He said, via BBC Sport: "We've got a lot of players out of contract, so we need to sit down and resolve that. Our first job is treating the out-of-contract players respectfully. Last year we didn't have many out of contract, but this year is different. Those talks are important and it is important that we get them done sooner rather than later."
Parkinson added: "I have been very much focused on the team and getting the job done, but naturally conversations are always going on about budgets, whatever division we were going to end up in and possible players. We are ahead of schedule on those discussions without a doubt. The planning for recruitment can start right away. So it is a really exciting summer that lies ahead of us. The massive challenge for us is can we build this squad strongly to challenge in League One, and I am really looking forward to taking on that challenge throughout the summer months."
