Bank Reconciliation Skill
Pipeline: scripts/pipelines/bank-reconciliation.py Day: 2 of 14-Day Deterministic Pipeline Build
When to Use This Skill
Use when a client needs their bank account reconciled against QBO:
- Monthly close reconciliation
- Investigating GL/bank balance discrepancies
- Catching unrecorded bank fees, interest, or deposits
- Producing auditor-ready reconciliation workpapers
- Tracking outstanding checks or deposits in transit
NOT for:
- Payroll reconciliation (use payroll-recon pipeline)
- AR/AP aging (use ar-collections pipeline)
- Investment/brokerage accounts
- Intercompany eliminations
Requirements
pip install openpyxl

--out ~/Desktop/reconArguments Reference
| Argument | Required | Description |
|---|---|---|
--slug | ✅ | Company slug (must be connected in qbo-client) |
--end-date | ✅ | Reconciliation as-of date (YYYY-MM-DD) |
--bank-csv | ✅ | Path to bank statement CSV file |
--bank-ending-balance | Recommended | Bank statement ending balance (float) |
--account | Optional | Account name to match on Balance Sheet |
--bank-format | Optional | auto (default), chase, bofa, wellsfargo, generic |
--col-date | Optional | Override date column header |
--col-desc | Override | Override description column header |
--col-amount | Optional | Override single amount column header |
--col-debit | Optional | Override debit/withdrawal column header |
--col-credit | Optional | Override credit/deposit column header |
--date-window | Optional | Days for exact match window (default: 3, fuzzy: 2×) |
--out | Optional | Output directory (default: ~/Desktop) |
--sandbox | Optional | Use QBO sandbox environment |
Supported Bank CSV Formats
| Format | Date Column | Amount Column | Notes |
|---|---|---|---|
chase | Transaction Date | Amount | Negative = withdrawal |
bofa | Date | Amount | Negative = withdrawal |
wellsfargo | Date | Withdrawals + Deposits | Two separate columns |
generic | Tries common names | Tries common names | Use --col-* if fails |
Auto-detection reads column headers and picks the best format. Use --bank-format to override.
Matching Logic
Pass 1 — Exact: Amount match within ±$0.01, date within ±date-window days (default 3).
Pass 2 — Fuzzy Date: Amount match within ±$0.01, date within ±2×date-window days (default 6).
Pass 3 — Fuzzy Vendor: Amount within ±$1.00, vendor key substring match (strips check numbers, dates, ref numbers), any date.
Unmatched after all 3 passes → flagged in Unmatched tabs.
Reconciliation Equation
Book Balance (QBO BS)
+ Deposits in Transit (book has it, bank hasn't cleared it)
- Outstanding Checks (book has it, bank hasn't cleared it)
= Adjusted Book Balance
Bank Statement Ending Balance
+ Bank Credits Not in Book (bank has it, not yet in QBO)
+ Bank Charges Not in Book (negative; bank has it, not yet in QBO)
= Adjusted Bank Balance
Adjusted Book Balance = Adjusted Bank Balance → RECONCILED ✅Adjusting Entry Auto-Suggestions
The pipeline auto-classifies unmatched bank transactions into:
| Category | Keywords | Suggested Entry |
|---|---|---|
| Bank Fee | "service charge", "monthly fee", "wire fee", "nsf fee" | DR Bank Service Charges / CR Checking |
| Interest Earned | "interest", "dividend" | DR Checking / CR Interest Income |
| Direct Deposit | "payroll", "ach credit", "zelle" | DR Checking / CR AR/Revenue |
| Payment Processor | "stripe", "square", "paypal" | DR Checking / CR Undeposited Funds |
| NSF Returned | "returned item", "returned check" | DR Returned Check Expense / CR Checking |
| Unclassified | (no keyword match) | TBD — review manually |
Output: Excel Workbook
File: BankRecon_{slug}_{YYYYMMDD}.xlsx (saved to --out or ~/Desktop)
| Tab | Contents |
|---|---|
| Reconciliation Summary | Book/bank balance sections, stats, reconciled status badge |
| Matched | All matched pairs with match type (exact/fuzzy), amounts, date diff |
| Unmatched (Book) | Outstanding checks + deposits in transit (in QBO, not cleared) |
| Unmatched (Bank) | Bank items not in QBO (fees, interest, unrecorded deposits) |
| Adjusting Entries | Suggested DR/CR journal entries for each unmatched bank item |
| CDC Log | Changes since last reconciliation run (book balance, diff, etc.) |
CDC (Change Data Capture)
Cache stored at: .cache/bank-reconciliation/{slug}.json
Tracks changes in:
- Book Balance
- Adjusted Book/Bank Balance
- Deposits in Transit
- Outstanding Checks
- Reconciling Difference
On first run: "First run — snapshot saved." On subsequent runs: only changed fields shown. Saves 90%+ API calls on recurring monthly reconciliations.
Design Notes
- All financial math uses Python
Decimal— no float drift - Amount sign convention: positive = deposit/inflow, negative = payment/outflow (both book and bank)
- GL pull uses QBO
GeneralLedgerreport filtered to the reconciliation period - If GL pull fails (e.g. permissions), pipeline falls back to Balance Sheet only (matching disabled)
- Bank CSV preamble rows (Chase header lines before data) are auto-skipped
Typical Workflow
1. Client sends bank statement PDF → export as CSV from bank website
2. Run pipeline with --slug, --end-date, --bank-csv, --bank-ending-balance
3. Review Reconciliation Summary tab — check RECONCILED badge
4. If difference exists: check Unmatched (Book) for outstanding items, Unmatched (Bank) for unrecorded items
5. Post adjusting entries from Adjusting Entries tab
6. Re-run pipeline — difference should clear to $0.00
7. Save Excel to client Google Drive folder
