The verdict in three sentences
Beyond 500 active clients, manual follow-up by email and phone breaks down: small invoices get forgotten and key accounts are chased too late. An automated collections tool at USD 12,000 to 25,000, synced nightly with Sage Intacct or QuickBooks, sends email and SMS sequences tailored to each client profile. Moving from 94 to 60 days sales outstanding frees about USD 400,000 of cash in this case, without hiring.
Where a services company's cash goes
The CFO of a New York B2B services company (facility maintenance, 1,100 clients) reports 94 days sales outstanding on net-30 terms. Two accounting staff chase payments when they have time, from an Excel export of the aging report.
| Metric | Current situation | 6-month target | Main lever |
|---|---|---|---|
| Days sales outstanding (DSO) | 94 days | 60 days | Reminder from D-5 before due date |
| Invoices followed up on time | 35% | 100% | Automated sequences |
| Accounting time spent on collections | 25 hours a week | 8 hours a week | Only disputes stay manual |
| Balances over 90 days | USD 700,000 | USD 250,000 | Automatic escalation to account manager |
| Disputes identified late | 1 in 3 | 1 in 10 | "Dispute" button in the email |
| Cost of credit line | 8 to 10% per year | Sharply reduced | Freed cash |
Solutions compared, 2026 costs
| Option | Setup | Monthly cost | Timeline | Limit |
|---|---|---|---|---|
| Manual follow-up with Excel | None | 2 part-time roles (about USD 6,000) | Immediate | Irregular, depends on vacations |
| Native dunning in the accounting system | USD 2,000 to 5,000 | Included in licence | 2 weeks | Fixed templates, no SMS |
| AR automation SaaS | USD 3,000 to 10,000 | USD 500 to 2,500 | 3 to 4 weeks | Per-seat pricing grows with the team |
| Custom collections tool connected to accounting | USD 12,000 to 25,000 | USD 300 to 700 (hosting, SMS) | 6 weeks | Requires scoping of client profiles |
| Collection agency | None | 15 to 30% of amounts collected | 2 weeks | Expensive and risky for the relationship |
The custom tool reads invoices and payments from the accounting system every night, sorts clients into profiles (key accounts, regular SMBs, late payers, public sector) and triggers different sequences: courteous reminder at D-5, follow-up at D+3, SMS at D+10, account manager call at D+20, formal demand at D+45. Each email includes the PDF invoice, an ACH or card payment link and a button to flag a dispute, which opens a task in the CRM. SMS sequences require documented consent under the TCPA.
Mini case study
Michael, CFO of a services company in New York, bills USD 4.3 million a year, about USD 11,800 collected per day. Cutting DSO from 94 to 60 days, 34 days fewer, frees 34 times USD 11,800, so about USD 400,000 of cash.
At a 9% credit line rate, that is USD 36,000 of interest saved per year. Add 17 hours a week of accounting time recovered, about 750 hours a year at USD 45 per hour, so USD 33,750. The project billed at USD 20,000 plus USD 500 per month pays back in about 4 months on these gains alone, not counting fewer write-offs.

How much does accounts receivable automation cost in 2026?
Plan USD 12,000 to 25,000 for a custom tool connected to your accounting system, then USD 300 to 700 per month for hosting and SMS. Native dunning modules cost less, USD 2,000 to 5,000, but remain limited.
Does automated follow-up hurt client relationships?
Quite the opposite, a courteous reminder 5 days before the due date settles many delays without tension. Key accounts can get a softer sequence approved by their account manager.
Do we need to change accounting software?
No, the tool reads data from Sage Intacct, QuickBooks or any system with an API or export, and posts matched payments back. Sync runs nightly or hourly.
What results can we expect, and how fast?
The tool is live in 6 weeks. First DSO effects appear after one billing cycle, and the 60-day target is realistic within 4 to 6 months, without guarantee since it also depends on client mix.
Can late fees be calculated automatically?
Yes, the tool computes contractual late fees on each overdue invoice and can mention them in reminders. Whether to actually bill them remains a commercial decision for the CFO.
