Customer Stack

Reference architectures by customer size.

What the technology stack looks like at each customer tier. Where OmniTakeoff fits, what it replaces, and what it complements. The accounting + PM + document-management vendors customers actually run.

Architectural patterns

Patterns we've observed across customers

Pre-takeoff stack matters less than post-award

Customers focus their evaluation on takeoff-tool features but their actual stack risk lives in the post-award integration. ACC + Procore + accounting integration is the workflow customers ask us about most after they're live.

Document-of-record migration is the slowest piece

Moving 5 years of bid PDFs from one system to another is logistics, not technology. We help with the import scripts; the customer's IT/admin team owns the cutover. Plan a 4–6 week document-of-record migration alongside the takeoff cutover.

Comm-layer choice is sticky

Customers don't migrate Teams/Slack just because they bought new takeoff software. We support both equally. Customers in regulated environments lean Teams; customers running modern dev/CSM workflows lean Slack.

Want a stack-fit assessment?

We'll diagram your stack with you.

60-min Zoom: bring your current tooling list, we'll diagram where OmniTakeoff fits, what it replaces, what it complements, and what migrates with no effort vs needs a project plan. Output is yours regardless of whether you become a customer.
