For an Interioplantscaper, there are no more chilling words than, "We’re thinking of going inhouse with our plant care".  Your heart drops three stories, your palms (not that kind, the other kind), go sweaty, and you stammer your dire warnings. 

May I suggest you take a deep breath and get your arguements together. 

• In House Plant Care works when it is for a large venue where the same staff cares for both interior and exterior.  Example:  Large Vegas Properties where the staff cares for Interior, Exterior, Floral, Events, Holiday etc.
• For regular corporate work it can be a nightmare.  The employee is treated like all other regular employees and receives all the benefits and other perks.  This may end up costing far more than an outside service.
• What is the in house persons capabilities?  They will be responsible for thousands of dollars worth of plants, live plants.  If the coporation is thinking of poaching one of your employees, let them know you have non compete agreements with all of them and that you will pursue any infraction.  (Then make sure you have npn-competes.

Also, make sure the contact person understands that the fee they pay you monthly is not just a labor charge.  Sometimes they do not understand the replacement factor which can be a third or, even, half   of your charge.  This cost will still go on only now it is out of their pocket on top of salary and benefits.

Then there are the anecdotal warnings.  Example:  A friend of mine had a one man plant care business.  One of his largest clients was thinking of going in house Feb. 1, possibly hiring my friend as their in house employee.  On Jan 2, he was removing a 6′ wreath from their exterior entry using a 12 foot ladder.  It was lightly snowing, he looked up, got disoriented, and fell ,shattering his leg.  He was off for three months and his workman’s comp went sky high.  The change to in house never happened and, in fact, the corporate contact was heard to say to a coworker, "Boy, what a nightmare.  Glad we didn’t hire him in house.  It would have cost us a fortune."  Meanwhile, a friend maintained the account for him for the three months he was off, he got ell and retained the account as an outside vendor.  And, they all live happily ever after.

So, take a deep breath and get your ducks in a row.  E mail other scapers you know and get their anecdotal stories as well.  Remember, the contact person wants to be a hero and not make mistakes that higher ups see.  Help him avoid doing so.  Now, go out there and get ‘em, Tigers and sell some TOPsiders and use those Joeys.
