To clean your data before a ServiceTitan migration, you dedupe duplicate customers and locations, standardize formats (phone numbers, addresses, names, statuses), and audit for missing or junk records before anything moves over. Doing this in your old system first means ServiceTitan launches with a trustworthy database instead of importing years of mess. The golden rule of any migration is simple: garbage in, garbage out. Clean data in equals clean data out.
Why does data cleanup matter before a ServiceTitan migration?
ServiceTitan is only as good as the records you feed it. If you import duplicate customers, dispatchers book jobs against the wrong account, technicians see incomplete history, and Marketing Pro campaigns target the same person twice. A migration is the single best moment to fix this, because once bad data is live, untangling it across customers, locations, jobs, invoices, and memberships is far harder than cleaning a spreadsheet beforehand.
A clean import also protects the features you are paying for. Reporting and Dashboards, membership renewals, Service Agreements, and your Pricebook all depend on consistent, structured data to work correctly.
What data should you clean and audit first?
Focus on the records that drive day-to-day operations and revenue:
- Customers and locations - the most duplicate-prone data you own
- Active and historical jobs, plus open estimates
- Invoices and outstanding balances (especially anything still owed)
- Memberships and Service Agreements with their renewal dates
- Your Pricebook - materials, services, and pricing
- Equipment and installed-asset records tied to locations
How do you dedupe customer records?
Duplicates usually come from slight variations: "Bob Smith" vs "Robert Smith," a cell vs a home number, or two entries for the same address. To dedupe:
- Sort and group by phone number, email, and street address to surface likely matches
- Decide which record is the master and merge history into it, never deleting balances or job history
- Watch for the same physical location entered under two customer names
- Resolve duplicates in your current system before export when possible, so the cleaned version is what migrates
How do you standardize and format data?
ServiceTitan imports cleanest when every field follows one rule. Before export, standardize:
- Phone numbers to a single format
- Addresses to a consistent, ideally USPS-validated form so locations map correctly
- Names with consistent capitalization and no stray notes jammed into the name field
- Customer and job statuses to a defined list (active, inactive, lead) instead of free text
- Tags - plan your Tag list and trade categories up front rather than importing dozens of inconsistent labels
This is also the moment to map your old categories to ServiceTitan structures like Business Units, Job Types, and Pricebook categories, so reporting is clean from day one.
What should your pre-migration audit check?
Before sign-off, audit for the records that quietly break a launch:
- Missing required fields (no address, no phone, blank customer name)
- Junk and test records, plus long-inactive customers you may choose to exclude
- Open balances and unpaid invoices that must carry over accurately
- Active memberships and agreements with correct renewal dates
- Orphaned jobs or locations not tied to a real customer
Run a sample import into a staging or test environment if available, then spot-check a batch of records against the originals before committing the full load.
The honest takeaway
Data cleanup is the least glamorous and most valuable part of a ServiceTitan migration. Skipping it does not save time - it just moves the cleanup work to after go-live, when fixing it costs more and erodes trust in the system. Dedupe, standardize, and audit first, validate with a test import, and your team starts on a database they can actually rely on.
If a full data scrub feels overwhelming, a ServiceTitan Certified Provider like TradeWeave can help you plan the cleanup, mapping, and validation before launch day.
