De Tech Stack van een $10M ARR B2B-bedrijf
When a B2B SaaS company crosses the $10M ARR mark, the tool stack that got them there starts buckling. The spreadsheet-based billing process that worked at $500K breaks with 2,000 customers. The startup CRM that handled 5 reps can't support 30. The analytics dashboard that one person maintained now needs three people and a data warehouse.
This is the stack architecture of a $10M ARR B2B company — what each layer does, what it costs, and where the integration points create the most friction. It's based on composites from operators we've worked with, not a theoretical ideal.
The Stack Architecture
A $10M ARR B2B company runs approximately 25-40 SaaS tools across seven functional layers. Here's how they connect:
┌─────────────┐ ┌─────────────┐ ┌─────────────┐
│ Marketing │ │ Sales │ │ Support │
│ HubSpot │←→│ Salesforce │←→│ Zendesk │
│ + Webflow │ │ + Gong │ │ + Intercom │
└──────┬───────┘ └──────┬───────┘ └──────┬───────┘
│ │ │
└────────┬────────┴────────┬────────┘
│ Data Layer │
┌───────┴────────┐ ┌─────┴──────┐
│ Snowflake/BQ │ │ Segment │
│ (Warehouse) │ │ (CDP) │
└───────┬────────┘ └─────┬──────┘
│ │
┌───────┴────────────────┴──────┐
│ Revenue Ops │
│ Stripe + ChartMogul + Deel │
└───────────────────────────────┘
The connections between these layers are where complexity lives. A contact in HubSpot needs to sync with Salesforce, which needs to reflect billing status from Stripe, which needs to reconcile with revenue data in Snowflake. Each connection is a potential point of failure.
The Core Layer: CRM and Data
The CRM is the system of record for customer relationships. At $10M ARR, this is almost always Salesforce or HubSpot — the decision between them depends on whether you prioritize marketing-sales unification (HubSpot) or process customization (Salesforce).
The Reference CRM Stack
| Tool | Function | Annual Cost (est.) |
|---|---|---|
| Salesforce Sales Cloud (Enterprise) | CRM, pipeline, forecasting | $38,400 (40 seats × $80/mo) |
| Gong | Conversation intelligence, deal analytics | $36,000 |
| Clari | Revenue forecasting, pipeline inspection | $24,000 |
| LinkedIn Sales Navigator | Prospecting, social selling | $14,400 (15 seats × $80/mo) |
| Apollo or ZoomInfo | Data enrichment, outreach | $18,000-$36,000 |
| Subtotal | $130,800-$148,800 |
The CRM layer alone runs $130K-$150K/year. That's 1.3-1.5% of revenue — within the typical range. Companies that try to economize here end up paying more in lost productivity and bad data.
Data Infrastructure
At $10M ARR, you need a data warehouse. Dashboards connected directly to production databases don't scale, and marketing teams can't run SQL queries against Salesforce.
| Tool | Function | Annual Cost |
|---|---|---|
| Snowflake or BigQuery | Data warehouse | $12,000-$36,000 |
| Fivetran or Airbyte | Data ingestion (ETL) | $12,000-$24,000 |
| dbt | Data transformation | $0 (open source) - $6,000 |
| Looker or Metabase | Business intelligence | $12,000-$60,000 |
| Segment or RudderStack | Customer data platform | $12,000-$36,000 |
| Subtotal | $48,000-$162,000 |
The range is wide because data warehouse costs depend heavily on query volume and data retention. A well-optimized Snowflake deployment for a $10M company costs $12K/year. A poorly optimized one costs $100K+.
Revenue Operations Tools
Revenue ops is the financial infrastructure — billing, subscription management, revenue recognition, and the systems that turn usage into invoices.
| Tool | Function | Annual Cost |
|---|---|---|
| Stripe Billing | Payment processing, subscriptions | 2.9% + $0.30/transaction |
| ChartMogul or Baremetrics | SaaS metrics (MRR, churn, LTV) | $6,000-$12,000 |
| Chargebee or Zuora | Subscription management (complex billing) | $12,000-$60,000 |
| Deel or Rippling | Payroll, HR, contractor payments | $12,000-$36,000 |
| Brex or Ramp | Corporate cards, expense management | $0-$6,000 |
| Subtotal | $30,000-$114,000 (+ Stripe fees) |
The critical decision here: Stripe alone vs Stripe + subscription management platform. If your billing is straightforward (monthly/annual subscriptions, no usage-based pricing, no complex discounting), Stripe Billing handles everything. Once you add usage-based pricing, enterprise contracts with custom terms, or multi-currency billing, you need Chargebee or Zuora.
At $10M ARR, Stripe processing fees alone run $250K-$300K/year (assuming 2.9% on $10M). That's your single largest vendor expense. Negotiate — Stripe offers volume discounts starting at $1M in annual processing.
The Integration Glue
This is where most companies bleed money. The tools work fine individually. Connecting them is the challenge.
Integration Architecture Options
| Approach | Best For | Annual Cost | Reliability |
|---|---|---|---|
| Native connectors (built-in) | Simple, supported integrations | Included in tool licenses | High (when available) |
| Zapier/Make | Low-volume, non-critical workflows | $3,600-$12,000 | Medium |
| Tray.io or Workato | Complex, business-critical workflows | $24,000-$60,000 | High |
| Custom code (Node.js/Python) | Unique requirements, high-volume | $20,000-$50,000 (dev cost) | Variable (depends on maintenance) |
| Reverse ETL (Census, Hightouch) | Warehouse → operational tools | $12,000-$36,000 | High |
The emerging pattern: use the data warehouse as the integration hub. Rather than connecting every tool to every other tool, pipe everything into Snowflake/BigQuery, transform it there, then push it back to operational tools via reverse ETL. This reduces the number of integration points from O(n²) to O(n).
For CRM integration patterns specifically, the middleware approach (Tray.io or Workato) provides the best balance of reliability and flexibility for $10M ARR companies.
Marketing and Sales Tools
| Tool | Function | Annual Cost |
|---|---|---|
| HubSpot Marketing Hub (Professional) | Email, automation, landing pages | $9,600 |
| Webflow or Custom site | Website | $3,600-$30,000 |
| Google Ads + LinkedIn Ads | Paid acquisition | Variable ($50K-$500K/yr) |
| Outreach or Salesloft | Sales automation | $18,000-$30,000 |
| Drift or Intercom (Sales) | Chat, chatbot, meeting scheduling | $12,000-$24,000 |
| 6sense or Demandbase | Intent data, ABM | $36,000-$72,000 |
| Subtotal | $79,200-$165,600 (+ ad spend) |
The tool that most $10M companies add and later regret: ABM platforms. 6sense and Demandbase are powerful but require dedicated ops resources to configure, maintain, and action the intent signals. Without those resources, the platform generates data nobody acts on — at $36K-$72K/year.
Cost and Scaling
Total Stack Cost at $10M ARR
| Layer | Annual Cost Range |
|---|---|
| CRM and Sales | $130,800-$148,800 |
| Data Infrastructure | $48,000-$162,000 |
| Revenue Operations | $30,000-$114,000 |
| Marketing and Sales Tools | $79,200-$165,600 |
| Support (Zendesk/Intercom) | $24,000-$60,000 |
| Engineering/DevOps | $36,000-$120,000 |
| Collaboration (Slack, Notion, etc.) | $12,000-$24,000 |
| Total | $360,000-$794,400 |
That's 3.6% to 7.9% of revenue on SaaS tools. The industry benchmark for B2B SaaS is 5-8% of revenue on tool spend. Companies below 5% are usually under-investing in data and automation. Companies above 8% likely have redundant tools.
Where to Invest vs Where to Cut
Invest more: Data infrastructure (the compounding value of unified data is worth every dollar), CRM customization (a well-configured CRM saves 10+ hours per rep per week), and revenue ops (accurate billing and forecasting become critical above $5M ARR).
Cut: Overlapping tools (audit quarterly — most companies run 2-3 tools that do the same thing), enterprise features nobody uses (downgrade to the tier that matches your actual usage), and point solutions that could be replaced by features in existing platforms.
FAQ
How often should we audit our tool stack? Quarterly. Map every tool to its primary user, monthly cost, and utilization rate. Any tool with fewer than 5 active users or less than 30% feature utilization is a candidate for elimination or downgrade.
When do we need a dedicated ops person for the stack? At $3-5M ARR. Before that, a tech-savvy marketer or sales leader can manage the stack part-time. After $5M, the integration complexity, data quality maintenance, and vendor management require a dedicated head — typically a Revenue Operations Manager ($90K-$130K/year).
Should we consolidate tools onto fewer platforms? The consolidation instinct is usually right. Running HubSpot for marketing + Salesforce for sales + Zendesk for support means three systems, three data models, and dozens of integration points. HubSpot's all-in-one approach reduces integration complexity at the cost of feature depth. The right answer depends on whether your processes need Salesforce-level customization or whether HubSpot covers 90% of your needs.
How do we negotiate better vendor pricing? Annual contracts (20-30% discount over monthly). Multi-year commitments (additional 10-15%). End-of-quarter negotiation (vendor reps have quotas). Competitive bids (get quotes from 2-3 vendors before signing). Volume discounts (ask explicitly — they're rarely offered proactively).
Your tech stack is infrastructure, not a shopping list. Every tool should earn its place through measurable impact on revenue, productivity, or data quality.
