Archian or Rapport3?
Rapport3 has a long record with large UK practices. Archian is made for smaller ones.
What Rapport3 does
Rapport3 helps architects and engineers cost their projects, record time and expenses, plan staff, send invoices and report on it all. More than 230 firms use it, and the ones it names are large: PRP has about 320 people.
Milient, a Norwegian software group, bought Rapport3 in October 2025, and plans to bring it into its range of products.

Where Rapport3 is stronger
- It has a long record with large, well-known UK practices.
- It suits firms with a studio manager and a finance team.
- It connects to accounting software that larger firms use, such as AccountsIQ.
Where Archian is different
- It's made for 3 to 30 people. It suits an owner who still designs, and has no one to set up and run the system.
- Our price is on our website. It's about £49 a person a month plus VAT.
- You build the budget first. The quote comes from the budget, so you know the gross profit before the client sees a price.
- It covers more of the practice. Applications, the cost plan, leave, reviews, CPD, recruitment, people planning, and the business model and objectives are all in the same place, for one price.
- We do the move. Your projects, clients and quotes come across before day one.
