Shape it to how you work, and let it handle the routine for you.

Run an offer brand-wide or at chosen sites, and limit it to tagged customers such as members.

The best live offer is applied at checkout and every rule is checked again before payment.

Offer a cake or a bottle at checkout, and see the take-up and revenue for each.
Offers that work wherever your customers book or buy.
Promo codes and rules are built in, so you don’t need a separate promotions engine.
One list of every offer and code, with dates and rules, instead of scattered notes.
Rules checked at checkout stop codes being used where they shouldn’t, protecting your margin.
YOUR AI TEAM, ON OFFERS
It works around the clock once you switch it on. Nothing goes out without your approval.
Flags codes given to people who would have bought anyway, and codes that ran out, and says which to fix first.
Checks live offers still have clear terms and flags any that ran past their end date.
For hotels, finds nights well behind last year and drafts a short-stay offer for you to approve.
Set up by real people, supported by AI. An mDOS Expert Partner sets up your first offers with you and is a call away, while the AI team checks they’re working and you approve every new offer it drafts.
Move one offer or one site at a time, and keep your current tools while their contracts run out. We bring your live codes across so customers’ codes keep working, and agree a tailored switching plan with you.
A promo code is easy to make. mDOS also gives you AI agents that keep offers honest and marketers who choose the ones worth running.

Create timed offers and promo codes once, choose which sites they apply to and let checkout apply the right one, so codes can’t be stretched.

AI agents flag codes that leak margin, check live offers still have clear terms and, for hotels, draft a short-stay offer for quiet nights.

An mDOS Expert Partner sets up your first offers with you, and partner marketers plan which offers to run and where to promote them.
