The questions that come up before anybody buys.

Your accounts stay where they are. We do not replace Tally or your ERP and we do not ask you to. When a quotation is won, the app exports it in a format your accounts software can import, so nobody retypes line items. If you use a system we have not exported to yet, send us one sample import file and we will add it.

Yours. Export everything any day. If you stop paying, the app goes read-only. Nothing is deleted.

Halcyon Crew installs to the home screen and opens without a signal once it is installed, and shows you what it last loaded. Sending a check in still needs a signal, and a check in typed without one is not held for later: it fails, and it has to be typed again once the phone is back in range.

Yes, for what it does, and we hardened it rather than replacing it. Your supervisor is standing in a warehouse with one hand on a phone, and an email and a password there is how you end up with one login shared by six people, which is the thing that actually destroys a record.

So: the table the PINs sit in cannot be read with the key the app ships with, and every sign-in check runs inside the database rather than in the browser. Two people can never hold the same PIN; the app refuses it. The owner can change somebody’s PIN or switch them off from inside the app the day they leave, without ringing us. Repeated wrong PINs lock that PIN out for a while, so nobody can sit and work through the possibilities. And a PIN only ever opens the field app: your rate card, your quotations and your customer list are a separate system with a separate sign-in, and a field PIN cannot reach them.

Halcyon Quote needs Chrome 108 or later, or Safari 15.4 or later, which on an iPhone means iOS 15.4 or later. On a laptop or desktop, a current Chrome, Edge, Safari or Firefox. It reaches the server every time it is used, so it wants a 4G or Wi-Fi connection whenever it is open.

Halcyon Crew needs Chrome 111 or later on Android 8 or later, on a phone with 2 GB of memory or more, or iOS 16.4 or later, which is an iPhone 8 or newer. On a laptop or desktop, a current Chrome, Edge, Safari or Firefox. Chrome updates itself from the Play Store, so it is the Chrome version that decides this and rarely the Android one.

No, and it is two separate steps. First, a language model (we use Claude) reads your supervisor’s check-out note, including Tamil-English shorthand, and pulls out only the measured quantities: 400 sqm primer, 250 sqm top coat. It does not decide the percentage. Second, the app does the arithmetic in code, against the site’s recorded floor area, stage by stage, weighted by area. That is why the bar and the written explanation can never disagree with each other. Progress never moves backwards unless someone marks the work as rework. And if a site’s floor area has not been entered, the app says the percentage cannot be worked out and asks you to add the area, instead of inventing a number. Every assessment shows its working on the ‘How is this worked out?’ page. Open one and check it against your own measurement.

Each person has their own PIN; the owner can change or switch it off. Salespeople see their own quotes, the owner sees everything, and only the owner changes rates or bank details.

One contracting company, in industrial flooring. Both apps were built for that business and both have run inside it every working day since the middle of 2026: 171 quotations under their own serial numbers, and 487 site visits across 124 sites with 18 supervisors active in the last thirty days, counted on their systems on 1 September 2026. We do not name them on this page, and we would not name you on it either.

If you want to see it working rather than read about it, try both apps on sample data from this site. In the scoping call we walk you through them for your own kind of work.

Yes. Try both apps on sample data from this site any time. In the scoping call we walk through them for your kind of work. Once you sign, setup builds them on your rate card and letterhead, and the first real quotation you send is the finish line.

Only on a renewal date. On Yearly, your price is fixed for the whole year you have paid for. On Monthly, we will never change your price without at least 60 days’ written notice, and never by more than 10 percent at one time, and your first twelve months are fixed from the day you start. If you do not want the new price, you stop on that date and take all of your data with you.

In advance, at the start of each period. We send a request for payment 14 days before the due date, showing the amount, the GST and the period it covers, and you pay it by bank transfer or UPI to the account on it, or from a payment link we send on WhatsApp if that is easier. We do not take cards and we hold no mandate on your account, so no money ever leaves your bank without you sending it.

The GST tax invoice follows the payment: we raise it when the money reaches us, within two working days, and send it to the email address on your order. If your accountant needs a document before you pay, ask and we will send the receipt voucher or advance document. If you deduct TDS, deduct it on the value before GST and not on the GST itself, and send us the certificate when you file; a payment short by nothing but a correct TDS deduction is a full payment here.

Clause 4 of the agreement

You get three days of grace. If the money has not reached us on the due date, the 23rd, the 24th and the 25th are yours if the due date was the 22nd: nothing changes in the account, nobody is switched off, nothing slows down and no late fee is added.

If it still has not arrived by 11:59 pm on the third day, the account goes read only that night. Everybody can still sign in. Every quotation, every site record, every photograph and every export can still be opened, read and taken away, and the Excel export still runs in full. What stops is new writing: in Halcyon Quote, no new quotation and no amendment; in Halcyon Crew, nothing can be changed from the office, so no site, no crew, no stock list and no issue can be added or changed. Your supervisors are not affected. They keep starting the day, checking in and checking out, and they are never shown an amount, a due date or anything at all about it. Nothing is deleted, at any point.

When the payment reaches us we switch it back on within one working day, and the same day if it arrives inside working hours. There is no reactivation fee and no back-charge. Paying late costs you the days you could not use, and it never moves your renewal date. If you know a payment is going to be late, tell us in writing before the due date and we will hold the read only until the day you name.

Clause 5 of the agreement

About ten working days from the day we receive your setup pack. Your first real quotation sent from the app is the finish line.

Online. In Chennai, in person is possible. No visits to your sites.

Halcyon Quote is flat per company, with no charge per user. Crew is priced by field users: the supervisors who check in on site. Owners, managers and office staff are not counted. Up to 25 field users: Rs 7,000 a month or Rs 70,000 a year. 26 to 50 field users: Rs 9,000 a month or Rs 90,000 a year. More than 50: we quote. Crossing a tier mid-period costs nothing until your next renewal.

Yes to each. Square feet or square metres, as many brands as your rate card carries, and the GST split follows the site’s state.
