OGEN Infosystem is India's full-service ERP implementation agency — providing structured ERP implementation services since 2013. We go from business process mapping through data migration, system configuration, user acceptance testing, and zero-downtime go-live. SAP Business One, Odoo, Microsoft Dynamics 365, Oracle NetSuite, and fully custom ERP — 100% in-house, by a 30+ person team. Fixed-price. No outsourcing.
ERP implementation is the complete, structured process of deploying an Enterprise Resource Planning system inside a business — migrating historical data, configuring modules to match actual workflows, integrating with third-party systems (GST portal, Tally, WhatsApp, payment gateways), training department heads, and going live without disrupting day-to-day operations. A qualified ERP implementation services provider manages every phase of this process, not just the software install.
The failure reasons are always the same: platform selected before operations are understood, data migration complexity under-estimated, user training treated as optional, and implementation partners who optimise for billing speed rather than operational stability. Choosing the right ERP implementation agency — one that starts with discovery, commits to a fixed timeline, and stays accountable through go-live — changes each of these outcomes.
Map every department's workflows, approval chains, and integration dependencies before selecting any platform.
Extract, clean, and validate historical data from Tally, Excel, and legacy systems with three checkpoints.
Connect GST portal, Tally, WhatsApp, Razorpay, and biometric devices as first-class integrations.
Your actual department users test real workflows before go-live — not scripted demos.
Staged cutover with parallel-run support and 30-day hypercare at no extra charge.
As a full-service ERP implementation agency, OGEN handles every major platform — from SAP Business One deployments to Odoo rollouts, Microsoft Dynamics 365, Oracle NetSuite, and fully custom ERP builds. Our ERP implementation services cover the platform that fits your scale, budget, and India compliance requirements.
SAP Business One is purpose-built for growing SMEs and mid-market companies — covering Finance, Inventory, Procurement, Manufacturing, and CRM in a single platform. Our implementation team handles full SAP Business One deployment including India localisation: GST e-invoicing, TDS/TCS, and Tally data migration to SAP.
Odoo is one of the fastest-growing open-source ERP platforms globally — modular, flexible, and available in Community (free) and Enterprise editions. Our Odoo implementation includes India localisation for GST, e-invoicing, and TDS compliance, which are absent from the default Odoo Community build. We implement Odoo for manufacturing, distribution, retail, and services companies.
Microsoft Dynamics 365 Business Central and Finance & Operations cover mid-to-enterprise business management — deeply integrated with Microsoft 365, Power BI, and Teams. Our implementation team handles Business Central deployments for Indian companies, including India tax configuration, approval workflows, and Power BI reporting dashboards.
Oracle NetSuite is a cloud-native ERP built for fast-growing companies and multi-subsidiary organisations — covering Financials, Inventory, CRM, and E-Commerce in a unified platform. Our team handles NetSuite implementations for Indian subsidiaries of global companies, including localisation for GST, multi-currency, and Indian payroll compliance.
Zoho Books, Zoho Inventory, and Zoho One are popular with Indian SMEs for their competitive pricing and deep GST compliance. Our Zoho implementation covers Zoho Books accounting setup, Zoho Inventory for warehouse management, Zoho CRM, and Zoho One integrated deployments — with custom workflows, Tally migration, and staff onboarding.
When no off-the-shelf platform fits your operations without heavy customisation — or when recurring licence costs make long-term ownership expensive — a custom ERP built and implemented by OGEN Infosystem is the answer. We build and implement ERP systems from scratch: Finance, HR, Inventory, Manufacturing, Procurement, GST, WhatsApp, and Tally — fully tailored and fully documented.
The right ERP depends on your scale, budget, and how much your operations deviate from global templates. Here is an honest comparison — no platform bias, no sales agenda.

Since 2013, OGEN Infosystem has been India's most accountable ERP implementation agency — delivering end-to-end ERP implementation services across 8 industries, 100% in-house, zero outsourcing. Here is what separates our ERP implementation services company from every other ERP consultant in India.
Most ERP failures start with a platform that was selected before the business's actual workflows were understood. OGEN runs a structured 5–7 day discovery across every department before recommending SAP, Odoo, Dynamics, or a custom build — so you get the right tool, not the highest-commission one.
Poor data migration is the #1 cause of ERP go-live failure. Our migration team runs structured extraction, cleansing, and validation from Tally, Excel, or legacy systems — with three reconciliation checkpoints before a single record enters the new ERP. Opening balances, vendor masters, stock values, and historical transactions all verified.
ERP projects without a written, committed timeline are ERP projects without accountability. Every OGEN implementation contract includes a milestone schedule with weekly demo deliverables, a UAT period, and a fixed go-live date — before any invoice is raised.
Global ERP platforms treat Indian compliance as an afterthought. Tally integration, GST e-invoicing (IRN generation), WhatsApp Business API approval routing, and UPI/Razorpay payment reconciliation are first-class features in every OGEN ERP implementation — not costly add-on modules from third-party vendors.
The biggest hidden cost in ERP implementation is poor user adoption — teams that go back to Excel because the system feels unfamiliar. OGEN runs module-level training for each department head and administrator, plus screen-recorded guides for common workflows, until your team can operate independently.
As a dedicated ERP implementation agency, we operate on one principle: every milestone is documented, every deliverable is visible, and no go-live happens without your team's written sign-off. This is what professional ERP implementation services look like — not a black box, not a status email once a month.
We interview every department head — Finance, HR, Inventory, Procurement, Manufacturing — and document current workflows, approval chains, compliance obligations, and integration dependencies. This becomes the blueprint for every decision in the implementation. No assumptions, no guesswork.
Based on discovery findings, we recommend the right platform — SAP Business One, Odoo, Dynamics 365, or a custom build. Module scope, database architecture, integration contracts, and access roles are locked in writing before any work begins. No platform is recommended without written justification.
We extract historical data from Tally, Excel, or your current system. Duplicate records are flagged, incomplete GST numbers corrected, opening balances reconciled. Three validation checkpoints confirm stock values, account balances, and vendor/customer masters match your legacy data — to the rupee — before migration proceeds.
Modules configured to your approval chains and compliance rules. Integrations built: GST portal (e-invoicing, e-waybill, GSTR filing), Tally two-way sync, WhatsApp Business API approvals, Razorpay/UPI reconciliation, biometric payroll devices. Weekly live demos — you see the system taking shape, not just a status email.
Your actual department users — not just IT — run real business workflows: a complete purchase cycle, payroll run, month-end GST filing, inventory GRN, and production order. Every screen and approval chain validated by the people who will use it daily. No go-live clearance without user sign-off.
Parallel-run cutover ensures zero operational disruption. Module-level training for every department head. Complete data backup, documentation, and credential handover at delivery. Then 30 days of hypercare — our team on standby to resolve edge cases as real operations run for the first time. Included at no extra charge.
Most ERP implementation services companies quote the implementation fee and hide the rest. This is the complete picture — platform licence, implementation, India localisation add-ons, data migration, training, and post-go-live support costs for every major platform. From a services provider that has assessed 50+ ERP projects since 2013.
Best for: ₹100Cr+ manufacturers with global reporting needs
Best for: SMEs needing modular open-source ERP at lower cost
Best for: Microsoft-ecosystem companies needing Power BI & Teams

Tally is the accounting backbone of 6+ million Indian businesses. Moving off Tally to a modern ERP is the most common implementation engagement our services company handles — and poor Tally data migration is the #1 reason Indian ERP go-lives fail. As a specialist ERP implementation services provider, we have built a structured 3-checkpoint migration process that ensures every ledger, every stock value, every vendor record, and every historical balance carries across exactly — to the rupee.
XML/CSV export from Tally — all masters, ledgers, stock items, and transactions extracted in structured format
Duplicate records merged, incomplete GST numbers corrected, HSN codes validated, opening balances reconciled
Three-round reconciliation — every figure confirmed against Tally closing balances before go-live clearance
We evaluated SAP Business One and Dynamics 365 before speaking with OGEN. Neither fit our specific job-costing workflow without expensive customisation — and neither included India-native GST e-invoicing at a price that made sense. OGEN built and implemented a custom ERP in 5 months. It's been running clean for 18 months without a single escalation.
Rajesh MenonOur Tally data migration was the part we were most worried about — 6 years of accounts, 4,200 product SKUs, and 800 vendor records. OGEN's migration team ran three validation rounds. Every figure reconciled to the rupee. We went live on a Friday. Monday morning, the finance team processed the first purchase order and payment without any issues. That's what a proper implementation looks like.
Priya KapoorWe were on Odoo Community and struggling with Indian GST compliance — the community modules were unreliable and our Tally accountant couldn't work with Odoo's output. OGEN moved us to their custom ERP in 14 weeks. WhatsApp approval routing for purchase orders was something we didn't even know was possible. Our procurement manager approved three POs from his phone while travelling to Bangalore. Genuinely changed how we operate.
Suresh NambiarTalk directly with our ERP implementation services team — a dedicated agency in operation since 2013 across 8 industries. They'll assess your operations and send a fixed-price ERP implementation quote within 48 hours. No obligation, no sales pitch — just an honest platform recommendation backed by 13 years of delivery experience.
We review your operations, headcount, turnover, and compliance requirements — then tell you honestly whether SAP, Odoo, Dynamics, or a custom ERP is the right fit. We don't recommend the most expensive option. We recommend the one that works for your business.
After the call, you receive a detailed scope document with a module-by-module fixed price, delivery timeline, data migration assessment, and integration requirements — before any commitment.
If a custom ERP isn't the right fit for where you are today, we'll say so — we only take on projects where we're confident we can deliver results.
ERP implementation is the end-to-end process of deploying an Enterprise Resource Planning system inside a business — from initial business process analysis and platform selection through data migration, system configuration, user acceptance testing, staff training, and go-live. It is not just installing software. A proper implementation changes how every department — Finance, HR, Inventory, Procurement, Manufacturing — records, approves, and reports on their operations.
A successful ERP implementation has five non-negotiable phases: business process analysis (what does your business actually do, and how?), data migration and cleansing (moving accurate historical data from Tally or Excel into the new system), system configuration (mapping your approval chains and compliance rules into the ERP), user acceptance testing (your team validates real workflows before go-live), and hypercare support (30–90 days of intensive post-launch support). Skip any of these and the project typically fails.
