The digital link, explained
What HMRC actually requires from spreadsheets under MTD
There is a widespread myth that Making Tax Digital bans spreadsheets. That is completely untrue. HMRC permits spreadsheets, provided they connect to HMRC using digital bridging software without manual copy-pasting.
Keep the transfer digital
Once your records are digital, transfer figures between your spreadsheet and MTD software electronically, rather than copying and pasting or manually retyping totals.
Avona creates the digital link
Our ingestion engine reads your file cells directly, maps your totals to HMRC’s categories, and submits the quarterly summary via official APIs without altering your original workbook.
Bring the files you already use
Four flexible ways to import your financial records
Whether you run a tidy workbook or have a folder of downloaded PDF statements, Avona handles the data structuring for you.
Excel & CSV dynamic mapping
Upload your workbook. Our intelligent column mapper automatically detects dates, payment descriptions, gross receipts, and expense columns without forcing you into rigid templates.
Digital PDF statement parsing
Downloaded your monthly PDF statements from your bank? Drop them directly into Avona. Our system extracts transaction tables, strips out headers and footers, and structures the records into an MTD cashbook.
Smart receipt OCR
Snap physical receipts or trade counter invoices on your phone. Optical character recognition extracts supplier names, dates, amounts, and VAT breakdowns automatically.
Pre-submission error audit
Before transmitting data to HMRC, Avona AI scans your uploaded records for duplicate transactions, missing dates, unallowable expense items, and mathematical discrepancies.
