UK small business accounting practices face a fundamental choice when capacity is stretched: refer clients to large firms like Grant Thornton (losing the relationship forever), or partner with white-label accounting services providers like Acenteus (keeping clients while expanding capacity invisibly). This isn't a comparison between similar accounting outsourcing services—it's a strategic decision between protecting your practice or strengthening your competition. Grant Thornton serves businesses directly as your competitor; Acenteus delivers white-label accounting services to practices as your invisible partner.
Acenteus: White-label accounting services provider helping practices expand capacity while retaining 100% client ownership
Grant Thornton: Full-service accounting firm with 5,000 UK employees, 200+ partners, and 23 offices—competing for the same small business clients your practice serves
The fundamental difference: Acenteus white-label accounting services help you keep and grow clients; Grant Thornton takes clients from small practices.
| Factor | Acenteus (White-Label Partner) | Grant Thornton (Your Competitor) |
|---|---|---|
| Who they serve | Accounting practices (B2B white-label) | Businesses directly (B2C) |
| Your client relationship | You retain 100% client ownership | Client becomes Grant Thornton client |
| Brand visibility | 100% white-label; invisible to clients | Grant Thornton brand replaces yours |
| Service positioning | Extends YOUR capacity | Replaces YOUR firm |
| Pricing model | Transparent per-service costs | Enterprise pricing (undisclosed) |
| Market position | Partner enabling small practices | Competitor targeting your clients |
| Business model | B2B white-label accounting services | B2C (your clients become their clients) |
| Long-term strategy | Help practices grow and retain clients | Grow by acquiring small practice clients |
When capacity is stretched, referring clients to Grant Thornton seems practical. But consider what you’re actually losing:
Immediate Loss:
Long-Term Damage:
Financial Impact of Losing One £5,000/year Client to Grant Thornton:
If you refer 3 clients annually over 20 years = 60 lost clients = £1.8M-2.1M lifetime opportunity cost
Using Acenteus white-label accounting services, you:
Retain Everything:
Expand Capacity:
Strategic Growth:
Financial Impact Using White-Label Accounting Services Instead of Referring:
Understanding when white-label accounting services partnership pays off:
Setup secure file transfer and cloud platform access
Process first 5-10 pilot files through Acenteus white-label accounting services
Your team verifies quality with comprehensive documentation
Investment: Your time (2-3 hours setup + 1-2 hours weekly review)
Quality verified through “minimal errors” delivery
First client work processed with 30-40% less review time
First margin realized: Client fee £5,000, Acenteus cost £1,500 = £3,500 margin
Benefit: First £3,500 margin achieved; quality confidence established
Six months of white-label accounting services processed
First client annual work completed (bookkeeping, VAT, payroll, accounts, tax)
Annual margin per client: £3,000-3,500 profit
Benefit: Annual value proposition proven; expand to more clients
One full year using white-label accounting services
Typical practice: Keep 3 clients that would have been referred = £15,000 margin
Annual savings achieved vs cost of referring (£15,000 earned vs £0 if referred)
Breakeven achieved; pure profit begins
Year 2: Keep 3 additional clients (total 6 retained) = £30,000 annual margin
Year 3: Keep 3 more clients (total 9 retained) = £45,000 annual margin
Year 5: Total 15 clients retained through white-label accounting services = £52,500 annual margin
5-year cumulative advantage: £165,000+ vs. £0 if clients referred to Grant Thornton
For practice referring 3 clients annually to Grant Thornton:
Using white-label accounting services instead: Keep all clients = £165,000+ five-year value
Referring to Grant Thornton: Lose all clients = £0 revenue, £90,000-105,000 opportunity cost
Total advantage: £255,000-270,000 over five years
