Can I close the Sales Ledger or Purchase Ledger separately from the Nominal Ledger?

iplicit does not support closing the Sales Ledger or Purchase Ledger separately from the Nominal Ledger. Financial periods apply across all ledgers at once. You can, however, set specific document types - such as invoices - to default to a later period, while a prior period stays open for Nominal Ledger adjustments. This article explains the behaviour and how default posting periods let you manage each ledger separately without closing it.

Why iplicit works this way

Period closure in iplicit applies at the financial period level, not at the ledger level. This keeps the Sales Ledger, Purchase Ledger and Nominal Ledger aligned, so transactions can't be posted to inconsistent periods across different areas of the system. There is no option to close a single ledger independently.

If a prior period is open for Nominal Ledger adjustments, it's also open for Sales Ledger and Purchase Ledger posting, unless default posting periods are set to redirect where documents land.

Managing ledgers separately without closing them

Since the release in July 2026, Financial Year Groups support independent default posting periods for the Sales Ledger and Purchase Ledger, alongside the existing default period for everything else. This lets you move each ledger's default period forward at a different pace - for example, holding the Sales Ledger and Nominal Ledger in August while moving the Purchase Ledger default on to September once it's finished for the month - without closing any period.

This only affects document types set to use the Financial Year Group default period for their minimum posting period. Document types left on 'Open periods' will use the first open period instead.

Full setup steps are covered in a dedicated article, see 'How to set default posting periods for the Sales Ledger and Purchase Ledger'.

Things to know

• This applies equally to the Sales Ledger and the Purchase Ledger. Both follow the same period rules as the Nominal Ledger
• If you need a prior period fully closed to all new Sales Ledger and Purchase Ledger documents, close the period in the usual way. This also closes it for Nominal Ledger adjustments
• Default periods only govern documents defaulting to a period based on the document date. They don't override a period that's genuinely closed.
