Scalable payroll and HR that grows with the firm, backed by deep compliance tooling and support.

What is ADP?
ADP is one of the largest payroll and HR providers, and its ADP RUN product is built for small businesses while the broader platform scales all the way to enterprise. For a law firm that expects to add associates and staff, that runway means you are unlikely to outgrow it.
The draw for a practice is depth: full-service payroll with automatic tax filing, plus extensive HR, compliance, and reporting tools and access to dedicated support. That makes it a safe choice for firms that want one provider to lean on as headcount and compliance complexity grow.
This is an independent editorial overview, not legal or accounting advice, and inclusion here is not an attorney endorsement of the product. ADP is general business-payroll and HR software — it does not perform client-trust or IOLTA accounting, so your firm must keep client funds in dedicated legal trust-accounting software and follow your state bar's IOLTA rules.
ADP key features
Scales small to enterprise
ADP RUN starts small and the platform grows with the firm, so you don't have to switch systems as you hire.
Automatic tax filing
Full-service payroll calculates, files, and pays federal, state, and local payroll taxes for the firm.
Deep HR & compliance tools
Onboarding, reporting, and compliance support beyond basic payroll, useful as staff and rules multiply.
Dedicated support
Access to payroll and HR support so a small firm without an in-house specialist has a backstop.
Pros
- Scales from solo to large firm without changing systems
- Deep HR, compliance, and reporting tooling
- Automatic federal, state, and local tax filing
- Established provider with dedicated support
Cons
- Enterprise tiers are often quote-based, so pricing is less transparent up front
- More platform than a true solo may need or want to pay for
ADP pricing
ADP RUN uses tiered plans with pricing that frequently requires a custom quote, especially at higher tiers; setup fees may apply. Confirm current pricing on ADP's site.
Best for
- Firms that expect to grow headcount over time
- Practices that want deep HR and compliance support, not just payroll
- Offices that value a dedicated support relationship

ADP FAQ
Is ADP good for a law firm?
Yes, especially for a firm planning to grow — ADP RUN handles small-firm payroll today and scales into deeper HR and compliance tooling as you add staff. It is business payroll and HR only, so client-trust and IOLTA accounting still belong in dedicated legal trust software. Confirm current pricing on ADP's site.
Is ADP worth it for a small firm?
It can be if you value room to grow and strong HR and compliance support over the lowest price. A very small or solo practice that only needs basic payroll may find a simpler tool more economical.
How much does ADP cost?
ADP uses tiered plans and often quotes pricing per firm rather than publishing flat rates, and setup fees can apply. Request a current quote directly, since costs vary by employee count and feature tier.
