Welcome to ACTA
Your secure, all-in-one platform to manage property sales, legal docs & communication.
We were tired of countless email threads, misplaced documents and the lack of transparency throughout the process of purchasing a property. So we built ACTA.
Sale/Purchase audit checklist
Create, share, and track every property you’re handling — from offer to completion — all in one place.
Easy Collaboration
Collaborate with solicitor, buyer, FX partners, real estate agents, and/or vendor, securely with one-time access links or QR codes — no confusion, no faff.
Built-in Messaging
Keep all chats, document notes, and updates in one thread linked to each property. No more chasing emails.
Smart Document Handling
Upload and share files directly with contributors. Everything stays organised, tracked, and accessible 24/7. When you're done, it's just a one click delete to remove all documents and data associated with a property.
Simple Payments
Each registered property is a simple one off charge of £30.00 via Stripe checkout. Once a property is created you can invite an unlimited number of contributors, and have a document limit of 50 documents per property.
Safe & Secure
Bank grade encrypted data, role-based access, and one-time invites mean your sensitive documents stay private and protected.
