Backed by machine learning, LSG's legal fee auditors meticulously identify instances of non-compliance, mathematical errors, and other issues. These flagged items undergo a second-layer human review during the legal bill assessment process. Only after this comprehensive review is completed is the invoice returned for either approval or appeal.

To date, LSG has saved its clients over $1.2 billion combined through AI-bill review services. Both annual bill review and one-off bill audit programs are available. Any program can be delivered through our automated platform, manually or through your existing system(s) if applicable.

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:

  • 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.
