Switching accountants without losing the history
Prepare an organised accountant handover with records, access, opening balances and clear responsibility for work around the switching date.
Changing accountants should improve the records, not leave you between two inboxes when a deadline arrives. The difficult part is often the handover rather than choosing the new person. You need the history, access to your own information and a written answer to who is doing which job. Prepare those pieces before you assume the switch is complete.
Choose a handover date and divide the work
Agree the date from which the incoming accountant takes responsibility for the work in their engagement. Then list every unfinished task around that date. Include monthly bookkeeping, payroll where relevant, outstanding returns, year-end work and replies to authority correspondence. A sentence saying the new accountant takes over everything can conceal different assumptions about work that began before the switch.
Ask both sides to confirm what they will finish, what they will transfer and what they need from you. Keep the list in writing. If a deadline is close, give that task a named owner now. Do not wait for every historical document before establishing who is handling an immediate obligation. The incoming adviser needs enough time and information to decide whether they can accept the task.
Ask for records that explain the balances
Request the accounting export, latest trial balance, detailed ledger, bank reconciliations and customer and supplier balance lists. Ask for supporting schedules for material balances such as loans, fixed assets and owner transactions. The exact pack depends on your business and the engagement. A set of annual statements is useful, but it may not explain all the entries the new accountant needs to continue the records.
Collect filed returns, submission confirmations, relevant payment evidence and correspondence with authorities. Keep a list of open enquiries and unresolved bookkeeping questions. If someone used an estimate or made an adjustment, ask for the explanation and supporting calculation. A number copied into a new system without its history can carry an old error into an otherwise clean set of records.
Put business access under business control
List the software, document storage, bank reporting tools and tax or payroll portals used for the work. Identify the account owner and the access each person has. Ask how professional permissions should be changed. Use the platform's proper authorisation process rather than sending personal passwords in an email. Your business should know where its records are and how an authorised person can retrieve them.
Export copies before closing subscriptions or removing access. Check that the files open and contain the expected periods. A download button does not guarantee a complete handover. If the outgoing accountant owns a software subscription, agree the export and continuity arrangements before it ends. Keep the explanation of what is included in the export so you do not assume attachments or audit history transferred when they did not.
Give the new accountant a short business briefing
Explain what you sell, where customers and suppliers are based, how payments arrive and who approves spending. List employees, payment processors, financing and unusual arrangements. Mention seasonal patterns and changes planned for the next few months. The new accountant should not have to infer the business model from a folder of invoices. A concise briefing saves time and helps them ask relevant questions.
Describe the reason for switching using specific examples. Perhaps monthly reports arrived late, questions remained unanswered or you could not understand extra fees. Distinguish documented errors from concerns that still need checking. Ask what process the new engagement will use to address those problems. A promise that things will be better is less useful than an agreed reporting date, response process and clear division of responsibility.
Check the opening position before relying on new reports
Ask the incoming accountant to explain how opening balances will be checked. Agree whether the scope includes reviewing historical errors or simply continuing from supplied figures. Those are different pieces of work and can have different fees. If there is a backlog, request a separate plan with the affected periods, evidence needed and assumptions. Do not let historical clean-up disappear inside a vague monthly service description.
For an illustrative example, a customer balance in the old records might include invoices already paid but never allocated. Importing that balance makes the new report look as though the customer still owes money. Matching the balance to invoices and receipts exposes the problem. The same principle applies to supplier balances and loans. Reliable continuity starts with explanations, not merely successful data import.
Test the handover with the first reporting cycle
At the first month end, check that the accounts include the right opening position, current transactions and known outstanding issues. Review the deadline list and confirm who has access to submission evidence. Ask for the query list and answer it promptly. A switch is a shared process, and the new accountant cannot resolve missing facts that only the business holds.
If you are considering ongoing bookkeeping support, use the handover checklist to compare scopes before agreeing an engagement. Ask what is included, what needs a separate review and what access you retain. Keep the final handover pack somewhere the business controls. It will be useful even if you stay with the next adviser for years.
