SaaS subscriptions made sense when bespoke software cost £300,000 and took 18 months. AI-accelerated development has changed that. A bespoke replacement now costs roughly one year of subscription fees, and you own it forever.
Replacing SaaS with bespoke software costs from £15,000 as a one-time build. If your team pays £20,000 or more per year in SaaS subscriptions, a custom replacement typically breaks even within 12 to 18 months. After that, you own the software outright with no licence fees, no per-seat charges, and no vendor lock-in.
Bespoke software used to be a luxury. It is now a rational financial decision for a growing number of UK SMEs.
AI-accelerated development has cut the cost of building bespoke software by 60-70% compared to five years ago. What cost £300,000 now costs £80,000. What took 18 months now takes 8-16 weeks.
If you spend £30,000/year on a SaaS tool, a bespoke replacement costs roughly £30,000 to build. After 12 months you own the software, and every month after that is money saved. The break-even used to be 6-14 years.
SaaS vendors are raising prices, gating AI features as paid add-ons, and locking customers into annual contracts. The implicit promise of continuous improvement at a stable price has broken down for most platforms.
