Every export of service creates a paper trail. Your goal is to preserve enough documentation to demonstrate the nature of the service, the payment received, and your compliance with tax regulations. Build the trail as work happens — not at year-end.
The Documentation Workflow
Ten stages, every one leaves a document behind. Each stage below maps to a card in the Document Library.
Why Documentation Matters
Compliance isn't built on memory. Documentation is what supports every GST claim, every Income Tax filing, and every response to a notice or query. The freelancers who sleep well at year-end are the ones who filed the paperwork as it arrived.
The Document Library
Every document you'll touch in a foreign-client engagement — what it is, why it matters, when it appears, and where to file it.
- 01
Client Agreement
What: The signed contract or Statement of Work that defines the engagement. Why: Anchors export-of-services treatment and scope. When: Before work begins. Where: Client folder →
Agreement/. Include scope, fees, currency and payment terms. - 02
Export Invoice
Open the Export Invoice BuilderWhat: The tax invoice raised on your foreign client. Why: Primary evidence of services rendered. When: At delivery, not on receipt of payment. Where:
Invoice/. Preserve both PDF and editable copies. - 03
Payment Confirmation
What: The platform receipt from Wise, Skydo, Payoneer or your SWIFT bank. Why: Links the invoice to a specific inward remittance. When: Immediately after each payment. Where:
Payment/. Save the PDF — screenshots aren't enough. - 04
Bank Credit Statement
What: The bank statement line showing the foreign inward remittance in INR. Why: Reconciles to the platform receipt and to FIRA. When: Monthly. Where:
Payment/alongside the platform receipt. - 05
FIRA
Open the Payments GuideWhat: Foreign Inward Remittance Advice — the digital confirmation of an export receipt. Why: Primary export-of- services evidence for GST and Income Tax. When: Within 30 days of each remittance. Where:
FIRA/. Do not wait until year-end — some platforms archive it early. - 06
FIRC
What: The older paper certificate covering the same information as FIRA. Why: Still accepted where the bank issues it. When: On request, per remittance. Where:
FIRA/. Compare below.
FIRA vs FIRC — quick reference
| FIRA | FIRC | |
|---|---|---|
| Format | Digital PDF | Paper certificate |
| Issuer | Bank or payment platform | Bank |
| Availability | Per remittance, on demand | On request; increasingly rare |
| Accepted for | GST + Income Tax + audit | GST + Income Tax + audit |
| Recommended | Default — collect one for every remittance | Only if your bank still issues it |
- 07
LUT (Letter of Undertaking)
LUT filing guideWhat: Annual undertaking that lets registered exporters invoice without IGST. Why: Substantiates the "Export under LUT — no IGST" note on your invoices. When: Once per financial year, before you raise your first export invoice. Where:
GST/. Keep the acknowledgement number too. - 08
GST Returns
What: Filed GSTR-1 and GSTR-3B, acknowledgements and working papers. Why: Compliance record and reconciliation source. When: Every filing cycle. Where:
GST/, sub-foldered by financial year. - 09
Income Tax Documents
What: ITR acknowledgement, computation sheet, advance tax challans, Form 26AS and AIS. Why: The complete year-end tax record. When: As each item is generated. Where:
Tax/, one folder per financial year.
Storage & Organisation
A simple, boring folder structure beats an elaborate one you never maintain.
// Recommended folder tree
Foreign Clients/
└── <Client Name>/
├── Agreement/
├── Invoice/
├── Payment/
├── FIRA/
├── Emails/
├── GST/
└── Tax/- Cloud storage: Google Drive, Dropbox or OneDrive — anywhere with versioning and share-links. Avoid keeping the only copy on a laptop.
- Naming convention:
YYYY-MM-DD_ClientCode_DocType_Description.pdfso files sort chronologically inside each folder. - Monthly backup: On the first of every month, mirror the current year's tree to a second location. Fifteen minutes now saves days at audit time.
Retention Guidance
What to keep, when it appears, and why it matters. Confirm the exact retention period with your tax adviser for your circumstances.
| When Generated | Why Keep It | |
|---|---|---|
| Agreement | Before work | Proof of engagement |
| Invoice | After work / at delivery | Revenue evidence |
| Payment Proof | Payment received | Bank reconciliation |
| FIRA | After remittance | Export documentation |
| GST Return | At filing | Compliance record |
| ITR | At filing | Tax record |
