ERP software, ERP system and ERP solutions
ERP software records what a company buys, stores, makes, sells and spends in one shared database. An ERP system replaces the separate registers each department used to keep, and ERP solutions differ mainly in which modules they include and how much they cost to run. Catalystk was built as ERP software India businesses can start using on day one, and it now serves companies in India and in many other countries: tax-ready documents, prices in your currency and number series for invoices, purchase orders and goods receipts, with GST e-invoicing and HSN/SAC codes for India.
For owners searching for free ERP software India teams can rely on, in India and in many other countries, Catalystk is free forever, not a trial. It is business ERP software that connects procurement, inventory, production, billing and accounts, and over 10,000 businesses already use it. As free business ERP software, every module and every user is included without a credit card, so a small trading firm and a large multi-branch manufacturer both get the same tools. NASSCOM shortlisted Catalystk, and the product keeps adding features without asking customers to pay for upgrades or move to a new version.
Free all-in-one ERP software for small business and SMEs
All in one ERP software means you stop stitching tools together. Catalystk is an all in one ERP system where the purchase team, the stores, the shop floor and the accounts desk all work on the same records. As complete ERP software, it covers purchase requests, supplier quotes, purchase orders, goods receipt, multi-warehouse inventory, bills of materials, MRP, work orders, tax invoices (GST, VAT or sales tax) and finance reports. Because it is integrated ERP software, a goods receipt updates stock instantly and a sales invoice shows up in the ledger without an export.
Many products sold as ERP software for small business are cut-down versions of large-company systems. Catalystk was designed as ERP software for SMEs from the start and scales to businesses of every size: short forms, sensible defaults and a setup that takes minutes. It is free ERP software for small business with no cap on users, items, warehouses or transactions, and it is a free ERP system you keep for good. If you also sell to customers, the free all-in-one CRM software runs on the same account.
- Purchase, inventory, manufacturing and accounts in one login
- No limit on users, items, warehouses or transactions
- Same data on the web and the Catalystk mobile app
Web-based and online ERP software for small business
Web ERP runs in the browser, so there is nothing to install and nothing to back up on office PCs. Catalystk is web ERP software you open at login.catalystk.com from any computer. Teams looking for free web ERP often worry about hidden limits, but this web ERP software free plan has none: it is free web ERP software for every user. Some buyers search for web ERP software free full version for small business; with Catalystk the free plan already is the full product, and you can read more on the ERP software free download page.
Online ERP for small business should also help you serve customers better. Catalystk is ERP for small business that is integrated with CRM features, which helps enhance customer management and service, and the AMC management software logs service contracts and tickets in the same place. As online ERP software it simplifies data-flow management between sales, purchase and production, and creating a new invoice takes seconds. This free online ERP software is an online ERP system and an ERP system for small business that works the same from the office or a client site.
Cloud ERP software for traders and manufacturers
Cloud ERP keeps your data on secure servers instead of a single office machine, so a power cut or a broken laptop does not stop the business. Catalystk is cloud ERP software for traders who buy and resell and for manufacturers who convert raw material into finished goods. As cloud based ERP software it updates itself: new features appear without downloads, patches or IT staff.
A cloud based ERP for small business has to be easy to reach from anywhere. Catalystk is cloud ERP for small business with CRM features to maintain business relationships, so the sales team sees what the stores and production teams see. This cloud ERP system eases data-flow management because every record is entered once and read by every module. Traders can check stock across warehouses before quoting; manufacturers can see shortages from MRP before promising a delivery date. It is free cloud ERP software with no per-user fee, and the same account opens on the Catalystk mobile app. Financial transactions are recorded as they happen, so daily business reports are always current. Cloud ERP software for traders and manufacturers lets you manage business from the office, the shop floor or on the road.
ERP system and ERP application software for small business
An ERP system is only useful if people actually use it. Catalystk is an ERP system for small business traders and manufacturers that enhances customer relationships, streamlines the sales and purchase process, and records and tracks every financial transaction. As ERP system software it gives each department its own screens while keeping one set of items, suppliers, customers and stock. Those looking for an ERP system download will find there is nothing to install; see the ERP software free download page for how access works.
The ERP application works on the web and as the Catalystk mobile app. This ERP application software lets a store keeper check stock, a manager approve a purchase request and an owner open a profit and loss report from a phone. It is ERP application software for small business, so screens are short and the terms are familiar. As an ERP system application and a practical ERP solution, it bundles ERP tools such as approvals, document number series, print settings and 500+ reports.
Enterprise resource planning system for small business
An enterprise resource planning system plans the use of money, material and people across the company. Catalystk is an enterprise resource planning system for small business that turns those plans into daily work: purchase requests become orders, orders become stock, stock becomes finished goods and invoices. As enterprise resource planning software it keeps production, purchase and sales on one timeline, with CRM tools to build customer relationships alongside.
Owners often compare a small business ERP system with spreadsheets and accounting-only tools. The difference is that small business ERP software links every transaction to the item, supplier and warehouse it affects, so reports reconcile without manual work. Some people look for an enterprise resource planning system full version or an enterprise resource planning software download; Catalystk runs online and the free plan includes every module, and the ERP software free download page explains the mobile app and data exports. Day-to-day activity, from vouchers to GRNs, is captured in reports you can filter by branch and date.
Purchase and procurement ERP
Buying is where many businesses, small or large, leak money. Catalystk works as purchase management software and procurement management software in one: a department raises a request, it passes multi-level approval, and suppliers get an RFQ link they can answer without logging in. Read more on the free procurement software page, which covers free purchase management software in detail. The purchase requisition software and RFQ management software pages show those steps screen by screen.
Once a supplier is awarded, purchase order management software turns the quote into a PO in one click, with payment terms and transport details carried over; see purchase order software. When the material arrives, GRN management software records what was received, and the goods received note software updates stock in the chosen warehouse straight away. Purchase requisition software, RFQ management software and GRN management software all feed the purchase invoice, so accounts can match bills against what was ordered and received.
Supplier and vendor management software
Good buying starts with good supplier data. Catalystk acts as supplier management software by keeping supplier master records with contacts, addresses, tax registration details (GST, VAT or sales tax) and the full history of RFQs, quotes, orders and invoices. When a new requirement comes up, you pick suppliers from the master, send each one an RFQ link and wait for their replies to land in the system.
As vendor management software, Catalystk compares supplier quotes side by side, item by item, so price, delivery and terms are visible on one screen before you award the order. The award can be split across vendors or given to one, and the purchase order is created from the winning lines. Because every quote and order stays linked to the vendor record, you can review past rates before negotiating again. Supplier statements and pending payments come from the same records, so the purchase team and accounts never argue over figures. Vendor lists and comparison sheets export to Excel and PDF whenever an auditor or partner asks for them.
Inventory and multi-warehouse stock management
Catalystk works as warehouse management software for businesses that hold goods in more than one place. Multi-warehouse stock is tracked per location, with stock transfers between warehouses, batch and serial numbers, and reorder levels that flag items before they run out. Live valuation shows what the stock is worth today, not at the last month-end.
As inventory management software it ties every movement to a document: a GRN adds stock, an issue to production removes it, and an invoice reduces finished goods. That makes it reliable stock management software, because the balance on screen always has a paper trail. It is also free inventory ERP software, since stock connects directly to purchase, production and accounts. For billing-led businesses, the billing and inventory management software and billing and stock management software pages explain the selling side, and sales and inventory management software covers order-to-dispatch.
- Stock by warehouse, batch and serial number
- Transfers between warehouses with a full audit trail
- Reorder levels and live stock valuation
Manufacturing and production management ERP
Manufacturers need production management software that knows what goes into each product. Catalystk starts with bill of materials software: each finished item lists its components and quantities, see BOM software. MRP then checks the BOM against open orders and stock, showing which materials are in stock and which are short, and lets you firm the plan and convert it to a work order or purchase request; see MRP software for small business.
As manufacturing ERP software, Catalystk handles job orders for outside processing and work orders for in-house production, issuing materials from the right warehouse. Product costing adds material and other costs so you know the true cost per unit before you price it. For the full feature list of free manufacturing ERP software, visit the free manufacturing ERP software page. Production, purchase and stock share one record, so a shortage found by MRP becomes a purchase request in one click.
Finance and accounting ERP
Catalystk is finance management software that sits on top of real transactions. Vouchers, customer ledgers and pending payments are built from the invoices, receipts and purchase bills your team already records, so there is no second round of data entry. As accounting ERP software it posts sales and purchases automatically and keeps a running view of who owes you and whom you owe.
Selling starts with tax-compliant invoices (GST, VAT, sales tax): Catalystk includes GST billing software that also handles VAT and sales tax, with e-invoicing where your country requires it, and the full feature set is on the free billing software page. Finance reports such as profit and loss can be run by branch and date range, giving owners a monthly picture without waiting for an accountant. Payment reminders reduce late collections, and every report can be printed, emailed or saved in Excel and PDF. For vouchers, ledgers and statements in depth, see the accounting software page.
ERP automation and approvals
ERP automation software removes the chasing that slows busy teams down. In Catalystk, a purchase request moves through multi-level approvals before an RFQ can go out, and each approver sees the request, its items and its value on one screen. Once approved, the next document is created from the last one: the awarded quote becomes the PO, the PO becomes the GRN, and the GRN updates stock.
The same workflow idea runs through the rest of the system. Document number series, print settings, terms and conditions and the company logo are set once and applied automatically. Invoices, orders and reports can be emailed from the record, and payment reminders go out without anyone writing them by hand. Project teams can add milestones and milestone billing through the free project management software, which uses the same customers and invoices. Because approvals and automated steps leave a trail, managers can see who approved what and when, and download that history in Excel or PDF.
ERP reporting software
Data is only useful when someone reads it. Catalystk is ERP reporting software with 500+ reports ready to run: purchase registers, pending POs, GRN summaries, stock by warehouse, batch and serial reports, MRP shortages, production costing, sales registers, outstanding payments and finance statements. Each report can be filtered by date, branch, item, supplier or customer.
Reports draw on live transactions, so the stock report and the accounts report agree. Owners can open them on the web or on the Catalystk mobile app, and managers can print, email or download them in Excel and PDF for meetings and audits. For dashboards and cross-module analysis, see the business reports and analytics software page. Because every ERP module writes to the same database, a single report can show the path from purchase request to invoice for an item, something hard to rebuild from separate spreadsheets. Saved filters make it quick to repeat the same weekly or monthly review.
How to choose the best free ERP software
The best ERP software for one company can be wrong for another, so judge any product against your own process rather than a feature list. Start with the documents you create every week: purchase requests, POs, GRNs, invoices, work orders. Then check whether the system handles them without workarounds, and whether stock and accounts update on their own.
When comparing options for the best free ERP software, look past the headline price. Some free plans cap users or transactions, lock reports or remove the mobile app. Ask how long setup takes, whether your data can be exported at any time, and whether tax invoicing (GST, VAT or sales tax) is built in. The checklist below covers the points that matter most to traders and manufacturers of every size.
- Free for every user, with no record or transaction limits
- Purchase, inventory, manufacturing and accounts in one database
- GST, VAT and sales-tax billing built in
- Multi-warehouse stock with batch and serial tracking
- Approvals on purchase requests
- Web access plus a mobile app
- Reports you can download in Excel and PDF at any time
Free download: ERP reports in Excel and PDF
Every ERP report and document in Catalystk has a free download button. Purchase orders, GRNs, stock statements, MRP plans, profit and loss and the rest of the 500+ reports can be saved in Excel for further analysis or as PDF for sharing with suppliers, auditors and banks. You can also print or email them straight from the screen, and there is no charge per export.
Looking for ERP software free download? Catalystk runs online, so there is nothing to install on your computer, and the Catalystk mobile app is free to download. The ERP software free download page explains how to get started, and if you are weighing self-hosted options, the open source ERP software page compares that route with a free hosted ERP. Either way, your data stays yours: export it in Excel or PDF whenever you need it.
