There are alternative billing processes that are employed by Interior Design Firms to charge their clients for Interior Design Services rendered. During the initial interview with a prospective customer, a qualified Professional Interior Designer must give them the various selections available. This will help a customer choose on which kind of payment that will be preferred by them. Depending on the services required, the customer should be made aware that the selections open for choice is completely up to them after the qualified interior designer has listed it all out and explained every selection in great detail. So depending on the processes picked, both parties, that is the customer and the interior design expert will then come to an agreement on the best billing selection and whichever agreement is reached, it must definitely be acceptable to both parties involved. One thing for sure is that a client will get a good service from a qualified interior design expert who feels fairly compensated for the service that are to be rendered.

The billing processes that Interior Design Firms use for Interior Design Services are normally quite varied and they are as follows: pre-fixed rate for the whole interior design campaign, hourly rates for time served on the project, percentage for costs of materials and costs per square foot of the room.

This fixed rate is normally supposed to cover all contingencies and on agreement and a part of this fee is normally paid in advance before the work starts. The normal amount paid initially may range between 15% and 35%, though this payment is different from a deposit. A retainer is a certain amount of revenue paid to a qualified Professional Interior Designer to reserve their time to work on a project. However, whatever the case may be then it will invariably be treated as a form of deposit. And it must be spelled out in the letter of agreement that needs to be drawn up by a qualified interior design professional.

A popular mode of payments that is the hourly rate payment process has been used over the years by many professions such as architects, engineers, therapists, lawyers and accountants. It is well used by qualified Interior Design Firms too. The way it works is that a qualified interior design professional is supposed to keep detailed records of daily work and the amount of hours spent to execute the work. At the end of each month the customer is billed as per the number of hours executed. This mode of payment is actually for time but not necessarily a payment for the skills of a qualified Professional Interior Designer. Clients are a bit wary of this billing process simply because there may be instances where the interior designer may work slower than others. What will happen if the interior designer is slow or fast? It poses several problems and s[pin]customers|consumers|clients[/spin] sometimes feel they may be cheated but have no way to ascertain such fears as this is expected.

The percentage cost for materials is a process that is great for residential strategies, although it may be used for commercial strategies as well. Charges are the net or wholesale prices that the qualified interior designer pays to the merchants and then a predetermined percentage mark up is applied to the net price. The mark up is usually on the furniture and labor incurred whilst working on a client’s project. The actual net price is paid to the interior designer plus a commission which is inclusive of design and planning, delivery and installations but will not involve the cost for the Interior Design Services that the interior design professional performs on top.

Costs per square foot of the area is a very easy way of charging that is commonly used for area planning tasks and is usually a small amount per footage. What it entails is the qualified interior designer simply measures the client’s room to determine the square footage to be designed and then multiply by a pre determined and mutually agreed number. Room planning is a specialized aspect of interior design and involves the design of room allocation so that designated tasks and duties can be performed optimally, with added convenience, efficiency and comfort.
