Quick answer
List the writing services, number of articles or words where relevant, rate, project or publication details, applicable taxes, total amount, due date, and payment instructions.
Yes. Either model can work as long as the invoice clearly states the quantity, rate, and resulting amount so the client can verify the calculation.

Here's what a GST invoice looks like for a monthly content retainer:
Ishaan Kapoor — Freelance Writer
Delhi · GSTIN: 07XXXXX5566X1Z1
SAC: 998399 (Other Professional Services)
TAX INVOICE
INV-2026-0073 · Aug 2026
Writing & content services: SAC 998399
Covers blog writing, copywriting, ghostwriting, and general content services. GST rate: 18%.
Translation/interpretation work: SAC 998395
If part of your work is translation rather than original writing, this has its own dedicated code — also taxed at 18%.
Use CGST 9% + SGST 9% for clients in your own state, IGST 18% for clients in a different state (as in the example above). For international clients/publications, invoicing is generally zero-rated under an LUT.
| Service | Billing Unit | Typical Range (India) |
|---|---|---|
| Blog article (800-1200 words) | Per article | ₹1,000 – ₹8,000 |
| Long-form / SEO article (2000+ words) | Per article | ₹3,000 – ₹20,000 |
| Website copywriting (per page) | Per page | ₹2,000 – ₹15,000 |
| Ghostwriting (LinkedIn/social) | Per post | ₹500 – ₹5,000 |
| Monthly content retainer | Per month | ₹15,000 – ₹1,00,000 |
| Editing/proofreading | Per 1,000 words | ₹300 – ₹1,500 |
| Ebook / whitepaper writing | Per project | ₹15,000 – ₹75,000 |
State the word count and topic on every line item
"4 SEO blog articles (1,500 words each)" is far clearer than "Content writing services" — it helps clients verify the invoice against what was delivered.
Bill extra revisions as a separate, visible line item
If a client asks for a round of edits beyond what was agreed, add it as its own line ("1 additional revision round") rather than absorbing it silently — this trains clients to respect your scope.
Use a monthly retainer invoice for ongoing clients
For regular blog/content clients, one predictable monthly invoice (e.g. "4 articles — August 2026") is easier for both sides to track than invoicing per individual piece.
Clarify usage rights for ghostwritten content
If you’re ghostwriting under someone else’s byline, note that authorship/usage rights transfer fully to the client upon payment — this is standard practice worth stating explicitly.
Set Net 15 or Net 30 terms and stick to them
Publications and agencies often have longer payment cycles — agree terms upfront (Net 15/30) and reference them on every invoice rather than leaving due dates vague.
Writing, copywriting, and content services generally fall under SAC 998399 (other professional, technical and business services), taxed at 18%, unless the work is more specifically classifiable — for example, translation work has its own dedicated SAC (998395).
All three are common — per-word or per-article works well for one-off content pieces, while a monthly retainer suits ongoing relationships (e.g. a fixed number of articles or hours per month). Whichever you choose, state the basis clearly on the invoice so the client can verify the calculation.
Most freelance writers include one round of revisions in the base price and bill additional rounds separately, similar to design work — stating this upfront in your proposal or on the invoice itself avoids unpaid extra drafts.
