The Problem
Jobs getting done. Clients happy.
Cash flow unpredictable. Admin eating weeks alive.
Invoices sent days late — whenever he 'got round to it'
Follow-ups forgotten entirely
Payments slipping weeks behind
~25 hours/week lost to zero-value admin
The Constraint
The problem wasn't Xero.
It was manual dependency.
As long as invoicing relied on him noticing, remembering, and chasing — it was never going to run properly. But who can be arsed to send invoices on a Friday night after a week on the tools? You'd rather be in the pub. Fair enough.
So we removed him from the process entirely.
The System
Lightweight automation.
Built around how he already worked.
System watches CRM for completed jobs
Invoice generated in Xero instantly — no delay
Unpaid after 48hrs → follow-ups via SMS & WhatsApp
No new tools, no behaviour change, no dashboards
The Proof
Same business. Same Xero.
Before and after.
+£2,955 projected. £0 outstanding.
Same 30-day window. Different system.
The Result
25 hours a week reclaimed
Four figures in recovered revenue
Cash flow stabilised
Invoicing out of his head
Same clients. Same pricing. Same workload. One system removed the bottleneck.
Who This Is For
Trade and service businesses doing £7.5k–£10k+ per month — where the work gets done, but admin and cash flow lag behind.
If invoicing still depends on you remembering, you're paying for it.
