30× D2C revenue growth in 3 years
A B2B client with a single active channel (Allegro) and negligible direct sales. Over three years, we built a complete D2C ecosystem: phone sales, four marketplace channels and their own online store. The result: around 30× growth in direct sales to end customers.
Campaigns taken over and results turned around
The client was locked into an unfavourable contract with a large agency, and in the account we took over, advertising was running below the profitability threshold despite a substantial budget. We stopped the campaigns and rebuilt the structure from the ground up, billing by the hour instead of taking a share of the budget. We scaled spend gradually and kept return on ad spend positive at every stage.
2,000 descriptions adapted automatically
The client had 2,000 descriptions written for Allegro that did not meet the requirements of another platform (Black Red White). We built an automation in Make.com that analysed content and photos and then rewrote the descriptions to the platform's standards without touching SEO. 2,000 products ready to publish, with no manual work.
How we work together
A partnership-based notice period
Instead of annual subscriptions unrelated to results, we agree on a two-month notice period. The success of your account is the success of our agency.
Every process included
We charge no extra fees on advertising budgets or the number of listings. Listings, content and marketing are all included in the engagement.
A flexible scope
You can hand everything over to us or only a selected part of the process. We adjust the scope to your needs, not the other way around.
More than an agency. An ecosystem of people and partners
Commercraft is a network of proven partners: technology, operations and creative. We deliver every project with experts chosen for the specific challenge. One expression of this partnership is Ecommerce Unplugged – an event we organise with partners for our clients: an informal meeting of practitioners, with no sales pitches.
