The Client
The Challenges
Our client is a small, VAT-registered limited company with two directors and four employees.
As the business grew, one of the directors gradually took on responsibility for payroll and bookkeeping alongside running the business day-to-day — despite having no formal training in either area.
What started as a practical solution became increasingly difficult to manage, with financial admin being fitted around an already demanding workload rather than handled in a structured way.
As the business grew, the lack of structure began to cause real issues.
Suppliers were often paid late due to missing statements, while customers paid late because invoices were only raised monthly on 30-day terms, meaning cash regularly took up to 60 days to arrive.
At the same time, compliance was slipping:
- VAT returns were frequently late and unchecked
- Confirmation Statements were only filed after strike-off warnings
- Annual accounts were delayed or incomplete
Payroll was also becoming a risk area, with missing P60s, incorrect PAYE payments, and unclaimed Employer’s National Insurance.
The situation was further complicated by the accountant being a friend – leading to blurred responsibilities and limited accountability.
How Mercury Helped
We began by rebuilding the financial foundations properly, focusing on accuracy, structure, and visibility from day one.
The business was migrated from QuickBooks to Xero, historic errors were cleaned up, and the Chart of Accounts was redesigned so the numbers finally made sense.
This ensured that financial data was no longer just being recorded, but could actually be relied upon to understand performance, cash flow, and tax position.
Alongside this, we introduced consistent processes and hands-on support to bring structure to the day-to-day running of the finances, removing the pressure from the directors and restoring confidence in the numbers.
- Weekly bookkeeping taken over
- Invoice processes improved to support faster cash flow
- Bank accounts fully reconciled
- Full VAT review carried out
- Confirmation Statement brought up to date
- Weekly payroll taken over
- Outstanding accounts filed
- VAT errors identified and corrected
£21,000 corporation tax rebate identified and recovered
Regular check-ins introduced from day one
The Outcome
VAT submitted accurately and on time
Clear, reliable management accounts
Improved cash flow through better invoicing
Reduced late payments with regular customer statements
With the right systems, processes, and ongoing support in place, the business quickly regained control across its finances – moving from reactive and uncertain to structured, accurate, and reliable.
This gave the directors the confidence to plan ahead and make informed decisions, including whether the business could take on new staff.
What had previously felt overwhelming became structured, compliant, and manageable, with finances now supporting the business, rather than holding it back.
When both directors later faced serious health challenges, the systems and support already in place meant the business could continue running smoothly.
We stepped in to provide additional support, working directly with the team and increasing communication to ensure everything stayed on track during a difficult period.
Final Thoughts
This is a situation we are seeing more frequently, particularly where accounting support has evolved informally rather than strategically.
For growing SMEs and limited companies, small improvements to systems, processes, and support can make a significant difference.
Good financial support should reduce pressure, improve clarity, and help business owners make confident decisions. It should never add stress.
