AI agents for accounting firms: 10 real workflows, explained

1Daily invoices, matched against the PO tracker, ready to post to QuickBooks

This is the classic three-way match, and it's where an agent earns its keep fastest, because the inputs are messy and scattered. Every morning at 8:00, Arjun's agent:

1. Collects new invoices from accounts@, the payables WhatsApp number and the vendor portal, and reads each one, scans included: vendor, GSTIN, invoice number, line items, quantities, rates and tax.
2. Matches every line against procurement's PO tracker (Excel) and the warehouse's goods-received sheet (Google Sheets): right PO, right quantity delivered, agreed rate.
3. Checks the rules Arjun has taught it: a price more than 2% above the PO, a repeated invoice number or amount, a GSTIN that doesn't match the vendor master, an invoice dated before its PO.
4. Builds a review table and sends it to Arjun in Slack.

Arjun looks at six rows instead of thirty-seven. He approves the 31 clean ones in one go and the agent creates the bills in QuickBooks with the PDF attached, the right expense account, tax code and due date. For Nova Prints, it has already drafted an email quoting the PO rate and the 20 missing reams; Arjun just presses send.

2Bank reconciliation when one deposit hides 214 orders

Matching one bank line to one invoice is easy. Reconciliation gets hard when a single deposit is the net of hundreds of transactions spread across three systems. Meera's agent pulls the bank statement, the Razorpay (or Stripe) settlement report and the Shopify order export, then breaks every payout into its parts and ties each order to its invoice in the books.

The fee and GST-on-fee entries come pre-drafted, so the input credit on gateway fees isn't missed. In the first week Meera corrects the agent a dozen times; by week four, 412 of 430 bank lines match themselves, and the 18 left over each come with a reason, such as "UPI receipt with no matching invoice" or "bank charge, needs a GL code".

3GSTR-2B vs Tally vs the vendor's ledger: protecting input tax credit

GST reconciliation is three-way too: what the vendor uploaded (GSTR-2B), what's in your purchase register in Tally Prime, and what the vendor's own statement says. The agent downloads GSTR-2B, exports the purchase register from Tally, compares them invoice by invoice and works out the credit at risk for each vendor.

Over a few months the agent also learns which vendors habitually file late, and suggests holding their payments until the return shows up: the cheapest way to protect credit. Once the vendors reply, it drafts the GSTR-3B summary for Ravi.

For UAE clients the same comparison runs for VAT: input tax in the books against suppliers' tax invoices and the return.

4A new client's messy Excel books, moved into QuickBooks or Xero

Onboarding is where firms lose the most unbilled time. Zoya's agent reads the client's Excel books and maps every account name to the firm's standard chart of accounts, then checks that the opening balances actually tie. Where it isn't sure, it says so instead of guessing.

Zoya answers the 14 questions, many of them by forwarding the agent's own list to the client, and approves the import. The agent creates the accounts, opening balances, customers, vendors and open invoices in QuickBooks or Xero, and attaches the source files. Next time it maps "Petrol & car" without asking, because the firm brain remembers.

5Expense claims checked against policy and the corporate card feed

Here the agent combines three sources nobody enjoys reconciling: the claims, the card transactions, and the client's travel policy, which it reads straight from the PDF. Then it checks every claim the way a careful auditor would.

Meera sends the flagged claims back to the client's finance head with the reasons attached; the 131 clean ones go straight into the reimbursement run. Nobody had to open 140 receipts.

6Collections that remember each client, and a 13-week cash forecast that updates itself

Sara's agent reads the receivables aging in QuickBooks and two years of payment history, and learns each customer's pattern. It drafts the right nudge in the right channel and tone, and predicts when each invoice will actually arrive, which matters more than when it's due.

Then it goes a step further. It takes those expected dates, adds Arjun's agent's payment schedule, payroll, rent and tax due dates, and builds a 13-week cash forecast that updates every morning.

7Month-end close: accruals, prepaids and variance explanations written from the emails

Meera's agent works through the close checklist. It accrues bills that haven't arrived yet (the cloud invoice always lands on the 5th, so it estimates from usage emails and the last three months), amortises prepaid insurance from the policy schedule, and drafts every journal for review. Then it does the part people dread: for every account that moved more than 10%, it finds the reason in emails, Slack and contracts, and cites the source.

The hard version: intercompany across three countries

One client has entities in India, the UAE and the US. Every month the intercompany balances refuse to agree, in rupees, dirhams and dollars. The agent pulls all three ledgers, converts at the right rates, and separates the difference into its causes: a payment still in transit, an invoice booked in different months, and pure FX. Then it drafts the elimination entries for consolidation.

8Tax season: 26AS and AIS matched to the books, and notices answered with evidence

Before filing, Ravi's agent downloads Form 26AS and the AIS for each client and matches them to the books: TDS a customer deducted but never deposited, interest income the bank reported that isn't booked, a property sale in the AIS that the client forgot to mention. For individual clients, it keeps a document checklist and chases the missing pieces (Form 16, capital gains statements, investment proofs) in each client's own channel.

When a notice does arrive, the agent reads it, works out exactly which figures are being compared, pulls the returns and ledgers for that period, and builds the reconciliation.

Ravi reads the draft, changes two sentences and submits it himself. Agents prepare tax work; they never sign or file it.

9Audit prep: the PBC list filled in before the auditors ask twice

The auditors send an 85-line "prepared by client" list in Excel. Ravi's agent works down it: ledgers and reports from QuickBooks or Tally, contracts and board minutes from Drive, bank confirmations from the inbox. It files each item in an indexed folder named exactly as the auditors asked, and writes first answers to their queries with references to the documents.

10When someone leaves, the firm keeps what they knew

When Arjun moves on, his agent's work memory moves to Zoya's agent: his vendors and their quirks, which ones file GST late, the approval rules, open bills and the half-finished Nova Prints query. His personal notes stay private. On her first day in payables, Zoya's agent already knows that Brightline bills go to 6300 and that Sharma Electricals' GSTIN is mistyped on their template.
