Why off-the-shelf ERP does not fit your business
If you have evaluated NetSuite, SAP, Odoo or Microsoft Dynamics in the last three years, you already know the four problems below. Custom ERP development used to mean a six-figure dev shop quote and a 12-month timeline. AI changes the math.
Enterprise ERP: $50K-$500K + 6-12 month implementation
NetSuite SuiteSuccess starts at $30,000 per year for licences and another $50,000 to $250,000 for the partner-led implementation. SAP Business One runs $15,000 to $75,000 in licences plus a partner SOW. You write the cheque before you have working software.
The Odoo per-module + partner trap
Odoo's marketing price is per app per user per month. The real cost is 3 to 5x that once a partner has billed for implementation, customisation, training and the modules you actually need (manufacturing, accounting localisation, inventory advanced). Free in name, six figures in practice.
Off-shelf ERPs force you to change your processes
Every off-the-shelf ERP has an opinion: a fixed PO approval flow, a fixed BOM data model, a fixed GL chart structure. If your business runs a different way, you bend your team to fit the tool, or you pay the partner to customise it (and then live with the upgrade pain forever).
In-house dev: $80K-$300K, 9-18 months to v1
A traditional ERP development company quotes $80,000 to $300,000 and takes 9 to 18 months. Most of that is senior engineering time on the work that is the same across every ERP: auth, roles, masters, transaction tables, audit logs, dashboards. You pay senior rates for commodity code.
AI does the 90% that is the same across every ERP. We do the 10% specific to your operations. That is how custom ERP software costs a fraction of agency price.
Auth, roles, item masters, vendor masters, customer masters, GL postings, transaction tables, list and detail pages, dashboards, audit logs: identical across every ERP. AI ships them in hours. A Fuzen delivery engineer focuses entirely on the parts that are different about how your operations actually run.
What we build into your ERP
Eight building blocks of a complete custom ERP. Mix and match for the scope that fits your business.
Inventory + warehouse
Item masters, multi-warehouse, batch and lot tracking, FIFO and FEFO costing, barcode and bin tracking, cycle counts, GRN and dispatch flows. The inventory model your operations actually run.
Finance, accounting + GST
Custom chart of accounts, GL postings from every transaction, AR and AP, bank reconciliation, India GST invoices and returns, e-invoice and IRN, multi-currency, financial statements that match your auditor.
Procurement + vendors
Vendor masters, RFQ and quote comparison, PO approval workflows by amount and category, GRN, vendor invoice matching, vendor performance dashboards. The procurement controls your CFO actually wants.
Production + service ops
Multi-level BOM, work orders, routing and operations, shop-floor entries, sub-contracting, scrap and rework, service-job tracking for non-manufacturers. The production model your plant actually runs.
HR + payroll
Employee masters, attendance and shifts, leave, payroll with India statutory (PF, ESI, PT, TDS), expense claims, performance reviews. Tightly integrated with finance so payroll posts to GL automatically.
Sales + CRM
Customer masters, leads and pipeline, quotes, sales orders, dispatch, invoicing and AR ageing. Same data model as your CRM, with sales orders flowing straight into your inventory and GL.
Reports + dashboards
Stock ageing, gross-margin by SKU, plant utilisation, AR ageing, vendor spend analysis, plant vs branch P&L, MIS for board meetings. The reports your CFO and ops head review every Monday.
Multi-entity + multi-location
Multiple legal entities, multiple GST registrations, multiple plants and warehouses, inter-branch transfers, consolidated financials, eliminations and inter-company reconciliation.
