When you review accounting proposals, the headline monthly fee is rarely the most useful number on the page. Firms package their services differently, so one quote may include bookkeeping, payroll and regular advice, while another may cover little more than year-end compliance. Neither is automatically better or worse. The question is whether you know which is which.

Comparing accounting proposals properly means looking at the services included, identifying exclusions, checking who is responsible for each filing, and calculating a realistic annual cost before you weigh up the broader value of the relationship. This post works through each of those steps in turn.

A good proposal should leave very little room for guesswork. It should explain the work being provided, how frequently it will be completed, and which responsibilities remain with you. Before comparing prices at all, you should establish whether each firm is quoting for broadly the same work.

Core services to look for

The proposal should make clear which services are included, rather than relying on broad descriptions such as "full accounting support". For a limited company, the scope might cover:

• Statutory annual accounts
• Corporation Tax calculations and returns
• Bookkeeping
• VAT returns
• Payroll
• Director Self Assessment returns, where required
• Companies House filings
• Management accounts
• Ongoing accounting or tax queries

Your business may not need every item on that list. What matters is knowing which are included before you compare one quote with another. A proposal covering limited company accounts may include statutory accounts and Corporation Tax work, while bookkeeping, payroll or management reporting sit elsewhere in the package. A lower quote can therefore simply reflect a narrower scope.

Who is responsible for each filing?

You should check not only whether work is prepared, but also whether the accountant will submit it. There is a practical difference between preparing figures for your approval and taking responsibility for completing the relevant submission once your approval and information have been received. Look for clear wording around statutory accounts, Corporation Tax returns, VAT returns, payroll submissions and Companies House work. You also need to understand what the accountant requires from you and when — even when a firm handles a filing, timely and accurate records still need to come from your side.

How often will bookkeeping actually be updated?

Bookkeeping frequency can make a substantial difference to what a service provides during the year. Annual bookkeeping may be enough to produce year-end accounts, but it gives a very different level of visibility from monthly or regular bookkeeping. With ongoing bookkeeping services, records can be reconciled and maintained throughout the year, making it easier to review cash flow, VAT, profitability and upcoming liabilities using current figures. When comparing proposals, check whether bookkeeping is completed monthly or quarterly, brought up to date only before a filing deadline, or excluded entirely.

You should read the exclusions just as carefully as the list of included services. A fixed fee can still be built on assumptions about transaction volumes, employee numbers, VAT requirements or the amount of work involved. If those assumptions change, the fee may change too. That is reasonable — provided it is clear from the outset.

Transaction volumes, employees, and VAT

Some proposals are priced around expected activity levels. A bookkeeping package may assume a certain number of transactions or bank accounts; a payroll package may cover a particular headcount. Additional VAT registrations, currencies or trading entities can also affect scope. The useful question is not simply, "Is this a fixed fee?" It is, "What assumptions is this fixed fee based on?"

Questions and meetings — included or charged separately?

Access to advice varies considerably between firms. One proposal may include routine calls and questions throughout the year; another may include an annual meeting but charge separately for additional advisory work. Neither approach is necessarily unsuitable, but you need to know what you are comparing. You should clarify how routine questions are handled, whether meetings are included, whether there are limits on advisory time, what counts as additional tax planning, and how separate project work is priced. If your business rarely needs advice, a compliance-focused service may be sufficient. If it involves frequent decisions about staff, investment, cash flow or remuneration, access to ongoing advice is likely to matter more.

Software costs

Software can create another difference between apparently similar proposals. Confirm whether subscriptions for platforms such as Xero or QuickBooks are included in the fee, charged separately, or paid directly by your business. Check whether the proposal includes setup, migration, bank-feed connections, integrations and ongoing support. A £20 or £30 monthly difference between two quotes can look meaningful until separate software and administration costs are added back in.

Onboarding and catch-up work

Switching accountants does not always mean starting with perfectly organised records. There may be overdue bookkeeping, unreconciled transactions, missing information or work needed to move data from an existing system. Ask whether any catch-up work is included in the ongoing fee or quoted separately. A clear proposal should separate recurring charges from one-off costs so you can calculate the first-year cost accurately.

Price becomes much less important if an essential filing or service has been left out. You should compare each proposal against the actual compliance responsibilities of your business, rather than assuming that every accounting package covers them automatically.

Limited company deadlines

For most established private limited companies, annual accounts are generally due at Companies House nine months after the financial year ends. Corporation Tax is normally payable nine months and one day after the relevant accounting period ends, while the Company Tax Return is generally due twelve months after the accounting period ends. The rules can differ for first accounts and particular circumstances, so check the relevant dates rather than working from a general rule. The current GOV.UK guidance on limited company accounts and tax returns sets out the main deadlines. When comparing proposals, establish which of these responsibilities the accountant will monitor and handle, and which remain for you to complete separately.

Confirmation statements and Companies House work

A proposal that refers to "Companies House compliance" should make clear what that means. Ask specifically whether confirmation statement work is included, whether the filing fee is separate, and whether changes to company information during the year attract additional charges. This avoids assuming that every Companies House requirement is covered simply because annual accounts are included.

Making Tax Digital for Income Tax

Making Tax Digital for Income Tax began applying from 6 April 2026 to qualifying sole traders and landlords with more than £50,000 of qualifying self-employment and property income based on the relevant earlier tax return. The rollout continues to qualifying income above £30,000 from April 2027 and above £20,000 from April 2028. HMRC's current Making Tax Digital for Income Tax guidance explains the thresholds, digital record requirements and quarterly updates. Where these rules apply, check whether compatible software, record keeping, quarterly updates and the year-end tax return are included in the proposal.

Who is responsible if something is filed late?

An accountant can manage deadlines and prepare submissions, but the relationship works properly only when responsibilities are clear on both sides. You need to know when records must be supplied, who approves filings, and what happens if information is incomplete or delayed. Look beyond the promise to "handle compliance" and understand the process used to request information, monitor deadlines and obtain approval.

Price matters, particularly when you are managing cash carefully. You should not ignore it. But you should compare it against the amount and usefulness of the service received. A cheaper package can represent excellent value where your business needs straightforward compliance. A more comprehensive package may make more sense where regular bookkeeping, reporting and advice are genuinely useful.

Calculate the true annual cost

The simplest way to compare quotes is to convert everything into an estimated annual figure. Include:

• Core monthly or annual fees
• Software subscriptions
• Payroll charges
• VAT work
• Additional tax returns
• Expected meetings or advisory work
• Onboarding or catch-up fees
• Any predictable add-ons

That prevents a low base fee from appearing cheaper when routine extras make the actual annual cost similar to, or higher than, another proposal. A comparison table can help here — mapping each firm against the same list of line items, from statutory accounts and bookkeeping frequency through to software, transaction limits and onboarding fees, with an estimated annual total at the bottom.

Will you get useful financial information before year-end?

Accounts prepared once a year are primarily backward-looking. For some businesses, that is enough. Others need more regular information about margins, cash flow, spending or tax liabilities. If management accounts or regular reporting are included in one proposal but absent from another, the two packages are not equivalent simply because both contain annual accounts. The value depends on whether you will actually use that information to run your business.

Compliance only, or ongoing advice as well?

Compliance helps you meet filing and reporting obligations. Advisory support may involve interpreting the numbers, planning for tax liabilities, reviewing performance or discussing the financial implications of business decisions. If your business has stable operations, you may need relatively little ongoing advice. If it is growing or changing, more regular input may be worth paying for. The point is to pay for the level of support that is useful, not to choose extra services because they look impressive in a proposal.

Responsiveness and continuity

Responsiveness can be difficult to value until an urgent question arises. Ask who the main contact will be, how queries are normally handled, and whether the proposal gives any indication of expected response times. Consider whether the service gives you access to someone familiar with your business, rather than requiring every question to start from the beginning.

Once you have compared scope, exclusions, compliance and cost, consider how well the service fits the way your business is likely to operate over the next few years. The aim is not to buy every possible accounting service in advance. It is to avoid choosing a package that already looks too limited for foreseeable needs.

Changes your business might face

Think about what is likely to change: increasing turnover, VAT registration, hiring employees, adding directors or shareholders, seeking finance, opening another business entity, requiring management reporting, or needing more regular tax or commercial advice. Then ask how easily the proposal can adapt to those changes. A proposal does not need to predict every future scenario, but it should explain how scope and fees are reviewed when the underlying workload shifts.

How much financial visibility do you actually want?

Different businesses want different relationships with their accountants. You may mainly want accurate records, annual accounts and tax returns completed properly. Or you may want monthly figures, cash-flow visibility and regular conversations about performance. Being clear about which type of relationship you require makes comparing proposals considerably easier, and helps you avoid paying for support you will not use.

Ten things to confirm in writing before signing

1. Exactly which services are included
2. How frequently each service is completed
3. Which services are excluded
4. The fixed or variable fee structure
5. Any usage or transaction limits
6. Which software costs are included
7. How additional work is approved and priced
8. What information you need to provide, and when
9. How communication and meetings are handled
10. What notice or termination arrangements apply

If these points are clear before you sign, there should be far fewer surprises later. You should also check the engagement terms around notice periods, payment arrangements, responsibility for outstanding work, and the process for handing records to a new adviser if the relationship ends.
