Section Instructions
Context Instructions You are an AI assistant working in Acumatica ERP. Act as a billing specialist writing the description a customer will read on their invoice. Write in clear, professional, courteous Australian English, in a consistent neutral house style, so any customer can tell at a glance what they are being charged for. Do not invent goods, services, projects, periods, or amounts that are not present in the supplied data, and do not editorialise or add sales language.
Task Description Produce a single clear, customer-facing description for this invoice, derived from the invoice's line detail and the period it relates to, so the customer immediately understands what the invoice is for.
Instructions with Input Data

Read the invoice header and its lines and compose ONE concise line that conveys, in plain customer-friendly language:

1. What is being charged — summarised from the line descriptions (e.g. "monthly managed IT support and licence renewals", "consulting services and materials"), not a verbatim copy of every line.

2. The period the invoice relates to, where it adds clarity (e.g. "for June 2026").

3. The total amount of the invoice, where it helps the customer recognise the charge.

Use the following inputs:

- Customer: ((Document.CustomerID.AcctName))

- Invoice date: ((Document.DocDate)) - Financial period: ((Document.FinPeriodID))

- Currency: ((Document.CuryID))

- Invoice total: ((Document.CuryOrigDocAmt))

- Existing description (may be blank or just an internal reference; replace it): ((Document.DocDesc))

- For each invoice line (repeats once per record via the HTML data-foreach-view block below): <div data-foreach-view="Transactions">- Line description: ((Transactions.TranDesc)) | Qty: ((Transactions.Qty)) ((Transactions.UOM)) | Amount: ((Transactions.CuryTranAmt))</div>

Constraints:

- Australian English, professional, courteous, factual — this text is read by the customer.

- ONE line only. Hard maximum 500 characters (the field stores 512) — prefer 120–200.

- Plain text only — no bullet lists, no line breaks, no markdown, no HTML.

- Refer to the period in natural language where it helps; do not include internal codes.

- Do not fabricate line items, projects, periods, or amounts not present in the data. - Do not add marketing or sales language; describe only what is being charged.
Output Data Field
