Odoo alternatives

Last reviewed

Odoo starts at $22.80 a user a month, but small firms are sent to paid setup packs from $615 to $24,790, and Shopify needs a paid connector. In reviews, users most often report slow support after the sale, a steep learning curve and sales promises that weren't kept.

Is Odoo right for you?

Odoo does almost everything: accounting, manufacturing, inventory, a website, point of sale. If you have a technical owner or a partner you trust, want every part of the business in one system and are happy to move your accounting into it, Odoo can be worth the setup.

If you sell mostly on Shopify and Amazon and want to know what to order, when, and what it costs, you are paying for a project to get there. Here is what that looks like, from the people who did it.

Odoo and Kerno, side by side

What Odoo users report Kerno
Getting started “We have paid well over $5000 trying to impliment, and hiring an implimentation parter would have cost us an additional $7600.” Runs alongside what you use now. Connect Shopify and Amazon, or import a CSV, and see your own numbers straight away
Learning it “Once you get past the learning curve it does the job, but don’t expect it to be plug and play.” Built for small teams: a few users, no ERP project, nothing to configure before it’s useful
Price $22.80 to $36 a user a month, plus setup packs from $615 and a Shopify connector from $199 Free during early access, then a founding price you keep for as long as you stay
Forecasting Reordering rules that order when stock falls below a minimum you set. No demand forecast documented Built in. Every purchase order is drafted from the forecast, with the reason behind each quantity. Confirm it, or autosend
Shopify and Amazon A paid connector for Shopify. Amazon stock isn’t pushed automatically, and FBA stock is adjusted by hand Shopify and Amazon connected from the start. One live stock count across every warehouse and channel
Accounting Odoo replaces Xero or QuickBooks, so your books move too Invoices, cost of goods and supplier bills sync to QuickBooks Online or Xero. Your accountant keeps their tools
Support “you often feel left on your own once the project starts.” We read every request ourselves
Sales promises “From the start, sales made promises they simply didn’t keep” What you see on this page is what you get. Try it on your own data before you decide
Leaving “It is virtually impossible to migrate away.” No card, no contract. Export everything as CSV whenever you like

Quotes are from Odoo’s reviews on Trustpilot, connector reviews on the Shopify App Store and an r/ecommerce thread, 2025 and 2026.

What Odoo users like, and where Kerno stands

  • It does everything. “It does so much more out of the box and is massively configurable.” Kerno does one job end to end instead: stock, from the factory order to the invoice, with nothing to configure before it’s useful.
  • A low price per user. True, until the setup hours, connectors and partner work are added. Kerno has none of those to buy.
  • Helpful support chat. It’s what Odoo’s five-star reviewers praise most, often by name. With Kerno you talk to the people who build it.
  • Shopify connectors that work. Several brands say theirs runs without trouble once set up. Kerno’s connections to Shopify and Amazon are built in, not bought.

What Odoo users report

From the reviews we read, by how often each comes up. Counts are the reviews we saw, so they are minimums.

  1. Support after the sale. About 11. “Even after contacting a manager, there is no resolution—you are sent back to the same support team again.”
  2. Complexity and the learning curve. About 9. “Odoo can be a bit overwhelming”
  3. Sales promises. About 8. “So having been told one thing by sales I get told another by customer services”
  4. Billing and renewals. About 8. “Odoo automatically renewed our annual subscription and charged USD 489.60 to our stored payment method.”
  5. Implementation cost. About 7. “after 4 months of investing significant time, money, and resources, we have been left deeply disappointed.”

Ratings: Trustpilot shows 3.1 from 1,303 reviews, split almost evenly: 45% five stars and 43% one star. Capterra lists Odoo at about 4.2.

Budget

Your buying plan by month: stock arriving, what you pay and when (deposits included), against the budget you set.

MonthForecast salesStock arriving, at costPaid to suppliersBudgetLeft
December$142,000$10,070$9,540$15,000$5,460

May$108,000$11,700$11,000$12,000$1,000

March is $4,400 over budget.Spring stock for the 1 l bottle launch lands then. Move its second order to April, or raise March’s budget; the forecast shows what each choice does to stock.

Plan to a sales target

Set a target and Kerno shows the stock it takes. To reach $650,000 from December to May, 8% over the forecast, you’d buy about $8,400 more, mostly bottles and gift boxes, and pay $2,600 of it in March.

Frequently asked questions

How much does Odoo really cost?

Odoo's pricing page shows Standard at $22.80 to $36 a user a month and Custom at $40.90 to $65.40, with the lower prices discounted for the first 12 months. Firms with fewer than 50 staff are pointed to paid Success Packs, from $615 for 4 hours to $24,790 for 200 hours. Shopify needs a paid connector, from about $199. For five users, the first year comes to roughly $4,700 to $6,500 on Odoo's own published prices, before any partner work.

Is Odoo hard to set up?

Many reviewers say so. The learning curve is the most repeated product complaint in the reviews we read, Odoo's own pricing page sends small firms to paid setup hours, and reviewers report spending $5,000 or more before going live. Others, mostly with a partner or a technical owner, run it well.

Does Odoo work with Shopify and Amazon?

Not out of the box for Shopify. You buy a connector, from about $199 to $615, and the cheapest syncs on a schedule and pulls stock in by hand. Odoo's Amazon connector creates orders but does not push stock to Amazon automatically, and FBA stock is adjusted by hand.

Can I keep Xero or QuickBooks with Odoo?

Odoo has its own accounting, so most firms move their books into it. Kerno syncs invoices, cost of goods and supplier bills to the QuickBooks Online or Xero your accountant already uses.

What do Odoo users like?

How much it can do and how far it can be configured, a low price per user, helpful support chat agents, and Shopify connectors that work once they're set up.
