How We Rank
Rankings use a weighted review score that adjusts for review volume. A solution with a 4.5 rating from 200 reviews scores higher than one with 5.0 from just 2 reviews. The formula pulls low-review solutions toward the category average, so the ranking rewards consistent quality backed by real user feedback.
Rating source: All ratings come from IMDA’s SMEs Go Digital portal, submitted by businesses that used PSG to adopt these solutions. We do not add or modify ratings.
