The short answer
Fuel cards let drivers pay for approved purchases through a business account. Check the station, pay with the card, keep the receipt and finish the expense record. With Rally, you fund the balance first and submit receipts through WhatsApp.

Never do your expenses again
Rally's AutoMatch agent handles everything for you
Fuel cards let drivers pay for approved purchases through a business account. The business sets up the card and its spending rules. At the station, the driver pays with the card and keeps the purchase evidence. Finance then connects the payment with its receipt or invoice and records the expense.
The money comes either from a balance funded in advance or from a billing arrangement agreed with the provider. Rally's standard published plans are prepaid, so the business adds funds before spending.
That fourth step is what turns a card purchase into a completed business expense. See the Rally expense workflow for the WhatsApp and platform agents together.
The administrator creates or assigns the card, sets the relevant budget and controls, and explains which purchases are approved. For prepaid cards, the business also funds the account.
Give each person clear instructions for receipt submission and a contact for payment problems. Confirm the usual stations and any pay-at-pump terminals before a driver relies on the card for a journey. Card acceptance and purchase approval are separate checks: a merchant may accept Visa while a particular transaction exceeds the company's card limit.
For a team sharing vehicles, decide how a purchase will be associated with the right driver, project or vehicle in your expense process. Do that before the trip, while the responsibility is clear.
| Arrangement | How purchases are funded | What to check |
|---|---|---|
| Prepaid | The business adds money before the card is used | Top-up process, available balance, payment holds and card fees |
| Postpaid | The business pays according to an agreed billing schedule | Approval requirements, payment dates, credit terms and any security requirement |
Rally's prepaid route requires business and representative verification, but no personal credit check or refundable security deposit. Prepaid does not mean there is no upfront funding: you still need money in the balance for approved purchases. Postpaid terms, where offered, require separate approval and may involve credit or security requirements.
A funded balance pays for purchases. A refundable deposit is held as security. A card fee pays for the service. Keep those three amounts separate when comparing costs.
The fuel itself and the card service are separate costs. Check the applicable fuel price, monthly card and account fees, transaction charges, currency charges and any minimum-use conditions.
Rally's prepaid plans charge a flat monthly fee for the cards included, excluding VAT and purchases. Every plan includes the same core card, expense and accounting features; Enterprise plans add account management and rollout support. See current pricing for the plan that covers your card count and use the fuel card quote calculator to work with your own monthly figures.
A card does not automatically make fuel cheaper. Compare the price at the stations you use, plus the applicable fees and any extra distance needed to reach an accepted site.
Payment creates a transaction record. The receipt or invoice explains what was bought. Finance also needs the business purpose and the right allocation for its accounts.
With Rally, the employee can send the document through WhatsApp without downloading a separate expense app or using an additional Rally login for basic submission. The agent helps collect the missing details in the same conversation.
AutoMatch uses the document and payment context to connect them; it does more than read the printed text. In the platform, finance can review outstanding items and prepare the next step. Accounting integrations and exports carry the reviewed data into the supported accounting workflow.
Keep the source evidence your business needs. An account statement is not automatically a suitable tax invoice for every purchase, and a successful card payment does not establish how that expense should be treated for tax.
| What to check | What to do |
|---|---|
| Card status | Confirm the card is active and has not been frozen |
| Available balance | Check enough funds remain, including any temporary authorisation at the pump |
| Spending controls | Ask the account administrator whether the amount or purchase category is allowed |
| Merchant and terminal | Confirm that this location and payment method support the card |
| PIN or terminal error | Follow the terminal guidance and ask the account administrator or support for help |
An unattended pump may request authorisation for more than the final fuel purchase before dispensing. That can affect the available balance temporarily. Keep an approved backup payment process for situations the driver cannot resolve at the station.
If a card is lost, freeze it promptly and report the loss through the business's process. Freezing prevents further authorised use of that card, but the business should still review recent activity.
Permitted purchases depend on the product and the business's controls. Rally cards can support approved fuel and other work expenses, including parking, tolls and supplies. Public charging also depends on the payment method available at the charger.
Company policy determines whether personal purchases are allowed and how they are handled. Do not assume the card can identify every item inside a purchase or make misuse impossible. Clear rules, appropriate controls and review of unusual transactions all matter.
Check country support and currency charges before the trip. Keep the original supplier document alongside the payment, even when the amount settles in a different currency. The business should confirm the accounting and tax treatment of overseas purchases with its accountant.
