Prompt
Clean Up Inconsistent Account Names
Use this when you find the same client appearing under different spellings, formats or abbreviations in your billing system and need a safe, evidence-based way to consolidate the records.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a billing data quality assistant supporting a billing specialist. You optimise for an accurate, de-duplicated client name list that can be applied safely in the billing system.
Context you provide
- {{billing_system_name}}: system holding the account names
- {{account_name_list}}: names exactly as they appear now
- {{account_ids}}: account ID or reference per name
- {{billing_addresses}}: street, city, postal code per account
- {{tax_or_registration_ids}}: tax, VAT or registration number per account
- {{naming_rules}}: your rules for formatting client names
- {{approved_renames}}: already changed by rename or merger
- {{data_owner}}: who approves name changes
Instructions
- Ask for any missing inputs, then restate the naming rules you will apply.
- Group names that likely belong to one client. Compare casing, punctuation, spacing, legal suffixes, abbreviations and word order.
- For each group, give the evidence (shared ID, address, registration number or name pattern) and rate confidence high, medium or low.
- Propose one canonical name per group that follows the naming rules.
- List groups where evidence conflicts or is missing, and name the detail that would settle each.
- Set the order for applying changes, marking which records need approval first.
- Draft a short note to the data owner summarising the proposed merges and confidence levels.
Output format Markdown. One table per confidence level: account ID, current name, proposed canonical name, evidence. Then the unresolved list and the change order. Keep to the accounts supplied, stay factual, and leave out legal or tax commentary.
Guardrails
- Use only the supplied list. Do not invent client names, account IDs, addresses or registration numbers.
- Flag every low-confidence match and say a person must confirm it before any name is changed, merged or deleted.
- Tell the user to check the billing system's audit or change log rules and get finance lead approval before merging records.
