Create professional consulting invoices with project fees, retainer billing, and expense reimbursement. Free invoice maker for consultants. No signup.
Consulting invoices have unique requirements — project phases, retainer arrangements, expense reimbursements, and multiple deliverables across billing periods. Our generator handles all consulting billing structures with professional formatting that signals credibility to corporate clients and gets invoices approved through accounts payable faster.
Professional consulting invoices include: project or engagement name, SOW reference number, billing period, itemized deliverables or hours, expense line items with receipts notation, payment terms Net 30 standard for B2B consulting, wire transfer and ACH details for large invoices, and late payment terms.
Net 30 is standard for B2B consulting meaning 30 days to pay. For new clients consider Net 15 for faster payment. For long-term corporate clients Net 30 is expected. Add a 1.5% monthly late fee to incentivize on-time payment — rarely invoked but effective. Require upfront payment for new consulting relationships with no track record.
Consulting invoice essentials: your company name and contact info, invoice number and date, client name and billing address, engagement description, itemized fees as hours times rate or fixed project fees, expense reimbursements with dates, subtotal, tax if applicable, total due, payment terms, and payment instructions.
