How IPO Bidding Works: Complete Process from Application to Allotment

Applying for an IPO in India is easy for beginners. Open a Demat account, link your bank, check open IPOs on your broker app, select lot size, bid at cut-off price (best for retail), approve UPI mandate or ASBA block, and wait for allotment. Funds stay safe and blocked only until final allotment. If you don’t get shares, money returns quickly. This IPO bidding process lets regular people like you own shares in new companies.

Imagine your friend calling excitedly: “A new company is going public – this could be a big opportunity!” You feel curious but also confused. When does bidding start? How do I apply? What is this cut-off price everyone talks about?

That excitement mixed with doubt is common. Thousands of first-time investors in Lucknow and across India face the same questions. The IPO bidding process looks complex at first, but it’s a well-regulated, fair system that helps companies find the right price while giving everyday investors a real chance.

Before applying for an IPO, investors should not only understand the bidding process but also check whether the company’s pricing is fair or expensive. To understand this better, read IPO Valuation Explained.

Why IPO Bidding is Needed & IPO Bidding Time in India

Companies don’t fix the price immediately. They use book-building through the bid system in an IPO to gauge demand and set a fair price. This process helps avoid under-pricing or over-pricing shares.

IPO application time: Bidding usually opens at 10:00 AM and closes at 5:00 PM on all days (including the last day). However, many banks and brokers have earlier cut-offs (2 PM to 4 PM) on the final day for processing. Always apply early to be safe.

The price band plays an important role in IPO bidding because investors must place their bids within this range. If you want to know how companies decide the IPO price before listing, read IPO Price Band Explained.

Cut-Off Price vs Bid Price – Clearing Beginner Confusion

This is one of the most common doubts in IPO bidding, explained.

• Cut-off price IPO: You don’t choose a specific price. You agree to buy at the final price decided after bidding ends. Retail investors (up to ₹2 lakh) can use this option. It gives you the highest chance of allotment because only bids at or above the final price qualify.
• Specific bid price: You pick a price within the band (e.g., ₹100–₹120). If the final price is higher than your bid, you may not get shares.

Tip for beginners: Always choose the cut-off price in mainboard IPOs for better odds.

UPI is beginner-friendly and works with apps like Groww, Zerodha, and PhonePe. ASBA is reliable for larger applications.

For retail investors, understanding the difference between the cut-off price and the bid price is very important because choosing the wrong bid price can affect allotment eligibility. To learn this in detail, read Cut-Off Price vs Bid Price in IPO.

How to Apply IPO via Net Banking (For ASBA Users)

1. Log in to your bank’s net banking (SBI, HDFC, etc.).
2. Go to e-Services→ IPO or ASBA section.
3. Select the IPO.
4. Enter details, choose cut-off, and confirm.
5. The bank will block the amount.

How to Modify or Cancel an IPO Bid

You can modify or cancel your bid before the issue closes (usually till 5 PM on the last day). In the broker app, go to your IPO bids → select the application → modify quantity/price or cancel. For UPI, you may need to place a fresh bid after cancellation. Act early, as last-minute changes can be risky.

If you prefer applying for an IPO through net banking, ASBA is a safe and reliable method where your money remains blocked in your bank account until allotment. For the complete process, read What is ASBA in IPO? 

IPO Mandate Failed / Rejected – Common Reasons & Solutions

Many users face this issue:

• Insufficient balance
• Wrong UPI ID
• Internet or bank server problem
• Mandate not approved in time
• Using a third-party UPI ID (not allowed)

Solution: Check the balance, verify the UPI ID, keep the internet stable, and approve immediately. If it failed, reapply before the cut-off. Funds are never deducted incorrectly.

How to Check IPO Allotment Status

Allotment usually happens 1-2 days after closing. Check easily:

• Registrar website (Link Intime, KFintech, MUFG) – enter PAN or application number.
• BSE website: bseindia.com → Investors → Application Status.
• NSE website or your broker app.

You’ll see if you got shares or not.

Retail vs HNI vs QIB Rules

Retail gets special protection with the lottery system.

SME IPO Bidding Difference

SME IPOs (on NSE Emerge or BSE SME) are for smaller companies:

• Higher minimum application size (often ₹1 lakh+).
• No cut-off price option (you must choose a specific price).
• Easier allotment, higher risk & volatility.
• Mandatory market maker for liquidity.

Mainboard IPOs are safer for absolute beginners.

Most beginners apply for IPOs through broker apps using UPI because the process is fast, simple, and mobile-friendly. If you are applying for the first time, read How to Apply IPO Using UPI & Demat Account.

What Happens After Allotment – The Listing Journey

If allotted, shares are credited to your Demat account before listing. On listing day, they start trading on NSE/BSE. You can sell immediately or hold. If not allotted, blocked money releases in 2-3 days. Track everything in your broker dashboard. Celebrate small wins and learn from every IPO.

After submitting an IPO application, if you make a mistake in lot size, bid price, or UPI details, there is no need to panic. You can modify or cancel your application before the issue closes, and the full process is explained in How to Modify or Cancel IPO Application.
