Billing syncs the moment you send
Every invoice created in LeanLaw posts automatically to QuickBooks Online as an Accounts Receivable transaction. Client payment terms, line items, and matter codes carry through exactly.
- Draft → approved → sent without double entry
- Matter codes map to QBO classes and customers
- Batch invoicing posts all matters at once
Collections post before you close the tab
Online payments, checks, wire transfers — every payment recorded in LeanLaw marks the QBO invoice paid and updates your AR aging in real time. E-payment processing included.
- Credit card and ACH payments via LeanLaw Pay
- AR balance updated instantly on payment receipt
- Trust-safe payment processing for retainers
IOLTA compliance baked in, not bolted on
Trust deposits, disbursements, and three-way reconciliation all happen inside LeanLaw and post correctly to your QBO trust liability account. Stay compliant without a separate system.
- Client trust ledger per matter
- Three-way reconciliation built in
- Disbursements post to operating and trust correctly

An Alternative to Legal Practice Management Software.
LeanLaw's integrations create an alternative to full-suite legal practice management software. Instead of forcing your firm into one platform that does everything adequately, combine the best-of-breed tools for each job — billing, accounting, and practice management — and connect them through LeanLaw.
Use only the tools that delight you.
Traditional Practice Management
One platform tries to handle billing, accounting, case management, document storage, and client communication — and typically does all of them at best adequately.
- Separate system from your accounting (QBO)
- Manual exports to sync financial data
- Pays for features your firm never uses
LeanLaw + QuickBooks Online

- Native two-way sync with QuickBooks Online
- Legal trust accounting built in (IOLTA compliant)
