Sound familiar?
A shop full of talent, run on sticky notes.
Spreadsheets, email threads and a whiteboard can hold a sign shop together — right up until they can’t. Every gap between systems is a place where money quietly leaks out. That’s the case for sign shop management software that holds quoting, production, purchasing and invoicing on one record.
Two people quote the same job off two different price lists.
The quote says one thing, the job sheet says another.
The only person who knows where a job is at is the boss.
Material costs live in a spreadsheet nobody fully trusts.
The same job gets re-keyed into three different systems.
Nobody finds out the margin was gone until the invoice.
What Sign OS is
The full loop, closed.
Define what you sell → price it → quote it → build it → buy for it → invoice it. One record travels the whole way. Click a stage.
stage 01 / 06
Define what you sell, once
Products in Sign OS are living recipes — substrates, machine time, labour, options and markup. Build it once and every quote after that prices itself the same way.
- Shared global catalogue of materials, machines and processes
- Shop-level overrides on everything
- Your markup rules applied at quote time

Watch it work
Ninety seconds, tops.
Three short videos: the full loop in a minute, quoting that wins work, and ReAct — the private AI agent working the counter with you.
The full tour
One minute through the whole loop: recipe-driven quoting, the production timeline and floor boards, purchasing, Xero-synced invoicing and the online storefront — one record from enquiry to invoice.
Quote in minutes
Recipe pricing in action: materials with real waste and yield, machine time and labour computed deterministically — so anyone on the team sends a defensible quote in minutes, not after dinner.
Meet ReAct
The AI operations assistant inside Sign OS: finds records, drafts quotes and raises purchase orders under your team's permissions, with an approval card before every write — and your data stays yours.
Meet ReAct
The first sign-shop assistant with hands.
Every Sign OS shop ships with ReAct — an operations assistant wired into the same pricing engine, records and permissions as your team. Not a chatbot bolted on the side: it acts, and you approve.
Does real work
Drafts quotes, creates customers, updates jobs, raises POs — through the same engine and rules as your staff. Every write shows an approval card before anything is saved.
Navigates for you
“Open the production timeline.” “Go to job J-204.” ReAct drives the app so you don’t dig through menus — especially handy on the counter with a customer waiting.
Reads the room
Ask what’s overloaded, what’s at risk, or how a department is tracking, and get a straight answer built from live production data.
More on how the assistant works, what it can and can’t do yet, and running it on your own ChatGPT or Claude account: AI sign shop software.
Guardrails, by design
ReAct’s tools are gated by the same 70+ per-user permission grants as everything else. Admins pick the approval mode; every mutation shows a card before it saves; every action lands in the audit trail. Floor staff’s ReAct can’t see a price — because floor staff can’t.
A flywheel, not a feature
Users rate ReAct’s answers in-app, and those ratings become training data. Every shop that runs on Sign OS makes the assistant sharper for every other shop — a compounding advantage that gets harder to copy every month.

Why Sign OS
Built by sign people, engineered like software should be.
Designed from years inside the industry — not by developers guessing how sign shops work. Three things set it apart:
Signage-native, to the millimetre
Sheets and rolls, sqm and lm, waste and yield, weeding and nesting — the pricing engine speaks sign shop, not generic ERP. It prices the way your estimator thinks, with depth horizontal software can't match.
One record, the whole loop
Enquiry → quote → job → floor → PO → invoice, one system, zero re-keying. Most tools cover a slice; Sign OS closes the loop, so every job makes the next one faster to quote and easier to run.
AI with hands, not a chat widget
ReAct executes real operations under real permissions, and every rated interaction makes it sharper. As the assistant earns trust, Sign OS moves from software you drive to a shop that runs itself.
Every decision starts with one question: does this move a job from enquiry to paid with less friction than yesterday?
Questions
Straight answers.
What is Sign OS?
One connected platform for a whole sign company — CRM, estimating, quoting, production, scheduling, purchasing, invoicing and accounting, plus ReAct, an AI assistant that works inside all of it. Instead of ten tools that don't talk to each other, every stage of a job lives in one place.
How mature is the platform?
The core loop — quote, produce, purchase, dispatch, invoice — runs in production today, along with your own no-code online store, custom domains, VIP & multi-shop supplier/installer portals, two-way Xero and QuickBooks accounting sync, desktop file sync for Windows, macOS and Linux, versioned artwork proofs with customer sign-off, and custom reports. Storefront card checkout is available once your Stripe account is connected and verified — until then, orders land as enquiries for you to confirm and invoice. Two things are built but not switched on yet: the MYOB connection (MYOB charges for developer access) and the Outlook/Gmail tag companions (connecting a mailbox still needs us to set it up with you). The status board above reflects the current release.
How does quoting stay accurate?
You define each product as a recipe once — materials, machine time, labour, markup. The deterministic engine then prices every quote the same way, deriving usage, waste and time automatically. Overrides are always allowed and always visible.
What exactly can ReAct do today?
Find any record in plain English, create and update quotes, jobs, customers and POs (every write behind an approval card), navigate the app for you, and summarise live production. It runs under the same per-user permission grants as your staff, and admins choose how strict approval mode is.
What about my accounting system?
Sign OS generates operational invoices and syncs two-way with Xero and QuickBooks today — sending invoices out and reading payment status back. The MYOB connection is written and tested, but MYOB charges for developer access, so it stays switched off until we buy in; we won't put a date on it. Sign OS is not the general ledger; your accountant keeps their system.
Who sees what?
Roles plus 70+ per-user grants control everything down to line costs, margins and buy prices. Floor staff never see a dollar figure. Approval policies can gate quote sends, invoice issues, PO sends and variations.
What support do we get?
Guided onboarding when you join, email support at [email protected], and a growing library of shop-floor guides. ReAct also answers how-do-I questions inside the app, against your own data.
