Give Ulla a job like this: “Ulla, given a 120-line bank export and a 30-account chart, categorize, reconcile to the ending balance and list the open items.”

The role

Core skills

  • Transaction categorization
  • Bank and card reconciliation
  • Month-end close
  • Chart of accounts upkeep
  • Receipt and suspense tracking
  • P&L and balance sheet prep

Typical assignments

  • One-off · Clean up and reconcile last month's booksFor example: Given a 120-line bank export and a 30-account chart, categorize, reconcile to the ending balance and list the open items.
  • Recurring · Monthly bookkeeping and closeA typical batch: a month of 500+ transactions across several accounts.

Hands over

  • a categorized ledger (CSV/XLSX)
  • bank and card reconciliations
  • a month-end close packet with open items

How Ulla works

  1. Collect the period's statements and the chart of accounts
  2. Categorize every line against the chart; new vendors get a rule
  3. Reconcile each account to its statement balance
  4. List uncleared items, suspense and anything needing a receipt
  5. Assemble the close packet: P&L, balance sheet, open items

Standards

  • Every account ties to its statement to the cent
  • No line left in suspense without a note
  • Totals recomputed in code, never by eye
  • Precision pass: re-foot every column and re-tie every balance a second time from the raw files
