Evaluating Vendors

8 min read

Beyond the Feature List

Features are important, but they are only one dimension of vendor evaluation. Pricing structure, contract flexibility, support responsiveness, and API capabilities directly affect your total cost of ownership and your ability to operate the platform effectively. A platform with strong features but poor support or rigid contracts can become a liability.

Pricing Models

ModelHow It WorksWatch Out For
Flat monthly feeFixed price regardless of volumeMay not scale well -- check if pricing tiers increase significantly at higher volumes
Per-conversion feeCharge per tracked conversionCosts increase directly with program growth -- calculate projected costs at 2x and 5x current volume
Revenue shareVendor takes a percentage of affiliate-generated revenueAligns incentives but can become expensive as revenue grows
HybridBase fee plus per-conversion or volume-based componentMost common for mid-to-large programs -- understand both components clearly
Setup feeOne-time implementation chargeNegotiate this based on migration complexity -- some vendors waive it for multi-year contracts

Contract Terms to Review

  • Contract length: Monthly, annual, or multi-year? What are early termination penalties?
  • Data ownership: Who owns the tracking data? Can you export all data if you leave?
  • SLA commitments: What uptime guarantees exist? What compensation is offered for downtime?
  • Price lock: Are prices locked for the contract term, or can the vendor increase mid-contract?
  • Auto-renewal: Does the contract auto-renew? What is the notice period for non-renewal?
  • Data portability: What format can you export data in? Is there a charge for data export?

Support Quality Assessment

  • Response time: What is the average response time for support tickets? Get this in writing.
  • Dedicated account manager: Do you get a named contact, or general support queue?
  • Technical support depth: Can support help with API integration, custom configurations, and data issues?
  • Onboarding support: What does the vendor provide during implementation? Training? Data migration assistance?
  • Documentation quality: Is the knowledge base comprehensive and up to date?

API Capabilities

  • API coverage: Can you access all core functions (partner management, reporting, commission data) via API?
  • Rate limits: What are the API call limits? Are they sufficient for your integration needs?
  • Webhook support: Can the platform push events (new conversion, payout processed) to your systems?
  • Documentation: Is the API well-documented with examples and SDKs?
  • Versioning: How does the vendor handle API version changes? Is there a deprecation policy?

Reference Checks

Ask the vendor for references from operators in your vertical. Speak to existing customers about their experience with support, uptime, and how the vendor handles issues. Ask specifically about the migration experience if they switched from another platform.

Request a trial or proof-of-concept period before signing a multi-year contract. A 30-60 day trial with your actual data and workflows reveals issues that demos and sales presentations do not.

Key Takeaways

  • Evaluate pricing models at projected growth -- calculate costs at 2x and 5x current volume
  • Review contract terms for data ownership, SLA commitments, price locks, and termination clauses
  • Assess support quality through response time commitments, dedicated contacts, and documentation
  • Test API capabilities against your integration requirements before committing to a vendor
