How it works

From contract to payment, a record both sides recognize at every step.

Keep the tools you already use. Bring only what needs the other side's sign-off into KIDGE.

  1. Upload a contract. Deadlines land on the timeline.

    KIDGE pulls every milestone, billing window and payment due date from the contract. You review and confirm. Contract deadlines such as warranty and retainage release get a reminder before they come due.

  2. Submit work. The owner approves online.

    Send documents and site photos for review together. Owners and their reps join free and approve online. Once approved, the record is locked for both sides.

  3. From pay app to payment, see where it's stuck.

    Pay apps link to approved work. The owner's payment and your receipt are both time-stamped, and billing deadlines and overdue payments are flagged right on the milestone.

    Contractor ↔ Owner

  4. Build a track record you can share.

    Every milestone both sides approved becomes verifiable proof of performance. When you bid next, share it with the new owner.

Frequently asked questions

The questions we hear most, answered in one place.

What companies is KIDGE for?

KIDGE fits teams that work across companies and regularly deliver, invoice, and get work signed off — interior fit-out, construction contracting, equipment installation, systems integration, and the like. If your projects need a verifiable record of what was delivered and approved, KIDGE earns its keep.

Can KIDGE replace my project management tool?

KIDGE isn't here to replace the PM tool you already know — it fills the piece those tools miss: cross-organization confirmation, delivery evidence, and a solid basis for billing. Keep working the way you do, and keep the deliveries and sign-offs that actually matter in KIDGE.

What's the advantage over Excel / LINE?

Excel can be edited and LINE threads are endless — when something goes wrong you can't produce proof the other side agreed. Every KIDGE entry is mutually confirmed, timestamped and locked — the difference isn't how it looks, it's whether you recover that payment when things go sideways.

What if the owner or supervisor won't come confirm?

Confirming is free for owners and supervisors. After a one-time sign-up they confirm online, with nothing to install. Most owners and supervisors are glad to, because a mutual record protects them too. Even if they don't come right away, your submission and its timestamp are recorded — keeping proof that you proactively asked.

Is setup complicated? How soon can I start?

No rollout, no training. Upload one contract and KIDGE lists the deadlines worth tracking — you can start the same day. Keep working the way you do now; you're just moving confirmation and evidence online.

Do clients and external collaborators have to pay?

No. Only you (the contractor) pay; owners, supervisors and external collaborators confirm for free — we don't want 'who pays' getting in the way of you getting your evidence.

Is my data secure?

Your project, delivery and client data belongs only to you, encrypted in transit and at rest. We never sell it or leak anything identifiable; only fully de-identified data that can't be traced back to you or your clients may be used to improve KIDGE. Data sovereignty stays with you.

Can I try it first?

Yes. Sign up and create your organization to start a 14-day free trial, no card required. You can invite your owner and vendors during the trial; they join free and never take a seat.
