Adding new suppliers to Moss

There are three ways of how to set up suppliers in Moss;

Automatic sync with an accounting integration - If you connect an accounting integration to Moss (e.g. DATEV, XERO, ExactOnline and more) your suppliers will be synced automatically with your suppliers from your accounting integration.
Import CSV of all suppliers - If you’re adding more than just a handful of suppliers in one go, we recommend you to import a CSV of all your suppliers. Simply export your Suppliers from your accounting software and upload them via our Supplier CSV template. This will then add all of your suppliers to Moss in one batch.
Manually add suppliers to Moss - If you only need to add one or two new suppliers to Moss, it’s simple to add them manually one by one. Either add new ones via the Accounting page, or when assigning the supplier to a specific invoice. You can choose between adding two types of suppliers:
1. Company suppliers: suitable for corporations, partnerships, or any form of organised business entity.
2. Individual suppliers: suitable for freelancers, sole proprietors, or any individual providing goods or services without a registered business entity.

You can always change the type of the supplier while editing the account.

Supplier details to set up in Moss

Editing Suppliers in Moss

You can edit and delete existing suppliers in Moss. If you change supplier accounts, or any other details of a specific supplier, simply go to "Settings" > "Accounting" >“Suppliers”, where you can edit each supplier individually by clicking on them.

⚠️ Please note that any edits to existing suppliers will also be updated on any invoice that you’ve assigned this supplier to.

Invoice Splitting with Supplier Rules

You can define rules for specific suppliers to automate invoice splitting. Moss allows you to create templates for splitting invoices for all suppliers. Once set up, these templates automatically apply to future invoices from the same supplier.

How to set up Invoice Splitting with Supplier Rules

There are two ways to set up supplier rules:

Navigate to "Settings" > "Accounting" > "Supplier", select the supplier, and scroll to Default accounting attributes. From there, you can split details and set default accounting attributes such as expense account, VAT rate, cost center, cost carrier. These rules apply to future invoices from the supplier.
Alternatively, when adding a split to an invoice, you can save it as a supplier rule directly from the invoice. This rule will be automatically applied to subsequent invoices from the same supplier.

Allocate expenses by using supplier rules

You have two options for expense allocation:

Fixed Amounts: By setting fixed amounts for expense allocation using supplier rules, these specified amounts will always be applied to subsequent invoices from the same supplier
Percentage Allocation: Alternatively, with percentage allocation, the total invoice amount will be divided according to the predetermined percentages you set. This allows for a proportional distribution of expenses based on the specified percentages.

When you receive an invoice, the system automatically applies any saved rules associated with the supplier. This ensures consistency and reduces the need for manual adjustments.
