Nightly audits.
Morning shortlists.

Built for independent retail. Each night, autonomous agents sign into your POS, reconcile sales, shipments, transfers and on-hand counts, then email you the five to fifteen items most likely leaking margin — before you open your doors.

How it works

Three quiet steps.
One email before opening.

You keep running your shop. The agent reads the POS you already pay for, cross-checks it, and writes a ranked shortlist you can act on with a cup of coffee.

  1. 01

    Sign in

    You share read-only credentials for your POS dashboard — Square, Shopify POS, Lightspeed, Clover, QuickBooks POS or Vend. The agent uses the same screen you do.

  2. 02

    Reconcile

    Each night it pulls sales, shipments, transfers and on-hand counts, compares them against pricing and timing rules, and isolates the deltas the eye would never catch.

  3. 03

    Shortlist

    Before opening, you receive one email: the five to fifteen items most likely leaking margin, ranked, with a one-line reason per row.

Sample morning email

What lands in your inbox.

Three sample stores, three different shortlists — ranked by margin at risk, each row carrying a one-sentence reason so your walk takes ten focused minutes instead of three untethered hours.

POS coverage

The POSes indie shops already pay for.

Nightwren reads the dashboards you already use. No RFID, no cameras, no router swap, no new vendor in your inbox. Bring your existing credentials; the agent handles the rest from there.

Why Nightwren

Layered on top. Never another dashboard.

Enterprise loss-prevention buys cameras, sensors and deep ERPs for chains. Nightwren drops a thin, owner-friendly reconciliation ring on top of the POS indie shops already pay for — no new screen to learn.

Nightwren

An email before opening.

Owners get a ranked shortlist in plain English, not another dashboard to interpret. Ten focused minutes, then back to the floor.

  • No hardware, no install window
  • POS-only — no customer data leaves the POS
  • Independent retail, designed for one owner
Enterprise L/P

Hardware you didn't budget for.

Cameras, sensors and ERP overhauls that pay back only at multi-store scale. BPA, Petrosoft, PAR Retail, Trigo Vision, Spot AI.

Analyst hire

A part-time shelf-watcher.

What a category analyst does at a chain — except you can't keep one on staff for a 1,200-square-foot storefront.

FAQ

Questions owners ask before turning it on.

Reply to any email — Nightwren is the owner of one tiny shop trying to recover margin with software instead of cameras.

A short note on access & data.

Nightwren uses a read-only staff account on your POS — the same screen view your team would see, scoped per store. Reconciliation runs against sales, shipments, transfers and on-hand counts. We do not request customer payment data, identity, or anything not strictly required to count on-hand versus sold. Credentials revokable in one click; deleted on request.
