"AI saves time" is easy to say. It's harder to quantify. This article is an honest, task-by-task breakdown of the time required for bank reconciliation and BAS preparation under two approaches: traditional manual workflow and AI-assisted workflow using Reconlink.
The comparison uses a realistic benchmark client: a small Australian services business, one bank account, approximately 200 transactions per quarter, quarterly BAS lodgement, no payroll complications.
The baseline client
Client profile: Small services company. One trading bank account (major bank). Approximately 60–70 transactions per month. No employees, so no payroll reconciliation. GST-registered, lodges a quarterly BAS.
Quarter used: January–March (Q3 for most Australian businesses). 67 working days, 198 transactions.
Transaction mix (typical):
- Recurring vendors (software subscriptions, telco, utilities): 22% (44 transactions)
- Known irregular vendors (suppliers, professional services): 38% (75 transactions)
- First-time or ambiguous vendors: 18% (36 transactions)
- Client payments received: 22% (43 transactions — income coding)
Manual workflow: task breakdown
Step 1: Obtain bank statements (25 minutes)
The client downloads three months of CSV statements from their online banking. The bookkeeper receives them by email, saves to the client folder, and uploads them to the accounting software. Some months require chasing the client for the statement.
Time: 20–30 minutes, averaged across months that arrive on time and those that require chasing.
Step 2: Import and de-duplicate (15 minutes)
Import the three CSV files. Identify and remove any duplicate imports (a common issue when months have overlap or the client downloads statements more than once). Confirm the opening and closing balance against the bank statement.
Time: 10–20 minutes.
Step 3: Code 198 transactions (6–8 hours)
This is the main work. Each transaction requires:
- Reading the bank description
- Identifying the vendor
- Assigning the account code
- Assigning the GST code
- Verifying against the prior quarter for consistency
At an average of 2 minutes per transaction (some take 30 seconds, some take 5 minutes for ambiguous vendors requiring research), 198 transactions takes approximately 6 hours 36 minutes.
Time: 6–8 hours (centre of range: 7 hours).
Step 4: Query the client on unexplained transactions (45 minutes)
A typical quarter has 8–15 transactions the bookkeeper can't code without more information — ATM withdrawals, transfers to unknown accounts, unusual vendors. These require an email to the client, waiting for a response, and following up.
Time for composing and managing queries: 25–35 minutes. Client response time: 24–72 hours (not counted in bookkeeper time, but adds to elapsed calendar time).
Step 5: BAS calculation and review (45 minutes)
Once transactions are coded, calculate the BAS totals. Run a sanity check against the prior quarter — is G1 (total sales) plausible? Is the ITC rate consistent? Check for any miscoded transactions that distort the ratios.
Time: 40–50 minutes.
Step 6: BAS draft to client (20 minutes)
Prepare the BAS summary, send to client for approval, follow up if needed.
Time: 15–25 minutes.
Total manual workflow: approximately 9 hours per quarter per client.
At $120/hour, that's $1,080 in labour cost per client per quarter. For a 10-client practice, that's $43,200/year in labour costs for BAS preparation alone — before administration, client communication overhead, and practice management.
AI-assisted workflow: task breakdown
Step 1: Obtain bank feed (5 minutes)
The client's CDR bank feed is already connected through Reconlink's Basiq integration. Transactions import automatically daily. No CSV download, no email, no upload.
For non-CDR accounts, the client forwards the PDF statement to their Reconlink inbox address. Auto-import completes in 30–90 seconds.
Time: 0–5 minutes (typically 0 for CDR clients).
Step 2: Review auto-import and opening balance (10 minutes)
Confirm the transaction count matches the bank statement. Verify opening balance. Reconlink flags any gaps (missing days) or duplicate transactions automatically.
Time: 5–15 minutes.
Step 3: Review auto-coded transactions (1.5–2 hours)
Reconlink's coding engine processes all 198 transactions:
- Layer 1 (rules): 44 recurring vendor transactions coded instantly at 100% confidence
- Layer 2 (per-client ML): 88 known-vendor transactions coded at 88–95% confidence
- Layer 3 (LLM): 36 novel transactions coded at 70–85% confidence; 8 transactions below threshold, flagged for manual review
- Client income (43 transactions): Auto-coded as income (GST or FRE depending on the business) based on rules established in the first quarter
Result: 190 of 198 transactions auto-coded. 8 flagged for review.
The bookkeeper's task is to review the 190 auto-coded transactions for anomalies — not to code them individually. This is a sampling review: check all low-confidence suggestions, spot-check high-confidence ones.
Time: 50–75 minutes for review, plus 10–15 minutes for the 8 manual codings.
Total: 1 hour 15 minutes to 1 hour 30 minutes.
Step 4: Client queries via portal (15 minutes)
The 8 transactions that couldn't be auto-coded are flagged in the Reconlink client portal with a note to the client. The client sees them in their portal view and can respond with a note or upload a source document — no email required.
Time: 10–20 minutes to flag and compose notes. Client response handled asynchronously.
Step 5: BAS calculation and review (30 minutes)
Reconlink calculates the BAS worksheet automatically from the coded transactions. The bookkeeper reviews the G1-G19 totals and runs the same sanity checks as the manual workflow — now with the advantage of comparative period data built into the interface.
Time: 25–35 minutes.
Step 6: BAS draft to client (15 minutes)
Export the BAS worksheet. Send for approval.
Time: 10–20 minutes.
Total AI-assisted workflow: approximately 2.5 hours per quarter per client.
At $120/hour, that's $300 in labour cost per client per quarter. For a 10-client practice, that's $12,000/year — versus $43,200 manually. Annual saving: $31,200 in recovered capacity (or margin, if on fixed retainers).
Where the time savings actually come from
The 6.5-hour reduction per client per quarter is not distributed evenly:
| Task | Manual | AI-assisted | Saving |
|---|---|---|---|
| Statement collection | 25 min | 5 min | 20 min |
| Import / de-duplicate | 15 min | 10 min | 5 min |
| Transaction coding | 7 hr | 1.25 hr | 5.75 hr |
| Client queries | 45 min | 15 min | 30 min |
| BAS calculation | 45 min | 30 min | 15 min |
| Client draft | 20 min | 15 min | 5 min |
| Total | ~9 hr | ~2.5 hr | ~6.5 hr |
The overwhelming saving is in transaction coding — from 7 hours to 1.25 hours. This is the highest-volume, lowest-ambiguity task in the reconciliation workflow, and it's precisely what AI handles well. The tasks that require human judgement (client query management, BAS review, client communication) are reduced but not eliminated.
Caveats and honest limits
New clients take longer. In the first quarter, the AI has no coding history for the client. Auto-code rates are lower (60–65% rather than 80–85%). As the rule library matures and the ML model trains on confirmed codings, rates improve.
Complex clients benefit less proportionally. Clients with unusual transaction patterns, multiple entities, or significant manual journal requirements see smaller proportional time savings. AI coding excels at volume and pattern recognition, not at complex multi-entity intercompany reconciliation.
Rule quality matters. The first 4–6 weeks of any new client engagement require careful manual coding to build the rule library that AI will rely on. Sloppy early coding creates a rule library that auto-codes incorrectly at scale.
Review is not optional. The bookkeeper cannot simply accept all AI suggestions and send the BAS. Professional responsibility for the accuracy of the activity statement rests with the registered BAS agent, who must review AI suggestions before lodgement.
This comparison uses representative data from Reconlink's Australian practice user base. Individual results vary by client transaction mix, industry, and rule library quality. This is general guidance, not a warranty of specific time savings.
