Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
You need one invoice that can bill several projects without mixing scopes, rates, taxes, or payment terms. That usually means separating each project into its own group of line items, then showing the description, quantity, rate, subtotal, tax line, total, due date, and remit-to details clearly enough for approval.
A project-based invoice is still a business record, not a special federal form for ordinary private-sector United States billing. The IRS treats invoices as supporting documents that help show business transactions, gross receipts, and expenses. Client contracts, state and local tax rules, and internal approval policies decide most of the practical format.
A clean multi-project invoice starts with seller and buyer details, a sequential invoice number, issue date, due date, payment terms, and payment instructions. Each project should then have its own label, such as "Website redesign" or "Q2 support," followed by line items that show the work performed, quantity, rate, and extended price.
Line items should match the way the client approves work. A fixed-fee project can use milestone lines, while hourly work should show hours and rates by project, task, person, or date when that level of detail supports approval. The invoice total should roll up from those project sections, with discounts and taxes shown separately from the underlying work.
The United States does not use a national VAT or GST invoice regime. Sales and use tax obligations come from state and local jurisdictions, and taxability depends on nexus, the product or service sold, and where the sale is sourced. A single flat tax line applied across every project creates problems when one project includes taxable goods and another covers nontaxable services.
Service taxability also varies by state and service type. California generally taxes retail sales of tangible personal property and only some service or labor charges, while Texas identifies 16 broad categories of taxable services. If a client receives work in different jurisdictions, keep the project descriptions and tax treatment detailed enough to support the rate used.
A free one-off invoice works for a small client, a single billing period, or a project bundle that does not need approval history. It gives you a finished document, usually a PDF, and keeps formatting from slowing down the billing step. It does not create a durable record of uninvoiced work across projects.
A managed workflow fits better when tracked billable time, project costs, and expenses need to feed the invoice. Everhour supports project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and reports for billable time, non-billable time, billable amount, and cost, so project totals stay ready for billing review.

Yes. One invoice can cover several projects when the client accepts consolidated billing and the invoice separates each project clearly. Use project headings, line items, rates, subtotals, and tax treatment that match the work. Separate project sections help the client approve charges without guessing which budget, purchase order, or department should absorb the cost.
A project invoice should include seller and buyer details, a sequential invoice number, issue date, due date, payment terms, remit-to details, and line items grouped by project. Each line should show a description, quantity, rate, and extended price. Add project subtotals before the final subtotal, tax line, discounts, and amount due.
Taxes should be shown in the way that makes the tax treatment understandable and auditable. A single tax line works when every project has the same tax treatment. Project-level tax lines work better when services, goods, jurisdictions, or client locations differ. The United States has state and local sales and use tax, not a national VAT or GST invoice regime.
Yes. Hourly and fixed-fee projects can appear on the same invoice if each line identifies the pricing basis. Hourly work should show hours and rates or an approved summary. Fixed-fee work should show the milestone, deliverable, or project phase being billed. Mixing pricing models without labels invites client questions.
The most common mistake is collapsing all work into one vague line item. Client reviewers need to connect each charge to a project, budget, contract, or approval path. Missing project names, unclear dates, reused invoice numbers, and tax lines that ignore state and local rules all slow payment.
Everhour lets admins set project billing status, mark specific tasks as non-billable, apply custom task rates, and use member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so invoice review starts from categorized project data instead of a manual time summary.
Everhour Billing & Invoicing turns uninvoiced billable time and expenses into client invoices. Invoice data can be grouped by project, task, person, date, or another available breakdown, then exported to QuickBooks Online, Xero, or FreshBooks as a draft for accounting review.
Track billable and non-billable project work before billing starts. Everhour keeps rates, task status, and invoice-ready reports connected for cleaner client invoicing.
