Cycle Count workflow

Hi

The clients wants a workflow for having a record of justification provided over the variance amount in in cycle count process.

They want a workflow to be triggered post cycle count update and approval . They don want it during approval as the acceptance may take up to 24 hours and they dont want the inventory to be inaccurate till approval. However, they would like to have a track of justification.

What they are now looking forward is that when the variance report is prrnted, depending on the %, the emails must be flowing to different levels.

Can someone suggest/throw some ideas on how we can achieve this
