Why billing needs structure?

Legal billing is more complex than standard invoicing. Retainers, milestone agreements, split costs, write-offs, and approval chains all create failure points when they are managed manually or across disconnected tools.

When billing is not structured, invoices are delayed, corrections become common, and collections slow down. The result is avoidable revenue leakage and more pressure on finance, partners, and billing staff at month end.

BizMagnet brings the full billing workflow into one controlled system so invoices are accurate, approvals are traceable, and collections are easier to manage.

How the billing workflow works with Legal Suite

How the billing workflow works:
The workflow is designed to move from matter activity to invoice posting with as little friction as possible.

1. Capture approved time and expenses

Time entries, expenses, and disbursements are pulled from the Legal Suite and linked to the correct matter and client record.

2. Apply the right billing method

The system supports retainers, milestone-based billing, split billing, and fee templates so different practice areas can bill in the format that fits the engagement.

3. Generate the draft invoice

Approved items are brought into a draft invoice that can be reviewed before posting. Finance and partners can check amounts, narratives, and write-offs before finalizing.

4. Review and approve

The draft-to-approval workflow ensures invoices move through the right sign-off stages before they are posted. This keeps the process controlled and auditable.

5. Post and recover

Once approved, the invoice posts into finance with the correct supporting detail, enabling collections, aging follow-up, and profitability tracking.

A practical example

Scenario

A firm billing a mix of retainer work and milestone-based advisory projects

The billing team had to manage retainers in one spreadsheet, milestone invoices in another, and approvals through email. When the invoice cycle hit month end, they spent hours reconciling billing details and correcting write-offs.

With BizMagnet, approved time and expenses are pulled directly into the draft invoice, retainer balances are visible in the system, and milestone billing is applied in the correct format. The result is faster invoice posting, fewer corrections, and cleaner recovery.
