Advertising for SaaS companies

Acquisition cost is only meaningful against retention. A product with high churn cannot be marketed into profitability, however good the campaigns are.

Key points

  • Churn is a marketing constraint, not just a product metric.
  • Payback period matters more than cost per acquisition.
  • Onboarding is the highest-return marketing investment in most subscription businesses.

Subscription software has an unforgiving arithmetic. If customers leave after eight months and cost nine months of revenue to acquire, no amount of campaign optimisation makes the business work.

The numbers that govern the marketing

MetricWhat it decides
Monthly churnhow long a customer pays
Acquisition costwhat a customer costs
Payback periodhow long capital is tied up
Expansion revenuewhether accounts grow
Activation ratewhether trials become customers

Payback period is the operative constraint for most companies. At a twelve-month payback and 4 per cent monthly churn, the average customer barely repays their acquisition cost.

Fixing churn from 5 per cent to 3 per cent monthly increases customer lifetime by two thirds. No campaign change produces that.

Onboarding is marketing

The largest single lever on churn is what happens in the first two weeks. Customers who reach the point of value stay; those who do not, cancel.

Practical measures: identify the specific action that correlates with retention, then design everything to get new users to it quickly. Guided setup, sample data, a check-in at day three, and removal of every step that is not required.

Trial or demo

Self-serve trials suit products under a certain price where the value is demonstrable without help. Above that, a demo converts better because the buyer needs a conversation about their specific case.

Requiring a demo for a low-priced product loses the majority of interest. Offering a trial for a complex enterprise product produces trials that fail without support.

The content that works

Software buyers search for the problem, for alternatives to a competitor, and for comparisons. Three content types map to those.

  1. Problem content: how to solve the thing the software solves, including manually. It attracts people before they know software exists for it.
  2. Alternative pages: honest comparisons with named competitors, including where the competitor is better. These rank and convert unusually well.
  3. Integration and use-case pages: specific enough to match a specific search.

Pricing on the website

Hiding pricing behind a contact form is standard for enterprise software and costly for everything else. Buyers eliminate options they cannot price.

Where pricing genuinely varies, publish a starting figure and the factors that change it. Complete opacity loses more qualified buyers than a slightly wrong number.

Expansion is cheaper than acquisition

Revenue growth from existing accounts costs a fraction of new acquisition. Marketing to the installed base, so additional seats, additional modules, higher tiers, is usually underfunded relative to its return.

Frequently asked questions

What payback period is acceptable?

Twelve months or less for smaller businesses, up to twenty-four for enterprise with strong retention. Longer requires funding.

Should you offer a free trial or a demo?

Trial for self-serve products under a certain price, demo above it. Offering both usually dilutes each.
