Choosing and implementing the right ERP, not just installing one

An ERP system puts accounting, inventory, purchasing, sales, payroll and production on one database, so a sales order updates stock, triggers procurement and posts to the ledger without anyone re-typing it. Open-source platforms like Odoo and ERPNext now give growing companies most of what large ERPs offer, at a fraction of the licence cost, while custom ERP fits businesses with truly unusual processes.

Our ERP solutions practice suits manufacturers, distributors, traders, retailers and service firms that run on Tally plus spreadsheets and have hit the limit: stock numbers nobody trusts, purchase approvals over WhatsApp, payroll in Excel and month-end reports that take a week. Indian businesses also need GST returns, e-invoicing and e-way bills handled inside the system.

Nexzem starts with a fit-gap study against Odoo, ERPNext and a custom build, and recommends the option with the least customisation that still matches your process. We configure modules, migrate masters and opening balances, connect Tally where accounts stay there, and roll out department by department. If you already run an ageing ERP, our ERP modernization service covers that path instead.

Where ERP Solutions fits

5 recipes

  • Manufacturer moving beyond Tally and spreadsheets

    A growing manufacturer replaces disconnected spreadsheets with an ERP covering purchasing, inventory, production planning, sales and GST accounting, integrated with Tally during transition, giving management a reliable daily view of stock and orders.

  • Multi-branch distributor

    A distributor with several branches centralizes stock, pricing, credit limits and collections in one ERP, with branch-level reporting and inter-branch transfers, ending the monthly reconciliation problems caused by separate local systems at each branch.

  • Project accounting for a services firm

    An engineering services company tracks project budgets, timesheets, purchases and billing milestones in its ERP, giving managers real-time profitability by project and reducing the month-end closing effort for the accounts team.

  • Batch traceability for a food processor

    A food processing company records raw material batches through production to finished goods and customer dispatches, enabling quick traceability for quality issues and recalls while meeting buyer and regulatory documentation requirements.

  • Retail chain back office

    A retail chain connects store point-of-sale systems with a central ERP for purchasing, replenishment, transfers and accounting, giving head office accurate sales and stock data across all stores every day.

ERP Solutions, in depth

  1. P1

    Why ERP implementations fail

    ERP projects have a reputation for delays and overruns, and the causes are usually organizational rather than technical. The most common is unclear processes. If the business has not agreed how purchasing, inventory or billing should work, the ERP becomes the place where those disagreements surface, slowing every configuration decision.

    Heavy customization is the second major cause. Trying to make a standard ERP replicate every habit of the old system creates complex code that is expensive to maintain and difficult to upgrade. Adapting processes to the ERP's standard approach wherever reasonable usually produces better long-term results.

    Weak data preparation causes painful go-lives. Duplicate customers, inconsistent item codes and incorrect opening balances undermine trust in the new system from the first day. Data cleansing deserves its own plan, owners and timeline rather than being treated as a final technical task. Finally, many projects underinvest in people. Key users must be released from daily work to participate in design and testing, and leadership must actively support the change. Projects staffed only by the implementation partner rarely succeed.

  2. P2

    Preparing data for ERP migration

    Data migration is one of the most underestimated parts of an ERP project. Records from Tally, spreadsheets or older systems rarely match the structure the new ERP expects, and errors become visible immediately in invoices, stock levels and financial reports. A disciplined approach covers the steps below.

    Decide early what to migrate. Many companies move only open transactions and opening balances, keeping historical details in an archive or the old system for reference. Migrating years of history adds effort and risk with limited benefit for daily operations.

    Assign business owners to each data area, such as finance for opening balances and stores for item masters. Technical teams can transform data, but only business owners can confirm it is correct. Run at least two trial migrations before go-live. Each trial reveals mapping errors and data quality issues that can be fixed before the final cutover, when time is short and pressure is high.

    • Clean and deduplicate customers, suppliers and items.
    • Standardize units, tax codes and item categories.
    • Agree opening balances with finance and auditors.
    • Migrate open orders, invoices and stock positions.
    • Reconcile migrated data against the old system.
  3. P3

    Change management and training

    An ERP changes how almost everyone in the company works, from purchase clerks to the finance head. People used to familiar spreadsheets or older software may resist new screens and stricter controls, especially if they were not consulted during design. Explaining why the change matters builds support.

    Train by role, using the company's own data and scenarios. A store keeper needs to know receiving, issues and stock transfers, not the full financial module. Short sessions close to go-live, followed by quick reference guides and floor support in the first weeks, work better than long classroom training months earlier.

    Key users, sometimes called super users, are essential. They help design processes, test the system and support colleagues after launch, reducing dependence on external consultants and spreading knowledge throughout the organization. Plan hypercare after go-live. The first month typically brings questions, small configuration changes and process adjustments. Daily check-ins and a clear issue log help resolve problems quickly and build confidence in the new system.

ERP Solutions FAQs

Something else on your mind? Ask a consultant and get a reply within one business day.

Should we choose Odoo, ERPNext or a custom ERP?

Odoo has the widest app ecosystem and a polished interface. ERPNext is fully open source with strong manufacturing and accounting features. Custom ERP makes sense only when your core process is unusual enough that a package would need heavy changes. Our fit-gap study compares all three against your actual workflows.

What does an ERP implementation cost?

Cost depends on the number of modules and users, the amount of customisation, data migration volume, integrations such as Tally, ecommerce or banks, and training needs. Odoo Enterprise also carries its own per-user licence fees. A fixed quote follows the free consultation and fit-gap study.

Can we keep using Tally for accounts?

Yes. Many clients run operations in the ERP and keep statutory books in Tally. We set up a sync for sales, purchase vouchers, ledgers and stock so your accountant does not re-enter anything.

How long does ERP implementation take?

A small trading company on standard modules can go live in 6-10 weeks. A manufacturer with several plants, custom workflows and integrations usually needs 4-8 months, rolled out in phases.

Is our business data safe?

We sign an NDA on request, host on servers you own or control, enforce role-based access, enable audit logs and set up automated daily backups. You keep full ownership of data and any custom code.

Do you provide support after go-live?

Yes. Monthly support plans cover user queries, bug fixes, new reports, version upgrades and small changes as your process evolves.

Can the ERP handle GST e-invoicing and e-way bills?

Yes. ERPs such as Odoo and ERPNext support Indian GST localization, and e-invoicing and e-way bill generation can be integrated with government systems through authorized service providers. We configure tax rules, document formats and integrations, and test them with your finance team before go-live.

Can we start with a few modules and add more later?

Yes, and it often reduces risk. Many companies begin with finance, purchasing, inventory and sales, then add manufacturing, HR, projects or service modules once the core is stable. Planning the overall design upfront ensures later modules fit without rework.

Do you train our staff on the new ERP?

Yes. Training is role-based and uses your own data and scenarios. We train key users in depth so they can support colleagues, run shorter sessions for other staff, and provide guides and floor support during the first weeks after go-live.
