Problems we solve

Are leads slipping through the cracks?

Most growing businesses don't lack leads. They lose them between WhatsApp chats, spreadsheets and inboxes, and nobody can see the full picture.

  1. 01

    Leads scattered everywhere

    Enquiries arrive by website, phone, WhatsApp, email and referrals, and end up in personal phones and spreadsheets.

  2. 02

    Follow-ups that never happen

    Without reminders and ownership, warm leads go cold and nobody notices until the deal is lost.

  3. 03

    A CRM that doesn't fit

    Off-the-shelf tools force your team into someone else's process, so they stop using it and go back to Excel.

  4. 04

    Reports nobody trusts

    Sales numbers are pieced together by hand every month, so decisions are made on guesses.

Our solution

A CRM that matches your process, so your team actually uses it

We start with how your business really sells, then build the CRM around it: your stages, your approvals, your reports, and the tools your team already uses.

  • A business problem, not a software purchase

    Lost leads and slow follow-ups cost revenue. We map where enquiries come from, who handles them and where they get stuck, before writing any code.

  • How we approach it

    We build the core pipeline first and put it in your team's hands early, then add automation, integrations and reports in short iterations based on real use.

  • Adoption is part of the project

    A CRM only works if people use it. We keep screens simple, train your team, and fix friction in the first weeks after launch.

CRM development services

What we build

Custom CRM software development covers more than a contact list. These are the CRM development services we offer, from a first sales pipeline to a system that runs your customer operations.

01

Custom CRM software development

A CRM designed from scratch around your sales and service process: your fields, your pipeline stages, your approval rules and your reports. It runs in the browser and on phones, and grows with you instead of charging per seat for features you never use.

  • Custom pipeline stages and fields
  • Contact and company records
  • Activity timeline for every lead
  • Tasks, reminders and follow-ups
  • Mobile-friendly for field teams
  • Your branding and your domain
02

Lead management and sales pipeline

Capture leads from every channel automatically, assign them to the right person, and track every deal through your stages. Managers see what is moving and what is stuck without asking for updates.

  • Website and landing page form capture
  • Rule-based lead assignment
  • Lead scoring and qualification
  • Duplicate detection
  • Kanban and list pipeline views
  • Win and loss reasons
03

CRM integrations

Connect the CRM to the tools your business already runs on, so data flows automatically instead of being copied by hand. We integrate with messaging, email, accounting, payment and ERP systems through their official APIs.

  • WhatsApp Business messaging
  • Email and calendar sync
  • Accounting and invoicing tools
  • Payment gateways
  • ERP and inventory systems
  • Telephony and call logging
04

Quotations, approvals and documents

Generate quotations and proposals from CRM data, route them for approval and track their status. Standard documents are created in seconds instead of being rebuilt in Word every time.

  • Quotation and proposal templates
  • Approval workflows
  • PDF generation
  • Version history
  • Discount and pricing rules
  • E-signature integration where needed
05

Customer portals

Give clients a secure portal to see their projects, documents, approvals and invoices, so your team answers fewer status questions. We build this kind of portal in our own product, Social Sphere CRM.

  • Client login per account
  • Approval and feedback flows
  • Document and file sharing
  • Status tracking
  • Notifications by email
  • Full audit trail
06

CRM migration and modernisation

Move from spreadsheets, an old CRM or an off-the-shelf tool you have outgrown. We clean and map your data, migrate it with checks at every step, and run the old and new systems side by side until your team is confident.

  • Data cleaning and de-duplication
  • Field and stage mapping
  • Migration from Excel or other CRMs
  • Parallel run before switch-over
  • Team training
  • Post-launch support
07

Reports, dashboards and automation

Turn CRM data into dashboards that answer real questions: where leads come from, which sources convert, how long deals take and who needs help. Routine work such as reminders, assignments and status updates runs automatically.

  • Sales and source dashboards
  • Team performance views
  • Scheduled email reports
  • Automated reminders and escalations
  • Data export
  • AI-assisted lead summaries, where useful

Our approach

How we build a CRM your team will use

Every CRM is different. The way we build one isn't. Open each step to see what it covers.

  1. 01.Process mapping

    We map how leads arrive, who handles them, the stages they pass through, the approvals involved and the reports you need.

  2. 02.Data model and workflow design

    Fields, stages, roles, automation rules and integrations, agreed in writing before design starts.

  3. 03.Core pipeline first

    The essential lead and deal flow is built and handed to your team early, so real use shapes everything after it.

  4. 04.Integrations and automation

    Website forms, WhatsApp, email, accounting or ERP connections, plus reminders, assignments and escalations.

  5. 05.Data migration and training

    Existing data is cleaned and moved with checks, and your team is trained on the workflows they will use every day.

  6. 06.Launch and improvement

    A supported launch, then improvements based on how the team actually uses the system in its first weeks and months.

Custom CRM vs off-the-shelf

Should you build a custom CRM or buy one?

Off-the-shelf CRMs suit many businesses. A custom CRM makes sense when your process is your advantage. This is how the options compare.

Guide

Custom CRM development: a practical guide for business owners

What is a custom CRM?

A CRM (customer relationship management system) keeps track of leads, customers, conversations and deals in one place. A custom CRM is built specifically for your business, around your own sales stages, fields, approvals and reports, instead of adapting a general-purpose product.

Because it is built for you, a custom CRM can include exactly the screens each role needs, connect to the tools you already use, and leave out the features you would never touch. You own the software and the data.

Custom CRM or off-the-shelf: how to decide

An off-the-shelf CRM is a good choice when your sales process is standard and the product fits it with light configuration. It is fast to start and comes with a large ecosystem of add-ons.

A custom CRM makes sense when your process is a competitive advantage, when you need deep integration with other systems such as ERP or accounting, when per-user licences are becoming expensive as the team grows, or when your team keeps working around the tool instead of in it.

Features every business CRM needs

At its core, a CRM needs contact and company records, a pipeline with clear stages, tasks and reminders, an activity history for every lead, and reports on sources, conversion and team performance.

Beyond that, the right features depend on how you sell: quotations and approvals for B2B, site-visit scheduling for real estate, admission follow-ups for education, or client portals for agencies. Building only what you need keeps the system simple enough for everyone to use.

WhatsApp, email and website integration

Many businesses in India receive most of their enquiries on WhatsApp. Integrating the WhatsApp Business API lets the CRM capture those conversations, send approved templates and keep messages linked to the right lead.

Website and landing page forms should send leads straight into the CRM with their source, so you can see which channels bring real business. Email and calendar sync keep meetings and conversations on the lead's timeline.

Moving your data into a new CRM

Data migration is where many CRM projects stumble. Existing spreadsheets and old systems usually contain duplicates, inconsistent formats and missing fields, so the data needs to be cleaned and mapped before it is moved.

A safe migration moves data in stages, checks counts and samples after each step, and keeps the old system available until the team has confirmed everything is correct.

Security and access control

A CRM holds sensitive information about customers and deals. Role-based access control ensures each person sees only what their role needs, and audit logs record who viewed or changed what.

Hosting in your own cloud account, regular backups, encrypted connections and two-factor login for administrators are basic protections every business CRM should have.

When a CRM should grow into an ERP

A CRM manages customers and sales. When orders, inventory, production, purchasing and accounting also need to be connected, a business is often moving towards an ERP.

A custom CRM can be designed so that it connects to an ERP later, or grows into one module by module, without throwing away the work already done.

What affects the cost of a custom CRM

CRM development costs vary with the number of user roles and workflows, the integrations involved (WhatsApp, email, accounting, ERP or payment gateways), how much data needs to be migrated, reporting and automation needs, mobile access, hosting and security requirements, timeline and ongoing support.

Because these differ so much between businesses, we don't publish fixed prices or packages. After a scoping call, we send a written proposal with the scope, deliverables and a customised quotation.

Before you talk to us

Frequently asked questions

What is custom CRM development?

Custom CRM development means designing and building CRM software specifically for your business, around your sales process, data and integrations, rather than configuring a general-purpose CRM product.

Is a custom CRM better than Zoho or Salesforce?

It depends on your process. Off-the-shelf CRMs suit standard processes and are quick to start. A custom CRM is better when your process is distinctive, when you need deep integrations, or when per-user licences become expensive. We'll recommend what fits on a strategy call.

Can you integrate the CRM with WhatsApp?

Yes. We integrate with the WhatsApp Business API so conversations and leads are captured in the CRM, approved message templates can be sent, and messages stay linked to the right contact.

Can you migrate our data from Excel or another CRM?

Yes. We clean, de-duplicate and map your existing data, migrate it in stages with checks, and keep the old system available until your team confirms the new CRM is correct.

Will the CRM work on mobile phones?

Yes. We build CRMs that work well in a mobile browser for field and sales teams, and can add a dedicated mobile app if your process needs offline access or device features.

Can the CRM connect to our accounting or ERP software?

Yes, through the systems' APIs where available. Orders, invoices, customers and payments can be synchronised so data isn't entered twice.

Do we own the CRM software and data?

Yes. The source code, database and hosting accounts are yours. There is no per-user licence fee to us for using your own CRM.

How secure is a custom CRM?

We build role-based access control, audit logs, encrypted connections and regular backups into every CRM, and host it in your own cloud account where possible.

Can you add features to our existing CRM?

Yes. We can audit an existing custom CRM, fix problems, and add features, integrations or reports alongside your team.

Do you build industry-specific CRMs?

Yes. We design the CRM around how your industry sells, for example admissions for education, site visits for real estate, dealer quotations for manufacturing, or client approvals for agencies.

How long does it take to build a custom CRM?

It depends on the scope: roles, workflows, integrations, data migration and reports. We usually deliver the core pipeline first and agree the full timeline in the written proposal.

Do you provide training and support after launch?

Yes. We train your team on their daily workflows and offer ongoing support for fixes, updates and new features.

Are you a Zoho or Salesforce partner?

No. We are an independent development company. We build custom CRMs and also implement and customise Zoho and Odoo for clients who choose those platforms.

How much does custom CRM development cost in India?

It depends on the scope: user roles, workflows, integrations, data migration, reports and support needs. We do not publish fixed prices; share your requirements and we will send a customised quotation after a scoping call.
