Challenge

An accounting and advisory firm processed supplier invoices and receipts for a large portfolio of small business clients.

Documents arrived in every format imaginable, and junior staff spent much of their time typing them into accounting software:

Manual data entry from PDFs, photos and scanned invoices.
Inconsistent coding to the chart of accounts across clients.
Duplicate and incorrect invoices slipping through.
Month-end crunch and overtime.

The firm wanted to take on more clients without growing the bookkeeping team at the same rate.

Solution

Winklix delivered an AI document agent connected to the firm's intake mailbox and its clients' accounting systems.

Intelligent extraction

Invoices and receipts are read with Azure Document Intelligence and a language model to capture supplier, dates, line items and tax with high accuracy.

Validation & coding

Each document is checked for duplicates and anomalies, then coded to the right accounts using the client's history and rules.

Accounting integration

Approved bills are posted to Xero or QuickBooks with the source document attached.

Exception review

A review screen shows only low-confidence or unusual items, so accountants spend their time on judgement, not typing.

Accounting & Advisory Firm solution delivered by Winklix

The Approach

Workflow first — We mapped the real workflow with the people doing the work before choosing models or tools.
Human in the loop — Every AI output had a clear review point, confidence thresholds and an escalation path to a person.
Prototype, then scale — A working pilot on real data proved the value before the solution was rolled out more widely.
Measured from day one — Baseline metrics were captured up front so improvements could be tracked objectively.

Outcome

The engagement delivered clear, practical results for the client:

Around 85% of invoices processed with no manual data entry.
Bookkeeping time per client reduced by roughly 60%.
Fewer duplicate and miscoded invoices.
Capacity to onboard new clients without adding headcount.
