What SiteBook does, in detail

SiteBook is one operations system for a contractor that executes work on site and trades construction chemicals: daily progress reports, attendance, BOQ and running bills, stores, site cash, a director dashboard and a trading desk. Every feature below runs in the live demo above with sample data.

Daily progress reports from the site

The site engineer files one report per site per day from a phone: quantity done against each BOQ line, labour by trade, material used from the site's own stock, weather, issues and up to six photos, shrunk on the phone before upload.

The project manager approves it or sends it back with a note. Only approved work counts toward the site's progress, so the progress bar on every site is something the office has checked.

Attendance marked on site

Each site has its crew. The engineer marks present, half day or absent with one tap per person, or "rest present" for everyone else, and can pull a worker in from another site for the day.

The daily report's labour section fills itself from attendance by trade, and labour cost on the dashboard comes from the same marks.

From BOQ to running-account bill

A site's contract BOQ is copied from the client's accepted quotation or entered line by line. Once work is reported against a line, only its quantity can change, so past bills keep their meaning.

Measurements are recorded against the BOQ (or filled from approved work), and an RA bill takes everything not yet billed: previous, this bill and up-to-date quantities per line, CGST and SGST or IGST, amount in words, as a PDF. Bills move from draft to submitted, certified and paid, and paid goes into the cash book.

Stores for the godown and every site

Material arrives from suppliers into the godown and is transferred to sites; each site holds its own stock, and material used is taken from it on the daily report. Nothing can be sent or used that is not there.

The daily stock report has the same columns as a stores register kept in Excel: opening, receipt, dispatch and closing per material, for one location or all of them, for a day or a date range, as CSV or print. Materials below their minimum at the godown are flagged.

Site cash, accounted for

The office gives each site's in-charge cash; it is recorded against the site and as cash out in the finance book at the same moment, so the two always agree.

Spends are recorded from a phone with what they were for and a photo of the receipt. A site cannot record more spending than the cash it holds, and sites running low show on the dashboard.

Is each site making money?

Cost to date is material used on site, labour from attendance and wages, and site cash spent. Against the value of approved work it gives each site's margin so far; scaled to the whole contract, it projects where the site will finish against its estimate.

Sites are marked on track, over budget or losing money, next to a short list of what needs attention today: reports waiting for approval, sites low on cash, materials below minimum.

Trading construction chemicals

An inquiry becomes a quote where each product shows godown stock and the last purchase rate; a margin percentage sets the selling rate. The quotation PDF never shows cost or supplier.

The customer's PO is checked on six points, then the order is held until the advance is in or until it fits the customer's credit limit with nothing overdue. It is fulfilled from stock, through the godown, direct from the supplier or as an SEZ supply under LUT, invoiced with GST, and the e-way bill checklist shows what is still missing.

Invoices and the finance book

Trading invoices and RA bills carry HSN or SAC codes and the right GST split, and download as PDFs.

Customer receipts, supplier payments, advances and site cash all land in one cash book. Site engineers never see company finances or the dashboard; this is enforced on the server for every request, not just hidden on screen.

Connects with the tools a contractor already uses

Ahrom Labs has built each of these connections for clients before. Two run in this demo; the rest are set up for each company with its own accounts.

  • WhatsAppSet up per company

    The director gets each evening's approved daily reports as one message; customers get quotations, RA bills and payment reminders on WhatsApp; a site engineer can send photos straight into the day's report.

  • TelegramSet up per company

    Each site has a group: the approved daily report, low site cash and stock below minimum are posted there, so the site and the office see the same thing.

  • TallyPrimeSet up per company

    Invoices, RA bills, supplier receipts and site expenses go into Tally as vouchers with the site as the cost centre. Tally stays the statutory book; the app keeps project cost.

  • E-way bill (NIC)In this demo

    The checklist in this demo shows what each dispatch still needs. Live, the e-way bill is generated from the company's own NIC registration, or handed to accounts to file in Tally.

  • GST returnsSet up per company

    GSTR-1 figures come from the invoices and RA bills already in the system, with HSN and the CGST / SGST / IGST split as billed.

  • Google MapsSet up per company

    Site locations and road distance from the godown, for transport costing and the e-way bill; attendance can record where it was marked.

  • GmailSet up per company

    Quotations, RA bills and invoices emailed to the customer from the app, with the PDF attached.

  • Cloudflare storageIn this demo

    Site photos, receipts and documents stored safely and shown inside the app.
