Accepted Answer

Yes, completely free with no hidden costs. Download in Excel, PDF, or Word format as many times as needed. No account required, no email signup, no credit card, no catch. Just click download and start using it immediately for your consulting business.

Question 2

What should I include on a consulting invoice?

Accepted Answer

Every consulting invoice should include: your name or business name and credentials (MBA, CPA, etc.), contact information (address, phone, email, website), client name and company information, unique invoice number, invoice date and due date, engagement or project reference, detailed description of consulting services provided, dates of service or time period covered, hours worked and hourly rate (if hourly billing) or fixed fee (if project-based), any billable expenses with descriptions, subtotal before tax, applicable taxes (if required), total amount due, payment terms (Net 15, Net 30, etc.), accepted payment methods with instructions, and any relevant notes or terms.

Question 3

How should I price my consulting services?

Accepted Answer

Consultants typically use four pricing models: Hourly billing ($150-$500/hour depending on expertise) for ongoing work or unclear scope, project-based fees ($5,000-$100,000+) for defined deliverables with clear scope, monthly retainers ($2,000-$25,000/month) for ongoing access and advisory, or value-based pricing tied to outcomes delivered. Your pricing should reflect your experience, specialization, client type, and the value you deliver. Research market rates for your specific consulting niche and geography.

Question 4

Should I ask for a deposit from consulting clients?

Accepted Answer

Yes, especially for new clients or projects over $5,000. Request 25-50% upfront before starting work. Deposits are standard in consulting and serve multiple purposes: they ensure client commitment, protect your time investment, improve cash flow, and filter out non-serious inquiries. Most legitimate clients expect deposits. Invoice the deposit separately, then credit it against the final invoice.

Question 5

What are typical payment terms for consulting services?

Accepted Answer

Common consulting payment terms include: Net 30 (payment due within 30 days) for established corporate clients, Net 15 (due within 15 days) for smaller businesses or faster payment, Due Upon Receipt for small projects or new clients, and monthly in advance for retainer agreements. Always discuss and document payment terms before starting work. Include them in your engagement letter and on every invoice.

Question 6

Can I customize the consulting invoice template?

Accepted Answer

Absolutely. All templates are fully customizable. Add your company logo and brand colors, include your credentials and certifications, change fonts and styling, modify line items and descriptions, adjust tax fields for your jurisdiction, add custom payment terms, include engagement references, add disclaimers or terms of service - make it completely yours. Excel and Word formats are especially easy to customize.

Question 7

Do I need to charge sales tax on consulting services?

Accepted Answer

It depends on your location and the type of consulting services provided. In the United States, most states do not charge sales tax on professional consulting services (strategy, advisory, management consulting), but some states do. In the European Union, VAT generally applies to consulting services. In Canada, GST/HST typically applies. Rules vary significantly by jurisdiction and service type. Consult with an accountant or your local tax authority to ensure compliance.

Question 8

How do I bill for retainer consulting agreements?

Accepted Answer

For retainer clients, send invoices monthly on the same date each month (typically at the beginning of the billing period). Your retainer invoice should show: the monthly retainer fee, hours or services included in retainer, summary of work completed that month (to demonstrate value), any additional hours beyond retainer with hourly rate, billable expenses if applicable, and total amount due. Be clear about what is included and what costs extra.

Question 9

Should I bill consulting time in hourly increments?

Accepted Answer

Most consultants bill in 15-minute (0.25 hour) increments, though some bill in 6-minute (0.1 hour) increments like attorneys. Never bill in increments smaller than 6 minutes - it looks petty and is hard to track accurately. Round appropriately: a 10-minute call becomes 0.25 hours (15 minutes). Use time-tracking software to capture time accurately throughout the day rather than trying to reconstruct it later.

Question 10

What payment methods should I accept as a consultant?

Accepted Answer

At minimum, accept bank transfers (ACH, wire) or checks. However, offering digital payment options speeds payment significantly. Consider: PayPal (widely used, 2.9% + $0.30 fee), Stripe (professional, similar fees), credit cards (highest fees but fastest payment), Zelle or Venmo (for small amounts), TransferWise/Wise (best for international clients). The more payment options you offer, the faster you get paid. Many consultants absorb payment processing fees as cost of doing business.

Question 11

How do I follow up on unpaid consulting invoices?

Accepted Answer

Use a gentle escalation approach: Send a friendly reminder 3-5 days before due date, follow up 2-3 days after due date with polite email ("Following up on invoice #123 which was due on the 15th"), make a phone call 7-10 days overdue, send a firmer email after 2 weeks, consider pausing work after 30 days unpaid. Most late payments from corporate clients are process issues, not refusals to pay. Stay professional but persistent.

Question 12

How often should I invoice consulting clients?

Accepted Answer

It depends on your agreement. For hourly work, invoice weekly or bi-weekly to keep amounts manageable and cash flow steady. For project work, invoice at predetermined milestones (like 50% on approval, 50% on delivery). For retainer clients, invoice monthly on the same date each month. More frequent invoicing generally results in faster, more predictable cash flow.

Question 13

Should I include late fees on consulting invoices?

Accepted Answer

Yes, include late fee terms (typically 1.5-2% per month on overdue balances) on invoices. This encourages timely payment even if rarely enforced. However, be cautious about actually charging late fees to good clients - a payment reminder is often more effective than fees. For chronic late payers, enforce the fees or require payment in advance. Always include late fee terms before work begins, not retroactively.

Question 14

How should I bill for consulting expenses?

Accepted Answer

Always discuss expense billing before starting work. Bill expenses separately from consulting fees with brief descriptions and dates. Common billable expenses include travel (airfare, mileage at IRS rate), accommodation and meals (often with per diem limits), research databases or reports, specialized software, third-party services, and materials. Most consultants bill expenses at cost without markup. Include receipts for large expenses.

Question 15

What credentials should I include on consulting invoices?

Accepted Answer

Include relevant professional credentials after your name: degrees (MBA, PhD, MA), certifications (PMP, CPA, CFP, CFA, SHRM-SCP), professional designations, and industry-specific certifications. This reinforces your expertise and justify your consulting rates. For corporate clients especially, credentials validate their investment and make it easier to justify internally.

Question 16

Do I need a contract if I have an invoice?

Accepted Answer

Yes, for anything beyond very small one-off consultations. Contracts (engagement letters) and invoices serve different purposes. Contracts outline scope of work, deliverables, timelines, payment terms, intellectual property rights, confidentiality, liability limitations. Invoices request payment for work performed. Always use both for consulting engagements. Reference the contract or engagement letter number on invoices.

Question 17

Should I send consulting invoices in PDF, Excel, or Word format?

Accepted Answer

Send clients PDF versions - they look polished and cannot be edited. Use Excel internally to build invoices because formulas automatically calculate hours, rates, expenses, taxes, and totals. Word works if you prefer text editing. Many consultants build in Excel, then export to PDF before sending. Never send editable Excel or Word files to clients - always send PDF for professionalism.

Question 18

How do I handle scope creep on consulting projects?

Accepted Answer

Prevent scope creep with clear engagement letters defining deliverables. When clients request work beyond scope, stop and discuss before proceeding. Provide written quotes for additional work and get approval. Invoice additional work separately or as a change order. Never assume clients will pay for out-of-scope work - get approval first. Set boundaries professionally.

Question 19

Should I invoice in my currency or the client's currency?

Accepted Answer

For domestic clients, invoice in your local currency. For international clients, you can invoice in either currency. Invoicing in their currency makes payment easier for them, while your currency protects you from exchange rate fluctuations. Many consultants invoice international clients in USD as it is widely accepted. Clarify currency expectations before work begins.

Question 20

How do I create an invoice numbering system?

Accepted Answer

Keep it simple and consistent. Use formats like: Sequential (001, 002, 003), year-based (2024-001, 2024-002), or client-based (CLIENT-001). Never reuse numbers or skip numbers. This helps with bookkeeping and looks professional. Some consultants start at a higher number (like 1001) to appear more established rather than starting at 001.

Question 21

Can I send invoices via email or should I mail them?

Accepted Answer

Email is preferred and faster. Send invoices as PDF attachments (not editable formats). Use clear subject lines like "Invoice #123 from [Your Name] - Due March 15". Include a brief message in the email body, then attach the PDF. Email creates automatic paper trails and gets you paid faster. Mail paper invoices only if clients specifically require them.

Question 22

Should I offer early payment discounts?

Accepted Answer

If cash flow is important, yes. Offer 2-5% discount for payment within 5-7 days. Note it clearly: "2% discount if paid within 7 days" with both amounts shown. Many clients appreciate this option, and faster payment is often worth more than the small discount. This works especially well with corporate clients who have long payment processes.

Question 23

How do I invoice for discovery or diagnostic work?

Accepted Answer

For initial discovery, assessment, or diagnostic work, either charge your full hourly rate, offer a discounted "engagement fee" to win the project, or propose a fixed fee for the discovery phase. Be clear that discovery is a separate billable phase. Invoice immediately upon completion. The discovery phase should demonstrate value and lead to the larger consulting engagement.

Question 24

What should I do with paid consulting invoices?

Accepted Answer

Mark the invoice as paid in your records, note the payment date and method, send a payment receipt to client as confirmation, save invoice and receipt for at least 7 years for tax purposes, update your accounting software, and file digitally in organized folders. Good records make taxes easier and help resolve any questions that arise later.

Question 25

Should I include deliverables timeline on invoices?

Accepted Answer

For project-based work, yes - briefly reference what was delivered and when. For example, "Strategic plan delivered March 15" or "Market research report completed and presented March 20". This connects the invoice to concrete deliverables and reinforces value. For hourly work, include dates of service for each line item.

Question 26

How do I bill for phone and email consulting?

Accepted Answer

Bill phone consultations and substantive email advisory time just like in-person time. Track phone calls to the nearest 15 minutes. For email, bill only substantial email work (detailed responses, complex analysis) not quick questions. Be clear about what communication is included versus billable. Some retainer agreements include reasonable email/phone access.

Question 27

Can I charge interest on late consulting payments?

Accepted Answer

Yes, in most jurisdictions, but you must include interest terms on the invoice before work begins. Common rates are 1.5% per month (18% annually). Check local laws as some limit interest rates. Including terms often encourages payment even if never enforced. For valued clients, use reminders instead of charging interest.

Question 28

Should I add a thank you note to consulting invoices?

Accepted Answer

Yes, a brief professional thank you strengthens relationships. Use phrases like "Thank you for the opportunity to work with you" or "I appreciate your business." For project completion, add "It was a pleasure supporting your strategic initiative." Keep it professional, not overly casual. Personal touches encourage repeat business.

Question 29

How do I handle partial payments from clients?

Accepted Answer

If a client pays less than invoiced, contact them immediately to clarify. Issue a receipt for the amount paid and a new invoice for the remaining balance with the original invoice referenced. Document the partial payment in your records. If partial payments become a pattern, address it directly and consider requiring payment in advance.
