It's Brian. I think there are a couple of factors that are involved. Primarily, I would say is Neighborhood and just the timing of us getting the cross-selling opportunities up and running that we talked about in the last call, basically got that started earlier in Q2. Keep that going, I think that provides the momentum in the back half of the year. But it will take some time for us to build, as well as changing kind of their overall strategy to be focusing more on the payers. That's what I should we just look at the top end of our guidance for Q3 here, $57 million would get you -- would force to get to $225 million means you probably have nearly $70 million in Q4, and that probably is just a little bit too high. But overall, we feel very, very comfortable with the $210 million to $220 million range.
And the good news I think with coming out of this quarter, is a couple of things. One, very clearly, we saw an acceleration of OmniPod in Q2, and it's clear that people aren't waiting overall, but we still believe, some are too. Right, so we are really encouraged, and I think excited by the level of referral demand that came in the door in Q2 and seeing investments in the commercial team started to pay off.
We are also very encouraged by the fact that we were able to start to build some gross margins in Q2, both on the back of the improved quality, as well as just the lot of work we have been doing around through the supply chain, and what it does is, regardless of the timing of the approval or not, we think we are so well on track to be able to hit our goal here of getting the premium cash breakeven by the end of the year.
So from that perspective, it certainly takes some of the pressure off of trying to get everybody converted over by the end of the year, and making sure that we couldn't do it.
Lastly, the fact that we have a little bit of additional time, I wouldn't underestimate the opportunity for us to be able to derisk this transition. It just gives that much more time for us to make sure everything across the manufacturing, the commercial, and the operational teams is ready to go.
