About this Gig
Need to check invoice data before your next processing step? I will validate a batch of plain UTF-8 text invoices and return JSON/CSV results with an exception report.
This service accepts only the two documented text layouts, Layout A or B. Send a sanitized sample before ordering so I can confirm that it fits. PDFs, scans, images and OCR are not included.
The offline pipeline checks required fields, normalizes dates and amounts, flags duplicates and applies documented consistency rules. Exceptions include reasons for review; unsupported inputs are not silently treated as valid.
You receive the processed outputs and a report of detected exceptions for the agreed batch. Packages cover up to 25, 100 or 500 documents; each file must be no larger than 100,000 bytes.
The studio reference pipeline passed a separate internal QA review with 104 tests. This is reference evidence, not a result already achieved on your files.
No accounting posting, tax advice, bookkeeping or live integration. Message with a sanitized sample, document count and required output. I will confirm layout fit, acceptance checks and availability before purchase. Do not send credentials.

FAQ
What exactly do I send you?
Send UTF-8 text invoices, max 100,000 bytes each. Layout A uses INVOICE / LINE ITEMS and YYYY-MM-DD dates. Layout B uses #HEADER / #ITEMS / #TOTALS and MM/DD/YYYY dates. Message for the full layout spec and a sanitized sample fit check before ordering. No PDF, OCR, scans, spreadsheets or images.
Do you ever need my API keys, database, or live-system access?
No. This Gig has no configuration surface for credentials. Everything runs offline against only the file(s) you send.
Can this read scanned invoices, photographed receipts, or handwriting?
No. This is not OCR and does not parse PDFs or images. A document in any other format is rejected as UNSUPPORTED_LAYOUT, never guessed at on a best-effort basis.
What if my invoices don't match either documented layout?
Message me a sample first. If your export is a close variant, I can confirm fit before you order. A genuinely new layout is a separate scoped change order, not a silent best-effort parse.
What happens to a document with a math error or a missing field?
It's rejected with one specific, closed-vocabulary reason code (for example RECONCILE_FAIL_R2 or MISSING_REQUIRED_FIELD) in the exception report - never silently dropped, never a generic "failed."
Does this claim to be defect-free or independently certified?
No. The package passed two independent reality reviews with no unresolved high- or medium-severity defect. One disclosed low-severity item remains: an interrupted run can print a raw rather than clean error message. It never corrupts or loses data and is documented in delivery notes.
Will you post results into my accounting system or process payments?
No. You receive structured files (JSON/CSV) and a report. Posting to an ERP, ledger, or payment system is out of scope and never happens automatically.
Can I verify nothing changed after delivery?
Yes. Every delivered file's sha256 is listed in the evidence map and can be checked with a standard checksum tool. I also re-run your batch in a second clean environment before delivery and confirm both runs produce the same hash. That seller-side reproducibility check is included with every order.
What if my batch has zero errors?
Then the exception report says zero. Findings are derived only from your submitted documents - never manufactured to justify the order.
Is this tax, legal, or compliance certification?
No. The reconciliation checks are arithmetic - do the numbers your own documents state actually add up - not a determination of tax correctness, legal enforceability, or regulatory compliance.
