Document ↔ myDATA record
Joined when they share the same supplier ΑΦΜ, series, number and invoice date, or when you uploaded the document from an AADE has it row. A sales record is never joined to a purchase document.Payment out ↔ purchase invoice
- The amounts must be exactly equal, to the cent. A bank fee taken off breaks the match.
- The invoice date must be between 62 days before and 5 days after the bank date.
- The invoice must not already have a payment, and must be on the same client as the statement.
- There must be exactly one candidate. Two invoices for the same amount in the window → neither is matched.
Receipt in ↔ sales invoice
- Amounts within €0.01.
- Same date window (62 days before to 5 days after).
- Cancelled invoices are never matched.
- Several candidates: the one whose MARK or series-number appears in the bank reference wins; otherwise nothing is matched.
- If an equal and opposite bank line exists within 14 days, it’s treated as a bounced payment and not matched.
Books (ERP) entries
Match on ΑΦΜ, amount within €0.50 and date ±5 days, only when exactly one fits.ΑΦΜ and names
Spaces, dashes and a leading EL are ignored. Leading zeros are not — 012345678 and 12345678 don’t match. Company names are compared without punctuation and without the legal-form words (ΑΕ, ΕΠΕ, ΙΚΕ, ΟΕ, LTD, SA…).Partial payments, instalments, one payment for several invoices
These are never matched automatically. TaxLayer suggests them as a row ending Is that right? and you confirm with Yes, that’s right:- Short or over payment — one receipt between 50% and 110% of the invoice that names the invoice. A 0.1–2% shortfall is treated as a bank fee.
- Instalments — 2 or 3 receipts adding up to one invoice within €0.02.
- One payment, several invoices — one receipt equal to 2 or 3 open invoices within €0.02.
- Withholding — a receipt equal to the invoice less declared withholding, within 90 days.
Credit notes and cancellations
A credit note is linked to the invoice it names; nothing is netted off automatically. A cancelled invoice is never matched to a payment and is dropped from AADE has it, you have no copy.The grace period
For 21 days after an invoice date, a missing payment or a missing AADE filing is too early to chase and sits under Nothing needed. After that it becomes an exception.Checklist when an item won’t match
- Do the amounts differ at all (money out) or by more than €0.01 (money in)?
- Is the bank date more than 62 days after, or more than 5 days before, the invoice?
- Are there two invoices for the same amount in that window?
- Does the invoice already have a payment?
- Is the statement on a different client from the invoice?
- Is the ΑΦΜ written differently (missing leading zero, foreign prefix on one side)?
- Is it a credit note, or cancelled in myDATA?
- Is it a partial or multi-invoice payment? Look for a suggestion row.
