3.6.4May 18, 2026

IOSS Monthly Summaries

3 changes
Feature2 items
  • Filing Prep and Multi-jurisdiction now show real IOSS month summaries built from committed imported-goods events, with month statuses, totals, included counts, and warning categories instead of placeholder states
  • The reporting APIs now apply the EUR 150 intrinsic-value ceiling, excise exclusion, registration-window checks, and month-end ECB conversion when preparing IOSS month totals
Improvement1 item
  • Imported-goods rows excluded from Union OSS are now surfaced with explicit IOSS monthly warnings and counts so merchants can see whether a month is ready, nil, blocked, or still needs review
3.6.3May 17, 2026

OSS Overview Data Source Alignment

3 changes
Fix2 items
  • The OSS Overview now reads threshold progress from the committed compliance ledger, so merchants with filing-ready supply data no longer see an empty threshold position just because legacy calculation logs are absent
  • Supporting evidence on the overview now comes from committed classified supply events and explains that the threshold uses a narrower eligible slice than the broader activity totals shown for context
Improvement1 item
  • Daily threshold alerts now use the same underlying compliance data source as the dashboard, reducing mismatches between the OSS Overview, in-app alerts, and email notifications
3.6.2May 16, 2026

OSS / IOSS Filing Prep Workspace

3 changes
Feature2 items
  • Added a new Filing Prep workspace under Compliance that combines quarter deadlines, registration coverage, Union OSS readiness, and quarter-scoped IOSS monthly review context in one account-level view
  • Added an authenticated filing-prep API that reuses the existing Union OSS preview logic while returning registration-required or missing-rate blockers as explicit readiness states instead of raw preview errors
Improvement1 item
  • The new workspace links directly into OSS Quarterly Summary, Accountant Format, Country VAT Breakdown, Multi-jurisdiction, Exports, and OSS / IOSS Registrations so merchants can move through filing review without hunting through the dashboard
3.6.1May 13, 2026

OSS Overview & Registration Guidance

5 changes
Feature2 items
  • The OSS Overview now understands Union OSS registration coverage, so exceeded turnover is shown as managed when an active Union OSS registration is already on file
  • The dashboard now gives merchants a direct shortcut into OSS / IOSS Registrations when the threshold is exceeded but no active Union OSS registration covers the account
Improvement2 items
  • Unread threshold alerts are surfaced in context on the OSS Overview page and still open through the existing notification bell in the top bar
  • Registration summaries now ignore unresolved overlapping rows when showing active coverage, reducing false confidence from duplicate records
Fix1 item
  • Overlapping or duplicate registration rows are easier to clean up: the page highlights conflicts and explains when to use Excluded versus Ended
3.6.0May 13, 2026

Marketing Page Performance & Accessibility

4 changes
Improvement4 items
  • Improved color contrast across homepage badges, stat tiles, step markers, and decorative numbers so the public site meets WCAG accessibility expectations on both light and dark sections
  • Reduced first-paint time on the homepage by inlining the critical stylesheet, eliminating an extra round-trip on first visits
  • Tuned client-side bundling for the public marketing pages so unused code from heavier libraries is not shipped to visitors
  • Removed an unused legacy font asset that was no longer needed after the move to a platform-managed font
3.5.9May 11, 2026

Public Site Refresh

3 changes
Improvement3 items
  • Refreshed the public site with a more expressive homepage, stronger color palette, and clearer storytelling around VAT calculations, compliance, and launch readiness
  • Redesigned the main navigation and footer so documentation, sign-in paths, and launch actions are easier to find from every public page
  • Updated the Privacy Policy and Terms pages with clearer, more current service language
3.5.8May 7, 2026

OSS / IOSS Multi-jurisdiction Reporting

4 changes
Feature2 items
  • Added a Multi-jurisdiction dashboard report that shows Union OSS Member State of consumption exposure, preserved return sections, due dates, and source-event counts for a selected quarter
  • Added an authenticated multi-jurisdiction API that reuses the existing Union OSS filing-prep preview rules and now includes month-scoped IOSS review data alongside the quarterly exposure view
Improvement2 items
  • Imported-goods rows detected during the Union OSS quarter preview are now surfaced as IOSS data awaiting the monthly engine instead of being lost inside generic unsupported-supply warnings
  • The new report keeps OSS/IOSS period cadence explicit: Union OSS remains quarterly and IOSS remains monthly with end-of-following-month due dates
3.5.7May 7, 2026

Union OSS Accountant Format

4 changes
Feature2 items
  • Added a dedicated Accountant Format dashboard page for Union OSS quarter review, combining manifest assumptions, filing context, summary lines, and country regrouping in one accountant-readable layout
  • Added an authenticated accountant-format API for Union OSS that reuses the existing filing-prep preview logic while emitting export-safe major-unit amounts and percentage VAT rates
Improvement2 items
  • The new filing context now shows the statutory due date and only treats a quarter as a nil-return candidate when zero source events were recorded, avoiding silent nil-return assumptions for excluded or review-needed rows
  • The accountant-format view keeps the existing CSV and JSON export package separate while giving accountants a faster on-screen review surface before download or later filing workflows
3.5.6May 6, 2026

Union OSS Reporting Previews

5 changes
Feature2 items
  • Added dedicated OSS Quarterly Summary and Country VAT Breakdown dashboard pages for reviewing a Union OSS quarter by return section, Member State of consumption, and return-currency totals
  • Added authenticated preview APIs for the Union OSS quarterly summary and country VAT breakdown, backed by the same filing-grade classification and warning rules
Improvement3 items
  • The existing Country Exposure page remains available as analytics, while the new period-driven OSS previews now cover filing-oriented quarter review
  • Expected preview blockers, such as missing Union OSS registration coverage or quarter-end exchange rates, now stay inside the dashboard UI instead of surfacing noisy browser errors
  • Blocked previews no longer keep retrying in the background and now explain the specific prerequisite that must be fixed before the quarter can be reviewed
3.5.5May 4, 2026

Managed Source Catalog Foundation

5 changes
Feature2 items
  • Added a dedicated Sources dashboard page for registering stores and channels, reviewing unregistered source tags, and editing source profile metadata without changing historical transaction rows
  • Added authenticated source management APIs so integrations can list, register, update, and review source profiles directly
Improvement2 items
  • Transaction Ledger and Exports now use searchable source selectors backed by managed profiles plus unresolved raw tags, and Ledger rows show mapped labels alongside raw source keys
  • Developer docs and OpenAPI now document the Sources API alongside the existing X-Source-ID capture flow on VAT calculations
Security1 item
  • Source profile mutations now flow through CSRF-protected, rate-limited dashboard proxy routes, while backend handlers enforce account scoping, validation, and active-profile caps
3.5.4May 4, 2026

Multi-Store Reporting Plan

3 changes
Improvement2 items
  • Documented the next multi-store and multi-channel reporting phase: current Source ID tagging stays supported, while managed source profiles, channel labels, marketplace metadata, and searchable source filters are planned next
  • Developer docs now explain how to pass X-Source-ID on VAT calculations and how source_id filters affect transaction list, export, and aggregation endpoints
Security1 item
  • Source-profile planning now includes account-level authorization, resource caps, audit logging, and guidance to keep personal data and secrets out of source tags
3.5.3April 30, 2026

Reporting Filter Refinements

6 changes
Improvement6 items
  • Transaction Ledger and Exports now use searchable dropdown filters for country, currency, tax class, and API key instead of requiring users to type identifiers manually
  • Ledger filters are preserved when moving to CSV export, keeping export scope aligned with the rows users were reviewing
  • Monthly Trend now uses active-month comparisons and totals so inactive months no longer read like real revenue drops
  • Transaction Ledger request IDs are easier to copy when matching a row to API requests or backend logs
  • Tax Class Mix now uses normalized all-currency totals, catalog labels, compact metrics, ledger drill-down links, accessible share indicators, and a cleaner breakdown table instead of clipped donut labels
  • Source ID remains a bounded text field for integration-defined store or channel tags that do not have a shared catalog yet
