Pricing is product strategy. Free lowers barriers but costs support—tiered usage or feature-gated free. Value-based pricing: what is this worth to users? Many products under-price, especially to start.
Structure: per-seat works for collaboration, per-resource makes sense for consumption, flat fee is simplest. Include tiers for different budgets: individual, team, enterprise with SSO and support.
Value metrics: time saved, revenue generated, risk reduced. Test pricing with users—surveys for willingness to pay at different price points. Raise prices carefully: warn existing customers, grandfather for a period.
