WRITTENOctober 2026 READING · Ten minutes FOR · CFOs, finance directors, financial controllers RELATES TO[Embedded AI delivery](https://anywayventures.com/embedded-ai-delivery) AI for finance teams is worth doing, but mostly not where the conference slides point. In a UK mid-market or PE-backed business, the time it genuinely saves sits in the high-volume, rules-heavy work: supplier invoice capture and coding, reconciliations, credit control and the first draft of month-end commentary. The judgement calls, the approvals and the numbers you sign stay with people, and the design should make that obvious to your auditors. What follows is a vendor-neutral, ranked list for a finance function running on Xero, Sage, NetSuite or Dynamics, with a rough sense of what each use case costs you today and returns once it's working. The best finance use cases move a person from doing the work to reviewing it, and leave the approval exactly where it was. > The best finance use cases move a person from doing the work to reviewing it, and leave the approval exactly where it was. ## Where AI for finance teams actually saves time Finance is further along than most functions. Gartner's 2025 AI in Finance survey of 183 CFOs and senior finance leaders, [reported by CPA Practice Advisor](https://www.cpapracticeadvisor.com/2025/11/18/gartner-survey-shows-finance-ai-adoption-remains-steady-in-2025/173371/) , found 59% said their finance function uses AI, almost unchanged from 58% the year before. Among those using it, the most common use was knowledge management (49%), followed by accounts payable automation (37%) and error and anomaly detection (34%). Across the wider UK economy the picture is thinner. The [ONS](https://www.ons.gov.uk/businessindustryandtrade/business/businessservices/articles/artificialintelligenceinukbusinesses/2023to2026) found self-reported AI use among businesses with ten or more employees rose from around 12% in late 2023 to around 35% by June 2026, but only around 10% of those adopters described their use as extensive. So most finance teams have a chat assistant and perhaps a capture feature switched on in the ERP. Very few have redesigned a process around it. That's the gap. The time in a finance function isn't spent writing emails. It's spent keying, matching, chasing and explaining. Those four verbs are where to look. ## AI use cases in finance, ranked Here is how I'd rank the common candidates for a finance team of eight to twenty people. Effort figures are illustrative, for a business around £30m to £150m revenue. Payback assumes a sensible build and honest measurement, not a vendor case study. Use case Typical effort today (illustrative) What AI does Human control point Buy or build Rough payback (illustrative) AP capture and coding 1 to 3 FTE keying and coding invoices Reads invoices, matches to PO and GRN, proposes nominal, cost centre and VAT code Approver signs off before posting; mismatches go to a queue Buy first: ERP capture feature or AP tool. Build only for awkward matching 3 to 9 months Supplier statement reconciliation 2 to 5 days a month for top suppliers Reads statements, matches to the ledger, explains each difference Clerk reviews the explained differences and decides the action Small build, unless your AP tool already does it 3 to 9 months Bank and intercompany reconciliations 1 to 4 days a month, more with many entities Suggests matches, clears the obvious, explains the rest Preparer and reviewer sign-off unchanged Buy for bank (native in most ERPs); build for intercompany 3 to 6 months Credit control and dunning 1 to 2 FTE chasing, matching remittances Prioritises the ledger, matches remittances, drafts tailored chases, triages disputes Controller approves sends to key accounts; no legal letters without review Buy a credit control tool; build dispute triage if volume justifies 2 to 6 months, mostly through cash Month-end variance commentary 2 to 4 days of analyst time per close Drafts first-cut commentary from the TB, budget and prior period Finance manager edits and owns every sentence Build, small, on your own data 6 to 12 months Board and lender pack 3 to 5 days per month or quarter Assembles the pack, drafts narrative, checks covenant calcs and cross-references FD reviews; covenant figures recomputed deterministically Build 6 to 12 months Expense review Hours a week checking claims against policy Flags out-of-policy claims, duplicates and missing receipts Manager or finance approves flagged items Buy: most expense tools now include it 3 to 9 months Two patterns stand out. The first four are high volume with a checkable answer, which is why they pay back fastest. And "buy" comes first wherever the job is common to every business. Xero, for example, now markets [AI document capture and automatic bank reconciliation](https://www.xero.com/uk/ai-in-accounting/) under its JAX brand and claims 97% reconciliation accuracy. Treat any vendor's accuracy figure as a claim to test on your own data, but check what your existing licence tier already includes before you pay anyone to build. ## AI for accounts payable and invoice processing AP is usually the first candidate and the easiest to evidence. AI invoice processing reads the invoice from the inbox, matches it to the purchase order and goods received note, proposes the coding and routes it for approval. Clean invoices take seconds to approve; mismatches arrive in a queue with the reason attached. I've written a full worked example with the payback maths, including a half-capture sensitivity case, in [how to measure AI ROI](https://anywayventures.com/insights/measuring-ai-roi) , so I won't repeat it here. The short version: a three-person AP team processing a few thousand invoices a month can plausibly get back more than half its hours, but only once supplier master data and coding rules are clean. Two things go wrong in AP more than anywhere else. The first is coding drift: the model learns from historical coding, and historical coding was inconsistent, so it confidently reproduces the inconsistency. Agree the coding rules before you train anything. The second is fraud. An invoice with changed bank details looks perfectly normal to an extraction model. Bank detail changes must always trigger an out-of-band verification, a phone call to a number you already hold, and the AI should flag them, never action them. ## AI credit control without annoying your best customers Credit control is where AI can move cash rather than just hours. The UK government's [Small Business Commissioner](https://www.smallbusinesscommissioner.gov.uk/new-powers-for-the-small-business-commissioner-as-part-of-government-package-to-tackle-late-payments/) says late payments cost the economy almost £11 billion a year and that business owners spend an average of 86 hours chasing debt. The March 2026 package confirmed a 60-day cap on payment terms for large firms paying smaller suppliers and mandatory interest on late payment. If you sell to large customers, that gives your credit controllers a firmer footing, and they should use it consistently. (If you are the large customer, your AP process now has a hard deadline to meet.) What AI credit control does well: Ranks the aged debt each morning by risk and value, not alphabetically. Matches remittance advices to open items, which is often the most tedious part of the job. Drafts chases that reference the actual invoices, the customer's payment history and any open query. Reads incoming replies and sorts them: promise to pay, dispute, remittance, out of office. What it shouldn't do is decide who gets a stop, a statutory interest claim or a legal letter. Those decisions affect customer relationships worth far more than the debt, and they belong with someone who knows the account. Keep sends to your top accounts behind an approval step, at least until you have months of evidence. ## AI month-end close, variance commentary and the board pack AI month-end close gets oversold. The close is a sequence of controls, and most of it should stay deterministic. Accruals, prepayments and journals are rules, and rules don't need a language model. Where AI helps is the reading and writing around the numbers. Variance commentary is the clearest case. An analyst spends two or three days each month pulling the trial balance against budget and prior period, finding the movements over threshold and writing an explanation for each. A small tool can produce the first draft in minutes: the movement, the transactions behind it, and a plain-English line drawn from invoice descriptions and journal narratives. The finance manager then edits it. The time saving is real, but the bigger gain is that the analyst spends the time on the three variances that matter instead of the thirty that don't. For the board and lender pack, the same idea applies. Let AI assemble, cross-reference and draft. Let deterministic code compute every number, especially covenant calculations. Never let a model do arithmetic that goes to a lender. ## The controls your auditors will ask about Auditors are already thinking hard about AI in their own work. The FRC published [guidance on the use of AI in audit](https://www.frc.org.uk/news-and-events/news/2025/06/frc-publishes-landmark-guidance-providing-clarity-to-audit-profession-on-the-uses-of-ai/) in June 2025, focused on proportionate documentation and explainability of AI tools. Expect the same lens to be turned on yours. The checklist I'd build in from day one: Segregation of duties. The AI can prepare; it cannot approve. Nothing it touches should let one actor both create and authorise a payment or a supplier. Human approval before anything irreversible. Posting, paying, sending to a customer, changing master data. Approvals sit with the same people and limits as your existing delegated authority. An audit trail from source to posting. Source document, extracted data, proposed coding, any edits, approver, timestamp. Stored, searchable and kept for your retention period. Change control on prompts and rules. Treat them like system configuration: versioned, reviewed and tested before release, with a record of who changed what. An evaluation set. A few hundred historical items with known correct answers, rerun after every change. This is your evidence that accuracy hasn't drifted. Least-privilege access. Read access to what it needs, write access to a held or draft status only. Data protection. Payroll and personal data stay out of general tools, and any AI processing personal data is covered in your UK GDPR records and supplier terms. A manual fallback. If the tool is down on day three of the close, the team can still close. None of this is exotic. It's the control environment you already run, applied to a new kind of preparer. ## Where not to use AI in finance There are places I'd keep AI well away from, however good the demo. Judgement areas. Provisions, impairments, revenue recognition on complex contracts, tax positions. AI can gather the evidence; it shouldn't form the view. Payment approval and bank detail changes. Ever. Final numbers without review. Anything that goes to the board, a lender, HMRC or the auditors is reviewed by a named person who signs it. Low-volume work. A task done ten times a month won't repay the build or the maintenance. Processes nobody has agreed. If three people code the same invoice three ways, fix that first. Automating disagreement just makes it faster. The wider version of this argument, including when a true agent beats a plain workflow, is in [AI agents for business operations](https://anywayventures.com/insights/ai-agents-for-business-operations) . ## A six-week sequence for a finance function This is the sequence I'd run for a first use case. It assumes one process, one owner in the finance team and a month-end inside the window. Week one: baseline and choose. Time the work on two or three candidate processes: volume, minutes per item, rework rate, who does it. Pick the one with the best mix of volume, clean data and low risk. Usually that's AP or a reconciliation. Week two: switch on what you already pay for. Check your ERP and AP tools for capture, matching and reconciliation features you haven't enabled. Clean the supplier master and agree the coding rules. Weeks three and four: build or configure with the controls in. Design the approval step, the exception queue and the audit log first, then the automation. Build an evaluation set from the last three months of real items. Week five: parallel run through month-end. Run the new process alongside the old one and compare outputs line by line. Fix the patterns in the exceptions. Week six: go live and report. Switch over with the fallback documented. Report hours returned against the baseline and pick the next process. Costs vary widely with what you buy versus build. I've set out the full cost of ownership, including running costs and a worked token example, in [how much it costs to build an AI agent](https://anywayventures.com/insights/how-much-does-it-cost-to-build-an-ai-agent) . One more thing worth planning for. Not every finance tool needs a project. A good management accountant can now build a variance summariser or a remittance matcher in an afternoon, given the right grounding and guardrails. That's why I'd pair the first build with some [hands-on AI training](https://anywayventures.com/ai-training) for the team, so the small tools get built in-house and the external spend goes on the processes that genuinely need it. The short version for a CFO: start where volume and checkable answers meet, in AP, reconciliations, credit control. Buy the common features before building anything. Keep approvals, judgement and signed numbers with people, and design the controls before the automation. Measure the baseline, run in parallel through a close, and report hours returned. If you want help taking the first finance process from baseline to live, with the controls your auditors will expect, that's the work we do in an [embedded AI delivery](https://anywayventures.com/embedded-ai-delivery) engagement. ## Questions ### What are the best AI use cases in finance? For a mid-market finance team, the ones that pay back fastest are accounts payable capture and coding, bank and intercompany reconciliations, supplier statement reconciliation and credit control. They share high volume, structured outcomes and a clear point where a person can check the result. Month-end variance commentary and board pack drafting come next. Judgement areas such as provisions and revenue recognition should stay with people. ### Can AI process supplier invoices in Xero, Sage or NetSuite? Yes. Most mainstream finance platforms now include some form of AI document capture, and dedicated AP tools add purchase order matching and approval workflows on top. Start with what your ERP tier already includes, measure the straight-through rate on your own invoices, and only build something custom for the awkward part, usually complex matching or coding rules the standard feature cannot learn. ### Will auditors accept AI in the finance process? They will if the controls are designed properly. Expect questions about segregation of duties, who approves what, the audit trail from source document to posting, how changes to prompts and rules are controlled, and how you test accuracy. Keep a human approval before anything is posted or paid, log every action with the approver, and keep an evaluation set you rerun after every change. ### How long does it take to implement AI in a finance team? A first use case can be live in about six weeks: one week to baseline and choose, one to switch on existing ERP features and clean master data, two to build or configure with controls, one parallel run through a month-end, and a go-live week. Wider rollout across the function then takes a few months, one process at a time, measured against the baseline. Brannan Coady Founder of Anyway Ventures.
