"Organize it ourselves to save money" is a common reason many companies decide against hiring a professional organizer for team building, handing the whole job to HR or admin to figure out. On paper, the direct spend may be lower, but that is usually only half of the real cost picture.
The cost of time is the easiest to miss
Even a simple mid-size team building day still needs a long list of tasks: finding a venue, comparing prices, negotiating, scripting the program, preparing supplies, handling last-minute extras. For a company organizing it itself, this whole workload usually lands on one or two people in HR, taking up many working days that should have gone to their own specialist work. The biggest of the hidden costs of organizing team building is exactly this time, even though it appears on no invoice.
Risk from inexperience in handling situations
A professional organizer has been through many events and has backup plans ready for common situations: bad weather, late guests, equipment failures. An internal team organizing for the first time usually lacks this experience, easily gets flustered when something goes wrong, and sometimes pays far more for emergency handling than the market rate because it has no ready relationship with suppliers to negotiate quickly.
Three extra costs that commonly appear when organizing yourself
First, the cost of ordering services past the deadline: not knowing the milestones for early ordering to get a good price, you end up ordering close to the date at a higher rate. Second, the cost of fixing mistakes from inexperience in evaluating suppliers: choosing a provider whose service quality isn't as promised and having to find a replacement in a hurry. Third, the opportunity cost of HR being unable to finish its daily work while concentrating on organizing the event, leading to a backlog of pressure afterward.
When organizing yourself still makes sense
Hiring a professional organizer is not always the better choice. For a small group and a simple activity, like a get-together at a familiar restaurant or a picnic near the office, organizing it yourself still makes sense if the company has someone with experience and doesn't need special equipment or a special venue. The boundary to weigh is the complexity of the activity: the more specialized equipment is needed and the more operating safety skills are required (like kart racing), the more you should prefer a professional organizer over figuring it out yourself.
How to calculate it properly to compare the two options
For a fair comparison between organizing yourself and hiring an all-inclusive package, add both the direct costs and an estimate of the value of the staff time spent, instead of looking only at the figure on the organizer's quote. Multiplying the expected working days by the responsible person's average hourly pay gives a real number that can be added straight in to compare with the all-inclusive quote. Many companies that calculate it this way find the cost gap between the two options is much narrower than they first imagined.
A middle option: hire part, do part yourself
Between organizing entirely yourself and hiring everything, there is a middle option worth considering: hire a professional organizer for the main activity that requires technical skill and safety, for example the kart racing, while taking on simpler parts yourself such as preparing internal gifts or hosting a side segment. This saves the company part of the cost without carrying the risk of running parts that need real technical expertise.
Count the full cost of time and the risk of extras, not just the direct spend. Organizing it yourself is not always cheaper than hiring a professional organizer.
