The short version
Guestline, now part of Access Hospitality, offers a hotel system, distribution, a booking engine, payments, EPoS, revenue management and event management to more than 3,500 hoteliers. mDOS covers the hotel side too, with front desk, night audit, housekeeping, digital check-in and a channel manager, and puts table booking, guest marketing, reviews, loyalty (Beta) and your website in the same system, at one price per site with every feature included. Choose on how you want to grow direct bookings and how much you want working for you between shifts.
How our software compares
This compares our software’s features only. Our AI agents and our partner Marketing Experts come on top, and no single tool here includes them. Every mDOS line is live today unless it says Beta. Every Guestline line comes from Guestline’s own website; “Not listed” means we couldn’t find it there. Checked on 9 Oct 2026; sources are listed below.
And on top of the software: AI agents that do the legwork, and vetted Marketing Experts running it with you. No single tool compared here includes them.
Where mDOS is stronger
- Fixed pricing: one price per site with every feature included, so no surprise per-user or per-module costs.
- Marketing tools included in every plan: SEO, AI search, social media, Google Business Profile, paid ads, digital PR (Beta) and visitor intelligence. Run them yourself, with the AI team (Beta), or let our marketing team run them on the Managed plan.
- Table booking, guest marketing, reviews and your website come in the same system as your rooms, at one price per site.
- An AI team (Beta) working around the clock once you switch it on, and live chat with our marketing team on every plan.
- Vetted Marketing Experts on the Managed plan: a Certified Partner Agency (such as Founding Partner Mr Digital) runs your marketing for you, under a retainer contracted and invoiced by that partner.
Where Guestline is stronger
- Scale in hotels: Guestline says it serves more than 3,500 hoteliers.
- Self-service check-in kiosks, which mDOS doesn’t offer today.
- An established hotel EPoS and a revenue management system, where our till is still in Beta and our rates follow rules you set.
- Distribution through more than 2,000 global partners, and the backing of Access Hospitality.

Moving from Guestline at your own pace
Switch in phases, not all at once. Keep Guestline side by side while its contract runs out, start with guest marketing or your booking engine, and we move your guest history across. Your switching plan is built around your hotel.
More than a hotel system
Unlike Guestline, mDOS isn’t only a hotel system. You get The Platform, The AI Agents and The Marketing Experts, working as one, at one price per site.
World-leading software
Not just a hotel system: your website, bookings, customer records, marketing and team tools in one system.
Tireless AI agents
AI agents draft campaigns, review replies and follow-ups for you to approve, and spot problems early. Nothing goes out without your approval.
Real experts driving it
Vetted Marketing Experts, led by our Founding Partner Agency Mr Digital, set the plan and steer the AI. On Managed, we run your marketing and answer for the results.
