Who Should Handle Your Accounting Software Setup: Owner, Accountant or IT Team?

Choosing accounting software is only the first step. Once you have selected a solution, someone needs to prepare the business data, configure the accounts, set up users and make sure the software works with your existing processes. Without clear responsibilities, these tasks can overlap or get missed.

This is where businesses often face a practical question: who should implement accounting software? Should the owner take charge, should the accountant handle everything, or does the IT team need to lead the process?

There is no single answer for every business. The right approach depends on the size of your team, the complexity of your accounts and the technology you use. However, one principle remains the same: implementation works best when one person owns the overall process, and each team knows what it needs to deliver.

Role of the business owner in accounting software setup

The business owner should take responsibility for the overall implementation. This does not mean handling every technical or accounting task personally. Instead, the owner sets priorities, approves important decisions and ensures the software meets the business's actual needs.

For example, a retailer may need billing, inventory tracking and customer payment records, while a service business may focus on invoicing, expenses and project-related income. The owner understands these day-to-day requirements and can help the team decide which features matter most.

The owner's responsibilities typically include:

• Defining what the business expects from the software.
• Approving the budget, implementation timeline and major decisions.
• Assigning responsibilities to the finance and IT teams.
• Reviewing progress and resolving delays or disagreements.
• Approving the system before it is used for regular business operations.

The owner should also decide who will be accountable for the project. Even when an accountant or software provider handles most of the setup, someone within the business needs to track progress and make sure the agreed-upon tasks are completed.

The owner should also make sure implementation does not happen in isolation from the rest of the business. Changes to billing, purchasing, inventory or reporting can affect employees outside the finance team. Discussing these changes early gives employees time to raise concerns and helps the business avoid surprises after the system goes live. 

Role of the accountant or finance team

The accountant or finance team should manage the financial side of the accounting software implementation roles. They understand how transactions are recorded, which reports the business needs and what is required for accounting and compliance.

Their responsibilities include setting up accounts, opening balances, tax details and reports. During accounting software implementation, they should also check that sales, purchases, expenses and payments follow the right workflows.

The finance team should verify opening balances and review key reports before go-live. Businesses using TallyPrime should also check that the chosen configuration supports their accounting and reporting needs.

Finance should also document the accounting practices that need to remain consistent after the switch. This can include how customer payments are recorded, how expenses are categorised, how credit transactions are handled and which reports are reviewed regularly. Writing these processes down makes training easier and gives employees something to refer to when questions arise. 

Role of the IT team

Not every small business needs a dedicated IT team for its software setup. However, technical support becomes important when the system involves multiple users, existing business applications, data migration or specific security requirements.

The IT team can assess whether the software will work with the business's current devices, network and other systems. It may also handle technical integrations, data access, backups and security settings, depending on the software and deployment method.

IT should not make accounting decisions without input from the finance team. Its role is to make sure the system works securely and reliably, while the accountant determines how financial transactions and records should be handled.

For smaller businesses without dedicated IT staff, these technical responsibilities may be shared between the owner, software provider and an external technology professional. What matters is that someone is clearly responsible for each task rather than assuming that another person will take care of it. 

Who should prepare and check the business data?

Before setting up new accounting software, make sure your business records are complete and accurate. You may need to organise customer and supplier details, product lists, outstanding invoices, stock records and opening balances.

The finance team should check account balances and financial information, while sales, purchasing and inventory staff can verify their respective records. The owner should ensure everyone completes their part on time.

Remove duplicates, correct known errors and back up the original records before migration. Test a small batch first. After the import, ask the relevant teams to check their records and reconcile key totals, including opening balances and outstanding amounts, against the original records. Resolve any differences before regular use.

A useful way to organise this stage is to divide the data into categories and assign an owner to each one. For example:

• Customer and supplier records: sales or finance team.
• Product and stock information: inventory or purchasing team.
• Opening balances: accountant or finance lead.
• Employee and user information: owner, HR or authorised administrator.
• Historical accounting records: finance team, with support from the software provider where required.

This approach makes it easier to identify missing information before migration rather than discovering gaps after the new system is already being used.

Who should configure the accounting software?

Configuration means setting up the software to suit your business. This may include account groups, invoice formats, tax details, inventory options and reporting preferences.

The finance team should handle accounting settings, while the owner approves decisions that affect business operations. IT can manage technical settings and integrations, and the software provider can guide the team through available features.

Give each person a well-defined role. The accountant should decide how transactions are entered, and the owner should sign off on workflows when necessary. IT can manage the technical setup, but should not make accounting decisions.

Before using the software for regular business activity, enter sample transactions and check the resulting reports. Resolve any configuration problems, obtain go-live approval and then begin regular use.

Do not limit testing to one successful transaction. Try scenarios that employees are likely to encounter during normal work, including corrections, cancelled transactions, customer payments, supplier payments and returns. This gives the team a better idea of how the system behaves when the process is not completely straightforward. 

Who should set up user access and controls?

Not everyone needs access to every part of the digital accounting system. A salesperson may need to create invoices, while an accountant may require access to financial reports, reconciliation and account settings. The owner may need an overall view of business performance.

Assign user roles based on each individual's responsibilities. Don’t give everyone one login to share; instead, restrict access to potentially sensitive information or critical configurations. With individual accounts, it’s easier to control permissions and know who did what.

The owner should sign off on the overarching access policy, and finance/IT can help translate it into specific permissions. The precise split will depend on the application and the company’s internal controls.

Access should also be audited for employees who change roles or leave the company. Such audits are essential to protect financial data and ensure the records have not been tampered with.

Who should train employees?

Even a well-configured system can create problems if employees do not know how to use it. Training should therefore be part of the implementation plan, rather than something arranged after the software goes live.

Each person should learn the tasks they will perform. Sales staff may need help with billing, while finance employees may require training in reconciliation, reporting and account management. Owners should understand how to access important reports and review business performance.

The software provider may offer demonstrations, guides or structured accounting software onboarding. Internal team members can then explain how those features fit into the business's daily processes.

Allow employees to practise common tasks before switching completely to the new system. A short reference guide for routine activities can also help reduce repeated questions and make the transition easier.

What support can the accounting software provider offer during setup?

The accounting software provider can help the business understand the product, configure supported features and resolve setup issues. Depending on the service offered, support may include data migration guidance, training, technical assistance or help with integrations.

However, vendor support should complement internal ownership rather than replace it. A provider can explain how a feature works, but the business must decide how it should be used and who is responsible for maintaining the information.

Before implementation begins, clarify what the provider will handle, what the business must complete and whether additional support comes at an extra cost. This helps prevent delays caused by assumptions about who is doing the work.

For a solution such as TallyPrime, businesses should confirm which implementation, training and support services are available for their chosen setup.

Creating an accounting software responsibility matrix

A responsibility matrix makes it easier to see who owns each task when it comes to handling new accounting software. The following example can be adapted to suit your team and the complexity of your implementation.

The business owner should remain accountable for the overall timeline, even when individual tasks are assigned to other people. Regular check-ins can help identify unfinished work, resolve questions and confirm that the system is ready for use.

Before the final go-live approval, bring different teams together for one last review. Each person should confirm that their assigned responsibilities are complete and that any unresolved issues have an owner and a clear next step. This final check is particularly useful when several teams or an external software provider are involved.

A practical go-live checklist can include:

• Financial data has been reviewed, and opening balances have been verified.
• Users have the correct permissions for their roles.
• Important workflows have been tested with sample transactions.
• Required reports have been checked by the finance team.
• Employees have received training for their regular tasks.
• Data backups or recovery arrangements have been confirmed where applicable.
• The team knows where to go for technical or product-related support.
• The owner or designated project lead has approved the switch to regular use.

This checklist doesn't mean every implementation needs to be complicated. For a small business with a few users, the owner and accountant may handle most responsibilities themselves, with occasional support from the accounting software provider. The key is to match the implementation process to the business's size and needs.

Wrapping up

Setting up accounting software for a small business is a shared effort. The owner should lead the project, the accountant should manage financial records, and IT should handle technical needs. Software providers can offer guidance and support. Clear responsibilities help prevent errors and delays. Agree on who will prepare data, configure the system, test its features and train employees before going live.

Before you go live, take a step back and look at the complete process from the user's perspective. Check whether employees can complete their routine work, whether the finance team can generate the required reports and whether the owner can access the information needed to make business decisions. If something feels unclear during testing, address it before the system becomes part of everyday operations.
