Not all South London accountants are built to advise businesses with high accounts receivable exposure. Construction firms dealing with CIS retentions, hospitality businesses managing supplier credit terms, legal practices billing on WIP, and creative agencies chasing milestone invoices all need an accountant who understands the sector-specific dynamics of late payment — not just year-end compliance.
In 2025, 62.6% of UK SME invoices were paid late. For construction businesses the figure is higher. For hospitality it is higher still. The accountant you choose should be able to advise on:
| Dimension | Weight | What We Measured |
|---|---|---|
| Digital Adoption | 30% | Cloud platform certifications (Xero Gold/Silver, QuickBooks), online client portal, app advisory services |
| Service Breadth | 30% | Compliance depth (accounts, tax, VAT, payroll), advisory range, specialist services |
| AR Sector Coverage | 40% | High-AR-risk sectors served (construction, legal, hospitality, contractors, creative), cash flow advisory, contractor/CIS experience |
Composite = Digital (30%) + Service Breadth (30%) + AR Sector Coverage (40%). Scored on public evidence only — no firms were contacted or paid for inclusion.

The accountants ranked highest for AR sector coverage — THP, LOYALS, One Abacus — are advising clients in sectors where late payment is structurally embedded. Accountant advice on payment terms and cash flow management is necessary but not sufficient. Automating the collection process is what moves debtor days.
