Twinfield on Oliver POS
Twinfield (Wolters Kluwer) receives Oliver POS counter sales through the WooCommerce + Twinfield connector — Dutch and UK accountant-led accounting with unified online + in-store revenue.
How Twinfield works with Oliver POS for WooCommerce
Twinfield, owned by Wolters Kluwer, is the accountant-led cloud accounting platform used heavily in the Netherlands and the UK. The WooCommerce + Twinfield connector posts orders as Twinfield sales transactions and customers as Twinfield debiteuren. Oliver POS writes register sales into WooCommerce, Twinfield picks them up — the accountant works from one unified ledger across online and in-store revenue.
What Twinfield pulls from WooCommerce
The Bizzy WooCommerce + Twinfield connector (and equivalents from AnyTime and other Dutch IT firms) syncs WooCommerce orders into Twinfield as sales transactions, customers as debiteuren, and refunds as credit notes. Twinfield then handles the BTW workflow, the multi-administration accountant workflow, and the standard Dutch financial reporting.
Oliver POS sales become WooCommerce orders; the Twinfield connector treats them identically to online orders.
Why in-store sales matter on the Twinfield ledger
Twinfield is the platform of choice for many Dutch accountant practices because it's designed for accountant-led bookkeeping at scale. Clients hand over the data, the accountant works in Twinfield, and the books come back clean. A POS that doesn't feed Twinfield breaks the workflow.
Oliver POS on WooCommerce keeps the Twinfield workflow whole. In-store sales become Twinfield sales transactions automatically, and the accountant works from one ledger.
How the WooCommerce + Oliver + Twinfield sync works
Cashier rings the sale on Oliver POS, captures the customer, tenders. Oliver writes a WooCommerce order. The Twinfield connector creates or matches a Twinfield debiteur, posts a sales transaction with line items and BTW codes, and records the payment against the configured Twinfield bank dagboek.
Best fit for retailers who…
Twinfield on Oliver POS suits Dutch and UK SMB retailers whose accountant practice has standardised on Twinfield — typically mid-sized boutiques, specialty retailers, and small chains.

Common questions about Twinfield on Oliver POS
Will the Twinfield kostenplaatsen (cost centres) work for multi-outlet Oliver POS retailers?
Yes. The WooCommerce + Twinfield connector can map each Oliver POS outlet (carried as a WooCommerce store or order metadata) to a Twinfield kostenplaats, so per-outlet reporting works inside Twinfield.
Does the Twinfield BTW workflow stay correct with Oliver POS sales feeding in?
Yes. Twinfield calculates BTW from the synced sales transactions. WooCommerce orders rung on Oliver POS carry the right BTW code, and Twinfield's BTW workflow runs on the unified data.
Does Oliver POS have a partnership with Twinfield?
No. Oliver doesn't partner with Twinfield or any other accounting platform. We support Twinfield because its WooCommerce connector already pulls orders, refunds, taxes, and customers from your store — and Oliver writes every in-store sale into WooCommerce as a standard order, so the same connector picks it up automatically. Your accounting subscription, your ledger, and your contract stay between you and Twinfield.
Does Oliver charge extra to use Twinfield?
No. You pay Twinfield's standard published pricing directly to Twinfield. Oliver doesn't take a markup, doesn't insert itself into the data flow, and doesn't charge a per-transaction or per-journal-entry fee on top.
Do register sales from Oliver POS reach Twinfield?
Yes. Every Oliver POS sale is written to WooCommerce as a standard order with the customer, line items, taxes, and payment method attached. The Twinfield WooCommerce connector treats that order the same way it treats an online order: it posts the same invoice, journal entry, or sales receipt, with the same tax splits and the same customer record. There's no separate "POS sync" to configure.
How fast does a register sale reach Twinfield?
It depends on the Twinfield connector's sync mode. Connectors that push per-order (most Twinfield integrations support this) post the invoice or sales receipt into Twinfield within seconds of the cashier closing the sale. Connectors set to a daily summary post a single end-of-day journal entry with per-tax, per-payment-method, and per-outlet splits. Either way, no manual entry is required.
Will my in-store and online sales reconcile against one set of books in Twinfield?
Yes. Oliver POS writes register sales into the same WooCommerce store that powers your online checkout, so by the time orders reach the Twinfield WooCommerce connector they're already a unified order stream. Twinfield sees one revenue feed, one tax-liability total, and one customer ledger — no manual reconciliation between an online and an in-store set of books.
