FlowManual

AI back-office platform that reviews construction bids, contracts, change orders, and invoices

FlowManual is an AI platform for construction back-office document review. General and specialty contractors upload bids, contracts, change orders, buyouts, invoices, submittals, and specs; the platform reads and cross-compares them to flag scope, price, and exclusion changes, each finding linked to its exact line in the source PDF. It can also draft RFIs from flagged gaps and extract equipment schedules for first-pass cost estimates. The product runs in the cloud, on a customer-managed machine, or fully on-premise.

Not disclosed on FlowManual's own site. Backed by Y Combinator (Summer 2026 batch); the tools-data source note and third-party YC batch trackers describe the round as "YC pre-seed." Y Combinator's standard batch investment is $500K, but this exact amount has not been independently confirmed for FlowManual specifically raisedEarly Stage
Founded Not publicly specified - company is a Y Combinator Summer 2026 batch member; founders' bios (recent Harvard leavers) suggest a very recent founding, but no explicit founding date is published · No named paying customers publicly disclosed. Marketing/demo pages reference "Cedar Ridge Mechanical" in a worked bid-to-contract example (rooftop units, VAV boxes, ductwork), which reads as an illustrative sample scenario rather than a confirmed customer

WHY IT EXISTS

Why This Tool Exists

The Problem

Contractors manually cross-check subcontractor bids against awarded contracts, change orders against original scope, and vendor invoices against locked buyouts - work spread across hundreds of pages of specs and drawings. A missed clause, an unnoticed scope addition, or a repriced line item can mean absorbing thousands of dollars of unbid work or missing a margin-eroding price change before it is too late to act.

The Solution

FlowManual uses Anthropic Claude models to read and compare construction documents, pinning every flagged scope, price, or exclusion change to its exact location in the source PDF. It compares change orders to the original contract, checks vendor invoices against locked buyouts in seconds, drafts ready-to-send RFIs from flagged gaps or conflicting clauses (citing the source document and clause), and extracts equipment schedules from specs to build first-pass cost estimates.

Exactly what this tool uses and how

Input
What it needs
Required:Construction bid or contract PDF, Comparison document (contract, change order, invoice, or buyout/purchase order) for cross-checking
Optional:Project specifications, Submittal documents, Equipment schedules
Formats:PDF
Output
What you get
Format:In-app flagged-findings view with line-level citations into the source PDF, plus generated RFI drafts and cost-estimate line items
Fields:Flagged scope/price/exclusion changes with severity and margin labels, Clause references and source-document citations, RFI drafts citing flagged clauses, Buyout-vs-invoice price deltas, Equipment schedule line items for first-pass estimates
Algorithm
How it works
Model:Built on Anthropic Claude models for document analysis (specific model version not publicly disclosed)
Accuracy:Not publicly specified - no vendor-published or independent accuracy benchmark was found
Privacy
How your data is protected
Retention:Not publicly specified as a fixed period; company site states users can export or delete their data at any time
Training:Company site states a "zero-retention, no-training" policy with Anthropic (the backend model provider) and that original files are never transmitted for model training; customer data is stated to be siloed per account with no pooling across companies
Compliance:SOC 2 Type II described as "in progress" (not yet certified as of research date), Penetration testing described as "scheduled" but not yet completed per company site, No ISO 27001 or other third-party security certification found
API
Integration
Endpoint:Contact vendor for API access
Method:Not publicly documented
USE CASES

Use Cases

  • ·Comparing subcontractor bids against awarded contracts to flag scope, price, and exclusion changes before signing
  • ·Reviewing change orders against the original contract scope to price added work correctly and avoid absorbing excluded scope
  • ·Comparing vendor invoices against locked buyouts/purchase orders to catch price changes while there is still time to act
  • ·Auto-drafting RFIs from flagged document gaps or conflicting clauses, citing the source clause
  • ·Extracting equipment schedules from specs to build first-pass cost estimates
  • ·Checking submittals against specification requirements
