Business Central vs Odoo 2027: ERP cost per user for US and UK SMBs

Summary. On licence price, Odoo is cheaper than Microsoft Dynamics 365 Business Central at every comparable tier, though by less than older guides suggest. Microsoft lists Business Central Essentials at $80.00 and Premium at $110.00 per user per month, paid yearly (£61.50 and £84.60 ex VAT in the UK), with Team Members at $8.00 (£6.20) for people who only read, approve or make small edits. Those prices took effect on 1 November 2025. Odoo's US page lists Standard at $24.90 and Custom at $49.00 per user per month on yearly billing, but both are 12-month discounts for the users on your first order; the list prices behind them are $31.10 and $61.00. Custom's list price rose from $46.70 around the turn of 2026. Odoo showed us no sterling price. Implementation moves totals most: Odoo publishes Success Packs from $580 to $25,000, Microsoft publishes nothing, and the two partner price lists we found start at £10,000 in the UK and $11,500 for a single general ledger module in the US. Both products file UK Making Tax Digital VAT returns, both need a tax engine or careful setup for multi-state US sales tax, and UK VAT e-invoicing is due from 1 April 2029.

About this article. For finance and operations leads at US and UK firms choosing between these two ERPs. On 13 November 2026 we checked every price, plan rule and tax feature against Microsoft's and Odoo's pricing pages and documentation, two partners' published price lists, GOV.UK and the Texas Comptroller. Odoo sets prices by visitor location and our direct fetch returned rupees, so the US dollar figures come from Internet Archive copies of Odoo's own US pages. This is general information, not tax or accounting advice; vendors change prices, and no vendor paid for inclusion. Researched with AI assistance and reviewed by our editorial team.

What changed, and what to settle before you sign

Five facts shape a 2027 decision between these two ERPs.

Business Central rose in November 2025. Microsoft's Dynamics 365 blog lists Essentials moving from $70 to $80 per user per month, Premium from $100 to $110 and the Device licence from $40 to $45, its first Business Central rise in more than five years. Storage per licence rose at the same time, to 3 GB for Essentials and 5 GB for Premium. The new prices apply to new subscriptions and to existing ones at their first renewal on or after 1 November 2025 (Microsoft moved the date back from 1 October), so any 2027 renewal is at the higher rate.

Odoo's headline price is a first-year price. An asterisk on Odoo's pricing page limits the discount to 12 months and to the users on your initial order. Users you add later, and every user from month 13, pay list: $31.10 for Standard and $61.00 for Custom on yearly billing, about 25% above the first-year figures.

Odoo Custom costs more than it did a year ago. Archived copies of Odoo's US page show Custom at $37.40 for the first year and $46.70 list on 19 December 2025, then $49.00 and $61.00 by 6 January 2026, a rise of about 31% in the list price. Standard did not change.

AI is priced differently. Copilot is included in both Business Central editions, but its Sales Order Agent and Payables Agent need Copilot Credits, bought prepaid or pay-as-you-go with an Azure subscription. Odoo puts agentic AI in its Custom plan and charges in-app purchase credits for AI scanning of vendor bills and expenses.

UK e-invoicing has a date. A roadmap from HMRC and the Department for Business and Trade, published on 28 October 2026, says VAT-registered businesses must be able to issue and receive VAT invoices as e-invoices from 1 April 2029 unless exempt, with Peppol as the core framework. A technical consultation is due in spring 2027 and detailed requirements between October 2027 and April 2028. No UK law requires e-invoices yet; the regulations are still to come. Our UK e-invoicing 2029 explainer follows the consultation.

Before signing either contract, get four things in writing: the year-two per-user price, the implementation scope and its exclusions, the Peppol route your ERP will use for UK e-invoices, and the sales tax engine you will use if you collect US sales tax in more than one state.

Dynamics 365 Business Central: editions, prices and hosting

Business Central is Microsoft's ERP for small and mid-sized firms, bought through a Microsoft partner. These are Microsoft's list prices on 13 November 2026.

Microsoft's comparison table lists customisation and extensibility, multiple environments and multiple companies on both editions.

Hosting. Business Central online runs in Microsoft's cloud. Each Essentials or Premium customer gets one production and three sandbox environments at no extra charge. Database storage is shared across all environments: 80 GB per tenant plus an allowance per licensed Essentials or Premium user. The capacity page does not state that allowance; Microsoft's November 2025 pricing note sets it at 3 GB per Essentials and 5 GB per Premium licence. Going over the limit does not stop transactions, but Microsoft then restricts creating more environments until you cut data or buy capacity. Each extra production environment, bought through your Cloud Solution Provider partner, adds three sandboxes and 4 GB of shared storage.

Business Central can also run on-premises or in a private Azure deployment, and at least one partner supports only Microsoft's public cloud for its fixed-price packages. Microsoft's pricing page shows no on-premises price, so treat that route as quote-only.

Odoo: editions, prices and hosting

Odoo sells one per-user subscription covering all its apps, from accounting and inventory to CRM, eCommerce and manufacturing. It prices by visitor location: our fetch on 13 November 2026 returned rupees with the same plan structure, so the US dollar figures below come from the Internet Archive's copy of Odoo's US page from 10 November 2026.

All prices are per user per month. The first-year discount applies only to the users on your initial order.

Who counts as a user. Odoo charges for anyone with backend access to create, view or edit documents. That includes an employee who only submits expenses or timesheets and an outside accountant who works in your books. Customers and suppliers who use the portal, and website visitors placing orders, are free. The US page now shows a Light User licence at $8.90 per user per month for staff who only use self-service features such as time off, expenses, attendance, planning or barcode scanning, arranged through an Odoo advisor on a quote. Approving orders and reading finance reports are not on that list, so approvers stay full users.

Standard or Custom. Standard runs only on Odoo Online and cannot use custom modules, Odoo Studio, multiple companies or the external API. Odoo defines the external API as outside software, such as a legacy system or reporting engine, calling into Odoo; calls Odoo itself makes to payment providers, carriers, VoIP or bank feeds are part of Standard. Installing Studio or adding a second company moves you to Custom automatically.

Hosting. Odoo Online hosting is included in the plans, with incremental daily backups on two continents, upgrades at no extra fee and unmetered storage up to 100 GB. Custom also lets you self-host Odoo Enterprise or use Odoo.sh, Odoo's platform for custom code with development, staging and production branches. Odoo.sh is billed separately per worker, per GB of storage and per staging environment, excluding the Enterprise licence; its calculator showed us no figures. On-premise customers must run the latest stable version; our Odoo development guide covers version and upgrade planning.

Sterling pricing. We could not verify a GBP price, so UK buyers need a written quote that states whether VAT is included.

Head-to-head comparison

This summary draws on the pricing pages and documentation cited in the sections above and below.

Implementation and partner costs: only published figures

Implementation usually costs more than the first year of licences. Neither licence price includes it, and Odoo lists implementation services and access to its experts among the things its plans exclude.

Odoo Success Packs. These are prepaid hours with a dedicated Odoo consultant, covering project management, training, data import help and, on larger packs, customisation. US dollar prices are from the Internet Archive's copy of Odoo's US page from 9 August 2026; the live page on 13 November 2026 showed the same packs and discount in rupees.

Odoo says companies under 50 employees usually work with it directly on Success Packs, firms over 50 usually use a local partner, and firms over 250 should contact Odoo. Travel is billed on top, extra modules carry monthly maintenance charges, and performance work needs a pack of at least 50 hours. Odoo bills its own development by the consulting day and does not publish partner day rates.

Business Central partner packages. Microsoft publishes no implementation price. We found two partners that publish fixed prices, one in each market. These are single firms' list prices, not market averages, and we do not endorse either.

• US: Stoneridge Software, Business Central Foundation. General ledger $11,500 (required), accounts payable $9,775, accounts receivable $7,475 and inventory $12,650, each including discovery, configuration, data migration, training resources, testing support, go-live and two weeks of post-launch support. A year-one Essentials support plan at $6,000 is required. Add-ons include basic sales tax setup ($1,000), ACH payments ($2,000), multi-currency ($1,000) and each extra company ($1,000). The package covers Microsoft's public cloud only.

• UK: Infinity Group, BCQuick. A core pack at a fixed £10,000 covers general ledger, purchasing, sales, standard tax and multi-currency in about seven weeks. Expansion packs for inventory, assembly, warehousing or project accounting start at £3,500, and add-on packs for multi-company, fixed assets, consolidation or intercompany start at £2,500. Business Central licences and a monthly support plan are extra; the page gives no support price and does not say whether pack prices include VAT.

Localisation: US sales tax and UK Making Tax Digital

United States

US sales tax is set by states and local jurisdictions, and economic nexus rules mean you can owe tax where you have no office. In Texas, since the 2018 South Dakota v. Wayfair decision, remote sellers with $500,000 or more of Texas revenue in the previous 12 months must obtain a permit and collect state and local use tax, and may choose a single local use tax rate, currently 1.75%.

Business Central. The US version handles sales tax through tax groups, tax areas and tax jurisdictions, and Microsoft notes that states, counties, cities and localities can all charge it. You set up and maintain jurisdictions and rates, and can copy the setup between companies with the Copy Tax Setup task. Microsoft lists IRS 1099 forms (older 1099 features are being retired from version 27.0), IRS 1096 support, and tax improvements planned for 2027 release wave 1. The US version cannot report VAT to European authorities, which matters if you also sell into the EU. The alternative to maintaining rates by hand is a marketplace tax-calculation app, priced by its publisher.

Odoo. The US package follows US GAAP and installs default sales and purchase taxes. For rates by state, county and city, Odoo integrates with Avalara AvaTax, available only to companies located in the United States, Canada or Brazil. You need your own Avalara account and licence, and excise taxes such as fuel or tobacco taxes are not supported. Odoo also exports 1099 data as a CSV file for e-filing through a third party, generates NACHA payment files and prints cheques.

United Kingdom

HMRC says all VAT-registered businesses should now be signed up for Making Tax Digital for VAT and must keep VAT records and file returns with compatible software. When software connects, the authority you grant lasts 18 months.

Business Central. The GB version's HMRC VAT Setup service connection retrieves VAT obligations, submits returns and shows liabilities and payments, with the fraud prevention data HMRC requires. That connection does not handle group VAT or HMRC agent services, cannot send test returns (only real ones), and needs extra setup, including an Azure app registration, on-premises. For group registrations, Microsoft's separate VAT Group Management extension lets member companies submit their VAT to a group representative, who files one return; anyone who calculates and submits returns needs a full user licence.

Odoo. The UK Accounting module adds a chart of accounts ready for CT600 and a tax structure ready for the VAT100 return; UK Accounting Reports sends returns through HMRC's MTD VAT API. Odoo also generates Bacs payment files and files Construction Industry Scheme monthly returns. Two limits: you cannot submit a return through Odoo once it is more than three months late, and in a multi-company database only one company and one user can connect to HMRC at a time. Unlike Business Central, Odoo offers a demo mode for the HMRC flow. For VAT groups, Odoo uses tax units, which work only in multi-company databases and so need the Custom plan.

E-invoicing from April 2029. Odoo acts as both a Peppol access point and a service metadata publisher, lists the United Kingdom among eligible countries and makes Peppol registration free. Business Central's E-Documents framework connects to third-party access points, including Avalara, B2BRouter, Continia, Logiq, Pagero, SignUp and ForNAV. Microsoft has no contract with them, so you contract directly and their services may cost extra. Our Germany e-invoicing ERP checklist covers the formats Business Central supports today.

Decision table: choose Business Central or Odoo

For that last row, our Xero, QuickBooks and Sage MTD comparison covers UK accounting tools.

Worked example: annual cost for a 25-user SMB

Take a 25-person wholesale distributor with one legal entity. Twenty staff work in finance, sales, purchasing and the warehouse; five managers only approve orders and view reports. It holds inventory, sells into several US states or files UK VAT, and needs no manufacturing. All figures are list prices on annual billing as of 13 November 2026, excluding sales tax, VAT and any tax-engine subscription.

United States. Sources: Microsoft, Odoo's archived US pages and Stoneridge.

Odoo counts all 25 people as paying users because the five approvers need more than Light User self-service; Business Central can put them on Team Members. Odoo's packs buy consulting hours; the Stoneridge figure is a fixed scope including data migration, training and two weeks of post-launch support.

United Kingdom. Business Central costs 20 × £61.50 × 12 = £14,760 plus 5 × £6.20 × 12 = £372, or £15,132 a year ex VAT. Adding Infinity Group's £10,000 core pack and a £3,500 inventory pack brings year one to at least £28,632, before its unpublished support plan and any VAT on the packs. Without a verified sterling price, we give no UK Odoo figure.

For this firm, Odoo's three-year US licence cost is 44% (Standard) to 87% (Custom) of Business Central's. Custom's 2026 rise means a firm that needs Studio, several companies or the external API saves far less than older comparisons suggest. Business Central's case rests on Team Members pricing, multi-company in both editions and Microsoft 365 integration.

Implementation checklist

1. Count users by role. Separate who posts transactions, who only approves, and who only logs time, expenses or attendance. That decides Team Members and Light User counts.

1. Price year two. Model Odoo at list ($31.10 or $61.00 in US dollars) from month 13, and ask your Business Central partner whether its support plan renews at the same rate.

1. Pick the plan by integration need. If another system must call the ERP, or you need custom code, Odoo needs Custom; get any Odoo.sh price in writing.

1. Fix the tax route. In the US, pick and budget the tax engine. In the UK, confirm MTD VAT works for your registration type, especially group VAT.

1. Plan for 2029 e-invoicing. Ask which Peppol access point you will use and what it costs per document or per year.

1. Scope data migration. Decide how many years of history move, and in what detail, before you sign.
