Who it’s for
From the freelancer with a few invoices a month to the wholesaler with a warehouse and sales reps.
Invoices and receipts through the provider, clients from the VAT number and collections, with no second subscription for the provider.
Quotes, orders, delivery notes and invoices, with stock, per-client prices and documents in English for clients abroad.
A receipt at the counter with the card on the POS terminal, stock that updates itself and Magento 2 and Stripe connections.
Cleaning, offices, subscriptions: recurring documents are issued and sent on their own, every month.
Their own user, VAT reports and the period pack with every document and the files behind your expenses.
What it does
Invoicing, clients, collections and banking — no spreadsheets and no second program for the provider.
Invoices, receipts and credit notes are issued through a certified provider and transmitted to myDATA automatically, with a MARK on every document.
Type the VAT number and the client’s details are filled in from the AADE registry — or from VIES for EU VAT numbers. Categories, friendly names, full history.
Monthly charges are drafted for review, or issued and sent on their own, every period.
Grow & ScaleEvery payment is allocated to the client’s documents, with partial payments, client credit and receivables aging.

Connections
Data arrives where it is needed on its own, with no typing things in twice.
Every document transmitted through the provider, with a MARK — and your expenses from myDATA, to reconcile them.
Every client’s and supplier’s details from their VAT number, and EU VAT numbers checked in VIES.
Connect your bank through open banking (PSD2): transactions are matched to your documents.
The amount goes to the terminal of supported providers and the receipt is issued once it is approved.
E-shop orders are invoiced, stock is updated and customers join your client list.
Payments you take become draft documents for review, or are issued automatically.
Forward your suppliers’ invoices to your company’s address and AI reads them.
