Learn how forward-looking teams in logistics & supply chain automat inbox and attachments data extraction using powerful AI-driven workflows
Table of Contents
In logistics, time is money — literally. Every delayed invoice or purchase order (PO) slows down payments, disrupts vendor relationships, and can even stall shipments. Yet, most logistics companies still process these critical documents manually through Gmail attachments — downloading, reviewing, re-keying data, and chasing approvals.
According to McKinsey, finance and supply chain teams spend 30–40% of their time on repetitive document tasks that could be automated. In logistics, where thousands of invoices and POs flow through email each month, this inefficiency compounds into higher costs and compliance risks.
That’s why more logistics leaders in 2025 are turning to AI workflow automation — transforming how invoices and POs are handled, from Gmail inbox to ERP system, with minimal human intervention.
The Problem with Manual Processing in Logistics
- Volume overload: A mid-sized logistics firm may receive 5,000+ invoices and POs per month, especially during seasonal peaks.
- Diverse formats: Supplier invoices arrive as PDFs, Excel sheets, or even scanned bills of lading — no standardization.
- Costly delays: Manual review slows down payment cycles, hurting supplier relationships and risking late fees.
- Error risk: Hand-entered amounts or PO mismatches create downstream reconciliation headaches.
Manual processing simply doesn’t scale.

Real-World Impact: Faster, Cheaper, Safer
One Zenphi logistics customer handling thousands of supplier invoices monthly reduced their invoice cycle time by 70%, cutting processing from days to hours. By flagging mismatches automatically, they avoided costly payment errors — and by accelerating approvals, they kept freight moving without delays.
Key benefits for logistics teams:
- 70% faster cycle times → suppliers paid on time, shipments cleared faster.
- Fewer errors → automatic data extraction reduces manual entry mistakes.
- Better compliance → every invoice and PO stored securely with audit trails.
- Scalability → workflows easily handle seasonal surges in documents.
Why Gmail Attachments?
For logistics companies, Gmail is often the front door of document exchange. Freight forwarders, carriers, and customs agencies all rely on email for sending invoices, POs, and shipping documents. Automating inbox workflows at this entry point ensures that nothing gets lost or delayed in the inbox
The Bottom Line
Manual invoice and PO processing is a bottleneck logistics companies can’t afford. By combining Gmail with AI workflow automation, logistics teams can eliminate inefficiencies, cut costs, and build stronger supplier relationships.
Zenphi was built to help logistics leaders operationalize AI quickly, safely, and at scale. Start with invoice and PO automation, then expand across your supply chain workflows.
