How can we enable 'Request to Pay' for our international B2B clients?

Most B2B finance teams want the benefits of Request to Pay—fewer late payments, cleaner reconciliation, and better cash flow visibility—but struggle when they try to extend it across borders, currencies, and banking systems. Enabling Request to Pay for international B2B clients requires more than a UX feature; it needs the right payment rails, compliance stack, and real-time, multi-currency infrastructure behind the scenes.

This guide walks through how to enable Request to Pay for your international B2B clients, step-by-step, and how platforms like Cybrid can help you implement it using stablecoins and programmable payments APIs.

What “Request to Pay” Means for International B2B

Request to Pay (R2P) is a digital request for payment that a payer can approve, schedule, part-pay, or reject. In a B2B context, this typically replaces or augments invoices with an interactive, real-time payment request.

For international B2B clients, Request to Pay typically aims to:

Reduce FX and wire fees on cross-border invoices
Shorten settlement times from days to minutes or seconds
Improve remittance data quality for automated reconciliation
Provide better visibility into payables and receivables
Reduce disputes and payment exceptions

To enable this at scale, you need to orchestrate:

Identity and KYC/KYB for all parties
Local account or wallet creation
Payment routing (bank rails, cards, stablecoins, or a mix)
FX and liquidity management
Real-time ledgering and reporting
Regulatory and compliance controls per corridor

Step 1: Define Your Request to Pay Use Cases

Before you design flows or pick vendors, clarify how your international B2B clients should use Request to Pay:

Common use cases:

Cross-border invoicing
Supplier in Country A sends Request to Pay to buyer in Country B in buyer’s local currency.
Recurring B2B subscriptions
Monthly or usage-based billing with R2P “pull” requests instead of direct debits, especially where mandates are complex across borders.
Marketplace payouts and fees
Platform requests payment from merchants for fees, chargebacks, or settlements.
On-demand settlements
Request to Pay used for instant top-ups or settling credit lines and trade finance.

For each use case, document:

Originating country and currency
Receiving country and currency
Typical invoice size and volume
Required settlement speed (instant, same-day, T+2)
Which side initiates the Request to Pay (supplier, platform, or automated system)

This mapping will drive which rails, partners, and flows you need.

Step 2: Choose Your Payment Rails and Currencies

International Request to Pay can be implemented over multiple rails:

1. Traditional bank rails

SWIFT / cross-border wires
- Pros: Ubiquitous; works across most banks.
- Cons: Slow (T+1–3), expensive, opaque tracking, weak remittance data.
Local bank rails (e.g., SEPA, Faster Payments, ACH equivalents)
- Pros: Lower cost, sometimes near-instant domestically.
- Cons: Limited cross-border reach; complex to integrate country-by-country.

2. Card-based Request to Pay

Card-on-file billing where R2P is effectively an authorization request.
Better for smaller, predictable amounts; less ideal for large invoices due to fees and caps.

3. Stablecoin and wallet-based Request to Pay

This is where platforms like Cybrid add the most value for B2B:

Request to Pay is issued in a digital wallet interface or via API.
Payer approves and settles using stablecoins (e.g., USD stablecoins).
Your platform or Cybrid manages:
- 24/7 settlement
- Custody of assets
- Liquidity and FX into/from local currencies
- Compliance and ledgering

Advantages for international B2B:

Near-instant, 24/7 settlement across borders
Lower fees versus traditional cross-border wires
Programmable, so you can automate partial payments, expirations, or conditional approvals
Better data fidelity: you can embed invoice IDs, line items, and meta-data directly in the transaction

In practice, many platforms adopt a hybrid approach: Request to Pay is offered over both bank rails and stablecoin/wallet rails, with smart routing underneath.

Step 3: Design the Request to Pay Customer Experience

Your international B2B clients care about outcomes: less friction, fewer errors, and reliable settlement. The UX should abstract away the underlying complexity.

Key UX elements to implement

Creating a Request to Pay

Allow your clients (or your platform) to:
- Select the payer (counterparty, customer, or merchant)
- Define amount, currency, and due date
- Attach invoice or contract reference
- Add tax, discount, or early-payment incentives
- Select preferred payment rails (bank, card, stablecoin, or “smart routing”)
Delivering the Request

Deliver R2P via:
- In-app notifications
- Email with secure link
- API/webhook if payer operates via their own system
- Optional: embedded in an invoice portal or accounting integration
Payer Actions

The payer should be able to:
- Approve and pay immediately
- Schedule payment for a specific date
- Partially pay and record the reason
- Decline and provide a structured reason code
- Request changes (amount, date, currency)
Status and visibility

Both sides should see:
- Request status: sent, viewed, approved, paid, expired
- Settlement status: pending, completed, failed, reversed
- Currency and FX rate (if applied)
- Full remittance details and reconciliation fields

Cybrid’s programmable payments stack supports this by managing wallets, accounts, and ledgering, enabling you to surface clear statuses and transaction histories in your own UI.

Step 4: Map Identity, KYC/KYB, and Compliance

International Request to Pay involves regulated money movement. You must ensure every request is tied to a known, verified entity.

Core components

KYC/KYB onboarding
- Verify businesses (KYB) and any UBOs or signers (KYC).
- Handle different jurisdiction rules (e.g., EU vs. US vs. emerging markets).
Continuous monitoring
- Sanctions screening on counterparties.
- Transaction monitoring based on amount, corridor, and behavior patterns.
Regulatory per corridor
- Some countries may treat stablecoins differently or restrict certain flows.
- Limits and thresholds may differ between domestic and cross-border users.

Cybrid provides KYC, compliance, and account/wallet creation as part of its unified stack, so you can trigger R2P flows only for verified and allowed customers, without building a global compliance engine yourself.

Step 5: Implement Accounts, Wallets, and Ledgering

Every Request to Pay must be backed by robust balance and transaction tracking, especially when you’re dealing with multiple currencies and rails.

Key infrastructure requirements

Multi-currency accounts or wallets
- Hold fiat balances in different currencies where needed.
- Hold stablecoin balances that can move 24/7 across borders.
- Assign user-level accounts or wallets for every buyer/seller.
Programmable ledger
- Record each R2P: creation, update, approval, and payment events.
- Distinguish between:
  - The Request to Pay object (a pending obligation)
  - The resulting payment transaction(s) (actual settlement)
- Support partial payments and multiple settlements for one R2P.
Liquidity management
- Handle conversions between local fiat and stablecoins.
- Route liquidity to/from bank accounts when clients cash in or out.
- Manage float and buffers to avoid failed payments.

Cybrid unifies bank accounts, wallets, stablecoins, and routing in one programmable stack, so you can:

Create user accounts and wallets via simple APIs
Track balances and ledger entries per customer and currency
Orchestrate FX and stablecoin flows under the hood

Step 6: Build the Request to Pay API Flows

To enable Request to Pay for international B2B clients, you’ll typically expose API endpoints (or internal services) that orchestrate Cybrid and your other systems.

Core flows to design

Create Request to Pay
- Input: payer ID, payee ID, amount, currency, due date, metadata.
- Actions:
  - Validate counterparties are verified (KYC/KYB) and allowed to transact.
  - Log R2P in your ledger.
  - Send notification to payer.
- Optional:
  - Pre-select preferred rails (e.g., stablecoin first, fallback to bank).
List and query R2Ps
- For both payers and payees: filter by status, dates, currencies.
- For internal ops: filter by corridor, risk flags, or amount.
Approve and pay
- Input: R2P ID, payment method (wallet, bank, stablecoin, card), optional partial amount.
- Actions:
  - Check balances and limits.
  - Initiate the payment via Cybrid APIs (wallet → wallet, wallet → bank, etc.).
  - Update R2P status and link to one or more payment transactions.
  - Trigger webhooks for both sides and for your finance/reconciliation systems.
Decline, cancel, or expire
- Handle cases where payers reject or requests time out.
- Provide structured reason codes for analytics and risk (e.g., dispute vs. cashflow).
Refunds and reversals
- Support reversing payments where legally and technically possible, linking back to the original R2P.
- Adjust ledger entries and balances accordingly.

Because Cybrid is API-first, you can integrate these flows directly into your product, while Cybrid handles account creation, wallet creation, liquidity routing, and ledgering beneath the surface.

Step 7: Handle Cross-Border FX, Fees, and Transparency

For your international B2B clients, the appeal of Request to Pay depends heavily on predictability around FX and fees.

Design decisions to make

Who bears FX risk?
- Lock rate at R2P creation or at time of payment?
- Show guaranteed amount in recipient’s currency?
Who pays fees?
- Split or pass-through per rail and currency.
- Offer “no surprise” pricing by quoting all-in fees when the R2P is viewed.
Stablecoin vs. fiat presentation
- Some clients may be comfortable settling in stablecoins; others will want local fiat.
- Offer both: show equivalent amounts and let the payer choose.

Cybrid’s liquidity and stablecoin infrastructure allows you to:

Convert seamlessly between fiat and stablecoins
Offer 24/7 settlement while managing FX and liquidity constraints
Maintain clear, programmatic fee and FX logic

Step 8: Integrate with ERP, Billing, and Reconciliation

To truly unlock value for international B2B clients, Request to Pay must plug into their existing finance systems.

Integration best practices

ERP/accounting sync
- Sync R2P creation as pending invoices.
- Sync payments as cash receipts with full remittance data.
Billing system integration
- Auto-generate R2Ps from invoices, subscriptions, usage-based charges.
- Update invoice statuses based on R2P outcomes.
Reconciliation workflows
- Use transaction IDs, invoice IDs, and metadata to auto-match.
- Surface unmatched or partial payments for exception handling.

Because Cybrid’s infrastructure provides detailed ledger entries and transaction metadata, your platform can feed structured data into clients’ back-office systems, dramatically reducing manual reconciliation work.

Step 9: Roll Out Request to Pay Across Corridors in Phases

Enabling Request to Pay globally from day one is risky. A phased rollout is more practical.

Suggested rollout strategy

Pilot with a single corridor
- Start with a high-volume pair (e.g., US ↔ EU).
- Use stablecoin-based R2P + local bank payouts as a first pattern.
Add additional corridors and currencies
- Prioritize based on customer demand and regulatory readiness.
- Reuse the same Cybrid-based architecture, just enabling new rails/currencies.
Optimize based on data
- Track acceptance rates, time-to-pay, FX spreads, and failure reasons.
- Tune default rails, messaging, and fee structures accordingly.
Scale to broader customer segments
- Move from a small beta to your wider B2B base.
- Introduce R2P into new products (e.g., marketplace payouts, partner billing).

With Cybrid’s programmable stack, each new corridor is largely a configuration and integration extension—not a full rebuild of your payments infrastructure.
