Challenge
Multi-carrier setup friction
Billing cycles were not slow because of one particular step — they were slow because the entire workflow was fragmented. Everstox operates a multi-warehouse, multi-carrier environment where data arrives in various formats and frequencies.
Pain points
- Data silos: Shipment data lived in various carrier portals, internal tools, spreadsheets, and email threads.
- Inconsistent invoice timing: Carrier invoices arrived in different formats and on different schedules.
- Closed-book pricing complexity: Customer-specific margins were applied manually, requiring significant operational effort, becoming more challenging with every additional customer rate card.
“Senvo reduced our billing cycles from weeks to just a few days. By streamlining carrier invoices across providers, finance finally has a clear, reliable process.”

Solution
Data-agile billing engine
Senvo became Everstox's billing engine, connecting the full loop from carrier invoices to customer invoices, regardless of where the goods were fulfilled.
- Direct carrier connectivity: Senvo connects directly to carriers. No matter how many service providers Everstox uses, shipment and invoice data is pulled and standardized across all carriers and accounts.
- Rapid onboarding of data streams: The platform is built to ingest and adapt to different sources. Adding new warehouses, carriers, or service providers is fast, keeping onboarding smooth as Everstox grows.
- Continuous AI-audits: Invoices are audited immediately and discrepancies are flagged automatically, supporting Everstox's promise of accurate, controlled billing.
- Autonomous customer rate card management: Customer-specific pricing and margins are centralized. Everstox can manage and update rate cards directly in the Senvo platform, maintaining flexibility without operational overhead.
- Accurate outgoing invoices: Shipments flow through the rate engine and are priced using merchant-specific rate cards, producing ready-to-send invoices instantly.
