FAQ

SaaS attribution questions

Does this work with PLG funnels (free signup → trial → paid)?

Yes. Attribution follows the customer through every state change: anonymous visit, free signup, trial start, trial conversion, paid, expansion, churn. Every state change writes back to your CRM and warehouse with the source and journey attached.

Can I attribute MRR and LTV, not just signups?

Yes. Connect Stripe, Paddle, Polar.sh, or your billing tool via OAuth. Subscription events (initial paid, renewal, expansion, downgrade, churn) flow into SourceLoop with the original acquisition source attached. Reports roll up MRR, ARR, and LTV by channel.

How does account-level attribution work for ABM?

Multi-touch attribution rolls up to the company, not just the contact. Anonymous visits get matched to known accounts via IP enrichment, reverse DNS, and known visitor identity. Buying-committee-level reports show which channels reached the right accounts, not just leads.

We're early-stage and don't have a CRM. Will this still work?

Yes. SourceLoop's built-in Contacts Hub is a lightweight CRM that captures every signup and trial automatically. When you graduate to HubSpot or Salesforce later, attribution syncs over without losing history.

Can I sync paid customers as a customer audience to Google or Meta?

Yes. Build segments by paid plan, MRR threshold, or LTV bracket and sync to Google Ads, Meta, or LinkedIn as customer audiences. Use them for retargeting, exclusion lists, or value-based bidding signals.

Track every conversion to its true source

Capture and send full attribution data from every signup, lead, booking, and sale to your CRM and ad platforms, so you know exactly what's driving revenue.
