Six weeks after the gala dinner
The event was a success. The client sent a thank-you email. Your team is now three events further on. In the accounts inbox, supplier invoices for the gala dinner are still arriving: the caterer's final bill with extra covers, the AV company with an overtime line, the coach company with a waiting time charge, the florist who invoiced twice, and the venue's final bill with a room hire extension nobody remembers approving.
Your finance manager emails the producer to ask about each one. The producer is on site at a different event and replies late, from memory. The client's final invoice cannot go out until everything is checked, so the client's finance team starts asking why, and the event's margin stays unknown for months.
Why events do not close cleanly
Every invoice is checked against the question "is this right?", and the answer lives in the head of someone who has moved on to another event.
- Supplier invoices arrive at different times, some long after the event.
- Final invoices rarely match the quote because of on-site changes, numbers and extended hours.
- The approvals for those changes are scattered across calls, texts and emails.
- Nobody has a list of which suppliers have still to invoice, so the event cannot be declared closed.
- The final client invoice waits for all of it, which delays your own cash.
The price of a slow close-off
Slow close-off costs money in three ways. Invoices that are wrong get paid because checking them is too hard. Costs that should be recharged to the client are missed because the final client invoice was sent before they arrived. And cash is tied up, because your client pays you later than it should, while your suppliers expect to be paid on their terms.
It also hides the truth about which events make money. If margins are only known months later, pricing decisions for the next proposal are made without them.
A close-off view for every event
- Every supplier booking for the event is listed with its confirmed quote and any approved changes, from your quote and change records.
- Supplier invoices are read from your accounts package, such as Xero or QuickBooks, or from the accounts inbox, and matched to the booking by supplier and event reference.
- Each invoice line is compared with what was booked and approved, and differences are highlighted: extra covers, overtime, items never agreed, possible duplicates.
- Differences go to the producer as a short list to answer from a phone, with the evidence on screen: the change log, the on-site notes, the final numbers from check-in.
- The view shows which suppliers have still to invoice, and sends a polite request to those who are late.
- Rechargeable costs are collected into the final client invoice draft, with each line traceable to an approval.
- When every booking is invoiced and every difference is resolved, the event is marked closed and its margin is final.
| Supplier | Quoted and approved | Invoiced | Status |
|---|---|---|---|
| Caterer | Quote plus approved extra covers | Matches | Ready to pay |
| AV company | Quote | Quote plus overtime | Query sent to producer |
| Florist | Quote | Invoiced twice | Possible duplicate held |
| Coach company | Quote | Not yet received | Request sent |
Closing an event in normal working weeks
The producer gets a short list of queries on their phone while on site at the next job, each with the evidence attached, and answers them in a few minutes. The finance manager sees one screen per event with what is matched, what is queried and what is still due. The client's final invoice goes out once the rechargeable costs are in, rather than whenever someone finds time. Directors see real margins soon after each event, not at year end.
Does closing events look like this for you?
- Supplier invoices for an event arrive for weeks and are checked one by one against email.
- Final supplier invoices rarely match quotes and the reasons are hard to find.
- You cannot say which suppliers have still to invoice.
- Client final invoices are held up by late supplier bills.
- You only learn an event's real margin months later.
