Start with one specification for every supplier
Send each supplier the same list of exact phone models, quantity by model, number of artwork versions and intended destination. State which requirements are essential and which are questions. A quote for one design on one model cannot be compared directly with a quote split across several models and designs.
Ask each supplier to identify the proposed case blank and print area in writing. If a finish, magnetic feature, protective feature or packaging format matters, ask whether that specific option is available and included. Do not treat a product image or a retail listing as an approved business specification.
Useful comparison line: model + case option + artwork version + quantity + destination. Keep one line for each combination, then ask how setup or minimums apply across lines.
Compare the full project cost, not just the unit figure
Request an itemized quote that identifies any artwork setup, proof or sample charge, unit price, packaging, shipping and applicable taxes or fees. Ask whether quoted quantities are per model, per design or across the whole order. Then compare the total for the same scope. If a line is missing, mark it “not quoted” rather than assuming it is free.
A simple worksheet has columns for scope, included, excluded, needs confirmation and quoted amount. Use it for each offer. A lower unit price may still produce a higher project total when setup or delivery is added; the reverse can also be true. The comparison is only meaningful when the inputs match.
Agree on proof and change points
Ask what you will approve before production: a digital layout, a physical sample, or another agreed proof. Confirm who checks spelling, logo position and the camera opening for every phone model. Ask when a change to artwork, model mix or quantity would require a revised quote.
Color expectations deserve a separate conversation. A screen preview is not a guarantee of finished color, and this guide does not claim a particular tolerance or testing method. Get the supplier's actual process and any acceptance criteria in writing for your project.
Separate production time from delivery time
Give suppliers the date you need the goods and the delivery ZIP code, then request the estimated approval date, production window and shipping method as separate items. Ask what must happen before the schedule starts, including final artwork and payment. A requested arrival date is not a commitment until it is accepted in the quote or order terms.
If you need direct-to-customer fulfillment, special labeling or a recurring reorder process, request those terms separately. Do not assume a supplier's printing quote includes these services. For a U.S. printing claim, ask what operation occurs in the United States; printing location alone does not establish the origin of every case blank or component.
Choose the offer you can actually approve
- Reject comparisons with different model, material or quantity assumptions until clarified.
- Calculate the total for the same scope, noting every unquoted item.
- Confirm proof, change, payment and delivery terms in writing.
- Keep the approved specification with the final quote so both sides refer to the same version.
