Spent 3 weeks trying to ditch spreadsheets — here's what I learned comparing Google Sheets, Zoho Inventory and Odoo (and Moulmall a tool I'm building)
Quick disclosure up front so I don't get banned: I'm building one of the tools below (MoulMall). I'll mark it clearly when I get to it and I'll give you the real trade-offs, not a sales pitch. Mods, feel free to nuke if this isn't allowed — but I think the comparison part is genuinely useful regardless of which tool anyone picks.
Context: My wife is running a small clothing business and was managing ~300 SKUs across many locations in one country, all on Google Sheets. It worked until it becomes overwelmed as a tool: overselling stuff, wrong stock counts after returns, no team management, no clue what the actual margins are. Spent about 3 weeks trialing the obvious options before building my own. Here's the honest breakdown.
1. Google Sheets / Excel
What people don't admit: for under ~50 SKUs and one location, it's genuinely fine. Free. Flexible. Everyone on your team already knows it.
Where it breaks:
- No real-time sync between people (yes, Sheets has it, no, it doesn't work when 3 people are editing at once)
- No automatic stock deduction when you invoice
- "Low stock alerts" = a conditional format you'll ignore
- Multi-location = a different tab and a lot of crying
- Reporting = whatever pivot table you can build at 11pm
Cost: $0, but the hidden cost is the hours you lose reconciling and the orders you lose to stock-outs.
2. Zoho Inventory
Free plan is real (1 user, ~50 orders/month, 2 locations). Paid plans start around $29/mo (Standard, annual billing) and go up to $249/mo (Enterprise).
Pros:
- Mature product, lots of features
- Integrates with the rest of the Zoho ecosystem (Books, CRM)
- Good for multi-channel selling (Amazon, eBay, Shopify)
Cons:
- The free plan limit is orders per month, not products. If you process more than 50 orders, you're paying.
- User seats are expensive: Standard and Pro only include 2 users. Need a 3rd person? Extra ~$7.50/user/month.
- UI is dense. Onboarding a non-technical employee takes real time.
- If you're not already in the Zoho universe, the integrations matter less than they sound.
3. Odoo
The "free" plan is one app only. The moment you install a second module (say, Inventory + Invoicing), you're on the Standard plan. In the US that's ~$24.90/user/month annual. In Europe/MENA it's cheaper. Custom plan jumps to ~$37–47/user/month.
Pros:
- Insanely powerful. If you can configure it, it does basically anything.
- Community edition is genuinely free if you self-host (and have technical skills)
- One platform for accounting, inventory, CRM, manufacturing, HR
Cons:
- Per-user pricing kills small teams. 5 users on Standard = ~$125/mo just for licenses, before any implementation work.
- Setup is not a weekend project. Most SMBs end up paying an Odoo partner $3k–$10k+ to implement.
- It's an ERP. Treating it like "just inventory software" misses what it actually is, and you'll be overwhelmed.
4. MoulMall — what I'm building ⚠️ this is my product, biased section
Built it because Zoho felt over-engineered for a 2-person shop and Odoo felt like buying a tractor to mow the lawn. Free plan (1 user, 10 products, unlimited orders), then $19/mo Starter (5 users, 500 products), $49/mo Growth (20 users, 5,000 products, multi-warehouse).
Honest about where it's worse:
- Way fewer integrations than Zoho. No Shopify/Amazon connector yet.
- No manufacturing/MRP module. If you actually make things, Odoo is the answer.
- It's new. Zoho has 10+ years of edge cases solved that I haven't hit yet.
- No mobile app (only mobile web), Zoho has one.
Where I think it's better for some people:
- Pricing scales by product count, not per-user. 5 or 20 users costs the same at the tier.
- Free plan is forever-free, not a 14-day trick.
- Setup is genuinely minutes, not weeks.
URL is in my profile so I'm not link-spamming the post.
TL;DR — my honest recommendation regardless of what you pick:
- Under 50 SKUs, one person: Sheets is fine, don't overthink it
- You're in the Zoho ecosystem already: Zoho Inventory
- You need full ERP (accounting + inventory + manufacturing) and have budget for setup: Odoo
- You're a small/mid team that just needs clean inventory + invoicing without the bloat: try something lighter (mine, inFlow, Sortly, whatever fits)
Happy to answer questions on any of the four. What are you all currently using and what made you pick it?
