Cello

Cello is referral software for partner and user-referral programs, combining referral links and codes with fraud controls and reward payouts. It is best suited to teams that want partner capacity to scale through clearly defined monthly tiers. The free entry point works for a small pilot, while larger programs must budget for campaign, partner, or referral-ARR limits.

Overview

Cello brings the core mechanics of a referral program into one service: links and codes for attribution, controls intended to limit fraudulent activity, and payouts through PayPal or Venmo. Unlimited referrals are included in every listed plan, so the practical constraint is not the number of referrals themselves. Instead, businesses choose a tier according to the number of campaigns, transacting partners, or referral revenue they need to support.

That structure makes Cello a sensible starting point for a focused partner initiative, but less compelling when a business immediately needs many separate campaigns or a large partner base. The enterprise options remove those ceilings, although their pricing is custom.

Key features

Links, codes and rewards

Referral links and referral codes provide two attribution routes, useful when participants share trackable URLs in some contexts and codes in others. PayPal and Venmo payouts give programs established methods for sending rewards, rather than leaving payment handling outside the referral workflow.

Fraud controls and capacity

Fraud controls are important for programs where incentives can attract duplicate or abusive activity. Cello pairs those controls with unlimited referrals on every plan, but campaign and partner allowances vary sharply. Free supports one partner campaign and five transacting partners. Plus raises that to three campaigns and 25 partners, while Pro allows 10 campaigns and 100 partners. Grow and Scale include all integrations and all features, with referral-ARR ceilings of $50K and $100K. Partner Referrals Enterprise removes campaign and partner limits; User Referrals Enterprise removes the referral-ARR ceiling and adds custom SLAs.

Pricing

Cello uses monthly billing. Free costs $0.00 per free and includes unlimited referrals, one partner campaign, and five transacting partners. It is appropriate for validating one small partner program, but the five-partner ceiling will quickly restrict a broader launch.

Plus costs $80.00 per month and allows unlimited referrals, three partner campaigns, and 25 transacting partners. It suits a growing program that needs several campaigns without moving into high-volume tiers. Pro is $280.00 per month, with 10 campaigns and 100 transacting partners; it is the more realistic choice for a substantial partner operation.

Grow costs $200.00 per month and supports up to $50K in referral ARR, with unlimited referrals, all integrations, and all features. Scale costs $750.00 per month and raises the ceiling to $100K while retaining those inclusions. These plans are oriented toward referral revenue rather than campaign count, so they fit organizations measuring growth by ARR. Partner Referrals Enterprise and User Referrals Enterprise use custom pricing; the former offers unlimited partner campaigns and partners, while the latter offers unlimited referral ARR and custom SLAs.

Platforms

Cello is offered on Android, iOS, and the web, giving participants and administrators access across mobile and browser environments.

Who it's for

Choose Cello for a business launching a partner or user-referral program that needs links or codes, fraud controls, and PayPal or Venmo rewards in one product. Free is a reasonable fit for a single campaign with no more than five transacting partners. Plus and Pro suit organizations adding campaigns and partners in measured steps. Grow or Scale make more sense when referral ARR is the primary planning metric and all integrations and features are required.

Look elsewhere if your program needs uncapped capacity at a published price, or if even the Free plan's one-campaign and five-partner limits are too restrictive.

Pros and cons

Pros

• Links and codes: supports two common referral-attribution methods.
• Fraud controls: addresses incentive abuse as part of the referral setup.
• PayPal and Venmo payouts: provides familiar reward-payment channels.
• Unlimited referrals: referral volume itself is not capped on the listed plans.
• Clear upgrade path: campaign, partner, and ARR-based tiers accommodate different stages of growth.

Cons

• Strict free caps: one campaign and five transacting partners limit the no-cost plan to small pilots.
• Monthly cost rises quickly: Pro is $280.00 per month, while Scale is $750.00 per month.
• Enterprise pricing is custom: uncapped partner or user-referral deployments cannot be budgeted from a posted price.
• Different scaling measures: campaign-and-partner tiers and ARR tiers require teams to choose the pricing model that matches their program.

Verdict

Cello is a strong choice for teams that need referral links or codes, fraud controls, and PayPal or Venmo payouts with unlimited referral volume. Its Free, Plus, and Pro tiers provide a straightforward path for partner programs that can live within campaign and transacting-partner limits. Choose an enterprise tier when those limits or referral-ARR ceilings no longer fit; look elsewhere if custom pricing or the monthly cost of higher tiers makes planning difficult.
