The best genuinely free expense management software for UK businesses in 2026 is Moss. It gives up to 3 users unlimited physical and virtual cards at £0/month, with no per-user fee. This guide covers tools with a real free tier or a workable free plan. Not “free trial” software that starts billing after 14 days. You will know exactly what you get for nothing, and where the catch is.
Free expense tools fall into two honest categories. Some have a permanent free plan built for small teams. Others are card-issuing tools that make money on interchange, not subscriptions, so the cards themselves cost nothing. We checked each provider’s live UK pricing page in July 2026. We only cite what is verified there, including where “free” quietly stops.
- Best genuinely free: Moss - £0/month for up to 3 users with unlimited cards and no per-user fee.
- Most generous free cards: Wallester - up to 300 free virtual cards and unlimited seats, priced by volume not headcount.
- Free banking, paid cards: Tide - the business account tier is free, but expense cards cost £5 per seat/month.
- Free for individuals only: Expensify - unlimited SmartScan is free solo, but business workflows need a paid workspace.
- Watch the upgrade trigger - most “free” plans cap users, cards or invoices; check the limit before you build a process around it.
Free Expense Management Software Comparison Table

|---|---|---|---|---|
| Moss PICK | Small UK teams, no per-user fee | Free; paid on quote | Unlimited cards, 20 invoices/mo | Yes – 3 users |
| Wallester | High-volume virtual card issuing | Free; from €199/mo | 300 free virtual cards | Yes – 300 cards |
| Tide Expense | Sole traders already on Tide | £0 account; £5/seat cards | Bundled with Tide banking | Partial – account only |

| Pleo | Transparent card-led pricing | From £9.50/mo | Published tiers, cashback | No |
Moss EDITOR’S PICK
Moss is our pick because its free plan is a real product, not a crippled trial. There is no per-user fee waiting to hit once you start hiring.
Moss’s free tier covers up to 3 users with unlimited physical and virtual cards, plus up to 20 invoices a month, at £0/month indefinitely. That is enough for a small team to run real day-to-day spend, not just a demo. Paid plans move to a flat platform fee plus a variable fee based on monthly transaction volume. Pricing is quoted by module: cards, reimbursements, accounts payable. There is still no per-user charge on paid plans. Growing headcount does not automatically inflate the bill, unlike seat-priced rivals.
The free plan includes AI receipt OCR, auto-categorisation, and customisable approval steps. It also has 50+ integrations, including Xero, QuickBooks, NetSuite, SAP and Dynamics 365. The limit to watch is the 3-user, 20-invoice cap. Cross either one and you need a paid quote; exact paid figures are not published. If your books already run through Xero or QuickBooks and your team is small, Moss is the strongest free starting point. Pair it with dedicated payroll software rather than expecting an expense tool to run PAYE.
Wallester
Wallester’s free tier is the most generous card allowance on this list. But it is a card-issuing platform, not a full expense process, and that distinction matters before you sign up.
The free plan gives you up to 300 virtual cards, unlimited physical card issuance, and unlimited seats. It is priced by card-programme volume rather than per user. Paid tiers start from around €199 a month for larger allocations (Wallester prices in euros, with no GBP rate card). A €999 platinum tier adds a dedicated account manager. For ad spend, contractor cards or embedded card programmes that need volume, the free tier alone often covers a small business indefinitely.
The catch is what “free” does not include. No receipt OCR. No native Xero, QuickBooks or ERP accounting sync. No post-transaction approval workflow. Spend control is pre-set card limits, not manager sign-off after the fact. If you want a real finance team process, Moss is the better free fit. If you specifically need cheap, high-volume card issuing with a developer API, Wallester’s free tier is a strong, honest deal. Businesses comparing card options broadly may also want our business expense cards guide.
Tide Expense
Tide is worth including because its business account has a genuine £0 tier. But be clear-eyed: the expense cards feature people search for is a paid add-on, not part of the free plan.
Tide’s Free account costs £0/month. It gets you business banking, with no expense cards included. Expense Cards are a separate add-on at £5 per seat/month. Each cardholder gets one physical and up to five virtual company Mastercards, with receipt scanning and per-card spending limits. Smart (£12.49/month) includes 1 free seat, Pro (£27.49) includes 2, and Max (£69.99) includes 3. The seat allowance is bundled into the paid account tiers, not the free one.
In practice, “free” with Tide means free banking with card payments visible in your feed. It is not a free way to issue company expense cards. If you already bank with Tide and only need one or two cardholders, £5 per seat is still cheap next to a standalone expense platform. If you need cards from day one at zero cost, Moss or Wallester are the honest free options. Businesses also managing team pay may want our HR software comparison alongside their banking setup.
Expensify
Expensify’s free tier is real but narrow. Unlimited SmartScan and chat for individuals, with no permanent free plan once you need a business expense workflow.
A single user can scan unlimited receipts and use SmartScan for free, indefinitely. That is genuinely useful for a freelancer or sole trader tracking their own spend. As soon as you need shared workspaces, approvals or reimbursement workflows for a team, you move to a paid plan. Collect is $5 per member a month; Control is from $9 per active member a month. Both are billed in USD with no captured GBP figure, so factor in currency conversion when budgeting.
Collect integrates with QuickBooks Online and Xero. Control adds NetSuite, Sage Intacct and Workday. Expensify has no AppWiki feed with us and no affiliate arrangement. It is listed here purely because the free individual tier is genuinely useful for solo UK users, not because we earn from the click. Zoho Expense is another provider worth checking directly. It publishes a free plan aimed at very small teams, but we have not independently verified its current caps, so we are not quoting specific limits here.
What Free Really Gets You (And Where the Limits Are)
Every “free” plan on this list is free for a reason, and it is rarely charity. Understanding why a provider gives something away tells you exactly where the limit will bite.
Moss and Tide’s free tiers exist to get you using the wider platform. They charge once you scale past a small team or need paid features; that is a standard freemium model. Wallester’s free tier works differently. It earns money on card interchange fees every time a card is used. Giving away 300 virtual cards costs it little, and you almost nothing, provided you do not need the accounting sync or approvals it deliberately leaves out. Expensify’s free tier is scoped to individuals specifically, because business use is where the real product value, and the billing, sits.
Watch four practical upgrade triggers. User count: Moss caps at 3. Invoice volume: Moss caps at 20/month. Card programme size: Wallester caps at 300 virtual cards. And whether you need any card at all, since Tide’s free tier has none. Pleo, by contrast, has no free tier at any size, starting from £9.50/month, which at least means no nasty surprise later. Map your actual headcount and invoice volume against these caps before you build a process around a free plan. That way the switch to paid is a choice, not a scramble.
How to Choose Free Expense Management Software
The right free tool depends on what you actually need for nothing: cards, receipt scanning, or just a lightweight way to track team spend. Match the free tier’s real limits to your team size first.
Choose Moss if you have 3 or fewer users, want unlimited cards, and your books run through Xero or QuickBooks. Choose Wallester if your real need is issuing many virtual cards cheaply and you do not need receipt OCR or approvals. Choose Tide only if you already bank there and are happy paying £5 per seat once you need actual expense cards. Choose Expensify if you are a solo user or freelancer who just needs free receipt scanning, not a team process.
If none of the free tiers fit, because you need more than 3 users, cards, published pricing, or cashback, it is worth comparing paid platforms properly. Do not stretch a free plan past its limit. Our full expense management software comparison covers paid tiers including Pleo and Payhawk in detail. It pairs well with our guide to merchant accounts and payment gateways if you also take card payments.
