The best expense management software for small UK businesses in 2026 is Moss. It offers a genuinely free tier for up to 3 users, no per-user pricing as you grow, and fast onboarding without a lengthy sales process. This guide compares five platforms built for cost-sensitive small teams. We cover verified UK pricing, free tiers, and how quickly you can get cards issued and receipts flowing into your books.
We focused on tools that suit a five-to-twenty person business. Look for no lengthy contracts, no forced per-seat fees where avoidable, and setup that takes minutes rather than weeks. We verified every price directly against each provider’s live site in July 2026. We weighted free tiers, onboarding speed and accounting sync over enterprise features most small teams will never touch.
- Best all-round for small teams: Moss - free for up to 3 users with unlimited cards, and no per-user fee as you scale.
- Cheapest transparent pricing: Pleo - published tiers from £9.50/month, so you know the cost before you talk to sales.
- Best if you already bank with Tide: Tide Expense - £5/seat/month add-on, from £27.49/month all-in for a small team.
- Best free card issuing: Wallester - free for up to 300 virtual cards and unlimited seats, but no receipt OCR or accounting sync.
- Watch the per-user creep - card-led tools look cheap at 3 users and expensive at 15, so model your real headcount first.
Best Expense Management Software for Small Business Compared
Prices below are verified from each provider’s live site in July 2026. Free tiers and per-user fees matter most for a small business, more than the enterprise features some of these tools also carry.
| Provider | Best For | Price (from) | Key Feature | Free Tier |
|---|---|---|---|---|
| Moss PICK | Small teams on Xero/QuickBooks | Free; paid on quote | No per-user fee | Yes (3 users) |
| Pleo | Transparent card-led pricing | £9.50/mo | Published tiers | No |
| Tide Expense | Sole traders / Tide customers | £5/seat/mo + account | Bundled with banking | No |
| Wallester | Free virtual-card issuing | Free; from €199/mo | 300 free virtual cards | Yes |
| Expensify | Budget receipt scanning | $5/user (USD) | Unlimited SmartScan | Individuals only |
Moss EDITOR’S PICK
Moss pairs a genuinely usable free tier with a pricing model that never penalises you for hiring, which is exactly what a cost-sensitive small business wants from expense software, and the free plan alone covers real spend before you pay a penny.
Moss’s free plan covers up to 3 users with unlimited physical and virtual cards and up to 20 invoices a month. That’s plenty for a very small team to run real spend before paying anything. Once you outgrow that, paid pricing is a flat platform fee plus a variable fee tied to monthly transaction volume, quoted by module (cards, reimbursements, accounts payable). There is no charge per user, so hiring your fourth or fifth employee does not automatically inflate the bill the way per-seat rivals do.
For a small business already using Xero or QuickBooks, Moss is hard to beat. AI reads receipts and auto-categorises them, approval flows are configurable, and 50+ integrations cover the accounting stack you are likely to run. The catch is that once you’re past the free tier, headline pricing needs a quick call to size. Budget ten minutes for that conversation. If payroll is your next priority, pair Moss with dedicated payroll software rather than expecting an expense tool to run PAYE.
Pleo
Pleo is the pick for a small business that wants to know the exact monthly cost before booking a demo, with published tiers starting low enough for a five-person team to try properly, and pricing that scales predictably as you add each new employee’s card.
Pleo publishes its pricing, which is rarer than it should be in this market. The Starter plan is from £9.50 a month billed annually and includes 3 users with 1 vendor card, an easy entry point for a very small team. Essential steps up to £45 a month (or £39 billed annually) plus £11 per extra user, adding mileage, reimbursements and up to 25 vendor cards. That’s where most five-to-ten person teams will land.
The trade-off is that Pleo has no free tier, and Trustpilot reviews around 3.5 out of 5 flag support response times as the recurring gripe. For a small, card-first team that values predictable, published costs over a completely free plan, Pleo is still hard to beat. If you’re also comparing wider small-business finance tools, our business finance guides cover funding and cash-flow options beyond expense cards.
Tide Expense
Tide bolts lightweight expense cards onto its business account, which makes it the fastest setup on this list if you already bank with Tide and just want simple company cards for a small team, without onboarding onto a completely separate platform or learning new software.
Tide’s expense cards are a £5 per seat a month add-on. Each cardholder gets one physical and up to five virtual company Mastercards, with receipt scanning and per-card spending limits. You need a Tide account to use it. The Free tier costs nothing, while Smart (£12.49), Pro (£27.49) and Max (£69.99) a month include one, two and three free seats respectively before the £5 add-on kicks in.
It is deliberately lightweight, so do not expect the invoice automation or approval depth of Moss or Pleo. Transactions auto-label into accounting categories and sync to your books, which covers the basics well for a small team’s day-to-day spend. If you also take card payments from customers, it is worth understanding how business banking and merchant accounts fit alongside an expense tool.
Wallester
Wallester is a card-issuing platform rather than a full expense suite, and for a small business that mainly needs cheap company cards fast, its free tier is one of the most generous on this list, covering up to 300 virtual cards and unlimited seats at no cost.
Wallester’s free tier is unusually generous for a small team. It covers up to 300 virtual cards, unlimited physical card issuance, and unlimited seats, priced by card-programme volume rather than per user. Paid tiers start from around €199 a month for larger allocations, though the site prices in euros rather than pounds. For a five-person team that just needs cards issued fast, the free tier alone will likely cover you.
Be clear about what it is not. Wallester has no receipt OCR, no native Xero or QuickBooks accounting sync, and no post-transaction approval workflow, so someone still has to reconcile spend manually. If you want a small business’s full expense process with receipts and approvals, choose Moss or Pleo instead. If you specifically want free, high-volume card issuing, Wallester is a strong, honest fit.
Expensify
Expensify is the budget, self-serve choice for a small business that mainly needs fast receipt scanning and simple reimbursements rather than a full corporate-card programme, and individuals can use its core scanning tool for free before you ever pay for a workspace.
Expensify prices in US dollars. The Collect plan is $5 per member a month and Control is from $9 per active member a month, with annual billing discounted. Individuals can use unlimited SmartScan and chat for free, but any business expense-report workflow needs a paid workspace. Because it bills in USD, a UK small business should factor in currency conversion and card FX rather than assuming a flat pound figure.
SmartScan receipt capture is the standout. Collect integrates with QuickBooks Online and Xero, covering the accounting sync most small teams need without cards or heavy approval chains. It suits a five-person team that mainly wants receipts and reimbursements handled cheaply. Expensify has no AppWiki feed and is listed here purely on merit, because small-business buyers expect to see it in any fair shortlist.

How We Picked These Providers for Small Business
We compared five expense platforms against the priorities that matter most to a small UK business: genuine free tiers, no forced per-user penalties, fast setup, and accounting sync, verifying every price directly against each provider’s live site in July 2026.
Our assessment weighted four things for a small-business reader specifically. We looked at free-tier generosity, how transparent the pricing is, whether costs scale per user or stay flat as you hire, and how quickly you can start issuing cards or scanning receipts. Where a provider does not publish pricing, we say so plainly rather than guessing. Expensify has no affiliate arrangement with us and is included purely because small-business buyers expect to see it in any fair comparison, which keeps this list honest.
How to Choose Expense Software for Your Small Business
The right choice for a small business comes down to three things. Consider how many people need cards, whether you can live with per-user pricing, and how fast you need to be up and running. Match the tool to those factors before you look at the price tag.
Choose Moss if your team is 3 people or fewer and you want a genuinely free platform with no per-user fee as you grow. This works especially well if your books are already in Xero or QuickBooks. Choose Pleo if you want published, predictable pricing from day one and don’t mind a low per-user fee once you outgrow the 3 included seats.
Choose Tide Expense if you already bank with Tide and want simple company cards bundled into your existing account rather than a separate sign-up. Choose Wallester if your real need is free, high-volume virtual-card issuing rather than a full expense process with receipts and approvals. Choose Expensify if you mainly need cheap, fast receipt scanning and don’t need corporate cards at all. For a broader view of the whole market, see our full expense management software comparison.
What a 5-Person Team Actually Pays for Expense Software
Here is what a five-person UK small business would realistically pay each month, with everyone holding a company card. We only used providers with figures clear enough to do the maths, based on verified pricing.
On Pleo Essential, a five-person team costs £45 a month for the first 3 users plus £11 each for 2 extra users. That’s around £67 a month, or roughly £61 if billed annually. On Tide, a Pro account (£27.49, 2 free seats) plus 3 paid expense-card seats at £5 each comes to about £42.49 a month, which also buys business banking.
On Wallester, five seats and cards cost nothing, since the free tier covers up to 300 virtual cards and unlimited seats, though you lose receipt OCR and accounting sync. On Expensify Collect, five members at $5 each is $25 a month in USD, before FX. Moss is free for the first 3 users, but a 5-person team is over that cap and needs a quote for its no-per-user paid tier. That tier usually wins once you’re past 6-8 people.
