Starting or creating a family office
How Should a Family Track Setup Spending Against Its Approved Budget?
Short answer. Assign one person to maintain a simple setup budget, with a named approver for commitments and payments. Record each expense against its approved category and retain its supporting document. Compare actual and expected spending on a regular schedule. Escalate proposed changes before approval and keep a clear record of the decision.
Assign one person to maintain the setup budget, with approval required before the family commits to spending outside the agreed plan. This gives the family a clear record of costs as the office takes shape.
Set up the Budget Before Spending
Break the approved budget into practical categories, such as legal and accounting work, staffing, technology, office operations, and outside services. For each category, record the approved amount, expected timing, and person responsible. Define who can approve a purchase and who can authorize payment. When one person handles several duties, use a second reviewer for larger or unusual expenses.
Keep each commitment tied to its purpose. A proposal, engagement letter, purchase order, or invoice should identify the work or item, the expected cost, and the budget category. Retain the approval and supporting document with the payment record. If legal or tax treatment is unclear, consult your attorney or CPA before deciding how to record it.
Review Actual and Expected Costs
Update the budget as invoices arrive and commitments are made. Track actual spending, open commitments, and the remaining amount in each category. Compare the expected final cost with the approved amount, including cash already paid. This helps surface a cost increase while there is still time to adjust timing, scope, or the provider arrangement.
Schedule a regular review with the budget owner and the family member or committee responsible for oversight. Keep the discussion focused on differences: what changed, whether the work remains in scope, and whether another approval is needed. The family office cost calculator can help organize cost categories. For a broader view of how the office will operate, refer to fundamentals of creating a single family office.
Control Changes and Preserve the Record
When a new cost arises, document its reason, amount, timing, and funding source before approval. If the request changes the office's scope, take it back to the family for a decision. Show the effect on the total budget when adding new work to an existing category. A written change log makes it easier to explain why the plan moved and who authorized the change.
At each review, save the current budget and note the date and decisions made. Share the level of detail that fits the family's governance and confidentiality rules. If multiple family branches are involved, make sure the agreed process specifies how costs and approvals are reported. This practice gives the family a usable history when it reviews the startup plan, evaluates providers, or sets the operating budget.
