Sync Receipts · Sync Tile

One purchase. A thousand possibilities. One tap at the Tile opens the receipt, adds the stamp and writes the visit to the customer record.

The Tile is concept hardware, the App Clip a concept and Sync Business in development. In the frame: Apple’s official iPhone 18 Pro with iOS surfaces, the Wallet pass and real Sync Business screens. TAKT and its members are fictional; the numbers come from the sample workspace.

Across every location. Every studio, every register, one customer core — as aggregates, never people moving.

  • Verified visits per studio Counted once, after cooldown and checks.
  • Members by home location Where a member joined and where they return.
  • Receipts per register Every sale, its receipt and whether it was opened.
  • Devices and their last tap The last verified interaction per placement.
  • Two locations, side by side This period against the last, every number defined.
  • Aggregates only Never people moving, never a location trail.

Places

  1. Address, opening hours, register — the location shows up in Places at once.

A new location in minutes. Added, assigned, compared.

4 ways in: Wallet, NFC, QR and the receipt

Connect to what you already run. Your till, your booking system, your CRM and your Wallet passes meet in one customer core — through connectors, webhooks, the API and automations.

CRM Booking system
API Webhooks
Connectors Wallet Automations
Connectors, the API and webhooks share one developer contract. Status per connector: Integrations

Built to count correctly. A visit is counted once, after cooldown and checks — at the busiest hour, on a shaky connection, with two people tapping at once.

Idempotent Every write carries an idempotency key: a double tap at the counter never counts twice.

Offline-safe The Sync Business app keeps a pending state when the network drops and confirms once it is back (in development).

Audited Changes to programmes, roles and consent land in the audit log, visible to the roles allowed to see it.

Choose your way in. Ask in plain words, connect your till, or build on the API — the same customer core underneath.

Ask Sync

Questions in plain words, answers from your data with the basis shown. Actions wait for your confirmation.

Sync Impact Concept

Good for business. Better by choice.

After the digital receipt a guest can choose to give — or the business gives per receipt. Pledged, collected and forwarded stay apart; organisations are named only after verification, and no money moves in this phase.

  1. Pledged The guest confirms explicitly.
  2. Collected Only once a payment method actually collects it.
  3. Forwarded To a verified organisation, with a record.
Sync Impact

One platform, three layers. Everything a local business runs on — and the ways customers come in — on one foundation.

  1. 01 Sync OS The Merchant OS: one customer core with the ledger every product writes to, roles per location and the team app at the counter. Sync OS
  2. 02 Sync Studio Disc, pass, stamp card, guest page, stand, e-mail and receipt follow one brand system — designed once, published everywhere. Sync Studio
  3. 03 Sync Intelligence Ask about your business in plain words. Every answer shows where it comes from; actions wait for your confirmation. Sync Intelligence
