Account reconciliation and bank reconciliation — two pillars of finance in Türkiye. Both have "reconciliation" in the name, both sit at the heart of the monthly close, yet they do different things. They are confused all the time, and confusion is where errors grow.
This article explains the clear differences between the two types of reconciliation, how each process works, and when each one matters.
Definitions
Account reconciliation
Definition: The mutual verification of a customer or supplier account in your ledger against the account that person or company keeps about you.
Example:
- In your ledger: "Customer Acme A.Ş. owes me 145.000 TL."
- In Acme A.Ş.'s ledger: "I owe 145.000 TL."
- Reconciled ✓
For a detailed definition, see: What is reconciliation — the complete guide.
Bank reconciliation
Definition: Verifying the bank account balance in your company ledger against the statement the bank provides you.
Example:
- In the ledger: "Garanti account balance: 845.230 TL."
- Garanti statement: "Account balance: 845.230 TL."
- Reconciled ✓
7 clear differences
| Criterion | Account reconciliation | Bank reconciliation | |---|---|---| | What is compared | Your ledger vs the customer/supplier ledger | Your ledger vs the bank statement | | Frequency | Monthly or quarterly | Daily, weekly, or monthly | | Data source | Two separate company ledgers | Bank API or statement | | Number of sources | 2 (you + counterparty) | 2 (you + bank) | | Automation difficulty | High (counterparty coordination) | Low (bank API) | | Audit significance | Proving the relationship | Verifying the balance | | Turkish regulation | TTK 64 (Turkish Commercial Code), VUK 219 (Tax Procedure Law) | TTK 64, VUK |
The account reconciliation process
1. Prepare the account statement Pull the customer/supplier account summary from your ledger. In date order:
- Invoice date + amount + description
- Payment date + amount + description
- Balance
2. Send it to the counterparty You send your account statement to the customer or supplier, with a message along the lines of: "Here is what our ledger shows — what does yours say?"
3. The counterparty's response The counterparty sends their own statement. The balances are compared.
4. Difference analysis If the balances differ: which transactions are missing or wrong?
5. Correction The record both sides agree on is corrected.
6. Reconciliation report A mutually signed reconciliation report ("mutabakat tutanağı") is drawn up and retained as evidence for audits by the KGK (Turkish Public Oversight Authority).
Our KGK audit readiness article covers the audit dimension of this process in detail.
The bank reconciliation process
1. Download the bank statement The statement is pulled via bank API or manually.
2. Compare against the ledger's bank records Does every bank transaction have a counterpart in the ledger?
3. Matching Bank transactions ↔ ledger records, matched automatically or manually.
4. Identify differences Unmatched transactions are reviewed one by one.
5. Update the records Missing entries are added; incorrect ones are corrected.
6. Confirm the balance Ledger balance = bank balance.

Which one, when?
Account reconciliation should be done:
- ✅ Monthly or quarterly (for key customers/suppliers)
- ✅ At year-end close — without exception
- ✅ Ahead of a KGK audit
- ✅ When a customer is resisting payment
- ✅ For export transactions
Bank reconciliation should be done:
- ✅ Daily (large companies)
- ✅ Weekly (mid-sized SMEs)
- ✅ Monthly at the very latest
- ✅ Daily, no exceptions, during year-end close
- ✅ For items involving FX differences against the official rate of the CBRT (Central Bank of Türkiye) (details)
5 points that get confused
Confusion 1: "The customer paid me, so reconciliation is done"
Wrong: A payment showing up on your bank statement does not complete account reconciliation. Does the invoice you issued actually appear in the customer's ledger?
Confusion 2: "My bank balance matches my ledger, so we're fine"
Wrong: Bank reconciliation is not just balance matching — every transaction must be categorized and assigned to the correct account code.
Confusion 3: Account statement = bank statement
Wrong: An account statement is two-sided (you and the customer/supplier). A bank statement is two-sided (you and the bank). Different contexts.
Confusion 4: "Account reconciliation is a year-end job"
Wrong: For key customers and suppliers it should run monthly. Year-end is far too late — errors that pile up during the year can no longer be corrected.
Confusion 5: "Bank reconciliation is accounting's job"
Wrong: Bank reconciliation is the responsibility of treasury or financial management. The accountant keeps the records; finance does the reconciliation.
The automation approach
Automating account reconciliation
Hard, because:
- It requires coordinating with the counterparty
- A manual "send statement + wait for a reply" loop
- The reconciliation report is an official document
The iFinances approach:
- Automatic account statement generation (PDF, email-ready)
- A customer portal (for larger companies)
- Account anomaly detection — differences flagged automatically before reconciliation even starts
Automating bank reconciliation
Easy, because:
- Bank APIs are available
- Automatic matching is feasible
- Eight major banks in Türkiye offer APIs
The iFinances approach:
- Native APIs for Garanti, İş, Akbank, Yapı Kredi, Ziraat, Halk, QNB, and TEB
- File support (.xlsx, .csv, .mt940) for banks without an API
- A 6-layer matching engine (rules + fuzzy + ML)
- Details: Modules.
Automation ROI
Annual savings for an SME with 50M TL in revenue:
| Item | Manual hours | With automation | Savings | |---|---|---|---| | Monthly account reconciliation (50 customers/suppliers) | 80 hours | 12 hours | 68 hours/month | | Monthly bank reconciliation | 24 hours | 2 hours | 22 hours/month | | TOTAL | 104 hours | 14 hours | 90 hours/month | | Annual | 1,248 hours | 168 hours | 1,080 hours (roughly 1.5 FTE) |
5 frequently asked questions
Q: Is there a penalty for skipping account reconciliation?
A: No direct penalty. But if reconciliation reports are missing in a KGK audit, you receive an audit finding — which hurts both your credit standing and the audit report.
Q: How often should bank reconciliation run?
A: Large companies daily, mid-sized SMEs weekly, small SMEs monthly. During the year-end season, daily without fail.
Q: Is there a standard format for account statements?
A: There is a general form under the TTK, but no strict standard. Formats can vary by industry.
Q: Which software handles both?
A: Most modern reconciliation software, iFinances included, supports both. Details: E-reconciliation software 2026 comparison.
Q: What happens when an error is found?
A: A correcting entry is posted, your accountant is informed, and the audit trail is updated. Details: The balance-sheet impact of reconciliation errors.
Conclusion
Account reconciliation and bank reconciliation are processes that serve different purposes yet complement each other. Running both disciplines well is the foundation of audit-ready financial operations.
