Best Expense Management Software UK 2026: 8 Compared

The best expense management software for most UK businesses in 2026 is Moss, thanks to a genuinely usable free tier, no per-user pricing, and deep Xero and QuickBooks integration. This guide compares eight leading platforms on verified UK pricing, features, and real-world fit, so you can pick the right one without trawling eight separate pricing pages.

We looked at card-led tools like Pleo and Payhawk, enterprise suites like SAP Concur, budget receipt-scanners like Expensify, and card-issuing platforms like Wallester. We verified every price directly against each provider’s live UK site in July 2026, then assessed features, accounting integrations, and UK compliance so finance teams can shortlist in minutes.

Expense Management Software Comparison Table

Prices below are verified from each provider’s live UK site in July 2026. Card-issuing tools like Wallester look cheapest but lack the accounting sync and receipt OCR most finance teams need.

Moss combines corporate cards, accounts payable, and reimbursements in one platform, with a free tier and no per-user pricing that competitors rarely match.

Moss’s free plan covers up to 3 users with unlimited physical and virtual cards and up to 20 invoices a month, which is enough for a small team to run real spend before paying anything. Paid pricing is a flat platform fee plus a variable fee based on your monthly transaction volume, quoted by module (cards, reimbursements, accounts payable). Crucially, there is no charge per user, so adding staff does not inflate the bill the way it does with per-seat rivals.

Where Moss earns its top spot is depth without complexity. AI reads receipts and auto-categorises them, approval flows and budgets are configurable, and 50+ integrations include Xero, QuickBooks, NetSuite, SAP and Dynamics 365. If your books live in Xero or QuickBooks and you want one tool for cards, bills and expenses, Moss is the strongest fit. The main caveat is that headline paid pricing is not published, so you will need a quick sales call to size it. For payroll-heavy teams, pair it with dedicated payroll software rather than expecting expense tools to run PAYE.

Pleo is the pick when you want to know the price before you talk to sales, with published tiers and a low entry point for small teams.

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. Essential is £45 a month (or £39 billed annually) plus £11 per extra user, adding mileage, reimbursements and approval workflows. Advanced (£109 a month) and Beyond (£219 a month) layer on multi-entity management, HRIS integrations and cashback of up to 0.75%. There is no free tier, but the entry price is low enough for a startup to trial properly.

The trade-off is per-user pricing, which climbs as your team grows, and a Trustpilot record where support response times are the recurring gripe. For a small, card-first team that values predictable, published costs, Pleo is hard to beat. Larger teams should compare the per-user maths against Moss’s flat model before committing.

Payhawk targets finance teams that have outgrown simple tools, with genuine multi-entity consolidation and two-way ERP sync at its core.

Payhawk’s published entry point is the Growth Program from £149 a month, aimed at UK and EEA businesses under 20 employees, with 10 cards and 10 seats on a single entity. Above that, pricing is quote-only and modular: a platform fee plus per-user and usage-based charges across Travel, Cards & Expenses, Bill Pay and Procure-to-Pay. The reason to pay for it is integration depth. Payhawk offers two-way sync with NetSuite, SAP S/4HANA and Microsoft Dynamics 365, plus Xero, which few rivals match.

For a group running several legal entities or a full ERP, Payhawk consolidates spend into one dashboard with per-entity budgets and approvals, and syncs with the leading HRIS systems for user provisioning. Smaller teams will find it heavier and pricier than they need. Reviewers flag that KYB onboarding for multi-entity setups can take a couple of weeks, so plan the rollout. Businesses weighing up finance tooling more broadly may also want our business finance guides.

SAP Concur is the enterprise standard, unifying travel booking, expense, and invoice in one heavily integrated platform for large finance functions.

Concur does not publish pricing; the UK site routes you to a demo or a quote, which tells you who it is built for. What you get for an enterprise contract is breadth: automatic receipt capture, a policy engine that enforces rules at the point of claim, 300+ pre-built integrations, and a single suite spanning Travel, Expense and Invoice. For a multinational with complex travel policies and an existing SAP or ERP stack, that consolidation is the draw.

The recurring criticism is the interface, which reviewers describe as dated next to newer card-led tools, and the implementation effort that any enterprise rollout demands. Smaller UK businesses will find it overkill and hard to justify against Moss or Pleo. Concur has no AppWiki feed, so we list it purely on merit for readers who genuinely need enterprise scale.

Expensify is the low-cost, self-serve choice, built around fast receipt SmartScan and simple reimbursements for startups and small teams.

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, UK buyers should factor in currency conversion and card FX when budgeting rather than assuming a flat pound figure.

SmartScan receipt capture is the standout, and Collect integrates with QuickBooks Online and Xero, while Control adds NetSuite, Sage Intacct and Workday. It is a strong, cheap fit for teams that mainly need receipts and reimbursements without cards or heavy approvals. Reviewers occasionally cite app stability and a divisive interface redesign. Like Concur, Expensify has no AppWiki feed and is listed on merit.

Tide bolts lightweight expense cards onto its business account, which makes it the easy choice if you already bank with Tide.

Tide’s expense cards are a £5 per seat a month add-on that gives each cardholder 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. For a sole trader or micro-team that wants banking and simple expense control in one app, that bundling is genuinely convenient.

It is deliberately lightweight, so do not expect the AP automation or multi-entity depth of Moss or Payhawk. Transactions auto-label into accounting categories and sync to your books, which covers the basics well. If you also take card payments, it is worth understanding how business banking and merchant accounts fit alongside an expense tool.

Wallester is a card-issuing platform rather than a full expense suite, and understanding that distinction saves you from picking the wrong tool.

Wallester’s free tier is unusually generous: 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 (the site prices in euros) for larger allocations. For a business that needs to issue lots of cards fast, for ad spend, contractors or embedded programmes, the economics are excellent.

Be clear about what it is not. Wallester has no receipt OCR, no native Xero, QuickBooks or ERP accounting sync, and no post-transaction approval workflow. Spend control is pre-set card limits, not manager sign-off after the fact. If you want a finance team’s expense process, choose Moss or Pleo; if you specifically want cheap, high-volume card issuing with an API, Wallester is a strong, honest fit.

Capture Expense comes from the PSSG group behind Cintra payroll, so its strength is joining expenses to payroll and HR in one UK-focused stack.

Capture Expense is quote-only with a 14-day free trial, and it is built for mid-to-large UK organisations rather than self-serve startups. It consolidates reimbursements, bills and corporate-card transactions, with mobile receipt OCR, real-time reporting, policy enforcement and duplicate-claim detection. Two features stand out for UK finance teams: built-in VAT calculation and automated mileage, both of which reduce manual work at month-end.

Because it is part of a payroll and HR group, Capture Expense makes most sense if you already run, or want to run, Cintra payroll alongside it. Open Banking integration across 100+ banks and multi-stage approvals round out a capable platform. If payroll and expenses sitting together matters to you, it is worth a look; if you want a standalone card-led app, the others here are a cleaner fit. Teams reviewing their wider stack may also compare HR software.

How We Compared These Expense Management Providers

We compared eight UK expense management platforms, verifying every price directly against each provider’s live site in July 2026 and assessing features, integrations, and support across a consistent set of criteria.

Our assessment weighted four things: verified pricing and how transparent it is, feature depth (cards, receipt OCR, approvals, accounting sync), UK fit (VAT, mileage, HMRC compatibility), and real user sentiment from review platforms. Where a provider does not publish pricing, we say so plainly rather than guessing. Two platforms here, SAP Concur and Expensify, have no affiliate arrangement with us and are included purely because buyers expect to see them, which keeps the comparison honest.

How to Choose the Right Expense Management Software

The right choice comes down to your team size, whether you need corporate cards, and how your accounting stack is set up. Match the tool to those three factors before price.

Choose Moss if you want one platform for cards, bills and reimbursements without per-user pricing, and your books are in Xero or QuickBooks. Choose Pleo if you are a small, card-first team that wants published, predictable pricing. Choose Payhawk if you run multiple entities or need two-way ERP sync with NetSuite, SAP or Dynamics.

Choose SAP Concur if you are an enterprise with complex travel policies and an existing SAP stack. Choose Expensify if you mainly need cheap, fast receipt scanning and reimbursements. Choose Tide if you already bank with Tide and want simple expense cards bundled in. Choose Wallester only if your real need is high-volume virtual-card issuing, not a full expense process.

What Expense Management Software Actually Costs: A Worked Example

To make pricing models comparable, here is what a 25-employee UK company with 10 active cardholders would realistically pay each month across the transparent providers.

On Pleo Essential, 25 users cost £45 base plus 22 extra users at £11, roughly £287 a month. On Tide with a Pro account (£27.49, two free seats), eight paid expense-card seats at £5 bring the total to about £67 a month all in, though that buys banking rather than a full expense platform. On Expensify Collect, 25 members at $5 is around $125 a month in USD, before FX. Moss charges a flat platform fee plus transaction volume with no per-user fee, which usually wins as headcount rises but needs a quote. The lesson: per-user tools look cheap at five users and pricey at fifty, so model your real headcount first.

Expense Software and UK Compliance: VAT, Making Tax Digital and Mileage

UK businesses have specific compliance needs that global tools sometimes handle poorly: reclaiming VAT on expenses, keeping digital records under Making Tax Digital, and applying HMRC mileage rates correctly.

Under Making Tax Digital for VAT, VAT-registered businesses must keep digital records and file through compatible software, so your expense tool should export cleanly into an MTD-ready accounting system like Xero or QuickBooks rather than trapping data in spreadsheets. For mileage, HMRC’s approved rates are 45p per mile for the first 10,000 business miles and 25p thereafter for cars; tools with automated mileage, such as Capture Expense, Pleo and Payhawk, apply these without manual maths.

On VAT, look for line-level VAT capture on receipts so you can reclaim accurately. Capture Expense builds VAT calculation in directly, while card-issuing tools like Wallester leave VAT handling to your accounting software. Getting this right is the difference between a smooth quarter-end and a scramble.
