Last Updated May 14, 2025

Freelancers need to submit an invoice that includes essential documents such as a detailed description of services provided, the agreed-upon payment terms, and the freelancer's tax identification information. Including a unique invoice number and the date of issue is crucial for proper record-keeping and payment tracking. Clear contact details for both the freelancer and the client ensure smooth communication and reduce the chance of payment delays.

What Documents Does a Freelancer Need to Submit an Invoice?

Number Name Description
1 e-KYC Verification Freelancers must complete e-KYC verification by submitting government-issued identification such as a passport or driver's license along with proof of address like a utility bill to authenticate their identity before issuing an invoice. This process ensures compliance with financial regulations and facilitates secure payment transactions.
2 Digital Work Order Freelancers must submit a digital work order alongside their invoice to clearly detail the scope of services rendered, project milestones, and agreed payment terms. This document enhances transparency and serves as a critical reference for both parties during payment processing and project verification.
3 Smart Contract Agreement Freelancers need to submit a Smart Contract Agreement alongside their invoice to ensure clear terms of service, payment milestones, and deliverables are legally acknowledged and enforced. This document streamlines payment processing by automatically triggering transactions once contract conditions are met, reducing disputes and enhancing transparency.
4 E-signature Authorization Freelancers need to include an e-signature authorization on their invoices to ensure legal validity and secure client approval digitally. This electronic authorization verifies identity and consent, streamlining payment processing while maintaining compliance with digital transaction regulations.
5 Vendor Onboarding Form Freelancers must submit a completed Vendor Onboarding Form along with their invoice to ensure accurate vendor information and payment processing. This form typically includes essential details such as tax identification, banking information, and contact data required by the client for compliance and record-keeping.
6 PO (Purchase Order) Reference A freelancer needs to include a Purchase Order (PO) reference on the invoice to link the billing to the client's authorized purchase agreement, ensuring accurate payment processing and contract compliance. The PO number acts as a crucial identifier for both parties, streamlining invoice verification and reducing payment delays.
7 Timesheet Blockchain Log Freelancers need to submit a detailed timesheet blockchain log as part of their invoice documentation to provide verifiable proof of hours worked, ensuring transparency and trust in payment processes. This blockchain-based timesheet securely records time entries and project milestones, enhancing accuracy and reducing disputes with clients.
8 Virtual Bank Account Details Freelancers must include virtual bank account details such as the account number, bank name, and branch code on their invoices to ensure accurate and timely payment processing. Clear presentation of these details reduces payment errors and supports smooth financial transactions between clients and freelancers.
9 Electronic Service Report Freelancers need to submit an Electronic Service Report alongside their invoice to provide detailed documentation of the completed work, including hours logged and specific tasks performed. This report ensures transparency and serves as proof of service for both the freelancer and the client, facilitating accurate payment processing.
10 QR Code Payment Request Freelancers need to include a detailed invoice containing their tax identification number, client information, service description, payment terms, and a QR code payment request to facilitate seamless and secure transactions. The QR code enables clients to quickly scan and complete payments using compatible banking or payment apps, enhancing efficiency and reducing manual errors.
