Every job — from first call to paid invoice.
Worksum is Pixrweb's job-management platform for UK trades — electrical, fire & security, plumbing and maintenance. It schedules and dispatches the work, sends it to engineers on a field app that runs offline, captures labour and materials as they happen, and turns a finished job into a VAT/CIS-ready invoice — with the compliance certificates to match. Transparent per-seat pricing, no lock-in, your data always exportable. Worksum is in beta and we're onboarding early firms.
One workspace for the whole job — office, field and customer, all on the same live data.
One connected workflow — not ten apps.
Worksum replaces the pile of spreadsheets, a separate diary, a timesheet app, a certificate template and an accounts package with one calm workspace built for how trades actually run.
Schedule & dispatch
Plan the week on a board or calendar, assign the right engineer, and send the job to their phone — with route ordering and the site's access notes attached.
A field app that works offline
Engineers get their day's jobs, start a timer, log materials, snap photos and capture a signature on site — even with no signal. It syncs when they're back in range.
Clock in on a tablet
Put Worksum on a tablet in the office or van and the crew clock into a job, travel or a break with a PIN. Hours flow straight into timesheets and job costing.
Time → costing → invoice
Labour and materials roll into live job costing, so you see margin as the job runs — then one click turns a finished job into a UK-compliant invoice.
Compliance built in
EICR and fire/security certificates, RAMS and weekly vehicle checks — generated on your letterhead, stored against the job, and shared with the customer.
A portal for your customers
Clients see their quotes, jobs, certificates and invoices on your branded portal — accept a quote, pay online, report a fault and leave a review.
From first call to paid invoice.
The whole job on one thread — quote, schedule, do the work, get paid — with no double entry between them.
Quote & win
Send a tidy quote; when the customer accepts, it becomes a job — no re-keying, linked back to the estimate.
Schedule & dispatch
Drop it on the board, assign an engineer, and it lands on their offline field app with the site details.
Capture on site
Time, materials, photos and a signature — captured on the job, offline-first, feeding live job costing.
Invoice & get paid
One click turns the job into a VAT/CIS-ready invoice; the customer pays on the portal. Certificates issued to match.
Made for the people on site — not just the office.
The crew get a field app that runs with no signal and a tablet clock-in station that's a proper step up from a paper sheet — clock into a job, travel or a break, and the hours land in timesheets and job costing automatically. Travel paid, breaks unpaid, exported clean for payroll.
- Offline-first: works down a plant room, syncs when it's back in range
- Clock into a job, travel or break — hours feed costing & payroll
- Photos, signatures and materials captured against the job
- Time flows into timesheets you approve and export in one click
Gets construction billing right.
Most job tools stop at net and VAT. Worksum understands how the trade actually gets paid — so CIS, the VAT domestic reverse charge and retention are worked out from the job's labour and materials and on the invoice before it goes out.
- CIS deducted from the labour element (20% / 30%)
- VAT reverse charge with the HMRC wording
- Retention withheld and tracked per job
- Two-way Xero sync so it's in the accounts too
The whole operation, in one place you actually own.
Fair per-seat pricing with a 14-day trial and no card up front, no setup project, and a full export whenever you want it — your data is never held hostage.
