Your payments book themselves,
DATEV-ready for your accountant.
Connect Mollie, Stripe, PayPal and every other provider. Meridian delivers finished DATEV batches, invoices and receipts attached to each booking, every month. One price, however many.
Every provider ships its own report. Your accountant needs one batch.
Mollie, Stripe and PayPal ship three different reports, but no invoices, no tax split and no receipt on the booking. Your accountant does the rest by hand. That is not a workflow. That is a second job.
Five formats in. One clean DATEV month out.
Every provider speaks its own format. Meridian translates all of them into the same booking logic, with the receipt on every booking. Your accountant sees no difference.
From your payment provider to a finished DATEV Buchungsstapel, automatically every month
Connect a provider
One click at your provider, for some a read-only key is enough. Meridian imports the full history and keeps it in sync.

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 your providers and DATEV. In one tool.
Meridian builds the complete revenue side straight from your providers' data. No converting reports, no invoices written somewhere else.
Buchungsstapel, finished every month
Revenue, payments, payouts as EXTF files, import-ready for DATEV. For the current month and every past one, at no extra cost.
OSS split by destination country
Card country, account country, address or customer IP, depending on what your provider delivers. Domestic 19 percent, EU OSS per country with BU 240 and columns AN/AO, non-EU separated.
An invoice for every payment
A section 14 UStG invoice PDF, with its own number range per provider and the correct tax statement.
Fees with the right tax key
Mollie and Stripe with section 13b, PayPal exempt as a banking service. Every provider on your fee account, 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 payouts across all providers and companies in one login, continuously in sync.
Unlimited providers and companies, one price
Main shop on Mollie, subscriptions on Stripe, crypto through CoinGate: connect as many accounts as you want. Every company gets its own batches and accounts, your price stays at €99.99.
Exactly one line on your invoice costs money.
We list the rest anyway, so you can see what the price covers instead of hunting through small print.

I had the same problem every month
I sell digital products myself, through several payment providers. Every close meant pulling reports, matching fees, looking up EU rates, and then the file came back from the accountant because a BU key was missing. Meridian was ground against real DATEV imports until the batch goes through without a question.
4400, 4320 and 4338 for revenue, separate money accounts per provider, 6855 for fees. Accounts are configurable per company and provider 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.

One price that does not grow with your revenue
Everyone in this market bills by volume: per order, per document, per transaction, per provider. When you grow, you pay. Meridian does not.

- DATEV Buchungsstapel (EXTF) for revenue, payments and payouts
- OSS tax split by destination country: domestic, EU OSS, non-EU

- Beleglink via GUID plus document.xml for Belegtransfer

- Missing provider? Integration for free
14 days free, then €99.99 net plus VAT per month. Cancel monthly. This offer is addressed exclusively to businesses (Unternehmer, § 14 BGB).
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, and whoever bills per provider earns from every new channel. Meridian builds the revenue side straight from your providers and costs 99.99 euro. With one provider and with five. At 20,000 in revenue and at 200,000.
The DATEV integration without a document meter.
The established integrations bill by document volume and need a shop system. Meridian books straight from your payment providers, at one fixed price.
As of October 2026. Sources: the providers' public pricing and product pages.
What about the DATEV data service?
Since April 2026 DATEV offers its own data service for payment providers, from 10 euro a month. It produces booking suggestions, but invoices and receipts have to come from another system.
Common questions
Everything founders and accountants want to know before they start.
Mollie, Stripe, PayPal and CoinGate are connected directly, each by login or a read-only key. We set up Klarna, Adyen, GoCardless, Braintree, Paddle, Polar, SumUp and many more for your account on request, and check each one with your account before it books anything. Shopify, Amazon, eBay, Etsy, Kaufland, OTTO, Allegro, Gumroad, ready2order and Lightspeed start soon. Missing an integration? We build it for free.
Use the form on this page to tell us which provider it is. Within 48 to 72 hours on business days you get an honest answer whether and when the direct integration will be ready. It costs you nothing.
No. €99.99 a month covers all providers, all accounts and all companies. There is no meter for documents, transactions or connections.
No. Meridian imports the full history, as far as your provider hands it out, and every one of those months can be exported as often as you like. Many tools in this market charge separately for back exports, we do not.
You invite them by email. They get their own login, see your companies and download the batches with receipts themselves, for every month they need. You stop sending files.
Meridian is built for digital services and goods and covers the standard and reduced rate, small business under section 19, OSS by destination, reverse charge and intra-community supplies, exempt sales under section 4, the margin scheme under section 25a, multi purpose vouchers and both cash and accrual taxation. When you set it up we ask which of these occur in your business and calculate with those only. What we do not cover, we tell you instead of guessing.
Meridian assigns a GUID to every receipt, writes it into the Buchungsstapel as a Beleglink and generates the matching document.xml for DATEV Belegtransfer. On import, DATEV links every booking to its PDF automatically. Your accountant never attaches a single document by hand.
Since April 2026 DATEV offers its own data service for several payment providers, from 10 euro a month (as of October 2026). It produces booking suggestions, but it does not link receipts to the bookings and it needs the invoices from another system. Meridian delivers the complete revenue side with finished batches, section 14 UStG invoices, the OSS split and the receipt on every booking.
As a Generalumkehr (general reversal) on the refund date. The original batch stays untouched and VAT is corrected in the right period. The credit note is generated as a PDF and attached to the reversal booking via Beleglink.
An EXTF file is the DATEV standard format for posting batches: a header row with advisor and client number plus fiscal year, then one line per booking with account, contra account, BU key, document field and Beleglink. DATEV Kanzlei-Rechnungswesen reads it directly. Meridian generates the files preconfigured for SKR04, your accountant maps nothing.
Your next month-end close takes care of itself
Connect your first provider and the first Buchungsstapel is ready, history included. Ask your accountant if this is how they want to work from now on. We already know the answer.
