What Is Moss?
Moss is a UK and EU expense management platform that combines corporate cards, accounts payable automation and employee reimbursements in a single dashboard. It’s built for finance teams who want to control company spend without juggling separate tools for cards, bill payments and receipt chasing.
The platform is built around three modules: Corporate Cards, Accounts Payable and Reimbursements, and you can adopt one or all three depending on what your finance team needs. Every card transaction and invoice is designed to sync automatically with your accounting software, cutting the manual data entry that eats into a bookkeeper’s week. Approval steps and spend budgets are configurable per team, department or cost centre, so finance leaders keep control without approving every purchase personally.
Moss Key Features
Moss’s standout features are unlimited physical and virtual cards, AI-powered receipt reading, and deep accounting sync across 50+ platforms. Together they let a finance team run cards, bills and reimbursements from one place instead of stitching together three separate subscriptions and chasing paper receipts every month end.
Corporate Cards and AI Receipt Capture
Moss issues unlimited physical and virtual cards to employees, each with its own spend limit and category rules set by finance. When a card is used, Moss’s AI reads the receipt photo, extracts the amount, VAT and merchant, and auto-categorises the transaction, so employees rarely need to type anything manually. Multi-currency support covers more than 70 currencies, which matters for any UK business paying suppliers or contractors abroad.
Accounts Payable and Reimbursements
The Accounts Payable module automates invoice capture, approval routing and supplier payments, while the free plan alone covers up to 20 invoices a month. Employee reimbursements follow the same approval logic as card spend, so out-of-pocket expenses and card transactions sit in one review queue instead of two separate processes finance has to reconcile by hand.
Approval Controls and Multi-Currency
Approval workflows are customisable by team, spend category or amount threshold, and budgets can be set at company, department or project level. Combined with support for 70+ currencies, this makes Moss a workable option for UK SMEs with international contractors, remote hires or suppliers billing outside sterling, without needing a separate FX tool.
Moss Pricing UK 2026
Moss’s free plan covers up to 3 users with unlimited cards, which is unusually generous for a category where most competitors charge per seat from day one. Paid plans move to a custom quote once you need more users or higher invoice volume.
The free tier includes up to 20 invoices a month and customisable approval steps, enough for a small team to run genuine spend before paying anything. Once you outgrow the free limits, Moss moves to a flat platform fee per module (Corporate Cards, Reimbursements, Accounts Payable) plus a variable fee tied to your monthly transaction volume.
Crucially, there’s no per-user charge, unlike many card-led competitors that add a fee per seat once you exceed a handful of included users. That structure matters most once a team grows past 10-15 staff, when per-seat pricing elsewhere starts compounding fast. For a smaller team on a tighter budget, our best expense management software for small business guide compares budget-friendly options side by side.
Moss Integrations
Moss connects to 50+ accounting and ERP platforms, including Xero, QuickBooks, NetSuite, SAP and Dynamics 365. For most UK SMEs already running Xero or QuickBooks, that means transactions and invoices sync automatically without a manual export-import routine.
Two-way sync means categorised transactions, approved invoices and reimbursements post straight to your ledger, cutting the reconciliation work a bookkeeper would otherwise do by hand. Larger UK finance teams running NetSuite, SAP or Dynamics 365 for group reporting get the same depth of integration Moss offers smaller Xero and QuickBooks users, which is unusual at this price point.
If you also need dedicated payroll software to run PAYE, pair Moss with a specialist like our best payroll software guide rather than expecting an expense tool to double up. Expense management and payroll solve different problems, and trying to force one platform to do both usually means compromising on both fronts.
Who Is Moss Best For?
Moss suits UK and EU SMEs of roughly 10 to 100 employees that already run Xero or QuickBooks and want cards, bill payments and reimbursements without paying a fee for every new starter. It’s a weaker fit for solo traders or very large enterprises with complex procurement needs.
Moss is the strongest fit for finance teams that want one platform instead of three: a business issuing company cards to 10-50 staff, a team drowning in paper receipts and manual expense reports, or a UK SME on Xero or QuickBooks that wants invoices, cards and reimbursements to sync automatically.
It also works well for teams with international suppliers or contractors, thanks to support for 70+ currencies, and for finance leads who want configurable approval rules rather than a one-size-fits-all workflow. If employee cards specifically are your priority, our best business expense cards guide narrows the shortlist to card-first options.
Moss is less suited to sole traders who don’t need multi-user approval flows, or to enterprises already committed to a travel-and-expense suite. If your priority is the cheapest possible card issuing with no accounting sync, a card-only tool will undercut Moss on price but leave your bookkeeper doing more manual work.
Best Moss Alternatives
The two strongest alternatives to Moss are Pleo, which publishes its pricing upfront, and Payhawk, built for multi-entity businesses on NetSuite or SAP. Both are solid UK options if Moss’s quote-only paid pricing or module set doesn’t fit your team.
Pleo starts from £9.50 a month for 3 users on its Starter plan, rising to £45-£219 a month plus £11-£18 per extra user as you move up the tiers, so you always know the cost before you commit. It doesn’t offer a genuinely free plan, but the published pricing suits finance teams that want budget certainty over Moss’s quote-only model.
Payhawk’s Growth Program starts from £149 a month for UK and EEA businesses under 20 employees, covering 10 cards and 10 seats. Above that, Payhawk moves to a quote-only platform fee plus per-user and usage charges, with two-way sync to NetSuite, SAP S/4HANA and Dynamics 365 that goes deeper than Moss for multi-entity groups.
It’s the better choice once you need multi-entity consolidation Moss doesn’t offer, though you lose Moss’s free tier and simpler quote-only structure for cards and reimbursements alone. For the full field of eight verified UK providers, see our best expense management software comparison.
Moss Pros and Cons
Moss’s biggest strength is combining cards, accounts payable and reimbursements in one platform without charging a per-user fee. Its main limitation is that paid pricing beyond the free tier isn’t published, so you’ll need a short sales conversation before you know the real monthly cost for your team.
Our Verdict
Moss earns an 8.6/10 in our review for combining corporate cards, accounts payable and employee reimbursements without charging by the seat. For most UK SMEs already running Xero or QuickBooks, it’s the strongest all-round pick in this comparison, ahead of card-led rivals like Pleo.
Moss is the best all-round expense management platform for most UK SMEs, combining cards, accounts payable and reimbursements without a per-user fee. Paid pricing is quote-only, but the free tier and integration depth make it our Editor's Pick.
