If you run a paid-ads agency, you've felt this: the tools your clients want — Triple Whale, Hyros, Northbeam — are all built for single brands. Charging the agency tier turns into "talk to sales," and "talk to sales" turns into $1,500–$2,500/mo before you serve client #5.
Margins disappear. Clients still want the dashboards. So you either eat the cost or pass it through, and either way it's a tax on running an agency in 2026.
Here's the stack we'd assemble today if we were starting an agency from scratch.
Layer 1: Attribution + dashboards (the source of truth)
This is the layer that has to do multi-workspace and white-label well, or nothing else matters.
What to look for:
- Per-client workspaces with their own pixels, integrations, and dashboards. One login, all clients.
- White-label — your logo on every screen the client sees. Custom domain (status.youragency.com). Email templates carry your name, not the vendor's.
- Flat pricing, not per-client license fees. The math has to work whether you serve 5 clients or 50.
- First-party pixel — agencies live in the gap left by ad-platform attribution. A first-party signal that survives ad blockers and tracking-prevention is the differentiator.
This is where Persequor fits. $599/mo flat covers up to 50 workspaces, white-label is included (not an upcharge), and the pixel + Shopify + Calendly + Meta/Google/TikTok integrations are all native. More on the agency angle here.
Layer 2: Ad accounts + creative management
Meta Business Manager + Google Ads MCC. Free, both. Both let you manage many ad accounts under one parent account with proper team roles.
If your team is 3+: Madgicx ($55–$144/mo) or AdEspresso for creative testing automation, but be aware these add another vendor in your stack with their own attribution layer that'll disagree with your source-of-truth dashboard. We'd skip them and run creative testing manually until $50k+/mo ad spend.
Layer 3: Reporting + client communication
You need to send weekly numbers to clients in a way that doesn't require them to log in. Two paths:
- Loom + Google Slides — record yourself walking through the dashboard once a week. Personal, builds the relationship, doesn't require any tooling.
- Slack/email digest from your attribution tool — automated, scales better, less personal. Most clients prefer Loom for the first 90 days, then prefer the digest after that.
If you're going the digest route: most attribution tools can do this natively. If yours can't, Zapier is your friend — pull the weekly numbers from your dashboard's API and pipe them to a templated email or Slack channel.
Layer 4: Client onboarding
The hardest part of agency life is onboarding new clients. The unsexy answer is templates:
- Notion playbook templated per client type (DTC vs lead-gen vs SaaS).
- Calendly for kickoff scheduling — your attribution tool should track Calendly bookings as conversions so when you A/B test landing pages for client acquisition, the data flows back.
- DocuSign or HelloSign for contracts. Don't waste time on a fancier tool than this needs.
Layer 5: Internal ops
Linear for internal tickets. Slack with shared channels per client (Slack Connect). Notion for client-facing docs and your internal SOPs.
Avoid: ClickUp (too much), Trello (too little), Asana (in between, but somehow worse than both).
The one tool we'd actually pay for first
If you're starting an agency tomorrow with $0 in the budget, prioritize the attribution layer. Your clients will judge you on the dashboard. They won't notice your project management tool. They will notice if your ROAS numbers don't match their Shopify totals.
The agency that ships the cleanest reporting wins the renewal. The agency that ships the cleanest actually-correct reporting wins the referrals.
If multi-workspace + white-label are the bottleneck, we built Persequor's Agency plan exactly for this. If they're not, the rest of the stack is mostly free.
