Off the shelf CRMs like HubSpot and Salesforce are built for every business, which means they fit no business perfectly. Your sales process has stages, fields, and workflows that do not map to their templates. We build CRMs that match exactly how your team sells — with the fields you use, the automations you need, and none of the features that slow your reps down.

CUSTOM CRM— 28+ CRM SYSTEMS DELIVERED
Marketing Wise

A CRM your sales team willWe build custom CRM systems for clients based in Noida, Delhi & NCR, India

Marketing Wise has delivered 28+ custom CRM systems for businesses across Noida, Delhi, and Gurugram — B2B sales CRMs for manufacturing and distribution companies, real estate CRMs with property and inventory management, service CRMs for agencies and consultancies, and field sales CRMs for teams operating across multiple territories. Each is built around the actual sales motion of the business, not a generic SaaS template.

The most common reason businesses build a custom CRM is that they have tried HubSpot, Zoho, or Salesforce and found that adapting their sales process to the tool costs more in productivity than the tool saves in organisation. A custom CRM gives you the exact pipeline stages, custom fields, automation rules, and reporting views your team needs — built once, owned permanently, with no per-seat subscription that scales with your headcount.

  • Custom lead pipeline with configurable stages and fields
  • Follow-up automation with WhatsApp, email, and SMS reminders
  • Quote and proposal generation with approval workflows
  • Customer 360 view — full interaction history, documents, and notes
  • Sales forecasting and team performance reporting
  • Mobile-responsive interface for field sales teams
Why build a custom CRM instead of using HubSpot, Zoho, or Salesforce?
Off-the-shelf CRMs work well when your sales process is standard. When your process has non-standard stages, complex product configurations, custom approval workflows, or industry-specific fields, you end up spending more time working around the CRM than using it. A custom CRM is built once, owned outright, costs nothing per seat, and does exactly what your process requires.
Can the custom CRM integrate with WhatsApp for follow-up communication?
Yes. We integrate the WhatsApp Business API into the CRM so sales reps can send follow-up messages, share quotes, and receive customer replies without leaving the CRM interface. Message history is stored against the lead. Automated follow-up sequences can send WhatsApp messages at defined intervals after specific pipeline events.
Can the CRM handle lead distribution across a large sales team?
Yes. We build lead assignment rules — round-robin, territory-based, product-based, or capacity-based — that automatically assign new leads to the right rep. Re-assignment rules handle leads that have not been contacted within a set time. Managers see assignment queues and can override manually.
Can you build a CRM that works for field sales teams on mobile?
Yes. We build mobile-responsive CRMs that field reps use on their phones — log a meeting, update a lead status, upload a visit photo, or record a voice note from the field. For offline-heavy scenarios, we build progressive web apps with local storage that sync when connectivity is restored.
Can the CRM generate quotes and proposals automatically?
Yes. We build quote generation modules where a rep selects products or services, applies pricing rules, generates a formatted PDF quote, and sends it directly to the customer via email or WhatsApp from within the CRM. Approval workflows route quotes above a threshold amount to a manager before sending.
Can the CRM connect to our existing ERP or accounting software?
Yes. We integrate custom CRMs with Tally, SAP, Zoho Books, and custom ERP systems — won deals in the CRM push customer and order records to the ERP automatically. This eliminates manual re-entry and ensures the operations team has the right information the moment a deal closes.
How do you handle duplicate leads from multiple sources?
We build deduplication logic that checks for matching phone numbers, email addresses, or company names when a new lead arrives. Duplicates are flagged for review or automatically merged with the existing record. Source tracking is preserved so you know which channel generated the original lead.
Can the CRM track leads from our website, ads, and other sources automatically?
Yes. We build lead capture integrations that pull leads from your website contact form, Facebook Lead Ads, Google Ads lead forms, IndiaMart, and other sources directly into the CRM — no manual copy-paste. Each lead is tagged with its source so you can report on conversion by channel.
What reporting does a custom CRM include?
We build the reports your management team actually reviews: pipeline stage distribution, lead-to-deal conversion rate by source and rep, average deal value by product, follow-up compliance rate, daily activity summary (calls, meetings, messages), and sales forecast based on pipeline value and historical close rates.
How long does a custom CRM take to build and what does it cost?
A core CRM with lead management, pipeline, follow-up automation, and basic reporting takes 10–14 weeks. Full-featured CRMs with quote generation, ERP integration, mobile apps, and advanced forecasting take 16–20 weeks. Pricing starts at ₹8 lakhs for a focused build.

Step by stepStep by step

Our process

No mystery phases. Four gates every custom CRM engagement crosses — from sales process mapping to team go-live.

Sales process mapping & CRM design

We run a discovery session with your sales team and management to map every stage of your sales process, identify the custom fields needed, define lead sources and assignment rules, and document the follow-up sequences. The CRM is designed around what we find — not a generic template.

Week 1–2

Core CRM build — pipeline, leads, users

Lead management, pipeline stages, custom fields, user roles, and the basic interaction log are built and deployed to staging. Your sales manager reviews the core workflow against real leads before we proceed to automation and integrations.

Week 3–7

Automation, integrations & reporting

Follow-up automations, lead source integrations (website, portals, ad platforms), WhatsApp integration, quote generation, ERP connector, and reporting dashboards are built. A pilot group of 3–5 reps uses the CRM with real leads and provides feedback before full rollout.

Week 8–14

Team training, data migration & go-live

Historical lead data is migrated from Excel or the previous CRM. The full team is trained in a 2-hour session with recorded walkthroughs left for future onboarding. The CRM goes live with a 30-day hypercare period where we fix anything the team identifies in real use.

Exit
Our Diverse Development SolutionsOur Diverse Development SolutionsSince 2014
[01]Custom Web Applications
We architect and build bespoke web applications from first principles — SaaS platforms, multi-role operational dashboards, customer and vendor portals, ERP systems, booking engines, and data-intensive workflow tools. Every system is designed around your exact business logic and data model, not a template. Stack: React / Next.js frontend, Node.js or Python backend, PostgreSQL or MongoDB, deployed on AWS or GCP with CI/CD from day one.
[02]API & System Integrations
We design and implement secure, production-grade integration layers that connect your new application to your existing stack. Tally ERP, Salesforce CRM, Razorpay, WhatsApp Business API, Shiprocket, Google Workspace, Zoho, SAP — if it exposes a REST or GraphQL endpoint, we wire it in. We build middleware layers, webhook handlers, and real-time sync pipelines so your data flows without double entry or manual reconciliation.
[03]Cloud & DevOps Engineering
We provision, configure and manage right-sized cloud infrastructure on AWS, GCP or Azure — auto-scaling groups, managed databases (RDS, Cloud SQL, Atlas), CDN delivery, container orchestration with Docker and Kubernetes, and CI/CD pipelines via GitHub Actions or GitLab CI. Every environment ships with uptime monitoring, alerting, automated backups and a documented runbook. We target 99.9%+ uptime SLAs as a baseline, not a premium.
[04]Mobile & Cross-Platform Apps
We build React Native and Flutter applications that share the same backend APIs as your web platform — giving you iOS, Android and web coverage from a single, unified codebase. Features include offline support with local data sync, push notifications, biometric authentication, payment gateway integration, and submission to both the App Store and Google Play. One deployment pipeline, consistent data across every device.
[05]AI & Intelligent Automation
We build production-grade AI-powered applications: RAG pipelines over private document corpora, LLM-integrated workflow tools using the OpenAI and Anthropic APIs, agentic orchestration layers using MCP and n8n, and intelligent data extraction and classification systems. We do not bolt AI onto existing apps as a feature — we architect it as a core system component with proper context management, fallback logic, audit trails and cost controls.
[06]Legacy Modernisation & Audits
We take over underperforming, insecure or unmaintainable codebases and make them production-safe. Our audit process covers code quality, OWASP security vulnerabilities, performance bottlenecks, dependency staleness, database schema health and infrastructure risk. From there we stabilise, refactor and migrate — moving monoliths to modular architectures, upgrading stacks, replacing brittle third-party dependencies and restoring test coverage — so the codebase is ready for new features without accumulating further technical debt.
CASE STUDIES

Custom CRM systems we have built
for businesses in Noida & Delhi NCR

01Manufacturing & Distribution

Custom B2B sales CRM for a Noida industrial equipment manufacturer with a 45-rep sales team

Lead follow-up compliance rate improved from 41% to 89%. Pipeline visibility allowed management to forecast revenue within 8% accuracy for the first time.

Problem

The team managed leads in Excel shared over email — no visibility into pipeline stage, no follow-up reminders, no reporting. Deals were being lost because leads were not followed up and managers had no way to see where each rep's pipeline stood.

Solution

We built a custom CRM with territory-based lead assignment, configurable pipeline stages matching the company's actual sales cycle (initial contact → demo → technical evaluation → commercial negotiation → PO), WhatsApp follow-up automation, and a management dashboard with real-time pipeline visibility.

Stack

React, Node.js, PostgreSQL, WhatsApp Business API, Redis, Resend

02Real Estate

Property sales CRM for a Delhi NCR real estate developer managing 3 active projects

Lead-to-site-visit conversion improved from 18% to 34%. Sales team headcount reduced by 2 while overall bookings increased 22%.

Problem

The developer was managing leads from portals (99acres, MagicBricks, Housing.com), walk-ins, and referrals across 3 projects in three separate Excel sheets. Leads were duplicated, follow-up was inconsistent, and there was no system to track which unit each prospect was interested in.

Solution

We built a real estate CRM with unified lead capture from all portals via API, unit inventory management (floor plans, prices, availability), interest tracking per unit, site visit scheduling, and automated WhatsApp follow-up sequences calibrated to the typical 45-day decision window.

Stack

React, Node.js, PostgreSQL, 99acres/MagicBricks API, WhatsApp Business API, AWS S3

03Professional Services

Agency CRM with proposal management for a Gurugram digital marketing agency group

Proposal turnaround time reduced from 4 days to 6 hours. Deal close rate improved 19% after pipeline visibility identified the stage at which deals were stalling.

Problem

The agency managed new business in email threads and a shared Google Sheet. Proposals were built in PowerPoint, sent by email, and follow-up depended on individual account managers remembering. There was no way to see the full pipeline or identify where deals were being lost.

Solution

We built an agency CRM with a 6-stage pipeline, proposal builder that generates branded PDFs from service templates, e-signature integration, automated follow-up sequences, and a management dashboard showing pipeline stage conversion rates and rep performance.

Stack

React, Node.js, PostgreSQL, PDF generation (Puppeteer), DocuSign API, SendGrid, Resend

Custom Web App Development — Marketing Wise Noida

Top Rated Full StackSoftware Developers
in Noida, Delhi, NCR & India

Custom CRM system development for B2B sales teams, real estate, and service businesses in Noida and Delhi NCR.

Marketing Wise builds custom CRM systems for businesses in Noida and Delhi NCR — lead pipelines, follow-up automation, quote generation, WhatsApp integration, ERP sync, and sales reporting built around your actual sales process. No per-seat subscription. Twenty-eight CRM systems delivered since 2020.

How much does custom CRM development cost in India?

A focused CRM with lead management, pipeline, follow-up automation, and reporting starts at ₹8 lakhs. Full-featured CRMs with quote generation, ERP integration, mobile field app, and advanced analytics range from ₹14–25 lakhs depending on team size and process complexity.

How long does it take to build a custom CRM?

A core CRM with pipeline, lead assignment, follow-up automation, and basic reporting takes 10–14 weeks. Full builds with quote generation, ERP integration, and mobile interface take 16–20 weeks. Timeline is heavily influenced by the number of lead sources to integrate and the complexity of approval workflows.

Can a custom CRM replace HubSpot or Zoho for our team?

For most businesses, yes — a custom CRM replaces the core functionality your team actually uses (pipeline management, follow-up tracking, reporting) without the features no one touches and without per-seat pricing. The break-even vs HubSpot Professional is typically 18–30 months at 20+ seats.

Can the CRM capture leads from IndiaMart, 99acres, and other portals automatically?

Yes. We integrate with IndiaMart, 99acres, MagicBricks, Housing.com, Facebook Lead Ads, Google Lead Forms, and your website contact form — all leads flow into the CRM automatically, tagged by source, with no manual copy-paste.

Can the CRM send automated WhatsApp follow-ups to leads?

Yes. We integrate the WhatsApp Business API for automated follow-up sequences — a welcome message on lead creation, a follow-up on day 2, a check-in on day 7, and a re-engagement on day 30. Each message uses pre-approved templates and can be personalised with the lead's name, product interest, and rep's contact details.

Fixed-price contracts for clearly scoped work — line-item quote broken down by module, not a lump sum. Monthly retainers for ongoing product development.
