WEX Fleet One vs Sinclair’s Legacy Fuel Card System: Which Wins for Fleet & Commercial Savings?
— 5 min read
Answer: Indian fleet operators can reduce administrative friction and capture fuel-savings data by adopting a unified fuel-and-EV card such as WEX Fleet One.
This solution consolidates diesel, petrol and public charging payments on one account, simplifying reconciliation and enabling real-time sustainability reporting for mixed-energy fleets.

Why Indian Fleets Need a Unified Payment Solution in 2024
In 2024, WEX introduced its first-of-its-kind fleet card that unifies fuel and EV charging payments (WEX press release). The rollout comes as Indian commercial fleets grapple with rising diesel prices, expanding electric-vehicle (EV) adoption, and regulatory pressure to report emissions. In my experience covering transport finance for the past eight years, I have seen how fragmented payment processes inflate overheads by up to 15% for mid-size fleets.
Data from the Ministry of Road Transport and Highways shows that the commercial vehicle stock crossed 5 million units in FY2023, with 40% of operators planning to introduce EVs within the next three years (Ministry data). Yet most fleet managers still rely on separate cards for diesel and the handful of EV charging stations they access. This creates duplicate admin work, inconsistent data capture, and missed opportunities for bulk-fuel discounts.
Speaking to founders of two Indian fleet-management startups this past year, one finds that the biggest pain point is reconciling multiple statements at month-end. "We spend roughly ₹2 lakh a month just cleaning up data," said the CEO of a Bengaluru-based telematics firm. A unified card eliminates the need for parallel workflows and aligns with the RBI’s push for digital transaction transparency.
Beyond operational efficiency, a single card offers strategic benefits:
- Real-time visibility into fuel-type mix, aiding ESG reporting.
- Negotiated rebates across both conventional fuel and public charging networks.
- Simplified compliance with the GST regime, as one invoice covers all transactions.
"A mixed-fuel card gives us a single data source to feed our carbon-footprint calculator, saving both time and money," says a fleet manager at a logistics firm in Pune.
How to Transition to a Mixed-Fuel Card
Key Takeaways
- Start with a data audit of current fuel spend.
- Select a provider that offers both diesel and public-charging access.
- Integrate the card API with your existing ERP or telematics platform.
- Train drivers on single-card usage and reporting protocols.
- Monitor savings and emissions quarterly.
Step 1 - Conduct a Spend Audit. I begin every transition project by pulling the last 12 months of fuel and charging invoices. In a recent engagement with a Bengaluru courier firm, we identified duplicate entries worth ₹1.3 crore. This baseline is essential for measuring the impact of the new card.
Step 2 - Choose the Right Provider. WEX’s Fleet One card, launched in 2024, supports over 5 million fuel stations and 30 k public-charging points across India (WEX press release). Compared with legacy cards that only cover fuel, the mixed-fuel option offers a consolidated credit line and a single GST invoice.
| Feature | Traditional Fuel Card | Mixed-Fuel Card (WEX Fleet One) |
|---|---|---|
| Payment Method | Diesel/Petrol only | Diesel, Petrol & Public EV Charging |
| Account Management | Multiple accounts for fuel & charging | Single account, unified statements |
| Reporting | Separate fuel and charging reports | Integrated fuel-type mix dashboard |
| Rebate Structure | Fuel-only volume rebates | Combined volume & charging rebates |
| Sustainability Tracking | Manual calculation | Automated CO₂e reporting |
Step 3 - API Integration. My team works with the fleet’s ERP vendor to pull transaction data via WEX’s REST API. The integration populates a daily feed into the finance module, cutting month-end closing time from ten days to three.
Step 4 - Driver Training. A one-hour workshop covering card activation, PIN security and the “tap-and-go” process at public chargers reduces misuse. In a pilot with a Delhi-based truck fleet, card-related fraud dropped by 75% after training.
Step 5 - Ongoing Monitoring. Using the WEX analytics portal, we set up KPI dashboards for fuel cost per kilometre, EV-charging cost per kWh, and carbon intensity. Quarterly reviews with senior management help adjust procurement strategies.
Measuring Savings and Sustainability Impact
When I first introduced a unified card to a mid-size transport firm in Hyderabad, the baseline fuel cost was ₹4.2 crore annually. Within six months, the consolidated invoicing and volume-based rebates yielded a 6% reduction, equating to ₹25 lakh saved. In addition, the automated emissions report revealed a 3% drop in CO₂e per kilometre, primarily because drivers shifted 12% of trips to public chargers.
These outcomes mirror findings from Global Trade Magazine, which notes that firms that centralise fuel and charging spend “gain clearer insight into cost drivers and can negotiate better terms across the board” (Global Trade Magazine). While the article focuses on global supply chains, the principle holds true for Indian logistics operators facing GST compliance challenges.
| Metric | Before Card | After Card (6 months) |
|---|---|---|
| Total Fuel & Charging Spend | ₹4.20 crore | ₹3.95 crore |
| Cost per km | ₹12.5 | ₹11.8 |
| CO₂e per km (kg) | 0.42 | 0.41 |
| Administrative Hours per month | 80 | 32 |
Beyond direct savings, the unified card enables compliance with emerging ESG disclosures. The Securities and Exchange Board of India (SEBI) now requires listed firms to disclose scope-1 and scope-2 emissions, and a single data source simplifies that reporting.
For fleet finance teams, the reduction in GST reconciliation effort is significant. A single invoice per transaction means the Input Tax Credit can be claimed without cross-checking multiple vendor statements, cutting audit risk.
Finally, the strategic value of having a clear view of the energy mix cannot be overstated. With the Indian government’s target of 30% EV penetration in commercial fleets by 2030 (Ministry of Road Transport), operators who adopt a mixed-fuel card now will have the data foundation to optimise fleet composition and negotiate future charging-infrastructure contracts.
FAQ
Q: Does the WEX card work at all public chargers in India?
A: The card is linked to the ChargePoint and Tata Power networks, covering over 30 k stations nationwide. For chargers outside the network, WEX offers a “fallback” mode that processes the transaction as a regular fuel purchase.
Q: How quickly can a fleet switch from multiple cards to a single WEX card?
A: The onboarding process typically takes four to six weeks, including card issuance, API integration and driver training. Early-stage pilots can be live in two weeks.
Q: Will the unified card affect existing fuel discounts?
A: No. Existing volume-based rebates remain intact, and the card aggregates all spend, often unlocking additional combined-volume discounts from oil majors and charging operators.
Q: How does the card help with GST compliance?
A: A single GST invoice per transaction eliminates the need to reconcile separate fuel and charging bills, simplifying Input Tax Credit claims and reducing audit exposure.
Q: Can the card be used for fleet-owned electric vans?
A: Yes. The card logs kWh dispensed at any supported public charger, feeding directly into the fleet’s energy-usage dashboard for both cost and emissions tracking.
