Business Model Slide: Pricing, Margins, Payback
Investors spend more time on the business model than almost any other slide. They want to know how you charge, what an account is worth, what it costs to serve and win, and whether customers pay more over time.
What should the business model slide show?
The business model slide should show how you charge (per seat, per use, flat tiers), average contract value, gross margin, what it costs to acquire a customer and how fast you earn it back, and how accounts grow over time. This slide gets more reading time than any other in DocSend’s seed deck data, summarized on the pitch deck template page, so make it easy to read in seconds.
What does a strong business model slide look like?
How do you explain your pricing?
Explain pricing in one line: what the customer pays for and how it grows with them. Investors want to see that price follows value, so the bill rises as customers get more out of the product. If you are still choosing a model, compare usage-based vs seat-based pricing and how to structure pricing tiers.
How should you show gross margin and unit economics?
Gross margin should include hosting, third-party software, AI model costs and customer support, not just servers. CAC should include salaries and tools spent on sales and marketing, not only ad spend. AI companies face extra scrutiny here; see the AI startup pitch deck. How these numbers grow over time belongs in your financial projections.
| Metric | Simple definition |
|---|---|
| Average contract value | Average annual revenue per customer |
| Gross margin | Revenue minus the cost of delivering the service, as a share of revenue |
| CAC | Total sales and marketing cost divided by new customers won |
| CAC payback | Months of gross profit from a customer needed to cover their CAC |
| Net revenue retention | Revenue from last year’s customers this year, including expansion and churn |
Price follows value.
Show that customers pay more as they get more from the product, and that each one pays back what it cost to win.
What if you are too early for unit economics?
Show what you can: the price customers have agreed to, paid pilots, and an honest estimate of acquisition cost based on founder time. Say clearly what is measured and what is assumed. The pre-seed pitch deck page covers early evidence, and CAC payback explains the calculation.
Frequently asked questions
What should be on a business model slide?
How you charge, average contract value, gross margin, customer acquisition cost and payback, and expansion.

Show contract value, gross margin, CAC and payback in a small table, today and at the next milestone.
What is a good gross margin for SaaS?
Software companies usually aim for high gross margins. Include every delivery cost, including AI model and support costs.
What is CAC payback?
The number of months of gross profit from a customer needed to recover what it cost to acquire them.
Should I include LTV:CAC in my deck?
Only if you have enough real retention data. Otherwise show CAC payback and early retention instead.
How do I explain usage-based pricing to investors?
Say what unit customers pay for, why it tracks value, and how average revenue per account grows.
What if I don’t have unit economics yet?
Show agreed prices, paid pilots and an honest acquisition cost estimate, labelled as early.
