Key Takeaways for B2B SaaS Marketing Leaders
- Traditional B2B agencies often use percentage-of-spend billing and long contracts that misalign incentives with SaaS revenue goals.
- Flat monthly retainers and month-to-month terms better match the needs of Series B companies focused on CAC efficiency and flexibility.
- Net New ARR reporting connected directly to CRM data supports board-level accountability better than vanity metrics like impressions or MQLs.
- Directive Consulting offers strong execution but includes percentage-of-spend fees and longer contracts, which limit flexibility for scaling teams.
- Explore a flat-retainer, month-to-month alternative that reports closed-won Net New ARR.
The Problem: Why Traditional B2B Agency Models Fail SaaS Leaders
Most B2B marketing agencies serving SaaS companies are structurally misaligned with the outcomes their clients need. Three failure modes recur across the industry.
Percentage-of-spend billing inflates budgets. Paid media management fees billed as a percentage of spend typically run 10–20% of monthly ad spend. When agency revenue scales with client spend rather than with pipeline, the agency is financially incentivized to recommend higher budgets regardless of efficiency. As one agency founder put it, “When you ask the agency to kill a wasteful campaign, you are asking them to reduce their own fee.”
Long contracts shift all risk to the client. Percentage-of-spend contracts often involve multi-month commitments, notice periods, and termination requirements that shift risk to the client. The agency enjoys predictable revenue while the client carries the performance risk.
Vanity metrics obscure CAC reality. The median new-CAC ratio for B2B SaaS reached $2 spent for every $1 of new ARR in 2026. Agencies that report clicks and CTR instead of pipeline and CAC payback leave VPs of Marketing unable to defend spend at the board level.
How Much Does a B2B Agency Typically Cost?
Understanding how agencies structure their fees helps you see whether their pricing model supports your efficiency goals or works against them. Pricing varies widely by billing model, agency tier, and scope. The ranges below reflect 2026 market data.
Flat monthly retainers are the most common structure. Typical retainers vary by company size and services. Mid-market B2B marketing agency retainers run $10,000–$25,000 per month, with the broader market spanning $5,000–$50,000+, and enterprise demand generation partnerships routinely exceeding $50,000 per month.
Percentage-of-spend fees add a variable layer on top of or in place of retainers. HawkSEM’s 2026 PPC pricing guide confirms the 10–20% range cited earlier.
Per-channel retainer benchmarks from WebFX’s 2026 guide break down as follows:
- SEO: $1,000–$30,000 per month
- PPC management: $1,500–$10,000 per month
- Content marketing: $4,000–$15,000 per month
Most digital marketing agencies package their services into retainers that sit somewhere within these ranges.
Directive Consulting vs SaaS Hero: Structural Differences
Directive Consulting is a performance marketing agency focused on B2B tech and SaaS, offering integrated paid media, SEO, and pipeline-tied reporting. Directive charges $5,000–$25,000+ per month plus ad spend.
Directive fits companies that have $25,000+ monthly ad budgets and need integrated paid and SEO execution. It also suits teams that operate in established B2B tech verticals with defined ICPs, can commit to longer initial contract terms, and have an internal RevOps function to receive and act on pipeline reporting.
Weakness: Directive’s fee structure includes a percentage-of-spend component on media management, which recreates the incentive misalignment described earlier for companies scaling spend aggressively. Contract flexibility is limited compared with month-to-month alternatives.
SaaS Hero operates on a flat monthly retainer with no percentage-of-spend component and month-to-month terms. Retainers start at $3,500 per month for a single channel managing up to $10,000 in ad spend and scale to $8,000 per month for three or more channels at $50,000+ in spend. Every plan includes a senior account strategist, dedicated campaign manager, competitor conquesting and ABM campaigns, a CRO program, and board-ready dashboards reporting Net New ARR, SQLs, CAC, LTV, and payback period connected to HubSpot or Salesforce. Case study outcomes include $504,758 in Net New ARR for TripMaster and an 80-day CAC payback period for TestGorilla.
SaaS Hero serves as a direct structural alternative to Directive for Series B companies spending $10,000–$50,000 per month that require flat fees, month-to-month flexibility, and closed-won revenue reporting.

B2B SaaS Google Ads Agency Alternatives to Directive
Powered by Search is a Canadian B2B SaaS-focused agency specializing in paid search, paid social, and demand generation for mid-market SaaS companies. It fits companies that need a specialist with deep B2B SaaS vertical knowledge rather than a generalist agency, are running Google Ads and LinkedIn Ads concurrently and need unified reporting, and prioritize MQL-to-SQL funnel reporting over top-of-funnel volume metrics.
Weakness: Powered by Search typically requires multi-month initial commitments and does not publish flat-retainer pricing publicly, which makes cost comparison difficult before a sales conversation.
TripleDart is a performance marketing agency focused on B2B SaaS paid media and demand generation, with published case studies across HR Tech, FinTech, and MarTech verticals. It fits companies that are Series A or early Series B and need cost-efficient paid search and LinkedIn management, want channel-level reporting tied to MQLs and pipeline rather than raw lead volume, and operate with ad budgets below $25,000 per month with a lean retainer structure.
Weakness: TripleDart’s reporting framework emphasizes MQL and pipeline metrics but does not consistently surface closed-won Net New ARR as the primary reporting layer, which limits its utility for boards that require revenue-first accountability.
Comparison Table: Billing, Terms, Channels, and ARR Reporting
The table below compares each agency on billing model, contract length, primary channel focus, and how closely reporting ties to ARR. These dimensions determine how well an agency supports CAC efficiency and board-level visibility.
| Agency | Billing Model | Contract Length | Primary Channel | ARR Outcome Reporting |
|---|---|---|---|---|
| SaaS Hero | Flat retainer, $3,500–$8,000/mo | Month-to-month | Google Ads, LinkedIn Ads, ABM | Net New ARR, CAC, LTV, payback period connected to CRM |
| Directive Consulting | Retainer + ad spend, $5,000–$25,000+/mo | Multi-month initial term | Paid search, SEO, paid social | Pipeline-tied reporting, closed-won ARR varies by engagement |
| Refine Labs | Retainer, $20,000–$31,000/mo | 6–12 month minimum typical | Demand generation strategy | Pipeline influenced, revenue attribution varies |
| Kalungi | Retainer, $6,500/mo fractional CMO coaching and $45,000/mo full-service | Multi-month initial term | Full outsourced marketing + fractional CMO | Revenue and ARR reporting included in fractional CMO scope |
| Ironpaper | Retainer, $10,000–$25,000/mo | 6–12 month minimum typical | ABM, content, lead gen | Pipeline and opportunity reporting, ARR attribution varies |
Early-Stage vs Scale-Up Alternatives by Profile
Profile 4 — New Breed ($7,500–$12,000+/month, HubSpot-centric): New Breed charges $7,500–$12,000+ per month for HubSpot-centric RevOps and demand generation retainers. It fits early Series A companies whose primary bottleneck is CRM hygiene and lead-to-opportunity conversion rather than paid media volume. The weakness is limited paid media execution depth, so companies needing aggressive competitor conquesting on Google Ads outgrow the model quickly.
Profile 5 — Refine Labs ($20,000–$31,000/month, demand generation strategy): Refine Labs charges $20,000–$31,000 per month for demand generation strategy and execution targeting mid-market and enterprise SaaS. It fits companies with $15M+ ARR whose bottleneck is category-level demand creation rather than paid search efficiency. The weakness is price, since the retainer floor exceeds the total marketing budget of most Series A companies, and most credible B2B agencies at this tier require six- to twelve-month minimums on retainers.
Profile 6 — Kalungi (fractional CMO and full-service marketing): Kalungi charges $6,500 per month for fractional CMO coaching and $45,000 per month for full-service engagements for venture-backed B2B SaaS companies. It fits companies that have no internal marketing function and need strategy, execution, and leadership in a single engagement. The weakness is cost relative to outcome specificity, since companies that already have a VP of Marketing and need only paid media execution pay for overhead they do not need.
Profile 7 — Ironpaper (ABM and content-led demand generation): Ironpaper focuses on ABM, content, and lead generation for B2B companies. It fits teams that want a content-heavy approach with ABM programs layered on top of existing channels and can commit to a six- to twelve-month retainer in the $10,000–$25,000 per month range. The weakness is variable ARR attribution depth, since reporting often centers on pipeline and opportunities rather than consistently tying every program back to Net New ARR.
Buyer-Stage Recommendation Framework for Agency Selection
The agency selection decision maps most cleanly to three variables: monthly ad spend, contract flexibility requirements, and reporting depth needed at the board level.
- $0–$10,000/month ad spend, pipeline bottleneck: New Breed or TripleDart. Focus on CRM setup and MQL-to-SQL conversion before scaling paid media.
- $10,000–$50,000/month ad spend, CAC and payback bottleneck, month-to-month required: SaaS Hero. As detailed in the comparison above, this option combines flat retainers, month-to-month terms, and Net New ARR reporting connected directly to HubSpot or Salesforce.
- $50,000+/month ad spend, category demand creation bottleneck: Refine Labs or Directive Consulting. Budget and contract commitment justify the higher retainer floor and longer initial term.
- No internal marketing team, Series A–B: Kalungi for a full outsourced function, or SaaS Hero for paid media execution alongside an existing internal team.
For Series B VPs of Marketing at $5M–$20M ARR spending $10,000–$50,000 per month on paid media, SaaS Hero stands out as the only option in this list that combines flat-retainer billing, month-to-month contract terms, competitor conquesting execution, and closed-won Net New ARR as the primary reporting metric within a single retainer that does not scale with ad spend.

30-Day Agency Evaluation Checklist for B2B SaaS
Use the following criteria as a connected framework when evaluating any agency on this list or any alternative not covered here.
- Billing model: Start by confirming whether the fee is a flat retainer or a percentage of spend. For companies between $5M and $50M in revenue focused on efficiency or with volatile budgets, flat retainers better match the actual work required than percentage-of-spend models.
- Contract length: Once the billing model aligns with your goals, evaluate contract length. Request month-to-month terms or a maximum 3-month initial commitment. Flat-fee contracts typically feature month-to-month or 3–6 month initial terms, while percentage-of-spend contracts typically require 12–24 months.
- Ad account ownership: With pricing and terms clarified, verify ad account ownership in writing. Confirm that your company owns the Google Ads and LinkedIn Ads accounts. Google’s policy specifies that advertisers own their Google Ads accounts, and contracts that fail to assign account ownership to the client create risk of losing years of conversion history upon termination.
- Competitor conquesting capability: After ownership is secure, assess strategic depth. Ask for examples of dedicated comparison and alternative landing pages built for prior clients. Agencies without this capability cannot intercept high-intent competitor-evaluation traffic.
- Revenue reporting depth: Next, evaluate reporting. Require a sample dashboard showing Net New ARR, CAC, CAC payback period, and pipeline value sourced from marketing. Proof points should include pipeline influenced, opportunity creation, lead-to-opportunity conversion rate, and cost per opportunity, not impressions or CTR.
- CRM integration: With reporting expectations set, confirm technical integration. Ensure the agency connects ad click data (GCLID) through to your CRM (HubSpot or Salesforce) to attribute closed-won revenue to specific campaigns. Revenue attribution connects marketing interactions directly to closed-won contract value, ARR, MRR, pipeline value, ROAS, and LTV:CAC ratios rather than volume-based metrics like MQLs or cost-per-lead.
- Client-to-manager ratio: Then examine resourcing. Ask how many active clients each account manager carries. Ratios above 10–12 clients per manager correlate with reactive rather than proactive account management.
- Reporting cadence: Finally, lock in communication expectations. Require weekly performance updates and bi-weekly strategy calls as a contractual minimum, not a premium add-on.
Conclusion: Choosing a SaaS-Focused Agency That Shares Your Incentives
Percentage-of-spend billing, 12-month lock-ins, and vanity-metric reporting function as structural features of a model that benefits the agency at the client’s expense. With median CAC payback periods for B2B SaaS increasing in recent years, a Series B VP of Marketing cannot afford an agency partner whose incentives run counter to CAC efficiency.
The seven agencies profiled above represent realistic alternatives to Directive Consulting for B2B SaaS companies in 2026. For companies spending $10,000–$50,000 per month that require flat fees, month-to-month flexibility, competitor conquesting execution, and Net New ARR as the primary reporting metric, SaaS Hero offers a focused option that delivers all four in a single engagement.
Frequently Asked Questions
What is the difference between flat-retainer and percentage-of-spend billing for B2B SaaS agencies?
A flat retainer is a fixed monthly fee that does not change based on how much the client spends on advertising. A percentage-of-spend model charges a variable fee, typically 15–30% of monthly ad spend, that grows automatically as the client increases their media budget. The structural problem with percentage-of-spend billing is that the agency earns more revenue when the client spends more, regardless of whether that additional spend generates proportional pipeline or revenue. This dynamic creates a financial incentive to recommend budget increases rather than efficiency improvements. Flat retainers decouple agency revenue from media volume, so recommendations to cut a wasteful campaign or reallocate budget to a higher-performing channel carry no financial penalty for the agency.
Why do month-to-month agency contracts matter for Series B SaaS companies?
Series B SaaS companies operate in a capital environment where budget flexibility functions as a strategic asset. A 12-month agency contract transfers all performance risk to the client, since the agency receives guaranteed revenue for a year while the client bears the consequences of underperformance with no practical exit. Month-to-month contracts invert this dynamic. The agency must re-earn the engagement every 30 days, which creates a continuous performance incentive rather than a post-signature complacency risk. For a VP of Marketing accountable to a board for CAC efficiency and pipeline generation, month-to-month terms also provide the flexibility to scale, pause, or redirect spend as the business’s go-to-market strategy evolves across funding stages.
What does Net New ARR reporting require from a marketing agency?
Net New ARR reporting requires the agency to connect ad click data, specifically Google Click IDs (GCLIDs) and LinkedIn click identifiers, through the client’s landing pages and into the CRM (HubSpot or Salesforce). This connection allows the agency to trace which campaigns, ad groups, and keywords generated leads that ultimately became closed-won customers and to sum the annual recurring revenue value of those customers. Net New ARR reporting differs from reporting on MQLs, form fills, or demo requests, which measure intent signals rather than revenue outcomes. Achieving this standard requires the agency to have direct access to CRM data, not just ad platform dashboards, and to build attribution models that account for multi-touch B2B sales cycles where a prospect may interact with multiple campaigns before signing a contract.
How does competitor conquesting work as a paid media strategy for B2B SaaS?
Competitor conquesting is a paid search strategy that targets users actively searching for a competitor’s product using keywords that signal evaluation intent, such as “[Competitor] pricing,” “[Competitor] alternatives,” or “[Competitor] vs [Your Product].” These users are already in the market for a solution in the category and often experience friction with the competitor’s product or pricing. The strategy requires building dedicated landing pages that match the search intent precisely. A pricing-intent keyword sends traffic to a direct cost comparison page, while an alternatives-intent keyword sends traffic to a page that addresses known competitor weaknesses and presents switching resources. Effective competitor conquesting also requires negative keyword hygiene to exclude navigational searches, such as users looking for the competitor’s login page, that generate clicks but no conversion intent.
How should a VP of Marketing evaluate whether SaaS Hero is the right fit versus a larger agency like Refine Labs or Kalungi?
The decision maps to three variables: budget, internal team structure, and reporting requirements. SaaS Hero is purpose-built for companies spending $10,000–$50,000 per month on paid media that already have a VP of Marketing or internal marketing function and need a senior-led paid media execution partner operating on flat fees and month-to-month terms. Refine Labs suits companies with $15M+ ARR whose primary bottleneck is category-level demand creation and who can commit to a $20,000–$31,000 per month retainer with a multi-month initial term. Kalungi suits companies with no internal marketing leadership that need a fractional CMO alongside full execution. If the core requirement centers on flat billing, month-to-month flexibility, competitor conquesting, and Net New ARR reporting connected to the CRM, without paying for fractional CMO overhead or committing to a long-term contract, SaaS Hero represents the most direct structural fit in the market.
