Frequently asked questions
What's the difference between SaaS and a custom bot?
A SaaS platform (like Chatfuel, WATI, or ManyChat) is a ready-made system with a monthly subscription — fast to set up but limited in customization and expensive over time. A custom bot is built specifically for your business with a one-time payment — takes longer to set up but gives you full control and lower long-term costs.
Why choose a one-time payment over a monthly subscription?
A one-time payment saves 33-50% over 2 years. For example: SaaS at $200/month = $4,800 in 2 years. A custom bot at $2,000 + $50/month hosting = $3,200 in 2 years. That's $1,600 saved — and the savings grow every year after that, since you only pay hosting.
What if the vendor shuts down?
With a custom bot — the code is yours. Any developer can pick it up and continue the work. With a SaaS platform — if the vendor shuts down, your bot stops working and you have to start from scratch. Code ownership is a critical factor for business continuity.
When should I choose SaaS?
SaaS is a good fit when you need a solution up and running within hours, have a simple use case with no complex integrations, and prefer not to deal with any technical setup. It's ideal for businesses testing the waters with chatbots before committing to a full custom build.
What's the difference between Achiya and Chatfuel/WATI?
Chatfuel and WATI are global SaaS platforms with monthly subscriptions, English-only interfaces, and pre-built templates. Achiya Automation builds fully custom solutions — one-time payment, full code ownership, unlimited integrations, and native Hebrew + English support. You get a bot built exactly for your business, not a one-size-fits-all template.
Why not just use ManyChat?
ManyChat is great for social media marketing, but limited in complex integrations, doesn't support Hebrew natively, and requires a monthly subscription. If your business needs CRM integration, appointment scheduling, payment processing, or multilingual support — a custom bot delivers a more precise and cost-effective solution.
