Introduction
In the competitive SaaS landscape, pricing strategy can make or break your business. According to a study by Price Intelligently, a mere 1% improvement in pricing strategy can yield an 11% increase in profits. Yet many SaaS companies still rely on guesswork or competitor benchmarking rather than data-driven pricing research. Two methodologies stand out for scientifically testing pricing strategies: monadic testing and sequential monadic testing. Understanding the nuances between these approaches can help you optimize your subscription pricing and maximize revenue potential.
What is Monadic Testing?
Monadic testing is a research methodology where participants are randomly assigned to evaluate only one pricing option. Each participant sees and reacts to a single price point or pricing structure, providing feedback without being influenced by alternative options.
Key Characteristics of Monadic Testing
- Isolated evaluation: Participants respond to a single pricing variant
- Reduced bias: No comparison to other price points influences the decision
- Clean data: Results represent genuine market reactions to specific price points
- Larger sample size requirement: Each pricing option needs its own statistically significant group
For SaaS companies, monadic testing provides clarity on how the market perceives individual pricing tiers or strategies. For example, a company might test a $49/month pricing plan with one group and a $79/month plan with another, measuring conversion rates and perceived value for each independently.
What is Sequential Monadic Testing?
Sequential monadic testing builds upon the standard monadic approach by exposing the same participants to multiple pricing options in sequence. After evaluating one option completely, participants move on to the next, creating a series of isolated evaluations.
Key Characteristics of Sequential Monadic Testing
- Multiple exposures: The same participants evaluate multiple pricing options
- Controlled sequence: Each option is evaluated fully before moving to the next
- Reduced sample size: Requires fewer total participants than standard monadic tests
- Risk of order bias: The sequence can influence perception, though this can be mitigated
Sequential monadic testing has gained popularity in SaaS pricing research because it provides comparative data while maintaining some of the benefits of isolated evaluation.
When to Use Monadic vs. Sequential Monadic Tests
Best Use Cases for Monadic Testing
Testing radically different pricing models
When evaluating fundamentally different approaches (e.g., per-user vs. tiered pricing), monadic testing prevents confusion and cognitive overload.When precision is paramount
For mission-critical pricing decisions affecting your core business model, the cleaner data from monadic testing provides higher confidence.When you have access to large sample sizes
Companies with significant traffic or large customer research panels can leverage pure monadic testing effectively.
According to ProfitWell, companies that use properly designed monadic pricing tests see a 15-30% higher price optimization outcome compared to those using basic A/B testing approaches.
Best Use Cases for Sequential Monadic Testing
Limited access to participants
Most SaaS companies don't have unlimited access to potential customers, making sequential monadic testing more resource-efficient.When comparing similar pricing tiers
When testing variations within the same pricing model (e.g., different feature allocations across tiers), sequential monadic can be effective.Gathering comparative feedback
If you want both isolated reactions and eventual comparisons between options, sequential monadic provides both datasets.
Implementation Strategies for SaaS Pricing Experiments
Setting Up Effective Monadic Tests
Define clear pricing hypotheses
Before testing, articulate specific hypotheses about how different price points or structures will perform.Randomize participant assignment
Ensure participants are randomly assigned to different pricing variants to prevent selection bias.Establish consistent evaluation metrics
Measure the same data points across all test groups: conversion rates, perceived value, willingness to pay, etc.Control external variables
Keep all other aspects of your offering consistent, isolating price as the only variable.
Setting Up Effective Sequential Monadic Tests
Randomize the sequence
To mitigate order bias, vary the sequence of pricing options shown to different participants.Allow complete evaluation
Ensure participants fully evaluate each option before moving to the next.Include cooling-off periods
Introduce brief breaks or distraction tasks between pricing evaluations to reduce the comparison effect.Gather both immediate and comparative feedback
Collect isolated responses after each option and comparative feedback at the end.
Common Pitfalls in Pricing Research
Both testing methodologies can fall prey to several common mistakes:
Insufficient sample sizes
Pricing tests require adequate statistical power. According to Price Intelligently research, most SaaS pricing tests need at least 100 qualified responses per pricing variant tested.Testing with the wrong audience
Ensure your test participants match your target market. Testing with current users only can create survivorship bias.Overemphasis on willingness-to-pay metrics
While important, willingness-to-pay should be balanced with perceived value, feature priorities, and competitive positioning.Ignoring qualitative feedback
The "why" behind pricing reactions is as important as the quantitative results.
Case Study: How Intercom Optimized Their Pricing
In 2018, Intercom conducted a comprehensive pricing research initiative using a hybrid approach. They began with monadic testing of core pricing models, followed by sequential monadic testing of specific tier structures.
Their research revealed that their target market preferred a usage-based component for messaging volume combined with feature-based tiers—insight they wouldn't have discovered with simple A/B testing of their existing model. The result was a 30% increase in annual contract value for new customers without negative impact on conversion rates.
A/B Testing vs. Pricing Research Methodologies
While many SaaS companies default to A/B testing for pricing, it's important to understand its limitations compared to structured pricing research:
A/B testing shows what happens, not why
While conversion data is valuable, it doesn't reveal underlying price perceptions.A/B tests can damage brand perception
Showing radically different prices to different segments can create trust issues when discovered.Limited context for decision-making
Traditional A/B tests don't capture qualitative feedback about value perception.
