| Revenue-cycle impact | Indirect | Direct through faster invoice and collections cadence |
| Attorney leverage | Higher on legal drafting and discovery | Higher on billing admin and follow-up |
| Best first hire | Drafting/discovery bottlenecks | Delayed invoicing and inconsistent collections |
| Workflow systems | Case/matter management | Billing, trust accounting, and finance handoffs |
| ROI timing | Throughput gains over matter lifecycle | Faster cash-flow improvements |
Verdict
If your attorneys are constrained by substantive case preparation, prioritize paralegal support. If cash flow is constrained by billing delays and collections lag, legal billing support usually delivers faster financial impact.
