The integration between our two platforms was seamless! They have built out their capabilities such as scheduling, performance management etc so well it's made life easier in all aspects - from onboarding new employees through promotions & appraisals right up until retirement planning!! There are no downsides I can think about except maybe there aren't any features we need now but if they were added later then perhaps those would be good too :) Give them some time though because things take longer than you expect sometimes due to how busy everyone keeps getting haha! Great team who listen very carefully when asked questions which makes communication easy especially via phone or email (we're located overseas). We've been able solve problems quickly using tools like Zapier where needed instead having go back into emails/docs ourselves. This has saved us loads of admin hours over previous manual processes used.
