Why teams connect Amazon S3 and SAP Business One

Move the documents and data that SAP Business One produces into Amazon S3 as files, and let files stored in Amazon S3 update the records they belong to in SAP Business One, continuously and without exports or manual filing.

SAP Business One runs the business on structured records: Activities, Business Partners, Items, Sales Orders. Amazon S3 holds files and the metadata that describes them: Prefixes (folders), Multipart uploads, Buckets, Objects. The two do not share a customer table or an order ledger. What they share is documents. Nearly every record SAP Business One touches produces a file that belongs in storage, whether an invoice, a purchase order, a statement, or a shipping doc, and many files that land in Amazon S3, from signed contracts to vendor bills to receipts, describe a transaction SAP Business One needs to record. Left unconnected, that link is maintained by hand: someone exports a PDF and drags it into a folder, or downloads a file and keys its details into a record.

Stacksync keeps Activities, Business Partners, Items, Sales Orders in SAP Business One and Prefixes (folders), Multipart uploads, Buckets, Objects in Amazon S3 in sync, bi-directionally and in real time. A document and its details, the customer, the type, the date, an amount, an order or invoice number, are mapped field by field, so a file arrives in Amazon S3 already labeled and filed, and metadata captured against a stored file can create or update the matching record in SAP Business One. Changes on either side show up within seconds, with conflict resolution in place of nightly exports and manual filing.

The result is that a transaction and the document that backs it stay together. Finance, operations, and audit teams find the file behind a record without digging through folders, and the record in SAP Business One and the file in Amazon S3 never describe two different versions of the same document.

Common use cases

  • 01 Sync activities and service data with external support tools for teams that do not log into Business One.
  • 02 Two-way sync of business partners between SAP Business One and a CRM so sales edits and finance records converge on one customer master.
  • 03 Reconcile Object versions and delete markers into an audit table so teams track when files under a compliance prefix were added, replaced, or removed.
  • 04 Index every new Object's key, size, LastModified, and user metadata into a Postgres catalog table so applications query S3 contents in SQL instead of paging ListObjectsV2.

Common sync patterns

Where Amazon S3 captures inbound files: details reach the record

A contract, vendor bill, or receipt added to Amazon S3 with its details can create or update the matching record in SAP Business One, so a document captured outside the finance system still reaches the books.

An archive that stays current

As records change in SAP Business One, the corresponding files and metadata in Amazon S3 are kept in step, so a stored document reflects the latest version rather than a stale one-time export.

Audit-ready retention

Every transaction's supporting file lives in Amazon S3 beside its metadata, giving finance and audit teams a complete, searchable trail tied back to the record in SAP Business One.

What you can sync between Amazon S3 and SAP Business One

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.

Amazon S3 objects SAP Business One objects How this pairing syncs
Multipart uploads In-progress large-object uploads assembled from parts; objects above ~100 MB (required above 5 GB) are written this way, and incomplete uploads persist until completed or aborted. Journal Entries GL postings replicated for financial reporting. Multipart uploads is specific to Amazon S3 and Journal Entries to SAP Business One — each maps to any object or custom field on the other side.
Buckets Top-level, region-scoped containers that hold objects; enumerated to discover the namespaces and prefixes a sync should cover. Warehouses Stock locations that scope inventory quantities in item syncs. Buckets is specific to Amazon S3 and Warehouses to SAP Business One — each maps to any object or custom field on the other side.
Objects Files stored under a key; content is read with GET and written with PUT, and each object's key/size/ETag/LastModified is the unit indexed into a database. Price Lists Pricing data synced to quoting and e-commerce platforms. Objects is specific to Amazon S3 and Price Lists to SAP Business One — each maps to any object or custom field on the other side.
Object metadata System metadata (Content-Type, size, ETag, LastModified) plus user-defined x-amz-meta-* headers; user metadata is fixed at write time and only changeable by rewriting the object. Activities CRM-style tasks and interactions aligned with external sales tools. Object metadata is specific to Amazon S3 and Activities to SAP Business One — each maps to any object or custom field on the other side.
Object tags Up to 10 key-value tags per object, mutable in place via the tagging API independent of content, so classification and retention labels sync two-way without rewriting files. Business Partners Combined customer, vendor, and lead master records; the anchor object for most syncs. Object tags is specific to Amazon S3 and Business Partners to SAP Business One — each maps to any object or custom field on the other side.
Object versions When bucket versioning is enabled every write creates a new version ID; prior versions and delete markers are readable for history and audit syncs. Items Product master data including inventory levels, aligned with e-commerce and warehouse systems. Object versions is specific to Amazon S3 and Items to SAP Business One — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and SAP Business One

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.

Amazon S3 SAP Business One Sub-second propagation

DetectionAmazon S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications push object-created, object-removed, and object-tagging events to SNS, SQS, Lambda, or EventBridge.

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

SAP Business One Amazon S3 Interval-based propagation

DetectionStacksync polls SAP Business One for changes on an incremental schedule, reading only records changed since the previous pass. Polling on update timestamps.

DeliveryEach detected change is written to Amazon S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Amazon S3: S3 sustains at least 3,500 PUT/COPY/POST/DELETE and 5,500 GET/HEAD requests per second per partitioned prefix and scales higher automatically; bursts can return HTTP 503 SlowDown while it repartitions.

Change detection
S3 Event Notifications push object-created, object-removed, and object-tagging events to SNS, SQS, Lambda, or EventBridge; there is no modified-since query, so polling relies on each object's LastModified from ListObjectsV2
