A smooth custom project depends as much on what the buyer prepares as on what the factory does. When a buyer arrives with clear, complete materials, the design and sampling process runs quickly and with fewer rounds of revision. When the brief is vague, the project stalls while questions go back and forth, and extra time is spent guessing what the buyer actually wants.
This FAQ gives buyers a practical checklist of everything to prepare before starting a customization project with Zishine. From logo files and design references to dimensions, packaging, certification targets and order details, this is the brief that lets the engineering team quote accurately and move straight into work.
Q: What logo and branding files should I prepare?
Provide your logo in a vector format, such as AI or EPS, so it can be scaled cleanly and applied to small printing, laser engraving or packaging without losing quality. If you only have a raster image, use the highest-resolution version available and note the logo's colours, ideally as Pantone or CMYK references so the print matches your brand. Also specify where the logo should appear: on the front of the product, the back, the packaging, or all of these, and in what size. Clear branding assets remove guesswork and avoid the common problem of a low-resolution logo looking blurred on the final product.
Q: What design references or product direction should I bring?
Reference images, links to products you like, or simple sketches help communicate the look you want. Note which parts of the reference you want to keep and which you want to change. If you have target dimensions, a preferred shape, or a specific colour palette, include them. Even a rough description of the use case, such as a slim travel power bank or a rugged outdoor model, gives the design team a clear starting point. The more direction you provide, the fewer rounds of prototype review are needed, because the first design lands closer to your vision.
Q: Do I need to specify product dimensions or technical requirements?
It helps to share any target dimensions, capacity, output power and feature requirements you care about, such as wireless charging, specific ports, LED display or fast charging protocols. If you are not sure about the technical details, that is fine: describe the user scenario, and Zishine's engineers will propose the appropriate specifications. The important thing is to state the must-have features and the nice-to-have features separately, so the design prioritizes what matters. For a private-label project on an existing platform, confirming which features to keep or remove speeds up the proposal.
Q: What should I prepare for packaging design?
Tell Zishine whether you need retail packaging, a plain colour box, or custom printed packaging, and provide your packaging design files if you have them. Include the brand artwork, product images, specification text and any required regulatory markings for the target market. If you need multilingual user manuals or warranty cards, mention the languages. Also note whether the packaging must meet specific market requirements, because that affects what information and markings go on the box. Clear packaging requirements up front prevent the product from being ready while the box is still being designed, which would delay shipment.
Q: Which certification requirements should I state?
Tell Zishine the destination markets for your product, because they determine which certifications are needed. For Europe, CE marking is expected; for the United States, UL and related FCC considerations; for Japan, PSE; and for shipping lithium products, UN38.3 is standard. If you already have specific certification requirements from your retail channel or platform, share those documents. Stating the target market early means the product is designed and tested for the right standards from the start, rather than needing rework after a sample is built. This also affects cost and timeline, so it should be agreed at the planning stage.
Q: What order and commercial details should I prepare?
Provide your estimated order quantity, target price band, and the timeline you are working toward, including any launch events or sales seasons you need to hit. The quantity affects the choice between a private-label project on an existing platform and a fully custom ODM with new tooling, because tooling investment is justified by larger volumes. Knowing the target price band helps engineers propose a design that fits, rather than developing a product that exceeds your budget. A realistic timeline lets Zishine plan sampling, tooling and production accordingly and flag if a requested launch date is too tight.
Q: Should I prepare product photos or marketing materials?
If you have existing marketing copy, product images or a brand style guide, share them so the product and packaging align with your overall brand presentation. If you plan to sell on a specific platform, the platform's image and listing requirements can also guide what the product needs to show. While marketing materials are not required for engineering, they help Zishine understand your positioning and ensure the final product supports how you will sell it. For buyers who want content support, Zishine can advise on product photography angles and features worth highlighting based on the design.
Q: What if I only have a rough idea and not all these details?
That is completely normal, and many buyers start with only a rough concept. The key is to share what you know and let Zishine's engineering and account team help fill in the gaps. Describe the product you imagine, the market you target and the budget range, and the team will propose specifications, suggest a platform or custom design, and outline the next steps. You do not need to arrive with a complete engineering brief; you need a clear goal and an open line of communication. Zishine turns rough ideas into structured proposals, guiding you through the decisions rather than expecting you to know everything up front.
Q: How does preparing these materials speed up my project?
Complete materials shorten the whole cycle. When the logo files, design direction, packaging, certification targets and order details are ready at the start, the requirement review concludes quickly, the first prototype is built to your expectations, and fewer revision rounds are needed. The opposite situation, where materials arrive piecemeal, means the project pauses repeatedly to ask for missing files or clarify decisions. Spending a little time to gather everything before the first meeting pays back as faster sampling, faster tooling and an earlier delivery. It also produces a more accurate quote, because the engineers are pricing the actual product you want rather than a guess.
Q: What is the first step after I have prepared these materials?
Send your brief to Zishine's account team with the gathered materials attached. The team will review the requirements, confirm feasibility, and come back with a proposed product specification, a suggested development path between private label and full ODM, an estimated timeline and a commercial proposal. From there, the project moves into the requirement review and design stage described in the previous FAQ, with samples at each milestone for your approval. With 15-plus years of lithium battery experience, a 22,000 square metre Xiangyang production base and a Shenzhen R&D centre, Zishine is set up to turn a well-prepared brief into a finished, certified product for markets around the world.
