Inventory every place an adjustment can appear

Inspect transaction pages, charge and interest summaries, account messages, overdraft sections, cumulative figures, and every continuation page. Because one fee may appear both as a row and a summary component, understand presentation before totaling values.

Capture the source label verbatim with date, value, direction, page, and section. Keep service, ATM, overdraft, and returned-item fees, interest, refunds, corrections, and promotional credits separate until verified.

Reconcile line items with statement fee totals

Total fee rows for the covered period and compare the result with the printed period figure. Year-to-date totals belong to a different boundary and must not be added to current-period fees.

An embedded ATM operator charge, another statement section, a reversal, or a different category definition may explain a variance. Never invent an offsetting fee solely to force agreement.

Reconcile fee rows to the correct summary period. Suppose the ledger contains 8.00 and 12.00 of service charges while the statement's current-period fee total is 20.00 and a year-to-date box shows 76.00. The 76.00 is context, not another charge to add. Record which rows make up the 20.00 and inspect any difference for a reversed fee, an ATM operator charge embedded in a withdrawal, or a fee presented on another page. Never create a balancing fee merely because a summary does not agree.

Separate interest earned from interest charged

Earned interest is incoming activity, whereas charged interest is a cost. Preserve account type, printed rate when available, covered period, balance basis, and any cumulative or tax-related fields without guessing the bank's calculation method.

Attempt recalculation only with sufficient inputs and a verified method. Simple balance multiplied by rate can differ because of compounding, daily balances, tiers, cutoff rules, or account-specific terms.

Fee and adjustment exception ledger

Give every questioned item its own row and keep the original statement evidence linked throughout review.

Source entry

Retain label, date, value, direction, page, section, and any linked transaction.

Rule and calculation

Cite the account term, printed total, balance basis, rate, or bank explanation used.

Review action

Assign an owner and log official contact, requested evidence, response date, and next deadline.

Closure

Attach evidence to whichever status applies: accepted, reversed, refunded, disputed, corrected, or unresolved.

Trace overdrafts and returned items to the triggering activity

Where evidence permits, link an overdraft, insufficient-funds, or returned-item charge to the triggering payment or balance event. Record balance type, authorization and settlement dates, posting order, and connected reversal or refund.

Product and jurisdiction affect applicable rules and disclosures. The statement proves the charge but may omit facts necessary to evaluate calculation or disclosure, so consequential disputes should follow the institution's official channel.

Link correcting entries back to their verified source events

Do not assume a credit correction is income or a debit correction is routine spending. Test value, reference, counterparty, payment channel, and timing against the original event while retaining both postings.

Use a relationship table for partial refunds or multiple corrections instead of editing the source value. Verify combined balance movement and keep any unmatched remainder visible.

Represent corrections as relationships between posted rows. A 140.00 purchase followed by a 40.00 partial refund should remain a 140.00 debit and a linked 40.00 credit, not a rewritten 100.00 purchase. The gross view supports reconciliation, while a disclosed net view can support spending analysis. Record original entry, correction, remaining amount, reference, date, and status. This same structure handles full reversals, several partial credits, and corrections that post in a later statement period without erasing the account history.

Close each exception with evidence

For each questioned item, log the source row, review reason, disputed value, relevant disclosure or term, official contact route, response, correction date, and status. Retain messages or screenshots only when permitted and protect their sensitive data.

An unresolved fee should remain identifiable rather than disappear into miscellaneous spending. Keep the exception open until acceptance, refund, correction, official escalation, or another dated evidence-based closure.

When the interest appears on a revolving card account, use the credit card interest and APR review instead of applying deposit-account assumptions.
