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 ..
I'm with johnnyb in that if you're not marking up your materials you're passing them on to your clients at a loss. Even if you don't go out and collect the materials yourself and only spend time getting prices and ordering them for delivery you're investing your time and experience which has to be worth something.
I've always worked on the basis of applying 100% mark up for rough sawn solid wood, 50% mark up for board materials and 20% mark up for proprietary stuff, e.g., polish, hardware, abrasives, and other sundries. I'm semi-retired now so worrying about being competitive and making a profit isn't high on my list of priorities but, for example, if buying rough sawn solid wood cost me £500 it was resold to the client at £1000. The mark up was/is to cover sourcing and pricing, picking and collection, transport, labour, storage, etc. Even if I simply ordered wood and the supplier picked the boards and delivered I applied the same 100% mark up: that was simply to keep estimating or pricing simple, fair or not to my client.
On a side note, if a client insisted, against my advice, on supplying their own materials, particularly rough sawn hardwood, I frequently found there were good reasons to reject it, e.g., inferior quality, wrong sizes, and so on. That meant the client had to go through the whole return and buying thing again, which did tend to upset them, but that was the risk they'd taken on. And if the stuff a customer bought was suitable there's still the question of storage and handling at my end and I could always somehow find a way to charge for this service through, for example, bumping up other charges somewhere else, e.g., in the labour.
