## Short answer

A SaaS PPC agency manages paid acquisition for subscription software and usually charges one of four ways: 10 to 20 percent of media spend, a flat retainer of $3,000 to $15,000 a month, a performance fee tied to qualified opportunities, or a hybrid. The ones worth hiring ask for CRM access on the first call, bid to pipeline rather than form fills, and will agree to a holdout test. Minimum engagements run three to six months because SaaS sales cycles outlast any 30-day trial.

## Key takeaways

- Percentage-of-spend pricing costs 10 to 20 percent of media and only makes sense above roughly $25,000 a month
- An agency that does not ask for CRM access on the first call will optimise to form fills by month two
- Ask how they would measure incrementality on your brand campaign. It is the single most predictive question
- At $8,000 monthly media the agency fee is a quarter to a third of total budget, which usually beats hiring one
- Case studies quoting percentage lifts without absolute numbers are hiding a move from four conversions to sixteen
- Guaranteed lead counts are a promise to buy cheap leads with broad match, and sales will stop taking the meetings

---

Most SaaS teams start shopping for an agency when paid spend crosses about $15,000 a month and nobody internally has the hours to own it. Fair trigger. The trouble is that the shortlist usually arrives from a search that returns lists written by agencies ranking themselves, followed by four pitch decks promising the same 3x return. Fee structure, account staffing and measurement discipline decide how this goes, and only one of those three ever makes it onto a slide.

## What a SaaS PPC agency does that a generalist shop does not

The difference is what they optimise toward. A generalist agency running ecommerce or local services optimises to the conversion event inside the ad platform, because in those businesses that event is a purchase with a value attached to it. In SaaS, the platform conversion is a form fill or a trial start, and the distance between that event and cash is 60 to 180 days of sales cycle.

That distance creates three jobs a generalist rarely does well. First, capturing the GCLID or wbraid parameter on the form and writing it to the CRM record, so a closed-won opportunity in Salesforce or HubSpot can be pushed back into Google Ads as an offline conversion. Second, choosing which downstream event gets the bidding signal: trial start, sales-accepted opportunity, or closed revenue. Third, rebuilding that chain every time the CRM changes shape, which in a growing SaaS company happens roughly twice a year.

Ask a generalist which conversion action they would bid to in month one, before there is enough opportunity volume for smart bidding to learn anything, and you get a fast read on them. A good answer names a proxy event with enough weekly volume, usually 30 or more conversions, and a written plan to migrate the signal once opportunity data accumulates. The mechanics sit in [Google Ads for SaaS](/guides/google-ads-for-saas/) and across the wider [SaaS PPC and paid ads](/saas-ppc/) cluster.

An agency measured on cost per lead will hit your cost per lead target. It will do it with broad match, lead form extensions and a traffic spike from markets you do not sell into, and your AEs will quietly stop taking the meetings by week six.

## The four pricing models and what each one actually costs

There are four, and the right one is a function of your media spend rather than your preference. Percentage of spend, flat retainer, performance or pipeline-based, and hybrid.

Percentage of spend is clean at high volume and punitive below it. At $12,000 a month in media, a 15 percent fee with a $2,500 floor means you pay the floor, which is 21 percent of your budget for an agency that has every incentive to push you past the threshold where the percentage kicks in.

Flat retainer is what I would take at $40,000 a month, with a quarterly scope review and a named strategist written into the contract. It decouples the fee from the budget, which means the agency can recommend a 20 percent cut in September without arguing itself out of income. Ask for the hours behind the number and ask what happens when the account needs more.

Performance pricing sounds like risk transfer and mostly is not. The agency prices the risk into the per-opportunity fee, then optimises for the metric it gets paid on, which is volume of things labelled qualified. If your opportunity stage is set by an SDR who is also compensated on volume, you have built a machine with two people pushing the same lever. Get your target CPA straight first using the [SaaS PPC budget calculator](/calculators/saas-ppc-budget-calculator/), then decide how to pay for the management.

## Which agencies are known for SaaS paid media

Nobody paid to appear here and this is not ranked. What follows is what each shop is publicly known for, so you can build a shortlist that matches your motion rather than one that matches somebody's affiliate agreement.

| Agency | Known for | Usually a fit for |
|---|---|---|
| Directive Consulting | B2B SaaS performance marketing, search and paid social tied to pipeline reporting | Series B and later, $50K+ monthly media |
| Powered by Search | B2B SaaS demand generation with a strong published point of view on measurement | $25K to $150K monthly media, sales-led motion |
| KlientBoost | Paid media paired with in-house landing page and conversion rate work | Teams that need pages and creative as well as media buying |
| Refine Labs | Demand creation weighted toward paid social, self-reported attribution surveys | Higher ACV companies that accept a demand-creation measurement model |
| Obility | B2B search marketing, paid and organic together, long SaaS client history | $10K to $75K monthly media |
| SimpleTiger | SaaS-only, SEO-led with paid search alongside it | Smaller programs where search is the entire plan |
| Kalungi | Full-stack B2B SaaS marketing including fractional CMO, not a paid-only shop | Early companies that need the whole function |
| Tuff | Embedded growth marketing team model for startups | Seed to Series A, budgets under $20K a month |

Fit beats reputation every time. An agency built for $250,000-a-month enterprise ABM will do mediocre work on a $9,000 self-serve account and will not enjoy doing it, and the reverse is just as true. If your motion is product-led with a $40 monthly price point, a shop whose case studies are all six-month enterprise cycles is a bad match no matter how good the deck looks. The channel logic for your motion is covered in [SaaS advertising strategy](/playbooks/saas-advertising-strategy/).

One more thing on shortlisting. Review-site media on G2 and Capterra is frequently managed separately from search and social, sometimes by the agency and sometimes by whoever owns the review programme internally. Decide that before you sign, and read [G2 vs Capterra for SaaS vendors](/comparisons/g2-vs-capterra/) so you know what you are handing over.

## Twelve questions to ask in the pitch

The pitch is where you find out whether they have run a SaaS account or an ecommerce account with a software logo on it. Ask these and listen for specifics rather than philosophy.

**Pitch call diagnostic**

Question five is the one I would keep if I could only ask one. A strong answer describes a geo split or a scheduled brand pause, measured against total branded impressions in Search Console plus direct sessions, with a stated minimum detectable effect and a run length. A weak answer is a version of the sentence you have heard a hundred times: brand always has the best return on ad spend. That sentence is true and meaningless, because the question was whether those conversions would have happened anyway.

- Question one is the other keeper. An agency that does not ask for CRM access on the first call has already told you what it will optimise toward. There is no way to bid on pipeline without reading pipeline, and there is no way to read pipeline from inside Google Ads.

Question three catches the most common disappointment in this category. The people in the pitch are frequently the founders or the head of growth, and the person who touches your account is two years out of university with eleven other accounts. That can still work if the systems are good, but you should know it going in. The full build-versus-buy maths sits in [PPC agency vs in-house for SaaS](/comparisons/ppc-agency-vs-in-house/).

## The red flags that predict a bad engagement

Five things in a pitch correlate strongly with a wasted six months. None of them are subtle once you know to watch for them.

Guaranteed lead counts come first. A promise of 40 MQLs a month is a promise to hit a number, and the cheapest route to any lead number is broad match plus a lead form extension plus loose geo settings. The agency keeps its guarantee and you get a pipeline of students, job seekers and agencies from markets you do not serve. Check [SaaS PPC mistakes that waste budget](/guides/saas-ppc-mistakes/) for the rest of that pattern.

Case studies built on percentage lifts with no absolute numbers are second. A 312 percent increase in conversions is four to sixteen. Ask for the starting number, the spend, and the revenue outcome. If the answer is that the client will not let them share it, ask for a redacted version with the shape intact.

Any agency that refuses a geo holdout or a scheduled brand pause is telling you it does not want its work measured against a counterfactual. That is the whole point of the test. Refusal is not a scheduling problem, it is a position.

Two more. A twelve-month contract with a 90-day notice period, in a channel where you can read directional quality in eight weeks, is a pricing decision dressed as a commitment. And reporting that lives only in the agency's own dashboard, rather than in your CRM or a Looker Studio view you own, means you lose the history when the relationship ends.

## What it costs at four spend levels

Total budget is media plus fee, and the fee ratio is what decides whether the arrangement makes sense. Here is the shape at four common levels.

| Monthly media | Likely fee | All-in monthly | Fee as share of total | What you should get |
|---|---|---|---|---|
| $8,000 | $2,500 to $4,000 flat | $10,500 to $12,000 | 24% to 33% | One channel run properly, almost certainly Google Search only |
| $25,000 | $5,000 to $8,000 flat | $30,000 to $33,000 | 17% to 24% | Search plus one secondary channel, landing pages, monthly offline import |
| $80,000 | 12% to 15% of spend, or $10,000 to $15,000 flat | $90,000 to $95,000 | 11% to 16% | Full channel mix, named strategist, creative production, quarterly test roadmap |
| $250,000 | 8% to 12% of spend | $270,000 to $280,000 | 7% to 11% | Dedicated pod, in-platform ABM, incrementality testing as standard practice |

The $8,000 row is the argument against hiring an agency at all, written as a number. A quarter to a third of your paid budget going to management is defensible when the manager is unlocking channels you could not run yourself, and indefensible when the work is one Search campaign and a fortnightly report. Split the budget properly first using [SaaS PPC budget allocation](/guides/saas-ppc-budget-allocation/), because the allocation decision changes which agency you need.

## When not to hire an agency at all

Four situations where hiring one is the wrong call, and I would say the first two account for most of the regret in this category.

Spend under about $8,000 a month is the first. The fee ratio breaks, and there is not enough data volume for anyone to do clever work. Hire a freelancer for 10 to 15 hours a month at $2,000 to $4,000, or a fractional paid media lead at $4,000 to $7,000 who also builds the measurement layer you will need later.

An unproven offer is the second. If your demo page converts at 0.4 percent from organic and outbound, paid traffic will convert worse, because it is colder. No agency fixes a positioning problem with a bid adjustment. Get the page and the offer working on traffic you already have, then buy more of it.

Then there are two operational ones. If nobody internally can give the relationship three hours a week, including a real decision on scope and budget, the engagement drifts into monthly reporting theatre. And if your CRM stages are unreliable, an agency will spend its first quarter optimising to form fills while you pay it to optimise to pipeline. Fix the stage definitions first. [SaaS performance marketing](/guides/saas-performance-marketing/) covers the measurement chain you need in place before anyone external touches the account.

Before the agency search, spend $1,500 on a paid audit from two shops on your shortlist. You get two independent reads on your account, a working sample of their thinking, and a much better sense of who you would tolerate on a Thursday afternoon call.

## How to run the selection in three weeks

Compressing this is fine. Dragging it over two months is not, because the account keeps burning money at the current efficiency the entire time.

**A three-week agency selection**

Start with the brief this week. Take the ad copy foundations from the [SaaS ad copy swipe file](/templates/saas-ad-copy-swipe-file/) so you can judge what any agency produces against a baseline, and read [digital advertising for SaaS companies](/guides/digital-advertising-for-saas/) before the first call so you are buying a plan rather than a personality.

## Frequently asked questions

### How much does a SaaS PPC agency cost per month?

Flat retainers commonly run $3,000 to $15,000 a month depending on channel count and market coverage. Percentage-of-spend deals sit at 10 to 20 percent of media, often with a floor around $2,500. Performance-weighted deals pair a smaller base with a fee per qualified opportunity. Expect the fee to represent 10 to 15 percent of total budget at healthy spend levels.

### Should a SaaS company hire a PPC agency or build in-house?

Below about $15,000 a month in media, a freelancer or a fractional paid media lead at $2,000 to $6,000 a month is usually better value than an agency. Between $15,000 and $150,000 an agency wins on channel breadth and creative throughput. Above that, an in-house buyer with agency support on specialist channels tends to cost less per opportunity.

### What is the minimum ad spend a SaaS PPC agency will work with?

Most SaaS-focused shops set a floor between $10,000 and $25,000 a month in media, and a few enterprise-oriented agencies will not engage below $50,000. Agencies with lower floors typically run a pooled account manager model where your account gets four to eight hours a month. Ask for the hours figure in writing.

### How long before a SaaS PPC agency shows results?

Expect two to four weeks for account restructure and tracking work, six to eight weeks for the first honest read on cost per qualified lead, and a full sales cycle, often 60 to 180 days, before closed-won data can validate anything. Judge month three on lead quality trend and measurement hygiene, not on revenue.

### What questions should I ask a PPC agency in the pitch?

Ask how they import offline conversions from your CRM, which downstream event they bid to, who manages the account day to day and what else that person runs, how they would measure incrementality on brand search, and whether they will agree to a geo holdout test in the first six months. Specific answers separate operators from account managers.

### Do SaaS PPC agencies work on performance-based pricing?

Some do, usually as a reduced base retainer plus a fee per sales-qualified opportunity or a share of sourced pipeline. It only works when both sides agree the qualification definition in writing before signing, and when your CRM records that stage reliably. Otherwise every monthly call becomes an argument about which leads counted.

### How do I know if my PPC agency is doing a good job?

Look at cost per sales-accepted opportunity over a rolling 90 days, not cost per lead. Check that the search terms report is reviewed at least fortnightly, that offline conversions are importing without errors, and that they have recommended cutting or pausing something in the last quarter. Agencies that only ever recommend more spend are managing their own revenue.
