Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
This page is for service businesses, agencies, consultants, and freelancers who need to turn tracked work into a client-ready invoice. The job is practical: capture billable time, separate non-billable work, apply the right rate, add clear invoice details, and send a document the client can approve without a long email thread.
A time-based invoice should show who billed the work, what project or service the work belongs to, the billing period, the quantity of time, the rate, the subtotal, any tax line that applies, the total due, payment terms, and remittance details. The invoice is a request for payment. A receipt proves payment received, and a quote or estimate gives a pre-work price.
Start with complete time entries. Each entry needs a date, person, project or client, task or service description, billable status, and approved duration. For client billing, vague descriptions create approval friction. A line such as "Design QA, June 3, 2.5 hours at $95 per hour" gives the client more to verify than "miscellaneous project work."
After the time records are ready, group them in the way the client expects. Some clients approve by project phase, some by task, some by person, and some by date. The invoice should keep the math visible: quantity multiplied by rate, subtotal, discount when used, tax line when required, total due, issue date, due date, invoice number, seller details, buyer details, and payment instructions.
United States private-sector invoices do not follow one prescribed federal invoice form or a national VAT or GST invoice regime. For federal tax records, invoices act as supporting documents that help show income, expenses, and the amounts and sources of gross receipts. Sales and use tax treatment depends on state and local rules, nexus, product or service taxability, and where the sale is sourced.
A service invoice should avoid automatic tax assumptions. California generally taxes retail sales of tangible personal property and only some service or labor charges, while Texas defines 16 broad categories of taxable services. Remote sellers also need state-specific nexus checks. South Dakota's rule reviewed in Wayfair used more than $100,000 in sales or 200 separate transactions annually, but other states set their own thresholds.
A one-off invoice works when the job is small, the rate is simple, and the client accepts a summarized service line. It also works for a standalone project where you can verify every hour before sending. That setup breaks down when several people bill to the same client, some tasks are non-billable, rates vary by person, or unbilled time must stay visible across billing cycles.
Everhour fits the managed workflow: tracked billable time and expenses can feed invoices, while reports keep invoiced and uninvoiced amounts visible. That matters when client billing needs an approval trail, project-level reporting, and a handoff to accounting. A durable workflow prevents the same time from being billed twice and gives managers a record of what stayed non-billable.

Group approved time entries by the structure the client expects, then show the billing quantity, rate, description, and amount for each line. A monthly invoice can group work by project, task, person, or date. The right grouping is the one that lets the client verify the charge without asking for a rebuilt timesheet.
Use a unique invoice number, issue date, due date, seller and buyer details, billing period, line-item descriptions, quantities, rates, subtotal, tax line when applicable, total due, payment terms, and remittance details. Add project names or purchase order references when the client requires them. Missing references often slow approval even when the amount is correct.
Non-billable time usually stays out of the amount due. Some teams show non-billable work as a zero-charge line when the client expects visibility into support, project management, or warranty work. That choice should follow the contract and client reporting norm, because adding unpaid work can clarify value or create confusion.
A United States invoice needs sales tax only when the applicable state and local rules require tax for that sale. The United States has no national VAT or GST invoice regime and no single national sales tax rate. Service taxability varies by state and service type, so the seller must check the buyer location, nexus, and taxable category.
An invoice supports billing, but it is weaker than the underlying time records. A client can dispute a line item if the business cannot show dates, people, tasks, and approved hours behind the charge. Keep the time entries, approvals, project notes, and invoice copy together so the billing record explains both the amount and the work.
Everhour Reporting lets teams build reports with 45+ columns, filters, grouping, date ranges, and exports. A billing manager can review billable time, non-billable time, invoice status, revenue, costs, and project details before finalizing client invoices.
Everhour marks time as invoiced after it is included in an invoice, so the same entries do not appear again as uninvoiced work. That protects recurring billing cycles where several projects, people, and client invoices run at the same time.
Turn approved project time into reports before billing starts. Everhour gives teams invoice-ready visibility into billable work, uninvoiced amounts, and project profitability.
