples show how businesses use integrated systems to automate workflows and improve efficiency across different industries:

• A retail shop can connect its point-of-sale (POS) system to its inventory and accounting software. When a sale is made, inventory levels update automatically, and the revenue is recorded in the books, giving the owner a real-time view of sales and stock.
• A construction company can use an ERP approach to link project management tools with payroll and invoicing. This ensures that project costs are tracked accurately, staff are paid for the correct hours, and clients are billed on time.
• An ecommerce business can integrate its online store with its shipping and accounting platforms. This automates the entire order-to-cash process, from the moment a customer clicks 'buy' to when the payment is reconciled in the bank.

Getting started with ERP

Getting started with ERP involves four straightforward steps that most small businesses complete within their first month. Modern cloud-based solutions require no IT expertise or expensive hardware.

Here's how to implement ERP:

1. Choose a cloud ERP solution that fits your industry and budget
2. Connect your existing software through built-in integrations
3. Import your current data with guided migration tools
4. Train your team using the provider's onboarding resources and validate your system setup

Your ERP provider handles security, updates, and maintenance automatically. Most small businesses see results within the first month of implementation.

With Xero as the financial hub, you can connect to over 1,000 third party apps to build a system that's right for your business. See how you can run your business, not just your books, andtry Xero for free.

FAQs on enterprise resource planning

Here are answers to common questions small businesses have about implementing and using enterprise resource planning systems.

What is an ERP example?

If you run a retail business, you can connect your sales, inventory, and accounting software. When you sell an item, your system updates stock levels and financial records automatically, giving you a complete, real-time view of your business.

What is ERP vs CRM?

A customer relationship management (CRM) system focuses on managing your interactions with customers, like sales and support.

An enterprise resource planning (ERP) system is broader and brings together data from across your business, including finance, human resources, and supply chain, often including a CRM as one of its components.

Is ERP only for large companies?

Modern cloud-based ERP systems are now affordable and scalable for small and medium-sized businesses. While traditional ERP systems were built for large corporations, you can now use similar tools at a size and price that suit you.

Many small businesses create an ERP-like system by integrating specialised apps with their core accounting software.

How much does ERP cost for small businesses?

Costs vary widely, though one study found the average budget per user to implement ERP is about $9,000. Instead of a single large investment, many small businesses build their system using affordable, subscription-based apps.

How long does ERP implementation take?

If you build a system with integrated cloud apps, you can get set up quickly. It still pays to plan carefully. Research shows companies spend 17 weeks on average selecting ERP systems.

This is much faster than setting up a traditional ERP system, which could take months or even years.
