Instructions

๐ŸŸก WRITE ยท creates data โ€” Creates new records (receipts, transactions, postings, invoices, master data). Not idempotent โ€” calling twice may create duplicates. add a receipt Add a receipt into the specified customer account. NOTE: Use this endpoint, to add a receipt without a file!

Endpoint: POST /receipts/add

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dateYesThe receipt's issuing date in format 'YYYY-MM-DD' (e.g. '2017-04-26'). An empty string is not considered a valid date.
typeYesCan be 'invoice inbound' ("Eingangsrechnung"), 'invoice outbound' ("Ausgangsrechnung"), 'credit inbound' ("Eingangsgutschrift ยง 14 UStG"), 'credit outbound' ("Ausgangsgutschrift ยง 14 UStG").
amountYesThe total amount of the receipt, can be negative to indicate a reversed payment (e.g. -12.30). '0.00' is not considered a valid receipt amount.
accountNoIf the receipt shall directly be assigned to a payment account, you can specify its posting account number (e.g. '1200'). If specified, the account must exist as a payment account for the customer. '0' is not considered a valid account.
api_keyNoOptional. The BB customer api_key to act on. Defaults to the BB_API_KEY configured on the server โ€” only set this to target a different customer.
currencyYesAt the moment we accept USD, GBP and CHF. An empty string is not considered a valid currency.
vat_rateNoThe receipt's vat rate (e.g. 19.00 or 0) - may also be an empty string to indicate a non-available or multiple vat rates
counterpartyYesThe counterparty of the receipt, i.e. the invoicing party for type 'invoice inbound' or the recipient for type 'invoice outbound' (e.g. 'Peter Maier'). An empty string is not considered a valid counterparty.
date_deliveryNoThe delivery date in format 'YYYY-MM-DD' (e.g. '2017-04-26'). NOTE: Due to the DATEV compatibility, we cannot accept a delivery date that is after the receipt date! If specified, it will be validated.
invoice_numberYesThe invoice number (e.g. '1231XU23') with a maximum length of 60 characters - may also be an empty string.
creditor_debtorNoIf the receipt shall directly be assigned to a creditor (for type 'invoice inbound') or debtor (for type 'invoice outbound') account, you can specify its posting account number (e.g. '70001'). If specified, creditors/debtors have to be activated for the customer, the creditor/debtor account must exist for the customer and it must be compatible with the specified receipt type. '0' is not considered a valid creditor/debtor.
date_payment_dueNoThe payment due date in format 'YYYY-MM-DD' (e.g. '2017-04-26').
payment_referenceNoThe payment reference id. If specified correctly, the uploaded receipt will match with the corresponding transaction.
link_to_receipt_id_by_customerNoHas to be a valid id_by_customer of another receipt. If specified, both receipts will be assigned to a transaction if one of them is assigned manually.
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate it is not read-only and not idempotent. The description adds context: 'Not idempotent โ€” calling twice may create duplicates' and the ๐ŸŸก WRITE marker, which reinforces the behavioral traits and provides practical guidance.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is relatively concise, with a clear front-loaded warning about write operations and non-idempotency. The content is focused and efficiently conveys the necessary information, though the repetition of 'creates data' and 'not idempotent' could be slightly streamlined.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (14 parameters, no output schema) and the presence of many siblings, the description provides adequate context: it specifies the action, distinguishes the tool from 'receipts_upload', and includes behavioral hints. It does not cover all edge cases but is sufficiently complete for a creation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all 14 parameters. The description does not add additional meaning about parameters beyond the schema details, thus a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The title 'Receipts: add a receipt' and description 'Add a receipt into the specified customer account' clearly state the verb (add) and resource (receipt). It distinguishes itself from sibling 'receipts_upload' by noting this endpoint is for adding without a file.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says 'Use this endpoint, to add a receipt without a file!', providing a clear condition for use relative to 'receipts_upload'. However, it does not address other scenarios or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
