Most accountants have the same story about marketing agencies. A monthly retainer that felt reasonable. Three or six months of "building the brand" and "growing awareness". A folder of reports full of impressions and reach. And, at the end of it, not one new client they could point to. The retainer was not the real cost. The real cost was half a year of standing still while a competitor down the road got chosen instead.
Choosing the right marketing partner is one of the highest-leverage decisions a practice makes, and one of the easiest to get wrong. This is a buyer's guide to getting it right: the types of agency that serve accountants, the channels a full-service partner should actually cover, the five things that separate a great partner from an expensive one, the questions to ask before you sign, the red flags that should end a conversation, what you should expect to pay in 2026, and a simple 30-day way to test any agency before you commit.
Why the wrong agency costs more than the retainer
A marketing engagement has two prices. The visible one is the monthly fee. The invisible one, which is almost always larger, is the opportunity cost of the clients you did not win while nothing was working. If a retained accountancy client is worth over €10,000 in lifetime value, then an agency that costs you six months and delivers nothing has not cost you its fee. It has cost you the three or four clients you should have won in that time, plus the fee.
That is why "cheap" and "expensive" are the wrong lens. The only question that matters is whether the partner reliably produces booked calls with clients you want, at a cost that makes sense against what a client is worth. Everything below is about telling, in advance, whether they will.
The four types of provider serving accountants
Not every provider is an agency, and not every agency is right for a practice. There are four broad types.
| Type | What they are | Best for | Watch out for |
|---|---|---|---|
| Generalist agency | Markets any business, from cafés to clinics | Practices wanting broad reach, big budgets | No grasp of accountancy or compliance |
| Specialist agency | Works only with accountants or finance firms | Practices wanting sector expertise | Higher fees, waitlists |
| Freelancer | One person doing one channel | A single specific task | Limited scope, key-person risk |
| Done-for-you system | A platform plus a team, run for you | Practices wanting the whole system handled | Check it is genuinely done for you |
The generalist can run a competent Facebook campaign but will not know why "switching accountants" is a high-intent search or why you cannot promise a tax outcome. The specialist knows your world but often costs more and picks its clients. The freelancer is excellent for one job and fragile as a whole solution. The done-for-you system handles everything under one roof, which suits a busy practice, provided it truly runs for you rather than handing you software and a login.
The channels a full-service partner should cover
One of the most common ways a practice gets burned is hiring a provider who is really a one-channel shop dressed up as a full-service agency. You pay for "marketing" and get, in practice, one lever pulled in isolation. A partner that can actually grow a firm understands that different channels do different jobs on different timelines, and it sets your expectations honestly about which is which.
The single most useful distinction to hold in your head is immediate versus long-term. Some channels can put you in front of a ready-to-switch business owner this week, but stop the moment you stop paying. Others take months to build but keep compounding long after the work is done, and cost nothing per enquiry once they are working. A good partner runs both at once: the immediate channels buy you enquiries while the long-term ones are still warming up, and the long-term ones eventually lower your reliance on paid clicks. Anyone who tells you a single channel is all you need is either inexperienced or selling the only thing they can do.
| Channel | Timeline | What it does for a practice | What to keep in mind |
|---|---|---|---|
| SEO and content | Long-term, compounding | Wins the high-intent local searches ("accountant near me", "switch accountants") and builds authority that keeps paying off | Takes typically 3 to 6 months to move; the earlier you start, the cheaper every future enquiry becomes |
| Paid search (PPC) | Immediate | Puts you at the top of Google for buying-intent searches from day one | Stops the moment the budget stops; costs per click in finance can be high, so it needs tight management |
| Paid social | Immediate | Builds awareness and retargets visitors who did not enquire the first time | Lower intent than search; better for staying visible than for capturing someone actively looking |
| Conversion rate optimisation (CRO) | Immediate to medium | Turns the traffic you already have into more enquiries by fixing the website and the follow-up | The cheapest growth of all, because you are not paying for more visitors; widely ignored |
| Email marketing | Medium-term | Nurtures leads who were not ready yet and keeps you in front of existing clients for cross-sell | Needs a list and a reason to write; low cost, high return when done consistently |
| PR and digital PR | Long-term | Earns trusted mentions and links that lift both credibility and SEO | Slower and harder to attribute; valuable for authority, not for this week's enquiries |
| Social (organic) | Long-term | Signals that you are active and human, and gives referrals somewhere to check you out | Rarely a direct lead source for accountants; a supporting act, not the headline |
You do not need every channel firing at once, and a good partner will not sell you that. What you need is a sensible mix: at least one immediate channel so enquiries start moving, at least one long-term channel so the cost of those enquiries keeps falling, and a relentless focus on conversion so none of the traffic you paid for is wasted. The mistake to avoid is paying premium prices for long-term channels alone and then wondering, three months in, why the phone has not rung.
Conversion rate optimisation: the lever most agencies ignore
Of all the channels above, the one worth pausing on is the one almost nobody sells: conversion rate optimisation. It deserves its own section precisely because it is so overlooked, and because it is usually the fastest, cheapest growth available to a practice that already gets some traffic.
Here is the logic. Most agencies make their money by sending you more visitors, whether through ads or SEO. More traffic means bigger budgets and bigger retainers, so that is where their attention goes. But traffic is only half the equation. If a hundred people visit your website this month and two enquire, you have a two percent conversion rate. Double that to four percent and you have doubled your enquiries without spending a penny more on getting people to the site. That is CRO, and for most practices it is sitting there untapped.
The reason it gets ignored is that it is unglamorous and it does not scale the agency's invoice. It means fixing dull, decisive things: a homepage that does not say within five seconds what you do and who for, a contact form buried three clicks deep, a phone number that is not clickable on mobile, no clear reason to choose you over the firm next door, and above all slow or absent follow-up when an enquiry comes in. Responding to a new enquiry within minutes rather than hours typically increases the odds of winning that client, yet most practices take a day or more.
A partner that takes CRO seriously will look at your enquiries won per hundred visitors before it ever suggests spending more on traffic. If someone wants to sell you ads without first asking whether your site and your follow-up can convert the clicks they send, they are optimising for their invoice, not your growth. Ask any prospective agency what they would do to improve your conversion rate, not just your traffic. The quality of the answer tells you a great deal.
Why sector and compliance expertise matters
It is tempting to think marketing is marketing, and that a good generalist can learn your world quickly enough. In accountancy specifically, that assumption is expensive, for two reasons: what a specialist already knows, and what a generalist is legally liable to get wrong.
Start with what a specialist already knows. An agency that works only with accountants does not have to learn your market on your budget. It already knows that "switching accountants" and "fixed fee accountant" are high-intent searches worth far more than a generic "accountant" impression. It already knows your calendar: the self-assessment deadline in January, the run-up to year-end, the Making Tax Digital changes pushing businesses to look for a more capable firm, the quiet months when a nurture campaign lands best. It knows which trust signals actually convince a business owner to hand over their books: professional-body membership, real reviews, clear fixed pricing, a human face rather than stock photos of skyscrapers. A generalist has to discover all of this by trial and error, and you are the one paying for the lessons.
Then there is compliance, where the cost of a generalist is not just slower results but genuine risk. Accountancy marketing sits inside rules a café or a gym never has to think about. You cannot promise specific tax savings or guarantee an outcome. If you give regulated advice, financial-promotion rules apply to how you word things. Your professional body (whether ACCA, ICAEW, Chartered Accountants Ireland or another) has expectations about how you present yourself. Client confidentiality means you cannot splash names and numbers across a case study without permission, and review-gating can breach platform and body rules. A generalist agency, chasing a punchy headline, will happily write "we guarantee to cut your tax bill" and never know it just exposed you. A specialist raises these issues before you have to, because it has seen them before.
This is the single clearest reason to lean towards a specialist agency or a done-for-you system built for accountancy. Not because generalists are bad at marketing, but because in your sector the gap between someone who knows the terrain and someone learning it is measured in both wasted months and compliance exposure.
The five-factor evaluation framework
Score any provider against these five factors. A great partner is strong on all five; an expensive one is usually weak on three.
Factor 1: Track record with accountancy practices
Have they actually grown firms like yours, in Ireland or the UK, and can they show it? Sector experience is not a nice-to-have. An agency that understands accountancy already knows the searches your clients use, the seasons that matter, and the trust signals that convert. Ask for specific examples of practices they have helped and what changed.
Factor 2: Compliance understanding
Your marketing has to satisfy your professional body and, if you advise, financial-promotion rules. A partner who does not know that you cannot promise specific tax savings, cannot gate reviews, and must keep client details confidential is a liability, not an asset. The right partner raises compliance before you have to.
Factor 3: Pricing that aligns incentives
The pricing model tells you whose interest the agency serves. A flat fee for a defined system is honest and predictable. A percentage of ad spend quietly rewards them for spending more of your money. A long lock-in with no performance link protects them, not you. Look for pricing that is transparent, predictable, and tied to work you can see.
Factor 4: Honest reporting and attribution
You should get a plain-English answer every month to one question: what did I get for this? Reporting built on impressions, reach and "engagement" is designed to look busy. Reporting built on enquiries, booked calls, clients won and cost per client is designed to be useful. If you cannot tell from the report whether it is working, it is the wrong report.
Factor 5: Willingness to share risk
The clearest signal of confidence is a partner willing to put something on the line: no long contract, month to month, kept by results rather than clauses. An agency certain it can deliver does not need to trap you. One that insists on a twelve-month lock-in is telling you how it retains clients, and it is not by performance.
An agency confident it can deliver does not need to lock you in. The length of the contract they push is usually inversely proportional to their confidence in the results.
The questions to ask before you hire
Interviewing an agency is like interviewing a hire, because that is effectively what it is. The point of the questions below is not to catch anyone out. It is to hear the difference between a partner who thinks in terms of clients won and one who thinks in terms of activity billed. Use this as a checklist. For each question you will hear either the answer of a confident specialist or the answer of someone hoping you will not look too closely.
| Question to ask | What a good answer sounds like | Red-flag answer |
|---|---|---|
| Can you show me accountancy firms you have grown? | Specific examples, in your region, with what actually changed (enquiries, clients, cost per client) | Vague name-drops, generic "clients across many sectors", or nothing they can show |
| How do you handle our compliance obligations? | Raises financial-promotion rules, review-gating, confidentiality and no-guarantee language unprompted | "That is your side to worry about" or a blank look |
| Which channels would you run, and why those? | A mix of immediate and long-term, matched to your goals, with honest timelines | One channel for everything, or every channel at once with no reasoning |
| What would you do to improve our conversion, not just our traffic? | Talks about the website, the enquiry form, and follow-up speed before talking about spend | Only talks about sending more visitors |
| How exactly do you price, and is there a contract? | A clear number, a clear model, and month-to-month or short-term terms | "It depends, let's talk" that never becomes a figure, or a long compulsory lock-in |
| What does reporting look like, and can I see a real example? | A plain-English report led by enquiries and clients won, shown to you upfront | Impressions, reach and followers, with no line for clients |
| What happens in the first 90 days, and what does success look like? | A concrete plan with numbers you can hold them to | Awareness, brand building, and no measurable target |
| What happens if it is not working? | A straight answer about reviewing, adjusting, and being able to leave | Deflection, or "these things take time" as a catch-all |
If a provider is confident and honest, this conversation is easy for them and reassuring for you. If it is hard work, that is your answer before you have spent anything.
Understanding pricing models: what each one incentivises
How an agency charges is not just an admin detail. It quietly shapes what they will do all year, because every pricing model rewards a different behaviour. Two agencies charging roughly the same amount can be pulling in opposite directions depending on how that money is structured. Before you compare numbers, understand what each model is nudging your partner to do.
| Pricing model | How it works | What it incentivises | Best for |
|---|---|---|---|
| Monthly retainer | A fixed fee for an agreed scope of ongoing work | Consistency, but can drift into "keeping busy" if scope is loose and results are not tracked | Practices wanting a steady partner, provided reporting stays honest |
| Project fee | A one-off price for a defined piece of work | Delivering that specific thing well, but no ongoing accountability for results afterwards | A single job, like a new website, with a clear start and end |
| Percentage of ad spend | The agency takes a cut of what you spend on ads | Spending more of your money, whether or not more spend is the right call | Rarely ideal for a practice; the incentive points the wrong way |
| Flat productised fee | One transparent price for a defined, repeatable system, run for you | Efficiency and results, because their margin depends on getting you outcomes, not on inflating spend | Busy practices wanting predictability and aligned incentives |
The percentage-of-spend model deserves particular caution. It sounds fair until you notice that the agency earns more the more of your budget it burns, regardless of whether the extra spend produces a single extra client. Their incentive and yours are quietly opposed. A retainer is better, but only as good as the reporting behind it, because a loose retainer with no results tracking can reward activity for its own sake. A project fee is honest for one-off work but leaves nobody accountable for what happens next. The flat productised fee tends to align interests most cleanly: the price is fixed and transparent, so the only way the provider profits is by working efficiently and keeping you long enough that you are clearly getting value. Whichever model you choose, ask yourself the same question: what does this structure reward my partner for doing when I am not watching?
Red flags: walk away if you see these
- A guarantee of a specific Google ranking or position. No honest provider can promise this; the algorithm is not theirs to command.
- Hidden or "it depends, let's talk" pricing that never becomes a number.
- Reports full of impressions, reach and followers, with no line for clients won.
- A long compulsory contract with no performance link.
- No understanding of, or interest in, your compliance obligations.
- Vague promises of "awareness" and "brand building" with no path to booked calls.
- A one-channel shop selling itself as full-service, or an eagerness to spend on ads before ever asking whether your site and follow-up can convert the clicks.
What to expect to pay in 2026
Prices vary by scope and by provider type. These are typical monthly ranges for accountancy practices in Ireland and the UK, so you can spot both the overpriced and the too-good-to-be-true.
| Provider type | Typical monthly cost | What it usually includes |
|---|---|---|
| Freelancer (one channel) | €300 to €900 | A single service, such as ads or SEO |
| Generalist agency | €1,000 to €3,000+ | Multiple channels, plus management fees |
| Specialist agency | €1,500 to €4,000+ | Sector expertise, often plus a setup fee |
| Done-for-you system | €500 to €1,500 | The whole system, run for you, one fee |
The cheapest option is rarely the best value and the most expensive is rarely the safest. Value is clients won per euro spent, not the size of the invoice. Note too that these figures usually sit on top of any advertising budget: if a channel needs paid clicks, the ad spend itself is a separate cost that goes to Google or Meta, not to the agency. A transparent partner will always separate its fee from your media spend so you can see exactly where each euro goes.
Run a 30-day evaluation before you commit
You do not have to guess. Test any provider with a simple, low-risk 30-day process.
- Ask for a free, honest assessment of where you stand now: your visibility, your top local competitor, and the gap. A confident partner gives you this before you pay anything.
- Ask exactly what they would do in the first 90 days, in plain English, and what success looks like in numbers.
- Ask how they price, whether there is a contract, and what happens if it does not work.
- Ask to see reporting from a real client, with the vanity metrics stripped out.
If a provider is reluctant on any of these, you have your answer. The right partner is transparent because transparency is in their interest too.
The case for a specialist, done-for-you partner
For most busy practices, the best fit is a done-for-you system built for accountancy specifically. It removes the two biggest problems at once: the generalist's lack of sector understanding, and the freelancer's fragmentation. One team that knows accountancy, one platform running the whole system across the channels that matter, one plain-English report, and pricing that does not punish you for growing.
That is exactly what Webnua is. It is built for accountancy and finance practices only, run for you for one flat monthly fee, with no contract and nothing published without your approval. You get the whole system (website, local SEO, Google Business Profile, reviews, follow-up, content and reporting) from one team that works with practices like yours all day. Because the fee is a flat productised price rather than a cut of your ad spend, the only way it profits is by getting you results and keeping you long enough that the value is obvious. If you want the detail on how that works day to day, see our guides on done-for-you marketing for accountants and how a done-for-you system compares to hiring a marketing manager.
And it starts the way this guide says every good partner should: with a free 15-minute Visibility Audit that shows you exactly where you stand, what your top competitor is doing, and a plan to overtake them. Useful whether or not you ever work with us, and no pitch unless you ask for one.
