What Suppliers Are Really Asking For When They Want Your Timings

Everything here earned its place by changing an outcome. Nothing about the timeline suppliers keep asking for is included to round the number up.

Why the question keeps coming back

Suppliers ask for timings repeatedly because their own planning cannot start until they know how many hours they are covering and in what shape. A caterer decides staff numbers, a photographer decides whether a second shooter is needed, and a band decides when to load in, all from the same document.

When it does not arrive, they build a plausible assumption, and the assumption is usually generous to them and inconvenient to you. The gap between your imagined day and their assumed day is invisible until it appears as an extra charge or a supplier packing up early. Sending an imperfect timeline early is far more useful than sending a perfect one late.

What a photographer is calculating

Light is the constraint that couples underestimate, and a photographer is working out where the sun will be relative to your ceremony and your group photographs. They are also counting the group shots, because each configuration takes minutes to assemble and a long list can quietly consume an hour of your reception. Coverage hours are the commercial part, and knowing whether they finish after the first dance or after the last guest changes the quote.

Once the deposit is paid, if they arrive without knowing the plan they will follow it as it happens, which produces a record of the day rather than a considered one. Telling them what you want photographed matters more than telling them what style you like.

What caterers need from the timings

Kitchens work backwards from a service time and cannot easily absorb a delay, because food that is ready has to be served or degraded. A thirty-minute overrun on speeches is not a thirty-minute delay to the meal; it can force a rushed service or a course dropped in quality.

Between the two families, whether speeches come before or after the meal is therefore a catering decision as much as a social one, and caterers have firm opinions worth hearing. Staffing levels are set from guest numbers and service style, so a change from plated service to sharing plates is not a small amendment. The final numbers deadline exists because food is ordered against it, and after that point the count usually cannot come down.

What everyone else is working out

Florists need to know when the room can be accessed and when it changes use, because a ceremony room that becomes a dining room needs a turnaround team. Bands and DJs need load-in access, power, curfew and the length of the sets, and a curfew discovered late can shorten the evening you paid for. Transport providers need the pickup points and realistic journey times, and a coach that has to do two runs changes the whole afternoon.

Hire companies need collection windows, which are frequently the morning after and therefore need someone present who is not you. Every one of these is cheap to answer in advance and expensive to resolve on the day.

The cost of a late timeline

Once a supplier has staffed a shift, changing it means either paying for people who are no longer needed or failing to find people at short notice. Overtime rates exist because the venue and the crew are contracted for a period, and extending it involves other people's contracts too.

Late timelines also push all the confirmation work into your final fortnight, which is the period you most need to be free. Suppliers who receive plans early tend to give better advice, because they have time to notice the problem rather than react to it. The timeline is the single document that most reduces what a wedding costs in stress, if not in money.

How to send it

Send one document to everyone rather than tailored messages, so nobody is working from a version that only they received. Date it clearly and say plainly that it supersedes anything sent before, because superseded plans circulate for months otherwise. Name the person who will be making decisions on the day and give their number, and make sure it is not either of you.

Six months out, invite corrections explicitly, since suppliers frequently spot an impossibility that you cannot see from inside the plan. Then send a final version a fortnight out and stop, because a document that keeps changing stops being read.

The takeaway

Send the timeline early and imperfect, and the corrections will arrive while they are still cheap.

Decide early, decide once, and stop reopening it.
