Comparison
Excel is fine for arithmetic. Estate Metrics is for the harder job: keeping the money trail explainable, supported, and ready to hand to another person without a manual cleanup project at the end.
Excel is good at
Keeping a list of money movements
Estate Metrics is for
Keeping the story, support, and review trail with each transaction
That matters when
The estate has reimbursements, imports, missing proof, or another human reviewer
The numbers are there, but the reason behind a reimbursement is buried in memory.
The receipt exists, but it lives in a downloads folder with no durable tie to the row it supports.
The import was messy, but nobody can tell later which rows were fixed, skipped, or questioned.
The final handoff becomes a second project because the spreadsheet was never the actual review artifact.
The folder hunt for the right receipt.
The side document that explains weird transactions.
The "clean this up before we share it" sprint right before review.
The fragile handoff where another person gets rows, but not enough context to trust them.
No. A spreadsheet is often fine when you are just listing transactions. It gets fragile when you need proof, reviewer explanations, cleanup decisions, and a packet another person can trust without asking you to reconstruct everything.
Not raw arithmetic. It replaces the manual job of turning scattered transactions, receipts, notes, and cleanup choices into a review-ready estate record after the fact.
