Budget & Total Cost of AI

Total cost of ownership (TCO)

The monthly SaaS fee is often the smallest line item. Real cost includes: staff time to set up, learning curve, data cleanup, integration work, and ongoing maintenance.

Budget for 12 months, not just the launch month.

Typical cost categories

• check_circleSubscriptions — $0–30/user/month for most SME AI tools; team plans add up
• check_circleImplementation — DIY (your time) vs contractor/agency (one-time project fee)
• check_circleTraining — 2–4 hours per staff member to learn approved workflows
• check_circleIntegration — API development, WhatsApp Business API, website chat widgets
• check_circleMaintenance — bug fixes, prompt updates, vendor changes, security patches

Realistic ranges for small businesses

• check_circleDIY tool stack — $0–100/month + founder time
• check_circleLight integration (website form → AI summary email) — low hundreds USD one-time
• check_circleCustom app with MoMo, ordering, admin dashboard — project-based; scope with a local partner
• check_circleEnterprise compliance setup — significantly higher; only if regulation requires it

Build a simple ROI case

Example: Staff spends 10 hours/week on repetitive WhatsApp replies at an effective cost of RWF 50,000/week. If AI-assisted replies cut that to 4 hours, you save ~RWF 30,000/week — ~RWF 120,000/month.

Compare that to tool costs + setup. If savings exceed cost within 3–6 months, the pilot is worth running.

Hidden costs to watch

• check_circlePaying for unused seats after staff turnover
• check_circleDuplicate tools (three people on different AI accounts with no sharing)
• check_circleVendor lock-in — exporting data before you depend on one platform
• check_circleShadow IT — staff using personal ChatGPT accounts with customer data
