Customer Display & Digital Receipt is a build-to-order extension for Microsoft Dynamics 365 Business Central that modernizes the moment of checkout for retailers and restaurants. It does two jobs at once: it drives the customer-facing second screen at the till — showing each line item, running total, your branding and promotional or upsell messaging — and it replaces the paper receipt with a branded digital receipt delivered by email, SMS or scannable QR code. Crucially, the receipt flow doubles as a clean, auditable marketing opt-in: when a customer chooses to receive a digital receipt, their explicit consent is captured and written back into Business Central.

This is not an instant AppSource download. ECOSIRE builds the extension to fit your environment, installs it as a per-tenant extension on your Business Central tenant (cloud or on-prem), and supports it after go-live. The app is written in the AL language using table and page extensions on the relevant Sales and POS documents, event subscribers (OnAfterPostSalesDoc / OnAfterFinalizePosTransaction-style hooks) to trigger receipt rendering, and the BC job queue to dispatch email/SMS asynchronously so the checkout lane never blocks. New tables store consent records with timestamp, channel and source for GDPR/CAN-SPAM auditability.

Outbound delivery uses your chosen email connector and a configured SMS gateway (Twilio by default, or your provider) called over its REST API. Consent and receipt data are exposed through the BC REST/OData v4 API so they can flow to Dataverse and the Power Platform for marketing automation. Dedicated permission sets scope who can configure messaging and view consent. The customer screen supports an on-screen tip prompt and signature capture where your hardware allows. You get the source, documentation, and a named ECOSIRE engineer for the build and beyond.
