For the user feedback trends sections, we performed a sentiment analysis of reviews left for each product from October 2018 to October 2020. Reviews data may have changed since publication and may not reflect current conditions.

For this report, we analyzed 83,965 reviews that mentioned ease of use across 310 billing and invoicing software products. To be considered for inclusion in this report, we required 20 or more unique reviews mentioning “ease of use” or related terms.

The products listed in this report had the highest percentage of positive mentions of ease of use functionality among eligible products.

To calculate the Sentiment Score, we looked at the specific mentions of ease of use in each review and analyzed the terms used to describe ease of use. We then scored each term on a scale of 0 to 10, with 10 being the most positive. The score for each snippet was the sum of all descriptive terms in the snippet. Snippet scores were then averaged for the product to determine average sentiment score for the product.

When comparing the average sentiment score of a product to the average score for the entire category, the product’s score was removed for accuracy.
