Codeeo delivers event management booking website development London organisers, venue teams and corporate event agencies use to sell places, take deposits and settle balances online. Delegates, hosts and procurement teams book against live availability, pay by card, wallet or invoice, and receive confirmations that match your terms. Your staff stop chasing payments by email and work from one calendar that shows who has booked, who has paid and what is still owed.
Our team is based in Dubai, Riyadh and Karachi and works with London clients remotely, with discovery, design reviews and testing sessions held over video call. We have delivered 200+ projects across the UAE and the US.

What the booking platform includes
Selling an event in London rarely means one ticket type at one price. A conference sells early and standard delegate places, exhibitor stands and sponsor packages. A venue sells room hire by the half day, catering per head and late licence extensions. An agency books a summer party on behalf of a client whose finance team wants a purchase order before anything is charged.
The event management online booking system development London clients ask us for has to handle that mix, and ours does. Availability is held in one place, so a meeting room, a riverside terrace or a breakout slot cannot be sold twice. Deposits, staged payments and final balances follow rules you set. Cancellations and refunds follow your written terms, and every change leaves a record your accounts team can trust. Below are the parts we usually put together, ordered by how often London clients ask for them.
One calendar for every space, session and package, with buffers for setup and get-out, holds that expire automatically and clear rules for provisional and confirmed bookings. Staff see the same picture as customers, so a hold placed for a City client in the morning cannot be resold by lunchtime.
No double bookings and fewer phone calls to check what is free.
Take a deposit at booking, a second payment at a set point and the balance before the event, with automatic payment links and reminders. Rules can differ for private hire, corporate clients and delegate places, and every payment is matched to the booking it belongs to.
Cash collected on schedule without staff chasing each instalment.
Corporate buyers in London often cannot pay by card. The checkout can accept a purchase order number, issue a VAT invoice with your registration details and hold the booking until payment arrives, while individual delegates still pay by card or wallet.
Corporate sales close without manual invoicing in a spreadsheet.
A booker can reserve twenty places, pay once and add names later, or send each colleague a link to complete their own details, dietary needs and access requirements before the deadline.
Group bookings stop arriving as one email with a list of names attached.
Your terms are built into the booking flow: what is refundable, when a deposit is kept, whether a place can be transferred to a colleague and how credit notes are issued. Refunds go back through the original payment method and the record shows who approved them.
Fewer disputes because the rules were clear at the point of sale.
Automated emails for unpaid balances, missing delegate names, joining instructions and venue access details, with travel notes for venues such as those near the Elizabeth line or the river. Marketing messages are sent only to people who agreed to receive them.
Guests arrive prepared and balances are settled before the doors open.
Assign event managers, AV technicians, hosts and caterers to each booking, see who is working where, and print or share run sheets. When a booking moves date, the people attached to it move with it.
The operations team works from the same booking record as sales.
Payments run through a regulated gateway with 3D Secure handled correctly, so UK and European cardholders pass authentication and card details never touch your own server. Saved cards for later balances are set up with the right customer consent.
Fewer failed payments and a smaller security burden on your business.
Bookings by space, event and channel, deposits held, balances due and refunds issued, exportable to your accounting system. Directors can see forward revenue for the next quarter without asking anyone to build a report.
Clear figures on what is booked, paid and still owed.
Who this is for
The common thread is money changing hands before the event happens. If your team currently confirms bookings by email, takes deposits by bank transfer and tracks balances in a spreadsheet, a booking platform pays for itself in time saved and payments no longer missed. These are the situations we see most often from London clients.
Organisers running professional events at venues such as the QEII Centre, Olympia or hotels in the West End need delegate registration, early and standard rates, member pricing and invoices for employers. We build registration that handles individual and group bookings, collects the details your badges and catering need, and keeps a clean list of who has paid. Changes to speakers or sessions can be published without breaking existing bookings.
Delegate data stays in your own system, not a rented platform.
Rooftops, galleries, livery halls, warehouses in east London and riverside spaces all sell hire by date and time, often with minimum spends and catering packages. The booking site shows real availability, lets enquirers place a short hold, and converts the hold into a confirmed booking when the deposit is paid. Your events team keeps control of approvals for larger or unusual requests, such as late finishes, amplified music or exclusive use, and the site can collect the details your licensing conditions require before a booking is confirmed.
Agencies plan summer parties, awards dinners and offsites for clients across the City, Canary Wharf and beyond. They need client portals where each account sees its own events, approves quotes, pays staged invoices and shares guest lists. We build that around your existing workflow, so account managers spend less time copying figures between quotes, invoices and supplier bookings. Supplier costs and margins stay visible only to your own staff, never to the client looking at the same event.
Smaller operators selling cookery classes, tastings, tours or creative workshops across London boroughs need a fast mobile checkout, gift vouchers, waitlists and simple rescheduling. Because these are leisure services for a specific date, your cancellation terms carry more weight than a statutory cooling off period, so we make sure customers see them before paying.
Clear terms reduce chargebacks and awkward refund conversations.
How we work together
We do not have a London office, and we do not pretend otherwise. Every workshop, design review and acceptance test runs over video call, with shared documents that record what was agreed. You get one project lead who knows your booking rules in detail, plus designers, developers and testers from our team of 80+ across Dubai, Riyadh and Karachi. What drives cost and timeline is the number of products you sell, how complex your payment and refund rules are, how many systems the platform must talk to and how much of your existing data needs to move across. We price after discovery, once those things are clear.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
We choose the stack around your team and integrations: commonly Next.js or Laravel for the booking platform, a payment gateway such as Stripe or another FCA authorised provider, and connections to tools such as HubSpot, Xero or Microsoft Dynamics. Everything is hosted in accounts you own.

Scope, payment rules and integrations matter far more than the number of pages.
A booking site for one venue with a single deposit rule is a very different build from a conference platform with member pricing, group bookings, purchase orders and exhibitor packages. The main cost drivers are the number of bookable products, the complexity of deposit, refund and transfer rules, the systems we connect to, such as your CRM and accounts package, and any data migration from an existing ticketing or booking tool. Design depth and the number of user roles in the admin area also play a part. We give a fixed proposal once discovery has written those down, so you know the scope before any build work begins.
