Ask three firms to quote for the same business and the highest figure can be a multiple of the lowest. That gap alarms people, but it is rarely arbitrary: the three firms are almost always pricing three different things. Understanding the sources of variation turns a confusing spread of numbers into a genuine choice between offers.
This guide pairs with our pillar on what an accountant costs a small business, which covers the drivers inside a single quote. Here we explain the differences between quotes.
Different scopes wearing the same name
The biggest source of variation is invisible in the headline: one “accounts and tax” quote includes bookkeeping, VAT, payroll and a director’s return; another covers literally the year-end accounts and nothing else. Both are legitimately priced for their contents. The obligations of running a limited company set a common floor, but everything above that floor is optional scope, and firms bundle it differently. Until you decompose each quote layer by layer (a method set out in what a monthly fee should include), you are comparing labels, not services.
Who actually does your work
Firms have different cost structures and staff models. Work done by a partner-level adviser prices differently from work processed by a junior and reviewed briefly, or offshored, or automated. None of these is automatically wrong (routine processing genuinely does not need senior hands), but you should know which model a quote reflects, and who will pick up the phone when you call. Two questions expose it: who prepares my work, and who reviews it?
Service level: the pace and depth you are buying
Some of the spread is response time and proactivity. A firm that commits to answering within a working day, reviews your position before year end, and warns you about deadlines is running a more expensive operation than one that reacts when you chase. You feel this difference precisely once things get busy or go wrong, which is to say when it matters. Cheap and slow is a real trade; so is fast and thorough. Just make the trade knowingly.
Assumptions about your records
Quotes embed a guess about the state of your books. A firm assuming clean digital records priced low will revise upward when reality arrives; a firm that quotes after seeing your records prices honestly from the start. Since HMRC’s expectations for keeping records are the same for everyone, the variable is you, and the quote that asked more questions about your records is usually the more reliable one, even when it is higher.
Specialisation and risk pricing
Sector knowledge changes fees in both directions. A firm fluent in your industry works faster on your specifics and prices sharper; a generalist may quote higher to cover learning, or lower because they have not seen the complexity coming. Firms also price risk differently. A business with messy history, aggressive positions or looming deadlines will see that reflected unevenly across quotes, because appetite for risk varies by firm.
When the gap really is just price
After normalising all of the above, a residual spread remains: overheads, target margins and how busy the firm is right now. A practice at capacity quotes high without apology; one building its client base quotes keen. This is the one component of variation that is pure negotiation, but you can only see it clearly once the scope, staffing and service differences are stripped out, which is exactly what comparing quotes properly does.
Frequently asked questions
Is the mid-priced quote the safe choice?
Picking the middle number without reading the scopes is still guessing. The middle quote can be the thinnest scope with the plushest office. Rank scopes first, then price.
Why did an online-only firm quote so much less?
Standardised software, standardised processes and no local presence cut cost genuinely. What you give up is tailored advice and a person who knows your business: fine for simple affairs, costly for complicated ones.
Should I tell each firm what the others quoted?
Sharing the scope differences (not just the numbers) is productive: “their price includes payroll, does yours?” forces clarity. Pure price shopping tends to produce trimmed scopes rather than better value.
Do fees vary by region?
Overheads differ by location, so somewhat, though cloud working has flattened this considerably. A local firm’s real premium is availability for face-to-face work; decide whether you use that.
A quote is far below all the others. Trap?
Sometimes it is a genuine capacity-building offer; sometimes it is a teaser that grows through extras. The test is written scope and the firm’s answer to “what would make this fee increase?” Evasion on either is your answer.
