I think it's crazy to allow the client to pay for the materials. If any business bought and sold everything for cost price, they wouldn't be in business for very long. I source my materials and sit down work everything out and recommend suitable materials from experience. The materials are always marked up but not a ridiculous amount.I imagine ( to echo the above post) that this thread has been useful to many members inc myself. What I’ve realised is my customers pay for the materials upfront wether they pay themselves or send me the money to pay on their behalf. I charge them the labour per day but I’ve picked up from this thread that I’m not charging for consumables ( plugs, screw , glue , nails etc) so I’m going to start factoring in 10 or 15 % to cover this cost . As a rule I don’t add anything to the materials so the cust gets the benefit of any discount from the supplier but I do make them aware of this . So yes as above a good thread ..
Work out the cost of the materials and the amount of time it will take you to complete the install/job and + atleast 20% or more (depending on budget and client) to the overall figure. This will give you a markup and allow for any unforseen time.
A business should be running wit a 30/40% profit mark up, but most are only running with like a 10/15% mark up. This is very close if there is a mistake or an unexpected delay or whatever.
You also need to charge for your consumables, it doesn't have to be crazy amounts. But it still costs you to replace, order, pick up, sort, store. If you're on a large install and use dominos/lamellos then these will have to be accounted for as they cost money to replace.
You can be nice and think oh well it's only a few boxes of screws and abit of glue I used for this install and that install, but when you come to replace them time and time again. It definitely adds up and it's your money your spending for someone else to benefit?
