Frequently Asked Questions
What's the difference between an invoice and a quote for consultants?
A quote is a pre-engagement document showing estimated costs, while an invoice is a post-service bill requesting payment for completed work. Consultants often provide quotes during sales and invoices after delivery.
Should consultants include terms and conditions on invoices?
Yes, basic payment terms should be on every invoice. However, detailed terms and conditions are better placed in your master service agreement rather than cluttering the invoice.
How often should consultants send invoices?
This depends on your agreement with clients. Common frequencies include: monthly for retainers, milestone-based for projects, or upon completion for short engagements.
Can I use the same template for all consulting services?
While possible, it's better to have variations. Strategy consulting might need project-based templates, while technical consulting might require detailed time tracking formats.
What file format should consultant invoices use?
PDF is the standard format as it preserves formatting across devices and can't be easily altered. Ensure PDFs are searchable and accessible.
