Your sales pipeline is healthy. The team is growing. A board meeting or funding conversation is coming up. Then someone asks a simple question: ” What was our gross margin by product last quarter?, and the answer is “Give us a week.”

That pause is normally not a people problem. More often than not, it’s a sign the finance system that served you well at £1m turnover is creaking at £5m, and will break entirely at £10m.

For leadership teams in Exeter, Bristol, London, and across the South West tech ecosystem, the finance function is often the last part of the business to get an upgrade. Product gets investment. Sales gets a CRM. Finance gets another spreadsheet tab…

Here are six warning signs your finance system is no longer fit for purpose, and what to do about each one.

What it looks like:

Management accounts land in the third or fourth week of the following month. By the time you see October’s numbers, you’re halfway through November, and the decisions they should have informed have already been made.

Why it matters:

Late numbers are backward-looking numbers. You end up running the business on instinct and bank balance, which works until it doesn’t. Slow closes also tend to signal deeper issues: manual journals, unreconciled accounts and last-minute corrections.

How to fix it:

• Move to daily or weekly bank reconciliation using bank feeds and rules in your accounting platform, rather than a month-end scramble
• Build a documented close checklist with owners and deadlines for each task
• Automate recurring journals, accruals and prepayments wherever possible
• Agree a target close date and measure against it every month

What good looks like:

Management accounts within 5–10 working days of month-end, with a short commentary explaining variances, not just a P&L export.

What it looks like:

Revenue lives in one workbook, the forecast in another, and the “real” customer list in someone’s personal OneDrive. Version control means emailing Forecast_v14_FINAL_edits.xlsx. Nobody is quite sure which number is right.

Why it matters:

Spreadsheets are brilliant analysis tools and poor systems of record. Formula errors, broken links and copy-paste mistakes creep in silently. When an investor, auditor or acquirer asks for a reconciliation, the gaps become very visible, very quickly.

How to fix it:

• Make your accounting platform (for example, Xero) the single source of truth for transactional data
• Keep spreadsheets for modelling and scenario analysis, fed from the ledger rather than replacing it
• Introduce reporting tools that pull live from your ledger, so dashboards update without manual rekeying
• Lock down and document any spreadsheets that genuinely need to remain business-critical

What good looks like:

One agreed number for revenue, cash and margin, traceable back to source transactions, whoever runs the report.

What it looks like:

Sales data sits in the CRM, invoices are raised in a separate billing tool, payroll runs on its own platform, and expenses arrive as photos on WhatsApp. Someone on the team spends days each month rekeying data between them.

Why it matters:

Every manual handoff is a chance for error and a drain on time. For subscription businesses, it’s worse: if billing and the ledger disagree, your MRR, ARR and deferred revenue figures can’t be trusted — and neither can any metric built on them, from churn to NRR.

How to fix it:

• Map your current finance stack end to end: where data starts, where it’s rekeyed, and where it ends up
• Prioritise integrations at the highest-volume handoffs first, typically CRM → billing → ledger
• Use purpose-built apps that integrate natively with your accounting platform for expenses, receipts, payroll and subscription billing
• Retire tools that duplicate each other rather than adding another layer

What good looks like:

Data entered once, at source, flowing automatically into the ledger and reporting, with exceptions flagged for review rather than every transaction handled by hand.

What it looks like:

You know your bank balance today, but you’re less confident about where it will be in 13 weeks. Hiring decisions, marketing spend and pricing changes are made without modelling their cash impact. Cash surprises — a big VAT bill, a delayed customer payment — catch you off guard.

Why it matters:

Growth consumes cash. Faster-growing businesses often feel the squeeze most, because they invest in people and acquisition before the revenue arrives. Without forward visibility of burn rate and runway, you’re either too cautious and miss opportunities, or too aggressive and run short.

How to fix it:

• Build a rolling 13-week cash flow forecast, updated weekly
• Maintain a 12–24 month driver-based forecast linking headcount, pipeline and pricing to P&L and cash
• Model scenarios — base, upside, downside — before committing to major hires or spend
• Set clear cash triggers: what you’ll do if runway falls below an agreed number of months

What good looks like:

You can answer “can we afford this hire?” in an afternoon, with the cash impact modelled, rather than a gut feel.

Worked example

Consider a Bristol-based B2B software business at £3m ARR, planning to hire four engineers (on £60,000 salaries) and two salespeople (on £50,000) over the next two quarters. On a P&L view, monthly salary costs of around £30,000 look comfortably affordable.

But the true cost of each hire lands well before the first payslip:

• Recruitment fees, typically around 20% of first-year salary, are paid on placement: £48,000 for the engineers and £20,000 for the salespeople, a total of £68,000
• Capital expenditure on laptops, monitors, software licences and equipment adds roughly £2,000 per head, so £12,000
• Additional desk space, whether extra co-working memberships or a larger office footprint, often means deposits or advance payments, say £6,000.

That’s around £86,000 of cash out of the door before the new team has delivered anything.

Then there’s the productivity lag. New employees typically take around three months to reach full effectiveness, and in sales it’s often longer: pipeline has to be built, deals take time to close, and cash from those deals arrives later still. So the business carries a full salary cost for a quarter or more while revenue from the new hires is close to zero.

Layer on the timing of existing cash flows (annual contracts renewing mainly in Q1, a VAT quarter falling in the same month the hires start, and two large customers that routinely pay at 60 days), and the result is a cash pinch in months two to four that the P&L never showed.

Phasing the sales hires by eight weeks, negotiating staged recruitment fees, and tightening credit control resolves it. But only because the 13-week cash forecast surfaced the problem in time.

Figures are illustrative.

What it looks like:

You can report revenue and profit, but struggle with the questions investors, lenders and your own board actually ask. What’s your customer acquisition cost? Your LTV: CAC ratio? Gross margin by product line or customer cohort? Revenue recognised versus billed?

Why it matters:

Statutory-style accounts tell you what happened. Decision-ready management information tells you why, and what to do next. If you can’t evidence unit economics, you’ll find fundraising, refinancing or a sale harder, slower and potentially on worse terms. For subscription businesses, revenue recognition under IFRS 15 also needs to be handled correctly, not approximated.

How to fix it:

• Agree a core KPI set with your leadership team — typically no more than 10–12 metrics that genuinely drive decisions
• Structure your chart of accounts and tracking categories so those metrics can be reported directly, without manual allocation
• Produce a monthly management pack combining financials, KPIs and commentary
• Benchmark your metrics against relevant peers, such as the Rule of 40 for SaaS businesses

What good looks like:

A board pack that lands on time, answers the obvious questions before they’re asked, and stands up to investor due diligence.

What it looks like:

One long-serving bookkeeper or finance manager knows how everything works. Processes aren’t documented. When they’re on holiday, invoices don’t go out, and suppliers don’t get paid. Approvals happen informally, if at all.

Why it matters:

Key-person dependency is both an operational risk and a control risk. It creates bottlenecks as transaction volumes grow, increases the chance of errors or fraud going unnoticed, and is a red flag in any due diligence process. It also limits the strategic support your finance function can offer: if your finance lead is buried in processing, nobody is thinking about margin, pricing or funding.

How to fix it:

• Document key processes: payroll, payment runs, invoicing, month-end close, VAT returns
• Introduce segregation of duties and approval workflows, particularly for payments
• Consider a blended model: outsourced bookkeeping and transactional finance, with fractional FD or CFO support for strategy and board-level reporting
• Review access permissions across your finance platforms regularly

What good looks like:

A finance function that keeps running smoothly when any one person is away, with strategic finance input available when the business needs it.

A slow close usually points to spreadsheet dependency; disconnected systems feed poor KPIs; key-person risk makes all of it harder to fix. That’s why piecemeal fixes — another app here, another spreadsheet there — often add complexity instead of removing it.

A more effective approach is to step back and design the finance function around where the business is heading, not where it’s been:

• Diagnose — review your current stack, processes, reporting and controls against the six signs above
• Prioritise — tackle the issues with the biggest impact on decision-making and cash first
• Rebuild — consolidate around a cloud accounting core, integrate the systems that matter, and automate repetitive work
• Upgrade the output — move from compliance-led accounts to forward-looking management information
• Resource it properly — combine the right mix of in-house, outsourced and fractional expertise for your stage of growth

Many growing businesses are well served by their accountant for year-end accounts and tax compliance. But building a finance function that supports scale, real-time reporting, cash forecasting, SaaS metrics, and investor-ready board packs is a different discipline.
