When you are switching accountants, what is it you are actually afraid of?
Most owners who want to change providers stay put another year. The reason is rarely loyalty. It is the fear that something will go missing, a deadline will slip, and the mess will land on their desk.

When you are switching accountants, the decision usually isn’t hard. You already know the numbers arrive late, or the questions go unanswered for a fortnight. What stops people is the imagined cost of moving: chasing files, explaining the business from scratch, a VAT return falling through the gap between two providers.
My view, after running handovers as the receiving side, is that the disruption people fear sits almost entirely in one place. It is the part where the client is asked to project-manage the move. Take that away and the rest is routine correspondence between two professionals.
So this is a piece about what actually breaks during a change of provider, what doesn’t, and what a managed handover removes from your desk. Ardein does this at no separate charge, which colours my opinion, and I’d rather say so.
The disruption you imagine and the disruption that happens
The picture in most owners’ heads is a month of chaos. What I see is narrower and duller than that.
Real friction shows up in three places. Records arrive incomplete, so the opening balances need rebuilding rather than importing. Software access is tangled, with the outgoing provider holding the subscription. And the timing lands badly, with a return due inside the fortnight the move takes.
What almost never happens is the thing people dread most: a filing missed because nobody was watching. Responsibility for deadlines is agreed in writing at the start, and until the new agent is authorised with HMRC the old arrangement still stands. Nobody drops the baton by accident, because the baton is held by two hands for a while.
So the honest answer is that a change of provider costs you a couple of hours of attention, spread over a few weeks, if someone else is running it. If nobody is running it, it costs you a year of putting it off.
What a managed handover takes off your desk
A managed handover means the receiving accountant does the work of collecting what is needed. You sign two or three things and answer questions about your own business.
Here is what Ardein runs on your behalf:
- The professional clearance letter to your current provider, and the follow-up when it goes quiet.
- The list of records requested, which is longer than most people expect: trial balance, ledgers, payroll data, fixed asset register, capital allowance pools, software backup.
- Agent authorisation with HMRC for the taxes we are taking on.
- A written map of who is responsible for what, from the date of the switch until the first month-end under the new routine.
- A transition plan built around your year end and your next VAT quarter, so the move lands in the quiet part of the cycle.
The handover is managed by Ardein at no separate charge. That is deliberate. Charging for the handover would mean charging you for the one part of the arrangement you get no benefit from.
The risk of staying put isn’t a lost file during a transfer. It’s another year of decisions made on records that nobody has read closely enough to question.
Why the records you receive decide everything after
The handover pack is not an administrative formality. It is the foundation of every report you will read for the next three years.
What arrives is often thinner than it should be. A set of filed accounts and a software login, with no working papers behind them. That is enough to file again next year. It is not enough to tell you whether last month was profitable.
This is where the questioning matters. Rebuilding a chart of accounts in Xero for one owner-managed business surfaced twenty thousand pounds of goods supplied and never invoiced, found by reconciling the sales ledger against delivery records. Nobody was hiding it. The records were simply never read closely enough for anyone to notice.
So when someone asks me what the real risk of staying put is, that is my answer. The risk is not a lost file during a transfer. It is another year of decisions made on records nobody has checked properly. Moving provider is the only time anyone opens the bonnet.
When to move, and when to wait
The timing question comes up in every first conversation, so here is where I land on it.
The cleanest moment is shortly after a year end has been filed. The historic position is settled, the new provider starts with a closed set of books, and there is no argument about who completes what.
The second cleanest is the start of a VAT quarter. You avoid splitting a return between two sets of records.
What I would not do is wait for a perfect window that is eleven months away. If the numbers are already late and the queries already unanswered, another year of that costs more than a slightly awkward transfer. Mid-year moves are ordinary work. The opening balances take a little longer to establish, and that is the whole of it.
The one situation where waiting is right is when something significant is mid-flight, a funding application being assessed or an enquiry open with HMRC. Finish that, then move.
What the first ninety days should look like
A handover that ends when the files arrive isn’t finished. The point of moving is what happens next.
Ardein runs a defined ninety-day onboarding. Month one is foundations: bookkeeping brought complete and accurate, banks reconciled, supplier and customer balances made to make sense, and a written agreement on who does which part of the finance process. Month two is routine: bookkeeping, supplier bills, credit control, payroll and reporting all on a fixed rhythm, with checks introduced where they were missing.
By the end of month three the finance function runs to an agreed timetable. You get monthly management information on cash, debtors, creditors and performance, delivered on the same date each month, provided the information is with us.
That is the measure I would hold any new provider to. Not how quickly they collected the files, but whether, ninety days in, you can answer a question about your own business without ringing anyone.
Common questions
Do I have to tell my current accountant myself before anything starts?
You write once to confirm you are moving and that they may release information to us. That is usually a short email. Everything after it, the clearance letter, the records request, the follow-ups when replies are slow, is handled by Ardein. You are not asked to negotiate anything on our behalf.
What happens if my current provider is slow to release the records?
It happens, and it rarely stops the move. We chase directly, and in the meantime we can rebuild a working position from bank data, filed accounts and software exports. Any outstanding balance with your previous provider is a matter between you and them; we keep the handover and that conversation separate.
Can I switch in the middle of a VAT quarter or part-way through a year?
Yes. Mid-period moves are ordinary work. It takes a little longer to establish opening balances, because we reconcile rather than assume what we are given. We agree in writing who completes the return covering the changeover, so there is no ambiguity about responsibility for that period.
Is the handover charged for, and how does the ongoing fee work?
The handover from your current accountant or bookkeeper is managed by Ardein at no separate charge. The ongoing arrangement is a monthly fee scoped to the work, agreed after we have seen the records and understood how the business runs, rather than quoted blind from a turnover figure.
How soon will I get monthly numbers after the move?
The defined ninety-day onboarding sets the pace. Month one is clean foundations, month two is the routine and controls, and by month three the finance function runs to an agreed timetable with monthly management information on cash, debtors, creditors and performance, delivered on the same date each month provided the information is with us.
Where we stand
When you are switching accountants, the disruption you fear is mostly the administration, and the administration is the part that can be handed over. Clearance, records, authorisations and the responsibility map are our work, not yours.
What you are left with is the useful part: deciding what you want from a finance function, and answering questions about how your business actually runs.
Capacity here is capped at four new clients a month, so a move is planned around your year end rather than squeezed in. If your numbers arrive too late to be useful and you have been putting off the change for a year, that is the conversation worth having.
