Marketplace

OBI + KudTax

Connect your OBI seller account with KudTax to automatically reconcile platform fees, marketplace commissions, payouts and VAT rates across all EU countries into DATEV-ready entries.

The OBI marketplace opens the range to third-party sellers, which brings in a rule many merchants only meet once it becomes a problem: operators of electronic marketplaces are liable under § 25e UStG for VAT their sellers fail to remit. That is why they verify tax registration, and why an expired confirmation is not a formality but a suspension.

What to watch for with OBI

Marketplace liability lands back on the seller

Because the operator is liable for VAT that goes unremitted, it suspends the account before it pays. An expired tax registration or master data that does not match therefore costs not a reminder but the sales channel — in the middle of the season.

Garden and plant lines are reduced-rated

Live plants, seeds and certain garden products carry the reduced rate while the rest of a DIY range does not. Take the rate from the marketplace statement rather than the product data and part of the range is taxed wrongly, permanently.
