Verified hours

Hours of professional work that were planned against real capacity, recorded as the work happened, and confirmed by the client along the way. Any invoice built on them traces back to work both sides already agreed on.

Definition

Verified hours are hours that satisfy three conditions at once:

  1. They were planned. The hours were committed in advance, inside the capacity the professional genuinely had that week, and the client could see the commitment.
  2. They were recorded as they happened. The time was logged during the work, not reconstructed from a calendar and memory at month-end.
  3. They were confirmed by the client. The business the work was delivered to signed off on the hours as they landed, before any invoice existed.

Hours that meet all three are a record. Hours that meet none of them are a claim. Most timesheets sit somewhere in between, and that gap is where hourly billing disputes, awkward month-end audits, and "is this really what we agreed?" conversations come from.

Why the distinction matters

For the professional

If you split your week across several clients, verified hours are how the retainer stays tied to a real slice of the week, how payment conversations stay short, and how a track record gets built. Confirmed hours are proof of reliability you can share with a prospective client without exposing who the work was for. They are also an early-warning system: when delivered hours keep beating planned hours, you are overcommitted, and the record tells you before a client does.

For the business

Your fractional CFO has other clients. So does your part-time engineer. Today you take it on faith that your hours fit into their week and that the invoice reflects what happened. Verified hours turn that faith into something you can check yourself: committed capacity you can see, hours confirmed as they land, and an invoice where every line reconciles. Approving it stops being an act of politeness.

How to prove hours worked to a client

"How do I prove I really worked these hours?" is one of the most common questions independent professionals ask, and the honest answer is that proof assembled after the fact is always weak. Screenshots, activity logs, and detailed narratives can be produced for hours that never happened, and clients know it. The reliable approach removes the need for proof:

  • Plan with the client before the work. A commitment both sides could see in advance is not something anyone has to prove later.
  • Record as you go. Hours logged during the work are accurate and specific. Hours rebuilt at month-end are approximate and, fairly or not, look like it.
  • Get confirmation along the way, not at invoice time. When the client has been confirming hours as they land, the invoice is the last step of a shared process rather than the first time they see a number.

Done this way, the question never comes up. The invoice explains itself.
