As answered by people managing React-Ionic and Axiom Booking.
Axiom Booking's answer:
Organisations that hire out space or run bookable sessions: offices and meeting rooms, coworking spaces, sports and leisure venues, studios, clinics and therapy rooms, training providers, and community centres and halls.
Day to day it's used by owners, facilities and centre managers, administrators and front-desk staff. Many are running bookings from a spreadsheet, a paper diary or an inbox, and losing hours every week to double-bookings, chasing unpaid invoices and answering the same availability question on the phone.
These are also the people who hold the building's paperwork, usually with no system behind it. Insurance certificates, safety policies, risk assessments and hire agreements sit in email or on a shared drive, and nobody is sure which copy is current. The document manager gives them one place to keep it, with every earlier version retained and dated.
Axiom Booking's answer:
It started with watching small venues try to run bookings on spreadsheets and paper diaries. Halls double-booked because two people wrote in the same slot. Invoices typed out by hand, then chased by hand. Staff on the phone half the morning answering "is Tuesday free?".
The software already out there didn't fit. It was built either for corporate meeting rooms or for gym class timetables, and almost all of it charged per user, which makes no sense when whoever takes the bookings changes with the rota.
So we built one system that handles both kinds of booking, takes care of the invoicing that follows, and lets customers book and pay for themselves. Staff accounts are unlimited, because the person on the desk on a Tuesday shouldn't be a line on the bill.
Axiom Booking's answer:
Most booking software handles either space hire or classes, so organisations that do both end up running two systems. Axiom Booking covers both. The space module handles rooms, desks, halls and venue hire; the session module handles classes, courses and one-to-one appointments. Use one, or use both together.
Invoicing is part of the same system. Bookings can raise their own invoices, and every payment is reconciled against a full transaction ledger, so your diary and your accounts stay in step.
You pay per bookable item, not per user. Staff accounts are unlimited, so growing your team doesn't increase the bill.
Axiom Booking's answer:
If you hire out rooms and run classes, most products make you choose one or pay for two systems. Axiom Booking does both, and it includes the invoicing, card payments and client records that scheduling-only tools leave you tracking in spreadsheets.
Your customers get a branded booking portal on its own web address, or embedded in the website you already have. They see live availability, book and pay without needing to phone or email you.
It is designed and tested to WCAG 2.2 Level AA, so staff and customers can use it by keyboard or screen reader. Our accessibility statement is on our website.
Pricing is £2 a month for each active space or session provider, not per user, so every member of staff can have their own account at no extra cost. Card payments carry a 1% platform fee, capped at 20p, plus Stripe's own fees, and SMS is pay-as-you-go.
Axiom Booking's answer:
Axiom Booking is built on .NET and Angular and runs on Microsoft Azure, with the database held in Microsoft's UK data centre and backed up automatically. Sign-in is handled by Microsoft Entra, Microsoft's own identity service, and card payments go through Stripe, so we never store card details ourselves.
