Sahara Health.

Walk into an outpatient clinic in the Gulf at ten in the morning and the bottleneck is never the medical record. It is the twenty people in the waiting room, some of whom booked online, some of whom walked in, all of whom want to know how long this is going to take.

Before Sahara, that was a paper token roll and a receptionist shouting a number. Which patient is currently with the doctor, who is next, and how many are still waiting existed in one person's head, and left the building when they went to lunch.

Registration assigns an MR number and captures what the clinic is actually required to hold: full name, Emirates ID, date of birth, gender, address, and an optional patient photo. Most of it can be filled in later — what cannot wait is the phone number, because that is how the patient will be found again.

A clinic adopting Sahara has years of existing records under its old numbering — a serial from a paper ledger, or an MR from the system it is leaving. The registration form carries a Legacy MR / Serial No. field for exactly that, so an old chart number stays searchable after the switch instead of becoming a number nobody can resolve.

It is a small field doing unglamorous work. It is also the difference between a clinic that can migrate and a clinic that quietly keeps the old system running alongside the new one.

The OPD queue console is the screen the clinic leaves open all day. It shows the token currently being called, how many are booked, how many are waiting, and the split between patients who booked online and patients who walked in.

Calling the next patient is one action. So is going back, which sounds trivial until you have watched a receptionist advance the queue past someone who stepped out to take a call.

Walk-ins are issued a token from the same console, with the next number shown before it is issued, so the desk can tell someone what they are getting before committing to it.

A doctor's availability is usually a sentence: four till seven, Sunday to Thursday, fifteen minutes each. Making a receptionist enter that as individual slots is how clinics end up with half a calendar filled in and the rest missing.

The scheduler takes the date range, the time window and the interval, and generates the grid. Individual slots can then be locked, deleted, or booked against, and a day's slots can be cleared in one action when the doctor cancels a session.

Billing starts where the visit ended: find the patient, by MR number, by name or phone, or off the list of who has just been seen. That ordering matters. An invoice flow that starts with a blank form and asks for a patient last is an invoice flow that gets abandoned when the queue is six deep.

The invoice builder handles multiple line items with quantities and per-line discounts, multiple payment rows against a single invoice, and tax presets applied on top. Payment modes are the ones a Gulf clinic actually takes, cash included, with a transaction or cheque reference where one exists.

Part-payment is a first-class state rather than an edge case: an invoice can be issued, partly settled, and carry a running balance, which is what happens in practice when a patient pays some now and the rest on the next visit.

Sahara runs the operational day of a clinic. A patient is registered once and found by phone number afterwards. A queue has a state the whole desk can see. A doctor's availability is generated from a rule instead of typed. A visit becomes an invoice, and the invoice can be part-settled in cash without leaving the screen.

The platform is tenanted per clinic and per doctor, which is what makes the booking links work and what the next clinic onboards into.
