Photograph the notes. Stasora reads back
the estimate. Same ten minutes.

Stasora is the AI contracting platform that reads the worksheet you filled in on the tailgate, drafts the estimate line by line, and raises a flag on every quantity a paragraph could not honestly tell it. Photograph it on the phone; it is priced and waiting on the laptop. Then it carries the same job through proposal, change order and invoice, and a named human approves each one before a client sees it.

Example estimate, EST-1, bathroom remodel in Noe Valley, drafted from a photographed job-walk worksheet. Demo tub surround and floor, haul-off, two loads, $640. Rough plumbing, fixtures stay in place, $2,850, with a licensed plumber and permit notice attached. Porcelain floor tile, set and grout, 48 square feet, $1,940, flagged low confidence because the worksheet says about 48 square feet with a question mark. Shower surround tile, set and grout, 96 square feet, $3,120, flagged low confidence because the square footage came off a sketch. Vanity, faucet and mirror, install, $1,480. Paint, two coats, walls and ceiling, $860. Estimate total $10,890, a range of $10,400 to $12,100 with three assumptions and two exclusions. The draft is waiting on R. Okafor to approve it.

Yesterday's worksheet is already an estimate.

You photographed the page on the tailgate and it synced overnight. The draft is waiting for your corrections, not for your typing. Two lines are flagged low confidence, and they are the two you would have guessed at anyway.

A line priced from the supplier catalog carries the price you can actually buy at today. Measure the floor properly, clear the flag at the counter, and the office sees the new total before you are back in the truck.

The same copilot sits at the bottom of every screen on the phone and down the left side of every screen on the desk. It reads your spine, your projects, your price history, your approved documents, and it answers by drafting the document you asked for. In draft state, with your name still required on it.

Approve the log The client update drafts itself from the approved log, and still waits for you

It answers with a document, not a paragraph.
A question about a change order returns a change order, priced from your own history, with the evidence chips still attached to the lines they justify. You read a document you recognise, not a summary you have to trust.
It reads your spine, not the open internet.
Your projects, your price book, your approved contracts, your logs. That is why the numbers are yours and why every line can say where it came from.
Asking is not sending.
Everything the copilot produces lands in draft. It cannot send, sign, bill or file. The approve button is the only door out, and a person has to press it.
The same copilot on the phone and the desk.
Ask it from the bottom bar in the truck, ask it from the desk panel at seven. Same spine, same answer, same total to the cent.

Four pillars. The same project underneath each one.

An estimate becomes a proposal becomes a contract. The contract becomes a schedule of values. Change orders roll into contract value. Invoices bill against it. Every dollar on every document traces back to one line.

StasoraI drafted eleven lines from your worksheet and the walkthrough. Two tile quantities are low confidence; I flagged them rather than guessing.

YouMake the demo two loads of hauling and price the tile from the catalog.

StasoraDone. Line 1 is now 2 loads. Line 4, the porcelain floor tile, now carries the supplier catalog floor of $3.48 per square foot on the tile itself, with the labour still from your history. Nothing was sent.

YouThe owner is supplying the cabinets. Take them out and say so.

StasoraCabinets are install only now, and "owner supplies cabinets" prints in the assumptions block on the estimate itself.

We will remove the existing cabinets, counters and flooring and haul them away, relocate the sink supply and drain, add two dedicated appliance circuits, lay porcelain tile across the kitchen floor, and install the cabinets you supply. Permit fees and appliance hookup are not included. Plumbing and electrical work is performed by licensed trades and inspected by the city.

Approval gate

Approve and send names you as the approver and records the time and device. The client signs on their phone; you see the signed state on yours.

The proposal is written in the client's language.
From an approved estimate, the copilot drafts a proposal a property owner or an upstream GC can read without a glossary, with your brand kit on every page and the exclusions carried forward word for word.
Native e-sign, drawn or typed.
The client opens a link on their phone, draws a signature with a finger or types a name, and the signed contract lands on the spine. Contracts and lien waivers ship as templates with jurisdiction-varies and attorney-review notices printed on the paper. A lien waiver always prints them. A proposal prints them by default, and you can turn them off for that proposal.
Change orders come from the field, not from memory.
When a daily log records work outside the contract, the scope-creep flag drafts the change order with the evidence attached. Approved change orders roll into contract value, so the invoice already knows.

The ruleNothing client-facing leaves draft state on its own. Approve and send names a human, stamps the time, and records the device it came from.

Client update · draft

Hi Priya, demolition wrapped up today and your tile is on site. We found framing behind the north wall that differs from the plans; a short change order is on its way for your review.

Capture is built for gloves, glare and no signal.
A full-bleed viewfinder, a shutter the size of a thumb, and an offline queue that holds photos, voice notes and punch items until the phone finds a signal. Paper is a first-class input: a photo of a filled-in worksheet is a workflow, not a migration step.
The field layer speaks Spanish. That is what the field layer means.
Captures, daily logs and punch items can be recorded and read in Spanish, so the crew writes the day in their own words and the office reads the same record in theirs. It is the capture side of the product, not the client side: proposals, change orders, invoices and the portal are English today, and we will say so plainly rather than imply otherwise.
Client updates are drafted, never auto-sent.
From the approved log, the copilot drafts the update the client actually wants: what happened, what arrived, what changed. You read it and send it, or you do not.

The ruleOffline capture is a requirement, not a feature. What the crew captures in the basement is on the office screen the moment the phone finds a signal.

Progress billing tied to the schedule of values.
Each invoice bills this period's percent complete per SOV line, holds retainage at the contract rate, and picks up approved change orders automatically. Every figure on the invoice traces to a line on the contract.
Proof on the invoice, not in a separate email.
Photos from the daily logs attach to the lines they prove. A client who can see the tile laid does not call to ask whether the tile was laid.
Lien waivers and payment links, templated and hosted.
Conditional and unconditional waivers are generated as templates with jurisdiction notices. Payment requests are published for the balance owed through Stripe-hosted pages, so card data never touches our servers or yours.

The ruleThe total on the phone and the total on the laptop match to the cent, because it is one number, not two copies of it. You never reconcile your own software against itself.

Cross-device continuity

Start it on the phone. Finish it on the laptop. Or the other way around.

Having the same screen on the phone and the laptop is not the same as the work moving between them. A document that cannot hand itself to the other device is a dead end wearing the costume of a feature. Stasora builds against three laws, and a test in the build gate enforces them.

First law

Every change lands on the spine.

A photo taken in a basement with no signal waits on the phone only long enough to reach the cloud. Nothing you capture ends its life on one device or in one browser tab. Local storage is a queue, never a destination. The office sees it the moment the phone climbs the stairs.

The phone holds it only until the cloud has it

Second law

Phone and laptop both create, read and edit. Not just view.

The foreman opens the change order on the phone and edits the quantity. The estimator opens the same change order on the laptop and sees the edit, with "last edited on the web app, 12 minutes ago" printed on the document. Read-only on the phone is an exemption somebody has to justify in writing, not a shortcut anyone can take quietly.

The same total, to the cent, on both screens

Third law

Concurrent edits fail loudly, never silently.

If two people change the same line at the same time, the losing edit is shown to the person who made it, and they choose. A discarded edit that nobody was told about is data loss wearing the costume of a sync, and it is the kind of bug you only discover in an argument with a client.

Provenance visible, conflicts surfaced, nothing dropped quietly

Seven rules we built in, on purpose.

Contracting runs on trust and on money. The AI in Stasora is allowed to be fast because these rules are structural, not a line in a prompt asking it to be careful.

AI drafts. A named human approves.

No estimate, proposal, change order, client update, invoice or payment reminder leaves draft state without a person pressing approve in the app. The approval records who, when and from which device.

There is no auto-send anywhere in the product. Not as a setting, not as a plan feature, not for reminders.

Estimates are ranges with assumptions.

Every estimate shows its range, its assumptions and its exclusions next to the number, not behind a link. A quantity the AI extracted from a photo, a paragraph or a sketch carries a confidence flag, and low confidence is a flag you clear, not a number you inherit.

Your cost never reaches a client document.

Unit costs, crew rates, margins and "our cost" live in fields that the proposal, change order, portal and invoice renderers cannot read at all. It is built into how the data is stored and queried, not into a prompt.

Every client-facing render passes an automated no-cost-leak check before it goes out. The reason it is structural rather than careful is simple: a careful habit fails once, on the busiest day of the year, on the page a client keeps.

Every dollar traces to a schedule-of-values line.

The contract becomes a schedule of values. Progress invoices bill percent complete per line, retainage is held at the contract rate, and approved change orders roll into contract value so the next invoice already knows about them.

The phone and the laptop show the same total to the cent. You never reconcile your own software against itself.

Field-first, offline-first, glove-first.

Capture works in sun glare, with gloves on, in a basement with no signal. Targets are big, the shutter is the largest control in the app, and the offline queue is visible so nobody wonders whether the photos made it.

Large type is a setting, corrections can be spoken, and a photo of a filled-in worksheet is a first-class input. Tech the crew will not use is worse than no tech.

Not a lawyer. Not a licensed professional.

Contracts and lien waivers ship as templates with jurisdiction-varies notices and an attorney-review prompt printed on the paper. Structural, electrical, plumbing, gas and code-adjacent work carries a licensed-professional and local-building-department notice. On a proposal, each notice prints by default and you can turn it off for that proposal. Change orders and lien waivers always print every notice they carry. The wording of every notice is fixed.

Stasora never suggests skipping a permit or an inspection. It cannot be configured to.

Notices, printed on the line

NoticeElectrical work is performed by a licensed contractor and inspected by the local building department. Permit required.

TemplateLien waiver forms vary by jurisdiction. Have an attorney review before use.

Your data leaves with you.

Every project, estimate, contract, log, photo and invoice in your workspace is yours to take with you: export on request today, self-serve export before billing turns on, in formats another tool can read. Month to month means you can leave, and leaving means taking your history with you.

Your workspace is walled off from every other contractor's at the database level. Payment card data never touches our servers; those pages are hosted by Stripe.

Built for the whole trade, not one flavour of it.

A workspace declares what kind of business it is. That single choice tunes the vocabulary, the templates, and who the paying client is, without forking the product.

General contractor

You run subs, schedules and a schedule of values. The client is usually a property owner. Bid invitations, sub scoping, pay apps and lien waivers are part of the spine, not an add-on.

Client: Property owner
Templates: Proposal, contract, SOV, pay apps
Field: Daily logs across trades, punch, inspections

Remodeler

Kitchens, baths, additions. Photo-first estimating and change orders that write themselves when the wall opens are the difference between a profitable job and a story you tell later.

Client: Property owner
Templates: Estimate ranges, client-language proposals
Field: Walkthrough capture, scope-creep flags

Specialty trade

Electrical, plumbing, HVAC, roofing, concrete and the rest. Your paying client is often an upstream GC, so the documents speak that language: scopes, submittals, progress billing with retainage.

Client: Upstream GC or owner
Templates: Trade-tagged price book, progress invoices
Field: Licensed-professional notices where they belong

Out of scopeHome-service dispatch, flat-rate service calls, tech routing and memberships are a different business with different workflows. Stasora does not pretend to run them.

Pricing

Flat. Unlimited users. Month to month.

One price per workspace, not per seat, so the whole crew is on the same spine and nobody is sharing a login in the truck. AI usage is shown in dollars you can read, never in credits you have to convert. Stay, and the price steps down on a schedule published here and in our Terms.

The ladder

The steps at months 7, 13 and 25 are the published price, the same table as section 3.1 of our Terms, so each one arrives on the first day of its month with no notice letter and nothing to ask for. Switching between Field and Office keeps your months. Cancelling starts you again at month 1, and there is no pause that keeps them.

A customer without a founding seat never pays less than a founding partner with the same tenure.

Founding partners

$99 and $249, locked for 24 months

A small group of contractors who run their real jobs on Stasora this year and tell us what is wrong with it. The price does not move for two years. Then you join the ladder at your own step: $119 or $289 if you never left, on 60 days' written notice.

Users

Unlimited, on purpose

Per-seat pricing punishes the shop for putting the foreman on the app. Flat pricing means the person holding the camera has an account.

Dollars, never credits

What the AI cost this month is a number in dollars on your billing page, capped per plan: $2 Pipeline, $60 Field, $180 Office. No token math, no credit packs.

Today

A plan is not bought on this page: Field and Office are bought through Stripe after you sign up, from your workspace's billing page. Signing up is free and takes you straight into Pipeline. The prices and the steps above are final, and founding-partner pricing is confirmed in writing before anything is charged and claimed with your founding code at checkout when billing turns on.

Scope

Published, fixed, the same for everyone

These are productized engagements, not a rate card. Work outside the scope above is a written change order at $250 an hour, never a surprise line on an invoice.

Commercial and multi-project

Quoted, not list-priced

A shop running commercial, multi-project work sits on the Enterprise plan, which is quoted annually rather than published. Tell us what you run and we scope it with you.

What it feeds

Anything done twice by hand becomes product

The rule that keeps this a ladder and not a consultancy: work we do by hand in two separate engagements becomes a ticket in the product, so the next shop does not pay for it.

Questions a contractor asks before switching.

Short answers, no marketing. If yours is not here, write to us and a person answers.

Does anything send itself?

No. Estimates, proposals, change orders, client updates, invoices and payment reminders leave draft state only when a named person presses approve in the app. The approval is recorded with who, when and from which device. There is no auto-send setting to turn on.

Can it really read my handwriting?

It reads a photographed worksheet the way a good estimator reads one: it pulls out the scope lines it can see, prices them from your history or the supplier catalog, and refuses to invent the numbers it cannot read. A quantity written as "~48 sf?" comes back as a flagged line, not as a confident price. Messy pages, coffee rings and arrows in the margin are normal; a quantity you never wrote down is still a quantity you have to supply.

Do I need an iPhone app?

No. Stasora is a web app today, and it works in your phone's browser, including job photos from the phone's camera. Anything you start on the phone you can finish on the laptop. The iOS app is coming soon.

Is the estimate my cost or my price?

Both live in Stasora, but only the price can reach a client document. Unit costs, crew rates and margins are walled off in the database from the renderers that produce proposals, change orders, portals and invoices, and every client-facing render is checked for cost-side values before it goes out.

How much of this works in Spanish?

The field layer does: captures, daily logs and punch items can be recorded and read in Spanish, so a crew can document the day in their own language and the office can read the same record in English. Client-facing documents, the proposal, the change order, the invoice and the portal, are English today. We would rather tell you the boundary than let you find it on a job.

What does the AI cost me?

AI usage is metered and shown in dollars on your billing page, capped per plan: $2 Pipeline, $60 Field, $180 Office. Nothing is priced in credits, tokens or packs.

Is Stasora giving legal or engineering advice?

No. Contracts and lien waivers are templates with jurisdiction-varies notices and an attorney-review prompt on the paper. Structural, electrical, plumbing, gas and code-adjacent suggestions carry licensed-professional and local-building-department notices. On a proposal these notices print by default, and you can turn any of them off for that proposal. Change orders and lien waivers always print every notice they carry. The wording of every notice is fixed. The product never suggests skipping a permit or an inspection.

What happens to my data if I leave?

It leaves with you. Every project, document, photo and log in the workspace is yours to take: export on request today, self-serve export before billing turns on, in formats another tool can read. Month to month means you can go; the export means you can take your history when you do.

What is the free start?

A workspace you set up in a conversation: your project types, finish level, service area and default markup, then a real job in your own words or a photo of a real worksheet. Your first estimate is drafted before you have entered a card. Founding partners run at $99 or $249 a month, locked for 24 months.

What is Stasora?

Stasora is the AI-native contractor platform for general contractors, remodelers and specialty trade contractors. Photograph your job-walk notes and it reads back a priced draft estimate, with every uncertain line flagged for your review. From there it drafts the proposal, the change order, the daily log and the invoice on one shared project record, and a named person on your team approves every one before anything reaches a client.

Is Stasora AI software for contractors?

Yes. Stasora is AI software built for general contractors, remodelers and specialty trades such as electrical, plumbing, HVAC and roofing. The AI drafts the estimate, the proposal, the change order, the daily log and the invoice, and a person on your team reviews and approves each one. Home-service dispatch is out of scope.

Can Stasora write bids and proposals?

Yes, as drafts you approve. Stasora drafts the estimate from a photo of your handwritten notes or a plain description of the job, then drafts the proposal from the approved estimate in words a client can read. The proposal carries your logo, license and business address. Once a named person approves it, you can email it to the client from Stasora, and the client signs online.

Does Stasora send anything without approval?

No. Nothing client-facing or financial is sent without your approval. Estimates, proposals, change orders, client updates, invoices and payment reminders stay drafts until a named person on your team approves them in the app, and every approval is recorded with who and when. Your costs and margins never appear on the client's copy.

What does Stasora cost?

Pipeline is free and covers the CRM and sales pipeline. Field is $149 a month and includes the AI drafting of estimates, proposals, change orders, field records and invoices. Office is $349 a month and adds progress billing with retainage. Each is one flat price per workspace with unlimited users, month to month, and the price steps down the longer you stay, on the schedule published on this page and in our Terms.

Where does Stasora run?

In the browser, at app.stasora.ai. Your work lives on one shared project record in the cloud, so it is there wherever you sign in. Signing up is free and starts you on Pipeline.

The rules

Every line on an estimate is labelled with where its price came from, such as your own notes, a price typed by hand, or Stasora's estimate, which waits for a person to check it. Your costs and margins never appear on the client's copy. Nothing client-facing or financial is sent without your approval.

Where it runs

Stasora runs in the browser at app.stasora.ai, on a laptop or a phone. The iOS app is coming soon. Built with a working general contractor as our design partner.
