How can AI help an accountancy practice process supplier invoices?
A workflow can collect incoming invoices, extract supplier details, dates and amounts, flag missing or inconsistent information and prepare a draft ledger entry. The reviewer checks the source document, client, coding and tax treatment before posting. Existing capture tools may already provide much of this. The useful improvement depends on where your practice currently repeats work or spends time correcting it.
- An extracted total is not a decision about VAT treatment or deductibility.
- Duplicate detection needs to work across uploads and emails, not just within one batch.
- A draft awaiting approval and a posted ledger entry must remain clearly different states.
A supplier invoice arrives by email, another copy is uploaded to the portal and somebody enters the details into the ledger. The repeated work is receiving, identifying, checking and coding the document, not simply typing the total.
AI can assist with extracting and organising that information. Existing capture software may already cover much of the process, so the first question is where the practice still spends time correcting or re-entering it.
What happens between an invoice arriving and a draft entry?
A workflow can collect a document from an approved inbox or portal, identify the client and supplier, extract dates and amounts, then prepare a draft transaction. Each field should remain linked to the original invoice for review.
The system needs a route for uncertainty. If a scanned total is unclear or the document contains several tax rates, it should flag the issue rather than return a confident guess. A draft should remain a draft until an authorised reviewer approves it.
Which checks matter before posting?
The reviewer needs to confirm the client, supplier, invoice number, date, amounts and coding. Extracting “VAT £20” does not establish whether that VAT is recoverable or the treatment is appropriate.
Duplicate checks also matter. The same invoice may arrive by email and through an upload, with different file names. Comparing only the attachment name will miss that. A proposed workflow should explain how it recognises a possible duplicate and what happens when a supplier reuses an invoice number.
For example, an invoice for £120 containing £100 net and £20 VAT may be straightforward to read. If the document is actually a credit note, or belongs to another client, accurate extraction alone still produces the wrong ledger entry. The review needs the document context.
Understand AI, automation and agents, then choose a task to trial with clear rules and someone checking the result.
When are existing tools enough?
Review the capture and approval features already available in the practice's accounting and document tools. If they produce the required drafts and handle the exceptions adequately, another language-model integration may add little.
A separate workflow may be useful where documents need routing across systems, messages contain information outside the attachment or staff repeatedly prepare the same request for missing details. The supplier needs to confirm supported actions and account permissions before promising a connection.
How can client chasing avoid creating more work?
Use a current checklist for the relevant period and client. A reminder should name the missing document and stop when it is received or the team records why it is not required.
The practice needs to distinguish a document arriving from its review being complete. A client should not receive a message saying that a return is ready simply because the final attachment reached the inbox.
What needs to be agreed before a trial?
Set the tool's access, approved uses and reviewer responsibilities around the practice's confidentiality and data-handling arrangements. The ICAEW AI resources can inform that assessment, alongside the practice's own policies and professional responsibilities.
Measure the whole process on a defined group of documents: preparation time, corrections, duplicate warnings and approval time. A workflow that extracts fields quickly but creates more review work may not improve the task.
Reeve Consult can review that process with your team, assess the connections available and scope the missing work. There is no universal “fastest-paying” workflow for every practice; the case depends on the work your team actually repeats.
