Custom software · Event companies

Build an event system around your costing sheet and your vendor list.

An event is planned in three weeks and paid for over three months. Advances leave fast. Client money arrives slowly, and the margin is only clear when the last vendor bill turns up.

By then nobody remembers the call where forty more guests were agreed. Or the two extra LED panels that went up on the night. Or the advance paid to the sound vendor for a different event in the same week.

Software for an event company has to hold all of that in one place. The costing sheet, the vendor bookings, the production plan, the crew, the run sheet and the settlement. Every client change gets priced and recorded as it happens.

The modules, and what each one covers.

The journey

One connected workflow, end to end.

  3. Costing
  4. Quotation
  5. Confirmation
  6. Production plan
  7. Vendor booking
  8. Crew deployment

  12. Vendor bills
  13. Settlement
Built in phases

You do not have to replace everything at once.

Each phase is usable on its own, so the system earns its place before the next part is built.

  1. 1

    Enquiry to quotation

    Enquiries, site visits, rate cards, the costing sheet and quotation versions. The margin becomes visible before the event is confirmed.

  2. 2

    Vendors and production

    Vendor bookings, advances, the production plan, own equipment and the event calendar that stops two events colliding.

  3. 3

    The day itself

    Crew deployment, tasks, the run sheet on every phone, guest management and the on-site record.

  4. 4

    Settlement and analysis

    Vendor bill matching, client invoicing with approved changes, collections, the client portal and the profit per event.

How we work

How a build actually runs.

  1. 01

    Understand

    We go through one finished event with you, from the first costing sheet to the vendor bill that arrived three weeks late.

  2. 02

    Map

    Event types, cost heads, vendor categories, crew roles, approval points and the moments where money leaves before it arrives.

  3. 03

    Design

    Screens for a planner at a desk in March and a supervisor at a venue at two in the morning.

  4. 04

    Build

    The costing sheet and vendor bookings first, because that is where the margin is lost.

  5. 05

    Test

    Your team runs a live event through it in parallel with the sheet they already use.

  6. 06

    Deploy

    Go-live between seasons where possible, with planners, production and accounts trained on their own screens.

  7. 07

    Improve

    Guest management, the client portal and the analytics, once the costing and settlement are running properly.

Common questions

Questions owners ask before starting.

What does custom event management software do?

It keeps the costing sheet, vendor bookings, production plan, crew, run sheet and settlement on one event record. The point is knowing the margin during the event rather than a month after it.

Can it show the margin while the quotation is still changing?

Yes. Each line carries your cost and the client price, so the margin moves as the client revises the headcount or the theme.

Can we track vendor advances properly?

Yes. Every advance is booked against a specific event and vendor, so three payments to one sound vendor in one week do not merge into a single confused balance.

Can the team see the run sheet on their phones?

Yes, and it updates once for everybody. That matters most on the day, when the event lead cannot answer his phone.

Can it record client changes and their cost?

Yes, with the date, the person who asked, the cost effect and the approval. It cannot make a client pay for a change he now denies asking for.

Can it manage our own sound and light stock?

Yes. What is committed, what is out, what came back damaged and what is available on a given date, which is the question that decides whether you take the second booking.

Can it handle conference registration and badges?

Yes. Guest lists, registration links, badges and check-in can be built in, or connected to a platform you already use where that platform allows it.

Will it help with permissions and licences?

It tracks applications, documents and deposits. Which permissions your event legally needs is for you and your lawyer to settle, and no authority works to a software timeline.

Do we need custom software, or will a product do?

Our event and wedding management software already covers enquiries, quotations, vendor bookings and settlements, and for many planners that is enough. Custom work suits production houses, rental fleets and unusual cost structures.

Can it work for both weddings and corporate events?

Yes, though the two want different screens. Weddings run on functions and families. Corporate events run on approvals, purchase orders and delegate counts.

Can freelancer crew payments be tracked?

Yes. Rates, call times, attendance on site, overtime and what has been paid, per event and per person.

Can we start small?

Yes. Costing, quotations and vendor bookings first. Guest management and the client portal are worth more once the money side is honest.

Your trade

How we work with this trade.

Already built

Software we already run for this work.

If one of these fits, it is cheaper and faster than building from scratch. We will say so.

Build a system that knows what the event cost you.

Every event company can tell you what an event was billed at. Far fewer can tell you, in the week after, what it actually cost once the last vendor bill and the night’s cash payments were counted.

Pick your last big event and try to say what it cost you. If that takes more than an afternoon of asking people, the costing sheet is the build, and everything else can follow it.
