Common IT Consultant Invoicing Mistakes

Real work gets messy, but simple fixes keep invoices clear and cut pushback.

Mistake

How to fix it

Vague work descriptions cause confusion and slow approvals.

Write short, outcome-based descriptions that say what changed and why it mattered, and tie each line to a ticket or deliverable.

Combining roles or rates into one line hides pricing and leads to disputes.

List separate lines for each role or rate and show hours per line to make review easy.

Invoice a deposit before kickoff and state how you will apply it to the first milestone or final bill.

Add the service dates and include SOW, PO, and ticket numbers so AP can match records fast.

Applying incorrect tax treatment creates compliance problems and rework.

State tax clearly, itemize taxable and non-taxable items, and check local rules.

Leaving out payment terms and late fees invites slow pay.

Include the due date, accepted methods, and late fee policy so expectations are clear and enforced.

How should I bill for discovery and assessment time?

Bill it as its own service with hourly detail. Example: “Network Assessment: 3 hrs @ $160/hr: $480.” If you credit it later, add “Project Credit: –$480.”

What goes on an invoice for a fixed-price project vs hourly?

For fixed price, list the scope and milestone. Example: “M365 Migration—Phase 1 (fixed): $4,500.” For hourly, list time and rate. Example: “Remote Support: 2.5 hrs @ $150/hr: $375.”

How do I show software licenses and other pass-through costs?

Create a “Licenses & Subscriptions” section with unit counts. Example: “Microsoft 365 Business Standard: 12 seats @ $12.50: $150/mo.” Add “Procurement Admin Fee: 10%: $15.”

Can I charge for travel, onsite minimums, or after-hours emergency work?

Yes. Make them separate lines. Example: “Onsite Minimum: 1 hr @ $175: $175,” “Travel: 18 mi @ $0.67: $12.06,” “Emergency After-Hours Surcharge: 25%: $93.75.”

How should retainers or prepaid support blocks appear?

Show the deposit, then deduct usage. Example: “Retainer Received: $3,000,” then “Block Drawdown—Help Desk: 4 hrs @ $150: –$600,” with “Retainer Balance: $2,400.” Note refill rules in terms.

What’s the clean way to handle change orders mid-sprint?

Add a new scoped line and reference the change order ID. Example: “CO-004: Additional VLANs: 6 hrs @ $165: $990.” Keep original sprint items unchanged.

Do I charge sales tax on labor, hardware, or software in the U.S.?

Rules vary—check local rules. Many states tax hardware and some software, but not pure labor. Example: “Firewall Appliance: $1,200 + Sales Tax 8.25%: $99,” “Configuration Labor: non-taxable.”

How do I show milestone billing and partial payments on a long project?

Bill per milestone with percent complete. Example: “Data Center Refresh—Milestone 2 (40%): $8,000,” then show prior payments: “Less Payment #1: –$5,000.” Display “Balance Due: $3,000.”
