With the invoicing program of Invoice Office you can easily prepare your quotes with your own logo and corporate identity. You can also choose the data shown on the quotation and arrange it according to your own wishes.

Beautiful quotation templates
In the invoicing program you also have several stylish quotation templates that you can use as the basis for your quotation design.

Cover & Accompanying letterFor optimal effect, use an additional, personalized quote letter and / or a beautiful cover page. Distinctive and effective!
An offer letter is an accompanying letter with your offer. Making a quotation in report form with the price proposal on page 1 is standard. You can distinguish yourself with an offer letter. This sets the right tone, introduces your proposal and makes your offer personal. After all, you are (usually) not alone in submitting a quotation. With the invoice software from Invoice Office, you increase your chance of winning a job.

With the billing software of Invoice Office you can send multiple attachments with your quotes. A clearly legible quotation is the reason why you include details such as product specifications, etc. in an appendix. It is also often customary to send your terms of delivery as quote attachments.

  • Extensive product specifications and product properties
  • Technical descriptions, drawings and models
  • Calculations and spreadsheets
  • Corporate Brochure and Folders

  • General terms and conditions, Sales conditions and Delivery conditions
