Before starting the setup of the BMD interface in Moss, make sure a few important points have been clarified and prepared both in BMD and in Moss.
This will save you time later and reduce the need for rework.
Type of Data Transfer
The connection works by exporting booking entries (as CSV files) together with the associated receipts (in a ZIP archive). After import, the receipts and their corresponding entries are automatically linked within BMD.
Set Up the Counter Account for Moss Payments
All transactions conducted via your Moss Wallet (credit card payments, invoice payments, and reimbursements) must be booked in BMD against a dedicated counter account.
Typical options:
Bank Account (e.g.,
2812for Moss Wallet)Credit Card Account (e.g.,
2810)A dedicated Creditor Account for Moss (e.g.,
34000 Moss GmbH)
Export Configuration
Moss uses the booking symbol “MOSS” by default for exporting credit card transactions. If needed, this can be adjusted.
⚙️The export format itself can also be customized via specific field assignment and formatting.
See the separate article: “Customising the BMD Export Format in Moss” for details.
Importing Master Data from BMD
Before exporting, the relevant master data must be imported into Moss:
Chart of Accounts (Accounts from BMD)
Business Partner Accounts (Suppliers)
Cost Centers
Cost Objects
These must be exported from BMD first and then imported into Moss (or added using the Moss Import Template).
Other Important Preparatory Points
Clarify internally which Tax Codes (USt.-Schlüssel) you will be using (e.g., Domestic 20%, Domestic 10%, EU Service RC, EU Goods Acquisition).
If needed, define special accounts for:
Foreign Currency Charges (e.g.,
7790for Bank Charges)Expense Accruals (e.g.,
2900for Prepaid Expenses)
💡 Pro Tip
Make sure your accountant is involved early in the process.
This will save you adjustment effort later and ensure a smooth export!
