Clearing the Invoice Backlog at a Mid-Size Accountancy Practice

Independent Accountancy Practice 14 staff — 300+ SMB clients Birmingham Challenge: Invoice processing & onboarding bottleneck

The Situation

A 14-person practice serving 300+ SMB clients was sitting on a 3-week invoice processing backlog. Two junior accountants were spending Monday mornings doing nothing but manually matching receipts to expense categories and chasing clients for missing documentation.

New client onboarding — KYC forms, engagement letters, practice management setup — was taking 5 business days and involved an average of 11 back-and-forth emails per new client.

Two senior partners estimated they were losing 20 billable hours a week to admin that “shouldn’t require a human.”

AI Opportunity Gap: HIGH

Assessment finding: The practice had reasonable tooling (cloud accounting, CRM) but almost no automation connecting them. The integration layer was entirely manual — a person copying data between systems.

What We Built

QuietBooks

Deployed for end-to-end invoice ingestion — OCR extraction from PDF and email attachments, automatic expense categorisation against client-specific rules, and exception flagging for human review. Junior accountants now only touch the edge cases QuietBooks can't resolve with confidence.

QuietGate

Deployed as the client onboarding intake agent — collecting KYC documentation via a structured conversation, validating completeness, triggering engagement letter generation via DocuSign, and pushing confirmed data directly into their practice management system. Average email thread reduced from 11 exchanges to 3.

Integrated with Xero, their existing CRM, and DocuSign. Zero change to client-facing tools — the AI worked entirely behind the scenes.

“The ROI conversation with our partners was straightforward once we saw the numbers. This pays for itself in month one on the senior partner time alone.”
