Two Approaches to Payment Requests
Prommt and Shuttle both help businesses collect payments remotely — through links, messages, and digital channels rather than traditional card-present terminals.
But they serve different audiences and solve different problems.
Prommt is a payment request platform for enterprise merchants. It sends branded payment links via SMS, email, and chat — with a strong focus on Pay by Bank (open banking) for high-value transactions. It sells directly to merchants in verticals like automotive, hospitality, and luxury retail.
Shuttle is a payment layer for platforms and merchants. It supports payment links, voice checkout, open banking, digital wallets, and 40+ PSPs — across embedded, white-label, and direct merchant channels.

Where Prommt Wins
Chase paths and payment retry logic
Prommt's automated chase sequences are genuinely well-built. When a payment request goes unpaid, Prommt can send follow-up reminders that offer alternative payment methods — if a card payment fails, the next reminder can default to Pay by Bank. This nudges completion rates up in a way that most payment link tools don't attempt.
Open banking depth in Europe
Prommt has invested heavily in Pay by Bank through Token.io, covering 14 European markets. For merchants processing high-value transactions (car sales, luxury goods, property deposits) where card fees become painful, Prommt's open banking coverage across Europe is broader than most competitors. They claim 60%+ of their clients now use Pay by Bank — which suggests real adoption, not just a feature checkbox.
Vertical-specific integrations
Prommt has built integrations with industry systems — Oracle OPERA for hospitality, dealer management systems for automotive. If you're a hotel or car dealership already running OPERA or a specific DMS, Prommt's pre-built connectors reduce implementation time. These are narrow but deep integrations that horizontal payment tools typically don't have.
High-value transaction optimisation
Prommt is purpose-built for high-value remote payments — car deposits, hotel stays, luxury purchases. The payment experience is designed for transactions where the customer needs reassurance and the merchant needs completion certainty. Smart defaults (Pay by Bank for transactions over a threshold, card for smaller amounts) are configured at the merchant level.
Where Shuttle Wins
Voice payments — capture during the call, not after it
This is the fundamental channel gap.
Prommt's approach to phone payments: the agent sends a payment link during the call, the customer opens it on their phone, completes payment, and confirms back to the agent. It works, but it breaks the conversation flow, adds friction, and depends on the customer having their phone and email accessible.
Shuttle's approach: the customer enters card details via keypad (DTMF) during the call. The agent stays on the line. Card tones are masked — the agent never hears them. Payment completes in seconds without leaving the conversation.
For contact centres, debt collection, insurance renewals, hotel reservations — anywhere payments happen during phone calls — voice checkout closes the payment in-call rather than hoping the customer follows a link afterwards.
40+ PSPs vs gateway-dependent
Prommt sits on top of the merchant's existing payment gateway. It doesn't process transactions — it creates a checkout page that routes to whatever gateway the merchant already has.
This works for single-merchant deployments. But it creates problems at scale:
Platforms serving multiple merchants can't configure different PSPs per merchant through Prommt
BPOs handling payments for multiple clients need multi-PSP routing — Prommt doesn't support this
**Enterprise merchants with PSP mandates** are fine, but platforms that want to offer embedded payments across a merchant base need a multi-PSP architecture
Shuttle connects to 40+ PSPs through a single integration. One API, any gateway, any merchant.
Platform and multi-merchant architecture
Prommt is designed for individual merchants. Each merchant gets a Prommt account and dashboard.
Shuttle is designed for platforms that serve hundreds or thousands of merchants. White-label onboarding, per-merchant PSP configuration, branded merchant portals, and revenue share across all transactions.
If you're a software platform, marketplace, BPO, or SaaS company embedding payments for your customers — Shuttle's multi-tenant architecture is built for this. Prommt isn't.
Pricing — significantly lower entry point
Prommt starts at €299/month with no self-service onboarding. For a car dealership processing high-value transactions, that's reasonable. For a small merchant, a BPO adding payment collection, or a platform evaluating options — it's a barrier.
Shuttle's payment links start at $49/user/month. Voice checkout is $0.20 per transaction via the Twilio Marketplace. No minimum volume commitments. Self-serve onboarding available.
Broader payment method coverage
Prommt covers cards and open banking. Shuttle covers:
Cards (40+ PSPs)
Open banking / Pay by Bank (UK)
ACH Direct Debit (US)
BACS Direct Debit (UK)
Apple Pay, Google Pay, PayPal
Klarna, Affirm (BNPL via supported PSPs)
Local payment methods via Stripe, Adyen, Mollie (iDEAL, Bancontact, Pix, etc.)
For merchants selling internationally or serving customers who prefer wallets and BNPL, Shuttle covers more payment methods out of the box.
When to Choose Prommt
You're a single merchant in automotive, hospitality, or luxury retail
High-value transactions where Pay by Bank saves significant card fees
You need Oracle OPERA or automotive DMS integration
Chase paths and automated payment retry are critical to your workflow
You need Pay by Bank across multiple European markets (14 countries)
You don't need voice payment capture, AI agents, or multi-merchant architecture
When to Choose Shuttle
You're a platform, BPO, or SaaS company embedding payments for multiple merchants
You need voice payments — capturing card details during calls, not sending links after them
You serve merchants with different PSP requirements
You want payment links AND voice checkout AND embedded payments from one provider
Pricing matters — $49/month vs €299/month
You need white-label everything: checkout, portal, onboarding
You want Apple Pay, Google Pay, BNPL, and local payment methods alongside cards and bank transfers
When to Use Both
Shuttle is PSP-agnostic — if a merchant's transactions route through a gateway that Prommt connects to, both can coexist. But in practice, Shuttle's payment links replace Prommt's core functionality at a lower price point with broader payment method support. The question is whether Prommt's chase paths and European open banking coverage are worth the premium for your specific use case.
FAQ
Is Shuttle a direct competitor to Prommt?

Can Shuttle replace Prommt for car dealerships?
Yes. Shuttle's payment links for car dealerships cover the same use case — sending branded payment requests for deposits, balances, and F&I products. Plus voice checkout for customers who call to pay, and Apple Pay / Google Pay for faster completion. See the automotive guide for the full breakdown.
What about Prommt's chase paths?
Prommt's automated follow-up sequences are a strong feature. Shuttle supports configurable reminders and link expiry. For businesses where chase automation with payment method fallback is critical, evaluate both products on this specific capability.
