Fix the engagement. The billing takes care of itself.
Between AI, board scrutiny, and CFO accountability, the pressures and challenges in-house teams face have intensified over the past couple of years, but the legal ops playbook hasn't kept up.
The industry still leads with e-billing — tools built for a world where the biggest problem was invoice compliance, not proactively controlling costs, or adding predictability and justifying every dollar spent.
But focusing on the end of a matter only lets you look backward. Turns out, the leverage was always upstream at inception and scoping the work to be done. It just wasn't where the market was selling.
The invoice isn't the problem. It's where the problem is revealed.
I've sat on both sides of the table as both a BigLaw partner and now at PERSUIT, and here's what I know: The problem is not the invoice. That's just the bill that came due on a decision that was made (or never made at all) weeks or months earlier, before the firm even started the clock.
Even if you moved to an AFA, a fixed fee on an undefined scope isn't predictability, it's just a different kind of surprise. The fee structure changed. The conversation that had to happen before it all started didn't take place.
AI is making all this harder to defer. In-house teams are now expected to absorb work that used to go outside, which means the engagement decision has changed. It's no longer just which firm at what price. It's whether the matter should go out at all, and if so, on what terms. And once it’s out to a firm or ALSP, how are their AI efficiencies delivering value.
Shifting governance from invoice to inception makes sure those questions get answered rigorously, and not retroactively.
Your immediate objections are understandable
Now, I know what you're thinking.
- You have billing guidelines
- Scope changes because the business changes
- Firms will resist this
That’s fine, but:
Billing guidelines tell firms how to bill. They don't define what changes the scope (or the price) of a specific matter before work begins. That conversation has to happen earlier, and it has to be matter-specific.
Scope isn’t meant to be set in stone, it's to agree in advance on the framework for how changes get priced. Scope creep is real. Almost guaranteed. Have a plan for it before the firm starts, not after the invoice lands.
Would you ever refuse to build your house with a fixed price contract because you know there are going to be variations? Of course you wouldn’t. You would fix the price and set the framework for how variations get priced. Same thing for legal services.
And yes, some firms will resist this because firms benefit from undefined scope. But the teams who've solved it use the engagement process itself to find out which firms will commit to defined terms and which won't. Ambiguity-dependent firms self-select out faster than you'd expect.
Perfection isn't the goal here. You don’t have to predict the future. You're eliminating the ambiguity that makes the future expensive and full of unwelcome surprises.
What earlier actually looks like
The teams doing this well describe it the same way. As one GC recently told me:
"No one understands our business better than we do. So the journey starts at matter inception — understanding the assumptions, agreeing on strategy, setting the right price. And it runs all the way through to billing. If our assumptions were wrong, we’ve set the framework for how to price the change. If they were right, I expect the matter to come in at the budget price."
That's the whole argument. Assumptions agreed upfront, tracked through to close, creating a virtuous cycle designed for continuous, real-time improvement.
The teams that Finance trusts aren't better at billing, they simply built a better beginning.
So ask yourself honestly: when was the last time a matter went out with scope defined, outcomes agreed, fee terms locked, and a framework in place for how changes get priced — before the firm started work?
If you can't answer that, you're not dealing with a billing problem. You're dealing with a governance problem that keeps showing up at invoice. And it will keep showing up there until the process changes at the beginning.
