Xenon Connect compares the year-end balance sheet in the bookkeeping software (such as Xero, QuickBooks Online, FreeAgent, or Sage) with the balance sheet filed at Companies House, ensuring the figures align.
In particular, it verifies that the Net Assets value matches—highlighting discrepancies that could otherwise go unnoticed until much later.
Once statutory accounts are filed, the numbers are assumed to be final—but bookkeeping files are often adjusted after year end, or may never have been fully aligned in the first place.
Even small mismatches between the bookkeeping balance sheet and filed accounts can create issues, including:
Confusion during future reviews or client handovers
Errors rolling forward into the next financial year
Risk during compliance checks or due diligence
Time-consuming investigations months or years later
The Xenon Connect and Companies House integration helps firms catch these issues automatically, giving confidence that what’s in the books matches what was filed.
