When to use this template
Use this template for consulting and advisory work — monthly retainers, one-off strategy sessions, or milestone billing. It works equally well for solo consultants and small advisory firms.
Fields to include
- Consultant and client details
- Billing period or engagement reference
- Line items per service or session
- Retainer or hourly rate
- Tax where applicable
Sample line items
- Strategy session — 90 minutes1.5 × $150.00 = $225.00
- Monthly retainer — advisory support1 × $1200.00 = $1200.00
- Follow-up report and recommendations1 × $300.00 = $300.00
Practical tips
- Reference the engagement or purchase order number if the client uses one.
- For retainers, state the period covered on the invoice.
- Bill at the start of a retainer period, not the end.
Frequently asked questions
How do consultants bill for retainers?
Most bill a fixed monthly amount at the start of the month, using the same line items each period. You can reuse a saved invoice in Invoala to avoid re-creating it.
Should I charge for phone calls and emails?
Decide on a policy and state it in your agreement. Many consultants include them in a retainer, while hourly consultants track and bill them as time.
Do consultants need to charge tax?
That depends on your jurisdiction, registration status, and the client. Confirm your obligations locally rather than assuming.
