# Alibris audit profile, Vortex IQ

> What the Vortex IQ Alibris health audit checks: Alibris: FTP Feed Health, Listing Visibility & Cross-Channel ISBN Leak

**[Nerve Centre KPIs](/nerve-centre/kpi-cards/alibris) · [Audit Profile](/nerve-centre/kpi-cards/alibris/audit) · [Sentiment Settings](/nerve-centre/kpi-cards/alibris/sentiment)**

Alibris is a used / rare-book reseller marketplace served entirely over plain FTP (Pure-FTPd at pub.alibris.com - AUTH TLS supported but not required, and the existing CloudHub bridge connects without it). Audits cover FTP connectivity + feed-cycle health, listing visibility (suspended, pending, stale, missing-ISBN), order fulfilment SLA (the seller-rating signal that drives Alibris account standing), pricing / margin watch on rare titles, and cross-channel ISBN comparisons against AbeBooks + Amazon book listings to surface drift, missing-on-Alibris ISBNs, and channel-mix imbalance for book-trade merchants.

## What this audit checks

### Authentication & connectivity

* Plain FTP login on pub.alibris.com:21 succeeds (220 -> 331 -> 230)
* Optional AUTH TLS upgrade, when configured, negotiates cleanly (no fallback to plain after merchant opted in)
* Passive-mode data channel opens on the merchant's egress
* download/ + upload/ folders readable / writable for the merchant's username
* Time skew between merchant clock and Alibris server \<5 min

### Listing-feed health

* Last successful /upload/listings drop \<48h (any older = feed blind)
* Failed batches in /download/acks (any > 0 = rows Alibris rejected)
* Top error patterns clustered from inbound ack files (drives 'fix once' bug list)
* ISBN coverage \<90% (untracked listings can't cross-reference AbeBooks / Amazon)
* Stale listings >180d no update >10% of catalogue
* Suspended / pending listings >0 (direct revenue blocker)

### Order-feed health

* Inbound /download/orders file lag >12h (probable upstream incident)
* Pending dispatch >2x 30D average (back-office backlog)
* Avg time to process >24h
* Late dispatches past dispatch\_due\_by >5% of 30D orders (account-standing risk)
* Cancellation rate >3%
* Return rate >5% (book-trade tolerates some, watch for grading drift on used stock)

### Cost & efficiency

* Commission paid % of revenue drift vs prior 90D
* Avg dispatch hours rising trend (fulfilment cost creep)
* Per-condition margin: like\_new / very\_good vs acceptable mix shift
* AOV drop with no volume drop (mix shift to lower-condition stock)

### Cross-channel: leak vs AbeBooks + Amazon (the killer area)

* ISBN drift - same ISBN, Alibris vs AbeBooks vs Amazon price delta >15%
* Top-50 AbeBooks / Amazon book-revenue ISBNs not listed on Alibris (cheapest revenue lift)
* Alibris price >15% below merchant's own DTC list on like\_new / very\_good first editions (margin erosion)
* Channel mix anomaly: Alibris share of book-trade revenue dropping >25% WoW vs sibling book marketplaces
* Outbound feed cycle desync: same SKU updated on AbeBooks but no Alibris /upload/listings drop in 7d
