This page explains how to correctly define the length and format of the Customer number and the Invoice number when invoicing with Banana Accounting Plus.

Important: Correctly setting the Customer number and the Invoice number is essential, especially if you issue Swiss QR invoices and want to automatically record payments. Both numbers are included in the reference number on the QR slip and are used to automatically link imported payments to the related invoices.

This setting applies to:

• Invoicing integrated in the accounting file (with or without Swiss QR)
• Invoicing with the Estimates and Invoices application (with or without Swiss QR).

Customer number

The Customer number is the identifier of the customer in accounting (subaccount or cost center). In QR invoices, it is also used to automatically record payments of the invoices.

Customer number format for QR invoices

In QR invoices, the customer number is included in the reference number. For this reason, it must follow specific rules, which vary depending on the type of account used (IBAN or QR-IBAN) and the type of reference number chosen.

• QR Invoice with IBAN account:
  • Only numbers or letters are allowed (A‑Z, 0‑9).
  • Spaces, separators, or other characters (-, /, #, etc.) are not allowed.
    If you insert separators or other characters, they will be removed from the invoice printout and may cause problems in automatically recording payments.
  • Customer number + Invoice number ≤ 19 characters.
    The two numbers together must not exceed 19 characters. It is recommended to keep the Customer number to a maximum of 7 characters.
• QR Invoice with QR-IBAN:
  • Only digits (0–9) are allowed.
  • No spaces, letters, separators or other characters (-, /, #, etc.). If you insert separators or other characters, they will be removed from the invoice printout and may cause problems in automatically recording payments.
  • Maximum length 7 digits.
  • Customer number + Invoice number: together must not exceed 14 digits.

Customer number format for invoices without QR

For invoices without QR, there are no constraints regarding the format of the customer number. Best practices apply.

Best practices for customer numbers

• Uniqueness: each customer must have a unique number.
• Consistency: use a fixed scheme (e.g. 1000001, 1000002, etc.).
• Compatibility: if you plan to issue QR invoices with both standard IBAN accounts and special QR-IBAN accounts, or switch from IBAN to QR-IBAN, use only numbers.

Invoice number

The Invoice number uniquely identifies the invoice (mandatory). In QR invoices, it is also used to automatically record payments.

For invoices without QR, there are no constraints regarding the invoice number. Best practices apply.

Best practices for invoice numbers

• Uniqueness: each invoice must have a unique number.
• Consistency: use a fixed scheme (e.g. year+progressive: 2500001, 2500002, etc.).
• Compatibility: if you plan to issue QR invoices with both standard IBAN accounts and special QR-IBAN accounts, or switch from IBAN to QR-IBAN, use only numbers.

Banana财务会计程序总是要在收入入账的那一行输入增值税代码。收款时需要缴纳增值税，收入账户也会被相应地记录。客户管理是通过成本中心3的利润中心来完成的。

在这种情况下，为了登记客户并开具发票，就必须：

• 在会计科目表中设置利润中心成本中心3的客户分类账。
• 在客户菜单设置中，选择成本中心3利润中心组。
• 当开具发票记录时：
  • 发票。
  • 在成本中心3列中输入成本中心3的利润百分比 (无借记或贷记账户) 。
  • 在同一行中，在方括号 [V81] 之间输入销售税代码。
    插入方括号内的增值税代码允许您查看发票中的增值税金额，而不需要在记录发票时进行会计处理。

In integrated invoicing, invoices are created and recorded in the same file. Regarding accrual-based accounting, invoices must be recorded at the time of issuance.

In accrual-based invoicing management, it is necessary to set up the customer subaccount in the Accounts table as shown in the balance sheet.

• All customer accounts must have complete data (first name, last name or company name, address), because when creating the invoice, the program uses this data for the invoice header.

It is possible to create and record invoices with or without VAT.

Accrual-based Invoice

In the accrual-based system, the invoice is created to be sent to the customer, and it is recorded at the same time.

Therefore, with a single transaction, both the invoice is created and recorded:

• In the Date and Doc. column, enter the date and any document number.
• In the Invoice column, enter the invoice number.
  It is important that the invoice number complies with certain requirements: see how to correctly create the invoice number.
• In the Description column, enter the items to be invoiced that should appear on the invoice.
• In the Debit column, enter the customer's account from the subaccount.
  It is important that the customer number complies with certain requirements: see how to correctly create the customer number.
• In the Credit column, enter the revenue account.
• In the Amount column, enter the gross amount.

Accrual-based Invoice and VAT – Effective Method

The standard procedure in Banana Accounting for VAT management requires entering the VAT code on the same row where the income is recorded.

Issued invoices are immediately recorded and posted. Income is recognized at the time the invoice is issued.

Therefore, in accrual-based VAT management, the VAT code is added when the invoice is created.

The invoice data is entered in the Transactions table. For each new invoice, enter a new transaction row.

• Enter the date of the transaction
• The invoice number
  It is important that the invoice number complies with certain requirements: see how to correctly create the invoice number.
• The description text (products, services, consulting...) that will appear on the customer invoice
• In the Debit account, enter the customer account number
  It is important that the customer number complies with certain requirements: see how to correctly create the customer number.
• In the Credit account, enter the counterpart (Sales account, Consulting or other)
• Enter the amount
• In cases subject to VAT, enter the VAT Code with the applicable VAT rate. See Print invoices and VAT management.

If you are subject to VAT under the balance rate or flat-rate regime with the cash-based system, you must record the invoice issuance to the customer and its accounting registration separately, for the following reasons:

1. Invoice to be sent to the customer:
   It must show a normal commercial VAT rate (e.g., 8.1%), as required by tax regulations.
2. Accounting of the invoice:
   It must instead be recorded in accounting with the effective balance rate (e.g., 6.2%), using the corresponding VAT code (e.g., F1).

This approach is essential to ensure that the VAT paid corresponds to the applicable reduced regime, while still maintaining a formally correct invoice for the customer.

Issuing the invoice to the customer

To issue the invoice to the customer, proceed as follows:

In the Accounts Table:

• Create a customer sub-account with the profit center CC3 (example: ;10001 for customer XX)
• In the  Address view, enter all customer data.

In the Transactions table:

• In the Date column, enter the invoice issue date.
• In the Invoice column, enter the invoice number.
  It is important that the invoice number complies with certain requirements: see how to correctly create the invoice number.
• In the Description column, enter the description that should appear in the invoice details.
• In the Amount column, enter the amount
• The Debit and Credit columns must remain empty.
• In the VAT Code column, type the code V81 in square brackets  [V81]. 
  VAT codes in square brackets do not generate any VAT entry.
• In the CC3 column, indicate the profit center number without semicolon (e.g., 10001). 
  It is important that the customer number complies with certain requirements: see how to correctly create the customer number.

Since there are no accounts in the Debit and Credit columns, the invoice creation entry will not be recorded in accounting.

Recording the invoice with VAT balance rate

When recording an invoice subject to VAT with a balance rate in accounting, it is sufficient to proceed as with a normal entry, indicating the accounts in the Debit and Credit columns and entering the VAT code corresponding to the balance rate (e.g., F1).

Two recording systems can be used to register the invoice with the balance rate:

• Recording with split
  In the VAT codes table, VAT percentages have been assigned to balance rate VAT codes. In the transactions table, by entering the balance rate VAT code (e.g., F1), the program automatically enters the corresponding VAT percentage (e.g., 6.2) and the VAT amount.
• Recording without split, by entering the balance rate VAT code (e.g., F1), percentage and amount are not entered. At the end of the period, the specific extension for calculating balance VAT is used. 
  Based on the rate defined in the extension dialog, the program:
  • Identifies all entries with balance rate VAT code.
  • Automatically calculates the VAT due for the reporting period.
  • Totals the amounts on a periodic basis (e.g., monthly, quarterly, yearly).

要在发票中输入折扣或返利，请添加新行并输入：

• 发票日期。
• 发票编号。
• 折扣或返利的摘要。
• 借方和贷方列中的账户。与销售业务相比，倒转账户很重要。
  当客户/供应商明细账设置了成本中心，并且有折扣和返利的发生业务时，为了使金额反转，必须将成本中心的符号也反转。
• 如果有增值税，请在增值税代码中加上负号，以便扣除增值税，或者如果使用当前增值税代码进行折扣和返利，则应扣除增值税。

The Banana Accounting procedure for VAT management requires entering the VAT code always on the line where the income is recorded. When accounting is managed based on turnover, the income is recorded when the invoice is issued. 

When subject to VAT using the balance rates or flat-rate method, customer invoices must be issued using the normal rates (e.g., 8.1%). However, the accounting of invoices under the balance rates or flat-rate method involves reduced rates (e.g., 6.2%).

• If the amounts are gross, you can record them based on turnover or on cash received, by entering the VAT code in square brackets.
• If the amounts are net, it is not possible to create and post the invoices at the same time. In this case, it is necessary to manage:
  • The creation of invoices in an accounting file, using the integrated invoicing or with the Offers and Invoices Application
  • The posting of invoices in the accounting file.
    In this case, the creation of the invoices must be handled in an accounting file or with the Offers and Invoices Application, and the posting in a separate accounting file.

Issuing an invoice with balance tax rate and gross amounts

To issue an invoice to customers with the standard VAT rate (e.g. 8.1%), you need to create a customer subaccount with profit centers CC3 (example: ;10001), completing all customer information in the columns of the Address view.

In the Transactions table:

• In the Date column, enter the invoice issue date.
• In the Invoice column, enter the invoice number:
  It is important that the invoice number follows certain rules: see how to correctly create the invoice number.
• In the Description column, enter the invoice details.
• The Debit and Credit columns must remain empty.
  Since there are no accounts in the Debit and Credit columns, the invoice creation entry will not be recorded.
• In the Amount column, enter the amount.
• In the VAT Code column, type the V81 code in square brackets  [V81]. 
  VAT codes in square brackets do not trigger VAT accounting.
• In the CC3 column, enter the customer account, without semicolon (e.g. 10001). 
  It is important that the customer number follows certain rules: see how to correctly create the customer number.

Posting an Invoice with Balance Rate and Gross Amounts

When recording the invoice in the accounting, to post it using the VAT balance rate, you must enter the transaction as usual, also entering the accounts in the Debit and Credit columns and the VAT code of the balance rate:

• If the VAT breakdown method is used, enter the VAT code for the balance rate (e.g., F1). In this case, the VAT Codes table includes the VAT rates for the balance. In example F1 corresponds to 6.2%.
• If the non-VAT breakdown  method is used, enter the VAT code without rate (e.g., F1). In the VAT code table, the balance rate codes do not have rates.

To post the invoice using the balance rate, it is necessary to create in the Accounts table:

• A customer sub-account using balance sheet accounts.
• Enter the date and description in the corresponding columns.
• In the Debit column, enter the customer account (e.g., 10001).
• In the Credit column, enter the income account.
• In the Amount column, enter the amount.
• In the VAT Code column, type the VAT code for the balance rate (e.g., F1)

In the printout of invoices integrated in accounting, the total VAT amount corresponds to the sum of the individual VAT transactions that make up the invoice. Since the individual VAT transactions are rounded to the nearest cent, there may be a difference compared to the VAT calculated on the total invoice amount. 

To better understand, let's consider the following example: 

• Row 1: 8.1% of CHF 187.33 = Rounded: CHF 14.04
• Row 2: 8.1% of CHF 875.00 = Rounded: CHF 65.76
• Total: 8.1% of CHF 1064.88 = Rounded: CHF 79.80

The invoice shows a VAT amount of CHF 79.80 instead of CHF 79.79 (amount calculated directly on the total of 1064.88). In fact, the amount of CHF 79.80 corresponds to the sum of VAT individually calculated for each item (CHF 14.04 + CHF 65.76). 

This logic is adopted to avoid discrepancies between the VAT amounts recorded in accounting and those shown on the invoice. In this way, the total VAT in accounting matches the one printed on the invoice.
