Attribution App vs LeadSources (2026): which should you pick?

Pick Attribution App if

• Fits if you run a Shopify store with real ad spend and want attribution plus incrementality
• Works for HubSpot teams that want one attribution view

Look elsewhere if

• Pricey if you are a small store, as the lowest plan is $199 a month
• Tight if your traffic grows: overage is $10 per 1,000 tracked users above 10,000
• Skip it if you need data export or API access in the base price, as it is an add-on
• Watch out: onboarding is listed at $2,500 to $5,000

Pick LeadSources if

• Fits if most of your leads arrive through website forms
• Works for agencies that connect several client sites

Look elsewhere if

• Skip it if you track calls, chats or store sales, as it centres on form leads
• Tight if you get many leads: 250, 1,000 or 2,500 a month by plan
• Pricey if you have several sites, as 3 websites cost $148 a month
• Watch out: the page shows monthly prices by default, and yearly billing is only advertised as 20% cheaper
