Frequently Asked Questions
How should a consultant structure their invoice?
Clearly separate time-based fees (daily or hourly rates) from fixed deliverables. Reference the original engagement letter or proposal, and include a summary of work completed during the billing period.
Should I invoice for expenses separately?
It depends on your contract. Many consultants include expenses as separate line items on the same invoice, attaching receipts. Others bill expenses monthly. Whichever approach you use, agree it upfront with the client.
What are the IR35 implications for consultants?
If you work through a limited company, IR35 rules determine whether HMRC treats you as an employee for tax purposes. Medium and large clients must assess your IR35 status. Keep evidence of genuine self-employment such as control over work, substitution rights, and multiple clients.
What payment terms are standard for consulting?
Net 30 days is most common in the UK. For longer engagements, monthly invoicing with 14-30 day terms is standard. You can charge statutory late payment interest (8% + Bank of England base rate) on overdue invoices.
