I don’t think I need to update, as I only do budgeting in my client's files once. After it is complete, I do not review it again for that period.

If your clients have an Agrimaster subscription, but their budget is in a seperate file, this will need to be moved into the client’s Agrimaster.

They will then be able to share the file with you via File Manager and you will both be able to work in the file.
