SAP and Oracle are built for global enterprises with global budgets and global IT teams. Tally manages your accounts but not your operations. The gap between what off-the-shelf software does and what your business actually needs is where efficiency is lost. A custom ERP closes that gap — every module built for your process, integrated from day one.

CUSTOM ERP— 18+ ERP SYSTEMS DELIVERED
Marketing Wise

One system for every operation —We build custom ERP systems for clients based in Noida, Delhi & NCR, India

Marketing Wise has delivered 18+ custom ERP systems for manufacturers, distributors, trading companies, and service businesses across Noida, Delhi, and Gurugram. Each system is built module by module — starting with the operations that generate the most manual work and adding modules as the business adopts the platform. We do not sell a pre-built ERP and configure it to fit; we build from the schema up around your actual workflows.

A custom ERP built for your business gives you things no off-the-shelf system can: approval workflows that match your authority matrix, reports that show your KPIs (not generic accounting metrics), integrations with the specific tools your industry uses, and a UI your team can navigate without weeks of training. The total cost of ownership over 5 years is typically lower than per-seat licensing for enterprise ERP, with a system that actually reflects how you operate.

  • Procurement and purchase order management
  • Inventory management with multi-location and batch tracking
  • Production planning and shop floor control
  • Sales order management and dispatch tracking
  • Finance — accounts payable, receivable, and P&L reporting
  • HR, payroll, and attendance management
When does it make sense to build a custom ERP instead of buying SAP or Odoo?
Build custom when your process has non-standard requirements that force expensive SAP customisation, when per-seat licensing at your team size makes commercial ERP uneconomical, or when you have tried an off-the-shelf ERP and found that making your team work around it costs more than it saves. If a standard ERP fits, we will tell you — we do not recommend custom builds when a configurable product will do the job.
Can you build the ERP module by module so we do not have to change everything at once?
Yes. This is how we always approach ERP builds. We start with the 1–2 modules that solve the most acute pain — usually inventory and procurement, or production and dispatch — deploy them, get the team using them, then add modules in subsequent phases. A big-bang ERP replacement is high-risk; a phased module rollout lets the team adapt and gives you working software quickly.
Can the custom ERP integrate with Tally for accounting?
Yes. Most of our ERP builds keep Tally as the accounting system — it is cost-effective, widely understood by Indian finance teams, and does not need replacing. We build a Tally integration layer that pushes sales invoices, purchase orders, payments, and journal entries from the ERP into Tally automatically, so the accounts team works in Tally while operations teams work in the custom ERP.
Can the ERP handle multi-location inventory across warehouses and branches?
Yes. We build inventory modules with multi-location stock tracking — stock levels per warehouse, inter-location transfer requests and approvals, location-specific reorder points, and consolidated stock reporting across all locations. Batch and serial number tracking are supported for regulated industries.
Can you build production planning and shop floor management into the ERP?
Yes. We build production modules with bill of materials (BOM) management, production order creation from sales orders, shop floor job cards, machine and labour time tracking, raw material consumption recording, and finished goods quality inspection before stock update.
How do you handle user roles and approval workflows in a large organisation?
We build role-based access control where each user role sees only the modules and data relevant to their function. Approval workflows are configured to your authority matrix — a purchase order above ₹5L requires the VP Finance, below requires the department manager. Workflows are configurable without code changes.
Can the ERP generate the reports our management team actually wants?
Yes. We build the specific reports your management reviews — gross margin by product or customer, inventory ageing, purchase price variance, production efficiency, debtor ageing, and cash flow projection. These are not generic accounting reports; they are built from your data model to show the KPIs your business actually tracks.
How do you migrate data from our current Excel files or legacy system into the new ERP?
We build data migration scripts that import historical data — customer master, vendor master, product catalogue, opening stock, and outstanding transactions — from Excel or your existing system into the new ERP. Data is validated before import, and the migration is run in a staging environment first so the team can verify accuracy before going live.
How long does an ERP implementation take and how disruptive is the transition?
A focused 3-module ERP (procurement, inventory, sales) takes 20–28 weeks. A full-featured ERP covering all business functions takes 32–42 weeks. We use a phased rollout to minimise disruption — the old system runs in parallel until the new one is stable, and we roll out department by department rather than switching everything on the same day.
What does ongoing support look like after the ERP goes live?
We offer post-go-live support retainers that cover bug fixes, performance tuning, new report requests, workflow adjustments as your process evolves, and new module additions. ERP systems typically require more post-launch support than simpler applications because business processes change and the system needs to reflect those changes.

Step by stepStep by step

Our process

No mystery phases. Four gates every ERP engagement crosses — from process mapping to full-team go-live.

Operations audit & module prioritisation

We run structured sessions with every department head to document current workflows, identify where manual work and data errors concentrate, and prioritise modules by business impact. The build sequence and phased rollout plan are agreed before development begins.

Week 1–2

Phase 1 modules — build & pilot

The highest-priority 2–3 modules are built sprint by sprint. A pilot team from each department tests each module with real data before sign-off. Tally integration and data migration from existing Excel files are completed in this phase.

Week 3–16

Phase 2+ modules & full-team rollout

Remaining modules are added in subsequent phases. Full-team training is delivered department by department. The old system runs in parallel until each department signs off on the new one. Management reporting dashboards are built and validated against known figures before the parallel run ends.

Week 17–32

Go-live, stabilisation & hypercare

The system goes live with a 60-day hypercare period — daily check-ins with department leads, rapid bug fixing, and report adjustments based on real use. Performance is monitored and database queries are tuned once real data volumes are present. A support retainer is agreed for ongoing changes.

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 ERP systems we have built
for businesses in Noida & Delhi NCR

01Manufacturing

Custom ERP for a Noida auto components manufacturer replacing 11 disconnected Excel trackers

Production planning cycle reduced from 3 days to 4 hours. Inventory discrepancy between physical count and records eliminated. On-time delivery improved from 67% to 91%.

Problem

The manufacturer was running procurement, production, dispatch, and quality across 11 Excel files shared on a network drive. Data was inconsistent between files, stock counts were unreliable, and production planning took 3 days of manual consolidation at the start of each week.

Solution

We built a custom ERP covering procurement with vendor price comparison, inventory with batch tracking and multi-store locations, production with BOM-driven job cards, quality inspection with defect logging, and dispatch with customer-linked delivery challans. Tally integration pushed invoices automatically.

Stack

React, Node.js, PostgreSQL, Redis, Tally XML API, AWS S3, BullMQ

02Distribution

Distribution ERP for a Delhi NCR FMCG distributor managing 800 SKUs across 5 warehouses

Order fulfilment accuracy improved from 88% to 99.4%. Stock-out incidents reduced by 74%. Debtor collection cycle shortened by 11 days on average.

Problem

The distributor managed stock across 5 warehouses using Tally for accounting and Excel for operations. Stock transfers between warehouses were tracked in WhatsApp messages. Salespeople did not know real-time stock availability when taking orders, resulting in frequent fulfilment failures.

Solution

We built a distribution ERP with real-time multi-warehouse inventory, mobile order entry for field salespeople with live stock visibility, automatic purchase order suggestion based on reorder levels, route-based dispatch planning, and a collections dashboard showing outstanding by customer with ageing.

Stack

React, React Native (mobile), Node.js, PostgreSQL, Tally API, Redis, AWS S3

03Services

Operations ERP for a Gurugram facility management company managing 120 client sites

Client billing disputes reduced by 83%. Resource utilisation visibility enabled redeployment of 12 FTEs without new hires. Contract renewal rate improved from 71% to 88%.

Problem

The company managed 120 client sites with staff deployment, material consumption, attendance, and billing tracked across separate systems and spreadsheets. Billing was based on manual headcounts that were frequently disputed by clients, and there was no way to see utilisation across sites.

Solution

We built an operations ERP with site and client management, daily attendance marking by site supervisors via mobile, material request and consumption tracking, automated billing based on actual attendance records (eliminating disputes), and a management dashboard showing utilisation, billing, and contract status across all 120 sites.

Stack

React, React Native (supervisor mobile app), Node.js, PostgreSQL, AWS S3, SendGrid

Custom Web App Development — Marketing Wise Noida

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

Custom ERP system development for manufacturers, distributors, and service businesses in Noida and Delhi NCR.

Marketing Wise builds custom ERP systems for businesses in Noida and Delhi NCR — procurement, inventory, production, sales, finance, and HR unified in one system built around your actual operations. We integrate with Tally for accounting and deploy module by module to minimise transition risk. Eighteen ERP systems delivered since 2020.

How much does custom ERP development cost in India?

A focused 3-module ERP (typically procurement, inventory, and sales or production) starts at ₹20 lakhs. Full-featured ERP covering all business functions — procurement, production, inventory, sales, finance, and HR — typically ranges from ₹35–65 lakhs depending on complexity and number of integrations.

How long does custom ERP development take?

A focused 3-module ERP takes 20–28 weeks. A full-function ERP takes 32–42 weeks delivered in phases. We always recommend a phased approach — starting with the 2–3 modules that solve the most pain, deploying them, and adding modules once the team is using the core system.

Can a custom ERP integrate with Tally for accounting?

Yes. We build Tally integration layers that push invoices, purchase orders, payments, and journal entries from the custom ERP into Tally automatically. Most of our clients keep Tally as their accounting system — it is cost-effective, familiar to Indian finance teams, and does not need replacing.

Is a custom ERP cheaper than SAP or Oracle in the long run?

For most Indian SMEs and mid-market companies, yes. SAP Business One starts at ₹3–8L per year in licensing alone, plus implementation and customisation costs. A custom ERP has a one-time build cost and no per-seat or annual license fees. At 20+ users over 4–5 years, the total cost of ownership typically favours custom.

Can the ERP handle GST compliance and Indian tax requirements?

Yes. We build GST-compliant invoicing (CGST, SGST, IGST, cess), HSN code management, e-invoice generation (IRN/QR), e-way bill integration, and GSTR-1/GSTR-3B data export. Tally integration ensures the accounting system reflects the same tax data as the operational system.

No licensing fees post-delivery. No SaaS lock-in — client can deploy, extend or hand to any other team after handover. Mutual NDA signed before any discovery call — business logic, workflows, data structures and competitive information are kept confidential throughout and after engagement. Fixed-price contracts for clearly scoped work — line-item quote broken down by module, not a lump sum. Monthly retainers for ongoing product development.
