I wonder if anyone can help. I am looking for a format for invoicing CDM-C services/duties.

I'm NOT looking for people's rates/figures, just an idea of how to quantify the duties in an invoice.
e.g. Do you just list the duties of the CDM-C and put a figure against each duty? Do you just to one big lump sum and do a percentage of it on a monthly basis? Do you simply put an hourly rate and invoice against hours worked? What's your method?

Any help gratefully received.

Hi NMC,

Sometimes if there is a framework contract, where there will be several projects, there will be a framework agreement in place that will assign an approximate value for the CDM-C service for each project depending on the construction costs for that project. this means that say the project construction costs would be 100k for arguments sake then the agreement would tell you that for projects ranging in value between 90k and 120k then perhaps the CDM-C service value would be 0.25% or 0.5% of the overall construction budget.

Generally the higher the construction value the lower the percentage, as the scope of the CDM-C service allegedly doesn't increase.
However, in my experience many of the framework agreements still being used were developed for the PS service and either way haven't evolved much in the last so many years so they could be based on a very tight, out-of date scope of service.

Other ways to calculate costs for CDM-C service are to break the CDM-C scope of service down into approximate hours considered for the specific project in mind for the service actions etc, then charge staff rates/overheads etc plus contingency.

Overall, depends on the company's scope of service and the client requirements (for example does he want the CDM-C to undertake site audits, attend every meeting, input to maintenance integration systems etc.

N,

I post a day rate, plus milage and hotel.

Day rate is £1 000, hotel is about £100 per night. Milage is about £1.

Do not go for the £25 per day rate. Remember that you have to make a profit and buy the car.

Or your wife goes for a divorce.

Last week I did 1 000 miles. 5 days away from home. No bills but two promises. Carol is still smiling. And I have (5 minutes ago) recieved a contract by e-mail. Even bigger smile. May be on a promise tonight ?

That's the way to do it !

N,

sorry for the former slighty frivolous seeming response (though actually real/real life)

your contract with your client should respect/refelect their job specification.

If they are a bit fuzzy in defining the job then you, too, can be a bit fuzzy in defining your commitments.

This sort of thing happens. They do not know what they want, so you do not know what they expect.

We do our best. Which is what qualiifies us as "consultants"

Charge heavy. But then you have to deliver.

If you are asking for £25 then they will only expect one risk assement.Charge them £1000 and they want 18000 qualification (mind you, that wold take at least 10 days)

Have I yet managed to boil your brain ? Does it even start to hurt ?

Hi NC

Not sure that the above responses answered your question. We generally charge a % of the total fee on a monthly or bi-monthly basis.

Hope this helps.

Or alternatively you can define stage payments where each payment is an agreed percentage of the engagement fee.

It really does depend on your relationship with the client and your ability to manage the invoice flow. If you look at legal practice the generality is to agree an overall fee projection and invoice monthly according to the hours input etc during the bill period. This does need good record keeping though.

In Merv's world and mine as an optimum point we prefer payment up front with no pressure to complete to a deadline - but there are not many of these around;-)

In the end it is about managing your cashflow and keeping the bank manager happy.
