Divide paid ad spend by the number of closed-won customers it produced. Use the same time window for both, and give deals long enough to close. If $20,000 of spend brings in 3 closed-won deals, paid CAC is $6,667. Leave out organic and referral deals. Add sales team costs only if you want a fully loaded CAC.
What is a good CAC payback period for B2B SaaS in 2026?
Many B2B SaaS teams aim to earn back paid CAC within 12 months of gross margin. To find yours, divide closed-won CAC by the monthly gross margin one customer brings in. A $6,667 CAC against $1,000 of monthly gross margin pays back in about seven months. Track it by campaign, because payback often differs a lot between channels.
Why does Google Ads report a lower CAC than my CRM?
Google Ads counts a conversion when someone fills a form or books a demo, while your CRM counts a customer when a deal closes. Most demo requests never sign, so platform CAC looks cheaper. Attribution windows widen the difference. If a deal closes outside the window, the platform never links that customer to the ad that found them.
Can I see cost per MQL, SQL and closed-won deal by campaign?
Yes. Connect your ad accounts and Pipedrive, and Flyweel lines up spend with each deal stage by campaign. Cost per MQL, cost per SQL and cost per closed-won deal sit side by side. The AI agent answers questions on the same data, such as which campaign has the lowest cost per SQL this quarter.
Does Flyweel work with HubSpot or Salesforce?
Not yet. Pipedrive is the live CRM connection today, and HubSpot and Salesforce are on the roadmap. Meta, Google Ads and TikTok connect on the ad side, and Xero or QuickBooks on the accounting side. Data without a direct connection, such as a CRM export, can come in by CSV upload.
