Hours in from site.
Invoice out the same day.

Built for subcontractors, not for bookkeepers. Your lads message their hours over or photograph the sheet, you check the figures, and the invoice comes out with CIS already worked out. Free to use.

Four ways to get the hours in

Nobody on site wants to fill in a portal. So they don't have to — every one of these lands as an unchecked timesheet for you to confirm.

📷
Photograph the sheet

A handwritten sheet, a scrap of paper with the days down the side, a client’s own form — or the site signing-in sheet with the whole gang on it. It gets read and the days filled in for you to check.

💬
Message them over

Reply to the daily WhatsApp with 7-4, 07:30-16:00, 8 hours or 8-5 sat. Send it again for the same day and it corrects rather than doubles up.

Email them in

Every client gets their own address. Anything sent to it lands here — a photo of a sheet, or just the times in the subject line.

Type them yourself

Start an empty week and fill it in. Your usual start, finish and break fill the days in one press, then you correct the ones that were different.

Clients with their own paperwork

Most main contractors hand out their own timesheet, and some want invoices on their own form too. Upload a blank of either against that client, once. Filled copies of it are then read against a layout we know rather than cold, which is the difference between a scan that mostly works and one that gets the hours right. Keep as many as you need — a form each for every client, and your own for everything else.

The site signing-in sheet, with everyone else on it

Half the time the only record is the sheet by the gate, with six names on it and yours somewhere in the middle. Photograph the whole page and say who you are billing for — only their rows come through, and the page tells you who else was on there and that they have been left alone. Ditto marks are read as what they mean on a shared sheet: the same as the line above it on the page, in that column — including when the line above is somebody else’s, which is exactly why the second man wrote one.

If it cannot tell whose a row is, it says so and fills in nothing rather than putting one man’s hours on another man’s invoice.

Nothing is ever invoiced straight off a reading. A misread digit off a handwritten sheet is somebody’s wages, so a person confirms every figure first.

Hours by WhatsApp.

A nudge at knocking-off time, to whoever you put on the plan. They reply with their times and the day goes onto that week’s sheet. No app, no login, no account — they need a mobile and nothing else.

Each person can have their own time, their own days, or none at all
Working for more than one agency? Send A, B or C to say which — no letter means the usual one
Reply STOP at any time and the messages stop
Hours logged this way become a timesheet, or go straight to an invoice — your choice, per person

WhatsApp because the thread stays put. If a day’s hours are ever queried weeks later, what was sent and when is still sitting on both phones.

What it costs
£3.50
per person, per month
Running a gang? It comes down:
1–4 people £3.50 each
5–9 people £3.00 each
10–24 people £2.50 each
25+ people £2.00 each

Only for the people you switch it on for. Adding somebody to keep track of their hours costs nothing — the charge is for the messaging.

The document, done properly

Confirmed hours price themselves off your saved rates and come out as an invoice you can send. Overtime, Saturdays and Sundays are called out as their own lines, so whoever is paying can see exactly what they are paying for.

CIS worked out

Deducted from labour only, never from materials or plant. 30%, 20% or 0% depending on how you are verified, and changeable on any one document.

Every kind of document

Invoices, hours invoices, quotes, applications for payment, proformas and credit notes. Each with its own numbering, sequential with no gaps, which is what HMRC expects.

Mileage at HMRC rates

45p a mile to 10,000 in a tax year, 25p after, counted from 6 April across everything already invoiced. Company vehicles claim nothing unless you say otherwise.

Signed off on site

Send whoever supervised the work a link. They see the sheet, sign it with a finger, and you have the signature on file. No account, no app.

Different rates per client

A client can have their own rates, their own numbering, their own mileage — anything you leave blank is simply your own setting, so changing yours still moves them.

Your paperwork, your name

Your logo and details on every document. Raventech shows as a small mark in the footer and nowhere else.

Knowing where you stand

Invoiced, received, still owed and overdue — with owed and overdue counted across everything, all time, never just the period you happen to be looking at.

Who owes you, worst first

The list you work down, with how long each one has been sitting there and what it averages to get paid.

Repeating invoices

Paid on the first Friday and the invoice has to be in the Monday before? Say that, and it prepares itself as a draft on the right day. Nothing is sent without you.

Sent for sign-off automatically

Timesheets and invoices go out on a schedule with the document in the message and a PDF to keep. They sign on a page, and you see who has and who has not.

Hand it to another Raventech account

If the firm you invoice is on here too, swap codes once and you can pass a document straight across instead of both of you typing it.

Free to use.

The invoicing and the timesheets cost nothing. No payment processing and no cut — you raise the document and get paid direct. The only thing you ever pay for is the messaging, and only for the people you switch it on for.
