Invoice nonprofits and organisations for grant writing, research, and reporting services. Get paid on time with Tidybill.
A grant writer invoice documents fees for researching, writing, and submitting grant funding applications on behalf of non-profit organisations, charities, arts organisations, educational institutions, and social enterprises. Grant writers help clients identify suitable funders, develop compelling funding narratives, and meet the specific requirements of each funder's application process. Because grant writing work is not contingent on the grant being awarded (fee-on-success arrangements are generally considered unethical in this field), invoices document professional services rendered regardless of the outcome. Fees are typically charged as a flat project fee per application, a retainer covering multiple applications, or an hourly rate for research and strategy work.
| Service | Typical Rate | Unit |
|---|---|---|
| Grant Application Writing (major foundation) | £500 - £2,500 | per application |
| Grant Application Writing (small/local fund) | £200 - £800 | per application |
| Grant Research & Prospect List | £200 - £800 | per project |
| Grant Reporting (interim or final) | £200 - £600 | per report |
| Grant Writing Retainer (3+ apps/quarter) | £600 - £2,000 | per month |
| Strategy Consultation | £60 - £120 | per hour |
Invoice per application on submission, regardless of the outcome. For retainer arrangements covering multiple applications and reporting, invoice monthly. Research and prospect identification work is invoiced separately as a distinct phase before writing begins. Avoid any success-fee arrangements as these violate grant-making ethics guidelines. Net 14 to Net 30 depending on client size and their invoicing cycle.
