I issued an invoice with a future date and now I can't issue an invoice with an earlier date (date locked in the sequence)

If you issued an invoice with a future date, you may no longer be able to issue invoices with an earlier date in that sequence. Here is why and how to fix it. 📅

❓What is happening

When you try to issue (or finalize) an invoice with an earlier date, the system does not allow it and keeps the most recent date. This often happens after a document was issued by mistake with a future date, and it continues to happen even after that document is cancelled.

📜Why this happens

This is a Tax Authority rule: within the same sequence, the date of each document must be equal to or later than the date of the last document already issued in that sequence. In other words, numbering and dates must follow chronological order.

So if the last document in the sequence has a later date (for example, 29/07), it is no longer possible to issue new documents in that sequence with an earlier date (for example, today's date).

1How to fix it: create a new sequence

The correct way to resume issuing with the intended date is to create a new sequence, which starts without any date restriction:

1. Go to Settings → Sequences/ATCUD;
2. Click Create New Sequence, give it a name (for example, 2026B) and save;
3. Set that sequence as the default sequence for issuing documents;
4. When creating the invoice, select the new sequence. You can now use the intended date.

✅Best practices to avoid this

• Always check the document date before finalizing, especially if you often invoice around the end or start of the month.
• Remember that once a document is finalized, its date sets the minimum date for the following documents in that sequence.

💬 Frequently asked questions

❓ Why can't I issue an invoice with an earlier date in my sequence?

This is a Tax Authority rule: within the same sequence, the date of each document must be equal to or later than the date of the last document already issued in that sequence.

❓ Does cancelling the future-dated invoice fix the problem?

No. A cancelled document remains in the sequence and in the SAF-T file, so its date still counts as the sequence's reference.

❓ How do I resume issuing documents with the date I need?

Create a new sequence, set it as the default sequence, and select it when creating the invoice. You can then use the intended date.

❓ How can I avoid this problem?

Always check the document date before finalizing, since once a document is finalized, its date sets the minimum date for the following documents in that sequence.
