SaaS Stack for Marketing Agencies: PM, Reporting, Social, Email, and CRM
Marketing agencies need project management across multiple clients, social scheduling, email marketing, client reporting, and a CRM. Here's the exact stack from $0 to full-service agency setup — with verified pricing and per-client cost modeling.
Recommended Stack (10-person agency)
| Need | Tool | Plan | Price |
|---|---|---|---|
| Project Management | ClickUp | Unlimited | $10/member/mo ($100/mo for 10) |
| Client CRM | Pipedrive | Growth | $39/seat/mo ($78/mo for 2 sales seats) |
| Social Media | Buffer | Essentials | $6/channel/mo ($60/mo for 10 channels) |
| Email Marketing | ActiveCampaign | Starter | $15/mo (1,000 contacts) |
| Automation | Make | Core | $10.59/mo (10,000 ops) |
| SEO | Mangools | Entry | $29.90/mo |
| Total | ~$294/mo | ||
Per-Client Cost Modeling
At $294/mo total stack cost with 10 clients: $29.40/client/month in software overhead.
At 20 clients (add Buffer channels and ActiveCampaign contacts): ~$360/mo = $18/client/month.
At 50 clients: ~$500/mo = $10/client/month.
Software cost per client drops as you scale. The largest variable cost is social channels (Buffer Essentials at $6/channel).
Why These Tools
ClickUp Unlimited ($10/member/mo) for Project Management
Agencies need to manage multiple client workspaces, track deliverables, and manage deadlines. ClickUp Unlimited gives unlimited storage, dashboards, and Gantt charts at $10/member. Use Spaces for each client and Lists for campaign types. Alternative: Asana Starter at $13.49/seat/mo for teams preferring a cleaner interface. Monday Standard at $14/seat/mo for visual boards.
Buffer Essentials ($6/channel/mo) for Social Media
Buffer's per-channel pricing scales well for agencies managing 5–20 social accounts. Essentials gives unlimited posts, engagement tools, and 30-day analytics. For larger agencies, Buffer Team at $12/channel/mo adds approval workflows. Alternative: Hootsuite Standard at $149/mo for a single user managing up to 10 accounts — but that's $149 for 1 user vs Buffer at $60 for 10 channels.
Mangools Entry ($29.90/mo) for SEO
For agencies managing SEO for multiple small-to-mid clients, Mangools provides keyword research, rank tracking, and backlink analysis at a fraction of Semrush Pro's $139.95/mo. The Entry plan includes 100 keyword lookups/day and 25 SERP lookups. For agencies needing more, Mangools Basic at $49.90/mo offers unlimited lookups.
Budget Tiers
| Tier | Key Changes | Monthly Cost |
|---|---|---|
| $0 Starter | ClickUp Free + HubSpot CRM Free + Buffer Free (3 channels) + Make Free (1,000 ops) | $0/mo |
| Freelance Agency | ClickUp Unlimited ($10) + Pipedrive Lite ($14) + Buffer Essentials (3 channels = $18) + Make Core ($10.59) | ~$53/mo |
| Full-Service (10 people) | Full recommended stack above | ~$294/mo |
Frequently Asked Questions
Should we use Semrush instead of Mangools?
If your agency offers PPC management alongside SEO, yes. Semrush Pro at $139.95/mo covers both SEO and PPC keyword research. If you only do SEO, Mangools at $29.90/mo saves $110/mo with sufficient keyword research and rank tracking for most small-to-mid clients.
Why Pipedrive instead of HubSpot for agency CRM?
Pipedrive Growth at $39/seat/mo gives you email sync, automations, and a visual pipeline optimized for deal-closing. HubSpot Free works for tracking contacts, but HubSpot Professional (for real marketing automation) jumps to $890/mo flat. Pipedrive keeps agency sales management affordable.
What about client reporting?
ClickUp dashboards can serve as basic client reports. For dedicated reporting, Google Looker Studio (free) pulls data from Google Analytics, Search Console, and social platforms. Most agencies find that Looker Studio plus manual exports from Buffer and Mangools covers their reporting needs.
