The verdict in three sentences
In New York as elsewhere, most late B2B payments do not come from insolvent clients but from irregular follow-up and invoices sitting in the wrong inbox. An automated collections workflow (email, SMS, text) with a payment link by card or ACH, plugged into your accounting software, costs 12,000 to 30,000 USD depending on scope. Going from a 95-day to a 60-day DSO usually frees several hundred thousand to several million dollars of cash for a mid-sized firm.
What a 95-day DSO ties up
The CFO of a professional services firm in New York tracks 400 B2B clients. Reminders are handled by one person, by phone, when time allows. The average collection period reaches 95 days, while contracts say net 30 to net 45. The formula is simple: receivables = annual revenue × DSO / 365.
| Annual revenue | Receivables at 95 days | Receivables at 60 days | Cash freed |
|---|---|---|---|
| 4,000,000 USD | 1,041,000 USD | 658,000 USD | 383,000 USD |
| 8,000,000 USD | 2,082,000 USD | 1,315,000 USD | 767,000 USD |
| 18,000,000 USD | 4,685,000 USD | 2,959,000 USD | 1,726,000 USD |
| 30,000,000 USD | 7,808,000 USD | 4,932,000 USD | 2,876,000 USD |
| 50,000,000 USD | 13,014,000 USD | 8,219,000 USD | 4,795,000 USD |
At a business line of credit rate of roughly 8 to 10% a year in 2026, 1.7 million USD freed represents about 150,000 USD of interest avoided every year.
What an automated collections system includes
| Module | Function | Indicative 2026 budget |
|---|---|---|
| Accounting software connection | import invoices and payments (QuickBooks, NetSuite, Xero) | 2,500 to 6,000 USD |
| Reminder scenarios | D-5 courtesy note, D+7, D+15, D+30, final demand | 2,000 to 5,000 USD |
| Email, SMS and text channels | templates personalised by client and amount | 2,000 to 5,000 USD |
| Payment link | card, ACH, wire instructions | 2,000 to 5,500 USD |
| Aging dashboard | 0-30, 31-60, 61-90, over 90 days, by account manager | 2,000 to 6,000 USD |
| Training and setup | finance team and account managers | 1,500 to 2,500 USD |
| Total project | 12,000 to 30,000 USD | |
| Monthly running costs | hosting, SMS, messaging fees | 300 to 900 USD |
The low scope (12,000 USD) covers email and SMS with a CSV import. The high scope adds two-way texting, integrated payment links, automatic accounting sync and a dashboard per account manager.
The practices that bring DSO down
The tool alone is not enough. Three practices make the difference. A reminder before the due date (D-5) alone cuts late payments by 15 to 25%: many invoices simply never reached the right person in accounts payable. The payment link inside the message removes the step of preparing a check or wire, which helps smaller clients a lot. Finally, every client past 60 days is escalated to the account manager, who resumes human contact.
Also plan a message for partial payments and an automatic pause on disputed invoices, so you do not damage the relationship with a client who is challenging a deliverable. In the US, keep reminders factual and compliant with state collection rules for business debts.

Maria, CFO of an 18 million USD professional services firm in New York, starts from a 95-day DSO. She invests 22,000 USD in a full system with texting and card or ACH links, plus 600 USD a month of running costs. After six months, DSO drops to 68 days, then to 60 days at twelve months. Cash freed: about 1.7 million USD. With a credit line at 9%, interest savings reach roughly 155,000 USD a year, for a year 1 cost of about 29,000 USD. Her collections specialist also recovers 2 days a week for complex accounts.
FAQ
Do B2B clients accept text reminders?
Yes, provided you have consent from the billing contact and keep a professional tone. Text open rates often exceed 90%, compared with 20 to 30% for email.
Can we collect directly through a payment link?
Yes, through a payment processor that generates one link per invoice. Card fees run around 2.5 to 3.5%, while ACH costs under 1%, often capped at a few dollars per transaction.
Do we need to switch accounting software?
No. The system connects to QuickBooks, NetSuite, Xero or a structured CSV export. The connection costs 2,500 to 6,000 USD depending on the software.
How long until it runs?
Count 5 to 8 weeks, including 2 weeks of client data clean-up (AP contacts, mobile numbers, billing emails).
What DSO is realistic?
A 60-day target at twelve months is realistic for a firm starting at 95 days. Getting below 45 days also requires revisiting payment terms and deposits.
