Company OS Software: 9 Options, From ERP to Workspace

What a company OS software covers

Company OS software tries to run most of a business from one system: records, money, projects, people and the daily conversation. The phrase is used loosely, so this guide looks at what each product covers rather than trusting the label.

The products fall into two camps. ERP systems and suites grew from accounting and operations, and they hold the official records. Workspaces and AI-first platforms grew from planning and documents, and they hold the daily work.

This guide compares nine options. It overlaps with the business OS guide earlier in this series, and it looks at the same products through a company-wide lens.

Who the main players are

ERP and open-source systems, such as Odoo and ERPNext, cover accounting, stock, sales and operations. They are strongest for companies that want records and processes in one place.

Business suites, such as Zoho One and Bitrix24, add many functions under one bill. Fibery and TeamGrid OS are newer workspaces that build company structure from modules.

Work platforms, such as monday.com, add CRM and docs to boards. Sistava starts from AI Employees and brings the company's core tools into the same workspace.

How we sort them

We sort the nine by how much of the company one system covers, how AI does real work inside it, how clearly the price is shown, and whether you can start today.

Some large vendors blocked or refused our reads, so they are not in this list: Microsoft 365 and SAP blocked our reads, and Oracle returned a block on its AI agents page.

Disclosure: Sistava is our product, and we rank it first. The entry below explains where it fits and where it does not.

1. Sistava

Official site: Sistava

Sistava is an AI workforce platform built for AI-first work from the start. You hire AI Employees for the roles you need, and each one gets its own role, goals, knowledge, tools, files, tasks and access rules.

Your team and your AI Employees work in one company workspace, so they share context instead of passing notes between tools. The built-in modules include a CRM with contacts, deals and companies, a task board, a planning calendar, a mailbox for each AI Employee, and a drive for files.

You can use those built-in modules on their own, or connect the tools your company already pays for. HubSpot and Salesforce can connect to the CRM, for example, but the connection is optional.

AI Employees reach people by chat or by their own email. With the Desktop Companion, an approved AI Employee can also work in browser and desktop apps on a computer you allow.

Risky steps wait for your approval by default, so you decide which actions run on their own. Setup is conversational: you describe the outcome you want, connect what is needed, and the AI Employee helps set up the rest.

Sistava is cloud-hosted, so there is no server project to run before you start. It suits founders, small businesses and teams that want recurring work done, not only recorded. AI is part of the work itself here, not a chat box added to the side.

We think it is the best pick for a company that wants one workspace for the work and AI Employees to run it. It is built for the AI era, so the workspace, the employees and the approval steps were designed to work together.

Where it does not fit: if you need a dedicated accounting ledger or a full payroll run, keep those in their own systems. Sistava is the layer where the work happens, and those systems stay the place where the official records live.

• Best for: teams that want recurring work done, not only tracked.
• Strengths: AI-native design, a built-in CRM, tasks, calendar, mail and files, approvals by default, and optional connections to tools you already use.
• Watch out: accounting and payroll need a dedicated system.
• Ask in a demo: how an AI Employee handles one of your real recurring tasks, and where the approval step appears.

• Price, per month (checked 2026-11-15): Starter at $25, Builder at $50, Founder at $100, and Leader at $200.

2. Zoho One

Official site: Zoho One

Zoho One is one suite of about 50 business apps from a single vendor. It covers sales, marketing, customer service, finance, HR, operations, websites, chat, documents and an app builder.

Zoho presents it as one bill and one login for a company that wants to stop buying separate tools. The suite is aimed at growing businesses, not only very small teams or very large enterprises.

The pricing page says the Standard plan includes AI-powered analytics and business intelligence. The homepage we read did not describe AI in detail, so ask for a demo of the AI features before you rely on them.

Its strength is breadth. Almost every back-office function has a module, so a company can cover most of its work without a second vendor.

Its trade-off is depth. Each module is built for a common case, so a specialized team may still want a dedicated tool for one function, such as a complex sales process or a niche accounting need.

The all-employee Standard plan requires a license for everyone on payroll, which can cost more than the headline per-user price suggests. The flexible plan is priced per user, with no headcount rule, so the total depends on how many people use the suite.

A 30-day trial is available with no card needed. That is enough time to test the finance and sales flows with real data before you commit.

Vendor pages and comparisons quote different figures, and the page does not clearly state the billing period. Treat the pricing page as the source, and confirm the billing period before you compare totals.

Zoho One fits a company that wants one vendor for most functions and is willing to work inside one suite. It is less suited to a team that needs a specialist tool for a single function.

• Best for: growing companies that want one suite and one bill.
• Strengths: wide coverage, a 30-day trial with no card, and one vendor for the whole stack.
• Watch out: every employee on payroll may need a license, and prices exclude VAT.

• Price (checked 2026-11-15): all-employee Standard is US$37 per user per month, first year only. Flexible Standard is US$90 per user per month.

3. Odoo

Official site: Odoo

Odoo is an open-source suite of business apps. Its app list covers finance, sales, point of sale, websites and online stores, supply chain, HR, marketing, projects, helpdesk and productivity tools.

You pick the apps you need, so a small company can start with one app and add more later. The open-source base also means you can run it yourself, which gives control over data and hosting.

Odoo says AI runs across its apps. A dedicated AI app is listed, and the Custom plan lists agentic AI. Some AI features, such as scanning vendor bills, use paid credits that are not included in the plans.

Its strength is control and breadth at a low entry price. The free plan gives one app with unlimited users, which is useful for testing before you pay.

Its trade-off is setup effort. The more apps you switch on, the more planning the rollout needs, and a workflow that crosses several apps is where setup cost shows up.

Hosting and support are listed as included in the plans, but Odoo.sh hosting costs extra. Check which hosting model you need before you compare totals.

Odoo fits a company that has someone who can own the configuration, or a partner who will. Without that owner, a broad app list can turn into a long project.

Pricing is in euros per user per month, and the page does not clearly say whether prices are yearly or monthly. Confirm that before you compare it with dollar-priced tools.

• Best for: teams that want control over the stack and can plan the setup.
• Strengths: open source, a wide app list, and a free plan with one app.
• Watch out: setup effort, paid AI credits, and Odoo.sh hosting costs.

• Price (checked 2026-11-15, euros per user per month): One App Free is €0 for one app with unlimited users. Standard is €11.90 to €18.60. Custom is €22.90 to €33.90. Light user is €4.90 through an advisor.

4. ERPNext

Official site: ERPNext

ERPNext is a free, open-source ERP system from the Frappe ecosystem. It covers accounting, sales, CRM, stock, manufacturing, projects, point of sale, quality, helpdesk and HR in one system.

You can self-host it for free under the GPL-3.0 license, so you pay for your own servers and support instead of licenses. That makes it attractive to companies that want full control of their data.

If you prefer hosting from the vendor, Frappe Cloud is priced per month in dollars. Sites start at $5, servers at $20, and a dedicated tier at $125. Enterprise is by contact sales, and the price is not per user.

The cloud service offers a 14-day trial, then a paid plan. Implementation and consulting costs are not shown on the pricing page, and those costs often decide the real total for an ERP.

Neither page we read describes AI features in any detail. ERPNext fits companies that need accounting and operations in one system and have the skills, or a partner, to run it. Its trade-off is that it is an ERP first, so day-to-day collaboration is thinner than in the work platforms in this guide.

• Best for: companies that need accounting and operations in one system and can run it.
• Strengths: free open source, self-hosting, and a cloud option with low entry prices.
• Watch out: an ERP first, with thinner collaboration, and implementation costs are not shown.

• Price (checked 2026-11-15): Self-hosting is free under GPL-3.0. Frappe Cloud: Sites from $5, Servers from $20, dedicated from $125 a month. Enterprise by contact sales.

5. Bitrix24

Official site: Bitrix24

Bitrix24 is an all-in-one workspace for CRM, tasks, chat and video calls, documents, websites and online stores, HR, and workflow automation. It gathers many functions into one product, so a team can keep customer records and work in the same place.

Its CoPilot assistant works across CRM, tasks, chat and calls. The product also offers an app builder, AI agents, bots and an MCP server, so it can connect to other tools.

AI inside CRM and tasks is limited on the lower tiers. Check which tier includes the features you want before you buy, because the AI depth changes by plan.

Pricing is one flat fee per organization by user tier. Adding people inside a tier does not change the price, which rewards a team that fills its tier and can be expensive for a team that sits just over a limit.

The homepage says the free plan covers unlimited users. The pricing page limits it to one or two users, so we used the pricing page for our figures.

A Vibe+ launch offer is listed as valid until December 10, 2026. Check whether it still applies on the day you buy.

Bitrix24 fits small and mid-size teams that want many functions on one bill. Its trade-off is breadth with a learning curve: many menus, many options, and AI depth that depends on the tier.

In a demo, ask how the CoPilot handles one of your real CRM tasks, and which tier includes that feature. Ask the same about the user limit for your team size.

• Best for: small and mid-size teams that want many functions at a flat price.
• Strengths: CRM, tasks, chat, documents, sites, HR and automation in one product, with a flat fee per tier.
• Watch out: AI depth depends on the tier, and the free plan limit differs between pages.

• Price (checked 2026-11-15, US$ per organization, monthly or billed yearly): Basic is $69 or $49 for 5 users. Standard is $144 or $99 for 50 users. Professional is $289 or $199 for 100 users. Enterprise runs from $579 or $399 for 250 users up to $11,499 or $7,999 for 10,000 users.

Some of the work in this list is personal: the calendar, the inbox, and the follow-ups that slip through the cracks. A personal assistant can take that layer on, so the team can focus on the company work covered above.

6. TeamGrid OS

Official site: TeamGrid OS

TeamGrid OS describes itself as an AI-native business operating system. It puts projects, CRM, billing, time tracking, attendance, email, calendar, files, forms, workflows and analytics on one shared data layer.

The AI assistant is included in every seat, with chat, voice and agents. The agents act on workspace data, so they can work across modules rather than inside one chat box.

The vendor claims 15 AI agents, 80 AI tools and more than 1,200 teams. We did not test those claims, so treat them as the vendor's own numbers.

There is no free plan, but a 14-day trial needs no card. Enterprise is available for 100 or more seats through sales.

Pricing is per user, with add-ons for each module, so the total grows as you switch modules on. A 10-person team with email and workflows pays $410 a month billed monthly, which shows how add-ons stack.

The base plan includes 250 AI credits per user per month, and extra credits cost $0.01 each. The homepage and the pricing page disagree on the annual discount, 17% against 20%, so confirm it before you buy.

TeamGrid OS fits service teams that want projects, CRM and billing together. Its trade-off is cost creep, so plan the module list before you start the trial.

In a demo, ask which module you would switch on first, and what the monthly bill looks like with it. Then ask how the agents show you what they changed.

• Best for: service teams that want projects, CRM and billing in one tool.
• Strengths: a wide module list, AI included in every seat, and a trial with no card.
• Watch out: no free plan, and add-ons raise the price quickly.

• Price (checked 2026-11-15, US$): base is $10 per user per month billed monthly, or $8.50 billed yearly on the homepage. Email is $13 and Workflows is $18 per user per month. Billing, Deal Pipeline and Forms are $18, $18 and $6 a month flat.

7. VanderBase

Official site: VanderBase

VanderBase is an AI-native business OS aimed at founders, operators and modern teams. It combines CRM, an AI inbox, content and social publishing, a website builder, lead generation, calendar, finance, analytics and an AI Studio.

Its copilot, Kairos, keeps workspace memory, drafts replies and content, forecasts revenue and plans work. Agents act across modules and follow approval controls before sensitive steps.

It lists no projects, docs or HR module, so it is narrower than the suites in this guide. It is built around sales, marketing and communication rather than the full company.

The product is pre-launch. The homepage banner says public beta, and the body says pre-launch, and early access runs by waitlist with Q4 2026 cited.

Pricing is per workspace with usage limits, not per user. The free plan includes 100 AI credits, one workspace and two agents.

Pro is $59 a month and Business is $149 a month, billed monthly, with higher caps on workspaces, agents and audit events. Storage add-ons run from $9 to $179 a month.

The AI credit allowance for the paid plans is not stated, so ask before you plan your usage. Early access by waitlist also means you may not be able to start on your own timeline.

VanderBase fits founders who want sales and marketing in one place and can wait for access. In a demo, ask how Kairos handles one of your real follow-up tasks, and what the approval step looks like.

• Best for: founders and operators who want sales and marketing in one place.
• Strengths: a copilot with workspace memory, agents that follow approval controls, and a free plan.
• Watch out: pre-launch status, waitlist access, and no projects, docs or HR module.

• Price (checked 2026-11-15, US$ billed monthly): Free is $0. Pro is $59 a month. Business is $149 a month. Storage add-ons run from $9 to $179 a month.

8. Fibery

Official site: Fibery

Fibery calls itself an operating system for the whole organization. Its promise is one connected workspace that replaces scattered tools.

It covers CRM, projects, feedback, docs, OKRs, hiring, employee management and finance templates. Templates give a team a starting structure, and you then shape it to fit how the team works.

Its AI can brainstorm, automate tasks and find data across the workspace. A remote MCP server lets outside AI agents connect, so tools built elsewhere can read and act on it.

The vendor says customer data is not used to train its models. Paid plans include monthly AI credits per seat, at 250 on Standard, 500 on Pro and 1,000 on Enterprise.

Extra AI credits cost €15 per 1,000, up to a spending cap. Observers and guests are free on paid plans, which matters for companies with many light users.

Every new workspace gets a 14-day Pro trial. That is enough time to model one real process, such as turning an idea into a shipped feature or a lead into a paid invoice.

Fibery fits product, software and operations teams that want to design their own structure. Its trade-off is that you build more of that structure yourself than you would with a ready-made suite.

In a demo, ask how you would model one of your own processes from start to finish. Watch how much of the setup you do by hand, because that is the real cost of the flexibility.

• Best for: product, software and operations teams that want to shape their own structure.
• Strengths: one connected workspace, AI that works across it, an MCP server, and free observers and guests on paid plans.
• Watch out: you build more of the structure yourself, and AI credits are capped per seat.

• Price (checked 2026-11-15, euros per user per month, billed yearly): Free is €0 for up to 10 users plus 10 guests. Standard is €12, Pro is €20, and Enterprise is €40 with at least 25 paid users.

9. monday.com

Official site: monday.com

monday.com is a work management platform that many teams already use for boards, projects and simple CRM. The site describes it as an AI work platform where people and agents run business work together.

Its product list covers boards, CRM, service, development, docs, dashboards and automations. AI is central to the pitch: prebuilt and custom agents, an assistant, a notetaker and workflows are all listed, and AI use is metered in AI credits.

On the pricing page, plans are per seat per month in euros, billed annually. Free is €0 with unlimited time, Basic is €9 with 1,000 AI credits, Standard is €12 with 2,000 credits and 250 automation actions a month, and Pro is €19 with 3,000 credits and 25,000 actions a month. Enterprise is custom.

CRM, service and development are priced separately, so the total depends on which products you switch on. The pricing page was only partly readable in our check, so confirm the module prices before you budget.

monday.com fits teams that want visual boards and AI agents on a tool they already know. Its trade-off is that the AI credits and the extra products add cost quickly.

• Best for: teams that want visual boards and AI agents on a work tool they already know.
• Strengths: a broad set of work products, prebuilt and custom agents, and a free plan with unlimited time.
• Watch out: CRM, service and development are priced separately, and AI use is metered.

• Price (checked 2026-11-15): Per seat per month, billed annually, in euros: Free €0 (unlimited time); Basic €9; Standard €12; Pro €19; Enterprise custom.

Which fits which

• AI Employees running the company day to day: Sistava.
• One suite and one bill: Zoho One, or Bitrix24 for a flat fee.
• Open source and control: Odoo, or ERPNext if you can self-host.
• Projects, CRM and billing together: TeamGrid OS, after its trial.
• Your own structure: Fibery.
• Visual boards with CRM: monday.com.

The verdict

Sistava is first because it runs recurring work with AI Employees on top of a built-in workspace. The ERP and suite options hold more of the official records, so accounting and payroll often stay with them.

Pick by which part of the company you want to run first, and test your top two on that part during the trial.
