Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
A billable-hours calculation answers one practical question: how much approved client work should appear on an invoice. On Safari, the math is the same as on any modern browser; the useful workflow detail is keeping the source timesheet, engagement letter, or rate schedule open in another tab while you check hours, rates, exclusions, and taxes.
The inputs are straightforward: billable hours, hourly rate, write-downs, non-billable exclusions, and any jurisdiction-specific tax that applies to the service. U.S. billable-hour totals are normally stated in USD. The United States has no federal VAT/GST or national sales-tax rate for billed professional time, so state and local rules control any tax line.
Only approved billable work belongs in the invoice amount. Internal meetings, admin time, sales calls, training, or project cleanup stay outside the billable subtotal unless the client agreement says those items are chargeable. For U.S. lawyers, the basis or rate of fees and expenses must be communicated in writing for new client-lawyer relationships under ABA Model Rule 1.5, subject to its limited low-cost exception.
The common mistake is multiplying every tracked hour by the client rate. That inflates the invoice and hides utilization problems. Keep three buckets separate: billable hours for the invoice, non-billable hours for management review, and written-off billable hours for revenue leakage. The invoice uses the first bucket, while the other two explain why total work time and billed value differ.
Multiply each approved billable category by its agreed rate, then add the line amounts. For example, a product advisory project includes 20 approved strategy hours at $150 per hour and 18 approved research hours at $100 per hour. The pre-tax billable subtotal is $4,800.
Tax is a separate input, not a federal default. If the service is taxable in Texas and only the 6.25% state sales and use tax rate applies, the tax is $300 and the invoice total is $5,100. If local Texas jurisdictions apply, the combined rate can reach 8.25%. If the service is not taxable in the relevant state or locality, do not add a tax line.
A one-off calculator is enough when you need a quick invoice check, a client estimate, or a second look before sending a small bill. It works best when the hours are already approved, the rates are written down, and the tax treatment is known for the client's jurisdiction.
A managed workflow is better when multiple people record time, rates differ by project or person, or invoices must match project tasks. Everhour connects with major project management and accounting tools, embeds tracking controls in supported workflows, and syncs project and task metadata so approved time can move into billing without rebuilding the invoice from scattered entries.

You need approved billable hours, the billing rate for each work category or person, any write-downs, and the jurisdiction-specific tax input when the service is taxable. Keep non-billable work in the record, but exclude it from the invoice subtotal unless the client agreement makes it chargeable.
No. Safari does not change the formula, tax treatment, or invoice result. The practical Safari workflow is browser-based: keep the source timesheet, rate agreement, and calculator open in separate tabs, then use print or PDF export after reviewing the subtotal, tax line, and final total.
Non-billable work should not increase the invoice amount. It should stay visible for internal review because it affects project profitability, staffing, and future estimates. The billable-hours total uses approved client-chargeable time only, while non-billable time explains the gap between total effort and client revenue.
No. The United States has no federal VAT/GST or national sales-tax rate for billed professional time. Sales tax and similar treatment are state and local matters, and different jurisdictions tax different services. Use the rate that applies to the service, location, and client situation.
Everhour integrates with major project management and accounting tools, adds tracking controls inside supported workflows, and syncs project and task metadata into one reporting layer. That keeps billable time connected to the same projects, tasks, and clients used for delivery.
Everhour lets admins set project billing status, mark specific tasks as non-billable, and report billable time, non-billable time, billable amount, and cost. That separation keeps client invoice totals distinct from internal effort and profitability analysis.
Use a calculator for quick checks; use Everhour when approved hours need to stay connected to projects, rates, accounting handoff, and repeatable client billing.
