Tool Breakdown
FirstPromoter
It's the most complete option at the same price point as its competitors — native affiliate email automation, first-party-cookie tracking, and multi-platform billing support give it the widest room to grow without adding another tool.
- Native email automation for affiliate broadcasts and drip campaigns, no separate tool required
- First-party-cookie tracking for more dependable referral attribution
- Supports Stripe plus other payment platforms rather than a single-billing lock-in
- No permanent free tier, only a 14-day trial
- More configuration surface than Rewardful, which can slow a first-time setup
- Entry tier caps at $5,000/mo in affiliate-driven revenue before requiring an upgrade

Frequently Asked Questions
What is the cheapest affiliate software for a new SaaS company? +
Rewardful, FirstPromoter, and Tolt all start at the same $49/mo price point for their entry tier, so cost isn't the deciding factor between them. The better question is which billing platform you use and how much affiliate email/reporting depth you need — Rewardful is the simplest Stripe-only option, while FirstPromoter and Tolt offer more built-in features at the same price.
Which affiliate software supports billing platforms other than Stripe? +
Tolt natively syncs with Stripe, Paddle, and Chargebee. FirstPromoter also supports multiple payment platforms. Rewardful is Stripe-only with no native support for other billing providers.
Do any of these tools charge a percentage of affiliate sales? +
No. All three — Rewardful, FirstPromoter, and Tolt — charge a flat monthly subscription fee with 0% transaction fees on affiliate-driven revenue. Pricing scales by how much monthly revenue your affiliates generate, not by a cut of each sale.
