Overview

Byttis is a Norwegian clothing swap marketplace where users trade clothes using an internal credit system instead of cash. We built the complete platform from marketplace features to a double-entry ledger system that tracks every credit transaction.

The Ledger

Every credit transaction runs through a double-entry ledger system with matching debit and credit entries. This gives Byttis full auditability and prevents currency manipulation or accounting errors.

Ready for Launch

The platform is in pre-launch at byttis.no with the core swap functionality complete. The credit system handles complex multi-party trades where swaps don't need to be 1-to-1 between two users.

FAQ

Get quick answers about working with us and our approach to digital solutions.

What’s included in a monthly retainer?

01

Each retainer includes a set number of design or strategy requests per month, priority turnaround, and a dedicated point of contact. It’s built for teams who want ongoing support without starting from scratch every time.

How many requests can I make per month?

02

We typically handle up to two active requests at a time, with new ones queued as they’re completed. Most deliverables are turned around within 48–72 hours, depending on complexity.

Is a retainer better than a one-off project?

03

If you need ongoing design support, faster turnarounds, or regular iterations, a retainer is often more cost-effective and collaborative than starting fresh each time.

Who will I be working with?

04

You’ll work directly with senior designers and strategists. No middle layers, no fluff—just experienced people doing the work.

Do you work with international clients?

05

Yes. Most of our clients are remote. We’re fully set up to collaborate across time zones with clear communication and shared tools.
