Anybody there?

Yes, there are lots of people here, but sometimes you need to have a bit of patience. What kind of "custom page" are you referring to?

Yes of course @Watz. Thanks for your reply. Actually I thought might be I am in different timezone and no one is available right now.

So is this something that your employees are going to access in Netsuite? What is missing on the Customer-form?

I can share the wireframe.

If your employees have access to Netsuite, they can either access the customer through the standard interface or you probably need to develop a Suitelet-script that does what you need.

Let me share wireframe. I am very much confused.

Yes, but there are too many questions for me to help you.

Yes needs to be stored

Ok, can you not create it as an opportunity then?

I need to create this UI

ok, the easiest way is to create a custom form for opportunity then. But no, you cannot customize it completely. only the location of the fields and the grouping.

how to have that popup and other elements

If you need to make it look exactly like this then you need to develop your own suietlet

Ok, what excatly is that?

It's a type of script that is developed in Javascript.

Ok.

Look in the help of Netsuite on Suitelet.

I can write javascript

SuiteScript is basically Javascript with Netsuites own functions/modules.

so I need to write code externally and then upload on netSuite?

Yes

And I can use any coding editor or need specific one?

Netsuite has plugins for Eclipse and Webstorm to have a better workflow, but those aren't required.

ok

You might struggle if you know nothing about NetSuite etc. The learning curve isn't great.

Oh...

Pay a partner to help you

I can write code just need a right start

Hi Simar, Have a look here: https://netsuite.custhelp.com/app/answers/detail/a_id/43520 it shows details and examples for all possible script types. 'Suitelets' seem to have the most in common for your questions. it allows you to implement custom front and backends

Bah, there's a guy who has a book on NS coding that is generally more helpful, but I am struggling to remember his name

your first step will probably be Setting Up Your SuiteScript Environment followed by the SuiteScript 2.0 API Introduction (especially the SuiteScript 2.0 Hello World)

Can I achieve without Suitelet?

You should probably look <https:/system.netsuite.com/app/help/helpcenter.nl?fid=chapter_1518456405.html|SuiteScript 2.0 Custom Pages>

@battk I have shared wireframe/image that I want to create

a quick look at your wireframe suggests that it does not look like netsuite, so unless your requirements are very flexible, you will probably end up Using HTML

Where should I write and embed Code?

upfront, i dont think you can do this in a day

Alright. How much time it may take

several weeks probably... or months for me..:)

It is all explained if you search the documentation. if you do not want to create a full custom Suitelet than you can add custom UI components using inline HTML like battk mentiones. The inline HTML can also run client-side javascript if needed but it recommended to use the SuiteScriptTypes available to you from Netsuite to do the customization. These are less likely to break when updates arrive. SuiteScript is simply uploaded as a .js file.

Please suggest what should I tell my client genuinely?

my personal recommendation is to start going through those links i first gave

Tell your client you have no experience doing NetSuite development and it's going to take you a few weeks to even begin

Yes. Thanks gyus.

There is no other sane course of action

Yes I understand @PNJ.

unless you have experience using a frontend framework, i would estimate a timeline over a month with maybe somewhere in the middle where you have something that looks usable

I have web development experience in PHP and angular. But very new to netSuite.

i personally would ignore all estimates about timelines until you have a clear idea about the steps you would need to complete to get things running

@battk yes I understand and agree with you.
