Scaling the finance function without a bigger finance team

Key takeaways

To scale the finance function in a small business, separate transaction processing from financial control. Invoicing, payment chasing, purchase ledger and reconciliations grow with volume and can run through a managed team. Approval, cash decisions and reporting to the owner stay inside, often with a part-time finance lead.

• Transactions scale with volume. Control does not.
• Outsource invoicing, chasing, purchase ledger and reconciliation.
• Keep payment approval and bank access with a named person inside.
• Statutory interest on late business debts is 8% above Bank of England base rate.

What breaks in finance as a business grows?

As a business grows, the number of invoices, payments and queries rises, and the one person who did the books at the weekend cannot keep up. Invoices go out late, debtors are not chased, and management figures arrive weeks after month end. Cash tightens even though sales are healthy.

Which finance work scales with volume?

The transactional layer scales with volume: raising sales invoices, matching payments, chasing overdue accounts, entering supplier bills, preparing payment runs and reconciling the bank. These tasks follow rules and can be measured by count, turnaround and error rate, which makes them suitable for a managed team.

• Sales invoicing and statements.
• Credit control and payment chasing.
• Supplier bill entry and matching.
• Bank and card reconciliation.
• Expense processing.

• Outsourced invoicing and credit control
• In-house vs outsourced bookkeeping: the cost compared

What must stay under your control?

Control must stay inside the business. A named person approves payments, holds bank authority, signs off write-offs and reviews the monthly numbers. Separate the person who prepares a payment from the person who approves it. That separation of duties matters more, not less, when part of the work is outsourced.

How does chasing payments affect growth?

Chasing payments is growth finance for a small firm. Cash collected a fortnight sooner funds stock, wages and marketing without borrowing. UK law allows businesses to charge statutory interest of 8% above the Bank of England base rate on late commercial payments, but polite, consistent chasing from the day an invoice falls due is more effective.

What does scaling finance this way cost?

Managed finance administration is usually priced per hour or per transaction. Indicative market ranges for managed back-office teams are £9–£18 per hour offshore and £20–£35 per hour onshore. Regulated work, such as statutory accounts and tax advice, remains with your accountant and is priced separately.

• BPO cost per hour in the UK
• Fractional teams: senior skills without a full-time salary

When should you build finance in-house?

Build finance in-house when the business needs daily commercial analysis, has complex stock or project accounting, or is preparing for investment or sale and wants a full-time finance director. Until then, a part-time finance lead with a managed processing team gives control without a department.

• When not to outsource

What does this look like in practice?

A pattern we see in UK firms of 10 to 30 people: invoices are raised in a batch at month end because nobody has time during the month, so customers pay a month later than they could. Moving invoicing to the day the job completes, and chasing on a fixed schedule, shortens the wait for cash without any change in sales.
