I recently submitted a manuscript in a reliable journal in my field through 'invited manuscript' scheme. This is my first time to do such a thing since I mostly publish my paper on a regular submission. Of course, in general, the paper will be accepted based on its quality and merit. But, I was wondering if there is a difference in the chance of getting published when the submission was invited?
In my experience from my own invited submissions to those of my colleagues' being invited means the journal trusts you to produce something worth publishing. Therefore, unless you mess things up, your manuscript should be easily accepted for publication.
However, that means you should be extra careful. Your public exposure relies on your publication record. You don't want to look bad. So make sure (i) the journal is truly respected in the area; (ii) nothing silly gets published. There is a tendency to slacken peer review whenever authors are invited to submit, meaning overlooked mistakes may more easily make it to final publication version. I'd recommend you find yourself one very picky colleague to peer review your manuscript on the side, prior to submission.
