The Ultimate Checklist for Switching Payroll Companies

If you’re thinking about switching providers, you’re in the right place: our ultimate checklist for switching payroll companies. We sat down with Chung Lo, MVF’s payroll expert, to hash out the most important details about switching, and bring you the expert guidance you need to get it right. 

You might want to switch payroll providers for a number of reasons, such as price, problems with your current provider, or changing business needs.

Payroll providers can automatically calculate payroll, calculate, file and pay taxes, and make necessary deductions, such as 401k and insurance. The ever-changing nature of tax regulations means it can be easy to make mistakes or miscalculations – working with the right payroll provider can help prevent this from happening. 


Your checklist for switching payroll companies:

Use this handy-dandy checklist to make the switch to a new provider as painless as possible:

  • Do your research and find a new provider
  • Check your current contract
  • Pick the right time to switch 
  • Notify your current provider
  • Collect all necessary data for the new provider
  • Coordinate tax filings and payments 
  • Carry out parallel runs 
  • Make the switch!

1. Do your research and find a new provider 

Switching payroll providers can be a hassle-free process if you do your due diligence and research, and the benefits of switching should outweigh any difficulties. 

Here are some of the key factors you should look for in a new provider:

    • Costs aligned to your budget – you shouldn’t be paying any hidden costs, or struggling to keep up with your provider's prices. By switching, you can be confident you’re making decisions in alignment with your budget. 
    • More efficient service – this will streamline your business’s operations and make things easier for both you and your employees. You can choose a provider based on your business needs, such as a well-designed portal for employees, automatic payroll, or a full tax service. 
    • Better communication being able to communicate more effectively with your provider should help your business deal with any issues as quickly as possible. Payroll errors can cause huge disturbances, especially when it comes to employee pay or taxes. 

2. Check your current contract 

If you’re tied into a contract, it may be harder to leave when you want – you might have to wait for a specific point in time. However, you can always contact your current provider to see what your options are. 

That said, many payroll providers offer flexible monthly subscriptions, which means you can leave whenever you want.

3. Pick the right time to switch 

Lo told us: “My recommendation would be to initiate the switch effective from April.” This makes it a much smoother process, as year to date (YTD) reporting is cleaner. 

Changing payroll providers mid-year is possible, but it might be a more complicated process, as you’ll need to share your YTD figures with the new provider. There’s also extra paperwork involved and, potentially, greater room for error. 

4. Notify your current provider

You’ll need to let your current provider know that you’re leaving, this is important especially for tax purposes, and to ensure a smooth transition. 

5. Collect all necessary data for the new provider

Lo suggests providing the following data during your switch: 

  • Employee details
  • Salary details
  • Bank account details
  • Company information
  • Relevant tax information

More comprehensive payroll providers may have pre-built integrations with established HR systems – but this is rare, and would still require some data cleansing.

If you’re switching, you’ll probably be moving to a more advanced platform, which means some admin processes may no longer be relevant – great news for increasing your efficiency. 

6. Coordinate tax filings and payments 

When it comes to tax, Lo advises you to “be clear on who will be making the real-time information (RTI) submissions to HMRC and when this crosses over to the new provider” . You’ll also want to get clear on when this process switches to the new provider – knowing this date will help you avoid any duplication. 

If your new provider is full-service, you’ll need to determine the new process for capturing changes from HMRC notifications for tax codes and loan notifications.

7. Carry out parallel runs 

You might be wondering what parallel runs are. We put the question to Lo, who says: “A parallel run is where payroll is run twice, but employees are only paid through one provider, typically the old provider.”

Meanwhile, the new payroll provider processes payroll and generates any agreed reporting, but no payments are made to employees. This allows you to then check that the new payroll has been set up correctly – if it hasn’t, this period can allow for any problems to be solved. Parallel payroll runs are a handy way to ensure a smooth switch. 


Reasons to switch payroll providers 

There are several reasons you might want to switch providers. Here are some of the most popular:

  • Bad communication – miscommunication or simply bad communication can affect the efficiency of your business. If you find it hard to get in touch with your payroll provider or get answers to your questions on time, it might be time to switch. 
  • Unreliability – your current provider might be unreliable, which could have led to severe issues for your business, such as employees not being paid on time or being paid incorrectly. 
  • Size – your business may have downsized or grown, which means you need a provider that more accurately reflects your business size and needs.
  • Price – Your current provider could have become more expensive, especially if hidden costs and charges have padded your invoice, leading you to look for a company that better suits your budget. As Lo told us: ”It can be a pain to reconcile invoices to the expected cost, so it’s important to keep on top of these.”
  • Inflexibility – there are three common pay frequencies: weekly, bi-weekly, and monthly. You may want to pay your employees with multiple frequencies, whereas your provider has limited you to just one or two. 

If you haven’t yet found a new payroll provider to switch to, use the reasons you’re switching to help inform you on your search. Identify what’s most important to you, or the problems you currently have, so you can find a provider that’s right for your business.

Common mistakes to avoid when switching payroll providers 

There are lots of pitfalls involved in switching payroll providers, but following this guide should help you to dodge them. Here are the most common mistakes you want to avoid to ensure a smooth transition to your new payroll provider:

  • Misunderstanding pricing – Payroll pricing is not always straightforward. For example, there may be discounts for businesses of a certain size, or one-off charges for implementation. Make sure you know what the costs will be upfront so you aren’t hit by any unexpected charges. 
  • Not informing stakeholders – Payroll affects several stakeholders and it’s important that any links to your payroll are involved in the switch. Inform all the relevant stakeholders in order to prevent any errors. 
  • Lack of integrations – If your new payroll software is being integrated with a HR system, the new provider will need to rebuild these integrations. Failing to be aware of these impacts can lead to broken reporting and data errors. 
  • Not staying on top of any unique policies – Your company may have a unique company scheme that your new payroll provider will need to be able to accommodate. Before switching, ensure the new provider can meet your business needs and, during the switch, keep an eye on the new provider to prevent any issues with pay.
  • Running out of time – You want to make sure there’s enough time to run parallel runs between the previous payroll provider and your new provider to work through any teething issues – this eliminates the risk of employees not getting paid on time.
