12.3 Billable Time, Invoicing & Prohibited Billing Practices

Billable Time, Invoicing & Prohibited Billing Practices

Core Practice Standard: Content Area 1, Managing Private Investigation Business Operations, carries 15% of the examination, and Task T4 sits squarely inside it: maintain records of billable time and expenses to invoice clients. Candidates who prepare only the glamorous half of the syllabus lose these marks. The subject also has real teeth — billing misconduct is the single most common source of client complaints to BSIS, and it maps onto both disciplinary and criminal provisions.

Capture Time as It Happens

The only time record that survives scrutiny is the one created contemporaneously. Reconstruction from memory at month end produces round numbers, gaps, and overlaps — exactly the pattern a fee arbitrator or a cross-examiner looks for.

The surveillance log doubles as the time record. Each entry carries a clock time, a location, and an observation, so the log independently corroborates the hours billed. When the invoice says 06:15 to 14:45 and the log's first entry is 06:17 at a stated intersection and its last is 14:41, the billing is self-proving. When the log starts at 08:00 for the same billed day, it is not.

+---------------------------------------------------------------------------+
|  BILLABLE TIME RECORD — MINIMUM FIELDS                                    |
+---------------------------------------------------------------------------+
|  Matter number and client                                                 |
|  Date                                                                     |
|  Operative                                                                |
|  Start time / end time (portal-to-portal or on-site, per the contract)    |
|  Activity described in enough detail to justify the charge                |
|  Location or record source                                                |
|  Rate applied and the reason if it differs from the standard rate         |
|  Expenses incurred, with receipts attached                                |

Describe the activity. "Investigation — 6.0 hrs" is unbillable in substance because the client cannot evaluate it. "Stationary surveillance, 1400 block of Elm St, subject residence; subject vehicle departed 09:12, followed to jobsite; 6.0 hrs" is.

Constructing the Invoice

An invoice a client can approve without a phone call contains:

Three rate conventions to state in the engagement and repeat on the invoice: whether travel is portal-to-portal or on-site only; whether a surveillance minimum applies; and whether testimony and deposition time carries a separate rate and minimum. Ambiguity in any of the three produces most fee disputes.

Handling the Advance

An advance retainer is client money until it is earned. The practice that avoids trouble:

1. Record it as unearned on receipt and issue a receipt immediately, especially for cash.
2. Draw it down only against itemised, contemporaneously recorded entries.
3. Show the running balance on every invoice.
4. Request replenishment at the trigger stated in the engagement, before the balance is exhausted.
5. Refund the unearned balance promptly at termination with a final itemised accounting.

Retaining an unearned balance after the engagement ends is the fact pattern behind a large share of BSIS complaints, and it engages both the dishonesty grounds in BPC § 7561.1 and § 7561.1(g).

Prohibited and Fraudulent Billing (K11)

That last row is a genuine Private Investigator Act provision candidates rarely see coming: § 7539(i) contains not only the injured-person solicitation ban but also a flat prohibition on bounty-style compensation for violations found.

The Employee Side: Labor Code § 2802

Billing is only half the ledger. Labor Code § 2802(a) requires an employer to indemnify employees for all necessary expenditures or losses incurred in direct consequence of the discharge of their duties. For an investigative agency that means mileage or actual vehicle costs, mandated equipment, and business use of a personal mobile phone. An agency that bills the client for mileage and does not reimburse the operative has a wage claim waiting, and the operative's mileage log is the same document that supports the client charge — which is a good reason to keep exactly one of them.

When a Client Disputes an Invoice

1. Produce the underlying records — the log, the notes, the receipts. If they do not exist, the charge is indefensible; concede it.
2. Separate the components. Disputes usually attach to one or two entries; resolving those quickly preserves the relationship and the rest of the bill.
3. Correct genuine errors immediately by credit memo, dated and explained.
4. Do not withhold the completed report as leverage. Refusing to deliver a report for which compensation has been paid or tendered is the express language of BPC § 7561.1(g).
5. Escalate through the contract's dispute clause rather than to a lien on the client's file.

Case Example: The Reconstructed Month

Scenario: An operative works six surveillance days over three weeks and keeps handwritten logs. At month end the agency owner, unable to read some entries, prepares the invoice from memory: six days at 8.0 hours each, exactly 48.0 hours, plus 240 miles at the stated rate. The client requests the logs. Three logs show 6.5, 7.0, and 5.75 hours; two are illegible; one is missing.

The exposure. The 48.0-hour figure overstates the documented time by at least several hours, and the perfect uniformity of the entries is itself an indicator of reconstruction. If the owner knew the hours were not worked as billed, the invoice narrative is a knowingly false report under BPC § 7539(b) and theft by false pretences under Penal Code § 532, with the dishonesty grounds in BPC § 7561.1 available to the Bureau.

The right handling. Bill only the documented hours, disclose the two illegible and one missing logs, credit the difference, and fix the system — contemporaneous entry on a standard form, legible or digital, reconciled to the invoice before it issues. A short, honest invoice with a credit memo keeps the client. A tidy invoice built from memory loses the licence.
