Use this page to turn managed client work into an invoice that a finance contact can review without chasing context. A manager's invoice commonly ties each charge to a project, contract, authorization, milestone, task group, or approved resource plan. The goal is a finished billing document with enough detail to support payment, internal review, and later recordkeeping.
A project invoice should identify the invoice date and number, the client, the contract or authorization, line-item descriptions, quantities or hours, unit measures, unit prices, extended prices, payment terms, and remit-to details. Add a defect-contact person when the contract requires one, especially for government or enterprise clients that route invoice questions through a specific billing office.
Fixed-price billing works when the agreement sets one amount for a defined scope. The invoice can show the milestone, deliverable, or phase, then bill the agreed price without adjusting the amount based only on actual cost experience. This format fits work such as a completed implementation phase, a monthly management retainer, or a documented project deliverable.
Time-and-materials billing needs more supporting detail. The invoice is based on labor hours multiplied by specified fixed hourly rates, plus actual material costs. Labor-hour billing removes the materials portion, so the invoice centers on labor categories, hours, and fixed rates. Cost-reimbursement work requires support for allowable incurred costs, such as direct labor, direct travel, other direct costs, and properly allocable indirect costs, subject to the contract.
United States invoices do not follow a national VAT or GST invoice regime, and ordinary private-sector businesses do not use one prescribed federal invoice form. Sales and use tax belongs to state and local rules, with taxability, nexus, product or service type, and customer location driving the answer. A manager invoice should show the correct sales-tax treatment for the transaction instead of using a generic national rate.
Payment terms come from the contract, client policy, and applicable law. Federal contract invoices are a clear national exception: a proper invoice under FAR rules includes specific fields, and the standard payment due date is generally the later of 30 days after the billing office receives a proper invoice or 30 days after government acceptance. Private-sector late fees follow the contract and jurisdiction.
A one-off invoice works for a simple milestone, a single client approval, or a clean fixed-price charge. It also works when the manager already has the approved hours, rates, expenses, tax treatment, and payment terms in front of them. The risk grows when the same team bills several projects, labor categories, rate schedules, or pass-through expenses every month.
A managed workflow becomes necessary when tracked work needs to feed billing without re-keying. Everhour separates internal cost rates from client-facing billable rates, supports per-person defaults and per-project overrides, preserves dated rate history, and prices billable work by project, member, or task. That structure helps managers keep labor cost, client revenue, and invoice pricing aligned.

A manager invoice should include the client name, invoice date and number, project or contract reference, item descriptions, quantities or hours, unit measures, unit prices, extended prices, payment terms, remit-to details, and a contact for invoice defects when the contract requires one. For contract-based work, the project or authorization reference matters because it connects the charge to the approved scope.
A time-and-materials invoice should show direct labor hours, the fixed hourly rate for each labor category or person, and actual material or pass-through costs. The clearest format separates labor from reimbursable costs, then adds enough description to show the client which project tasks or resources produced the charge.
A U.S. manager invoice does not use a national VAT or GST invoice regime. Sales and use tax is imposed and administered by states and local jurisdictions. The right treatment depends on state and local rules, nexus, the product or service sold, and where the customer receives the goods or services.
A fixed-price invoice does not need hours to calculate the price when the agreement bills an agreed amount for defined work. Managers often add milestone names, deliverable descriptions, or period covered to make the charge easier to approve. Adding hours for context is a business choice unless the contract requires them.
Missing contract references delay approval because the reviewer cannot match the invoice to the purchase order, statement of work, milestone, or authorized budget. Rate mismatches create the same problem in time-and-materials billing. The invoice should use the same labor categories, rates, and terms that appear in the client agreement.
Everhour separates cost and billable rates, then lets managers use default per-person rates or per-project overrides. Dated rate changes preserve older calculations, while project, member, and custom task rates keep invoice pricing aligned with the client's billing model.
Everhour Billing & Invoicing converts uninvoiced billable time and expenses into client invoices. Managers can preview the breakdown, group line items by project, task, person, or date, and export invoice drafts to QuickBooks Online, Xero, or FreshBooks.
Track approved work at the right billable rate, then turn it into invoices with fewer manual edits. Everhour gives managers cleaner project billing and better revenue visibility.
