Featured Reviews

ThomasPetrou - PeerSpot reviewer
Consultant at Mazi4u
Integration across functionalities has streamlined business operations and improved cost efficiency
Odoo's documentation needs improvement, as there are areas that are not well-documented. Additionally, some underlying technologies need refactoring to more modern structures. Although it's not immediately necessary since the system works, changes to the architecture would be beneficial. From the transition from version 17 to 18, it appears they are aware and have begun addressing some of these concerns.
Lowawot Alice - PeerSpot reviewer
Marketing Director at UPS
Targeted push campaigns have increased conversions and are driving more repeat customer purchases
OneSignal has positively impacted my organization by allowing us to reduce our cost of customer acquisition and increase our conversion rate from 40 to 65%. We have also increased our conversion rate to 30%. Additionally, OneSignal has allowed us to grow our number of subscribers organically, driving more website traffic and increasing sales engagement and campaigns from 50% to 65%. Since we are able to send more push notifications to our subscribers on their preferred device, we can reach out to them and they can see what we offer as services, enabling them to subscribe to our platform. This allows us to drive more website traffic, increase sales, enhance sales engagement, and drive more productivity. OneSignal offers the best features, including sending instant notifications without delay, providing all necessary features for testing, being highly cost-effective, handling huge volume efficiently, and providing great customer support.
