Legal Spend Close: A 30 Minute Monthly Review for In-House Teams
Most legal teams review invoices one at a time. An invoice comes in. Someone looks at it. It gets approved. Then the next one. Over time, that approach creates a gap.
You know what you’ve approved, but you don’t have a clear view of:
what actually happened this month
what changed from last month
what’s likely coming next
And eventually, that gap shows up in a familiar moment Finance asks a question you can’t easily answer.
That’s where a simple monthly legal spend “close” can make a big difference.
The problem: visibility breaks down over time
Even with careful invoice review, most teams struggle to answer basic questions like:
• Why was spend higher this month?
• Which matters are driving cost?
• Are we tracking to budget?
• What should we expect next month?
Without a consistent review process, the answers are usually:
• buried across invoices
• spread across email threads
• or based on rough estimates
That makes it harder to:
• communicate with finance
• manage budgets
• spot issues early
A simple solution: a 30 minute monthly review
You don’t need a complex system to improve visibility.
A short, structured review once a month is usually enough.
The goal isn’t perfection, it’s clarity.
Here’s a simple way to run it.
Step 1: What happened this month?
Start with a quick snapshot.
Look at:
• total spend for the month
• spend by firm
• spend by matter (or matter type)
You’re not looking for detail yet, just a sense of scale and distribution.
Questions to ask:
• Does anything look unusually high or low?
• Are a few matters driving most of the spend?
• Does this align with expectations?
Step 2: What changed?
Next, focus on movement.
Compare this month to the prior month (or recent average).
Look for:
• spikes in specific matters
• new matters that weren’t present before
• changes in firm activity
• shifts in staffing or rates
This is where many issues first become visible.
A single invoice might not stand out. A trend across a month usually does.
Step 3: What’s coming next?
This is the step most teams skip, and where a lot of value comes from.
Try to estimate what’s ahead:
• outstanding invoices that haven’t arrived yet
• expected work in active matters
• upcoming milestones (filings, deals, negotiations)
If you track accruals, this is where they fit in.
Even a rough estimate is useful.
The goal is to avoid surprises, not predict perfectly.
Step 4: Is there anything to act on?
Finally, identify follow-ups.
For example:
• invoices that need clarification
• patterns you want to discuss with a firm
• matters that may be trending over budget
• staffing or billing issues you’ve noticed
You don’t need a long list.
Even one or two actions per month can have a meaningful impact over time.
What this actually changes
A monthly review like this does a few things quickly.
It makes it easier to:
• explain legal spend to finance
• spot issues before they compound
• build more accurate budgets
• feel in control of spend rather than reactive to it
Just as importantly, it creates a consistent rhythm.
Instead of reacting to invoices, you’re stepping back and looking at the full picture.
A simple example
Without a monthly review:
You approve invoices throughout the month, and at the end, spend feels higher than expected, but it’s not clear why.
With a monthly review:
You notice that one matter drove most of the increase, and that activity ramped up earlier than expected.
That gives you a chance to:
• explain the change internally
• adjust expectations
• or follow up with the firm if needed
The difference isn’t more work, it’s better visibility.
A simple place to start
If you want to try this:
Block 30 minutes at the end of this month
Pull your recent invoices or spend data
Walk through the four steps above
That’s enough to get started.
You can refine the process over time.
