Virtual cards for software subscriptions: one card per tool

Why one card per tool

A small agency runs on subscriptions: design tools, hosting, project management, email, analytics, a dozen things that each cost a little every month and together cost a lot. The traditional way to pay for them is one company card number typed into every vendor’s billing page. That works right up until the card is replaced, or someone leaves, or you try to work out which of forty statement lines is the tool nobody has opened since March.

One card per tool gives you four things at once. A kill switch per vendor. A statement where every line has an obvious owner. Containment when a vendor is breached, because the number they hold works nowhere else. And a per-card limit that stops a tool charging more than you agreed without you noticing.

How Capital on Tap virtual cards work

Capital on Tap describes them as instant virtual cards. Each is a complete card: its own 16-digit number, expiry date and security code, issued in seconds from the app or online portal, drawing on the company’s single credit account and limit. The steps on Capital on Tap’s own page are: log in and go to the Cards page, choose “Add a new card”, select the cardholder it belongs to, choose “Virtual card”, set an optional spending limit, and confirm. The card is ready to use immediately and can be added to Apple Pay or Google Pay for contactless payments in person, though it cannot be used at an ATM.

Virtual cards can be created for any cardholder on the account, so a member of staff can have a physical card for travel and a separate virtual card for the one tool they administer. They are also the answer to a lost or replaced physical card: create a virtual one and keep working while the plastic is in the post.

Renewals, free trials and cancellations

Most subscription waste is not the tool you chose; it is the renewal you forgot. Annual plans that auto-renew at a price you did not review. Free trials that need a card up front and quietly convert. Seats that were added for a project and never removed.

With a card per tool, each of these has a mechanical fix. Set the card’s spending limit at or just above the expected charge, so an unexpected renewal at a higher price declines and you get a notification instead of a surprise. For a free trial, create a card for the trial with a limit below the paid price; if you forget to cancel, the conversion fails and the vendor emails you, which is the reminder you needed. When you decide to stop using a tool, cancel in the vendor’s billing settings first and then cancel the card, so that if their cancellation flow is deliberately obscure, the card does the job anyway.

Naming matters. Give each card the vendor’s name and, if useful, the billing cycle, so the Cards page reads as a subscription register. That list, with each card’s limit, is a better record of what the business pays for than any spreadsheet, because it cannot drift out of date: if a tool is being paid for, its card is on the list.

Handling price rises

SaaS vendors raise prices, often with an email that arrives in a shared inbox and is never read. If the card limit was set close to the old price, the first attempt at the new one declines. That is a feature. You now have to make a decision: accept the increase and raise the card’s limit in the portal, negotiate, or leave. What you cannot do is pay the new price for eighteen months without noticing.

A practical limit is the expected charge plus a small margin, enough to absorb a VAT adjustment or a currency movement on a dollar-billed tool but not a plan upgrade. Review limits once a year, ideally when you do the annual budget, so a deliberate increase does not look like an unexplained decline at renewal.

When a vendor charges in dollars

A large share of business software is billed in US dollars, and this is where the choice of card quietly costs money. Most UK business cards add a non-sterling fee of around 3% to every foreign-currency transaction: Amex 2.99%, Barclaycard Select 2.99%, NatWest 2.95%, HSBC 2.99%. Pleo’s cards charge 2.00% / 1.75% / 1.49% by plan depending on plan. On a year of dollar subscriptions that is a real number.

Capital on Tap charges 0% non-sterling transaction fee: “No, the Capital on Tap Business Credit Card charges no foreign exchange (FX) fees.” The statement shows the sterling amount at the Visa rate on the day, with nothing added. Combined with 1% cashback on the spend, a dollar-billed tool on a Capital on Tap virtual card costs measurably less than the same tool on a typical bank card. The FX fee calculator lets you put your own annual dollar spend in and see the difference against each competitor’s fee, and the Revolut comparison covers the multi-currency account alternative, which has an FX allowance rather than a flat zero.

One bookkeeping note: because the vendor charges in dollars and the statement shows pounds, the amount will differ slightly from month to month even when the dollar price is fixed. Set the card limit with a margin for that, and expect your accounting software to show a small exchange difference against a fixed-amount bill.

What happens when you cancel a card

Cancelling a virtual card is permanent and immediate. The next time the vendor attempts to charge it, the authorisation is declined. That is the whole point: the subscription cannot be paid, whatever the vendor’s own cancellation process says.

Three consequences to be aware of. First, the vendor will usually treat a failed payment as a lapse rather than a cancellation: expect dunning emails and, eventually, a suspended account, which is why cancelling with the vendor first is cleaner. Second, anything already pending when you cancel will typically still settle, and refunds to a cancelled card still credit the account, so you lose nothing by cancelling promptly. Third, the points earned on a subscription that is later refunded are cancelled too, since points are cancelled on refunded purchases.

If you only want to pause, freeze the card instead. A frozen card declines everything until you unfreeze it, and keeps its number, so a tool you might come back to does not need re-entering.

Security: no shared card number

The physical company card’s number should be known to as few systems as possible. Every vendor that stores it is a place it can leak from, and when one does, the card has to be replaced and every other vendor updated. Capital on Tap’s own guidance is to create a unique virtual card for each online payment or supplier, so that if one is compromised you cancel that card and create a new one without affecting anything else.

Capital on Tap has also described proactively cancelling and replacing cards whose numbers were targeted by automated guessing attacks; when that happens to a virtual card, the replacement appears immediately in the portal and the old one disappears, and it says the account’s limit, rate and payment dates are unchanged. With one card per vendor, that is one vendor to update rather than forty.

Two things virtual cards do not give you. Section 75 does not apply to business cards, so the statutory protection consumers get on purchases over £100 is not there; disputes with a vendor go through the Visa chargeback process, which Capital on Tap’s FAQ says has time limits and no guaranteed outcome. And a virtual card does not stop an employee with the card details from spending on it; per-card limits and the cardholder terms in the employee cards guide do that.

Bookkeeping: each line matches a vendor

This is the benefit that outlasts the novelty. When every subscription has its own card, the accounting feed shows one recurring line per vendor, on the same day each month, for roughly the same amount, from a card whose name is the vendor’s. Bank rules in Xero, QuickBooks or FreeAgent can then match each line to the right bill or expense account automatically, and the month-end review becomes “is anything new or missing?” rather than “what is this?”.

The Capital on Tap feed syncs every 12 hours to Sage, Xero, QuickBooks, FreeAgent and more and includes card payments, refunds and interest lines. Vendors that issue proper invoices can be set up as suppliers with repeating bills; the card line then matches the bill. Vendors that only send a receipt email can be handled with a bank rule that codes the line straight to the expense account. The accounting sync guide covers connection, reconciliation checks and the common problems. For VAT, remember that many overseas software vendors charge no UK VAT and the reverse charge may apply; that is one for your accountant, but the per-vendor line makes it easy to see which is which.

Cashback follows the spend: 1 point per £1, whichever card it was on, with the points held on the account. How the points show up when redeemed is covered on the rewards page.

Limits per card, card counts and the Visa network

Per-card limits. Each virtual card can carry its own spending limit, set when it is created and adjustable from the Cards page. All cards share the account’s credit limit, so the limits you set are caps within the total, not extra credit. If the company’s limit is modest, a lot of cards with generous individual limits can still be declined when the account total is reached; the credit limit page explains why that total may be lower than the headline suggests.

How many cards. Capital on Tap caps the number of virtual cards that can be created per day, held per cardholder and held across the account. The current figures are on its virtual cards page; for a small business’s subscriptions they are not a practical constraint, but if you plan to create one card per purchase rather than per vendor, check them.

The network. Capital on Tap cards run on Visa, which every online vendor that takes cards accepts. That is worth saying because the Amex business cards, which also offer employee cards, are declined by a minority of vendors, and a subscription that fails at renewal because the vendor does not take Amex is exactly the problem this setup is meant to remove. Interest is not part of this picture if you pay in full; the fees that do apply are listed on the fees and APR page, and the avoid interest guide covers repayment settings.

Suggested setup checklist

1. List every subscription the business pays for, with its billing currency, cycle and current price. Cancel anything nobody claims.
2. In the portal, create one virtual card per vendor, named for the vendor and cycle. Assign it to the person who administers the tool.
3. Set each card’s limit at the expected charge plus a small margin; for dollar-billed tools, allow for exchange movement.
4. Update the card details in each vendor’s billing page and remove the old physical card number from it.
5. Set up bank rules or repeating bills in your accounting software so each card’s line matches automatically.
6. For new trials, create a dedicated card with a limit below the paid price.
7. Add “review virtual card limits and cancel unused tools” to the annual budget process, and “reassign that person’s virtual cards” to the leaver checklist.

Done once, this takes an afternoon. After that the Cards page is the subscription register, the statement reconciles itself, and ending a tool is two clicks: one with the vendor, one on the card. The wider first-hand view of the account is in the review.
