Three engines built for landlords.
Atlas runs in the background, capturing every property cost and modelling Section 24 so your true post-tax cash flow is always in view.
The Portfolio Email Chaser
Connects to Gmail/Outlook to find digital invoices from letting agents, insurers and utility providers — auto-tagged to the right property.
The “On-Site” Nudge
Detects card spend at Screwfix, Wickes or B&Q and pings your phone to snap the receipt before it hits the van floor.
