Keep It Short & Simple • Designed by Anthony D G Mellor FCA

For the person who actually
runs the business.

Most accounting software is very good at telling you what has already happened. KISS is the persistent model of what happens next — answering how much is really yours, seeing cash shortages weeks before they hit, and giving you the steering wheel.

“AI does not make KISS obsolete. It separates KISS from its user interface.”
Sage, Xero and QuickBooks contain accounting information. AI can increasingly read and operate those systems without human help. But they do not contain the business owner’s forward decisions: when a creditor will actually be paid, when a debtor is realistically expected to pay, what cash must be protected, what can safely be extracted, or what happens when those assumptions change.

KISS is the persistent model of that future. AI can populate it, interrogate it, alter it, optimise it and explain it. The owner can manipulate it directly when that is quicker.
The Past

Accounting System

Sage, Xero, QuickBooks. Stores what has happened: historic invoices, reported VAT, statutory filings, and compliance ledgers.

The Operator

AI Financial Controller

The intelligence that connects both. Interrogates ledgers, formulates What-If simulations, drafts negotiation emails, and stages payment batches.

The Future

KISS Engine

What we currently intend to happen. Persisted model of tactical dates, buffer constraints, forward solvency protection, and “Mine”.

Core Philosophy

How Much Money is Really Mine?

An owner looks at the bank account and sees £30,000. But spending £30,000 might destroy the business three months later.

Safe Extraction Ceiling
£7,500
Calculated continuously across the entire operating cycle

Mine is not the bank balance. It is also not simply accounting profit.

It is the maximum amount the owner can extract from the business today without depriving the business of the cash needed to survive every upcoming commitment through its foreseeable cashflow cycle.

🚗

“Can I buy the car?”

Immediately shows if buying a company vehicle creates a cash trough during the quarterly VAT payment.

🏖️

“Can I book the holiday?”

Reveals the safe cash extraction figure so personal drawings never compromise payroll.

⚖️

Forward Solvency Guardrail

Monitors spendable cash against your safety cushion, alerting directors weeks before potential liquidity breaches.

⚡

Smallest Practical Change

Finds the single invoice delay or debtor acceleration that fixes a projected deficit with the least commercial friction.
