Short answer: Controllers and accounting managers run day-to-day finance operations: the monthly close, accounts payable and receivable, reporting and audit preparation. They often evaluate and champion tools that the CFO later approves. Map the accounting team at each target account, use the titles that fit the company's size, find and verify contact details, and time outreach away from month-end and year-end close. Keep CAN-SPAM, TCPA and do-not-call rules in mind.
Why controllers matter in B2B deals
If you sell accounting, AP automation, spend management, payroll, tax, audit, FP&A, ERP or billing software, the controller is often the person who feels the pain most. CFOs set strategy and approve budgets, but controllers and their managers run the processes. Reaching them directly can lead to better discovery and a stronger internal champion.
Step 1: Map the accounting team by company size
| Company size | Typical titles |
|---|---|
| Small business | Office Manager, Bookkeeper, Accounting Manager, outsourced accountant or fractional CFO |
| Growth-stage and mid-market | Controller, Assistant Controller, Accounting Manager, Senior Accountant, AP or AR Manager |
| Enterprise | Corporate Controller, Chief Accounting Officer, Division Controllers, Director of Accounting, Shared Services leaders |
Related titles to watch for include Director of Finance Operations, Revenue Accounting Manager, Payroll Manager and Tax Director, depending on what you sell.
Step 2: Choose target segments
Filters that help:
- Industry, for example SaaS, manufacturing, healthcare, construction, retail or professional services
- Headcount and revenue bands
- Location, such as New York, Chicago, Dallas, Atlanta, Charlotte, Denver or Phoenix
- Signals such as a new controller hire, finance job postings, an ERP migration or recent funding you can verify
Companies that are scaling quickly or preparing for an audit or financing round often feel finance process pain.
Step 3: Build the contact list
- Search professional networks for controller and accounting titles at your target accounts
- Check job postings; finance roles often mention who they report to
- Look at company leadership pages, though controllers may not be listed
- Confirm each person is current
- Map two to four contacts per account: for example the CFO, controller and an AP or accounting manager
Step 4: Find and verify contact details
- Use a contact finder you have tested on a sample of finance contacts
- Verify work emails and pilot-send small batches
- Dial-test a sample of direct numbers
- Remove people who have moved; finance teams can turn over after audits or acquisitions
- Track the source of each contact
Step 5: Time outreach to the finance calendar
Controllers are busiest during:
- Month-end close, often the last few days of a month and the first week or two of the next
- Quarter-end and year-end close
- Audit fieldwork
- Tax deadlines that apply to their company
Mid-month is often a better time for outreach. Shorter emails and a clear ask help when people are busy.
Step 6: Write relevant outreach
- Focus on concrete process pain: close timelines, manual reconciliations, approvals or reporting
- Use plain finance language rather than vague transformation messaging
- Mention integrations with systems they likely use, if your product has them
- Offer a short walkthrough or a useful checklist rather than a long demo request
Step 7: Measure and refine
Track usable contact rate, replies and meetings by title and segment. Controllers may reply less than other roles but can become strong champions when the fit is right.
Compliance (high level)
Follow CAN-SPAM for commercial email: accurate sender details, a physical address and a working opt-out. For calls or texts to mobile numbers, consider TCPA and do-not-call rules. Applicable privacy laws may also apply. Honor opt-outs promptly.
Common mistakes
- Pitching only the CFO and ignoring the people who run the process
- Reaching out during month-end close
- Using generic finance buzzwords
- Mixing up corporate controllers with project or plant controllers in industries like construction and manufacturing
- Skipping verification on older lists

FAQ
What is the difference between a controller and a CFO?
A CFO usually owns finance strategy, capital and investor relations, while a controller runs accounting operations such as the close, reporting and controls. In smaller companies one person may do both.
When is the worst time to contact a controller?
During month-end, quarter-end or year-end close and during audit fieldwork. Mid-month is usually better.
Who handles accounting at small companies without a controller?
Often a bookkeeper, office manager, accounting manager or an outside accounting firm or fractional CFO.
Should I contact the controller or the CFO first?
It depends on your product. For process tools, starting with the controller can lead to better discovery, with the CFO brought in for budget approval.
How many finance contacts should I map per account?
Two to four is a practical range, such as the CFO, the controller and an accounting or AP manager.
