ERP Implementation Checklist: 20 Things Businesses Should Prepare

In terms of the software, an ERP project may appear straightforward: Just purchase a vendor, install modules, import data, train users, and launch the software.

In practice, the difficult part usually happens before the software is switched on.

There are processes to agree on, existing data to clean, responsibilities to assign, user preparation, integrations to review, and what success looks like to be determined. This ERP Implementation checklist includes 20 points that businesses need to do before and during ERP System implementation and some real-life considerations for Indian businesses.

Why an ERP Implementation Checklist Matters

ERP software integrates various business functions like finance, procurement, inventory, sales, HR, manufacturing, and supply chain. This can have a knock-on effect on other issues.

An example of this might be, that when an item is purchased or produced with an incorrect item code, it could impact purchasing, inventory, production, sales orders, and financial reporting. Not knowing who authorized your work can also cause delays from one department to another.

A solid ERP implementation checklist assists the business with recognizing these dependencies before they turn out to be costly issues.

ERP Implementation Checklist: 20 Things to Prepare

1. Define the Business Goals

Start with the business problem, not the software.

Determine the changes that the ERP system will help to make. Your objectives could be to decrease manual data entry or increase the visibility of inventory or shorten the financial closing cycle or increase production planning or connect multiple locations.

Keep the goals measurable where possible.

2. Define the Project Scope

Clearly decide which departments, locations, processes, and ERP modules are included in the first phase.

For instance, a manufacturing firm might begin by using finance, purchasing, inventory, production and sales instead of using all of the optional modules.

A clearly defined scope helps control the ERP implementation process and reduces scope creep.

3. Get Executive Sponsorship

Multiple departments will be impacted by ERP implementation, and senior leadership must be actively involved in the project. 

Have an executive sponsor who can represent on big issues, can approve major decisions, and keep the project on track to meet the business goals. 

Without clear leadership, implementation decisions can become slow and fragmented.

4. Build a Cross-Functional Project Team

Do not leave the project entirely to the IT department.

Have members from finance, operations, sales, HR, procurement, inventory and other involved teams. Assign clearly defined roles to individuals.

A practical ERP implementation team may include:

• Executive sponsor
• Project manager
• IT lead
• Finance representative
• Operations representative
• Department-level key users
• ERP implementation partner

This gives the project both technical and business ownership.

5. Map Current Business Processes

Before changing a process, document how it currently works.

Map important workflows such as:

Purchase request → approval → purchase order → goods receipt → invoice → payment

Do the same for sales, inventory, production, payroll, and financial reporting.

This will ensure unnecessary manual tasks are uncovered, and the ERP implementation approach is more realistic.

6. Identify What Should Be Standardized

ERP software may come with pre-built workflows. Companies need to identify the processes that should be customized and those that can work with the ERP's default functions. 

Customizing too much can make it more complex to implement, maintain, and upgrade the system in the future.

A good question to ask is: is this process adding value to the business or is it a habit that's being retained?

7. Prepare the Master Data

Data preparation is one of the most important parts of an ERP data migration project.

Review and clean:

• Customer records
• Supplier records
• Product and item masters
• Employee records
• Chart of accounts
• Warehouses and locations
• Units of measurement
• Tax information

Remove duplicates and standardize naming and codes before importing anything.

ERP software will not automatically fix poor-quality source data.

8. Decide What Historical Data to Migrate

You do not necessarily need to move every record from your old systems.

Decide what information the business needs in the new ERP and what can remain archived.

You can move over existing customer balances, open purchase orders, inventory balances, and selected transaction history, while retaining older transactions in an easily accessible archive.

This can make ERP data migration easier to validate.

9. Confirm Indian Tax and Compliance Requirements

For Indian businesses, ERP preparation should account for applicable GST and invoicing requirements.

Look at GSTIN information, HSN/SAC details, tax settings, invoice formats, and e-invoicing workflows applicable. The GST e-invoice system has the e-invoice APIs and other integration options for ERP and billing systems.

Your requirements may vary depending on your business, transaction type and regulations and should be checked with the relevant tax or finance expert.

10. List Every Required Integration

Create an integration inventory before implementation begins.

Consider systems such as:

• Banking and payment platforms
• E-commerce platforms
• CRM software
• Payroll systems
• POS systems
• E-invoicing services
• Business intelligence tools
• Existing accounting applications

Document what data needs to move between each system and how frequently it should synchronize.

11. Define User Roles and Permissions

Decide who can view, create, approve, edit, and delete information.

For example, a purchase executive may create purchase orders, while a manager approves them. Finance may access invoices and payments without having permission to modify inventory records.

Role-based access should be designed before users are onboarded.

12. Set Approval Workflows

ERP implementation is a good opportunity to formalize approvals.

Define approval thresholds for areas such as:

• Purchases
• Discounts
• Expenses
• Vendor creation
• Credit limits
• Payments
• Sales orders

Write these rules down rather than leaving them as informal departmental practices.

13. Prepare Reports and KPIs

List the reports management actually uses before configuring the ERP.

These might include:

• Profit and loss
• Cash flow
• Inventory ageing
• Sales performance
• Outstanding receivables
• Payables
• Production efficiency
• Purchase performance

This ensures the ERP implementation plan is connected to business decisions rather than simply system features.

14. Set the Budget and ERP Implementation Timeline

Your budget should cover more than the software subscription or licence.

Consider:

• Implementation services
• Data migration
• Integrations
• Customization
• Training
• Additional users
• Hardware, if applicable
• Support
• Internal employee time

It doesn't just stop on the go-live date—testing, training, data validation, and post-go-live support are also part of the ERP implementation timeline.

15. Plan Change Management

Employees who lack awareness of the reasons behind changes to processes may exhibit resistance to the ERP system.

Discuss what has changed, why it has changed, and what the impact of the new workflow will be on each team.

Examine the organisation and identify others who will be capable of being internal ERP champions and mentor others to support the change.

Change management is not a final-stage activity. It should be part of the ERP implementation strategy from the beginning.

16. Create a Role-Based Training Plan

Do not give every employee the same training.

An accountant needs different training from a warehouse executive or sales manager.

Create training around actual responsibilities and workflows. Use realistic transactions instead of only demonstrating menus and features.

This makes ERP user training much more useful and improves confidence before go-live.

17. Test Real Business Scenarios

Testing should go beyond checking whether individual features work.

Run complete business scenarios, such as:

Purchase order → goods receipt → supplier invoice → payment

or:

Sales order → inventory allocation → dispatch → invoice → payment

This is one of the most important ERP implementation best practices because problems often appear when multiple modules interact.

18. Reconcile Migrated Data

After data migration, compare the new ERP against the old system or approved source records.

Check important figures such as:

• Opening balances
• Inventory quantities
• Customer balances
• Supplier balances
• Outstanding invoices
• Product counts

Do not assume that a successful import means the data is correct.

19. Prepare the Go-Live and Backup Plan

The right ERP go-live checklist will ensure that users, workflows, reporting capabilities, and critical data are ready, as well as training.

Also decide what happens if a serious problem appears after launch.

Define:

• Who handles urgent issues
• How users report problems
• What systems remain available temporarily
• Who can make go/no-go decisions
• How critical transactions will be handled during an outage

A fallback plan is particularly important for businesses that cannot afford operational downtime.

20. Plan Post-Go-Live Support

ERP implementation does not end when employees receive their login credentials.

The first few weeks can expose workflow problems, training gaps, incorrect configurations, and unexpected reporting requirements.

Plan a structured support period, often called hypercare, with clear issue ownership and response priorities.

Once the process has been stabilized, look at what is successful, what should be changed, and what changes can be implemented at a later time. 

Pro-tip

Prior to go live, have 5 employees from varying departments at your company perform some of the most frequent tasks they do every day in the new ERP without support. Document any difficulties, errors, or workarounds. Those observations can in turn provide insights that formal testing cannot into usability and training needs.

Common ERP Implementation Challenges to Watch For

Even with a detailed ERP implementation checklist, some risks can still affect a project:

• Poor data quality: Incorrect or duplicate data can cause problems after migration.
• Unclear ownership: Delayed decisions can slow implementation.
• Scope creep: New requirements can increase the ERP implementation timeline and budget.
• Too much customization: Excessive changes can make the system harder to maintain.
• Low user adoption: If the training and/or processes are not reliable, employees will revert to spreadsheets and old systems.

The challenges illustrate the need to pay attention to people, processes, data, and technology – not just configuration – to ensure a successful ERP implementation.

What Should Indian Businesses Look for in an ERP?

Indian businesses should evaluate ERP software against their actual operating environment.

Depending on the business, this can include GST workflows, e-invoicing, multi-location inventory, Indian accounting requirements, payroll, manufacturing, procurement, and integrations with existing business applications.

For SMEs, the right system does not necessarily mean the largest system. A smaller implementation with clearly defined modules may be more practical than deploying a highly complex ERP before the business is ready.

ERP Implementation Checklist: A Simple Readiness Test

Before moving toward go-live, ask:

If several answers are still "no", the business may not be ready for implementation yet.

Conclusion

It is not a question of selecting the best software for ERP implementation. It's about getting your people, processes, data and systems ready for go-live.

Check your readiness, overcome common ERP implementation problems, and create a feasible ERP implementation strategy in this ERP implementation checklist. If you are an Indian business, ensure that your plan includes GST, e-invoicing, accounting and multi-location considerations.

The best way is to avoid rushing to go live by selecting an ERP that meets your company's requirements and getting ready for the implementation.
