2. Detailed Natural-Language Product Prompt

Create a flexible receipt-building and receipt-automation platform for businesses.

The platform should allow users to create multiple receipt types, including sales receipts, payment receipts, tax receipts, tax invoices, refund receipts, exchange receipts, subscription receipts, service receipts, donation receipts, deposit receipts, and custom receipts.

The system must provide a visual receipt editor with drag-and-drop functionality. Users should be able to add, remove, hide, show, reorder, resize, rename, group, and customize every receipt element. Each field should be independently configurable.

Every receipt field must support at least the following visibility states:

  1. Always visible.

  1. Visible only when data is available.

  1. Hidden.

  1. Visible only for selected receipt types.

  1. Visible only for selected customer types.

  1. Visible only for selected countries, regions, tax jurisdictions, stores, or sales channels.

Users must be able to move fields to different areas of the receipt. The available areas should include the header, seller information, customer information, transaction details, line items, discounts, taxes, totals, payment information, shipping, legal and compliance information, returns and refunds, notes, and footer.

Users should be able to rearrange both individual fields and entire sections. The editor should support drag-and-drop ordering, moving fields up or down, changing field alignment, placing fields side by side, and switching between single-column, two-column, three-column, table, stacked, inline, and card layouts.

The user must be able to select a receipt size from common predefined formats. Include 58mm and 80mm thermal receipts, A6, A5, A4, US Letter, responsive digital receipts, email receipts, PDF receipts, and mobile receipts. Also provide a custom-size option where users can specify width, height, measurement units, margins, padding, and page orientation.

The receipt editor should allow users to customize branding and visual presentation. Customization options must include business logo, colors, fonts, font sizes, font weights, alignment, spacing, dividers, borders, backgrounds, icons, images, watermarks, page margins, footer design, header design, and accessibility settings.

The platform must support custom fields. Users should be able to create text, number, currency, date, time, date-and-time, dropdown, multi-select, checkbox, radio button, URL, email, phone, image, barcode, QR code, calculated, signature, and long-text fields.

Each custom field must support configuration options such as required, optional, read-only, staff editable, customer editable, automatically calculated, conditionally visible, imported from an integration, and included only in selected receipt templates.

The platform should include a complete standard receipt field library.

The header field library should include receipt title, logo, business name, business address, business phone, business email, website, receipt number, receipt date, receipt time, document status, original receipt reference, and receipt version.

The seller field library should include legal business name, trading name, business registration number, tax registration number, industry license details, store name, store address, register ID, terminal ID, cashier, salesperson, sales channel, and seller entity.

The customer field library should include customer name, company name, customer address, billing address, delivery address, email, phone, tax ID, account number, loyalty number, purchase order number, customer type, and consent status.

The transaction field library should include transaction ID, order number, sale date, fulfillment date, service period, currency, exchange rate, payment terms, location of supply, and fulfillment method.

The line-item field library should include product name, product description, SKU, barcode, GTIN, quantity, unit of measure, unit price, price type, gross amount, item discount, item tax, net amount, serial number, lot number, batch number, expiration date, warranty information, subscription period, employee or service provider, project code, item category, country of origin, custom attributes, and backorder status.

The discount field library should include list price, customer-specific price, promotional price, coupon code, loyalty discount, volume discount, bundle discount, contract discount, employee discount, manual discount, discount reason, discount subtotal, and discount allocation.

The tax field library should include tax-inclusive or tax-exclusive status, tax jurisdiction, tax type, tax rate, tax code, line tax amount, tax subtotal by rate, exemption status, exemption reason, exemption certificate number, reverse-charge indicator, zero-rated indicator, tax rounding, tax registration region, and special taxes.

The totals field library should include subtotal, total item discounts, order-level discount, shipping charge, handling charge, service charge, gratuity, surcharge, deposit, store credit, gift card amount, tax total, total before payment, amount paid, amount due, change due, rounding adjustment, grand total, and savings total.

The payment field library should include payment method, payment amount by method, card brand, masked card number, authorization code, payment transaction ID, payment status, payment date and time, bank transfer reference, check number, gift card number, voucher number, financing details, deposit applied, refund amount, refund method, payment terms, and balance due.

The shipping field library should include shipping method, carrier, tracking number, delivery address, pickup location, expected delivery date, actual delivery date, delivery confirmation, package count, shipping tax, and delivery instructions.

The legal and compliance field library should include legal invoice identifier, fiscal device number, fiscal signature, QR code, barcode, government verification URL, digital signature, audit trail ID, electronic reporting status, government submission ID, submission timestamp, privacy notice, terms and conditions, consumer rights notice, age verification record, and regulated product license data.

The returns and refunds field library should include return policy, return-by date, refund eligibility, original receipt reference, returned item, return quantity, return reason, refund amount, restocking fee, exchange item, store credit issued, refund approval, refund status, product condition, and warranty claim number.

The footer and communication field library should include thank-you message, customer service message, download link, delivery channel, email subject, email body, SMS message, attachment, language, accessibility format, delivery status, resend option, and communication log.

Every field should have an automation configuration panel. The available automation methods should include:

  • Always automated.

  • Automatically populated when data exists.

  • Manually entered.

  • Manually overridden.

  • Automatically calculated.

  • Imported from an integration.

  • Generated by an AI extraction system.

  • Generated by a rules engine.

  • Generated by a workflow.

  • Approval required before display or processing.

The system should allow users to choose the source of each field. Supported sources should include point-of-sale systems, ecommerce platforms, CRM systems, ERP systems, accounting software, inventory systems, product catalogs, tax engines, payment gateways, bank feeds, shipping providers, warehouse systems, loyalty platforms, subscription platforms, government fiscalization services, email providers, SMS providers, customer portals, APIs, webhooks, CSV imports, OCR, AI extraction, and manual entry.

Users should be able to build conditional rules. Examples include:

  • Display the customer tax ID only when the customer is a business.

  • Display tax exemption information only when the customer is tax exempt.

  • Display shipping information only when the order requires delivery.

  • Display a tracking number only after shipment.

  • Display payment terms when the transaction is unpaid or partially paid.

  • Display a refund section only for refund receipts.

  • Use a different tax calculation based on the destination.

  • Use a different receipt format based on the sales channel.

  • Use a different logo based on the seller entity.

  • Require manager approval for discounts above a selected threshold.

  • Require age verification for restricted products.

  • Send a digital receipt when the customer declines a printed receipt.

  • Add a legal notice based on product category or jurisdiction.

  • Show loyalty savings when a loyalty account is attached.

  • Show the original receipt reference when processing a return or exchange.

The system should support calculations for subtotal, discounts, taxes, shipping, service charges, tips, surcharges, deposits, store credit, gift cards, amount paid, amount due, change due, rounding adjustments, grand total, savings, profit margin, commissions, and refund amounts.

The platform should include integrations for POS, ecommerce, CRM, ERP, accounting, inventory, payment processing, tax calculation, shipping, loyalty, subscriptions, banking, government reporting, email, SMS, cloud storage, and analytics.

The platform should support OAuth, API keys, webhooks, REST APIs, GraphQL APIs, CSV imports, scheduled synchronization, and manual uploads.

Receipt generation should be triggered by events such as order creation, payment authorization, payment capture, payment failure, fulfillment, shipment, delivery, receipt generation, printing, emailing, downloading, refund request, refund approval, refund completion, inventory updates, customer profile changes, tax status changes, payment settlement, and chargebacks.

The system should support automated actions including populating a field, calculating a value, displaying or hiding a field, moving a field, changing a template, applying a tax rule, applying a discount, generating a barcode, generating a QR code, generating a PDF, generating HTML, generating XML, printing, emailing, sending SMS, sending push notifications, updating a CRM, updating accounting records, updating inventory, creating a refund, issuing store credit, submitting information to a tax authority, requesting approval, creating an audit record, flagging an exception, starting reconciliation, and exporting data.

The platform should include validation and error handling. It should validate required fields, data types, tax calculations, currencies, unique receipt numbers, payment totals, refund amounts, customer tax IDs, and jurisdiction-specific requirements.

The system should detect duplicate receipts and identify inconsistencies such as a payment total that does not equal the receipt total, an incorrect tax amount, an invalid tax exemption, a refund greater than the original payment, or a missing required compliance field.

The platform should support roles and permissions. Administrators should control templates, integrations, tax settings, numbering, and user permissions. Managers should approve discounts, refunds, and exceptions. Staff should create transactions and make permitted edits. Customers should view or download receipts and manage their communication preferences.

Sensitive data must be protected. Card information should be masked. The system should support role-based permissions, encryption, audit trails, data retention rules, privacy controls, customer data export, and customer data deletion.

The system should generate printed receipts, PDFs, HTML receipts, email receipts, SMS receipts, mobile receipts, customer portal receipts, tax authority documents, accounting exports, ERP exports, CSV files, JSON, XML, and API responses.

The user interface should include:

  1. A template library.

  1. A drag-and-drop receipt editor.

  1. A field library.

  1. A properties panel.

  1. An automation panel.

  1. A conditional rules builder.

  1. A data source selector.

  1. A live receipt preview.

  1. Desktop, tablet, mobile, thermal, and print previews.

  1. A test-data mode.

  1. A validation panel.

  1. A version history panel.

  1. An integration settings area.

  1. A publishing and activation control.

  1. A receipt analytics dashboard.

Users should be able to save multiple templates, duplicate templates, archive templates, assign templates to stores or channels, create draft versions, test templates, publish templates, roll back to earlier versions, and assign effective dates.

The result should be a modular receipt platform where every receipt element can be turned on or off, automated, manually entered, calculated, conditionally shown, moved to another location, styled independently, connected to a data source, and included in one or more output formats.

Success Criteria

The platform is successful when a user can:

  • Build a receipt without coding.

  • Select any standard receipt field.

  • Add custom fields.

  • Turn every field on or off.

  • Move fields and sections freely.

  • Configure field automation.

  • Connect fields to external data sources.

  • Build conditional rules.

  • Create calculated fields.

  • Select or define receipt dimensions.

  • Preview receipts in multiple formats.

  • Validate the receipt before publishing.

  • Generate receipts automatically after a transaction.

  • Deliver receipts through multiple channels.

  • Maintain compliance, security, and auditability.

The core design principle is:

Every receipt element should be configurable, movable, conditionally visible, automatable, manually overrideable, connected to a data source, and available across multiple receipt formats and delivery channels.
