The Cash Flow Problem
For a five-person management consultancy in Cardiff, chasing invoices was the job nobody wanted. The founder estimated she spent three to four hours every week sending follow-up emails, checking payment statuses, and making awkward phone calls to clients who were overdue.
"It's the worst part of running a small business," she said. "You do excellent work, you send the invoice, and then you wait. And chase. And wait some more. Our average time to payment was 38 days. For a small firm, that kind of cash flow gap is genuinely stressful."
The Automated Follow-Up System
We deployed OpenClaw on a hosted VPS and connected it to their Xero accounting software and email system. The agent now manages the entire accounts receivable follow-up cycle:
- Invoice monitoring — watches for new invoices in Xero and tracks their payment status daily.
- Graduated reminders — sends polite, professional follow-up emails at day 7, day 14, day 21, and day 28 after invoice date. Each message is slightly different, escalating in tone while remaining courteous.
- Payment confirmation — when payment is received, sends a thank-you message and updates internal records.
- Escalation alerts — if an invoice passes 30 days unpaid, the agent flags it to the founder with full context, suggesting next steps based on the client's payment history.
What Surprised Them
The consultancy expected faster payments. What they didn't expect was better client relationships.
"When I was doing it manually, I'd let things slide because I felt awkward chasing. So a client might not hear from us until day 25, and by then it's an uncomfortable conversation. The agent sends a friendly nudge at day 7 — before it becomes a problem. Clients actually appreciated the consistency."
Several clients commented positively on the professional follow-up process, not realising it was automated. One even asked which invoicing system they used, wanting to adopt the same approach.
The Result
Average days to payment dropped from 38 to 22 — a 42% improvement. The founder reclaimed three to four hours per week. And the emotional burden of chasing money disappeared entirely.
"I didn't realise how much mental energy it was taking until it stopped," she said. "Now I focus on delivering work, and the payments just happen. It's the single best thing we've done for the business this year."
