Your Mollie revenue books itself,
DATEV-ready for your tax advisor.
Meridian reads your Mollie payments and turns them into finished DATEV Buchungsstapel, section 14 UStG invoices and linked receipts, every month. Your accountant imports. Done.
DATEV Unternehmen onlineSKR03 / SKR04EXTF§ 14 UStGOSSBooking Mollie payments today means manual work or an expensive tool stack
The DATEV export in the Mollie dashboard books everything against one collective dummy debtor. No VAT, no OSS, no invoices. Mollie itself says you need other data sources to complete your accounting. The usual integrations assume a shop system or a billing tool: if you sell directly through Mollie, via checkout, payment links or API, you are told to buy an additional billing system on top. Add pricing models that get more expensive with every exported document. And in the end your accountant still attaches every receipt to every booking by hand. That is not a workflow. That is a second job.
From your Mollie account to a finished DATEV Buchungsstapel, automatically every month

Your accountant imports
Your accountant pulls the batches into DATEV. Thanks to Beleglink and document.xml, every receipt is already attached to its booking. No manual attaching, no reconciling, no follow-up questions.
DATEV · Stapelverarbeitung
Everything that has to happen between Mollie and DATEV. In one tool.
Other tools convert payment reports or reconcile payments against invoices you have to create somewhere else. Meridian builds the complete revenue side directly from your Mollie data.
Three Buchungsstapel, finished every month
Revenue, payments, payouts: three EXTF files per month, import-ready for DATEV. No converting, no rebuilding, no waiting for the 10th of the following month.
OSS tax split by card country
The card issuing country decides: domestic 19 percent, EU OSS per country with BU 240 and the tax rate in columns AN and AO, non-EU separated. Evidence per Art. 24b of the VAT regulation.
An invoice for every payment
Every Mollie payment automatically gets a section 14 UStG invoice PDF, with the correct tax statement based on card country.
Fees booked correctly on 6855
Mollie fees land on account 6855 with BU 506, reverse charge per section 13b UStG. Exactly the way the accountant expects.
Refunds as Generalumkehr
Refunds are booked as a general reversal on the refund date, with a linked credit note PDF. Cleanly reversed instead of buried in a counter-booking.
The receipt is already attached
GUID Beleglink plus document.xml for DATEV Belegtransfer: every booking arrives in DATEV Unternehmen online with its PDF attached. Your accountant never attaches a document by hand again.
All companies, one dashboard
Revenue, MRR and settlements for all your companies in one login. Unlimited Mollie accounts and organisations, continuously in sync.
Unlimited Mollie accounts, one price
Main shop, second brand, new project: connect as many Mollie organizations as you want. Every company gets its own batches and accounts, your price stays at €99.99.
I had the same problem every month
I sell digital products through Mollie myself, and every close ran the same way: pull the CSV, match fees one by one, separate payouts from payments, look up the rate for every EU country. Then the file came back from the accountant because a BU key was missing. Meridian is what I wanted back then, ground against real DATEV imports until the batch goes through without a question. SKR04 with the accounts your firm actually keeps. EXTF with BU keys, OSS with BU 240 plus EU country and tax rate in columns AN and AO, refunds as Generalumkehr. Exactly one task is left for the firm: importing.
4400, 4320 and 4338 for revenue, 19999, 1809 and 1469 for the payment flows, 6855 for fees. Accounts are configurable per company if your firm uses different ones.
EU revenue with BU 240, destination country and tax rate go into the dedicated DATEV columns, each country in the notation DATEV expects.
Booked on the refund date, the original month stays untouched. The credit note is generated as a PDF and attached to the reversal.
GUID Beleglink in the batch plus document.xml in the receipts package. DATEV links them automatically on import, the firm attaches nothing.

You save 260.01 € a month, 3,120 € a year.
At 3,000 documents Meridian costs you 3.3 cents each, no matter how many there are next month. The price per document above is your assumption, not a statement about any particular provider.
The difference is not the amount, it is the shape. Whoever bills per document earns from your growth. On top of that the usual interfaces need a second subscription, because they require a shop system or a billing tool as the revenue source. Meridian builds the revenue side straight from Mollie and costs 99.99 euro. At 20,000 in revenue. And at 200,000 too.
Flat instead of volume tiers: the Mollie DATEV integration without a document meter
The established integrations come from the shop world: they bill by document volume and assume a shop system or a billing tool as the revenue source. If you sell directly through Mollie, you fall through the cracks. That is exactly what Meridian is built for.
As of July 2026. Sources: the providers' public pricing and product pages.
