What is legal bill review?

Legal bill review is the practice of reviewing vendor law firms’ submitted invoices for billing errors to avoid overpaying for attorney fees, rejecting non-compliant line items and thereby reducing your company's outside counsel legal spend.

In layman’s terms, the legal bill review process mitigates the risk of overpaying for legal services and is crucial to enterprise legal management as it relates to containing outside counsel expenditure.

How do legal bill review programs work?

When reviewing a legal invoice for compliance, a billing error is determined to have occurred if a line item or time entry within the invoice is not compliant to billing guidelines agreed between a client and its law firm, or group of law firms.

In the event of billing errors being found through legal bill review carried out by LSG’s 10+ year PQE legal fee auditors, then invoice totals are reduced through a correction. This consists of adjusting the affected line item and notifying the law firm, in turn reducing overall legal spend and gradually improving compliance.

This is not the end of the process, however. At the time of notification, a law firm can choose to either accept a reduction or to go through dispute resolution if they feel a reduction has been made incorrectly. This stage should be equitable, and the law firms should feel fairly treated with all incorrect reductions reverted.

In the case of LSG’s programs, the end-to-end workflow of review, adjustment and dispute resolution is all handled by our team, with finalized legal invoices that are accepted by the law firms submitted into our clients’ AP for payment.

The legal bill review process is vital for legal spend management and reducing the cost of legal operations. LSG’s team of legal fee auditors specialized in legal bill review perform a comprehensive analysis of attorney fees and expenses across different jurisdictions, matter types and complexities.

What does legal fee auditing cost?

Typically, legal fee auditors charge a significant percentage (~2.5%) of each invoice for annual legal bill review programs. This gets expensive, and though legal fee auditing in itself saves you money over the course of a year, that’s no reason to overpay. We beat the price and performance of pre-existing vendors.

You will save money on pre-existing operational costs by choosing us as your legal fee auditor. Whether you have an in-house legal fee auditing team or already outsource, LSG can help you generate meaningful savings, beating the performance of our legal bill review competitors on both pricing and savings.

We offer multiple pricing models, ranging from percentage cost to flat fee and even hybrid models that include aspects of both. Our focus is on finding pricing that provides mutual benefit and clarity around legal invoice review costs.

As an example of how LSG’s legal fee auditors are deployed, we worked with a top 3 global P&C insurer to reduce their legal spend. Before working with LSG, the insurer was in a client relationship with one of our main competitors.

Switching to LSG saved the insurer an additional 2.9% on each invoice, culminating in total savings of 11.8%, an excellent result. In addition to this, however, we also priced our legal bill review more affordably, even with our improved performance over their previous attorney fee audit vendor.

The result for the client was ~7x ROI compared to the previous vendor’s ~3x ROI, resulting in a meaningfully higher bottom line profit improvement with LSG as their legal fee auditor on an annualized, real-time invoice review program.

How is legal bill review implemented?

PQE work to control your legal spend.

LSG’s legal bill review and legal fee auditing service can be used to analyze submitted invoices on clients’ pre-existing systems, or on our enterprise legal management software for ongoing litigation and/or for closed cases or matters.

What is a one-off legal bill audit?

Our legal fee auditing programs can be delivered as annual or one-off services, meaning that we can be brought in to audit a specific set of legal bills, e.g. for an M&A project, or we can review incoming legal invoices in real-time over the course of an annual legal bill review program. Annual programs are typically delivered through our enterprise legal management tool, ExpenseCore Legal.

Beyond scope and timelines, other differences between our legal bill review and legal bill audit offerings comes down to pricing. An annual program will typically be priced lower, meaning a lesser percentage cost of total legal spend, whereas a one-off legal bill audit will come in at a slightly higher percentage cost.

If you are interested in a more sporadic yet annual program of legal bill auditing, we also offer alternatives for you. Examples of relevant companies for this type of program includes frequent acquirers, with high legal spend during M&A events. In a program such as this, attorney fee auditing would be activated as needed.

With LSG, all options are competitively priced and clients can expect savings ranging from 6-11% of total legal spend on average. Historically, we’ve managed to achieve as high as 32% in savings, but it depends on the size of client and on the approach that is to be applied for the legal invoice reductions.

Frequently asked questions

Legal fee auditing services are priced on a percentage of legal spend. We offer a net savings guarantee and price beat guarantee. This means that you are guaranteed to save money with LSG’s legal fee auditing service, with cost reductions on pre-existing operations spend when switching from competitors or in-house to LSG.

Here's an overview of LSG vs. our competitors:
  • Bottomline Technologies - % of spend, e.g. 1.5-2%
  • LegalBillReview - % of spend, e.g. 1.5-2%
  • Wolters Kluwer - % of spend, e.g. 1.5-2%
  • LSG - guaranteed lower than competitors
We have had a legal bill review team, combined with an accompanying legal bill review software, for over a decade. This software has been implemented with various top companies around the world, ensuring maximum savings and near 100% compliant legal spend. The LSG legal bill review team utilizes this software, integrated with your incoming or pre-existing legal bills, and adjusts and approves invoices based on their compliance to agreed upon guidelines or SLAs with your suppliers and vendors. As an example, one of our insurance clients saved $522 million dollars over just three years using LSG's legal bill review service.
AI, or more aptly named machine learning (ML) for its use in legal bill review, compares newly submitted invoices against our proprietary database of invoices, which has already been processed by our legal bill review outsourcing team. If the newly submitted invoice has any line items that were previously rejected by a large portion of previously reviewed invoices, then machine learning would dictate a challenge to this legal spend. If this software does not detect non-compliant legal spend, then a recommendation is made to the human reviewer, the final sign off, that this invoice be approved as compliant.
LSG employs a best-of-breed legal bill review team, combined with a litigation management software to detect billing non-compliance, and areas where our clients are paying more than what’s fair. A recent average invoice savings example is 12%, which means 12 cents of every dollar back in that client's pocket. We also implement our proprietary best practices library, which consistently generates a savings “alpha” on top of any client billing guidelines.
Legal bill review services can be dovetailed into litigation management software and enterprise legal management software. These software platforms maximize cost containment as it relates to legal spend, and reduce not only legal bill values, but also time costs with an in-house team. The relevant in-house operations/finance team can be redirected to higher value add tasks for the business, for example, revenue generation opportunities. This subject might not get you overly excited, but it is important. To give some context, our legal bill review and ELM software combination generated ~$122 million in savings per year, in legal expenses, for just one client.
Legal bill audit is the process of auditing an organization's legal spend to ensure billing compliance to service level agreements and billing guidelines. In other words, legal bill review and legal fee auditing services ensures that companies do not overpay their law firms, and/or law firm panels.
