If you're running an accounts receivable company, you already know the problem: CFOs and controllers are buried. They're managing cash flow, dealing with delinquent accounts, and juggling multiple vendors. Cold email to them feels like screaming into the void.
The real issue isn't that they don't need you. Most mid-market companies are leaving money on the table with their AR processes - slow collections, manual follow-ups, accounts falling through cracks. The problem is they don't know you exist, and worse, they don't trust that you'll actually solve their specific problems without making their workflow harder.
Here's what actually works for AR companies: stop selling your service, and start selling the specific dollar amount they're probably losing right now.
Find the Right Person - And Make Sure They Care About This
Most AR companies target anyone with "finance" in their title. That's too broad and wastes sends. You need CFOs, controllers, or accounting managers at companies with enough revenue to have AR problems worth solving.
The sweet spot: companies doing $5M-$100M in annual revenue with B2B sales models. These companies have enough invoices and customers that manual AR is painful, but they're not yet big enough to have built their own AR automation.
When building your list, filter for these three things:
- Industry vertical - target B2B service companies first (agencies, consultants, software resellers, staffing). They have the highest average days sales outstanding (DSO) and the most fragmented customer bases.
- Company size - $10M to $75M revenue. Below that, they're still managing AR with spreadsheets and don't think it's a problem yet. Above that, they've already bought expensive solutions.
- Job title - CFO, VP Finance, Controller, Accounting Manager. Skip AR specialists themselves - they're not decision makers on new tools.
Use LinkedIn Sales Navigator or a data provider like Apollo or ZoomInfo. The search should take 30 minutes per vertical. You're looking for real people, not title-scraped lists.
The Email Structure That Works
Your subject line needs to do one thing: signal that this is about money they're losing, not another software pitch.
Subject: Quick question on your DSO
That's it. Three words. No emoji, no urgency language, no hyphens. DSO (Days Sales Outstanding) is their metric. Using it signals you actually work in this space.
The opening line is where you prove you've actually looked at them. Not a generic compliment - a real observation tied to their business model.
Hi [Name], I was looking at your site and noticed you work with a lot of enterprise clients - those probably take 60+ days to pay. Quick question: when you see a 90-day invoice, how many touches does it usually take to collect?
This works because:
- It's specific to their business (enterprise clients). You've looked at their website.
- It's a real question, not a pitch. You're asking about their process.
- You're naming the pain point they deal with every day (long payment cycles).
- You're not selling - you're diagnosing.
The middle section introduces what you do, but only in context of their specific situation:
The reason I ask is we work with companies like you - mostly in [your vertical], $20-80M ARR - to cut their DSO by 15-20 days on average. That usually means $200-400K in freed up cash per year.
Notice: you're naming the specific number (15-20 days), the specific dollar impact ($200-400K), and the specific company size you work with. Not vague benefits. Real numbers they can do the math on.
Close with one simple CTA:
Worth a quick call to see if we could do something similar? I can grab 15 minutes next Tuesday or Wednesday.
No links. No attachments. No "let me know your availability" (they won't respond to that). You're offering a specific time. Take the friction out of saying yes.
Segment Your Sequences by Industry Pain Points
A staffing company's AR problem is different from a consulting firm's. Staffing companies deal with high volume, low-value invoices. Consulting firms have fewer invoices but bigger amounts and longer terms. Your follow-ups should reflect that.
Build two separate sequences:
Sequence 1: High-volume, low-value models (staffing, recruiting)
- Email 1 (Day 0): Lead with volume problem - "with 200+ invoices a month, how many do you manually chase?"
- Email 2 (Day 3): Talk about billing accuracy - "one data entry error on a high-volume invoice batch probably costs you hours in back-and-forth"
- Email 3 (Day 7): Case study angle - name another staffing company and their DSO improvement
Sequence 2: Low-volume, high-value models (agencies, consultants)
- Email 1 (Day 0): Lead with client retention - "when a $50K invoice takes 120 days to collect, it changes your cash position and sometimes client relationships"
- Email 2 (Day 3): Talk about negotiation leverage - "earlier visibility into payment trends lets you push back on payment terms before they become problems"
- Email 3 (Day 7): Data-driven angle - their industry's average DSO vs. best-in-class
Both sequences are short. Each email is 3-4 sentences. You're asking about their process, not pitching features.
Timing and Frequency Matter More Than You Think
CFOs and controllers don't check email at 9 AM on Monday. They're in meetings. Send at 2-3 PM on Tuesday through Thursday. They're catching up on messages between meetings.
Space your sequence at 3-day intervals, not daily. They're not ignoring you - they're busy. Give them time to notice, think about it, and respond.
And here's the thing most AR companies miss: don't follow up the same person more than 3 times. If they haven't responded after 3 emails across 2 weeks, they're not interested right now. Move to the next prospect. You're looking for people actively thinking about AR, not everyone with a finance title.
What Actually Converts
When they reply, they'll ask questions like: "How much does this cost?" or "Do you integrate with our accounting software?" or "Can you handle our specific invoice types?"
Answer in 2-3 sentences, then ask for the call. Most replies are actually interest signals - they're asking because they're considering it. Get them on the phone.
On the call, don't demo. Ask about their AR process. What's their DSO? How many people touch each invoice? What percentage of invoices need manual follow-up? Let them sell themselves on why they need this.
The Gap Between Reading This and Running It
You now know the framework: find the right people, lead with their specific pain points, use real numbers, space your emails right, and close on a call. It works.
The gap is this: building clean lists, writing sequences that actually work for your specific vertical, setting up infrastructure that doesn't land you in spam, handling replies as they come in, and scaling this to 50+ sends per week without burning out.
If you want this running well without building it yourself, that's what we do - we handle the list building, copy, sending, and reply management for B2B service companies. You focus on closing deals.
