When a supplier does not turn up, call them rather than messaging, find out where they actually are, and set a firm time by which a replacement starts if they have not arrived. Then tell the client briefly, with the solution attached. The next working day, put what happened in writing.

That sequence only works if most of it was decided in advance. A planner who has backup names, contact numbers on the run sheet and a clear contract can make the call in minutes. A planner without those spends the time hoping, and the guests notice before the planner acts.

Prevention starts two weeks out

Most no-shows begin as something ordinary, such as a diary error, a wrong address or a misunderstanding about arrival time. The sheer number of suppliers makes those errors likely. The Knot Real Weddings vendor report found couples hired an average of 14 wedding professionals, and each one is a booking that can go wrong.

Written confirmation in the final fortnight surfaces those errors while there is still time to fix them, even with suppliers the planner has used many times. Send every supplier the run sheet about a week out and ask them to confirm their own lines. Our guide to writing an event run sheet covers how to make those lines clear enough to confirm.

A reply saying "we arrive at 4:00" when the sheet says 2:00 is a no-show caught early. Confirm the practical details as well as the time, and ask each supplier for four things.

  • The name of the person who is actually coming.
  • The vehicle they will drive and where it will park.
  • A mobile number that will be answered on the day, since an office line that goes to voicemail on a Saturday is no help at 5:00 pm.
  • The name of whoever they would send if their own person fell ill.

Know which suppliers the event depends on

Not every absence is an emergency. A missing florist is a disappointment, but a missing caterer means a room of hungry guests and a stalled evening. The table below sorts suppliers by impact, which tells the planner where a backup is essential and where improvising will do.

Table / 6 suppliersWhich absences stop an event and which do notArrange the fallback before the day, starting at the top
SupplierIf they do not appearFallback to arrange in advance
CatererGuests go unfed and the schedule stallsVenue kitchen or a second caterer on call
OfficiantThe ceremony cannot legally go aheadA backup officiant, confirmed free that day
Sound and MCSpeeches and cues cannot happenThe venue's house system and a named stand-in
PhotographerMoments are lost for goodA colleague the photographer can send
Florist or stylistThe room looks unfinishedThe planner's kit and the venue's linens
CakeA gap in the scheduleDessert from the caterer

The top rows deserve two backup names each, with numbers saved on the run sheet itself. The lower rows can usually be handled on the spot with the planner's own kit and some quiet improvising that most guests never notice.

Ask about backups when booking, too. Many photographers, bands and caterers have their own arrangements for illness or a broken-down van, and knowing who they would send saves a search on the day. A supplier with no plan at all is worth knowing about before the contract is signed.

Public safety agencies think about large events the same way, ranking hazards by impact before the day. FEMA's special events contingency planning course applies that at city scale. A private event needs a far lighter version, but the habit of deciding the fallback in advance is the same.

The first fifteen minutes

When a supplier's arrival window passes with no sign of them, the clock matters more than the cause. The sequence below keeps the planner acting rather than waiting, and each step feeds the next decision.

Sequence / 5 stepsWhat to do once an arrival window has passedEach step sets up the decision in the one after it
  1. 1

    Call, do not message

    Ring the supplier and their office. Ask where they are right now, not whether they are coming.

    Hands on a real location and arrival time
  2. 2

    Set a replace-by time

    Work back from when the service is needed. If they are not there by then, replacement begins.

    Hands on one deadline everybody knows
  3. 3

    Start the backup quietly

    Call the backup before the deadline so they are ready to leave if needed.

    Hands on a replacement on standby
  4. 4

    Tell the client, with the fix

    A short, calm message at a natural pause, never mid-ceremony or mid-speech.

    Hands on a client who heard it from the planner first
  5. 5

    Adjust the run sheet

    Move the lines that depended on the missing supplier, and tell their owners.

The worst version is the planner who spends forty minutes being reassured by text and delivers the news when nothing can be done. A replace-by time removes that temptation, because the decision was made before anyone felt awkward about making it.

Step five is easy to forget under pressure. A late caterer pushes back the first course, which pushes back the speeches, which changes when the band starts. Telling the MC and the band about the new times keeps one problem from becoming three.

Telling the client

Clients handle problems far better than they handle finding out later that something was hidden. So tell them, but choose the moment and keep it short. "The band is running an hour late, so the venue's DJ will cover the first set" gives the problem and the answer in one breath.

Not every problem needs raising on the day. If a backup has already covered the gap and the guests cannot tell, a planner can reasonably wait until the next morning. The test is whether the client would feel misled on learning about it later.

The planner should be the one who tells the client, not the supplier or the venue. A late photographer who messages the couple directly, full of apologies, turns a manageable delay into a worry. Asking every supplier to route problems through the planner is worth a line in each confirmation email.

Having a planner on site at all is what makes that possible. In our experience at the Event Planning Institute, about two in three of the supplier no-show stories we hear come from weddings where nobody was employed to coordinate the day. Without that person, the couple or a relative ends up making the calls.

After the event

Write to the supplier the next working day, while the facts are fresh. State what was booked, when they arrived or failed to, and what it cost to cover. A factual record matters if a refund or a dispute follows.

Then check who holds the contract, because that decides who carries the loss. There are three possibilities.

  • The client signed. The claim against the supplier belongs to the client. The planner helps document what happened but is not the party owed a refund.
  • The planner signed. The claim belongs to the planner, who may also owe the client under the planner's own contract. The planner carries the risk.
  • Nothing is in writing. Recovering money is much harder, and the real fix is a written booking for every supplier on the next event.

A planner unsure which case applies has found the thing to fix before the next booking. The event planner contract template shows how to state supplier responsibility clearly in the planner's own agreement with the client.

Whether to book that supplier again

One late arrival is not always a reason to drop a supplier. A florist stuck behind a highway accident who called ahead, sent a colleague and apologized has handled it well. A supplier who went silent, arrived without explanation or disputes the record is a different case, and the planner's own reputation rides on that choice next time.

Either way, record what happened on the planner's supplier list. Over a few seasons, those notes show which names are dependable under pressure, and that is the list worth offering to clients.

Where the course goes further

Unit 4 of the Fundamentals Course, Timelines, Logistics and Run Sheets, covers planning the contingency for weather, a late supplier and a no-show, alongside the run sheet itself. Unit 2 covers the service agreement and cancellation terms that decide who carries a loss. The Fast Track Course adds Unit 8, which covers managing a supplier who is late, wrong or under-delivering on the day.
