Moss is spend software for companies in the UK and Europe. You issue Mastercard corporate cards, virtual or physical, collect employee reimbursements (including mileage and per diems), and run supplier invoices through approval. Receipts are photographed in the app, emailed, or pulled from Gmail or Outlook. Moss codes the spend, including VAT rates, then syncs or exports it to the accounting system you already use. Project and cost-centre tracking is listed on the AI accounting add-on. Supplier payments and reimbursements go out as Pay with Moss from a Moss wallet, or as a SEPA file for reimbursements.

Ramp and Brex are US card programs with US underwriting and a sync aimed at US books. Bill.com and Melio pay US vendors by ACH. Moss is the European shape of that stack: a card, a wallet, and an invoice queue, with DATEV for German firms and cost centres in the coding. It does not replace the ledger. Moss Credit, the repay-later option, is offered in Germany, the Netherlands, and the UK. The other documented way to fund spend is a debit wallet. Rydoo is the closer comparison if you only need expense reports and you do not want a card program.

Finance teams keep it because cards, invoices, and out-of-pocket claims share one approval trail and one coding setup, and the platform fee does not grow with headcount. Employees can put a card in Apple Pay or Google Wallet and spend inside the limit you set. Month-end is still the sync or export into Xero, DATEV, Business Central, NetSuite, or whichever ledger you connected.

Virtual cards are unlimited and can be created for a merchant, project, or single use. Physical cards are available. Controls include per-card and per-transaction limits, merchant category, and time restrictions. Cards can be added to Apple Pay or Google Wallet. Moss says there is no annual card fee and no per-user card fee.

Issue a Mastercard with a limit

Moss Debit draws from the Moss wallet. Moss Credit is repayable daily, weekly, or within 30 days, with 0% interest if you repay on time, and it requires a credit check. The legal center limits Moss Credit to Germany, the Netherlands, and the UK. Eligibility applies.

Fund the card with credit or a debit wallet

Spenders submit a photo in the app or by email. Receipt Finder can pull receipts from Gmail or Outlook. The AP and card modules both list AI extraction. Reimbursements support mileage and per diems, then pay from the Moss balance or a SEPA file, with a second approver on payment.

Collect the receipt without a chase email

Invoices go through multi-step approval, can auto-match to a purchase order, and can be scheduled in one payment list. Pay with Moss sends the payment from the Moss wallet. In the EEA that wallet is provided by Moss GmbH, with Airwallex named for the onward payment. In the UK, Airwallex (UK) provides the wallet and Pay with Moss.

Approve and pay supplier invoices

The integrations page lists live connections including Xero, DATEV, NetSuite, Microsoft Business Central, and SAP Business One, plus CSV paths such as Sage 50 and Sage 200. The card FAQ also names QuickBooks and Exact. Sage Intacct is marked coming soon. ERP dimensions are an add-on, not the free start.

Push coded spend to the ledger you already keep

Moss issues European corporate cards and runs invoices and reimbursements into Xero, DATEV, or an ERP. Paid prices are not published.

Perk (the TravelPerk rebrand) is a travel and spend platform, not a ledger. Employees book flights, hotels, trains, and cars inside the app. Policy applies at booking. Receipts get photographed on the phone, matched to a card charge or claim, and checked against the same rules. Finance exports or syncs coded expenses into the accounting system instead of rebuilding the trip from inboxes.

It does not replace QuickBooks Online or Xero. The trip record lives here, then a spend export or a Xero connector (DATEV and Xero on Spend Premium) hands coded lines to the books. That is the opposite of Ramp (a card program with travel on the same login) or Expensify (a phone camera for out-of-pocket receipts). Navan is the closer US booking-plus-expense stack if you want a product you can start without a waitlist. Confirm QuickBooks Online on Perk's US connector list before you buy; the public Spend table we saw did not list it.

People who stick with Perk are usually teams that already book travel every month and want the same rules on the fare and the dinner. They care most about travelers staying in one app, and finance getting a coded trip instead of three inboxes.

Employees search flights, hotels, trains, and cars in the app. Starter includes one travel policy. Premium includes 10. Pro is unlimited. Out-of-policy options can be blocked or routed before the money leaves.

Book the trip in policy

Photograph a receipt on iPhone or Android. Perk reads the line items, matches the card charge, and applies expense rules (10 on Spend Premium, unlimited on Pro) before the report sits in a queue.

AI receipt capture and policy check

Issue unlimited physical, virtual, and lodge Platinum Visa debit cards at no extra card fee. Set spend limits. Premium lists 0.5% cashback; Pro lists 1%. External card feeds are one per entity.

Perk Visa debit cards

Booked travel can spawn the expense, assign a per diem, and attach the itinerary so meals and ground transport sit on the same trip instead of three personal-card claims.

Trip and expense as one record

Spend Premium includes a spend export file plus DATEV and Xero connectors. Pro adds the rest of their ERP connectors and an OpenAPI. Confirm QuickBooks Online on the North America list before you buy.

Export or sync to the books

The Perk app (iOS and Android) holds the itinerary, live flight updates, receipt camera, card requests, and travel approvals so the traveler does not need a laptop at the hotel.

Mobile booking and approvals

Perk combines travel booking, expenses, AI policy checks, and Visa debit cards. Published US prices, the catch, and who should skip it.
