Odoo vs King.
King stops - what now?

My verdict

King served Dutch trade businesses well for decades, but the clock is now ticking: vendor Bjorn Lunden (formerly King Software) ended support for King Financieel and King Factureren on 31 October 2025, and from 31 October 2026 the software stops working altogether - after that you can only view your data. So the question is not whether to switch, but what to switch to. A like-for-like swap (KING Finance, another bookkeeping package) is the smallest step, but it keeps the patchwork: bookkeeping in one tool, orders, stock and webshop in others. For the trade businesses King was strong in, Odoo is the more interesting move: orders, inventory, purchasing, invoicing, accounting and webshop on one platform. In one line: King's end is forced. What you migrate to is a choice - make it once, and make it count.

At a glance

eCommerce Native Website, eCommerce and Portal Via connectors; no native webshop
CRM & service Native CRM, Helpdesk, Field Service Not the core
Cloud Browser-first (Odoo Online, Odoo.sh, self-host) On-premise; successor KING Finance is cloud bookkeeping

Strongest point Business-wide coherence on one model Decades of Dutch trade heritage

Five questions that decide it

01

The deadline is real - and closer than it feels

Odoo

A well-scoped Odoo implementation for a trade business takes weeks to a few months, not years. Starting now leaves room to migrate calmly, test, and go live before the cut-off rather than in a December panic.

King

Bjorn Lunden ended support on 31 October 2025 and switches King Financieel and Factureren off on 31 October 2026 - after that date the software is read-only. Every King user still running today has months, not years.

Waiting does not improve any option. The earlier you choose, the calmer the migration.

02

Like-for-like swap, or a step up?

Odoo

Odoo replaces not just the bookkeeping but the whole operation King supported: orders, stock, purchasing, invoicing and accounting on one data model, with webshop and CRM native when you need them.

King

The vendor's own successor, KING Finance, is a cloud bookkeeping package - a fine like-for-like swap if bookkeeping is all you used. But many King users ran their trade operation on it; a bookkeeping-only successor keeps orders and stock somewhere else.

If King was just your books, swap like-for-like. If King ran your trade, a forced migration is the one moment a step up costs no extra disruption.

03

Trade and inventory: where King users feel the difference

Odoo

In Odoo, stock is a business-wide process: multi-warehouse, reservations, backorders, lot tracking, valuation tied to finance, and the webshop reading the same stock as the sales desk.

King

King earned its place in Dutch wholesale with solid order and stock administration for its era. That functionality stops developing now - and connectors to modern webshops and platforms get harder, not easier, on software that no longer changes.

The trade depth that made King good is exactly what Odoo continues - on a platform that keeps developing.

04

The patchwork question

Odoo

Odoo keeps one source of truth across sales, inventory, purchasing, service and finance, so fewer separate tools and connectors are needed and the numbers reconcile by default.

King

Around an aging King install there is usually a patchwork already: a separate webshop, Excel for stock decisions, a CRM bolted on. Migrating the bookkeeping alone moves one patch and leaves the rest.

A forced migration is the cheapest moment to replace the patchwork, not just the package that expired.

05

Getting your data out, in time

Odoo

We start every migration with a fit-gap and a data plan: master data, open items, history. Phased, with a dry run before go-live - the same approach as our other migrations from legacy Dutch packages.

King

From 31 October 2026 King is read-only. Exports still work today; the closer to the deadline, the more crowded the migration calendar gets - at every vendor and every partner.

Plan the data export while King still runs normally. That is this year, not next.

FAQ

Odoo vs King, frequently asked questions.

Is King really stopping?
Yes. Vendor Bjorn Lunden (formerly King Software) confirms that support for King Financieel and King Factureren ended on 31 October 2025, and that from 31 October 2026 the software stops working - after that date you can only view your data, read-only.
What is the best alternative to King?
That depends on what King did for you. If it was only bookkeeping, the vendor's own KING Finance or another cloud bookkeeping package is the smallest step. If King ran your trade operation - orders, stock, invoicing - Odoo is the more complete alternative: the whole flow on one platform, including webshop and CRM when you need them.
Can I take my King data to Odoo?
Yes. Master data, open items and history can be exported and migrated - but only while King still runs normally. From 31 October 2026 the software is read-only, and migration calendars fill up as the deadline nears. We run a phased migration with a fit-gap first and a dry run before go-live.
Is KING Finance not the logical successor?
For pure bookkeeping it is a fair option - same vendor, prepared migration path. The honest question is whether bookkeeping was all King did for you. Many King users ran orders and stock in it too; KING Finance is a bookkeeping package, so that part of the operation needs a new home either way. That is exactly where one integrated platform starts to win.
What does switching to Odoo cost?
A full implementation runs roughly €1,000 to €3,000 per user as a one-off, depending on scope, guidance, integrations and how much your team takes on - a trade business with a handful of users typically lands well under a broad manufacturing scope. The honest breakdown is in what does an Odoo implementation cost.
How fast can we be live before the deadline?
A focused trade implementation - orders, stock, invoicing, accounting - typically goes live in weeks to a few months. Starting in the first half of the year leaves room for testing and a calm cut-over; starting in autumn means migrating against the clock alongside everyone else who waited.

King stops. Your operation should not.

Every King user migrates somewhere in the coming months - the only question is whether you move one package or fix the whole landscape in the same effort. Book a Quickscan and we will map what King does for you today, what must move before 31 October 2026, and what one Odoo platform would look like for your trade operation.
