With that urgency in mind
You could build a completely new field service solution from scratch customized to your needs. This would be a complex, time-consuming, and costly project. In addition, all investments made into your current solution would practically go to waste.
You can transition to the most advanced solution in the market: Salesforce Field Service. This solution was built by Salesforce using the original ClickSoftware engine. So, migrating to Salesforce seems like the logical next step. It’s also the faster solution allowing you to focus on what matters most and avoid working under pressure.
