@bertsmobile1 , when do you sleep? Australia must have like 36hrs in one day. LoL.
Seriously, what you do and how you do it, to get all that done in one day/night, makes me think you're very good at what you do.
Knowledge and experience cuts repair times way down.
I spend much of my time researching the specific problems, diagnosing and looking for something I just laid down.
At one time, I thought I wouldn't have to stock a lot of parts. One to two day delivery seemed fine. Until I get 4 or 5 pieces of equipment tore down. Then when parts come in, remembering what mower the parts were for.
I had a customer yesterday that wanted to buy blades for a 61" scag. I quoted him $90 for 6 (cash). He said to order them because he was paying the dealer $120 for 6. I told him I needed the $90 up front, he refused. Parts on hand means getting the sale and the job done right then and there.
That is why I keep a big inventory but not a lot of each item, usually just 2 sets of each blade that my customers use and a few more for those that my contract customers use.
Chain is always 200' rolls so I can price match, forget the premade loops .
When Jackmax lost the Carlton franchise they had a fire sale & I bought a roll of every size for 1/2 the normal wholesale price so they cost around 10¢ to 25¢ per DL
You forget I do not have a retail presence so If I work till 3 am I can sleep in till 10am .
The business name is Bert's MOBILE mower repairs so people usually ring first & I arrange a mutually beneficial time to do the transport.
Sunday is the big day for gate sales as the mower shops are all closed and most of the locals are city business people living the dream on acerage that they do not have the time to maintain.
Saturdays are not bad either as I get people calling in on their way home after the glass fronts did not have the parts in stock, and I do.
The other problem is low inventory at the warehouses.
Have a tension arm for a timecutter 36" on order for over a year , nill stock in OZ & nil stock in the USA . Briggs stator took 18 months & 12 months for a 31 series cam.
Just got rings for a FX651 that have been on order for 3 months , waiting for a rod for a CV18, again two months old and on it goes.
Ordered 10 belts last week, got 4 , 6 on BO so it is fit a bigger idler ( or two ) and a longer belt .
And like Star, 2 of each pulley size and when there is a minimum no delivery quantity then place the order.
So much easier to repair from stock than order replacements latter and in many cases the delivery cost can double the parts prices.
Also allows me to order from different wholesalers to get best prices ( or better parts ) .
Even better it confuses the tax man as parts orders are never directly corellate to work done that month .
Then there are trade packs, if a part can be ordered in a bulk pack then I do so again a better price.
Boxed $ 15 oil filters for parts sales and bulk $ 6.00 filters for service fitment. Same for fuel filters $ 4.50 individual pack & 75¢ in a 50 pack .
So buy in the 50 pack , charge $ 5 for one fitted & offer the customer a prepacked one with a $ 6.50 price tag on it for a spare, so they think they got a bargan.
Same with air filters , most of the common ones come in trade packs of between 10 & 50 usually at about 1/2 the single item price.
