Cin7 Core vs Odoo: which is right for your Australian business?
A practical comparison from a partner that implements both. Where each platform wins, where each one struggles, and the size + complexity bands where one is obviously the right choice.
Short answer
Cin7 Core wins for Australian wholesalers, eCommerce sellers, multi-store retailers and light manufacturers who are already on Xero and want a focused inventory + sales platform that goes live in 6–10 weeks. Odoo wins for businesses that need real MRP, project / job-cost workflows, CRM-led sales, or a unified system spanning sales, HR, projects, and accounting in one tenant.
The honest framing
Most “Cin7 vs Odoo” comparisons online are written by partners who only sell one of them, so they reach a predictable conclusion. We implement both. We’re Cin7 partners and Odoo partners. Roughly half our discovery calls end with us recommending Cin7 Core and half end with Odoo. The right answer is genuinely shape-dependent.
The wrong question is “which platform is better?” The right question is: what does your business actually do, and which of these two architectures matches it?
At-a-glance comparison
| What you care about | Cin7 Core | Odoo |
|---|---|---|
| Core focus | Inventory + sales for product businesses | Full ERP suite: sales, inventory, manufacturing, projects, HR, accounting |
| Best fit business size | 5–75 staff, $1m–$30m revenue | 10–500+ staff, $2m–$200m+ revenue |
| Accounting | Designed to sit beside Xero | Built-in accounting (replaces Xero) or integrate |
| Manufacturing | Light — assemblies, BOMs, finished-goods costing | Full — routings, work centres, MRP scheduling |
| eCommerce integrations | Native Shopify, WooCommerce, Amazon, eBay | Native Shopify, WooCommerce, plus own webshop |
| CRM | Basic — contacts, sales orders | Full — pipeline, marketing, automation |
| Project / job costing | Not the right tool | Native — projects, timesheets, job profitability |
| POS | Native B2B/B2C | Native retail POS with offline mode |
| Hosting model | Cloud only (Cin7 hosted) | Cloud (Odoo Online) or self-hosted |
| Customisation | Settings, fields, reports — no code changes | Open source — modules, code, full customisation possible |
| Typical implementation | 4–10 weeks | 8–20 weeks (depends on modules) |
| Per-user licensing | Tier-based (Standard / Pro / Advanced) | Per app + per user (Enterprise) or free Community |
When Cin7 Core is the right call
If most of these are true, Cin7 Core is almost certainly your platform:
- You already use Xero and want to keep it. Your accountant likes it. You don’t want to swap accounting platforms on top of changing inventory.
- Your business sells products (not projects, not services). The unit of work is a SKU.
- You sell across multiple channels — Shopify, Amazon, eBay, B2B, retail — and need one stock pool feeding all of them.
- You manufacture, but it’s assembly-style: build a BOM, allocate components, finished good in. No routings, no work centres, no MRP scheduling.
- You want a fast time to value: live in 6–10 weeks, not 6 months.
- You don’t need a CRM with marketing automation. Sales people use the SO screen and Outlook.
When Odoo is the right call
If most of these are true, Odoo is the platform that’ll save you a year of pain:
- You manufacture and the workflow has routings, work centres, scheduling, capacity. Cin7 Core will fall over here.
- The unit of work is a project, job, or contract — not a SKU. Trades, services, professional services, custom builds.
- You want CRM, marketing, sales, projects, timesheets, helpdesk and accounting in one tenant, not stitched together with Zapier.
- You’re willing to replace your accounting platform (or you don’t have one yet that you’re attached to).
- You need deep customisation — bespoke modules, custom workflows, things no off-the-shelf ERP does. Odoo’s open source codebase makes this possible.
- You’re larger or growing fast and want a platform that scales to 200+ staff without re-platforming.
Where it gets ambiguous
Three scenarios where the answer isn’t obvious from the checklist:
1. Wholesaler doing some manufacturing
Default to Cin7 Core. If “manufacturing” is “we put kits together from purchased components,” Cin7 Core handles it natively. Only move to Odoo MRP when you actually need work-order scheduling and routings.
2. eCommerce + project work side hustle
If projects are <20% of revenue, run Cin7 Core for the eCommerce side and use a simple project tool (Asana + spreadsheets) for the rest. If projects are growing, Odoo unifies both.
3. Outgrowing Xero, but not yet at full ERP scale
You usually don’t outgrow Xero — you outgrow your inventory layer. Cin7 Core sits beside Xero and pushes the load off without forcing an accounting migration. Odoo only makes sense when accounting itself is the bottleneck.
4. Multi-entity / multi-currency / consolidation
Both can do it; Odoo does it more cleanly out of the box (multi-company is a first-class concept). Cin7 Core needs a separate tenant per entity and a consolidation layer in your accounting platform.
What the implementation actually looks like
Both platforms are excellent if implemented properly and painful if not. The difference is mostly in scope:
| Phase | Cin7 Core (typical) | Odoo (typical) |
|---|---|---|
| Discovery + scoping | 1–2 weeks | 2–4 weeks |
| Configuration + integrations | 3–5 weeks | 5–12 weeks |
| Data migration | 1–2 weeks | 2–4 weeks |
| Training | 1 week | 1–2 weeks |
| Go-live + aftercare | 30 days | 30 days |
| Total elapsed | 6–10 weeks | 10–20 weeks |

Common questions
Can I migrate from Cin7 Core to Odoo later, or vice versa?
Yes. We’ve done both directions. Cin7 Core to Odoo is the more common path — usually a business that started in Cin7 Core and grew into needing real MRP or project workflows. Odoo to Cin7 Core happens when a business simplified scope and Odoo became overkill. Either migration is project-sized work, not a button click.
Is Odoo really free?
Odoo Community Edition is open source and free. Odoo Enterprise is paid (per app per user, billed annually). For most Australian SMEs we recommend Enterprise — you get the polished UI, mobile apps, official support and the modules that aren’t in Community (Studio, accounting localisations, advanced manufacturing). Community is real, but the “free” framing oversells how much extra implementation work it is.
Does Cin7 Core replace Xero?
No, and that’s the point. Cin7 Core is designed to sit beside your accounting platform and push journals, invoices, bills and payments into it. You keep Xero as the source of truth for finance. Your accountant keeps working the way they always have.
What about Cin7 Omni?
Different product line. Cin7 Omni (formerly Cin7) is the higher-end platform with built-in EDI, full POS suite and warehouse management. We don’t implement Omni any more — it’s a different beast and we focus on Cin7 Core. If you’re currently on Omni and looking to simplify, see our Cin7 Omni to Cin7 Core migration guide.
Can you implement both for the same business?
Occasionally, yes. We’ve set up businesses where Cin7 Core runs the inventory + sales side and Odoo runs the project / services side, with a Make.com or custom integration moving data between them. It works, but it’s a higher-cost architecture. Most businesses are better served by picking one platform.
How quickly can you tell us which one fits?
30 minutes on a discovery call is usually enough to give you a confident recommendation. We’ll ask about your sales channels, manufacturing complexity, accounting setup, team size and growth plans. By the end of the call you’ll know which platform we’d recommend and roughly what implementation would look like.
Want a recommendation specific to your business?
30 minutes, free, no pitch. We’ll ask about how your business actually runs and tell you whether Cin7 Core or Odoo is the right call — or, occasionally, that you should hold off on either.
