Billing Model Terms
Per-Seat Pricing (Per-User Pricing)
You pay for each user who has access. Cost scales linearly with team size. Examples: Pipedrive Lite at $14/seat/month, HubSpot Starter at $20/seat/month, Salesforce Pro Suite at $100/seat/month. A 10-person team pays 10x the listed price.
Per-Contact Pricing
You pay based on how many contacts or subscribers you store. Cost grows as your audience grows. Examples: Mailchimp Standard starts at $20/month for 500 contacts and scales to $100+/month at 5,000 contacts. ActiveCampaign Starter is $15/month at 1,000 contacts.
Usage-Based Pricing
You pay based on consumption: tasks, operations, events, or credits. Examples: Zapier Professional at $29.99/month for 750 tasks. Make Core at $10.59/month for 10,000 operations. Pipedream Basic at $29/month for 2,000 credits.
Flat-Rate Pricing
One price regardless of users or usage. Predictable billing. Examples: Basecamp at $349/month for unlimited users. beehiiv Scale at $49/month for unlimited subscribers. Rare and getting rarer as vendors move to per-seat models.
Tiered Pricing
Multiple plan levels with increasing features and limits at each tier. The most common SaaS pricing structure. Examples: Pipedrive has 4 tiers from $14 to $99/seat. Notion has 4 tiers from $0 to Enterprise custom pricing.
Hybrid Pricing
Combines two models — typically a base fee plus usage or per-seat charges. Examples: HubSpot Professional charges $890/month flat plus $20/seat for additional users. Intercom charges $39/seat plus $0.99 per AI resolution.
Free Tier and Trial Terms
Freemium
A permanently free tier with limited features, designed to convert users to paid plans. Examples: HubSpot Free (unlimited contacts, limited features), Kit Newsletter (10,000 subscribers, no automations), ClickUp Free (unlimited tasks, 100MB storage).
Free Trial
Full access to a paid plan for a limited time (typically 7–30 days). Requires credit card upfront in many cases. Examples: Pipedrive (14-day trial), ActiveCampaign (14-day trial), Salesforce (30-day trial). NOT the same as a free tier.
Reverse Trial
You start on the full paid plan for free, then downgrade to a limited free tier when the trial ends. Designed to show you premium features before restricting access. Examples: Grammarly gives some Pro features before settling on Free (basic grammar, 100 AI prompts/month).
Lifetime Deal (LTD)
A one-time payment for permanent access. Common on AppSumo. Examples: TidyCal Individual at $29 one-time (vs. Calendly Standard at $12/user/month = $144/year). Risk: vendor may shut down or degrade the product over time.
Financial Metrics
MRR (Monthly Recurring Revenue)
The predictable revenue a SaaS company earns each month from subscriptions. Relevant to buyers because high MRR companies are less likely to shut down. Publicly traded SaaS companies report this in earnings.
ARR (Annual Recurring Revenue)
MRR multiplied by 12. The annual version. HubSpot reported over $2.4 billion ARR. Smaller tools may not disclose ARR. Tools with high ARR are generally safer long-term bets.
Churn Rate
The percentage of customers who cancel in a given period. High churn signals problems. Average SaaS churn is 5–7% annually for enterprise, 10–15% for SMB tools. Not published by most vendors.
MAU (Monthly Active Users)
Some tools charge based on unique visitors or active users rather than contacts or seats. Examples: Mixpanel and Amplitude use event-based pricing. Hotjar Basic is free for 35 sessions/day. This model is common in analytics tools.
Net Revenue Retention (NRR)
Measures revenue from existing customers including upgrades, downgrades, and churn. NRR above 100% means existing customers spend more over time. HubSpot and Salesforce both have NRR above 100% because of upselling.
Contract and Billing Terms
Annual Billing Discount
Most SaaS tools offer 15–30% savings for paying annually vs. monthly. Examples: Pipedrive Growth: $39/seat monthly vs. $29/seat annual (26% savings). Make Core: $10.59 monthly vs. $9/month annual (15% savings).
Auto-Renewal
Your subscription automatically renews at the end of the billing period. Most annual contracts auto-renew at current (not original) pricing. Salesforce, HubSpot, and most enterprise tools use auto-renewal by default.
Overage Charges
Fees charged when you exceed plan limits. Examples: Mailchimp charges extra for contacts above your tier. Zapier auto-upgrades your plan when you exceed task limits. Some tools (beehiiv Scale) have no overages — unlimited within the plan.
Grandfathering
Existing customers keep old pricing when a vendor raises prices. Typically lasts 1–2 renewal cycles. Ghost and Pipedrive both grandfathered existing users during recent restructures. Do not assume it lasts forever.
Seat Minimum
Some tools require a minimum number of paid seats. Examples: Monday.com requires a 3-seat minimum on paid plans ($14/seat = $42/month minimum). Salesforce sometimes requires annual commitments with seat minimums for volume discounts.
Fair Use Policy
An “unlimited” plan with undisclosed usage caps enforced at the vendor's discretion. Watch for this on “unlimited” plans. What “unlimited” really means: unlimited within reason, as defined by the vendor.
Frequently Asked Questions
Which pricing model is cheapest?
It depends on your growth pattern. Flat-rate is cheapest for large teams (Basecamp $349/month for unlimited users). Per-seat is cheapest for solo users (Pipedrive Lite $14/month). Usage-based is cheapest at low volume (Make Free 1,000 ops/month).
What does “contact” mean in per-contact pricing?
It varies by platform. Mailchimp counts every contact including unsubscribes and bounces. Kit counts only active subscribers. HubSpot counts marketing contacts separately from CRM contacts. Always check the vendor's definition — it directly affects your bill.
