A one-page finance memo for a spending decision

Open the memo with what the team is being asked to approve, the amount or range, and when a decision is needed. Explain the operational problem in concrete terms. A request to buy equipment that removes a documented production bottleneck is easier to evaluate than a claim that the purchase supports growth.

Name the owner and the scope of approval. Distinguish permission to investigate from permission to sign a contract or release money. Keep legal, security, and procurement reviews in the process where the commitment requires them.

Include deposits, installments, implementation, ongoing maintenance, training, cancellation terms, and other material costs supported by the proposal. Separate one-time and recurring amounts. The vendor's headline price may not describe the cash the business will commit.

For an illustrative $40,000 system with $8,000 of implementation and $1,000 monthly support, the first-year stated cost is $60,000 before other excluded costs. Put those amounts on their expected dates and show the effect on the approved cash forecast. Do not present $40,000 as the full decision.

Include a realistic do-nothing or defer option and at least one practical alternative where available. Explain the expected benefit, evidence, dependencies, and uncertainty for each. If a benefit relies on more sales, show the capacity and demand assumptions that connect the purchase to those sales.

A simple payback estimate can help, but it should not conceal timing, risk, or ongoing costs. Label illustrative calculations and test the assumptions that matter most. Avoid assigning a precise monetary value to an unmeasured benefit just to make the preferred option win.

Record the approval, conditions, budget owner, and review date. Choose observable outcomes such as reduced processing time, usable capacity, avoided cost, or completed delivery milestones. Keep the measure close to the reason the spending was approved.

After implementation, compare actual cost and outcome with the memo. Explain changes in assumptions and any additional commitments. A decision record is useful even when the result disappoints, because it lets the business improve the next choice without rewriting what was known at the time.
