Call for Evidence: Business Systems Integration
Published 12 March 2026
Summary
Aims and objectives of this call for evidence
The purpose of this call for evidence is to gather views on the role business systems integration could play in making it easier for businesses to keep records.
Scope of this call for evidence
The call for evidence will explore how businesses keep records, the integration of digital systems used by businesses to make sales and their accounting software or business bank account, and any challenges or difficulties relating to the set up and use of integrations.
The integrations in the scope of this call for evidence operate within a business’ own systems and do not involve data being shared with HMRC. The information you provide will help identify practical steps for government and industry to make integrations more useful for businesses, and to understand what software providers need to make better-connected products.
We do not anticipate introducing requirements for businesses to integrate their systems as a result of this call for evidence.
Who should read this
The government is interested in responses from small and medium sized businesses, sole traders, tax advisers and accountants, software providers and business systems providers, financial technology companies, industry bodies and trade associations, and researchers or academics with expertise in digitalisation or business systems.
Duration
The call for evidence will run for 12 weeks from 12 March 2026 to 4 June 2026.
Lead official
The lead officials are Kylah Jacobs of HM Revenue and Customs (HMRC) and Paramdeep Khera of Department for Business and Trade (DBT).

1. Foreword
Digitalisation is reshaping how small businesses operate, creating opportunities to reduce time spent on administration and remove potential for mistakes. Integrating the systems that businesses already use could free up time spent manually recording transactions, giving businesses an accurate, up to date view of their finances, and simplifying their fulfilment of tax reporting obligations.
This call for evidence seeks insights to help government understand how businesses use digital systems for record keeping, and in particular the uptake and availability of integrations that enable the automatic transfer of sales and purchase data into businesses’ accounting software. Our goal is to find ways to support businesses, not introduce requirements. This will help them to focus on growth, rather than administration.
We are pleased that our departments — DBT and HMRC — are working together to support business growth and streamline tax administration for businesses. We look forward to hearing from businesses, civil society, software and business systems providers, and the wider accountancy profession.
Dan Tomlinson MP
Exchequer Secretary
Blair McDougall MP
Minister for Small Business and Economic Transformation
2. Introduction
Growth is this government’s number one mission, and small and medium sized businesses are critical to this, making up 99.8% of the UK business population. The government’s plan for small and medium sized businesses focuses on five key actions to enable them to thrive. One of these actions is future-proofing business skills by increasing adoption of technology, to boost productivity and reduce the time spent on administration. Enterprise Nation’s research suggests that small business owners who embrace technology could unlock three and a half weeks of time each year. This aligns with HMRC’s vision for tax administration, as a simpler, easier process that works effectively alongside the systems businesses already use.
Running a business involves managing a wide range of responsibilities. Accurate record keeping is essential for businesses to understand their financial position, manage cashflow effectively, track performance, and get their taxes right.
New technology is enabling businesses to move towards digital and real-time record keeping. Digital, integrated systems can provide real-time visibility of a business’ income and expenses. As these capabilities evolve, we want to ensure that they work effectively and accurately, and provide businesses with the support they need as they adopt them.
However, we know that navigating this landscape can be challenging. Small businesses are often time-constrained and therefore may have limited time and resource for the adoption of digital tools.
This call for evidence aims to identify how government can support better digital systems for businesses, and in particular the uptake and availability of integrations between the systems businesses already use.
3. What is business systems integration?
Most small businesses use software or business bank accounts to manage their finances and taxes [footnote 1], alongside other digital systems that facilitate sales and purchases.
Examples of those other systems include:
- electronic point of sale (EPOS) machines
- card machines
- e-commerce and booking platforms
- bank feeds
- payment services providers
- customer relationship management (CRM) systems
There are also other, industry-specific products.
Integration can connect these systems with accounting software (or a business bank account with equivalent functionality), enabling data to flow automatically between them and removing the need for manual entry. For example, linking an e-commerce platform to accounting software can ensure that sales data is recorded automatically and accurately. This would mean accurate data on sales, refunds, and platform fees would flow straight into the customer’s accounting software, typically on a daily basis, posted to the right place on the customer’s ledger.
Most integrations between accounting software and other business systems use Application Programming Interfaces (APIs) to enable secure data exchange. Integrations are typically delivered through an app-store model, hosted by the accounting software provider or through third-party integrators. This enables businesses to connect systems without needing to build custom integrations.
What are the benefits of business systems integration?
Integration could reduce administrative burdens and provide businesses with more real-time, accurate financial information.
Connecting the digital systems that businesses already use could:
- save businesses time by reducing manual data transfer
- help businesses see real-time financial information to manage cashflow and support timely payments
- make it easier for businesses to do their taxes, and reduce errors in tax returns
- make it easier for tax advisers to support their clients and focus on real-time insights and advice
4. About this call for evidence
We want to understand how businesses use digital record keeping, and the role integration could play in improving this process.
We want to explore:
- whether businesses have integrated any of their digital systems
- how much time businesses spend on record keeping, and whether integration reduces it
- whether integration works differently for different sectors
- any challenges businesses face when setting up or using integrated systems
- when tax advisers recommend integrated systems and what barriers they observe
This information will help identify practical steps for government and industry to make integrations more useful for businesses, and to understand what software providers need to make better-connected products.
The government does not anticipate implementing regulation or requiring businesses to integrate their systems as a result of this call for evidence. Your insights will help shape future policy and support efforts to make digital tools work better for small businesses.
Wider objectives
This call for evidence forms part of the broader government effort to boost economic growth and productivity, help businesses manage cashflow and reduce errors in tax returns.
It is informed by other initiatives such as:
- the plan for small and medium sized businesses, which aims to accelerate small business growth, including by driving digital adoption, improving access to finance, and reducing administrative burdens. Integrated business systems could facilitate this by giving businesses an accurate view of their finances and making it easier to do tax
- e-invoicing, which is the external data exchange of invoice information directly between buyers’ and suppliers’ financial systems. The government has announced that e-invoicing will be mandatory for all VAT invoices from 2029 and the design of the approach is being developed jointly with industry. Business systems integration is different in scope - it is about linking a business’ internal systems. This could complement the benefits of e-invoicing by helping businesses automate record keeping for sales and purchases that do not generate an invoice. It is, however, a separate area of activity with different drivers and use-cases
- Making Tax Digital, which will start being rolled out to self-employed individuals and landlords with income over £50k in April 2026. Those with an income of more than £30k will come on board from April 2027, and those with income of more than £20k from April 2028. This will increase small business digitisation and expand the number of businesses with access to digital integration options
