Client billing time records that hold up

Start with invoice-ready time

You came here to turn client work into billable records that can support an invoice. Each entry needs enough detail for a customer to understand the charge without reading your internal project notes. Track the client, project or matter, service date, service description, hours or quantity, rate or price, and whether the time is billable or non-billable.

For U.S. users, rate and invoice fields normally use U.S. dollars. A clean entry might read: client strategy call, ACME website redesign, March 5, 2026, 1.25 hours, $150 per hour. That gives the invoice a description, quantity, price, and amount without rebuilding the work history from memory.

Separate billing from payroll records

Client billing time and employee wage records serve different purposes. Billable time is work time charged to a client under the agreement. Payroll records for covered nonexempt employees under the FLSA must include hours worked each workday and total hours worked each workweek, regardless of whether the client pays for those hours.

A covered nonexempt employee can spend 44 hours working in one fixed 168-hour workweek while only 37 hours are billable to clients. Federal overtime for covered nonexempt employees applies after 40 hours in a workweek at not less than one and one-half times the regular rate. Do not average hours across workweeks to smooth either payroll review or client billing.

Build the invoice trail

A time-based invoice usually needs a unique invoice number, seller and customer details, service dates, invoice date, clear charge descriptions, amounts, tax when applicable, total owed, due date, and payment method. Time entries supply the evidence behind those lines. Vague notes such as "admin" or "miscellaneous support" create follow-up questions and slow approval.

Client-billing records also support business recordkeeping. The IRS lists invoices as documents that support gross receipts and entries in books and tax returns. Electronic records should stay legible, complete, accurate, retrievable, and reproducible. For legal services, invoice descriptions also need care because ABA Model Rule 1.6 protects information relating to client representation.

Move beyond one-off totals

A one-off weekly total works when you need a quick estimate for a small job or a simple invoice from your own notes. It stops working when several people touch the account, the client asks for detail, a manager must approve hours, or payroll and billing need different views of the same work.

A managed workflow keeps client, project, task, billable status, rate, and approval status attached to each entry. Everhour Timesheets collect weekly project hours and working hours, then let users submit time for review while managers approve, reject, partially approve, or lock entries before billing review. That approval trail reduces invoice rework.

Frequently Asked Questions

What is the best way to record billable client time?

Record time by client, project or matter, date, service description, billable status, hours or quantity, and rate. Keep notes specific enough to justify the charge, but avoid internal shorthand that the client will not recognize. The strongest record lets you create the invoice line without rewriting the work after the fact.

How detailed should client billing notes be?

Client billing notes should identify the service performed and the business purpose behind it. A useful note says "drafted Q2 ad budget revisions" instead of "worked on file." Legal billing needs extra caution because ABA Model Rule 1.6 requires lawyers to protect information relating to client representation unless disclosure is authorized.

Should approved time entries always become invoice lines?

Approved time entries should become invoice lines only when the agreement makes them client-chargeable. Internal review, training, rework outside the client scope, or account management can stay non-billable while still remaining in the time record. Keep the non-billable label clear so utilization, payroll review, and invoice totals do not conflict.

Can client billing records be kept electronically?

Electronic client billing records can be kept electronically when they remain legible, complete, accurate, retrievable, and reproducible. U.S. tax recordkeeping expects electronic business records to preserve and reproduce complete records accessible to the IRS. Exportable invoices, time reports, and supporting entries make later review easier.

How long should billing time records be kept?

Billing time records should follow the retention rules that apply to the business, tax, contract, and worker records involved. For FLSA-covered employers, payroll records must be preserved for at least three years, and basic time and earnings records such as time cards or sheets must be preserved for at least two years.

How does Everhour help approve client billing time?

Everhour Timesheets collect weekly project hours and working hours by person, so teams can submit time before billing review. Managers can approve, reject, partially approve, and lock submitted entries, which keeps corrected time separate from unreviewed drafts before invoices are prepared.

How does Everhour connect tracked time to client invoices?

Everhour supports invoice generation from tracked time, so approved project hours can move into billing without retyping entries. Teams can keep client, project, task, and billable details in the time record, then use that information when preparing invoice lines.

Turn approved time into billing

Track client work with submitted timesheets, manager approvals, and locked billing records. Everhour keeps reviewed project hours ready for invoice preparation and client billing.
