WorksDue is a phone app for small subcontractors and firm owners. Log every extra on site — the photo, who instructed it, and the value — so when a contractor won’t pay for the extra work, you’ve got the evidence, not a memory. And get reminded when your retention is due after practical completion, so the money held back doesn’t sit in someone else’s account. No back-office system you’ll never open on site. Just the two things that quietly cost trades money: extras that go unclaimed, and retention that’s never chased.
When the contractor won’t pay for the extra work
It’s the conversation every subbie has had: you did the extra, it was agreed on the spot, and now the final account is being argued down because there’s nothing in writing. Extras die in WhatsApp. A verbal instruction, a quick photo, a “sort it and we’ll settle up” — then the job moves on and the paperwork never catches up.
A variation only holds up if you can show it was instructed and you expected to be paid. WorksDue captures that at the moment it happens — the instruction, who gave it, photos, and the value — so the record exists before the dispute does.
Log every extra before it’s forgotten
Capture extras the moment they happen
Log the instruction, the photos, and the value while you’re still on the job. Nothing gets lost between site and office.
Photo, who said so, value
Mark each extra pending, approved, or rejected — with the evidence attached, not reconstructed from memory weeks later when someone queries the final account.

Get your retention back — don’t let it sit in someone else’s account
Retention disappears on a timer. Money is held back at practical completion, then simply forgotten once the defects period passes — and main contractors rarely release it unless you chase. If you don’t ask, it stays put. WorksDue works out when your retention is due from the contract value and the retention percentage, then reminds you before the deadline — including the second half that falls around 12 months after practical completion, when the job’s long off your radar. You see what’s held, what’s due, and what’s already overdue, per project and across the business.
WorksDue keeps the record and the reminder so you can claim on time — it doesn’t chase the money for you, it makes sure you never forget to.
How the WorksDue app works
Three habits. No training course.
1. Create the job. Add the project, the contract value, and the retention percent. That’s the setup.
2. Log extras as they happen. Photo, who instructed it, value — pending, approved, or rejected, with evidence attached rather than a later guess.
3. Mark practical completion, then claim on time. WorksDue schedules the retention date and reminds you before it’s due, so the money held back actually comes back.
Who WorksDue is for
If you run a small gang or a small firm, this is the list.
Small subcontractors. You do the extra work. You need a record before the conversation moves on — and a reminder when the money held back is actually due.
Small firm owners. A handful of live jobs, not a commercial department. One place for contract value, extras, and retention instead of notes, photos, and a folder you forgot about.
Is WorksDue free?
Core tracking will be free for a small number of live projects, so you can log extras and stay on top of retention without paying anything. A Pro plan is planned for people running more jobs at once, with export and a yearly overview across the business.
Frequently asked questions
The contractor won’t pay for extra work I did — what can I do?
The work usually has to be shown to have been instructed, with you expecting payment — a verbal “just do it” is hard to prove months later. The strongest position is a record made at the time: what was asked, who asked, the value, and photos. WorksDue is built to capture exactly that on site, so an extra is evidenced before it’s ever disputed.
How do I get my retention back?
Retention is normally released in two stages — half at practical completion, the rest at the end of the defects period (often around 12 months later). You generally have to request it in writing rather than wait for the contractor to volunteer it. The catch is remembering the second date a year on. WorksDue tracks both dates per job and reminds you before each one so the claim doesn’t slip.
How long do I have to claim retention after practical completion?
It depends on your contract, but the final release is commonly due around 12 months after practical completion, once the defects (rectification) period ends. WorksDue works this out from the date you enter and nudges you ahead of it.
What counts as a variation or an “extra”?
Any work beyond your agreed scope — extra tasks, changed specs, additional materials instructed on site. If it isn’t recorded with evidence at the time, it’s easy to lose when the final account is settled. WorksDue lets you log each one with a photo, the value, and who instructed it.
When does WorksDue launch?
Planned for Q2 2027 on the App Store and Google Play. Join the waitlist and you’ll get one email the moment iOS and Android are live — no drip campaign, and you can unsubscribe or write to support@worksdue.com any time.
Does WorksDue work on iPhone and Android?
Both — the same product on iOS and Android. We’ll email you when the store listings go up.
What happens if I get a new phone?
Your projects, extras, and photos back up to your WorksDue account. Sign in on a new phone and they restore, so you’re not re-typing a year’s work. A working copy also stays on the device you’re using, so you can still open jobs on site.
