Payments and banking is what we do.
Most payment problems are not technical. They are underwriting, jurisdiction and relationship problems. KLAUDE handles both layers — the infrastructure and the expertise to use it.
Acquiring
Placement with acquiring partners that accept your model, markets and volume.
Underwriting
Your business reviewed before any application, so it reaches the right desk complete.
Routing
Each transaction directed to the path most likely to be approved at the lowest cost.
International processing
Local acquiring and local payment methods in the markets your customers are in.
Settlement
Multi-currency settlement, clear timing, and reserves negotiated against real risk.
Fraud
Screening and 3-D Secure configured for your customers, not a generic template.
Chargebacks
Alerts, prevention and representment to keep ratios inside scheme thresholds.
Optimisation
Ongoing analysis of approval rates and cost, with changes that move the number.
Talk to us about
Four things, done properly. Most clients start with one and end up using three.
Payment processing
Cards and alternative payment methods, globally — deposits and payouts, placed with acquirers that accept your model and markets.
Processing solutionsBanking
Introductions to a global banking network for B2B account opening, transfers and foreign exchange — the accounts your acquirers need to settle into.
Banking & FXPayment technology
Orchestration, routing, tokenisation and integration advice. Your card data stays portable between providers, so no acquirer owns your business.
OrchestrationCompliance & risk
Policies, KYC/AML procedures and scheme-rule compliance built for underwriters — and maintained as the rules change.
Compliance advisoryHigh-risk merchant accounts for every complex industry.
Lawful businesses in categories that mainstream providers decline or misunderstand. Eligibility depends on jurisdiction, licensing, compliance and acquirer requirements.
Several acquirers. One payment layer.
The KLAUDE payment layer sits between your checkout and your providers. Transactions are routed by rule and by performance; soft declines cascade to an alternative acquirer; outages fail over automatically. You see one integration and one set of reports.
- Route by card type, issuing country, amount and acquirer performance
- Cascade soft declines where card-scheme rules permit
- Add or replace acquirers without changing your integration
- Unified reporting across every provider and method
Wherever you want to go, we know the market, the people — and they trust us.
Acquiring is a relationship business. Underwriters say yes to applications presented by people they have worked with for years. That is what you are hiring.How it works
Four steps from first conversation to live processing.
- 1
Tell us about your business
A few minutes in our application form: model, markets, volume, what you need.
- 2
Payment review
We assess your profile, identify which acquirers and methods fit, and tell you honestly what is realistic.
- 3
Match infrastructure
Applications go to the right partners, complete. We negotiate terms, reserves and limits.
- 4
Start processing
Integrate once. Go live. We keep optimising approval rates, cost and resilience.
Final acceptance depends on business model, jurisdiction, KYC/KYB, licensing, acquirer underwriting and card-network requirements. KLAUDE does not guarantee approval.

Questions merchants ask before they apply
What types of businesses does KLAUDE work with?
Businesses whose payment requirements are more complex than a standard retailer's: subscription models, continuity billing, digital services, travel, marketplaces, gaming, dating, nutraceuticals, CBD, telehealth, credit repair, MLM, vape, peptides, crypto, forex, content platforms, ticketing, high-volume merchants and cross-border sellers. Each category has its own requirements around licensing, jurisdiction and acquirer policy, which we assess in the review.
Does KLAUDE support high-risk merchants?
Yes. Many of the businesses we work with would be labelled "high risk" by mainstream processors. We prefer to think in terms of complex requirements rather than risk labels, but the practical answer is that we arrange acquiring for categories most providers decline — provided the business is lawful, licensed where required and willing to meet acquirer standards.
How long does merchant onboarding take?
Our initial review typically takes a few business days. Acquirer underwriting then ranges from under a week for straightforward profiles to several weeks for complex or licensed categories. The largest factor is how complete your documentation is — we give you a checklist up front so nothing is missing.
Can KLAUDE provide multiple merchant accounts?
Where it makes sense, yes. Multiple MIDs across different acquirers give you redundancy and allow volume to be spread. Note that card-scheme rules prohibit using multiple accounts to disguise volume or evade monitoring programmes; we only structure multi-acquirer setups for legitimate resilience and optimisation purposes.
Can KLAUDE help with international payment processing?
Yes. We arrange local acquiring and local payment methods in Europe, the UK, North America, LATAM and APAC where your business profile qualifies. Some markets require a local entity or licence; we explain those requirements before you commit.
Which currencies are supported?
Presentment in 100+ currencies and settlement in major currencies including EUR, GBP and USD are available depending on the acquiring partner. Exact currency support is confirmed during placement.
Does KLAUDE support recurring billing?
Yes. We work with acquirers that accept subscription volume and provide tokenisation, account updater, retry logic and descriptor best practice to keep renewals high and disputes low.
What information is required for underwriting?
Typically: company registration documents, ownership and director identification, a working website with terms, privacy and refund policies, 3–6 months of processing statements if you have processed before, bank statements, and any licences relevant to your category. A full checklist is provided after your initial review.
What causes a merchant account to be declined?
The most common reasons are incomplete documentation, an unclear or non-compliant website, a chargeback ratio above scheme thresholds, presence on the MATCH list, unlicensed activity in a regulated category, or simply applying to an acquirer that does not accept the business type. Most of these are fixable, and identifying them in advance is the point of our review.
Can I use KLAUDE as a backup acquiring solution?
Yes. Many merchants come to us for a second acquirer to sit alongside an existing one, so that a provider change, outage or limit does not interrupt processing. Orchestration lets you route between them.
Does KLAUDE provide payment orchestration?
Yes. A single integration connects to multiple acquirers and payment methods with routing, failover and unified reporting. It is optional — some merchants use KLAUDE for acquiring placement only.
Does KLAUDE work with startups?
Yes, with realistic expectations. Businesses without processing history are underwritten more conservatively, which usually means lower initial limits and possibly a reserve. We will tell you honestly whether an application is likely to succeed before you spend time on it.
