Immediate error message: "Tightly Lite is not open to [our website] yet." Cool story bro. I'd maybe be more generous with the review if there was any warning our shop couldnt sign up or even any reason given... Did i select the wrong thing? Who knows. Are they rejecting everyone this week? Hard to tell.

Toby and the team at Tightly have been amazing in getting the app configured for us whilst taking our feedback onboard on ways to improve the app over recent months. The app has so many amazing features, some that we've not had the capacity to fully utilise yet due to the complexities of our procurement across multiple brands, but at it's core it's days of cover feature is ensuring we're stocked...
