Odoo vs Other ERP Systems: Which Should You Choose?
Odoo is an open-source ERP that suits most small and mid-sized companies because it covers sales, accounting, inventory, manufacturing and HR in one flexible system without vendor lock-in, while heavyweight platforms like SAP and Microsoft Dynamics are usually built for larger enterprises with bigger budgets. The honest answer is that the right system depends on your size, your processes and your local accounting needs, not on which brand is best known.
How to compare ERP systems honestly
The best ERP is the one that matches your company size, your real processes and your local compliance obligations, not the one with the biggest name. Before comparing tools, it helps to be clear about what an ERP actually does: it brings sales, purchasing, inventory, accounting, manufacturing and HR into a single database so that everyone works from the same numbers.
Odoo is an open-source ERP with more than 30 integrated modules. It comes in two editions, a free Community version and a paid Enterprise version, runs in the browser, has mobile apps, and a Lithuanian localisation can be configured by a partner. Because the platform is modular, you can start with two or three apps and add more as you grow, rather than paying for a giant suite on day one.
LONGRUN (UAB VM Robotika) is an Odoo partner in Vilnius, founded in 2018, with more than 50 Odoo implementations delivered in Lithuania. We compare these options every week with companies that are choosing their first ERP or replacing an older one, so the sections below are written to be fair rather than to sell.
The criteria that actually matter for an SME
- Local accounting compliance - can the system produce i.SAF, i.VAZ, FR0600, GPAIS and SAF-T to VMI correctly.
- Total cost - licences plus implementation plus ongoing support, not just the sticker price.
- Flexibility - how easily the system bends to your processes instead of forcing you to bend to it.
- Integrations - how well it connects to your bank, e-shop, and any tools you already use.
- AI - whether you can layer automation, agents and chatbots on top of your data.
- Vendor lock-in - whether you own your data and can move or self-host if you ever need to.
Odoo vs spreadsheets (Excel / Google Sheets)
Spreadsheets are excellent for one person and one task, but they break down the moment several people need the same up-to-date numbers at the same time. Excel and Google Sheets are flexible, cheap and familiar, which is exactly why so many growing companies run their whole business in them for far too long.
The problems appear quietly. Two people edit two copies and the totals stop matching. A formula gets dragged one row short and an inventory figure is wrong for a month. Nobody can see the link between an order, the stock it consumed and the invoice it produced, because each lives in a different file. None of this is the spreadsheet's fault, it simply was never designed to be a shared operational database.
Odoo replaces that patchwork with one connected system: a sale reserves stock, stock movements update accounting, and accounting feeds tax reports, all automatically. For a company that has outgrown its files, moving from Excel to Odoo usually pays for itself in recovered time and fewer errors, not in fancy features.
| Aspect | Spreadsheets | Odoo |
|---|---|---|
| Single source of truth | No - copies drift apart | Yes - one shared database |
| Multi-user, real time | Limited | Built in |
| Connected processes | Manual, copy-paste | Sales, stock and accounting linked |
| Lithuanian tax reports | Manual | Generated from the data |
| Best for | One person, simple tasks | A growing team running daily operations |
Odoo vs SAP / Microsoft Dynamics for SMEs
SAP and Microsoft Dynamics are powerful, mature ERP platforms, but they are generally designed and priced for larger enterprises, which often makes them heavier and more expensive than a small or mid-sized company needs. For an SME, the deciding factor is rarely raw capability, it is the cost and effort of getting that capability live and keeping it running.
These enterprise suites bring deep functionality, large ecosystems and strong references in big organisations. The trade-off is longer implementations, higher licence and consulting costs, and a level of process standardisation that can feel rigid for a 20 to 200 person company. They are a sensible choice when complexity genuinely demands it.
Odoo sits in a different place. It scales from a handful of users upward, the modular pricing lets you pay only for what you use, and its open-source core means you are not locked to a single vendor. For most SMEs in Lithuania, Odoo delivers the ERP functionality they actually use at a fraction of the total cost. The honest caveat is the mirror image: a very large, highly complex enterprise with specialised industry requirements may still be better served by SAP or Dynamics.
| Aspect | SAP / Microsoft Dynamics | Odoo |
|---|---|---|
| Typical target | Larger enterprises | Small and mid-sized companies |
| Total cost | Higher licences and consulting | Lower, pay for the modules you use |
| Implementation | Longer, more standardised | Faster, more flexible |
| Vendor lock-in | Tied to the vendor stack | Open source, can self-host |
| Best fit | Large, complex organisations | Growing SMEs that want flexibility |
Odoo vs local/legacy accounting systems
Local accounting systems such as Rivile are strong, well-established products built specifically for Lithuanian bookkeeping, and they remain a perfectly good fit for companies whose needs are mainly accounting. The question is what happens when the business grows beyond pure bookkeeping into sales pipelines, inventory, manufacturing and customer service that all need to share data.
Rivile is a Lithuanian accounting and ERP software product with deep local roots. For a company that simply needs reliable accounting under Lithuanian rules, there is nothing wrong with staying on it. The limits show up when you want one system to also run CRM, production, serial-number tracking and warehouse operations, and to connect all of that to the accounting in real time.
This is where Odoo and legacy systems do not have to be an either-or choice. Odoo can integrate with or migrate from Rivile and other legacy systems, so you can keep what works and extend the rest. LONGRUN (UAB VM Robotika) has moved a manufacturer off Rivile onto a single Odoo system, reconciling every balance before go-live so no stock and no cent was lost in the transition - you can read the legacy migration case study for the full detail.
Whichever way you go, Odoo handles Lithuanian accounting compliance properly: i.SAF, i.VAZ, FR0600, GPAIS and SAF-T to VMI can all be generated from the data once the localisation is configured by a partner. That removes the usual fear that moving off a local system means losing local compliance.
Odoo vs other ERP systems: side-by-side
Across the criteria that matter most to a Lithuanian SME, Odoo balances local compliance, cost, flexibility and openness better than most alternatives, while honestly conceding ground to enterprise suites on very large, complex deployments. The table below summarises the comparison at a glance.
| Criterion | Odoo | SAP / Dynamics | Spreadsheets | Local / legacy (e.g. Rivile) |
|---|---|---|---|---|
| Local accounting (i.SAF, i.VAZ, FR0600, GPAIS, SAF-T) | Yes, with localisation | Yes, often via add-ons | Manual | Strong for accounting |
| Cost for an SME | Low to moderate | High | Very low | Moderate |
| Flexibility | High, modular | Lower, standardised | High but fragile | Focused on accounting |
| Integrations | Broad, open APIs | Broad, enterprise stack | Manual | Limited beyond accounting |
| AI (agents, automation, chatbots) | Can be layered on top | Vendor-dependent | None native | Limited |
| Vendor lock-in | Low, open source, self-host | Higher | None | Depends on product |
One more point that is easy to miss: because Odoo is open and the data is yours, you can build AI on top of it. LONGRUN delivers Odoo ERP and AI solutions - RAG, AI agents, chatbots and automation - under one roof, so the same system that runs your operations can also automate parts of them later.
FAQ
Is Odoo better than SAP for a small business?
For most small businesses Odoo is the more practical choice, because SAP is generally built and priced for larger enterprises while Odoo scales down to a few users with modular pricing and faster implementation. SAP can still be the right answer for a small unit inside a very large, complex group, so the honest test is your complexity and budget rather than the brand.
Is it worth moving from Excel to Odoo?
It is usually worth moving from Excel to Odoo once several people need the same up-to-date data and your sales, stock and accounting no longer fit in separate files. Spreadsheets stay great for one-off analysis, but Odoo gives you a single shared database where a sale, the stock it uses and the invoice it creates are automatically connected.
Can Odoo migrate data from legacy systems like Rivile?
Yes, Odoo can migrate data from or integrate with legacy systems such as Rivile, and LONGRUN (UAB VM Robotika) has done exactly this for a Lithuanian manufacturer. Before going live we reconcile every balance against the old system so that no stock and no cent is lost in the move.
Does Odoo handle Lithuanian accounting and tax reporting?
Yes, with the Lithuanian localisation configured by a partner, Odoo produces i.SAF, i.VAZ, FR0600, GPAIS and SAF-T reports to VMI from your operational data. This means you can leave a local accounting system without giving up local compliance.
How much does Odoo cost compared with enterprise ERP?
An Odoo implementation with LONGRUN starts from around 4000 EUR plus from about 275 EUR per month for support, which is typically a fraction of the licence and consulting cost of enterprise suites like SAP or Dynamics. You also pay only for the modules you actually use, so the cost grows with your needs rather than all at once.
What if my company is large and complex - is Odoo still right?
If your company is genuinely large with highly specialised industry processes, a heavyweight platform such as SAP or Microsoft Dynamics may serve you better, and we will tell you so honestly. For the great majority of small and mid-sized companies, though, Odoo covers the ERP functionality they actually use with far less cost and far more flexibility.
