What does it cost to run?
- HOSTING AND DATABASEGrows with usage; managed services cost more but save people’s time
- THIRD-PARTY SERVICESEmail, SMS, payments, maps: often priced per use
- TOOLS AND LICENCESMonitoring, code hosting, design, AI tools, per seat
- PEOPLEUsually the biggest cost by far: building, running and on call
- COST PER CUSTOMERTotal running cost divided by active customers, watched monthly
Give costs as ranges with assumptions, check them against providers’ own calculators, and watch cost per customer.
Hire, outsource or partner?
Keep in-house
- Ownership of the architecture and its decisions
- The core product that makes you different
- Knowledge of how the system really works
Outsource or partner
- Specialist, occasional work: security tests, data protection reviews
- Capacity peaks with a clear, written scope
- Operations you can’t staff around the clock
You can outsource work. You can’t outsource accountability for the architecture.
A technical roadmap the business can fund
- PHASE 1 · FOUNDATIONSSmallest version that meets the top priorities: accounts, bookings, payments, backups
- PHASE 2 · RELIABILITYIntegrations, monitoring, alerts, the first load test
- PHASE 3 · SCALEReporting, performance work, repaying the debt you chose
- REVIEWRevisit decisions, risks and costs against what actually happened
Each phase delivers customer value and reduces a named risk. Every phase has a cost and a review.
Explaining architecture to investors and boards
- THE DECISIONWhat you chose, in one sentence, with no jargon
- THE REASONWhich business priority it serves
- THE TRADE-OFFWhat you gave up, and what it costs
- THE RISKWhat could go wrong, and how you would know
- THE TRIGGERWhat evidence would make you change it
Investors don’t need to understand the technology. They need to trust the judgement behind it.
