Free all-in-one CRM software

All-in-One CRM Software

An all-in-one CRM software keeps every part of your customer relationship in a single place — instead of leads in a spreadsheet, contacts in your phone, quotations in Word and follow-ups in your head. Catalystk brings lead capture, customer records, contacts, deals, quotations, sales orders and follow-up reminders together, so anyone on the team can see the full history of a customer in one screen.

Leads arrive from your website, IndiaMART, Justdial or a manual entry, get assigned to a salesperson, become a deal with a value and an expected closing date, move through your sales stages, turn into a quotation and then into an order — with every call, email and note recorded along the way.

Deal management is where that pipeline becomes money you can plan around. Each deal carries its value, probability, owner, competitor and expected close date, and the deal journey shows exactly how it travelled: which stage it entered, how long it waited there, what was quoted and revised, who followed up and why it was won or lost. Deals that stall in one stage surface on their own, so a manager can step in while the order is still winnable instead of reading about it in a month-end review.

From those same deals Catalystk builds your sales projections — weighted forecasts by month, salesperson, territory, product and stage — so you can see committed versus likely revenue, compare the forecast against target and actual closures, and give production and purchasing an early view of what is coming. Because it is a free all in one CRM software, that forecasting sits in the same platform as your stock and billing, not in a separate spreadsheet somebody has to maintain.

All-in-One ERP Software

An all-in-one ERP software — or all in one ERP software, as it is often searched — runs the operations behind the sale — what you buy, what you hold in stock, what you make and what you bill. Catalystk is a free all-in-one ERP software that covers purchasing, inventory, manufacturing, billing and accounting in the same system as your CRM, so a confirmed order automatically informs stock, production and finance instead of being re-typed into another tool.

Raise purchase requests and purchase orders against real stock levels, receive goods, produce against a bill of materials, and issue GST invoices that flow straight into your books.

CRM + ERP

All-in-One Business Software

All-in-one business software is what you get when CRM, ERP and day-to-day operations share one database. An all in one business software removes the gaps between departments rather than adding another tool to bridge them. In Catalystk, a lead becomes a quotation, an approved quotation becomes a sales order, the order checks available stock and raises a purchase or work order, the goods are dispatched, the invoice is raised and the payment lands in your accounts — one continuous chain, with no exports, imports or duplicate data entry between departments.

Because sales, purchase, stores, production and finance all write to the same records, your reports agree with each other. Management sees one version of the truth: pipeline value, stock on hand, work in progress, outstanding payments and profitability, all updated as the work happens, on web and mobile.

CRM + ERP

CRM and ERP software in one system

Most growing companies begin with separate tools: one for leads, a billing package for invoices and a spreadsheet for stock. CRM and ERP softwarein one system removes the hand-offs between them. Catalystk’s CRM ERP software shares a single customer, product and price list, so the person who wins an order and the people who buy, make and bill it look at the same record. That is real CRM and ERP integration: not an export between two products, but one database.

As all-in-one CRM ERP software, a confirmed quotation can become a sales order, reserve stock, raise a purchase request or a work order and turn into a tax invoice with nothing retyped. Managers follow pipeline, stock, production and receivables on one CRM ERP platform. Go deeper with free all-in-one CRM software and free all-in-one ERP software.

All-in-One CRM & ERP Software FAQs

Common questions about running your business on one free all-in-one platform.

What is all-in-one CRM software?

All-in-one CRM software handles the whole customer side of a business in one system: capturing leads, storing customers and contacts, managing deals through each stage, sending quotations, recording follow-ups and reporting on what closed. Nothing has to be re-entered between one step and the next, because every record belongs to the same customer file.

What is all-in-one ERP software?

All-in-one ERP software runs the operations behind the sale — purchase requests and purchase orders, multi-warehouse inventory, manufacturing with a bill of materials and work orders, GST billing, payments and accounting. One confirmed order updates stock, production and your books at the same time, instead of being typed into three separate tools.

What is the difference between CRM and ERP software?

CRM covers everything before and around the sale — leads, deals, quotations, follow-ups and service. ERP covers what it takes to deliver and account for that sale — purchasing, stock, production, billing and finance. Catalystk runs both on one database, so a won deal flows straight into purchase, production and invoicing.

Is Catalystk really a free all-in-one software?

Yes. The free plan includes every module with unlimited records, on web and mobile, with no credit card and no time limit. Most businesses go live in about 10 minutes without consultants. Paid Business and Enterprise plans exist only for larger teams that want guided onboarding and priority support.

Is Catalystk a free all in one CRM software?

Yes. Lead capture, customers and contacts, deal management, quotations, follow-up reminders and sales reports are all included on the free plan, with unlimited records on web and mobile. No part of the CRM is time-limited or reserved for a paid tier — paid plans only add onboarding and priority support.

Is there a free all in one ERP software for small businesses?

Catalystk is one. Purchase requests and purchase orders, multi-warehouse inventory, bill of materials, work orders, GST billing and accounting come free under the same login as the CRM, so a small business can run its full operation without buying ERP modules separately or paying per user.

Does the CRM include deal management and sales projections?

Yes. Every qualified lead can become a deal with a value, probability, owner and expected close date, and the deal journey records each stage it passed through. Catalystk weights those open deals into sales projections by month, salesperson, territory and product, so you can compare forecast against target and actual closures.

Do I still need separate billing, inventory or accounting software?

No. GST billing, e-invoicing, stock control and accounting are modules of the same platform, not integrations you buy or connect. An invoice raised against a sales order reduces stock and posts to the ledger automatically, so your sales, stock and financial reports always agree.

Can a small business run its whole operation on one all-in-one business software?

It can. A small business can manage leads and customers, quote, invoice and collect payments, control purchases and stock, run production, log service complaints and read its reports from a single login — with role-based access so each department sees only what it needs.

What is CRM ERP software?

CRM ERP software combines customer relationship management (leads, deals, quotations, follow-ups) with enterprise resource planning (purchase, stock, production, billing, accounts) in one system, so sales and operations share the same customer, product and order records.

Is Catalystk a CRM ERP system or a CRM ERP platform?

Both. It is a CRM ERP system because sales and operations use one database, and a CRM ERP platform because every module — CRM, sales, purchase, inventory, manufacturing, billing, accounting, projects and service — runs inside the same account on web and mobile.

What does integrated CRM ERP software do for a small business?

It removes double entry. A quotation becomes a sales order, checks stock, raises a purchase request or work order and becomes a tax invoice without retyping, so a small team spends its time selling and delivering instead of copying data between tools.

Is Catalystk a complete CRM and ERP solution for small business?

Yes. It covers the full cycle from enquiry to payment — CRM, quotations, orders, purchasing, inventory, production, GST, VAT and sales-tax billing and accounts — and every module is included in the free plan with unlimited users.

Is Catalystk cloud CRM ERP software for businesses in many countries?

Yes. It runs in the cloud, in any browser and on the Catalystk mobile app, and is used by businesses in many countries. Invoices support GST, VAT and sales tax in any currency, with e-invoicing where your country requires it.

Is there CRM ERP software for manufacturing?

Catalystk links customer orders to bill of materials, MRP material planning, job orders and work orders, so sales promises match production capacity and shortages become purchase requests automatically.

Is Catalystk free CRM ERP software?

Yes. The CRM and ERP modules are free forever, with unlimited users and records and no credit card. Paid plans exist only for larger teams that want more.

How do CRM and ERP integration and business management work in Catalystk?

CRM manages customers and sales, ERP manages purchase, stock, production and accounts, and the business management dashboard shows what is due today across both, with approvals and reports in one place.

Can I download CRM and ERP reports in Excel or PDF?

Yes. Every list and report — leads, deals, quotations, invoices, purchase orders, stock, production and profit and loss — can be downloaded free in Excel and PDF, printed or emailed.

Is there a free download of Catalystk?

Catalystk runs in your browser, so there is nothing to install on a computer, and the Catalystk mobile app is a free download. Your data can be exported free in Excel and PDF at any time.
