Key Takeaways
- B2B SaaS companies struggle with traditional agency pricing models like percentage-of-spend that reward higher ad spend instead of efficient CAC.
- Hourly and project-based pricing gives cost control but creates inflexibility and uncertainty for ongoing SaaS campaign improvements.
- Long-term retainers provide predictable costs but often reduce accountability because 6-12 month lock-ins limit agile growth pivots.
- Tiered packages improve clarity yet often hide scope limits and upsell pressure that do not match SaaS-specific requirements.
- Flat monthly retainers with spend bands and month-to-month terms work best, keeping agencies accountable to performance; schedule a discovery call with SaaSHero to apply this model to your growth plan.

1. Percentage-of-Spend Pricing Creates Misaligned Incentives
The percentage-of-spend model remains the most common pricing structure in digital marketing, with agencies charging 10-20% of the total ad budget. For a SaaS company spending $25,000 each month on Google Ads and LinkedIn, this equals $2,500-$5,000 in agency fees, before setup costs or add-ons.
This model misaligns agency incentives with client outcomes. Agencies earn more when clients spend more, regardless of efficiency. A campaign generating $50 CPAs might be scaled aggressively because higher spend increases fees, even when your target CPA should be $100-200 based on current B2B SaaS benchmarks.
Typical Structure:
- 10-15% for budgets under $10,000
- 15-20% for budgets $10,000-$50,000
- Platform management across Google Ads, LinkedIn, and Meta
- Monthly reporting focused on impressions, clicks, and CTR
Pros: Scales with budget growth, agencies often assign more resources to larger accounts
Cons: Encourages wasteful spending, creates unpredictable costs, conflicts with SaaS unit economics
For a Series A SaaS company targeting 80-day payback periods, percentage-based fees can consume 20-30% of your marketing budget in agency costs alone. That cost level makes efficient CAC nearly impossible.
2. Hourly and Project-Based Pricing Limits Continuous SaaS Growth
Hourly and project-based pricing attracts cost-conscious founders who want granular control over agency spend. Full-service B2B marketing agencies charge $165-$225 per hour on average, and specialized PPC management often commands even higher rates in competitive markets.
This model does not support the continuous improvement required in B2B SaaS marketing. Website redesigns can function as one-time projects. Paid media for SaaS needs daily bid adjustments, weekly keyword expansion, and monthly landing page testing to keep performance strong as markets shift.
Typical Structure:
- $150-$300 per hour for strategy and execution
- $10,000-$50,000 project fees for campaign setup
- Separate billing for creative assets and landing pages
- Limited ongoing optimization included
Pros: Clear time tracking, pay only for documented work
Cons: Scope creep risk, volatile monthly costs, weak fit for long-term growth programs
SaaS companies that aim for steady month-over-month growth often find that hourly billing creates budget swings that clash with predictable revenue planning and investor reporting.
3. Long-Term Retainers Shift Performance Risk to the Client
Traditional retainers offer predictable monthly costs but usually require 6-12 month commitments that shift performance risk to the client. B2B content marketing agencies start at $10,000 monthly, with full-service SEO reaching $22,900 per month under these extended contracts.
Long-term contracts often create moral hazard. Agencies push hard during the first 90 days, then coast on guaranteed revenue. SaaS companies need agile responses to market changes, competitor moves, and funding milestones. Contractual lock-ins slow or block these pivots.
Typical Structure:
- $5,000-$15,000 monthly retainer
- 6-12 month minimum commitment
- Defined deliverables and reporting schedule
- Limited flexibility for budget reallocation

Series B companies targeting 120%+ Net Revenue Retention need partners who stay accountable to results, not just contracts. Book a discovery call to explore month-to-month options that match your growth trajectory.
4. Tiered Packages Improve Clarity but Often Hide Gaps
Tiered package pricing aims to balance predictability with scalability by offering several service levels at fixed monthly rates. This structure usually feels clearer than percentage-based fees and can match different company stages and budgets.
Many agencies still write vague package descriptions that hide scope limits and upsell paths. A label like “comprehensive PPC management” might exclude competitor campaigns, landing page testing, or advanced attribution tracking. These elements matter for B2B SaaS performance.
Typical Structure:
- Starter: $3,000-$5,000 (single channel, basic reporting)
- Growth: $7,500-$12,000 (multi-channel, conversion tracking)
- Enterprise: $15,000+ (full-service, dedicated team)
- Setup fees: $2,000-$5,000
Pros: Clear pricing tiers, scalable with growth, defined service levels
Cons: Hidden exclusions, upsell pressure, generic packages that ignore SaaS-specific needs
Scale-up SaaS companies often learn that a “Growth” package excludes essentials like competitor conquesting or CRM integration. These gaps force expensive upgrades that were not obvious during procurement.
5. Flat Monthly Retainers with Spend Bands Keep Agencies Accountable
Flat monthly retainers with spend bands give B2B SaaS companies a transparent, performance-aligned pricing model. This structure removes percentage-based conflicts and creates predictable costs that scale logically with ad spend tiers.
Leading agencies use retainers based on ad spend bands and channel count. One example is $1,250 monthly for managing up to $10,000 in spend on a single channel on a month-to-month basis, with higher tiers for more channels and larger budgets. This approach rewards efficiency instead of volume and connects agency success to CAC targets and payback periods.

Case studies support this model. TripMaster generated $504,758 in Net New ARR with 650% ROI. TestGorilla reached 80-day payback periods that supported their $70M Series A. Month-to-month terms require agencies to re-earn your business every 30 days, which keeps performance urgency high.

Frequently Asked Questions: Transparent Pricing for B2B SaaS Agencies
How much does a B2B marketing agency cost?
B2B marketing agencies usually charge $4,500-$10,000 or more per month for comprehensive services. Specialized SaaS agencies often range from $1,250-$5,000 monthly, depending on ad spend volume and channel count. Setup fees typically add $1,000-$2,000 for campaign architecture and tracking.
What is a good CPA for B2B SaaS?
Target CPAs for B2B SaaS often fall between $50 and $200, depending on average contract value and sales cycle length. Enterprise SaaS with $50,000+ ACVs can support $500+ CPAs, while SMB-focused products usually need sub-$100 acquisition costs to protect unit economics.
How much should I charge for B2B SaaS marketing services?
Flat retainer pricing usually works best for SaaS marketing services. Charge $1,000-$3,000 monthly for single-channel management up to $25,000 in ad spend, then scale to $4,000-$7,000 for multi-channel programs. Avoid percentage-based fees that reward higher spend instead of better performance.
What pricing differences exist between startups and scale-ups?
Pre-Series A startups typically budget $1,250-$2,500 monthly for focused channel testing. Series A and later companies often invest $3,000-$10,000 or more each month for multi-channel growth programs. Scale-ups need deeper attribution and CRM integration, which supports higher service tiers.
Why choose month-to-month over annual contracts?
Month-to-month agreements align agency accountability with client results. Agencies must prove value continuously instead of relying on long-term guarantees. This flexibility supports rapid strategy shifts during funding rounds, competitive threats, or market changes that frequently affect SaaS companies.
Conclusion: Choose Pricing That Supports Efficient SaaS Growth
