FlowManual
AI construction takeoff and estimating software that links drawing quantities straight into a priced bid.
The repositioning matters: FlowManual is a takeoff-and-estimate tool that also reads contracts, not a contract reader with extras. If your estimating lives in a spreadsheet you re-key by hand, the linked-quantity refresh and the protected manual edits are where the hours come back — a revised drawing changes a duct run, and you see which accepted quantities moved instead of hunting every row. It suits mechanical, ductwork, and concrete subcontractors and GCs who want the drawing, the quantities, the rates, and the contract review in one project. If all you need is someone to read a spec before you sign, you are buying more software than the job requires, and standalone takeoff tools such as

Skip FlowManual if you only need someone to read a spec or contract before you sign and you are not producing takeoff quantities or a priced estimate yourself.
The free plan's daily usage allowance resets every day, so a busy estimating week can stall mid-afternoon while you wait for tomorrow's quota.
The free plan fits a solo estimator or a small trade shop testing takeoff against PDF plans, with a daily usage allowance, all features, and unlimited projects and uploads at $0. Firms running real bid volume move to Pro, sized through sales rather than a published seat price — which puts FlowManual's commercial tier in the same conversation as full estimating suites, while its free plan undercuts standalone takeoff-and-spreadsheet combinations.

About FlowManual
FlowManual is construction takeoff and estimating software for general contractors and trade subcontractors. You upload PDF drawings, set and verify the sheet scale, then count equipment and fixtures, trace ductwork runs by size and elbows, trace piping by diameter and service, and measure concrete areas and volumes directly on the plan. Each count and measurement can be added, edited, accepted, or rejected against the source sheet before it enters the estimate. Accepted quantities flow into a linked estimating workbook where you apply your own material costs, labor rates, formulas, multiple sheets, and markup — the vendor's own published example shows supply duct at 126 LF with $42.00 material and $18.00 labor per unit rolling up through a 10% markup to a total bid. Linked rows pull you back to the source drawing to verify a number, and when a revision lands you can compare drawing versions, review changed regions, and refresh the linked quantities while manually edited or locked quantities are held back for your review. The scope behind the number gets read in the same project: specs, contracts, quotes, and invoices with scope, costs, deadlines, and exclusions highlighted in the PDF, plus bid leveling that puts subcontractor proposals side by side by scope and carries your selections into the estimate. It competes with a standalone takeoff tool plus a spreadsheet, not with a general document chatbot. Workflows are aimed at the trades doing the counting — mechanical equipment and piping, ductwork, concrete slabs and footings, and general counting for custom items like doors, lights, and fixtures. Excel import and export means you keep your rate library, and estimates export to Excel, CSV, or a proposal PDF. Documents sit in a hosted workspace with AES-256 encryption at rest, per-company isolation, SSO, MFA, audit logging, and enterprise deployment options. FlowManual is backed by Y Combinator.
Behind the Verdict
FlowManual's core claim is that the drawing and the estimate should never be two files, and the product is built around defending that claim. Takeoff is not generic: mechanical equipment and fixture counts, pipe runs recorded by diameter and service, ductwork by run, size, and elbows, concrete slabs, footings, and volumes, and general counting for custom symbols such as doors and lights. Quantities are reviewed item by item against the source sheet — accept, edit, or reject — before they enter the workbook. The estimating side is an editable workbook with formulas, multiple sheets, and markup, so your material costs, labor rates, and overhead stay yours. The vendor's published example walks a mechanical scope from 126 LF of supply duct through direct cost, 10% markup, and a total bid, which is the shape of output an estimator actually hands to a chief estimator. The feature that separates FlowManual from a takeoff tool bolted to Excel is what happens on a revision. Drawing revision comparison surfaces the changed regions, and the refresh passes those changes to the linked takeoff quantities, while quantities you edited and locked by hand are protected from being overwritten. Anyone who has spent a Friday afternoon re-checking a re-issued M-series sheet knows that is the actual time sink. The scope-review half does the quieter work: specs, contracts, quotes, and invoices are read in the same project with scope, costs, deadlines, and exclusions highlighted, and bid leveling compares subcontractor proposals by scope so selections carry into the estimate. Where it does not fit: nothing about the vocabulary is built for non-construction work, and the software will not produce a finished bid number — you still supply labor, markup, and final judgment. The free plan is limited by a daily usage allowance that resets every day, which is generous for a solo estimator exploring the tool and thin for a high-volume estimating department pricing several jobs a week. Firm-wide rollouts go through a sales conversation and run on FlowManual's hosted service rather than an on-premise install, so plan around that. Companies looking for scheduling, payroll, or full ERP project management are shopping in the wrong aisle. And because estimates export to Excel, CSV, or a proposal PDF, teams that want every downstream system wired up should expect to work inside the workspace and export out.

Real-world workflow fit
Concrete scenarios for the personas FlowManual actually fits — and what changes day-one when you adopt it.
Upload the M-series PDF drawings, set and verify the scale, count air handlers, pumps, and air devices, and trace pipe runs by diameter and service. Accept the reviewed quantities into the project's estimating workbook, apply your own material and labor unit costs with a 10% markup, and check the total bid against the GC's contract for scope adds.
Outcome: A priced mechanical bid with every quantity traceable back to the sheet it came from, and a contract review that flags cost, deadline, and exclusion changes before you sign.
Compare the new drawing version against the one you priced, review the changed regions that FlowManual surfaces, and refresh the linked takeoff quantities while your manually edited and locked counts stay protected for review.
Outcome: The estimate reflects the revision without a full re-measure, and you can see exactly which accepted quantities moved rather than trusting that the spreadsheet still matches the plan.
Sign up with no card, upload drawings on the free plan's daily allowance, count fixtures and measure floor finishes, and build the first estimate in the workbook using an imported Excel rate library.
Outcome: A first priced takeoff with nothing abandoned — your rate library comes in through Excel, the estimate exports to Excel, CSV, or a proposal PDF, and upgrading to Pro is only necessary when the daily allowance becomes the constraint.
Use Cases
- Compare your bid against the GC's contract to catch scope adds and price changes before signing
- Review a fresh specification package in First-Read Mode to automatically highlight scope, deadlines, and exclusions

- Track change orders from initiation through approval with structured flagging
- Generate an exposure summary showing total dollar risk from unflagged changes before award
- Use takeoff counts with pin-to-sheet verification to cross-check equipment schedules
- Price a mechanical, ductwork, or concrete scope from PDF plans without re-keying quantities into a spreadsheet
- Refresh a bid after a re-issued drawing sheet and see which accepted quantities moved
Models Under the Hood

Limitations
- FlowManual is a hosted service: your drawings, estimates, and supporting documents live in FlowManual's workspace, encrypted at rest and isolated per company, with export and deletion available, and enterprise deployment options exist for firms that need more.
- Free-plan usage is capped by a daily allowance that resets every day, so high-volume estimating departments will run out before the week is done; firm-wide rollout runs on the Pro plan, which is sized through a sales conversation.
- It is a takeoff, estimating, and scope-review tool, so you still supply your own unit costs, labor rates, and markup, and the software will not hand you a finished bid number.
- Nothing in the vocabulary is aimed outside commercial construction, and there are no documented third-party marketplace integrations — plan to work inside the workspace and export to Excel, CSV, or a proposal PDF.

Where the pricing makes sense
The company stage and team size where FlowManual's pricing actually pencils out — and where peers do it cheaper.
The free plan fits a solo estimator or a small trade shop testing takeoff against PDF plans, with a daily usage allowance, all features, and unlimited projects and uploads at $0. Firms running real bid volume move to Pro, sized through sales rather than a published seat price — which puts FlowManual's commercial tier in the same conversation as full estimating suites, while its free plan undercuts standalone takeoff-and-spreadsheet combinations.
Setup time & first value
How long it actually takes to get something useful out of FlowManual — broken out by persona, not the marketing-page minute.
Solo estimators get to first value in a single sitting: sign up without a card, upload a PDF drawing, set and verify the scale, and start counting. Teams bringing an existing rate library should budget an extra session to import their Excel rates and assemblies. Firm-wide Pro rollout adds the sales sizing conversation plus SSO and audit-log setup, so plan on a few days rather than an afternoon.
Switching to or from FlowManual
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a takeoff tool plus Excel: import your rate library through Excel, rebuild the estimate in FlowManual's workbook, and link each accepted takeoff quantity to its source sheet.
- →From manual PDF markup: upload the drawings you already mark up, set the scale per sheet, and replace hand tallies with accepted counts that flow into the priced estimate.
- →From a generic document chatbot: move the contract and spec review into the same project as the takeoff so scope, cost, and deadline flags sit next to the quantities they affect.
- ↗To Excel or CSV: export the estimate workbook or the raw quantities and take the rate library with you.
- ↗To a proposal PDF: generate the finished bid document straight from the estimate for submission.
