Earlier this year, Frontline Managed Services rebranded from Intelliteach to reflect the company's growth in administrative, financial and IT managed services. Now, the company is showing its growth in law firm back office activities in a new way: M&A activity.

Today, Frontline announced it has acquired InvoicePrep, an e-billing and invoice service for law firms. InvoicePrep provides both outsourced process work as well as workflow and invoice compliance & revenue management (ICRM) software to manage invoice compliancy to outside counsel guidelines.

InvoicePrep's capabilities will be married to Frontline's preexisting e-billing platform that launched in late 2019, which the company said processes more than 80,000 invoices a month. Frontline said the deal will also add 40 new law firm clients to the company.
