Why teams connect Adyen and Rillet

Keep the customer, invoice, and payment records that Adyen and Rillet share consistent in real time, whether the two systems split your finance stack or one is replacing the other.

Two finance systems in one company usually means one of two setups. Either the systems divide the work, with one issuing invoices or serving a business unit while the other holds the books, or one is on its way out and both must stay accurate during the transition. In both cases, the customer, invoice, and payment records the two systems share start to drift the moment updates are keyed twice or moved by hand.

Stacksync syncs Settlement Detail Reports, Payments, Modifications (Captures, Refunds, Cancels), Payment Links in Adyen with Bill, Journal Entry, Invoice Payment, Charge in Rillet bi-directionally and in real time. A record created or corrected in either system appears in the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most at close. When both systems agree on who was billed, what was paid, and what is outstanding, reconciliation stops being a hunt for which copy of the truth is current.

Common use cases

  • 01 Trigger a capture, refund, or cancel on an Adyen payment when an order's state changes in a CRM, OMS, or ERP, and write the returned pspReference and status back onto the record.
  • 02 Create Adyen Payment Links from an invoicing or billing system and sync each link's paid or expired status back so accounts receivable sees payment without opening the Customer Area.
  • 03 Sync AR and collection status back to customer success tools ahead of renewals.
  • 04 Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.

Common sync patterns

Payment status everywhere

A payment applied in one system updates the matching invoice in the other, so no one chases a balance that was already settled.

Entity or business-unit roll-up

Where each system serves a different entity or unit, sync the shared records so group-level reporting starts from consistent data.

Where Adyen issues invoices and Rillet holds the books

Invoices and payments recorded on the billing side land in the system of record automatically, so revenue is captured once and correctly.

What you can sync between Adyen and Rillet

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Adyen objects Rillet objects How this pairing syncs
Settlement Detail Reports Downloadable reports of settled transactions, fees, and payouts per merchant account; read-only, delivered when a report webhook fires, and loaded for finance reconciliation. Account Synced with incremental and full sync per the Stacksync docs. Settlement Detail Reports is specific to Adyen and Account to Rillet — each maps to any object or custom field on the other side.
Payments Checkout API payment requests and results (/payments); created to authorize a card, wallet, or local payment, and retrieved by pspReference. Final state arrives asynchronously via the AUTHORISATION webhook. Customer Synced with incremental and full sync per the Stacksync docs. Payments is specific to Adyen and Customer to Rillet — each maps to any object or custom field on the other side.
Modifications (Captures, Refunds, Cancels) Actions on an authorized payment via /payments/{pspReference}/captures, /refunds, and /cancels; written to settle, return, or void funds, with results confirmed by CAPTURE and REFUND webhooks. Vendor Synced with incremental and full sync per the Stacksync docs. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Vendor to Rillet — each maps to any object or custom field on the other side.
Payment Links Hosted payment link objects created through /paymentLinks; created, retrieved, and expired, with paid or expired status reported back through webhooks for accounts-receivable sync. Invoice Synced with incremental and full sync per the Stacksync docs. Payment Links is specific to Adyen and Invoice to Rillet — each maps to any object or custom field on the other side.
Merchant Accounts Company and merchant account entities in the Management API; read and updated to keep account configuration, payment-method settings, and capabilities aligned with internal systems. Credit Memo Synced with incremental and full sync per the Stacksync docs. Merchant Accounts is specific to Adyen and Credit Memo to Rillet — each maps to any object or custom field on the other side.
Stores Physical and online store entities under a merchant account (Management API); full CRUD, so new locations and their payment-method configuration can be provisioned from an internal admin source. Bill Synced with incremental and full sync per the Stacksync docs. Stores is specific to Adyen and Bill to Rillet — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Rillet

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Adyen Rillet Sub-second propagation

DetectionAdyen notifies Stacksync of record changes through webhook events. Standard webhooks for payment events (AUTHORISATION, CAPTURE, REFUND, CHARGEBACK, and more) plus Management, Balance Platform, and report webhooks.

DeliveryEach detected change is written to Rillet through its API, with automatic retries and rate-limit backoff.

Rillet Adyen Sub-second propagation

DetectionRillet pushes changes as they happen — webhook events backed by change data capture. Near real-time updates via change tracking.

DeliveryEach detected change is written to Adyen through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Adyen: Adyen does not publish fixed numeric rate limits; excessive requests return HTTP 429, and the Management API reports 'too many requests' in the error detail. Adyen recommends exponential backoff, and no rate-limit response headers are documented.
  • Rillet: Subject to the platform's API rate limits.
