Every plan makes the whole pack.
Choose how many you need each month.
Every paid plan drafts all seven sections of the pack in full. What changes between plans is how many tech packs you generate each month.
Start free with one full tech pack and no card. Export unlocks on any paid plan.
Prices are monthly, in pounds sterling, and include any VAT due for consumers. Payment is taken by Stripe. Plan credits are issued at each renewal and last two billing periods, so an unused month rolls over once and then expires. Top-up credits last twelve months.

What a credit buys
A full tech pack is 10 credits. Smaller jobs cost less, so you are not paying pack prices for a colourway or a single redraw. Exports, manual edits, viewing, sharing and version history are always free, and every charged pack includes two free redraws. A credit is used when a pack is generated, whether or not it passes the factory readiness gate, because the run costs the same either way. Cancel before a run finishes and the credits go straight back.
Factory
430 credits a month, which is 43 full tech packs. Everything in Atelier, for teams shipping a range rather than a capsule.
Top-ups
For the month that runs short. Top-up credits are priced above the subscription rate, because a subscription is a commitment and should be the cheaper way to buy. Top-up credits last a year.
THE SEAMIX
FULL TECH SUITE.
Available in All Plans. Every Seamix subscription grants you unrestricted access to our end-to-end synthesis engine. We don’t hide our best tools behind higher price tags—we give you the full arsenal to build your brand from day one.

Illustrative estimate only. The struck-through figure uses £80 per tech pack, which is the median of 23 fixed-price tech pack offers listed on PeoplePerHour on 5 September 2026, where prices ranged from £15 to £655. The Seamix figure is the cheapest combination of a Seamix subscription and, where the volume needs more than that plan's monthly allowance, pay-as-you-go top-ups, at current list prices - so it is a price you could actually pay. The plan and any top-ups that figure is made of are named next to it above. Your own costs will differ depending on your supplier, garment complexity and revision count. Nothing here is a guarantee of savings.
