Start with the legal structure
A limited company is legally separate from its owners, so its banking and accounting records must be separate. A sole trader is not a separate legal person, but still needs complete records to calculate taxable business profit. Identify the structure, start date, accounting period and registrations before choosing a process.
Separate the money and control access
Open an appropriate business account, route income and costs through it and avoid treating the balance as personal spending money. Give each user their own access, use stronger approval for payments and remove access promptly when roles change.
Record money introduced by or paid to founders in the correct account rather than guessing later.
Capture evidence as work happens
Keep sales invoices, supplier bills, receipts, contracts, bank statements, payroll records and explanations for unusual transactions. The bookkeeping entry and source document should agree. Missing evidence turns routine year-end questions into slow investigations.
Build a dependable system
Choose software that supports bank feeds, reconciliation, secure permissions, exports and the tax or VAT features relevant to the business. Automate capture where it removes repetition, but keep human review for duplicates, personal costs, VAT treatment and unusual items.
Use a weekly and monthly rhythm
Each week, issue invoices, capture costs and review overdue debts. Each month, reconcile every bank and card account, review debtors and creditors, investigate unexpected balances and update the cash forecast.
Plan the first year before deadlines arrive
Put Companies House, HMRC, payroll, VAT and pension obligations in one compliance calendar. First company accounts can cover a different period from the first Corporation Tax return, so do not infer one date from another.
Know what remains the founder's responsibility
An accountant can prepare records, returns and advice, but directors remain responsible for company records and filings. Agree who does what, when information is due and who approves submissions.
Founder checklist
- Confirm the structure and registrations

Frequently asked questions
Can I use my personal bank account?
A limited company's finances must be clearly separate; an appropriate business account is the simplest control. Sole traders should also separate activity, subject to their bank's terms.
Do I still need records if I hire an accountant?
Yes. An adviser can help, but the business must provide complete information and directors retain legal responsibilities.
What should I keep?
Keep records of income, spending, assets and liabilities, plus the documents needed to explain and support those entries.
How long should records be retained?
Rules differ and exceptions can extend them. Confirm the current GOV.UK requirement before setting a deletion policy.
