No app. No paper. SUMWARE mirrors the cart to the customer's phone in real time while the POS scans. Forgot the loyalty card? The CRM finds them again. Not a customer yet? Signup and signature happen on their own phone, straight into the CRM, with no paper involved. The digital receipt is built into SUMWARE from day one, no external provider, no lock-in. Years later, that same receipt is the starting point for every return, warranty extension, user manual, and the next purchase. The receipt is the customer experience platform.

The digital receipt on the customer's phone is a customer experience platform in its own right, far more than a greener version of the paper receipt: built into SUMWARE, with no external provider and no PII stored on our side. The features below span the arc from first onboarding to a repeat purchase three years on. - Live cart on the customer's phone ### Every scan shows up on the phone instantly. While the cashier scans, the cart builds up in real time on the customer's phone. One WebSocket connection to the POS, zero delay, no manual refreshing. Line by line, with discounts, taxes, and a running subtotal. - QR code instead of an app ### Scan the QR. The browser opens. Done. The customer scans a QR code at the POS, and the receipt opens in their regular mobile browser. No app to download, no account to create, no Apple or Google required. The barrier is zero, and the receipt is still fully digital. - Forgot the card? The CRM remembers ### A name, part of an address, or a birthday is enough. Customers who left their loyalty card at home are found again through the CRM integration, by name, partial address, or date of birth. Loyalty points, discounts, and vouchers apply immediately, and nobody has to re-enter their details at the POS. - Alias card as a stand-in ### Alias today. The real card again tomorrow. SUMWARE manages placeholder barcodes for loyalty cards. Customers without their card get an alias card with a unique barcode and use it to identify themselves next time. The customer number in the CRM stays unchanged: every alias card ultimately points to the same regular customer. - GDPR onboarding at the POS ### A new customer in 60 seconds, on their own phone. New customers fill in the signup form on their own phone: address, date of birth, consents, all typed by the customer. No awkward typos in complicated names, no paper, no re-keying. The form goes straight into the CRM, and the customer enjoys the loyalty benefits on that very same purchase. - Signature on their own screen ### Sign by touch, no pad at the POS. Loyalty signup, invoiced sale, or rental contract: the customer signs with a finger on their own phone. No hardware investment in signature pads, no shared stylus. The signature lands directly on the matching receipt or on the CRM signup form. - Digital receipt, no app download ### A PDF in the browser. Save it anywhere. After checkout, the customer gets the receipt as a PDF right in the browser: save it to the photo gallery, email it, add it to Apple Wallet or Google Drive, whatever the customer is used to. No proprietary format, no walled garden. - Your own platform, no provider lock-in ### The receipt lives in SUMWARE, not in a third-party app. The digital receipt is delivered straight from the SUMWARE platform, with no dependency on an external receipt provider, no third-party licenses, no shared customer data. Every extension (loyalty push, app switch, manufacturer services) stays in your hands. - Returns straight from the receipt ### One click. The sales associate has everything. Years after the purchase, the digital receipt still proves what was bought. The customer starts a return or exchange right from the receipt, and store staff see the line item, date, store, and original price without digging through archives. - Self-service warranty extension ### Extend the warranty without a single call. Manufacturer warranties are activated or extended directly from the digital receipt. Serial number, purchase date, and retailer are already on the receipt, and the customer clicks through on their own, no service hotline involved. - User manuals and care instructions ### The manual for every item, one tap away. Every line on the receipt links to its manual, data sheet, and care instructions. No hunting through manufacturer websites, no crumpled leaflet. The customer opens the PDF from the receipt, even three years later. - Stock check and reorder ### "Do you still have these pants?" Live from the receipt. From any receipt line, the customer checks whether an item is still available: in their size, at their store, or online. If yes: reorder right away. If no: suggestions for comparable models. The old receipt becomes a living upselling platform. - Park the cart and hand it over ### From the phone back to the POS, via QR. When a customer switches from self-service back to a staffed POS, SUMWARE parks the cart and issues a QR code. The POS scans it, takes over the cart unchanged, and completes the sale. No double scanning, no lost data. - SUMWARE never stores personal data ### PII stays in the CRM. We keep only the number and the benefit. SUMWARE itself never holds names, addresses, or birth dates; that data stays in your CRM. The platform manages only the customer number, status, and linked benefits. A GDPR right-to-be-forgotten request comes down to a single API call, with no leftover crumbs across the store network. - ### Ready to turn receipts into lasting customer relationships? We demo SUMWARE Customer Engagement live on your assortment, from the QR scan at the POS to a repeat purchase from a three-year-old receipt. No obligation, in 60 minutes.
