description: Use when a law firm needs to check and report on client advance retainer or e-wallet balances — displaying the current retainer balance held in trust, recent debits and credits, projected runway at current burn rate, and generating a top-up request email when the balance falls below the replenishment threshold. Must be used with trust-account compliance rules (IOLTA / client money rules); see the related trust-account-reconciliation skill for compliance layer.

eWallet / Advance Retainer Balance Checker

A client e-wallet or advance retainer is funds held by a law firm on behalf of a client, to be applied against future fees as they accrue. The firm holds these funds in a client trust account (IOLTA in US; client account in UK; separate trust account per most professional conduct rules worldwide). This skill monitors the balance, forecasts runway, and automates top-up requests.

When to use this

• A client is on a retainer arrangement and the firm needs to monitor available funds
• Before preparing an invoice, to check whether the retainer covers the bill
• When a billing partner wants to see all retainer balances across their portfolio
• Automating a weekly or monthly retainer check as part of the billing pipeline

Trust Account Compliance — Non-Negotiable Principle

Client retainer funds held in advance are the client's money until earned. They must be:

• Held in a separate client trust account (not commingled with firm operating funds)
• Applied to invoices only when the invoice is approved and sent to the client
• Returned to the client if unearned when the engagement ends

This skill does not handle the trust account itself — it reports on balances. For the compliance layer (IOLTA reconciliation, client money regulation), see the related trust-account-reconciliation skill.

Runway Analysis

The runway calculation forecasts how long the current balance will last at the current burn rate:

Runway (months) = Current balance ÷ Average monthly billing rate

Average monthly billing rate = [Total fees in last 3 months] ÷ 3

A projected runway of less than 4 weeks should trigger an immediate top-up request. Runway calculations should account for any pending invoices already prepared but not yet applied.

Integration with Invoice Pipeline

Before generating and sending an invoice, check the retainer balance:

1. Balance sufficient: apply the invoice against the retainer; debit the client's ledger; notify the client of the application and remaining balance in the invoice cover email
2. Balance partially covers invoice: apply the available balance; issue the invoice for the difference; request a top-up simultaneously
3. Balance insufficient: issue the invoice as normal; send the top-up request; do not hold the invoice pending the top-up (client should receive the invoice promptly)

Time Since Last Top-Up

Track the time elapsed since the last retainer replenishment. If a client has not topped up in more than [60 days] while the matter is active, this may indicate:

• The client has forgotten (prompt needed)
• The client is experiencing cash flow difficulties (relationship signal; billing partner should call)
• The client is dissatisfied with the billing (billing dispute risk; proactively discuss)
