From account analysis to OSS filing
From sales data to a filing-ready OSS return — without rebuilding it in Excel
REPOSS collects orders and invoices, reconciles overlapping sources, preserves and checks source VAT, converts original currencies with official ECB rates, and shows what must be resolved before you file with Skatteverket.

Illustrative figures, not a real filing.
The work you stop rebuilding
Your quarter should not begin with an account analysis
The required facts already exist in your sales and accounting systems. The expensive part is repeatedly extracting, matching, checking, converting and documenting them.
With REPOSS
- 01Collect detailed source records from a defined boundary
- 02Reconcile overlapping systems without mixing documents
- 03Send only incomplete or conflicting evidence to review
- 04Compile copy-ready EUR totals after preflight
- 05Freeze the filing package and later corrections
What you can answer
The questions a quarter actually turns on
Does the VAT in my source data agree with official reference rates?
REPOSS preserves the rate and amount your source reported, validates them, and exposes mismatches instead of silently rewriting filing facts.
When does the Swedish distance-sales threshold affect us?
REPOSS evaluates SEK 99,680 across the current and preceding calendar years while keeping threshold scope separate from OSS report scope.
Which transactions are not safe to include yet?
Missing destination, currency, classification, registration, or customer-location evidence becomes an actionable blocker before compilation.
Can we show where every filed figure came from?
Country totals remain linked to their source records, conversion evidence, validation outcome, and immutable filing package.
One evidence base, two better workdays
Built for the owner who needs certainty and the accountant who needs proof
For the business owner
See whether the quarter is healthy without learning another account-analysis routine. Know what is blocked, what it affects, and what to do next.
Less reconstruction. Earlier decisions. A visible path to filing.For the accountant
Review the source, reasoning and audit history behind a number instead of inheriting an unexplained spreadsheet at deadline.
Traceable evidence. Controlled exceptions. Reviewable handover.What it does
Built around the parts that actually take time
Source coverage you can prove
REPOSS records the import boundary, every completed flow, what was accepted or rejected, and whether the covered period is actually proven complete.
No double counting across systems
Reconcile a webshop order with its accounting invoice, choose the complete document that supplies filing values, and route disagreements to review.
An exception-first quarterly close
Preflight checks configuration, issues, reference data, registrations and customer-location evidence before REPOSS allows compilation.
Filing evidence designed to last
Filed reports are immutable. Later changes become correction events, while portal files, SAF-OSS and audit manifests preserve the trail.
How it works
From connected evidence to a reviewed filing package
Connect your sources
Set an explicit import boundary and connect the detailed order or invoice sources that hold the facts needed for OSS.
Review what needs attention
REPOSS reconciles duplicate representations, validates source VAT against official references, and sends incomplete evidence to one work queue.
Review, copy and preserve
Pass preflight, copy the country and rate totals into Skatteverket, confirm the external filing reference, and freeze the supporting snapshot.
Why not a spreadsheet
The same work, done three ways
| Capability | Spreadsheets | General accounting software | REPOSS |
|---|---|---|---|
| Source VAT and official-rate checks | Looked up by hand | Partly covered | Preserved and validated |
| Swedish OSS threshold evidence | Checked when remembered | Rarely included | Current and prior year evaluated |
| ECB conversion on the closing date | Entered manually | Entered manually | Fetched and applied |
| Order-level audit trail | Breaks as files are copied | Partial | Complete and exportable |
| Compiling the quarterly return | Rebuilt each quarter | Assembled by hand | One reviewed step |
A comparison of approaches, not of specific products.
Why the numbers remain defensible
Automation with deliberate stop points
REPOSS automates collection and calculation, but it fails closed when a filing fact is missing or contradictory.
Source facts stay source facts
Official rates validate source VAT; they never silently replace what the source reported.
Unsafe quarters do not compile
Preflight retains every actionable blocker until the underlying evidence passes validation.
Filed evidence does not move
A confirmed filing is immutable. Later adjustments are separate, append-only correction events.
Clear boundaries
What REPOSS does — and what remains yours
01Does REPOSS submit the OSS return to Skatteverket?
No. REPOSS prepares copy-ready portal values and supporting exports. You verify and submit them in Skatteverket, then record the external reference in REPOSS.
02Does REPOSS change the VAT charged by my source system?
No. Source-reported VAT remains the filing fact. Official VAT applicability is used for validation, and a mismatch becomes an issue to review.
03Which systems can REPOSS read?
The application contract covers Shopify, WooCommerce, Fortnox, Spiris and SIE 4. Provider availability is confirmed during onboarding while authorized-account launch certification is completed.
04How is the distance-sales threshold handled for a Swedish business?
REPOSS evaluates SEK 99,680 for the current and preceding calendar years, keeps threshold scope separate from report scope, and surfaces missing evidence instead of guessing.
05Does REPOSS provide tax advice?
No. REPOSS applies a documented reporting workflow and makes evidence reviewable. Your business and advisers remain responsible for the filing position and submission.
