When this situation arises

The month-end close is a company's early-warning system. When it is weeks late or does not happen at all, every decision is made on old numbers: budget, hiring, conversations with the bank and investors.

Typical signs: receipts pile up unprocessed, bank accounts are not reconciled, open items with customers and suppliers do not match, and the VAT return is based on incomplete data. Common causes are someone leaving the accounting team, fast growth without an extra hire, a system change or a new entity in the group.

The mistake made most often at this point: the team works through the old months – and creates the next backlog, because the current month is left lying.

What the interim CFO takes on

First, the stock-take: which months and accounts are open, which receipts are missing, which deadlines are fixed – investor report, bank reporting, VAT? In the first week this becomes a work plan with a realistic duration.

Then two separate tracks. Interim bookkeeping works through the open months in clearly defined packages: bank reconciliation, receivables, payables, accruals. The in-house team keeps the current month running. Where priorities, approvals or someone who owns the close are missing, an interim head of finance takes over close management.

The result is not just a cleared backlog but a close calendar with fixed dates and named cover – so the next backlog never builds up.

How it runs

Week 1: Stock-take

Record open months, accounts, receipts and reconciliations for each entity. Work through a sample, extrapolate the effort, note the fixed deadlines. Result: a work plan with duration and roles.

From week 2: Clear the backlog

Work packages by month and account area. The current month stays separately staffed. Missing receipts are requested, open questions tracked in a decision log.

In parallel: secure the current month

Once opening balances are right, the most recent month takes priority over the oldest – so investors and management see current numbers again quickly.

Afterwards: lock in the rhythm

Close calendar with working days, responsibilities and cover, ongoing account reconciliation, handover to the in-house team.

Frequently asked questions

How do I know the month-end close is behind?

When a month's numbers are only available after several weeks or not at all, bank accounts are not reconciled, and reports to investors or the bank rely on estimates.

How long does catching up take?

It depends on the number of open months, the quality of the receipts and the number of entities. The sample in the first week gives you a reliable range instead of a hope.

Is one extra bookkeeper enough?

If receipts and approvals are in place and only capacity is missing, yes. If decisions, priorities or someone who owns the close are missing, you also need a leadership role.

What happens to the VAT returns?

They continue and must be filed on time. If catching up shows that figures were wrong, the return is corrected – in agreement with the tax adviser.

What does it cost?

At nugrow, bookkeeping starts at EUR 850 per day excluding VAT, a head of finance is EUR 1,300 and CFO support EUR 1,800. Three days of bookkeeping a week over eight weeks makes 24 days, or EUR 20,400 excluding VAT.

How do we prevent the next backlog?

With a close calendar that assigns every task to a working day and a person, and with named cover for every key task.
