Inside CaseQube's Billing & Invoicing Engine: How One Pre-Bill Workflow Runs Hourly, Flat-Fee, Contingency, and Split Billing in 2026
💡 IN SHORT
CaseQube's billing engine runs every billing arrangement a firm uses — hourly, flat-fee, contingency, LEDES e-billing, split, and recurring — through one pre-bill review workflow, with each invoice posting directly to the general ledger. That means fewer disconnected tools, less billing leakage, and books that stay accurate the moment an invoice goes out.

Ask a mid-size firm how it bills and you rarely get one answer. Litigation runs on hourly, the immigration practice uses flat fees, the PI side is contingency, and corporate clients demand LEDES-formatted invoices through their e-billing portals. Most firms cover that spread by stitching together separate tools — and every seam between them is a place where time goes unbilled, costs go unrecovered, and the books fall out of sync with what was actually invoiced.

CaseQube's billing and invoicing engine was built to collapse those seams. Here is how it works and why running every billing type through one workflow matters more than firms realize.

💳 Every Billing Arrangement, One Engine

The engine doesn't treat billing types as separate products. They are configurations of the same workflow, so a firm can run all of them side by side without switching systems.

⏱️

Hourly Billing

Time entries flow from tracking straight into billing, with billable and non-billable clearly separated and rates applied by timekeeper and matter.

📦

Flat-Fee Billing

Fixed-scope matters bill on defined milestones or on completion — ideal for immigration, estate planning, and packaged services.

📈

Contingency Billing

Percentage-based fees calculate against settlement amounts and tie into settlement management for PI and mass-tort work.

🏢

LEDES E-Billing

Generate LEDES-formatted invoices that corporate clients' e-billing systems accept the first time, reducing rejections and appeals.

✂️

Split & Consolidated Billing

Split a single matter across multiple payers, or consolidate many matters onto one client invoice — without manual reassembly.

🔁

Recurring Billing

Automate retainer replenishment and subscription-style billing so recurring invoices go out on schedule without re-keying.

🔍 The Pre-Bill Review That Stops Leakage

Before any invoice leaves the firm, it passes through a pre-bill review — the single highest-leverage control in legal billing. Attorneys and billing managers see draft invoices in full, catch time that was never recorded, adjust or approve write-downs deliberately, and confirm costs are attached before the client ever sees a number.

💡 Pro Tip
Billing leakage is rarely one big miss — it is dozens of small ones: a 0.2-hour entry never logged, a $40 filing fee never posted. A disciplined pre-bill pass is where firms recover those, and it compounds into real money over a year.
⚠️ Watch Out
When billing lives in one tool and accounting in another, a write-down entered at pre-bill often never makes it to the books — so your revenue reports quietly overstate what you will actually collect.

🔗 Where the Real Advantage Lives: Straight to the General Ledger

This is the part standalone billing tools cannot match. In CaseQube, billing entries integrate directly with the general ledger — revenue accounts and billable expense accounts update as invoices are generated. There is no nightly export, no "sync to QuickBooks" job that fails silently, no reconciliation between what you billed and what your books say you billed. The invoice and the ledger are the same source of truth.

📊 Did You Know?
Because billing posts straight to the GL, a managing partner can pull matter profitability and realization the same day an invoice is issued — not after a month-end sync reconciles two systems.

⚖️ Why This Matters for the Modern Firm

A firm running four billing types through four tools spends its energy reconciling instead of collecting. CaseQube's engine means one workflow, one review step, and one set of books. Billing managers stop being data movers, the books stay current in real time, and no revenue falls into the gap between systems — because there is no gap.

✅ Key Takeaways
  1. CaseQube runs hourly, flat-fee, contingency, LEDES, split, and recurring billing through one engine.
  2. A mandatory pre-bill review is the highest-leverage control against billing leakage.
  3. Invoices post directly to the general ledger — no error-prone sync between billing and accounting.
  4. Real-time GL integration means same-day realization and matter profitability reporting.
  5. One billing workflow replaces the stitched-together tool stack most mid-size firms rely on.
