FAQ
What is the difference between bookkeeping software and accounting software for a small business?
Bookkeeping software focuses on recording daily transactions, reconciling bank feeds, issuing invoices, and capturing expense receipts. Full accounting software adds double-entry accrual journals, fixed-asset depreciation schedules, multi-entity consolidation, and statutory tax reporting.
How long must a UK small business keep digital accounting records?
Limited companies must retain accounting records for at least 6 years from the end of the financial year they relate to, while sole traders must keep records for at least 5 years after the 31 January Self Assessment submission deadline.
