E‑Billing & Spend Management
E‑Billing BEFORE THE INVOICE ARRIVES.
PERSUIT is the only e‑billing solution that delivers value and insight before the invoice is submitted — from scoping and pricing, to live WIP, to AI review at the point of billing. So when the invoice lands, you already know the answer.

The Key Difference
We start before the invoice is submitted.
If your e‑billing starts when the invoice arrives, you're already behind. PERSUIT begins the moment a matter is scoped. By the time you get the bill, the price is agreed, the budget is live, the WIP is visible, and the firm has already cleared its own invoice.
01 — Scope
Intake & scoping
The matter is defined before a dollar is committed. Scope, phases, and expected outcome are captured at inception.
02 — Price
RFP & pricing
Firms compete on price and approach. The agreed AFA, fixed fee, or rate card becomes the billing rule — automatically.
03 — Track
Live WIP
Unbilled time flows continuously from firm systems. You see exposure building — weeks before it becomes an invoice.
04 — Clear
BillClear
Firms see and fix flagged issues before submission. Compliance happens at the source, not in your inbox.
05 — Invoice
Where everyone else starts
By this point there are no surprises left. The invoice is a confirmation, not a discovery.
The Real Problem
Legal Ops doesn't hate e‑billing.
They hate what it
makes them do.
- —Explain budget overruns after the fact.
- —Manually chase firms for accrual estimates every month — and getting fiction.
- —Rate cards buried in PDFs, disconnected from enforcement.
- —Benchmarks that arrive as a static report months after the decision was made.
- —Act as the human middleware between procurement, finance, and outside counsel.
- —Tolerate systems that flag problems only after the invoice is already in.
Firms aren't careless. They're managing dozens of clients, each with different billing rules, accrual timelines, and OCG nuances. The system is broken — not the firms. PERSUIT fixes the system.
See the SolutionPersi — Built into PERSUIT
EVERY E‑BILLING VENDOR SAYS AI. WE SHOW IT.
Elsewhere, "AI" is a rules engine checking line items against a billing guideline. In PERSUIT, AI runs the length of the platform — you can ask your spend data a question in plain English and get an answer in seconds, and every invoice is read, reasoned over, and reconciled against what was actually agreed.
→Ask anything. "Which firms beat their budget on employment matters last year?" Answered instantly, from your own data.
→AI invoice review. Every line read against the agreed fee, the scope, and the guidelines — not just a keyword rule.
→Insight before you ask. Rate drift, budget risk, and anomalies surfaced while there's still time to act.
Smart agent. Wise counsel.

Persi — Working with you
We just got a $180K invoice from Nester Sotelo on the Meridian matter. Is this right?
Invoice validation completeThe agreed fixed fee was $155K. This invoice exceeds by $25K. The overage maps to 3 timekeepers billing at unapproved rates. Against benchmark, the fee still sits in the 71st percentile. I've flagged the line items and drafted a correction request. Want me to send it to the firm?

Benchmarking
EVERYONE WANTS BENCHMARKS. PERSUIT HAS THEM LIVE, INSIDE THE WORKFLOW.
The next-best systems sell you a static report — and only on hourly rates. PERSUIT benchmarks hourly rates and AFAs against $22B+ of real, competitively-bid proposal data, updated continuously and surfaced at the moment you're pricing a matter, approving a rate rise, or reviewing an invoice.

What Makes PERSUIT Different

PERSUIT controls
what happens.
Traditional e‑billing
✗
Value starts at the invoiceNothing useful happens until the money is already spent. By then, you've lost.
✗
Rate cards in PDFsDisconnected from enforcement. Agreed rates quietly drift per matter with no visibility until annual review.
✗
Accruals are educated guessesManual estimates from firms every month. Finance doesn't fully trust the numbers. Neither do you.
✗
Benchmarks as static reportsAn annual PDF on hourly rates. Nothing on AFAs, and nothing you can act on mid-matter.
✗
"AI" as a line-item checkerRules engines rebadged as AI. You still can't ask your spend data a question and get an answer.
✗
Firms must be policedAll the compliance work lands on Legal Ops.
✗
Built for hourly billingAFAs, fixed fees, and value-based arrangements are afterthoughts — shoehorned into systems designed around the billable hour.
PERSUIT e‑billing
✓
Value starts at scopingIntake, sourcing, pricing, guidelines, budgets, WIP, and billing — all connected. Commercial discipline from day one.
✓
Rates flow from RFP into e‑billingNo PDF graveyard. Agreed vs. actual is visible in real time, not at annual review.
✓
Continuous WIP from firm systemsAccruals reflect reality. Finance trusts the numbers. You know your total liability before invoices land.
✓
Live benchmarking on rates and AFAs$22B+ of real proposal data, in the system, at the moment of decision. Nobody else can benchmark an AFA.
✓
AI across the whole lifecyclePersi reviews invoices, answers questions of your spend data in plain language, and surfaces insight before you think to ask.
✓
BillClear makes compliance easy for firmsFirms correct invoices before submission. Value is captured without pushing policing work onto your team.
✓
Purpose-built for AFAs and value-based pricingFixed fees, capped fees, blended rates, success fees — tracked and enforced natively. Not bolted onto an hourly billing engine.
What Others Can't See
Agreed vs.
Actual.
Most enterprises agree on rates once a year and then hope they stick. PERSUIT makes hope unnecessary. Rates negotiated in the RFP flow directly into e‑billing enforcement. If a rate is overridden, it's visible. If scope expands, it's tracked. If volume discounts are promised, they activate.
This is the first time in legal ops history that the rate you agreed to and the rate you paid are the same number, in the same system, visible to everyone.

From Estimated Accruals to Actual Liability
IF YOU CAN'T SEE WIP, YOU CAN'T SPOT ANOMOLIES.
Month-end accrual calls used to mean chasing 15 firms for manual estimates — and getting educated guesses that made Finance nervous. PERSUIT connects directly to firms' time and billing systems. WIP is continuous, not periodic. You see what could be invoiced before it's invoiced.
Finance stops getting blindsided. Month-end close gets faster. And your credibility with the CFO goes up — because your numbers are real.

WE MAKE COMPLIANCE EASY FOR FIRMS.
01
Firms want to complyManaging 50 clients with 50 different billing rules, accrual timelines, and OCG nuances is genuinely hard. We automate the complexity so compliance happens by default.

03
AMLAW adoption at scalePERSUIT is already embedded with the firms you work with. Onboarding is measured in days, not quarters.
04
Panel strategy becomes data-drivenLive volume data activates promised discounts automatically. Panel decisions stop being guesswork.
Control the Narrative Before Finance Does
Activity metrics tell you what Legal did. Value metrics tell you why it mattered.
If Finance owns the spend story, Legal is reactive. If Legal owns it, Legal is strategic. PERSUIT gives you the numbers to own it.

Customer Stories
See how legal teams are taking control of spend.
Epiris
Epiris began using Apperio in 2018 and has found this to be a crucial tool in helping internal investment and finance teams to understand legal spend in greater detail and manage the external matters currently in progress.
Phoenix Group
The legal operations team at Phoenix Group used process and technology to control legal costs — and they did it in a way that supported the relationship among the in-house team and the company’s panel of law firms.
Cornerstone
Cornerstone is the UK’s leading mobile infrastructure services company. They acquire, manage and own over 20,000 sites and are committed to enabling best in class connectivity for over half of all UK mobile customers.
Network Rail (Panel reviews)
Network Rail were able to increase confidence in their legal teams by working with law firms who were able to operate with a more open and transparent mindset. Read how Network Rail halved the size of its external legal panel.
Network Rail
Network Rail were using billing reports which were three months out of date and therefore weren’t of strategic value. With real-time spend analysis, Network Rail were able to make better management decisions.
Financial Services Compensation Scheme
A household name in financial protection, the Financial Services Compensation Scheme was challenged in its forecasting, budgeting and decision-making by uncertainty over legal spend.
Trainline
Trainline’s use of Apperio led to the termination of one law firm which was consistently over-charging them.

Common Questions
We've heard the objections. Here's the honest answer.
"Is this real e‑billing, or light functionality?"
Real. The largest private equity firm in the world is a delighted customer. Full invoice processing, GL coding, matter management, budget tracking, and WIP visibility — not a lightweight add-on.
"Doesn't every vendor have AI now?"
Everyone says it. Ask for a demo of it. Ask whether you can query your own spend data in plain language, and whether the AI knows what was agreed at RFP. In PERSUIT it does — because the pricing and the billing live in the same system.
"We already get benchmarking reports."
On hourly rates, annually, as a PDF. PERSUIT benchmarks rates and AFAs against live competitive bid data, inside the workflow, at the moment of decision.
"Will my law firms actually adopt this?"
Yes — and they already have. PERSUIT has strong AMLAW adoption. BillClear makes compliance easier for firms, not harder. Onboarding is days, not quarters.
"Is this another system to integrate?"
No — it's done for you. PERSUIT handles the integrations. Your team is not the project manager. You're the beneficiary.
"Do we have to rip and replace our current system?"
No. But you probably should. Most teams run PERSUIT alongside existing tools first and migrate as confidence builds. The numbers usually make the case quickly.
