Cello vs PartnerStack (2026): which should you pick?

Pick Cello if

• Fits if you run B2B SaaS and want referrals from both users and partners
• Works for small partner programs that stay under 5 transacting partners

Look elsewhere if

• Skip it if your referral ARR is above $10K, where the next user plan is $200 a month
• Tight if you grow past 5 partners, as the next partner plan is $80 a month
• Watch out: partner plans take a transaction cost of 5% on Free and 3.5% on Plus and Pro
• Watch out: the page shows dollars but its pricing data lists euros, so check the currency at sign-up

Pick PartnerStack if

• Fits if you're a B2B software company running affiliates and resellers together
• Works for teams whose partners register deals that need to land in Salesforce or HubSpot

Look elsewhere if

• Skip it if you want to see a price before booking a demo
• Not for you if you're a small business wanting to start this week, as setup takes weeks
• Tight if you want links and deal registration together, as Launch has one or the other
• Watch out: you pay commissions in US dollars or euros only, though partners can withdraw in their own currency
• Skip it if you want a trial or free plan, as there's neither, and it's web only

Cello

• User-referral plans are capped by referral ARR: $10K, $50K and $100K, with Enterprise for more.
• The page text shows dollars, but its structured pricing data lists euro amounts, so confirm the currency at sign-up.
• Partner referrals charge a transaction cost of 5% on Free, 3.5% on Plus and Pro, and 2% on Enterprise.
• Dedicated success manager is not on the Start plan.

PartnerStack

• No prices are published: Launch, Growth and Enterprise are quoted after a demo, based on program size, features and support.
• Launch includes either affiliate link tracking or lead and deal registration, not both; Enterprise unlocks every partner motion.
• Vendors pay commissions in US dollars or euros only, though partners can withdraw in their local currency.
• Every plan starts with a demo and guided onboarding, and PartnerStack says most teams are running within weeks.
