Shelflane

Digitize and monetize retail promotional space.

Shelflane product interface

Shelflane replaces the black book and the spreadsheet in the back office of SPAR stores. Every gondola end, FSU, crate stack, fridge, and impulse display becomes a bookable, billable asset with an owner, a rate, and an expiry date.

Store owners see exactly which supplier is paying for which space, what has been invoiced, and which placements expire this week. Nothing stays on the floor unpaid, nothing gets double-booked, and payment disputes end because the record is unambiguous.

Shelflane is live inside real SPAR franchises today, built and operated by Cedar, and expanding store by store across franchise networks.

The problem

SPAR stores lose revenue and face payment disputes due to poor tracking of promotional space. Black books and spreadsheets create inefficiency and missed opportunities.

The answer

Shelflane provides a single system to manage placements, supplier agreements, invoices, and expiries. Store owners can book placements, track payments, and ensure displays only stay up for paid periods.

What it does

  • Placement inventory

    Every promotional asset in the store is digitized with its location, rate, and availability, turning floor space into a managed portfolio.

  • Supplier agreements

    Terms, rates, and durations for every supplier deal live in one system instead of a black book and memory.

  • Automated invoicing

    Booked placements generate invoices automatically, so billable space never slips through unbilled.

  • Expiry enforcement

    Alerts fire when placements lapse, so displays come down when the paid period ends rather than living rent-free.

  • Multi-store management

    Franchise groups run several stores from a single account, with per-store visibility and consolidated reporting.

  • Dispute-proof records

    A complete history of who paid for which space and when, ending the payment arguments that plague promotional deals.

How it works

  1. 1

    Map the store

    Digitize every promotional asset with its location and rate card.

  2. 2

    Book placements

    Assign suppliers to spaces with agreed rates and durations.

  3. 3

    Invoice and track

    Invoices generate from bookings, and payment status is visible at a glance.

  4. 4

    Enforce expiries

    When a paid period ends, the system flags it so the space is re-sold, not given away.

Who it serves

  • Store owners

    SPAR owners and managers who want promotional space to earn what it is worth.

  • Franchise groups

    Multi-store operators who need consistency and consolidated visibility across sites.

  • FMCG suppliers

    Brands and reps who get transparent terms and proof their paid placements are actually up.

The model

Shelflane is sold as a monthly subscription per store, priced against the promotional revenue it recovers. For most stores the first properly billed gondola end covers the licence, and multi-store franchise deals compound from there.
