Accounting fields: settings reference

Overview

Several fields across your Frisbii Billing account feed into your bookkeeping: they identify a customer or subscription for your accounting system, determine which VAT rate applies, or control how your data looks once it's exported to DATEV, SAP, or CSV. This article brings every one of those fields together in one place, grouped by where you configure them, so you know what each one is for and where to find it.

Note

This is a reference article, not a setup guide. For step-by-step instructions on any individual feature, follow the links in the tables below or check Tax management, Accounting export, and Invoices and credit notes. Always confirm tax and bookkeeping requirements with your tax advisor or accounting team — Frisbii Billing does not guarantee that any pre-filled value is correct for your business.

Customer fields

These fields live on the customer record and affect how invoices are taxed and identified in your accounting.

Field	Where to find it	What it's for
VAT ID	Customer record	Required for Reverse Charge to apply to a customer's invoices. Also used to validate cross-border B2B sales within the EU. A customer with a VAT ID is treated as a business customer and isn't eligible for the EU withdrawal right.
Country (billing address)	Customer record	The country of the customer's billing address. The basis for determining which VAT rate applies to a customer's invoices, unless a shipping address overrides it (see below). Compared with your account country to decide whether a sale is domestic, EU, or third country.
Billing address / Shipping address	Customer record; can be overridden on a manually created invoice	The customer's address is the billing address. The optional shipping address has its own name, company, VAT ID, address, and contact fields. Both are added automatically to every invoice, including scheduled subscription invoices. If a shipping address is set, its country takes priority over the billing address country when Frisbii Billing determines the applicable tax rate.
Customer is related to merchant (Organschaft)	Customer record (checkbox)	Marks the customer as a related company within your VAT group (Organschaft / fiscal unity). Invoices are issued with 0% VAT and your Organschaft exemption text. This flag takes precedence over the country-based tax determination and applies to domestic customers only.
Debtor ID	Customer record (assigned automatically or manually, or via the API)	Identifies the customer as a debtor account in your accounting export. Configure automatic assignment under Configurations → Finance and accounting → Accounting export. A manually assigned Debtor ID should always be lower than the next number the automatic sequence will assign.

Product fields (Plan, Add-on, Usage-based billing product)

These fields live on your product catalogue, under Configurations → Product catalogue, and determine how a product is taxed and how its revenue is categorised once billed.

Field	Where to find it	What it's for
Tax setting / flat VAT rate	Plan, Add-on, or Usage-based billing product	Determines which VAT logic applies to the product: either a Tax setting (a set of country-specific VAT rates managed under Tax management) or a flat VAT percentage. Can be changed per product at any time.
Cost object	Plan, Add-on, or Usage-based billing product	Identifies what a cost or revenue belongs to — a product, order, or project — so it can be analysed in your accounting export. This is a different dimension from Cost center (see below): Cost object answers "what is this revenue for," Cost center answers "where in the business did it occur." Filterable in the Subscriptions Report, Plan Report, and Accounting Export. Can be overwritten at subscription level.

Where to find it

What it's for

Tax setting / flat VAT rate

Plan, Add-on, or Usage-based billing product

Determines which VAT logic applies to the product: either a Tax setting (a set of country-specific VAT rates managed under Tax management) or a flat VAT percentage. Can be changed per product at any time.

Cost object

Plan, Add-on, or Usage-based billing product

Identifies what a cost or revenue belongs to — a product, order, or project — so it can be analysed in your accounting export. This is a different dimension from Cost center (see below): Cost object answers "what is this revenue for," Cost center answers "where in the business did it occur." Filterable in the Subscriptions Report, Plan Report, and Accounting Export.

Can be overwritten at subscription level.

Subscription fields

These fields live on the subscription and travel with every invoice generated from it.

Field	Where to find it	What it's for
Cost object	Set only when you create the subscription, on the Create subscription page, above the start-date selection	Overrides the product's Cost object number for this subscription. Leave it blank to inherit the value from the Plan, Add-on, or Usage-based billing product. Once the subscription is created, this value is shown read-only on the subscription details page — it can no longer be edited from the accounting info card.
Cost center	Subscription details page, Accounting information card — editable at any time	Records which organisational unit (department, team, location) the cost or revenue belongs to. Exported as KOST1 in DATEV exports and available as a field on invoice PDFs (see Invoice field configuration below).
PO number	Subscription details page, Accounting information card — editable at any time	Records the purchase order number this subscription relates to, for matching against your customer's own purchasing records. Available as a field on invoice PDFs.
Sales rep ID	Subscription details page, Accounting information card — editable at any time	Records the internal ID of the sales representative associated with the subscription, for reporting in your accounting or CRM system.
Order ID	Subscription details page, Accounting information card — editable at any time	A free-text reference linking the subscription to an external order.

Note

Cost object and Cost center are two different accounting dimensions, both standard in German cost accounting (DATEV): Cost object (Kostenträger) is what the cost or revenue is for; Cost center (Kostenstelle) is where in the business it occurred.

Invoice and credit note fields

Configure these under Configurations → Finance and accounting → Invoices and credit notes.

Field	What it's for
Subscription invoice handle prefix	Custom prefix for the internal handle assigned to every invoice (default "inv"). Changes take effect immediately.
Sequence counter type (invoice number)	Resets your invoice accounting numbers monthly, yearly, or never. Yearly resets happen on 1 January, monthly resets on the first of each month.
Digits count (invoice number)	The fixed minimum number of digits in your invoice numbers, padded with leading zeroes.
Invoice sequence prefix	Custom prefix for invoice accounting numbers (default "IN"). Applies from the next invoice on.
Dynamic placeholder (invoice number)	Adds the invoice's date, month, or year into the invoice number, in one of several formats.
Next invoice number	The number your next invoice will be issued with; increases by one with every invoice.
Invoice number after reset	The number the counter restarts from after a periodic reset.
Credit note sequence prefix, Next credit note number, Next credit note number after reset	The same options as above, for a separate credit note number sequence (default prefix "CN"). Off by default — credit notes share the invoice sequence unless you turn this on. Digit count, dynamic placeholders, and reset timing always match the invoice number settings.
Field configuration	Adds any of the following to your invoice and credit note PDFs: Customer handle, Subscription handle, Account VAT ID, Invoice handle, Debtor ID, Customer e-mail, Cost center, PO number.
VAT exemption texts: Reverse charge, Third country, Organschaft	Three editable, translatable texts printed on invoices and credit notes as the reason for 0% VAT: Reverse charge (cross-border B2B sales within the EU), Third country (customers outside the EU, including Switzerland, Norway, Iceland, and the UK), and Organschaft (related companies in your VAT group). Each field starts with a generic placeholder text. Replace it with the wording your local regulations require and confirm it with your tax advisor.
E-invoicing (Factur-X / ZUGFeRD)	Turns on hybrid e-invoice generation (Factur-X 1.0.07 / ZUGFeRD 2.3, profile EN16931) for every invoice and credit note PDF. Make sure your account's VAT ID is up to date before enabling this.

Tax management fields

Configure these under Configurations → Finance and accounting → Tax management.

Field	What it's for
Tax setting	A named list of countries and the VAT rate to apply for each. Frisbii provides a standard Tax setting with rates for the 20 most important European countries — review and adjust these with your tax advisor, as Frisbii doesn't guarantee they're current or correct for your business.
Remaining countries rate	The fallback VAT rate applied within a Tax setting when a customer's specific country isn't listed. This entry can't be removed.
Default Tax setting	The Tax setting suggested automatically when you create a new product or invoice. Only one Tax setting can be the default at a time; it can always be overridden per product or invoice.
Reverse Charge (toggle, per Tax Policy)	Shifts responsibility for VAT reporting from you to the customer on cross-border B2B sales within the EU. Applies only when the customer's country differs from your account's country (both in the EU), the customer has a VAT ID configured, and the product's Tax Policy has Reverse Charge enabled.

Accounting export fields

Configure these under Configurations → Finance and accounting → Accounting export.

Field	What it's for
Enable accounting export	Turns on automated export of your accounting data. Requires your account Timezone to be set correctly, Invoice numbering to be turned on, and either automatic Debtor ID assignment or a Debtor ID set on every customer.
Export format	DATEV (for Germany's DATEV accounting software, or any tool compatible with its format) or CSV (a neutral, general-purpose format).
Export interval	How often exports are generated: monthly (on the 1st, for the previous month), weekly (every Monday, for the previous week), or daily (every day, for the previous day).
Include header (DATEV)	Whether the export file includes a DATEV header (EXTF-format) or not (ASCII-format). Requires DATEV consultant and DATEV client to also be filled in.
DATEV consultant, DATEV client	Your DATEV consultant number and client ID, included in the export file header. If you don't use DATEV itself but a DATEV-compatible tool, you can enter dummy values here.
G/L account length	The number of digits your general ledger account numbers use. Note: in DATEV, this length can't be decreased again once it's been increased.
G/L account chart type	SKR03 or SKR04 — determines the standard account numbers used for postings (domestic, EU, non-EU, B2B, B2C, payments, and deferrals).
Overwrite Standard Chart of Accounts	Replaces any of the standard G/L account numbers with your own account numbers, per account type.
Override Deferral Booking Numbers	Overrides the BU-Schlüssel (the additional DATEV tax/posting code) attached to a specific G/L account, per tax type — without changing which account number is used. Leave unset to keep the system default. Doesn't affect the separate alternate revenue export report.
Automatically assign Debtor IDs to new customers, starting number	Assigns each new customer a Debtor ID automatically, starting from the number you configure. A manually assigned Debtor ID must always be lower than the next automatically assigned one.
Google Drive / OneDrive / SFTP transfer settings	Delivers your accounting export files automatically to your own Google Drive (client secret, folder ID), OneDrive (client ID, client secret, tenant ID, drive ID, upload path), or SFTP server (server URL, user, password, port, path).

Account and organisation fields

Configure these under Configurations → Admin and billing → Account settings.

Field	What it's for
VAT registration number	Your own company's VAT ID. Printed on invoices and credit notes, and required to be up to date before enabling e-invoicing.
Default VAT percentage	The fallback VAT rate applied when a customer has no country configured at all. Acts as a global fallback below the customer country and Tax setting logic.
Account country	Your company's own country. Compared with the customer's country to determine whether a sale is domestic, EU, or third country for tax and DATEV account mapping purposes, and therefore which VAT exemption text is printed on invoices.
Timezone	Must be set accurately for your accounting export to generate correctly.
