Procedure

Here’s how we proceed

  1. Backlog check

    We review bank accounts and existing accounting records to identify what is missing or has been posted incorrectly. We forward correspondence from the tax office to your tax advisor without reviewing it. You’ll receive a brief report listing the open months, accounts, and receipts.

  2. Plan and fixed price

    You receive a timeline based on urgency and a fixed price per month posted.

  3. Upload documents once

    You upload bank statements, receipts, and existing DATEV data to the client portal. We’ll request anything missing in batches, not one receipt at a time.

  4. Post entries and reconcile

    We post month by month and reconcile bank, cash, and open items, with every correction flagged and justified. Corrections in years with completed financial statements are posted only as directed by the tax advisor. Closing and opening entries are not included; the tax advisor handles those.

  5. Closing with the tax advisor

Price

What it costs

After the backlog check, you’ll receive a fixed price for each month we catch up. For corrections to existing entries, we set out the price in your quote. All prices are net, plus VAT.

One year usually takes two to four weeks once we have all the bank statements.

Switching

Switch bookkeepers without interruption

For the switch, all we need from you is a signature. We’ll request the data and DATEV records from your previous advisor and continue posting entries seamlessly.

  1. Online quote and contract

    You’ll answer a short questionnaire and sign digitally.

  2. Authorization to request data

    The authorization is already part of your contract documents. You end the contract with your previous advisor yourself, using a short sample letter we provide.

  3. We’ll retrieve the data

    We request the chart of accounts, balances, open items, and the DATEV records. For payroll, we also obtain the figures for the current year.

  4. Reconcile opening balances

    We’ll check whether the bank balances, open items, and account balances match up, and point out anything that stands out.

  5. Continue posting

    From the agreed month, we handle your bookkeeping, with no gaps in bookkeeping or payroll.

When to switch?

The easiest time is at the start of a new month or quarter. It’s also possible to switch in the middle of the year. If your previous advisor has months of unprocessed records, we’ll process them as part of our catch-up bookkeeping.

What switching costs

We’ll include the cost of taking over from your previous advisor in your quote.

Any outstanding invoices with your previous advisor should be settled beforehand; otherwise, the handover may be delayed.

Questions

Frequently asked questions about catch-up bookkeeping and switching

Is a bookkeeping firm allowed to post entries for past years?

Yes. Catching up means recording current business transactions, expressly without closing and opening entries. The tax advisor handles those entries, financial statements, and tax returns.

Do I need every receipt?

No. We start with the bank statements and only request receipts that are actually missing for the bookkeeping.

The tax office has issued an estimated assessment. What now?

We’ll enter the actual figures and forward the notice to the tax advisor without reviewing it. On this basis, the tax advisor considers an objection or an amended return.

Can I continue posting entries myself afterward?

Yes. We’ll provide you with the chart of accounts, posting rules, and a brief orientation.

Do I have to end my contract with my tax advisor?

Only for the tasks we’re taking over. If you’d like to keep your tax advisor for financial statements and tax returns, we’ll work with them.

How long does the transition take?

Usually one to three weeks, depending on how quickly your previous advisor releases the data.

What if the previous advisor doesn’t respond?

We’ll send them a written reminder. Until the data arrives, we’ll continue posting entries based on your bank statements. Your tax advisor will clarify which tax deadlines are approaching.
