Building a Curated Contact List of CPAs & Bookkeepers in Central Texas (Google Maps and AI Enabled)
The Challenge
A client approached us with a targeted outreach need: They wanted to connect with Certified Public Accountants (CPAs) and bookkeepers in Williamson County and Travis County, Texas.
However, they lacked a reliable, up-to-date list of contacts. They had tried gathering data from online directories and networking events but found it time-consuming and incomplete.

Pain points:
Scattered and outdated online business listings
No centralized directory of active professionals in the target region
High risk of sending outreach to firms that were closed or had invalid contact details
Our Process
1. Targeted Web Scraping & Research
We began by collecting data from a combination of reliable online sources:
Google Maps & Business Profiles
Professional directories
Chamber of Commerce listings
LinkedIn company profiles
We scraped and cross-referenced this data to extract:
Business Name
Street Address
Contact Name (owner or managing partner where available)
Professional Email Address
Removed secondary office locations
Result: An initial raw list of 150 unique firms across the two counties from Google Maps with data reformatted by ChatGPT.
2. Business Verification & Email Testing
Before handing over the data, we verified:
Business status as Open (closed/inactive were moved to separate sheet)
Email validity through a test email message
Manual confirmation through website links or LinkedIn activity where needed
Twenty-one (21) firms were identified as no longer in operation or unreachable via their provided contact details
Final list contained 129 verified, active CPA/bookkeeping firms
3. Delivery & Client Enablement
The final contact list was delivered in Excel format, ready for direct use in CRM tools or outreach platforms. The list included:
Field | Description |
Business Name | Full registered company name |
Street Address | Mailing address for physical mailings |
Contact Name | Primary owner or managing contact |
Email Address | Verified business email |
Website URL | Website URL |
The client could sort, segment, and target contacts with ease.
Outcome & Impact
The client received a clean, verified list of 129 local firms
Enabled precise targeting for outreach campaigns
Saved the client an estimated 15+ hours of manual research
Avoided email bounces and wasteful communication with closed businesses
Client Testimonial
“This list was exactly what we needed—clean, accurate, and ready to use. We launched our outreach the next day without a hitch. It’s the kind of groundwork that’s hard to do well on your own.”
