Lemon SqueezyAny SaaS motion
Self-serve or sales-assisted, attributed the same way
Most SaaS runs both motions at once. Marketing attribution is available at every level of granularity, from the first visit through signup, trial, lifecycle stage, opportunity, deal, and the recurring revenue that follows. Whichever path a customer takes, every stage traces back to the campaign that started it.

Trials and subscriptions
See which marketing campaigns bring trials that convert
Trial starts, conversions, and active subscriptions broken down by the campaign that produced them, so the campaign filling your trial list and the one filling your revenue are never confused for each other.
Recurring revenue
Every subscription tied to the campaign that won it
Month two onwards is where subscription revenue actually lives. Renewals, upgrades, and MRR stay credited to the original campaign, so recurring revenue is measured against what it cost to acquire.
Lifetime value
Rank channels on LTV, not first payment
Renewals and expansions stay credited to the campaign that won the customer, so a channel producing cheap signups who churn at month two stops outranking the one producing customers who stay for years.

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.
We are sales-led, not product-led. Does this still work?
Yes. The stages differ but the model does not. Instead of signup, trial, and paid, you attribute demo booked, meeting held, opportunity created, and closed won, using the lifecycle stages already in HubSpot, Salesforce, or Pipedrive. Deal value flows back to the campaign the same way subscription revenue does.
We run self-serve and sales-assisted side by side. Can we compare them?
Yes, and this is where most SaaS reporting falls apart, because the two motions usually live in separate tools. SourceLoop keeps both on one dataset, so you can see cost per customer and lifetime value for the self-serve plan and the sales-assisted plan next to each other, by campaign.
