How to offer instant account-to-account top-ups for SMEs with open banking payments

Yapily enables platforms to offer near-instant account-to-account (A2A) top-ups for SMEs using secure open-banking payments. By connecting directly to bank APIs, Yapily enables businesses to transfer funds between accounts within seconds or minutes, no cards, no manual bank transfers, and minimal settlement delay.

Why SMEs need instant top-ups

Maintaining liquidity is essential for SMEs. Delays in topping up wallets, prepaid cards, or funding accounts can disrupt operations, lead to failed payments, or cause cash-flow issues.

Open banking provides a faster, regulated, direct bank-to-bank transfer route. With Yapily Payments, your platform can:

  • Deliver near-instant settlement between business bank accounts

  • Reduce transaction costs compared to traditional card payments or manual transfers

  • Minimise payment failures by leveraging strong customer authentication (SCA) via open banking

  • Simplify the experience: no card entry, no manual bank details, no batch-settlement delays

Platforms that serve SMEs, such as spend-management tools, FX platforms, and fintech lenders, can offer a fast, streamlined top-up flow that meets modern user expectations.

How instant top-ups work with Yapily

  1. User selects “Top-Up”: On your platform, the SME initiates a wallet or account top-up.

  2. Bank selection and authorisation: Yapily’s hosted or embedded flow guides the user to pick their bank and authenticate via banking app or portal.

  3. Payment initiation via PIS: Using Yapily’s Payment Initiation Service (PIS) API, the payment request is sent to the bank and routed through a fast payment rail (e.g., UK Faster Payments, SEPA Instant) where supported.

  4. Real-time confirmation: Yapily delivers instant payment-status updates via API callbacks or webhooks.

  5. Funds available swiftly: The user’s account is credited as soon as settlement occurs on the rail: no card-network delays or multiple-day batches.

The entire process is secure, PSD2-compliant, and can be fully embedded or white-labelled to match your brand.
