③ Rig geometry — required for accurate anchor distance
Measure your stand once — upright at 90°, no spacers — and save it as a rig. Step-out spacers go in their own box below: at 90° a spacer adds its own length to the anchor distance; tilt the post and it adds more (a 200 at 30° adds 400). Defaults: Hilti DD350-CA on a DD-HD 30 stand.

Edges — tap a side on the picture
finished line open / free against wall / floor
Standalone
Tap a side to cycle: finished line → free / open (no perimeter cut or relief — standalone slabs, blocks and walls) → against wall / floor (the machine's guards keep the cut off the wall; the leftover strip is jackhammered out or left). Standalone frees all four.
② Machine
Pick the saw — it sets how deep it reaches, the overcut, and the relief cores. Machines that can't do this peno are greyed.

③ Are overcuts allowed?
No
Yes
Can the saw overrun past the finished line into the concrete you are keeping? No (default) — the overruns must be relieved. Yes — only where an engineer has approved it as safe; no relief cores.
Relief cores
Cores drilled so no cut overruns the finished line — at the 4 corners and where each internal cut meets the perimeter.
Core diameter

Standard
Clean edge
Same as Stitch: holes overhang outside the line and the scallops between them land ON it — a clean finished face, and each core covers a full pitch along the line.

🦺 Crew file
A client book starts as a copy of the current book — change what's special for them. The Quote tab asks which rates once there's more than one.
Starting copies the sample into YOUR book — then every number below is yours to change. Export = one file carrying the whole business: rates, your words AND the Company card (name, logo, ABN, bank, terms) — never the You card, that stays personal to each phone. 🔒 Export locked = the same file for your quoters: they price on your rates, but rates and terms won't move on their phones. The 🦺 Crew file carries the company badge (name, logo) and your words only — no prices at all. The boss chooses who gets what.

Entered once, kept on this device, printed on every quote so the customer can pay you. Travels with the business file — the office sets it once for every phone.
Take card payments straight to YOUR account: open a free Stripe account at stripe.com, make a Payment Link (no code, a few clicks), paste it here. Stripe signs up businesses in all eight of this app's countries — AU · CA · DE · IE · NL · NZ · UK · US (stripe.com/global). AU: a sole-trader ABN is enough · US: individual or LLC · everywhere else: sole trader or limited company. Do it by the rules and this is a real little business.
📜 Words on your paper
🧰 Your machines
Tick what you run — they come first on every quote, booking and docket, in this order.
🪪 Your titles
What your people are called. Each title starts a card with its switches — you change any one person's from there. Rename one and every card follows.
✅ Quote approvals
Off, nothing changes. On, someone with “Can approve quotes” on their card ticks a quote before it goes — one tick is enough, and a change to its prices needs a fresh tick. Invoices are never held up.
📥 Xero / MYOB inbox
Xero and MYOB both give your business a private email address that drops a PDF straight into your books — Xero calls it Files, MYOB calls it the In Tray. Put it here and your invoices and dockets will offer to go there, with the address already on your clipboard.

Where to find it. Xero: Settings → Files → the address under “send files to this email address”. MYOB: Purchases → In Tray → your unique email address.

Nothing is sent by us and nothing passes through our servers — the paper goes from this device to your own accountant's inbox. The last tap is yours.

🦺 Crew — who got what
Who gets what: a wage cutter gets the 🦺 crew file — the badge and your words, no prices (on a fresh phone it switches his app to crew mode: dockets and tickets, no money rooms). A quoter gets the business code + the 🔒 locked book — prices on your paper, can't change a rate. The office or another boss gets the code + the 📚 open book — everything. Someone leaves? There is no lever for that yet — and that is the honest answer. What you handed his phone stays on his phone. The 🔗 join link is single-use and dies in 48 hours, so it cannot be passed on; a 🦺 crew file or a 🔒 locked book already sent cannot be recalled (see the warning below). Being built: take him off the roster and the app mints a new key and re-wraps it to everyone left, so the old copy stops being worth carrying.
The 🔗 join link is the short road: it carries the same words, badge and letterbox as the crew file, minted for ONE operator with his own key. Text it, he taps it, he is on the books. It stops working once he uses it and dies after 48 hours either way. The file stays for a basement with no signal.
Every book and crew file exported lands below — the office's own record of the handouts. No server, no tracking, and sending a NEWER file is how a book gets updated out there.
⚠ A book file is a plain file. Anyone who ends up holding it can open it and read every rate in it, and there is no un-sending one. That is the price of your rates being yours to take anywhere — deal them to people you would hand a printed price list to, and remember the crew file (🦺) carries your words with no prices at all.

🦺 Crew file — words, no prices
🔒 Locked book — his seat stamped
📚 Open book — everything
Seat codes: every phone runs on its own seat code, one per operator — $9.99 each, once.
Tap Buy seats, choose how many at the checkout, and they land here as spares. The next crew file you deal takes one by itself — buy first or name the crew first, either order works.
🪑 Buy seats
Bought on another computer? Paste the codes from your receipt page here — the whole page at once is fine. Name a man to give him a particular seat; leave the name empty and they go spare.
Park
Name him, check his seat, press the button — his locked book lands in your Downloads with the seat stamped in, and his quotes and tax invoices count MF-1, MF-2 … inside it, forever. Nothing to run out. Boxes empty = a plain locked export, exactly as before. A seat is never reused, and your own quote prefix is the office seat, yours alone.
Every quote, invoice and docket you file lands here, newest first — tap a row to open it. ✓ Paid and Correct sit on an invoice’s row; 💲 Invoice it on a docket that came in from the crew. Behind this ⓘ, once papers are here: the export doors (a ledger CSV, Xero by month or financial year), the old drawers, and Delete — a ledger forgets nothing, so deleting is deliberate.
