How much should an accounting firm spend on marketing?

A small firm trying to grow beyond word-of-mouth can start close to the floor: Google Ads near the $600 management minimum plus enough spend to compete on "accountant near me" and service-specific searches like bookkeeping or business tax help, since a thin budget can still fill a handful of new-client conversations each month.

A firm building a genuine recurring client base typically settles into $1,800 to $3,500 a month, combining ad spend targeted at higher-value services like bookkeeping and advisory with an SEO program past the 10-page floor that builds authority on the services the firm actually wants more of.

A growing multi-partner firm, or one deliberately shifting away from seasonal 1040 work toward year-round advisory clients, often needs $4,000 or more a month, since building demand for a service that isn't tied to a tax deadline requires more sustained content and campaign investment than seasonal work does.

Google Ads management is 10% of your spend, floored at $600 CAD or $450 USD a month, with nothing marked up on the media dollars. For a firm, this channel works best aimed at the services worth the most over time, bookkeeping, payroll, and advisory, rather than broad tax-season traffic that produces mostly one-off filers.

SEO is $50 CAD or $38 USD per page starting at 10 pages a month. For a firm, that typically means dedicated pages for bookkeeping, payroll, and business advisory services, content that builds trust in your credentials, and pages answering the questions business owners research before choosing who to trust with their finances. It builds slower than ads but produces client conversations you're not paying per click for.

A website is a separate one-time cost, from $1,500 to $20,000 and up. For most firms, the deciding factor is whether the site needs online scheduling and clear service breakdowns for bookkeeping and advisory work, or whether a simpler, credible site with a contact form is enough while the firm is still growing that side of the business.

LocaliQ and WordStream's 2026 Search Advertising Benchmarks report puts Business Services, the category accounting firms fall under, at a $93.69 average cost per lead and a 4.85% conversion rate on Google Ads. This spans many kinds of professional services beyond accounting, so it's a directional figure rather than an exact number for your firm's specialty.

Use it to check whether a proposal is reasonable rather than to expect it precisely. If a quoted cost per lead runs far above roughly $94 for a well-targeted campaign around bookkeeping or advisory services with no explanation, ask what's driving it. A tightly focused campaign for one high-value service in a smaller market can beat that average; a broad "accountant near me" campaign in a large, competitive city can run above it.

Seasonality has an outsized effect on this business, since the phone often rings hard in tax season and goes quiet by early summer. A firm that builds year-round demand for advisory and bookkeeping work through SEO and steady content tends to smooth that swing out better than one that only markets around the filing deadline.

Referral dependence is worth watching too, since word-of-mouth can't be scaled or controlled, and when a key referral source retires or moves on, growth can stall abruptly. A firm with an active marketing system running alongside referrals has a backup channel that keeps producing new client conversations regardless of what happens to any single relationship.

What service mix you're chasing changes the priority. A firm mostly wanting more once-a-year tax clients doesn't need the same investment as one trying to build a book of monthly bookkeeping and advisory retainers, since the second is worth several times more over the life of the client relationship. There's no setup fee, plans run month to month, and the first 30 days carry a guarantee: if you're not satisfied, you don't pay.
