    Frequently asked questions.

    What is law firm accounting?

    Law firm accounting refers to the specialized accounting processes used to manage the financial activities of a law firm. It involves tracking and organizing the firm’s finances, ensuring compliance with legal and regulatory requirements, and providing accurate financial reporting to partners, managers, and stakeholders. 

    What is the difference between law firm accounting and trust accounting?

    Law firm accounting is related to the business accounting of the practice, including trust accounting. It also incorporates financials such as income, expenses, overhead costs, etc.  Trust accounting is more specific to the management of client funds that are entrusted to the firm. They can hold onto these funds for external payments, such as legal fees and settlements. Trust accounting funds must be managed separately from the office accounting to ensure compliance with local, state and national bar association compliance, including IOLTA and IOLA programs. 

    Why does my practice need law firm accounting software?

    Legal accounting software provides law firm owners with one place to manage their finances. CosmoLex’s accounting software for small law firms efficiently organizes and streamlines financial transactions. This increases efficiency across other law firm functions, including legal billing, legal time tracking, and trust accounting. 

    How will using CosmoLex’s law firm accounting affect my clients?

    CosmoLex is designed for attorneys and law firms, but it has major benefits for clients, too. When you use CosmoLex to manage your business accounts, you improve the client experience from your first touchpoint to your last. CosmoLex’s automation and client management tools help firms streamline client intake, making the process fast and seamless with features like secure document sharing and e-signature.  During representation, clients access a secure client portal where they can message their attorney, send and view important documents, and access their billing reports. CosmoLex also enables clients with the option to pay invoices via credit card or online, improving law firm accessibility and boosting client convenience. Law firms can create professional-looking invoices and email them to clients in one click, helping clients get their bills paid by their due date. They can even use the accounting software to send automatic late payment reminders to past-due clients to help clients stay on track with payments throughout their matter.  CosmoLex is the only end-to-end practice management solution for matter management, firm accounting, and more.   

    What makes CosmoLex’s law firm accounting software different from other apps?

    CosmoLex’s law firm accounting software stands out because it is specifically designed to meet the unique financial and compliance needs of law firms. Unlike generic accounting apps, it combines legal-specific features like trust accounting, three-way reconciliation, and matter-based billing in a single platform. By integrating accounting, billing, and practice management, CosmoLex eliminates the need for multiple tools, ensuring compliance and streamlining law firm operations. 

    Does CosmoLex Integrate with QuickBooks?

    Yes, CosmoLex offers a QuickBooks Online integration for law firms on Core and Pro pricing tiers. This option is designed for firms that need to keep their existing QuickBooks setup, such as those working with an outside accountant who uses QBO. When the integration is enabled, data flows in one direction from CosmoLex to QuickBooks Online, and CosmoLex's built-in Business Accounting and Matter Budgets features are unavailable. For firms without a specific QuickBooks requirement, CosmoLex's native accounting remains the recommended path.
