Our Process

Our design process follows a proven approach. We begin with a deep understanding of your needs and create a planning template.

Before we even give the customer a quote for the project, we need to gather all necessary requirements to see what it will take to complete the project, then we can offer a rough estimate and timeframe for the project.

Once our team has gathered all the requirements and needs from the customer, our project managers then create a design document to present the functionality, technologies, resources, and timeframes involved to complete the project. Once this is done, we send it to the customer for confirmation, and then send the contract for the company/business/individual to sign.

Once we receive the contract, our development process begins. Throughout this whole phase, we present a demo to the customer to show progress of the project. Our front and back-end designers/developers begin implementation following directions from the design document. During implementation, first there is front-end design, then development on the back-end, and then a final demo to the customer for approval.

After the implementation of the project is done, our testers begin fixing any bugs/issues with both the front and back-end of the project. In addition, they are configuring the project to all web browsers and mobile devices, depending on the project being built.

Once testing is completed, we present the website, software, or application one last time to the customer for approval, and then launch the product for public or personal use. Then we discuss hosting and maintenance options with the customer.

Frequently Asked Questions

  • What's the ideal profile of a partner agency?
    The ideal match is either a) An agency focused on retainer-based inbound marketing work and delivers already outstanding value for their clients, have strong relationships, and are perceived as trusted partners by their clients, but that do not have web design & development skills in-house. Or b) A larger agency that has web design & development skills but needs an overflow team to back them up.
  • Are the templates fully functional?
    We will play the front-end role of crafting beautiful designs by understanding end customer’s needs. eSparkBiz will work as a backbone to convert these designs into the awesome landing page, email, or website templates.

  • How does bug-fixing work?
    Throughout the development process, our QA Engineers provide extra oversight to ensure a quality product is delivered back to you. Before delivery, you will also get a chance to review the site on our feedback server and we will correct any deviations from the project brief at no additional cost. If you have additional requests at this stage, we will do our best to fit it into our development schedule and reserve the right to re-quote it if we estimate it to take more than a couple of hours to fix. After you have agreed that the site is ready and we have delivered it to you, we offer a 90-days free bug-fixing.
  • What design file formats can you work with?
    In order to provide you with a quote, it’s enough to send us jpg or png files, but you can of course also send us a Photoshop Design (PSD), AI or Sketch files. Before the start of development, we prefer to get layered Photoshop, AI or Sketch files for each page template to make the development process as efficient as possible.
