Rate deck errors causing calls routed at a loss or not billed
Definition
Wholesale voice carriers frequently mis‑manage rate decks (wrong buy/sell rates, missing or outdated destination codes), causing traffic to be routed on unprofitable routes or billed at incorrect prices. This leads to persistent revenue leakage when sell rates are below cost or certain destinations are not billed at all.
Key Findings
- Financial Impact: Industry analyses of wholesale and interconnection margins indicate that routing and rate mis‑alignment can erode 3–7% of interconnect revenue; for a carrier with $100M wholesale voice revenue, this is roughly $3–7M per year.[1][7]
- Frequency: Daily
- Root Cause: Highly fragmented, frequently changing wholesale rate decks from multiple carriers, maintained in spreadsheets and updated manually without centralized governance or automated validation. Lack of real‑time linkage between agreed interconnect rates and the routing/billing engines means errors persist for long periods.[1][2][7]

Financial Impact
$1.2M-$4M annually for reseller (customer billing disputes; compliance failures; revenue leakage on wholesale routes) • $1.2M–$3.5M annually (3–5% revenue loss for CLECs with $50–100M wholesale voice; routes sent to carriers at a loss due to stale/wrong rates) • $1.5M-$4M annually (voice service margin erosion; incorrect interconnect billing; customer refunds)
Current Workarounds
Email-based rate update notifications stored in shared folders; manual entry of rates into billing systems; Excel tabs for different carrier agreements; spreadsheet-based route profitability checks • Excel pivot tables comparing old vs. new rate decks; manual spot-checks on sampled call records; Slack notifications when someone notices a routing anomaly; memory-based route selection avoiding 'known bad' carriers • Excel spreadsheets with manual rate comparisons; WhatsApp/email chains between ops and finance to flag suspected unprofitable routes; ad-hoc Python scripts or VBA macros to cross-check buy vs. sell rates
