Use this page to prepare an invoice for residential or commercial interior design work, such as space planning, selections, documentation, coordination, project management, or post-occupancy follow-up. The finished invoice should show the client who is billing them, which project the charge belongs to, the billing period, the payment terms, and the exact services, products, or reimbursable costs included.
Interior designers commonly bill through flat fees, hourly rates, cost-plus purchasing, retainers, or hybrid structures. A clear invoice mirrors the agreement. A remodel may include hourly design time, a procurement commission, reimbursed sample costs, and a separate change-order line. A fixed-fee room design may instead show a phase payment tied to concept development or design documentation.
A complete interior design invoice usually includes your business name, client name, project address or project name, invoice number, invoice date, due date, payment terms, service lines, quantities or hours, rates, discounts, taxes where applicable, and the total due. Private-sector United States invoices do not follow one prescribed federal invoice format, but invoices serve as supporting documents for income and expense records.
Line items should be specific enough for the client to recognize the work. For example: "Design development and selections, primary suite, 7.5 hours at $175 per hour" is clearer than "Design services." For purchasing work, separate the item cost, markup or commission, delivery charge, and reimbursable expense when the client agreement treats those items differently.
Interior design billing breaks down when the invoice ignores the pricing model. A flat-fee invoice should tie charges to the agreed phase, deliverable, or milestone. An hourly invoice should list the period, task category, hours, and rate. A retainer invoice should show the upfront amount and explain whether later work draws against it or bills separately under the contract.
Purchasing and procurement need extra care. Some interior designers charge a product commission or markup, commonly reported in the 10% to 35% range for furniture and home-item purchasing. For furniture, fixtures, and equipment work with a clear scope, a flat fee can also be paired with a percentage component. State the model plainly so the client can match the invoice to the proposal.
A one-off invoice is enough for a small consultation, a single styling session, or a simple fixed-fee room package. A managed workflow becomes necessary when multiple team members track hours, procurement expenses change during the project, non-billable revisions need to stay out of client totals, or the client expects invoice detail by phase, task, person, or date.
Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates invoice amounts from rates, excludes non-billable tasks, and supports client settings such as taxes, discounts, and payment terms. Invoices can be exported to QuickBooks Online, Xero, or FreshBooks, with invoice status, number, issue date, and amount syncing back to Everhour.

An interior designer invoice should include business and client details, project name or address, invoice number, invoice date, due date, payment terms, line items, rates, quantities or hours, taxes where applicable, and total due. Strong line items separate design labor, procurement activity, reimbursable expenses, product commissions, retainers, and scope-change charges.
Design phases should appear as separate lines when the contract bills by milestone or phase. Common phase labels include discovery and programming, concept development, design development and selections, documentation, coordination, project management, and post-occupancy evaluation. Each line should show the billed phase, covered deliverable, billing period, and amount due.
Procurement purchases and design fees should be separated when the client agreement prices them differently. A clear invoice can show design hours, product costs, commission or markup, freight, delivery, installation coordination, and reimbursable expenses as distinct lines. This structure reduces disputes because the client sees which charges pay for services and which charges pass through purchase activity.
A United States interior design invoice does not need VAT or GST because the United States does not use a national VAT or GST invoice regime. Sales and use tax obligations come from state and local rules. Service taxability varies by state and service type, and sellers that make taxable sales may need state-level sales-tax registration.
Client pushback often starts when the invoice combines design labor, product costs, revisions, and procurement charges into one vague total. Interior design projects often change as selections, delivery timelines, and client decisions change. Separate original scope work from approved change orders, and label reimbursable purchasing activity distinctly from professional design fees.
Everhour Billing & Invoicing lets teams select uninvoiced billable time and expenses, preview the breakdown, and generate an invoice from rates, time, and billable expenses while excluding non-billable work. Invoice lines can be grouped by project, task, person, date, or another available breakdown.
Track billable design time, expenses, and client terms in Everhour, then generate invoices from approved project records instead of rebuilding billing detail by hand.
