As a Salesforce admin who’s managed orgs for Fortune 500 companies in healthcare, finance, and retail, I’ve seen too many preventable mistakes drain budgets. These aren’t "oops" moments—they’re direct cash leaks. Here’s what I’ve seen cost companies real money.
1. Over-Engineering Custom Objects
Every time you create a custom object instead of using standard objects or standard fields, you’re adding storage costs, slowing queries, and complicating future upgrades. A retail client built 47 custom objects for "product variants" when Salesforce’s standard Pricebook and Product2 objects would’ve sufficed. Result: $12,000 in annual extra storage costs and 40% slower reporting. They could’ve avoided this by auditing standard capabilities first.
2. Ignoring Sharing Settings
Setting sharing to "Public Read/Write" on a sensitive object isn’t just risky—it’s expensive. A financial services client configured a custom "Loan Application" object as "Public" (not realizing it held SSNs and credit scores). When a breach exposed 2,000 records, they faced a $50,000 GDPR fine and $15k in legal fees. Always use "Private" as the default and audit sharing weekly with this SOQL:
SELECT Id, OrganizationId, AccessLevel, ParentId
FROM ObjectPermissions
WHERE ParentId IN (SELECT Id FROM CustomObject WHERE NamespacePrefix = 'my_namespace')
3. Misusing Workflow Rules
Workflow rules trigger emails, field updates, and more—but overuse burns email credits. A SaaS company set up a workflow to send a "welcome email" on every new user creation (fine). Then, they accidentally added a field update that triggered it for all 10,000 existing users. They paid $800 for 10,000 extra emails (Salesforce charges $0.08/email). Fix: Test workflows in sandbox before deployment and limit email triggers to new records only.
4. Forgetting Soft Deletes
Not enabling soft deletes means accidental deletions require costly, manual recovery. A healthcare client deleted 5,000 patient records (Accounts) because "Delete" was the only option. They paid $22,000 to Salesforce’s data recovery team—$12k for the service plus $10k in lost productivity while waiting. Always enable "Soft Delete" in Setup > Data Management. It’s free and prevents this.
5. Leaving Unused Fields/Custom Settings
Every unused field bloats your org. A manufacturing client had 217 custom fields on Accounts, many from legacy projects. This slowed API calls (costing $3k in extra Salesforce API credits) and caused a 30% delay in lead assignment. Use this SOQL to find unused fields:
SELECT QualifiedApiName, NamespacePrefix
FROM CustomField
WHERE IsActive = true
AND LastModifiedDate < LAST_MONTH
AND (SELECT COUNT() FROM FieldPermissions WHERE ParentId = CustomField.Id) = 0
These mistakes aren’t about skill—they’re about process. I’ve seen teams waste $100k+ in avoidable costs because they skipped audits, ignored documentation, or rushed deployments. The fix
