Why companies are swapping SaaS for AI

Traditional SaaS companies charge you per user, per month. As your team grows, your software bill skyrockets. It is one of those quiet costs that creeps up on you — you add three new hires and suddenly you are paying for three more seats across half a dozen tools.

With advanced, low-cost AI models like DeepSeek, a company can build its own basic customer service bots, data analysis tools, and writing assistants. Instead of buying ten different software tools, you route your workflows through one AI system and pay pennies for the actual computing power used. That is a fundamentally different way to think about software.

The Cost Breakdown: SaaS vs. AI

Let's look at a realistic scenario for a mid-sized company with 50 employees using standard tools for copywriting, customer support, and CRM data management.

1. The Traditional SaaS Route

• Average SaaS cost: £40 per user, per month (across 3 essential tools)
• Monthly bill: £2,000
• 6-Month Cost: £12,000
• 12-Month Cost: £24,000

That £24,000 a year buys you convenience, but it also buys you a lot of unused seats, overlapping features, and rising prices every renewal cycle.

2. The DeepSeek AI API Route

Using DeepSeek's highly efficient API models, you only pay for the volume of text generated (measured in tokens). For a team of 50 heavily using AI daily, they might process 100 million tokens a month.

• Average AI data cost: £100 per month
• Internal setup & hosting: £150 per month
• Total monthly bill: £250
• 6-Month Cost: £1,500
• 12-Month Cost: £3,000

The difference is stark: £3,000 instead of £24,000 for the same underlying needs.

The Catch: Upfront Investment

While the operational savings are massive, you must consider the initial setup. You will need to hire a developer or use an agency to build the internal interface for your staff.

If building a custom dashboard costs your company £5,000 upfront:

• Your 6-month savings adjust to £5,500
• Your 12-month savings jump to £16,000

From Year 2 onwards, the software is completely yours, and the ongoing savings go straight to your bottom line. You also avoid the annual price hikes and feature-lock that come with traditional SaaS subscriptions.
