Fix duplicate Accounts in Salesforce by reviewing the cluster first
Duplicate Accounts are where the cleanup problem stops being annoying and starts being expensive. The wrong merge can rewrite reporting, flatten hierarchies, and send contacts and opportunities through the wrong ownership logic. So the right question is not "can the tool merge Accounts?" The right question is "how do we review the merge before we let it touch the org?"
What the code supports today
The same-object apply layer explicitly supports Account merges alongside Contact and Lead merges. That means Gremlin can execute an approved Account merge plan - but only after the cluster has been reviewed and the operator has chosen to apply it.
That distinction matters. A supported merge primitive is not the same thing as "you should bulk merge your Accounts without review." Account cleanup is higher blast radius than people-object cleanup, so the audit-first pattern matters even more.
Why Account merges need more caution
A safer Account dedupe loop
Export the Account slice you actually want to inspect.
Run enterprise-plan and write a cluster review queue.
Review survivors, anchors, and review notes in the queue before you approve anything.
Dry-run merge-apply-plan and look at skipped clusters and the receipt payload.
Apply only approved Account clusters.
Example Account planning command
g-gremlin dedup enterprise-plan \
--source Account=accounts.csv \
--output plan.json \
--review-output review_rows.csv \
--cluster-review-output review_clusters.csv \
--overwriteWhen vendor-led account cleanup can be the better fit
Account cleanup is one of the places where broader Salesforce-native tools can be the practical choice. If the job is large-scale account maintenance with richer in-org admin workflows, auto-merge options, and broader cleanup features, this is where Plauti, Dedupely, or Cloudingo may beat a narrower audit-first loop.
Dedupely
Best for: Continuous duplicate control with customizable merge rules and filters across native and custom Salesforce objects.
Good at: Admin-friendly cleanup, merge controls, and ongoing duplicate maintenance inside the Salesforce data stack.
Difference: The core mental model is in-app duplicate management, not an offline audit-first loop with plan artifacts, approval CSVs, receipts, and verify steps.
Plauti
Best for: Salesforce-native dedupe with review queues, auto-merge options, merge rules, and broader object coverage.
Good at: Accounts, Contacts, Leads, custom objects, large data volumes, and org-native operational workflows.
Difference: Plauti is built to resolve duplicates in-platform. Gremlin wins when the buyer wants an export-plan-review-apply path with explicit human gating and CLI artifacts.
Cloudingo
Best for: Admin-led Salesforce cleanup, import dedupe, and broader data hygiene tasks with no-code filters and rules.
Good at: Find, merge, prevent, import, standardize, and bulk-clean records in Salesforce and adjacent import flows.
Difference: It is a full data-cleaning toolchain, not a narrower audit-first cluster review workflow for supervised merge plans and post-run verification.
Gremlin audit-first dedupe
Best for: Operators who want to inspect duplicates before merging, review clusters in CSV or Sheets, and keep receipts on supervised apply.
Good at: Blocking-first planning, human approval queues, dry-runs, resumable execution, and Salesforce verify checks.
Difference: The public workflow is strongest for Salesforce Contact and Lead dedupe. It is not the broadest native object-cleanup platform, and I did not verify a rollback command.

FAQ
Does Gremlin support Account merges?
Yes in the same-object Salesforce apply layer. The code explicitly supports Account, Contact, and Lead merges for same-object clusters. The key point is not whether the merge can run. The key point is whether the team reviewed the cluster and understands the blast radius before live apply.
Why are duplicate Accounts trickier than duplicate Leads?
Because an Account sits in the middle of more reporting, ownership, hierarchy, and downstream association logic. A bad Account merge can reorganize more of the CRM than a bad Lead merge. That is why account cleanup should stay review-first.
When should I use Plauti or Cloudingo instead?
Use them when the job is broad native Salesforce cleanup with heavier admin workflows, larger-scale account maintenance, and broader in-org data-quality work. Use audit-first dedupe when the buyer needs cluster review, explicit approvals, dry-runs, receipts, and a plan artifact before any merge runs.
