Odoo vs Rillet (2026): which should you pick?

Pick Odoo if

• Fits if you want double-entry books with your whole team in them and no other Odoo app
• Works for businesses that need their country's taxes and e-invoicing set up for them

Look elsewhere if

• Pricey if you add a second app, as every user then pays per month, your accountant included
• Watch out: the advertised paid prices last 12 months, then renew at $31.10 or $61 a user a month, billed yearly
• Skip it if you want something to learn in an afternoon: it's a big system, and implementation help is sold separately
• Tight if you scan lots of bills or send texts, since both use credits bought on top
• Pricey if you need the API, Studio or several companies on a paid plan, as they all mean Custom at $61 a user a month

Pick Rillet if

• Fits if you're a mid-size finance team that wants a ledger with revenue recognition
• Makes sense if you run several entities and use Salesforce or Stripe

Look elsewhere if

• Skip it if you want a price before talking to sales
• Not for you if you're a freelancer or sole trader, as it's aimed at mid-size and enterprise teams
• Watch out: customer counts and the share of transactions posted automatically are the vendor's own claims, unchecked
• Watch out: no free plan or trial is listed

Odoo

• Odoo is a wider suite: a second app moves you to a paid plan priced per user for every app, and on paid plans Studio or several companies mean Custom.
• The advertised prices are a 12-month discount for the users first ordered; plans then renew at $31.10 or $61 a user a month, billed yearly.
• Every backend user pays, including an outside accountant and staff who log expenses; limited-access employees can be $8.90 Light Users via an advisor.
• Not included: implementation services, Odoo.sh hosting, and in-app credits for text messages and AI bill scanning.

Rillet

• No prices are published; the pricing page sends visitors to a Talk to Sales form, so costs are unknown until you request a demo.
• It is aimed at mid-size and enterprise finance teams, not freelancers or sole traders.
• Claims such as customer counts and the share of transactions posted automatically are the vendor's own and were not checked.

Odoo

Bank synchronization

Connects to more than 28,000 banks worldwide, and Odoo says AI matching reconciles about 95% of transactions automatically.

Bill and receipt capture

AI reads vendor bills and expense photos taken on the mobile app. The scanning uses in-app purchase credits sold apart from the plans.

Invoices and follow-ups

Country setups and e-invoicing

Charts of accounts, taxes, reports and electronic invoicing formats such as Peppol are preconfigured by country.

Reports and deferrals

Real-time financial reports that can be annotated and exported, plus deferred revenue and expense entries.

Rest of the suite

Paid plans add every other Odoo app, including sales, purchase, expenses, inventory, CRM, HR and point of sale.

Rillet
