A change of accounting firm is not considered successful simply because the new service provider has received the files. It is successful when the data matches. Responsibilities are clearly defined. There is someone in charge of each open case. The first closing proceeds in a controlled manner.
This is a handover process.
Not a chain email. Not a data storage device. Not „we’ll make it up to you later.”.
1. Define the purpose of the change
Don't just write that you're choosing a new accountant.
Please note:
- why the change is taking place;
- which services will be transferred;
- what remains with other service providers or in-house;
- What is the planned deadline for delivery?;
- which month each person is responsible for processing;
- Who is the company's project manager;
- What constitutes a successful handover?.
A vague goal leads to vague accountability.
2. Make a complete to-do list
„Bookkeeping” is not a single task.
The job responsibilities may include:
- general ledger accounting;
- customer and supplier analytics;
- bank and credit union;
- tax returns;
- payroll processing;
- labor administration;
- property, plant, and equipment;
- stock;
- project or cost center accounting;
- Executive Summary;
- liaison with government agencies;
- year-end closing and reporting tasks;
- archiving.
For each row, assign the old, the new, and the company representative.
3. Data and Document Inventory
The handover is based on a data inventory.
Groups:
Company and Master Data
- company information;
- tax statuses;
- bank accounts;
- facilities;
- activities;
- contact persons;
- signing and approval rights.
Financial Data
- general ledger extracts;
- account summary;
- opening and closing balances;
- analyses;
- customer and supplier lists;
- tangible assets: cardboard boxes;
- accruals;
- Contingent and unspecified items.
Tax and Regulatory Documents
- tax returns;
- checking account information;
- decisions;
- audits in progress;
- permits and notifications;
- powers of attorney.
Wages and Labor Issues
- employee master data;
- contract details;
- vacation and absence;
- deductions;
- allowances;
- exit and entry matters;
- corrections currently in progress.
The data inventory should include the file name, time period, format, source, person in charge, and status.
4. Specify the closing limit
The most important question:
Until what date will the old accountant be working, and starting from what date will the new one take over?
Record the following separately:
- invoice processing;
- bank;
- payroll processing;
- tax return;
- summary;
- year-end closing;
- Adjustment for a prior period.
There should be no overlap without a designated person in charge.
There should be no gap between the two service providers.
5. Export Formats
Don't just ask for a PDF.
To retrieve data and import it into the new system, you may need:
- structured general ledger export;
- analytical lists;
- CSV or XLSX files;
- original receipt images;
- tax return and acknowledgment documents;
- system backups, provided they can be lawfully and technically transferred;
- methodological descriptions;
- to explain unique codes and dimensions.
It is not enough for the file to exist. The file must be openable, readable, and complete.
6. Recording of Open Items
All unresolved issues should be added to a central list.
Fields:
- item ID;
- period;
- problem;
- financial or tax implications;
- required document;
- current person in charge;
- new person in charge;
- deadline;
- status.
Examples:
- unmatched bank transaction;
- disputed sales invoice;
- missing supplier invoice;
- ongoing self-assessment;
- an unresolved employee matter;
- discrepancies between the general ledger and analytical balances;
- a matter pending with the authorities.
An open item does not disappear when you switch service providers.
7. Reconciliation Gateways
The handover shouldn't end with just a single „I've received it” message.
Minimal coordination:
- general ledger statements and analytical reports;
- bank closing balances;
- customer and supplier base;
- tax account and records;
- payroll data and obligations;
- property, plant, and equipment;
- outstanding advances;
- accruals;
- its relationship to the previous closed financial statements or year-end closing.
Each reconciliation must be assigned a status of "ACCEPTED," "ACCEPTED WITH COMMENTS," or "REJECTED.".
8. Access and Permissions Management
The transition is also an information security task.
Create an access log:
- accounting software;
- billing system;
- bank export interface;
- rental program;
- document repository;
- government interfaces;
- email addresses;
- cloud folders;
- reporting system.
Each access point should have:
- name;
- role;
- authorization level;
- activation date;
- date of revocation;
- Approving Officer.
Revoke the old access only after the handover and the necessary follow-up work have been completed in accordance with established procedures.
9. First Monthly Cross-Check
There should be increased monitoring during the first month of the new processing period.
Examine:
- completeness of invoices;
- bank pairing;
- tax and payroll obligations;
- general ledger logic;
- cost centers;
- open items;
- continuity of the executive summary;
- deadlines.
It is not necessary to maintain two complete sets of books at the same time.
However, targeted parallel checks are needed at critical points.
10. Acceptance Criteria
The transfer can only be completed if:
- the data inventory is complete;
- the files can be opened;
- the main balances match;
- The list of open items has been approved;
- the deadlines and responsibilities are clear;
- access is working;
- The first processing cycle has been completed;
- critical tax filing and payroll processes have been audited;
- The company's designated representative has approved the handover status.
Acceptance must be in writing.
11. 30-day stabilization period
The stabilization period begins after the handover.
Weekly Brief Review:
- a newly identified deficiency;
- data quality issue;
- process delay;
- barrier to access;
- client-side task;
- necessary correction;
- Person in charge and deadline.
After thirty days, prepare a final summary.
What has been transferred? What is still pending? Who is responsible for it? What is the final deadline?
12. What Not to Do
- Please do not send an unstructured collection of files.
- Don't leave the transition entirely up to the two accountants.
- Do not leave any time period without someone in charge.
- Don't switch accounting systems and accountants at the same time without a plan.
- Don't delete the old access too soon.
- Do not accept the transfer without prior consultation.
- Don't assume that the missing data will turn up on its own later.
Changing accountants isn't just about sending documents. It's a controlled transfer of responsibility.
Scope of Responsibilities. Data Inventory. Handover Deadline. Reconciliation. Acceptance.
The specific accounting, tax, data protection, and contractual measures must be tailored to the company’s situation and its requirements for expertise.
