That's not an edge case. According to the CBS the Netherlands has nearly 300 thousand family businesses, and the vast majority of them have fewer than ten employees. In a business like that, there is often only one person who knows how things really work. If that person is the owner who leaves, the shares transfer a business that loses half its knowledge on the day the deed is signed.
When should you start knowledge transfer during business succession?
Around a handover, a line of advisers stands ready: an accountant for the valuation, a tax specialist for the business succession scheme, a notary for the deed. All useful, and all busy with what you can write down. None of them is responsible for the question why customer Van Dijk has received four percent discount since 2014, which machine you adjust by ear, or which supplier you should call if the standard route gets stuck.
That knowledge isn’t recorded in any deed, included in any valuation, or transferred with the business. You see the consequences in the first year after the handover: the successor calls the former owner six to nine times a week with a question nobody else can answer. At twenty minutes per question, that’s two to three hours a week — for a whole year. That’s not a handover; it’s a subscription.
The honest test: Could the departing owner take two weeks off today without their phone? If not, the business isn't transferable yet — no matter how tidy the shareholding structure looks on paper.
Type over this order number. Once is doable. Forty times a day, every day, is a job.
Knowledge for family business succession: what isn't documented anywhere
Before you can transfer anything, you need to know what you're transferring. In practice it's about five types of knowledge, each with a logical place in the systems you already have — automatically capture knowledge through integrations makes sure that keeps happening automatically. What a Bedrijfsgeheugen precisely is and why SME businesses lose knowledge without noticing we explain in the pillar article; below is what needs to be arranged first when handing things over.
| Type of knowledge | Where it is now | Where it belongs | Lead time |
|---|---|---|---|
| Customer and pricing agreements | The owner's head and inbox | Customer record in AFAS or Exact Online, including the reason behind it | 4 weeks |
| Production and service work instructions | Experience, watching over someone’s shoulder, “that’s how we do it” | Short instructions and videos in SharePoint or Teams | 8 weeks |
| Suppliers and purchasing terms | Filing cabinet, scattered emails, phone numbers on one device | One file per supplier, with terms and a contact person | 3 weeks |
| Decisions and the reasoning behind them | Nowhere | Decision log: date, decision, reason, in one document | Ongoing |
| Access, accounts, and licenses | Owner's personal email address | Business accounts in Microsoft 365, two-step verification enabled | 2 weeks |
The fourth row is the hardest and most important. You can look up a pricing agreement; the reason it was made in the first place disappears with the person who was there. And that’s exactly the reason the successor needs when the customer asks if the price can be sharpened a little.
What does it cost if the knowledge doesn’t transfer?
Work it out for a family business with 18 employees. The departing owner remains available one day a week as an adviser after the handover. Eight hours per week, 45 weeks, at € 90 per hour: € 32.400 in the first year. If it stays for two years — which happens more often than planned — you’ll be over € 60.000, and the successor still won’t have learned to make decisions independently.
The alternative: twelve two-hour sessions in which you document the ten most important topics. That's 24 hours from the previous owner and 24 hours from someone documenting it. At an internal hourly rate of € 45, that's € 2.160, plus some time to keep it up to date. The same knowledge, at one-fifteenth of the cost, and afterwards it’s stored somewhere the third generation can still access. If you’d like to automate capturing some of this, then what an AFAS partner costs a useful point of comparison alongside this calculation.
Then there are the costs that never show up on an invoice: customers who leave because their usual point of contact is gone, quotes that are left hanging because no one feels responsible—see follow up on quotes without a CRM for the calculations behind them — and a successor who spends months discovering what could have been documented long ago.
The way it works now
- The appointment is in one colleague's mailbox
- Data is manually retyped from one system to another
- The person who knows is on vacation
- No one can see afterwards why this decision was made
As it is
- The agreement is stored with the client, findable for everyone
- Once entered, information flows through to the rest
- Work continues, even if someone is absent
- Every decision has a source, an owner, and a date
Hand over the company’s memory in five steps, over twelve months
You don't need to buy a new system for this. The knowledge should end up in AFAS, Exact Online or Microsoft 365 — the packages you already have. This sequence works:
- Month 1: create the single-person list.Go through every recurring task and write down who can do it. Any task with exactly one name next to it is a risk. There are usually between 15 and 30 tasks, and a third of them have the owner's name next to them.
- Months 1–2: rank by revenue risk, not by convenience.Which five tasks would bring the business to a standstill if the people doing them left tomorrow? Start there. The rest can wait or never get done, and that’s fine.
- Months 2–6: document one topic per week.Have the owner explain how something works out loud for two hours, record it in Teams, and have it draft an instruction. Microsoft Copilot turns a recording like that into a first draft; someone else removes the errors. Talking meets with less resistance than writing.
- Months 4–9: switch roles.The successor actually does the work—quotes, pricing discussions, supplier negotiations—while the previous owner observes without taking over. Mistakes at this stage are cheap; mistakes after the handover aren’t.
- Months 9–12: run the vacation test.The outgoing owner is unreachable for two weeks. Everything that goes wrong is a gap in your business memory that you can still close before the deed is signed.
Make sure documentation doesn't become an extra task, or it will fall by the wayside within a month. When a request from your website automatically becomes a customer record and the quote follows up on itself, the information gets recorded along the way. That's exactly what integrating systems in SMEs delivers, and why Connect AFAS and Exact is worth more at handover than the retyping it saves.
What a buyer or successor asks for first
If the successor comes from outside the company, the points above suddenly come under intense scrutiny. During due diligence, a buyer routinely asks about customer contracts, supplier terms, open quotes, and how dependent the business is on the owner — points that come up in every due diligence checklist come back. "It’s not that bad" is not an answer to that last question.
What does help: a customer database where agreements are recorded instead of buried in an inbox, work instructions someone else can follow, and a decision log showing why the margin is what it is. This not only shortens the investigation; it also removes the main reason to make part of the purchase price contingent on results after the handover. If you’re not there yet, then what digitalization costs for SMEs a useful second calculation alongside the valuation.
Know how much of your business is in one person’s head?
Take the free self-assessment and see in two minutes where your business depends most on one person — from customer appointments to planning and quotes.

The report is yours, even if you decide to continue on your own.
Frequently asked questions
When should you start transferring knowledge as part of business succession?
Twelve to eighteen months before the intended handover date. The legal and tax side can be wrapped up in three to six months, but transferring knowledge takes repetition: someone needs to do the work themselves for a full season before it sticks. If you wait until the deed is in sight, the former owner will inevitably end up as an adviser for another year.
What do you do if the departing owner doesn’t want to document anything?
Don’t ask people to write; ask them to talk. Two hours explaining things aloud with a recording is more valuable than three months of pushing for a document. Often, it’s not unwillingness but discomfort: documenting knowledge can feel like making yourself redundant. So call it handing down the craft, not handing over power.
Do we need a new system for this?
No. In almost every family business the knowledge is already partly in AFASDutch ERP package for administration, HR and payroll. Many SMBs have their single source of truth in it., Exact Online or Microsoft 365 — just fragmented, and the most important part is nowhere. You need agreements about where what belongs and a few connections so that recording happens automatically, not a new package that nobody opens.
How do you document knowledge without spending months writing?
Work in two-hour blocks, one topic per week, and accept a version that’s 80 percent right. A short set of instructions with four steps, ready today, is worth more than a handbook that might be finished next year. Have the person who’ll use it review the text: they’ll spot what’s unclear straight away.
Will things change if the successor comes from outside the family?
The sequence stays the same, but the urgency is greater. A son or daughter has been watching unconsciously for years and already knows the customers to some extent; an external buyer starts from zero and factors the lack of documented knowledge into the price or terms. So with an external transfer, you start earlier, not later.
