What’s the difference between small business accounting and bookkeeping?Small business accounting and bookkeeping are closely related but distinct financial processes that both play vital roles in managing a company’s finances.Bookkeeping involves recording your daily financial transactions, maintaining accurate records, categorising the transactions, and ensuring that all financial data is organised.Accounting encompasses the full interpretation and analysis of financial data to provide insights into a company’s financial health.Accountants use the information prepared by bookkeepers to generate statements, such as profit and loss statements and balance sheets. They also offer strategic financial advice, help with tax planning, and can provide a deeper understanding of a company’s overall financial performance.In summary:Bookkeeping: primarily concerned with recording financial data accuratelyAccounting: using that data to make informed financial decisions and meet regulatory requirements What is a small business according to HMRC? According to the official government guidance on small and dormant companies, to be considered a small company, a company has to tick two of the following three boxes:Have an annual turnover of £10.2m or lessHave 50 employees or fewerHave £5.1m or less on its balance sheetWhereas micro-entities, or very small companies, are defined by having any of the two following criteria:10 employees or fewer£316,000 or less on its balance sheeta turnover of £632,000 or less The best small business accounting softwareQuality accounting software can digitally create and store purchase orders, invoices, quotes, and anything else produced by the business. Some of the top-end plans have even added extra features like cash flow forecasts and tax bill estimates.If you’re concerned you might not be able to budget for the cost of accounting software, it’s worth knowing that there is a range of free accounting software available to use. Just note that these options can be very limited and won’t be as sophisticated as their paid counterparts. 0 out of 0 backward forward Rating Price From BEST FOR Free Trial FEATURED PROVIDER BEST OVERALL Xero Zoho Books QuickBooks FreeAgent Sage FreshBooks Clear Books 4.3 4.8 4.5 4.5 4.2 4.1 4.0 £16 per month (excl.

From a legal perspective, you’ll need to make sure that the accounting software you’re using is Making Tax Digital (MTD) compliant.Making Tax Digital for value-added tax (VAT), which was introduced back in April 2019, requires all VAT-registered businesses, including those that are voluntarily registered, to store their VAT accounting records digitally, using HMRC-recognised accounting software. QuickBooks and FreshBooks, for example, are both MTD-compliant.MTD if you’re self-employedIf you’re self-employed, you need to be aware of the MTD for Income Tax scheme instead, which is set to be introduced in phases from April 2026.It requires self-employed people with a gross income of more than £30,000 per year to use compatible accounting software that can submit quarterly income and expense reports to HMRC, and also submit ‘end of period statements’ at the end of the financial year to replace Self Assessment tax returns. How do I plan my annual accounts?To effectively plan your annual accounts, follow these best practices (remember, fail to plan, and you plan to fail. It’s a cliché, but it’s definitely how you should approach accounts season!):1. Keep track of your recordsIt’s critical to keep proper records during the year to avoid tearing your hair out at crunch time. You’ll need to be able to easily get hold of your sales receipts, payment invoices, and tax returns.This doesn’t just make a big difference when you’re putting together your end-of-year accounts, either — keeping on top of your records while you run your business will mean having a much better grasp on what money is coming in and going out.2. Utilise accounting softwareUsing accounting software means you’ll be able to create invoices, quotes, estimates, and almost all the other business documents that you might need on the go. Everything is stored in the cloud, meaning that you can access this important data from whichever device you’re working on. Some of the more comprehensive plans will even estimate your tax bill as you progress through the year.3. Decide on a plan of actionWhen it comes to actually putting together your end-of-year accounts, you first need to decide just how much work you’re willing to do yourself. You will almost certainly have to use an accountant at some point, but keeping accurate records (as discussed above) will reduce their workload (and billable hours).4. Get expert insightOnce you’ve hired an accountant, you should see them as a useful resource. Make sure to ask how you could reduce your tax bill before the end of your financial year.For example, you can sometimes make significant tax savings by bringing forward certain expenditures to reduce your company’s profit in that financial year.5. Prepare for the next yearJust as importantly, once the end-of-year accounts have been submitted, it’s a great idea to book a closing meeting with your accountant to identify areas for improvement over the coming year.You could ask their opinion on whether you should upgrade your accounting software (or how it could help your business if you’re not using it), or how you can manage your creditors more effectively. You can also get expert insight into controlling costs, making tax savings, and managing your business’s cash flow more effectively. Is it mandatory to hire an accountant? No, it’s not mandatory to hire an accountant if you’re using accounting software, but their expertise can be incredibly beneficial.Barry Cumberlidge, Client Director at small business accounting specialists Moose, strongly backs up this view:“You can prepare and submit your own company accounts, but a tiny minority choose this option as the software available to do this is limited. It would only be advisable if you’re a qualified accountant, but even in these circumstances, they tend to employ Moose to file on their behalf.”Cumberlidge also identifies three areas in which accountants can really help small businesses:Incorporation – If you are starting a business with a colleague, an accountant can help ensure the right structure and that associated agreements are in place. They can also, as Cumberlidge puts it, “assist in asking the founders the tough governance questions”.Investment – For any company seeking investment, having neat books to show prospective investors is incredibly important. Additionally, an accountant can help you apply for funding through the Seed Enterprise Investment Scheme (SEIS) and/or the Enterprise Investment Scheme (EIS), which offer tax relief to individuals who invest in your company.Tax savings – This is the crucial benefit for most companies. Using an accountant will ensure that you are claiming all of the costs you can and utilising all capital allowances, meaning you pay less tax. They can also help you with applying for R&D tax credits, which can provide a handy cash injection for eligible businesses. What accounting records do I need to keep (and for how long)?It’s important to keep a record of almost everything that happens in your small business. But the key accounting records you are legally required to keep include:Income and expenditure records – These record when and how your business spends and makes money. Keep records of all sales and purchase receipts, cheque books, and up-to-date bank statements.Unsold stock and uncompleted work at year-end – These are known as ‘floating assets’ and are really important for service businesses that often have work in progress that cannot be counted as fixed assets (see below).A register of fixed assets – A list of the equipment and property your company owns, including the value of each piece and other important information. It does not include stock, which would come under ‘floating assets’.A record of company liabilities – Things your company owes. In other words, this should be an accurate and complete record of any debt or investment your company has taken on.Staff payroll information – HMRC keeps a particularly close eye on payroll and expenses matters, so make sure you keep accurate records of who’s been paid what and who’s claimed expenses for what.If you don’t keep accurate records, you can run the risk of being fined £3,000 by HMRC or even being disqualified as a company director.You should always carefully check all government guidelines on running a limited company to ensure you are fully compliant with the law. How long should I keep company records? You should keep company records for at least six years from the end of the last company financial year they relate to. Records must be kept for longer if:They show a transaction that covers more than one accounting period (i.e. more than one financial year)They relate to a company asset that is expected to last more than six years, such as equipment or machineryThe Company Tax Return was sent lateHMRC has started a compliance check into the Company Tax Return How should I keep payroll and expenses records?As a business owner and employer, it’s your legal responsibility to ensure things like the correct National Insurance Contributions (NICs) — AKA payments that go towards funding state benefits, such as the State Pension, statutory sick pay, and maternity leave — are paid by everyone working in your business. Changes to National Insurance and the Employment Allowance in 2025 From 6 April 2025, the NIC’s Secondary Threshold has been decreased for employers. The threshold has reduced from £9,100 to £5,000 a year. This will be in effect until 5 April 2028.Additionally, the secondary Class 1 NIC rate has increased from 13.8% to 15%. The new measures also include an increase to the maximum Employment Allowance from £5,000 to £10,500. As for expenses, the key is to have a universal system in place for all claims and keep a record for each claim. The simplest way to do so is to draft a standard expenses form and require employees to attach receipts.Expenses are another area where taxes can be complicated:Most expenses incurred personally by company employees are exempt from tax and don’t need to be reported as long as certain criteria are met.However, other expenses, like company cars or private healthcare, do need to be specifically accounted for using the (notoriously tricky) form P11D.For more information, you should consult your accountant and refer to the gov.uk page on expenses and benefits for employers. How do I keep records of my business’s sales and purchases?Keeping an accurate record of sales and purchases can cause a lot of stress. Here are a few handy tips to make this quicker and easier:Use unique invoice numbers for different products/servicesMake sure that you mark all sales or purchases of a particular product or service with a specific invoice number, so you can easily pull up all the sales/purchases of that product or service.For example, someone running a clothing business might use 1234 for sales of white t-shirts, and 4321 for sales of black t-shirts, allowing them to easily access records of each.List your outstanding debtors at year-endAn “outstanding debtor” is a person or company that owes your business money, most often customers who have bought a good or service but have not yet paid for it. It’s really important to keep an up-to-date, accurate list of these by date, so the oldest debts are listed first. It should include:the unique invoice numbers for each transactionthe payment due datethe amount owedthe name of the customerIf you are reasonably certain that a particular invoice won’t be paid (if the company that bought from you has since gone out of business, for example), then mark it as a potential bad debt and explain why. Doing this means your accountant may write it off as a ‘bad’ or ‘doubtful’ debt, which means it could count as an allowable business expense.List your outstanding creditors at year-endAn “outstanding creditor” is a person or company to whom your business owes money, and it’s important to keep track of these, too. The process is the same as for outstanding debtors – organised by date with the oldest debt first, make a list that includes:the unique invoice numbers for each transactionthe payment due datethe name of the supplierthe amount you oweIf you don’t expect to actually pay for a particular purchase (if you received damaged goods, for example), then make a note of this and explain why. Statutory year-end accounts: what are they, and how are they different?Statutory year-end accounts – often known as ‘financial statements’, to differentiate them from the normal accounts you use to run your business – are a mandatory set of financial reports that limited companies must submit at the end of the year. Sole traders and freelancers are not required to submit them.Statutory year-end accounts are not the same as corporation tax returns. While the latter is a report to HMRC showing how much tax your company owes on its profits, statutory year-end accounts differ in two main ways:They are submitted (electronically) to Companies House. Their purpose is to give an overview of your company to anyone searching the Companies House register. In other words, they demonstrate the reliability and solvency of your company. You also must give a copy to any shareholders in your business.Financial statements also have a different deadline from accounts sent to HMRC. They must be submitted within nine months of the end of your company’s financial year.Any company that satisfies the small company criteria set out by HMRC only has to submit an abridged financial statement in the form of a balance sheet signed by a named director (but they must still send full accounts to HMRC). Additionally, all your company members must agree to this.Everyone else, though, will need to submit full accounts. This brings us nicely onto:What do I need to include in my statutory year-end accounts?To start, you’ll need a director’s report, which is a statement written by the company directors that gives an overview of how the business is doing. It should include:A summary of how the business performed throughout the yearThe directors’ view of its current stateHow they expect it to perform in the futureTwo other vital documents that must be included:A balance sheet – This is a record of the total sum (i.e. the financial value) of the company’s assets (the things it owns) and liabilities (the things it owes) at the end of the accounting period (your financial year). It gives a snapshot of your business at a particular time.A profit and loss sheet – This should give a summary of your income and expenses over the previous accounting period, including records of your sales, expenses, tax calculations, and the total amount of profit or loss over the period. It explains how your company performed over the entire financial year.It’s a good idea to include explanatory notes that add further detail so that the figures are given proper context.

So definitely worth checking out! How do I keep records of stock and uncompleted work?Keeping accurate records of stock and unfinished work is an essential part of preparing your year-end accounts. To do so, follow a three-stage process:1. Perform a stocktakeA stocktake means literally counting all the stock your business holds so you can then value it.To minimise disruption, you should plan for this process in advance. Making sure no new stock comes in on stocktake day, for example, will make things much easier, and you can speed up the process by setting aside stock of the same type so it’s easier to count.If you have employees, it’s crucial to have a standard stocktaking procedure in writing so that everyone is on the same page.2. Calculate the total value of your stockThe next step is to work out how much your stock is worth. For tax purposes, you want this value to be as low as possible, so either use the cost you paid for the goods or the price you expect to sell them for – whichever is lower.From there, match the descriptions and names of your goods to the ones used in suppliers’ brochures or price lists, so everything tallies up and there’s no confusion.3. Use the percentage of completion method to calculate the value of unfinished projectsOld, damaged, or unfinished goods should have a corresponding depreciation in recorded value.To work out the value of unfinished projects, you work out how much of the project has been completed, and then use that as a percentage of the total completed value.So, if you’ve completed 50% of the project, then the value would be 50% of the finished value in your year-end accounts.To work out your percentage completion, use time records, costs, or diaries (so make sure these are kept up to date as you work). How do I keep records of fixed assets?A fixed asset is something your business will have for a long period of time (as opposed to stock), such as property (e.g., your business premises), vehicles (a company car or van), and IT equipment (computers, laptops, etc.).Supplying accurate records of these assets is a crucial part of the year-end accounts process.To get started, make a list of all your fixed assets, making sure to record the following information on each:Type of asset – property, vehicles, IT equipment, etc.Purchase datePurchase priceAsset descriptionAsset locationOther information (such as vendor contact details for IT equipment)You should also keep a record of assets disposed of or sold during the previous year.Needless to say, holding on to proofs of purchase is really important when you’re running a business, so make sure you file invoices and receipts in a safe place.Accounting for depreciationDepreciation refers to the way things you buy (assets) lose value as you use them. A common example is the way a new car loses some of its value as soon as you drive it off the forecourt.This also applies to any fixed assets owned by your business, and you’ll need to account for this in your year-end accounts. Make sure to ask your accountant what they think the best strategy would be for your company.How this affects your tax bill is another complex area. Because different companies use different assets for different periods of time, it wouldn’t be fair to simply allow companies to apply set rates of depreciation to offset their tax bill.Instead, fixed assets are governed by capital allowances, which essentially means that you can subtract some or all of the asset’s value from your profits before you pay tax. This works differently for different types of assets. For more information, please see the gov.uk page on claiming capital allowances.Final thoughtsAs you can tell, a lot goes into preparing and submitting your company’s end-of-year accounts. But to narrow it down, there are three golden rules you should follow so that your year-end accounts are fully accurate:Use accounting softwareHire an accountantKeep up-to-date recordsThere’s no doubt that year-end accounts are intimidating, especially for small businesses with little experience in this area. However, a bit of planning and research now will make things go much more smoothly and save you stress at the culmination of your financial year. Startups.co.uk is reader-supported.
