What is a proforma invoice?
A proforma invoice is a preliminary bill shared before a sale is finalized. It helps explain price, items, taxes, and terms before issuing a final invoice.
Before a freelance project officially starts, corporate clients often ask for a "Proforma Invoice." If you're used to only sending an invoice after the work is completed, this can be confusing.
Unlike a standard Tax Invoice, a Proforma Invoice does not trigger a demand for immediate payment, and it is not a legally binding financial document for accounting purposes. Your client cannot use a proforma invoice to claim Input Tax Credit (ITC) for GST.
| Feature | Proforma Invoice | Tax Invoice |
|---|---|---|
| Purpose | Pre-delivery cost estimate | Official demand for payment |
| Legal Status | Not legally binding | Legally binding |
| ITC Claim | Cannot be used for ITC | Can be used to claim ITC |

Freelancers and agencies typically send a Proforma Invoice in the following situations:
- Advance Payments: When you require a 50% upfront deposit to begin work, corporate clients often need a Proforma Invoice to process the advance payment internally.
- Budget Approval: When a client's finance team needs to approve the estimated cost of your project before they can issue an official Purchase Order (PO).
- Scope Agreement: To clearly outline the expected deliverables, timelines, and costs so there are no surprises once the final Tax Invoice is issued.
What to include before client approval
To prevent scope creep and ensure smooth approval, your Proforma Invoice must include:
- Clear label stating "PROFORMA INVOICE" at the top.
- Date of issue and validity period (e.g., "Valid for 30 days").
- Detailed breakdown of services, estimated hours, and rates.
- Estimated GST calculations based on the expected place of supply.
- Payment terms and conditions for the advance deposit.
Common mistakes freelancers should avoid
- Recording it as Income: Never log a Proforma Invoice as income in accounting software like Tally. Wait for the actual payment or the final Tax Invoice.
- Using the Same Invoice Number: Do not use your standard Tax Invoice numbering sequence for Proforma Invoices. Use a separate sequence like "PRO-001".
- Forgetting the Validity Date: Always add an expiration date to protect yourself against price changes if the client delays approval for months.
