We rank platforms by their G2 average rating. A platform needs at least 50 reviews to be ranked, and ratings within 0.3 points are shown as a tier, not a strict order.
Our team scores each platform from 1 to 5 on coverage of this category, ease of use, integration with ERP and finance, total cost and value, implementation and support. The team ranking is the average.
