Variation Register
One row per change, the whole account in view.
Every change tracked from instruction to payment. One row per variation: who instructed it, in what form, what it is worth, its status and whether it has reached an application, so the account never has to be reconstructed at the end of the job.
What you get
An Excel template with no macros. Only the yellow cells can be edited, the Guide tab explains every step, and it prints on A4. Your contract's terms come first.
