Custom CRM development · Udupi & Mangaluru
A CRM where every enquiry gets its follow-up
We build sales CRMs for businesses in Udupi, Mangaluru and along the coast: every call, WhatsApp and web enquiry in one list, and the next follow-up on the right phone. We plan it with your sales team and keep supporting it after launch.
- Your stages, your words
- the pipeline your team already talks in
- On every phone
- for staff in the office and out on visits
- Leads first
- enquiries and reminders go live before the rest
- Yours to keep
- source code, customer list and hosting account
In short
What is a custom CRM?
A custom CRM (customer relationship management system) is sales software made for one company's way of selling, rather than an off-the-shelf app the team must adjust to. It keeps every enquiry, the stage each deal has reached and who has to follow up next. Whirl Designs builds them at its Udupi studio for sales teams across Mangaluru and coastal Karnataka, and each business keeps the system and its data.
Start here
A shared sheet, a ready-made CRM, or your own?
Plenty of teams do not need a custom CRM yet. These are the three honest options, from the simplest up.
A ready-made CRM app
Best for: Selling the standard way: enquiry, call, close
- Ready to use within days
- Email, contacts and basic reports come built in
- Your team works the way the app is laid out
A CRM built for you
Best for: Selling that a standard pipeline does not fit
- Site visits, customer tiers, repeat orders or dealers built in
- Shares data with your billing, stock and WhatsApp
- The code and the customer list stay with you
At the first meeting we will say which of the three fits you, even when it is not the one we build.
Our work
The CRM an agri business runs its day on
Nityanand Agro
Agriculture & retail · Karnataka
Nityanand Agro sells agri products in Karnataka. Beside its public catalogue website, the business needed an internal system its staff could run the whole working day on, covering customers, sales and the stock behind them, on their phones and in places where the signal comes and goes.
It runs in the browser and installs like an app, so staff put it on their home screens without going through a store. Each customer belongs to a tier that decides what they are billed, and every sale moves the stock with it.
- Customer-tier pricing, with a sensible fallback when a tier has no figure set
- Bills with or without GST, and receipts from a Bluetooth thermal printer paired with the phone
- Sales, returns, transfers and write-offs all keep the stock count right
- Keeps working over patchy rural signal, with caching that rides out a dropped connection
Also built by us

Padmavathi Tours & Travels
Travel & transport · Udupi

What you get
Six parts of every CRM we hand over
Your stages and fields will differ from the next business. These six parts come with every CRM, and each is listed in the plan before work starts.
- One list for every enquiryWebsite forms, WhatsApp, phone calls, walk-ins and marketplace leads land in the same list, each tagged with where it came from, so no enquiry sits unseen on one salesperson's phone.
- A pipeline in your own wordsThe pipeline is the row of stages a deal moves through, named the way your team talks: site visit, sample sent, advance received. A deal moves on with a drag on the computer or a tap on the phone.
- Reminders with a name on themEach follow-up has an owner and a time. The reminder reaches that person's phone, and the manager can see which ones are overdue and whose they are.
- Proposals that become billsProposals, proforma invoices and bills are made from the customer's record on your own letterhead, as a PDF for WhatsApp or email. When a customer accepts a proposal, it turns into the bill without retyping a line.
- Who sees which leadsSalespeople see their own leads, branch heads see their branch and the owner sees everything. Each call, note and stage change shows who logged it and when, so the history of any deal can be traced.
- Reports for the weekly sales meetingEnquiries by source, deals by stage, deals won and lost with the reason, missed follow-ups and sales by person, ready on one screen before the meeting starts.
How it runs
How your CRM goes live
Your team keeps selling the old way until the new CRM has proved itself on real enquiries.
We trace a real enquiry
From the first call or message to the final bill, we follow how enquiries move today, who touches each one and where they go quiet.
Stages and fields in writing
The plan lists your pipeline stages, the fields a salesperson fills in, the reminders, roles and reports, and which of them comes first. Nothing is built until you have read it and agreed.
Your old contacts, cleaned and moved
Lists from spreadsheets, phone contacts or an old CRM are cleaned, duplicates are merged and the records imported. You check a sample before anyone works from it.
Enquiries and reminders first
The enquiry list, the pipeline and the reminders go live first, and your team uses them on real leads while the rest is built.
Messages and reports next
WhatsApp messages, links to billing and the sales reports follow in stages. After launch, the people who built the CRM handle fixes and changes.
Not a fit
When you do not need a custom CRM
Any one of these is a good reason to wait.
- Enquiries are few and one person handles them all. A shared sheet and steady WhatsApp habits are enough for now.
- You mainly want to send offers by email or SMS to a long list. A mailing tool does that job; a CRM is for following up one enquiry at a time.
- No one will keep it up to date. A CRM works only when salespeople log calls and move deals, and a manager checks it every week.
- You need more enquiries, not a place to keep them. A clear website and a well-kept Google Business Profile come first.
Questions
Questions about custom CRM development
How long does a custom CRM take to build?
A first version with the enquiry list, pipeline and reminders is usually in use within four to eight weeks. With WhatsApp messages, billing links and reports added one by one, the full CRM usually takes two to four months. More lead sources, branches or systems to link make the job bigger, and quick feedback from your team keeps it moving.
Is a ready-made CRM app enough for a small business?
Often, yes. If your team sells the standard way, from enquiry to call to close, a ready-made CRM will do the job and we will help you choose one. Building your own makes sense when your selling has steps those apps do not fit, such as site visits, customer tiers or repeat orders, or when the CRM must share data with your billing and stock.
Can the CRM send WhatsApp messages to customers?
Yes, through the official WhatsApp Business API. Follow-ups, receipts and reminders go out from the CRM itself. A message sent more than 24 hours after the customer last wrote to you must use a template that WhatsApp has approved, so we set those templates up with you. Jayalaxmi Jewellers sends receipts and reminders from its retail system this way.
Can leads from our website, IndiaMART or Justdial come in on their own?
Yes, for most sources. Website forms feed straight in, and IndiaMART offers a lead feed that passes each new buyer enquiry to outside software. Where a source only sends enquiries by email, the CRM can often read them from that inbox. We check what each source allows before promising a link, and phone enquiries are added in a few taps.
Can we move our contacts from Excel or an old CRM?
Yes. Spreadsheets, contacts saved on salespeople's phones and exports from an old CRM can all be brought in, with duplicates merged along the way. Past call notes and deal history can usually come across too, if the old system lets you export them. Your team keeps using the old list until the new one has been checked.
Will the CRM work on salespeople's phones with weak signal?
Yes. It runs in the phone's browser, installs on the home screen and is built to load on a weak connection and hold on to what was typed when the signal drops. Nityanand Agro's staff use their system this way over patchy rural signal. Before launch, we try each screen on the handsets your salespeople carry.
Who owns our customer data in a custom CRM?
Your business does, along with the CRM itself. The code, the customer database and the hosting account are registered to your business, and you can export the full customer list at any time. Everyone logs in with their own password, a backup copy is kept off the server, and when a salesperson leaves, their customers and call history stay with you.
Can the CRM be in Kannada?
Yes. Staff screens, reminders and customer WhatsApp messages can use Kannada, English or a mix of the two. Our studio is in Udupi, so sales teams in Manipal, Mangaluru, Karkala and Kundapura can be trained face to face, in the language they sell in. Teams further away learn the CRM over video calls instead.
