# Custom manufacturing ERP development > A manufacturing ERP connects sales orders, purchasing, bills of materials, production, stores, quality, dispatch and accounting in one system. Infikey builds custom ERPs for manufacturers whose processes do not fit packaged products, often keeping Tally or SAP for accounts. Phased builds typically cost USD 60,000–150,000. An ERP shaped around your products, routings and approvals, delivered in phases so the plant keeps running while you switch. - **Budget:** USD 60k–150k+ (INR 50 lakh–1.25 crore+) - **Licences:** No per-user fees - **Accounts:** Sync with Tally, Zoho, QuickBooks or SAP ## ERP modules | Module | What it covers | |---|---| | Sales | Enquiries, quotations, sales orders, delivery schedules, customer pricing | | Engineering | Multi-level BOMs, routings, revisions, drawings and specifications | | Purchase | Indents, supplier quotes, purchase orders, approvals, supplier rating | | Stores | GRN, inspection, bin locations, batch and serial tracking, issues to production | | Production | Work orders, job cards, material consumption, scrap and rework, subcontracting | | Quality | Incoming, in-process and final inspection, NCR and CAPA | | Dispatch | Packing lists, invoices, e-way bills or delivery notes, transporter details | | Analytics | Order status, costing per job, stock ageing, on-time delivery | ## Why manufacturers choose custom over packaged ERP - **Unusual processes**: job-shop work, make-to-order with engineering changes, subcontracting loops or mixed discrete and process production. - **Adoption**: screens match your forms and terms, so the team uses the system instead of working around it. - **Cost at scale**: no per-user licence fees as you add shop-floor users. - **Ownership**: you own the code and the data, and can change workflows without waiting for a vendor roadmap. Packaged ERPs such as Odoo or SAP Business One are often the right answer for standard processes. Our [Odoo vs custom ERP comparison](https://infikeytechnologies.com/compare/odoo-vs-custom-erp) helps you decide honestly. ## Phased delivery plan | Phase | Scope | |---|---| | 1 | Masters, sales, purchase, stores and dispatch | | 2 | BOMs, work orders, production tracking and costing | | 3 | Quality, maintenance, dashboards and dealer portal | Each phase goes live before the next begins. Pair it with [production planning software](https://infikeytechnologies.com/industries/manufacturing/production-planning-software) for finite scheduling. ## Project blueprint: Custom ERP for an auto components supplier Based on the requirements we hear most often from buyers like this. An auto components supplier makes parts to order for several OEMs. Sales schedules, BOM revisions, subcontracting and quality records live in separate spreadsheets alongside Tally, so delivery dates are guesses and traceability for audits is painful. What we would build: - Sales schedules from OEMs with delivery planning - Multi-level BOMs with revision control - Purchase, stores and subcontracting with job work challans - Production work orders with material issue and scrap tracking - Incoming and final inspection records with batch traceability, synced with Tally How success is measured: - On-time delivery to OEM schedules - Inventory value and stock accuracy - Time to trace a batch for a customer complaint - Cost per part against standard ## Frequently asked questions ### How do you handle ERP data migration? We clean and load item masters, BOMs, open orders and opening stock. We run trial migrations and reconcile stock and balances with your team before go-live. ### Can it handle GST e-invoicing and e-way bills? Yes. Invoices and e-way bills are generated through GST Suvidha Provider integrations, and VAT or sales tax rules are handled for UAE, UK and US operations. ### What happens if our process changes later? You own the code, so workflows, fields and approvals can be changed. Most clients keep a small support retainer for ongoing changes. ## Related guides - [Manufacturing software development company](https://infikeytechnologies.com/industries/manufacturing): Infikey Technologies builds manufacturing software: custom ERP, production planning and scheduling, shop-floor execution (MES), inventory an... - [Odoo vs custom ERP: which should your business choose?](https://infikeytechnologies.com/compare/odoo-vs-custom-erp): Odoo is a modular ERP with ready apps for accounting, inventory, sales, purchase and manufacturing, available as a free Community edition or... - [B2B e-commerce platform development](https://infikeytechnologies.com/industries/ecommerce/b2b-ecommerce-platform): A B2B e-commerce platform lets business customers such as dealers, retailers and distributors order online with their own price lists, credi... - [Construction project management software development](https://infikeytechnologies.com/industries/construction/construction-project-management-software): Construction project management software plans and controls building projects: schedules and milestones, daily progress reports from site, B... - [Custom software vs off-the-shelf: build or buy?](https://infikeytechnologies.com/compare/custom-software-vs-off-the-shelf): Off-the-shelf software is faster to start and cheaper upfront, and is the right choice when your process is standard, such as accounting, em... - [Hire a dedicated development team](https://infikeytechnologies.com/industries/startups/dedicated-development-team): A dedicated development team is a group of engineers, designers and QA specialists who work full time on your product under a monthly contra... - [Hospital management system development](https://infikeytechnologies.com/industries/healthcare/hospital-management-system): A hospital management system (HMS or HIS) digitises hospital operations: patient registration, OPD and IPD, billing, pharmacy, lab, radiolog... --- Source: https://infikeytechnologies.com/industries/manufacturing/manufacturing-erp Publisher: Infikey Technologies Private Limited (software, mobile app, AI and cloud development; offices in India, UAE, UK and US).
