Government and PSU procurement in India is a multi-trillion rupee market. Every year, hundreds of thousands of companies — from large EPC contractors to small IT vendors — submit tender bids in response to RFPs from central and state governments, PSUs, and autonomous bodies.
The formal tender submission process (GeM portal, CPP portal, state e-procurement systems) handles the official submission. But a significant volume of pre-tender communication, clarification documents, supplementary technical submissions, and post-bid correspondence still happens over email and WhatsApp — where file size limits and security gaps create real problems.
Here is how to handle tender document sharing professionally when standard channels fall short.
Where Standard Channels Fall Short in Tender Processes
Government email systems often have strict attachment limits — sometimes as low as 10 MB for .gov.in addresses. A comprehensive technical bid with engineering drawings, certifications, and financial statements can easily be 100–500 MB.
Official e-procurement portals handle the formal submission but often have their own file size limits and accepted formats. Supplementary documents, clarifications, and pre-bid queries may need to be submitted through alternate channels.
WhatsApp is used informally between vendor and procurement contact, but provides no formal record and compresses images — problematic for technical drawings and certificate scans that must be legible.
Courier / physical submission adds 1–5 business days and is not appropriate for time-sensitive clarification documents.
What Goes in a Typical Government Tender Submission Package
Different tenders have different requirements, but a technical bid typically includes:
- Technical specification compliance — point-by-point response documents (50–200 pages PDF)
- Engineering drawings and schematics — CAD-generated PDFs and prints (100 MB–2 GB)
- Product certifications — BIS, ISO, CE, and other certificates (scanned PDFs)
- Company credentials — registration certificates, GST certificate, PAN card, incorporation documents
- Financial statements — audited accounts for 3 years
- Experience certificates — previous project completion certificates from clients
- Performance security — bank guarantee formats
- Pre-qualification documents — EMD payment receipts, power of attorney
A complete technical bid package can range from 50 MB to over 1 GB depending on the tender's scope and the drawings involved.
The Right Approach for Supplementary Document Submission
When the official portal submission is complete but supplementary documents need to go to the procurement committee or client separately:
Step 1: Compile and name documents clearly
Organise your supplementary documents with clear, formal file names:
TenderRef-2026-047_Technical_Compliance_Matrix.pdfTenderRef-2026-047_Drawings_Package.zipTenderRef-2026-047_ISO_9001_Certificate.pdf
Step 2: Upload as a single organised transfer
Upload all supplementary documents to QikDrive as one transfer. This creates a single organised package — not a cascade of email attachments.
Step 3: Set appropriate access controls
- Password: The tender reference number is a natural choice — both parties know it
- Download limit: Set to 3 — one for the procurement officer, one for the evaluator, one for the file copy
- Expiry: Match to the bid evaluation timeline (typically 14–30 days after submission)
Step 4: Send formally
Include the link and password in a formal email to the procurement committee email address on record. Reference the tender number, submission date, and what is included. The email serves as the formal correspondence record; the link provides the file access.
Pre-Bid Query and Clarification Documents
The pre-bid period — where vendors can submit queries and the procuring authority issues clarifications — often involves document exchange that does not go through the portal:
- Vendors send technical queries with supporting diagrams
- The authority issues written clarifications sometimes with revised drawings
- Corrigenda and addenda are distributed to all registered bidders
For vendors sending query documents above 10 MB (common when technical drawings are included), a file transfer link with the procurement committee's reference allows the document to be accessed by all relevant evaluators without email size limits.
For authorities distributing clarifications to 50+ registered bidders, a single download link can be shared to all bidders simultaneously — cleaner than 50 individual emails with large attachments.
Maintaining an Audit Trail
In government procurement, documentation of what was submitted and when is critical for dispute resolution, audit, and RTI responses.
When sharing documents via a secure transfer link:
- Keep a record of the short link and the email in which it was shared
- Note the download limit set and the expiry date
- Screenshot the transfer dashboard showing upload date and file list
- Store this alongside your bid submission records
This creates a defensible record that the documents were prepared, uploaded, and shared on a specific date — with specifics about what files were included.
Security Considerations for Tender Documents
Tender documents — particularly financial bids, proprietary technical solutions, and pricing strategies — are commercially sensitive. Inadvertent disclosure before bid evaluation is a serious problem.
Key protections:
- Password protection — the link alone is not enough to access documents
- Download limits — restrict access to the intended evaluation team
- Expiry — documents do not remain accessible beyond the evaluation period
- No account required on receiving end — procurement officers at government bodies should not need to create accounts in private services to access bid documents
These protections are significantly more robust than an email attachment, which can be forwarded to anyone without your knowledge.
Frequently Asked Questions
Can I submit tender documents through QikDrive instead of the official portal?
No. Official tender submissions must go through the designated procurement portal (GeM, CPP, state e-procurement systems). QikDrive is appropriate for supplementary documentation, pre-bid clarifications, and post-bid correspondence that falls outside the portal's file size limits.
How do I send a 500 MB technical bid package to a government client when email bounces?
Upload to QikDrive, password-protect with the tender reference number, set a 14-day expiry, and share the link in a formal email to the procurement committee address. Include the password in the same email or communicate it separately by phone.
Is it safe to share proprietary technical documents via a file transfer link?
Yes, with password protection, download limits, and expiry. The link without the password is inaccessible. After expiry, the link deactivates automatically. This is significantly more controlled than an email attachment that can be forwarded indefinitely.
How long should I keep tender document links active?
Match the expiry to the bid evaluation timeline — typically 14–30 days from submission. After evaluation is complete, the link deactivates automatically.
Can I send pre-bid clarification documents to multiple bidders from one link?
Yes. A single transfer link can be shared with multiple recipients. Set a generous download limit (or no limit) if you are distributing to all registered bidders. Set an expiry matching the pre-bid clarification period.
What is the maximum file size I can share for tender documents?
5 GB on the free plan. 20 GB on Pro (₹99/month). 100 GB on Business (₹299/month). Sufficient for all standard tender document packages including large drawing sets.
