What is the last time to apply for an IPO on the closing day?

The official exchange cut-off is 5:00 PM for retail investors, but most brokers close earlier. Zerodha stops accepting orders at 4:45 PM, and UPI mandates must be approved by 5:00 PM. To be safe, submit before 3:00 PM.

Can I apply for an IPO after 5:00 PM?

No. The exchange window closes at 5:00 PM, and applications submitted after that are not accepted. Some platforms may allow pre-apply for the next day, but the bid will be processed only when the window opens.

What happens if I don't approve the UPI mandate on time?

Your application will be rejected. The UPI mandate must be approved by 5:00 PM on the closing day. If you miss it, the bid is invalid and funds are not blocked.

Do different brokers have different IPO bidding times?

Yes. Brokers may close earlier than the exchange. For example, Zerodha closes at 4:45 PM, while the exchange window is until 5:00 PM. Always check your broker's specific cut-off.

Is there a pre-apply option for IPOs?

Some brokers like Zerodha offer a pre-apply window one day before the IPO opens. You can submit your application early, but it will be processed only when the bidding window opens. Early application does not increase allotment chances.

IPO Bidding Time: A Complete Guide to Application Windows and Cut-offs

IPO bidding time is the official window when investors can submit applications for shares in an initial public offering. On Indian exchanges, the standard window runs from 10:00 AM to 5:00 PM on trading days, but brokers and banks often impose earlier internal cut-offs, especially on the closing day. Missing these cut-offs is a leading cause of application rejection.

Key Takeaways

The standard exchange window for IPO bidding is 10:00 AM to 5:00 PM on trading days.
Brokers like Zerodha close applications at 4:45 PM, and UPI mandates must be approved by 5:00 PM on the last day.
Bank ASBA platforms may have their own earlier deadlines, so always check your intermediary.
Applying before 3:00 PM on the closing day reduces the risk of processing delays.

#What Is IPO Bidding Time and Why Does It Matter?

IPO bidding time is the period when investors can submit bids for shares in an IPO. It matters because applications submitted after the cut-off are rejected, and funds may remain blocked unnecessarily. The standard exchange window is 10:00 AM to 5:00 PM on trading days, but the effective deadline for most retail investors is earlier due to intermediary processing times.

#How does the IPO bidding window work?

During the bidding window, investors can place bids through their bank's ASBA facility, a broker app, or a UPI-based platform. The exchange accepts bids only during the prescribed hours. Once a bid is placed, it must be verified and submitted to the exchange within the order placement window. Only after this will the investor receive a mandate request to block funds, which may take up to a few minutes.

#Why are there different cut-offs for exchanges, brokers, and banks?

Exchanges set the broad window, but brokers and banks process applications in batches and need time to forward them. For example, Zerodha stops accepting IPO orders at 4:45 PM, while the exchange window closes at 5:00 PM. Banks may stop accepting ASBA applications even earlier, sometimes by 3:00 PM on the closing day. These earlier cut-offs are necessary to ensure the application reaches the exchange before the official deadline.

#Before You Start: Prerequisites and Risk Awareness

Before bidding in an IPO, you need a Demat account, a bank account with ASBA or UPI enabled, and sufficient funds to cover the bid amount. Your PAN must be linked to your Demat account, and your UPI app should be active and linked to the same bank account used for the application. Applying at the last minute carries risks such as server load, mandate delays, and funds being blocked for longer than necessary.

#What do you need before bidding in an IPO?

A Demat account with a registered depository participant.
A bank account with ASBA facility or UPI enabled.
Sufficient balance to cover the application amount.
PAN linked to the Demat account.
Active UPI app with the correct UPI ID.

#What are the risks of applying at the last minute?

Last-minute applications may fail due to high server load on the broker or bank platform. UPI mandate requests may be delayed, and if the mandate is not approved before the cut-off, the application is rejected. Funds remain blocked until allotment is finalized, so a rejected application can still tie up your money for several days.

#Step 1: Prepare Your Application Details

Before opening the bidding platform, decide the number of lots you want to apply for and the bid price. For book-built issues, choose a price within the price band. Ensure that your name, PAN, and bank details match exactly across all platforms to avoid rejection.

#How to choose the number of lots and bid price?

Check the lot size and the price band from the IPO prospectus.
Decide how many lots fit your budget.
For book-built issues, you can bid at any price within the band, but the cut-off price is determined later.
For fixed-price issues, everyone bids at the same price.

#What details must match your bank and Demat records?

Your name, PAN, and bank account number must be identical in the application, Demat account, and bank records. Even minor spelling differences can lead to rejection. If applying through a broker app, double-check the UPI ID associated with your bank account.

#Step 2: Choose Your Platform or Intermediary

You can apply for an IPO through a broker app, bank ASBA, or UPI-based platform. Each has different cut-off times and processing delays. Choose one you are familiar with to reduce errors.

#Broker app vs. bank ASBA vs. UPI app: what are the differences?

Platform	Typical cut-off	Processing
Broker app (e.g., Zerodha)	4:45 PM on closing day	Same day if during market hours
Bank ASBA portal	Varies, often earlier than 5:00 PM	Batch processing
UPI-based app	Mandate approval by 5:00 PM	Immediate mandate request

Broker apps offer convenience but may close earlier. Bank ASBA portals may accept applications until 5:00 PM, but internal cut-offs can be earlier. UPI-based applications require mandate approval by 5:00 PM on closing day.

#How do cut-off times vary by platform?

Zerodha accepts IPO orders from 10:00 AM to 4:45 PM on trading days, with a pre-apply window one day before. Bank ASBA platforms may accept applications until 5:00 PM, but many banks stop accepting earlier to process the applications. UPI mandates must be approved by 5:00 PM on the closing day; otherwise, the application is invalid.

#Step 3: Complete the Main Bidding Process

After choosing your platform, enter your bid details and submit. You will receive a UPI mandate request or an ASBA block confirmation. You must approve the mandate immediately; failure to do so invalidates the bid. The application is then sent to the exchange for processing, which may take minutes to hours.

#How to submit the bid and authorize the mandate?

Log in to your chosen platform.
Select the IPO and enter the number of lots and bid price.
Submit the application.
Wait for the UPI mandate request on your UPI app.
Approve the mandate by entering your UPI PIN.
Note the application reference number.

#What happens after you press submit?

After submission, the platform sends the application to the exchange. If using UPI, the NPCI sends a mandate request to your UPI app. You must approve it. If you don't receive the mandate request within an hour, delete and resubmit the application. Once approved, the funds are blocked in your account until allotment.

#Step 4: Confirm and Safely Wrap Up

After submitting your application, verify its status on the broker or registrar portal. If the UPI mandate doesn't arrive within an hour, delete and resubmit the application. Keep funds blocked until allotment is finalized, and note the refund timeline if not allotted.

#How to verify your application status?

Check the application status on your broker's platform or the registrar's website. You should see a confirmation that the application has been submitted and the mandate approved. If the status shows "pending" or "not received," take corrective action immediately.

#What to do if you don't receive the mandate request?

If the UPI mandate request doesn't arrive within an hour of submission, delete the application and resubmit it. This ensures a fresh mandate request is generated. Do not wait until the last minute, as the resubmission must also be processed before the cut-off.

#Common Mistakes to Avoid When Bidding in an IPO

Common IPO bidding mistakes include submitting after the broker's cut-off on the last day, not approving the UPI mandate before 5:00 PM, mismatching personal details, and having insufficient funds. All of these can lead to rejection.

#Why do applications get rejected?

Applications are rejected for several reasons: details mismatch between application and bank records, insufficient funds, failure to approve the UPI mandate, or submission after the cut-off. Technical errors during submission can also cause rejection.

#What are the most frequent timing errors?

Submitting after the broker's cut-off on the last day.
Not approving the UPI mandate before 5:00 PM.
Assuming the exchange window applies to all platforms.
Waiting until the last hour, leaving no buffer for processing.

#Safety Tips for IPO Bidding

Only use SEBI-registered brokers and official bank apps for IPO applications. Never share your UPI PIN or OTP with anyone. Verify the mandate amount and merchant name before approving. Keep a record of your application reference number.

#How to protect your funds and personal data?

Use only official apps and websites.
Never share your UPI PIN, OTP, or banking passwords.
Verify the mandate amount and merchant name before approving.
Keep screenshots of your application and mandate approval.

#What are the risks of using unknown platforms?

Unknown platforms may be fraudulent and can steal your personal data or funds. They may not be registered with SEBI, and your application may never reach the exchange. Always verify the platform's registration and use official sources.
