Why Moss

Every penny. Tracked, approved, and reconciled.

Corporate cards with built-in controls

Issue physical and virtual Mastercard cards to your team instantly. Set per-card spend limits, merchant-category restrictions, and get real-time alerts — so you're always in control before money leaves the business.

Automated accounts payable

Moss ingests invoices from email, upload, or scan — extracting data automatically, running duplicate and VAT checks, routing through custom approval workflows, and executing bulk or multi-currency payment runs.

Painless employee reimbursements

Staff submit out-of-pocket expenses by snapping a photo of their receipt on mobile. Moss auto-categorises the spend, calculates mileage, routes it for approval, and pays out instantly — no spreadsheets required.

AI-powered coding & reconciliation

Moss's accounting AI automatically assigns nominal codes, VAT rates, cost centres, and tracking categories across every transaction type. Month-end close becomes a quick review, not a rebuild from scratch.

We implement and manage Moss for UK businesses — handling everything from setup and Xero integration to card provisioning, team training, and ongoing support. Get in touch and we'll take it from there.

Get Started with Moss

Built for Xero.
Works the way you do.

Seamless. Automatic. Accurate.

Moss is a Xero-approved app. It connects via a secure OAuth API and immediately mirrors your chart of accounts, suppliers, tax rates, and tracking categories — no manual mapping, no CSV headaches, no configuration errors. Any change you make in Xero reflects in Moss automatically, so your coding stays consistent without you lifting a finger.

When a transaction is approved in Moss — whether that's a card payment, a supplier invoice, or an employee reimbursement — it syncs to Xero complete with receipts and a full audit trail attached. Transactions are auto-reconciled against your Xero bank feed, so there's no bank matching screen to work through at month-end.

Managing multiple entities? One Moss account can connect to several Xero organisations, giving you a single view of spend across the whole business. And because the Xero integration is included in every standard Moss plan, there's no extra cost.

Talk to us about Moss + Xero
1
Connect in minutes

Authenticate via Xero's approved OAuth process. Moss instantly imports your chart of accounts, tax codes, supplier records, and tracking categories — zero manual setup.

2
Always in sync

Changes to your Xero chart of accounts, tax rates, or supplier list flow into Moss automatically. Create or update suppliers in Moss and they sync back to Xero too.

3
Review, approve, and export

Set custom approval workflows by spend type, entity, project, or cost centre. Approved card payments, invoices, and reimbursements — with receipts — sync on demand.

4
Auto-reconciled in Xero

Transactions post directly to Xero and reconcile against the bank feed automatically. Prepayment schedules and journal entries are created for you. Month-end becomes a quick check, not a rebuild.

Xero-approved app

Moss is an officially approved Xero integration. Your data moves over encrypted, OAuth-secured channels — only the specific data required is accessed, and all activity is logged for compliance.

No bank matching required

Moss transactions auto-reconcile against your Xero bank feed — no manual matching needed. Receipts and audit trails are attached to every entry, keeping your records clean and audit-ready.

Multi-entity support

Manage spend across multiple Xero organisations from one Moss account. Configure approval rules, cost centres, and tracking categories independently for each entity.

Included in every plan

The Xero integration isn't a paid add-on — it's included in all standard Moss plans at no extra cost. Cards, invoices, and reimbursements all sync through the same connection.

FAQs

What is Moss?

Moss is a unified finance platform that brings together corporate cards, invoice processing, and employee reimbursements in one place. It automates expense capture, approval workflows, and reconciliation — so your team spends less time on admin and your books are always up to date.

How does Moss integrate with Xero?

Moss connects to Xero via a secure OAuth API. It pulls your chart of accounts, suppliers, tax codes, and tracking categories directly from Xero, then syncs approved transactions back automatically — including receipts and audit trails. There is no manual bank matching or data entry required.

What types of spending does Moss cover?

Moss covers all employee and business spending: corporate card transactions, supplier invoices, and out-of-pocket employee expense claims. All three are managed, approved, and reconciled in a single platform.

Can we set spending limits and approval rules?

Yes — Moss gives you granular controls before money is spent. You can set per-card limits, require purchase orders above certain thresholds, create custom approval workflows by team or spend category, and get real-time alerts on out-of-policy purchases.

How long does it take to get started?

Most businesses are up and running within a day. Connecting Moss to Xero takes just a few clicks, and we handle the full setup — card issuance, approval workflows, accounting mappings, and team onboarding — so you can go live quickly and confidently.

What support do you provide after setup?

We manage the complete implementation — Xero connection, chart of accounts mapping, card provisioning, and team training. After go-live we remain on hand for workflow changes, new user onboarding, and any technical support you need.

Does Moss support purchase orders and procurement?

Yes — with the Procurement add-on, Moss extends into a full procure-to-pay workflow. Employees raise purchase requests in a few clicks; approvers match them to budgets and convert approved requests into supplier-ready POs. When invoices arrive, Moss automatically matches them to pre-approved spend — so if the details align, the invoice is approved without any manual review. Every step is logged for compliance.

Can Moss connect directly to our ERP?

Yes. The ERP add-on provides purpose-built, dedicated connectors for Oracle NetSuite, Microsoft Dynamics 365 Business Central, and SAP Business One. Each connector syncs complete, categorised, audit-ready spend data — including all relevant dimensions — directly into your ERP. For other systems, the Moss API lets you build custom integrations or connect BI tools and data warehouses. Dedicated onboarding and ongoing support are included.

What card types does Moss issue?

Moss issues physical and unlimited virtual Mastercard cards, accepted worldwide. Cards can be configured for specific purposes — single-use purchases, recurring software subscriptions, project spend, or team use. Credit-BIN cards are available for scenarios that require a credit card, such as hotel bookings and car rentals. All cards support Apple Pay and Google Wallet, and can be frozen or terminated instantly from the Moss dashboard.

How does employee mileage reimbursement work?

Employees submit mileage claims via the Moss mobile app. Moss automatically calculates the reimbursement amount using either company-configured rates or HMRC advisory rates, and generates a full calculation trace for audit purposes. Finance can configure VAT enforcement and mandatory audit fields, and once approved, payouts are made instantly directly from the Moss platform — no separate payroll run required for straightforward mileage claims.
