Account Numbers (Swiss Standard)

Chart of Accounts Hierarchy

Slonge Billing reflects the full Swiss SME chart-of-accounts hierarchy. Every account sits on one of four levels, recognizable by the number of digits:

Key points:

• Only entries at the Account level (4 digits) are bookable. Classes, main groups, and groups exist purely for structure and appear in the balance sheet / income statement as subtotal rows.
• In the account list, levels are visually indented and styled — you can see at a glance what is a bookable line and what is a group header.
• All pre-built chart-of-accounts templates (Minimal, Standard SME, IT & Consulting, Freelancer) follow this hierarchy and can be extended with your own accounts and groups.

Creating an Account

1. Go to Accounting > Accounts
2. Click on New Account
3. Fill in:

Opening Balance

When you switch to Slonge Billing, you typically don't start from zero — cash, bank, receivables, and payables already carry a balance from your previous bookkeeping. Under Accounting > Opening Balance, you can record these starting values for the relevant accounts:

1. Go to Accounting > Opening Balance
2. Enter the opening date
3. Fill in the balances for the accounts shown (e.g., 1000 Cash, 1020 Bank, 1100 Receivables, 2000 Payables)
4. Save

Which accounts are available?

All active, bookable balance-sheet accounts from your chart of accounts are shown: assets, liabilities, and equity. This also covers industry-specific accounts such as loans or accruals outside the usual SME number ranges. Group headings, profit-and-loss accounts and the class 9 closing accounts (opening balance account, income statement, balance sheet) cannot be posted to — the latter are technical closing accounts and not part of the balance sheet. Posting an opening balance to the opening balance account would be circular, since that account is the counter-entry of the booking itself.

If an account is missing from the list — a capital account, for example — add it first under Accounting > Chart of accounts.

Balance equation: Total assets must equal total liabilities plus equity (Assets = Liabilities + Equity). Slonge Billing validates this on save and rejects unbalanced entries.

Note: Saving again fully replaces the existing opening-balance entry (document number EB-<year>-001) rather than adding to it. Always enter the complete balances for all affected accounts each time you save.

Swiss VAT

VAT Rates

VAT Calculation

For expenses, VAT is included in the gross amount:

Net = Gross / (1 + VAT rate)
VAT = Gross - Net

Example (8.1%):

• Gross: CHF 108.10
• Net: CHF 100.00
• VAT: CHF 8.10

Input VAT

Input VAT on purchases is booked to account 1170 (Input VAT).

Closing

Month-End Close

1. Review all bookings
2. Create reports
3. Lock the period (optional)

Year-End Close

1. Create balance sheet and income statement
2. Book the annual result
3. Export for tax/auditor

Slonge Billing automates this flow with a guided wizard under Accounting → Year-End Close: 10 automatic checks, posting the net result to account 2990, locking the period, and producing a complete accountant binder (PDF binder always; optional AbaConnect XML / CSV / Receipts ZIP).

Frequently Asked Questions

What is double-entry bookkeeping?

Every booking has at least two lines: debit and credit must be equal. This ensures consistency.

Can I correct bookings?

Yes, as long as they're not locked. After closing, you should make reversing entries.

How do I export for my accountant?

Under Accounting > Export you can export data in Abacus or ASR format.

What does "VAT-relevant" mean?

Accounts where VAT-liable transactions or input tax are booked.
