What Archer Touches
Every underwriting model has three layers. Archer only touches the first one.
INPUTS

Raw data (rent rolls, T12s, comps, property info) + routine assumptions your team makes the same way every time

CALCULATIONS

Two Data Streams, Merged Automatically
Your History
Every deal you've run becomes a data asset for the next one. Past rent rolls → rent comps. Past T12s → expense benchmarks. Past sale records → sale comps. Your institutional knowledge surfaced automatically.

Progressive Automation Levels
Every BYOM integration starts with Level 1 and expands. We work with your team to progressively automate more of the model.
From 12 manual steps to one workflow
Same model. Same outputs. Fraction of the effort.
+ high error rate from manual entry
What Archer handles automatically:
Your team focuses on analysis, not data entry
Your calculations and outputs — completely unchanged
Archer's engine lives in your workbook as new tabs — the "battery pack" that powers everything. But your calculation tabs, output tabs, and deliverables remain exactly as they are. Anyone who receives the model interacts with the same tabs they've always known.

Same Tabs They Know
This is the #1 objection killer:
"Will this change things for my clients or partners?" → No. Your calculations and outputs are untouched.
The Archer tabs power everything behind the scenes, but anyone receiving the model works with the same tabs they've always known — no Archer account required.
Four layers of value — one experience
Each layer wraps around your model, adding capability without adding complexity.
Most clients ask — "can you plug into our model?" That's Layer 1. The real opportunity is discovering that Layers 2–4 are all possible with Archer + BYOM.
