Billing for law and accounting firms
Every billable minute, on the invoice
ModusBill turns time entries, flat fees and retainers into invoices your clients can pay online. Law firms get IOLTA trust accounting that reconciles and LEDES export; accounting firms get recurring billing and a QuickBooks Online connection. Both get the A/R reporting a practice actually needs.

What is ModusBill?
Billing software for law firms and accounting firms
ModusBill is professional services billing software for law firms and accounting firms. It records time, flat fees and expenses against matters or engagements, turns the work into invoices clients pay online, bills standing charges on a schedule, imports data from other billing systems, and reports A/R aging. Law firms add IOLTA trust ledgers that reconcile three ways every month and LEDES 1998B export; accounting firms connect QuickBooks Online so invoices and payments stay in step. English and Spanish, priced per user per month with a 30-day free trial.
Built for the way firms bill
One system from the first time entry to the cleared payment
Not a generic invoicing tool with a professional skin. Matters and engagements, client trust ledgers, billing roles and electronic billing formats are the model, not an add-on.
Time and billable hours
Capture time against a matter as the work happens. The billing desk can revise billable hours before an invoice goes out, with the original entry left intact.
Flat fees and retainers
Bill a fixed scope as a flat fee, or transfer earned fees out of a client's trust balance — every movement recorded, the balance always current.
IOLTA trust accounting
Client ledgers that can never go negative, an audit trail nothing can edit, and three-way reconciliation against the bank statement every month.
Invoices clients can pay
Generate the invoice, email it, and give the client a secure link that opens the bill and takes payment — no account, no portal password.
Online payments
Stripe and PlaceToPay are wired in per firm. Payments land back on the invoice automatically, so the A/R you look at is the A/R you have.
LEDES electronic billing
Export LEDES 1998B for insurers and corporate clients that will not accept a PDF — from the same invoice, without rekeying a line.
QuickBooks Online
Invoices, customers and payments raised in QuickBooks appear here, payments you record here go back to QuickBooks, and the invoices you raise here can be posted there as you send them — so the same bill never reads as open in one place and paid in the other.
Recurring billing
Monthly bookkeeping fees, retainers and any standing charge raised on schedule as draft invoices, ready to review before they go out.
English and Spanish
Each user works in their language and each client is billed in theirs — the invoice email follows the client, not the sender.
How bilingual billing worksTwo trades, one system
Built for law firms. Now for accounting firms too.
The same billing engine underneath, with the words and the specialist pieces following your practice. Nothing to migrate between and nothing extra to buy.
Law firms
Work is organized by matter. Client funds sit in IOLTA trust ledgers that reconcile three ways every month, and invoices export as LEDES 1998B for insurers and corporate clients.
Accounting firms
Work is organized by engagement. Standing fees bill on a schedule, and a QuickBooks Online connection keeps invoices and payments in step with the books you already keep.
Time tracking, flat fees, expenses, online payments, recurring invoices, client and A/R reporting, imports, roles and bilingual invoicing are in both.
How it works
Four steps, and the month is billed
Set up clients and matters
Rates, billing type and language, per client and per matter.
Capture the work
Time entries, flat fees and trust deposits as they happen.
Review and invoice
The billing desk revises, approves and sends — PDF or LEDES.
Get paid
Clients pay online; the dashboard shows what is still out.
Pricing
Priced per user. Every feature in every tier.
The bands buy volume, not features. A three-person practice gets LEDES export and online payments on the same terms a forty-lawyer firm does — the only thing that changes as you grow is the seat price, and it goes down.
Pay for the year up front and every seat drops $3 a month — $36 a seat over the year, in every band. Every firm starts with 30 days free.
