Swoshit

Safe private deals, built from the ground up

We helped build Swoshit from the ground up – a service that makes it safer to buy and sell high-value items between private individuals. Buyer and seller sign a digital agreement with BankID, the buyer pays through Swoshit, and the money is held until the deal is done.

The challenge

When you buy a horse, a bike or anything else expensive from a stranger, the buyer usually carries all the risk. Fake listings, missing payments and unclear agreements are common problems. The goal was a service that would:

  • Protect both buyer and seller without being complicated to use
  • Verify who the parties are and document what they agreed
  • Offer payment methods people actually want to use, even for large amounts
02

The solution

We built the platform in Laravel, from idea to production:

  • Registration and verification – sellers create an account and are identified with their ID, so both parties know who they are dealing with.
  • Digital purchase agreement with BankID – buyer and seller fill in the terms of the deal and sign the agreement with BankID.
  • Payment via Stripe – the buyer pays with Swish, card or Klarna, and which methods are shown is set automatically by the amount.
  • Money held until the deal is done – the payment is reserved and paid out to the seller only when the buyer approves or the inspection period ends.
  • Clear pricing – sellers see the fee and their payout up front, and no fee is charged if the deal doesn't go through.
  • Marketplace integration – sellers on connected marketplaces can activate Swoshit directly in their listing.

The result

Swoshit is a complete service for safe private deals, built to grow alongside more marketplaces.

  • Security for both parties – verified users, signed agreements and money held until everything checks out.
  • Easy to pay – Swish, card and Klarna in one flow.
  • The whole deal documented – a record is there if anything goes wrong.
  • Ready to scale – payment methods, fees and inspection periods can be tailored per marketplace.
