Trades Data Migration & Systems Integration
Fifteen years of job history shouldn't die in the switch.
42 Works LLC moves customer records, job history, equipment, and open balances out of legacy contractor software and into whatever you're running now — Jobber, Simpro, ServiceTitan, Housecall Pro, ServiceTrade — then keeps that data flowing to your accounting system. Twenty years of enterprise integration work, pointed at the trades.
Who this is for
Switching platforms
You've picked the new software. The vendor's importer choked on 15 years of real-world data.
10–50 techs
Big enough that the data actually matters. Small enough that nobody has fixed it yet.
No in-house developer
You run the shop. We own the database work and the API.
Where we start
The data work nobody else will touch
Legacy data migration
Extraction from desktop-era systems: SuccessWare, ESC, Access and dBase files, old QuickBooks Desktop, homegrown SQL. Cleaned, deduped, remapped, and loaded into your new platform — customers, job history, equipment records, open balances.
Accounting & ERP sync
Field software to QuickBooks, Sage Intacct, Acumatica, or NetSuite. Invoices, POs, payroll hours, and job costing that post right the first time — then monitored, so you hear it from us before you hear it from your bookkeeper.
Reporting & data warehouse
Your operational data piped into Postgres, BigQuery, or Snowflake, with dashboards that answer the job-costing and margin questions built-in reports weren’t designed for.
Custom integration & automation
Middleware and webhook listeners for the workflows that fall between systems: supplier catalogs, pricebook feeds, telematics, and CRM.
How a migration goes
You sign off on a test load before anything touches production
Losing history is the thing owners are actually afraid of when they change software. So the migration is built to be checked at every step, by you, before it counts.
Audit the source
We open the actual database — not a sample export — and tell you what is in there: how many real customers, how much duplication, which fields survived the last upgrade and which ones did not.
Test load
Everything goes into a sandbox on the new platform first. Nothing touches production until you have seen the result.
You verify
You check the test load against your own records — your biggest accounts, your oddest jobs, the ones you know by heart. We fix the mapping and reload until it matches.
Cutover
The final load runs on your schedule, with the legacy system kept intact and readable in case anyone asks a question about 2014.
Why 42 Works
No vendor badge to protect
We're not a reseller and we're not certified by anyone, on purpose. That means when the native importer or an off-the-shelf connector will do the job, we'll tell you — and when it won't, we're the ones who can write what does. 42 Works LLC is a US-based, American-owned team built on twenty years of Salesforce and HubSpot integration and app development. Same problem, different industry: dirty data in an old schema that has to land clean in a new one.
"Every platform's migration tool works fine on the demo data. They fall over on twenty years of typos, duplicate customers, custom fields, and equipment records nobody has touched since 2009."
When something breaks, you're talking to the person who built it — not a support queue routed overseas.
Platform and product names are trademarks of their respective owners. 42 Works LLC is an independent integration firm and is not affiliated with any of them.
