Create your consulting invoiceWhat to include on a consultant's invoice
Corporate clients expect detailed, structured invoices. Each type of work and expense should be a separate line item.
Consulting fees
List your hourly rate, day rate, or a fixed project fee. Include the number of hours or days clearly so the client can verify the total.
Retainer fees
Monthly retainers should be invoiced in advance. Specify what's included — number of hours, availability, and types of advisory work covered.
Workshop & training fees
Workshops, training sessions, and presentations are often priced as separate day-rate line items distinct from your regular consulting rate.
Expense reimbursements
Travel, accommodation, conference fees, and research costs should be listed at cost price with receipts available on request. Never embed expenses in your rate.
Report & deliverable fees
Written reports, audits, strategy documents, and other deliverables are often priced separately from advisory time. Make this distinction explicit.
Subcontractor costs
If you've engaged specialists on behalf of the client, pass those costs through as a separate line item at cost or with an agreed mark-up.
Why consultants need professional invoicing
Corporate accounts payable departments have strict requirements. A professional, correctly formatted invoice is processed faster — and gets you paid faster.
Corporate-ready format
Include PO numbers, legal entity names, and structured line items that corporate AP teams can process without back-and-forth.
Separate fees from expenses
Clients need to see your advisory fee and expense reimbursements as distinct items. Mixing them together triggers approval delays.
Track multiple clients
Most consultants juggle 3-5 active clients at any time. Useminty shows you outstanding invoices across all clients in one dashboard.
Frequently asked questions
What should a consulting invoice include?
A consulting invoice should include your business name and address, the client's legal name and purchase order number if applicable, a unique invoice number, invoice and due dates, an itemised list of services (hours, day rates, or milestones), expense reimbursements, VAT if applicable, and your bank details.
How do consultants charge for their time?
Consultants typically use one of three models: hourly rate (common for advisory and ad-hoc work), day rate (standard for on-site or project work), or a fixed project fee (for well-defined engagements like audits or strategy documents). Retainers are common for ongoing advisory relationships.
Should consultants invoice with a purchase order number?
For corporate clients, yes — always. Large companies require a PO number to process invoices through their accounts payable system. Without it, your invoice can sit in a queue for weeks. Ask for the PO number before you start work and include it prominently on the invoice.
How do consultants handle expense reimbursements?
List all expenses as separate line items at cost price — travel, accommodation, conference registrations, research subscriptions, etc. Keep receipts and note that documentation is available on request. Never embed expenses in your consulting rate, as it makes the invoice harder for the client to approve.
What payment terms do consultants typically use?
Net 30 is standard for large corporate clients, who often have fixed payment cycles. For smaller businesses, Net 14 is common. For new clients or large projects, request 30–50% upfront. Retainers are typically invoiced monthly in advance.
Do independent consultants need to charge VAT?
If your annual turnover exceeds the VAT threshold in your country, yes. For cross-border B2B consulting within the EU, the reverse charge mechanism usually applies — you don't charge VAT on invoices to VAT-registered clients in other EU countries, but you must note this on the invoice.
