Why teams connect Amazon S3 and Unleashed Software

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

Unleashed Software runs the business on structured records: Customers, Suppliers, Warehouses, Stock Adjustments. 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 Unleashed Software 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 Unleashed Software 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 Customers, Suppliers, Warehouses, Stock Adjustments in Unleashed Software 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 Unleashed Software. 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 Unleashed Software and the file in Amazon S3 never describe two different versions of the same document.

Common use cases

  • 01 Keep Products and pricing aligned between Unleashed and accounting or PIM systems.
  • 02 Mirror Purchase Orders and supplier data to a data warehouse for procurement reporting.
  • 03 Two-way sync Object tags with a database so retention or classification labels set in an internal app write back onto S3 objects via the tagging API without rewriting the files.
  • 04 Mirror Objects under a given Bucket and prefix into another bucket, region, or a warehouse external stage for backup or downstream processing.

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 Unleashed Software, so a document captured outside the finance system still reaches the books.

An archive that stays current

As records change in Unleashed Software, 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 Unleashed Software.

What you can sync between Amazon S3 and Unleashed Software

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 Unleashed Software objects How this pairing syncs
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. Stock On Hand Quantity and value per product per warehouse; the read source for availability syncs. Object versions is specific to Amazon S3 and Stock On Hand to Unleashed Software — each maps to any object or custom field on the other side.
Prefixes (folders) Logical path segments in object keys used to scope a sync and to parallelize throughput, since S3 rate limits partition by prefix. Sales Orders Outbound orders with lines, status, and fulfillment detail; a common write target from storefronts and CRMs. Prefixes (folders) is specific to Amazon S3 and Sales Orders to Unleashed Software — each maps to any object or custom field on the other side.
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. Purchase Orders Inbound supply orders synced for procurement visibility. Multipart uploads is specific to Amazon S3 and Purchase Orders to Unleashed Software — 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. Customers Buyer records with pricing tiers and delivery addresses. Buckets is specific to Amazon S3 and Customers to Unleashed Software — 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. Suppliers Vendor records referenced on purchase orders. Objects is specific to Amazon S3 and Suppliers to Unleashed Software — 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. Warehouses Stock locations that scope inventory quantities and order fulfillment. Object metadata is specific to Amazon S3 and Warehouses to Unleashed Software — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and Unleashed Software

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 Unleashed Software 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 Unleashed Software through its API, with automatic retries and rate-limit backoff.

Unleashed Software Amazon S3 Interval-based propagation

DetectionStacksync polls Unleashed Software for changes on an incremental schedule, reading only records changed since the previous pass. Polling with modified-date filters on list endpoints.

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.
  • Unleashed Software: Subject to the platform's API rate limits; paginate list endpoints and batch where possible.
