Frequently Asked Questions (FAQs)

❓ How much does a professional case study cost?

Short (500 words, basic): $500–$1,500. Standard (1,500 words + design): $2,500–$5,000. Premium (3,000 words + video + graphics): $5,000–$15,000. Volume discounts for 5+ case studies (20–30% off).

❓ How long does it take to write a case study?

Customer identification: 1–2 weeks. Interview scheduling: 1–2 weeks. Writing: 5–7 days. Approval & legal: 1–2 weeks. Total: 4–8 weeks for a single case study. Rush (2–3 weeks) costs 50% more.

❓ Should I use a template or custom design for case studies?

Template: faster, cheaper, consistent brand. Custom: more engaging, memorable, but expensive. Many B2B companies use templates for 80% of case studies and custom design for their top 20% highest-value customers.

❓ What makes a case study effective?

Effective case studies: specific metrics (not "increased sales" but "increased sales by 143% in 6 months"), genuine quotes from real customers, a clear before/after narrative, and a relatable customer profile. Bad case studies: generic fluff, no numbers, obvious self-praise.

❓ Do I need customer permission before writing a case study?

Yes — written permission. Some customers require legal review and approval of the final draft. Offer incentives: discount, gift card, charitable donation, or public recognition. Never publish a case study without signed release form.

❓ Where should I publish case studies?

Sales enablement: private portal (accessible only to sales team). Public website: for SEO and social proof. Both have value. Many B2B companies publish high-level summaries publicly and keep detailed metrics for sales.

❓ How many case studies do I need?

Minimum: 3 per major product/industry. Best practice: 5–10 case studies across different customer segments. Enterprise B2B may need 20+ case studies for different verticals, use cases, and buying personas. Quality matters more than quantity.

❓ Should case studies be written in first person (customer) or third person?

Third person (company perspective) is standard B2B format. First person (customer quotes) works for testimonials. Hybrid: third-person narrative with first-person quotes. Avoid pure first-person — can read like an unprofessional testimonial.

❓ What if my customer won't share exact metrics?

Use ranges or percentages instead of raw numbers ("increased efficiency by 40%"). Use directional language ("significant reduction"). In competitive industries, some metrics must be anonymized. Focus on what they will share.

❓ Can AI write case studies?

AI can format notes into draft paragraphs, but cannot conduct the customer interview, extract genuine emotion, or verify metrics. Case studies require human curiosity and relationship-building. Use AI for editing; use humans for interviewing and storytelling.
