Renovation under control

Estimate, stages, payments and a chat with the crew in one app. Payment is tied to a signed-off stage.

MVP, preparing a closed test

Built: versioned estimates, stages with sign-off and photo evidence, stage payments, disputes and variation orders, chats and a notification centre, client, contractor and guest roles, project participant management, an offline mode with an action queue. Receipt and self-employed status checks via the Federal Tax Service are built and covered by tests; live verification awaits keys. Scope of work: section 07.

Summary

  1. The estimate drifts from actual costs, and overspend surfaces only at the end.
  2. The contractor’s status goes unchecked, and no one is accountable for the result.
  3. Renova brings together the estimate, stages, payments and chat. Every action recalculates the figures instead of relying on what each side remembers.

01 — The problem

Renovations run on chat threads, and no one is accountable

The economics of a renovation are never in one place: the estimate in a file, the conversation in a messenger, the receipts in a pile.

  1. The estimate drifts from actual costs

    The estimate is kept apart from purchasing and payments. The gap builds up unnoticed and comes to light at the end.

  2. Payment is not tied to results

    Payment follows a verbal agreement rather than a signed-off stage. What exactly was paid for cannot be checked later.

  3. The contractor’s legal status is unconfirmed

    Self-employed or sole-trader status is taken on trust and, as a rule, not checked at the time of payment.

  4. Whether a stage is finished is a matter of trust, not fact

    The crew and the client mean different things by “done”, and there is no shared confirmation. Photos, if any, stay in a phone gallery, not linked to a stage or date.

Outcome: the client learns the real cost of the renovation only after the money has been spent.

02 — The principle

Every action recalculates the figures

  1. The estimate is a state, not a document

    Every change to the estimate is saved as a new version. You can see what changed, when, and why the plan departed from actual costs.

  2. Payment is tied to sign-off

    A stage payment is confirmed only after sign-off, with photo evidence and confirmation from both sides.

  3. Checks go to official sources

    Receipts and self-employed status are checked via the Federal Tax Service, not on the contractor’s word. The check is built and tested; live mode awaits keys.

03 — System class

A place between the group chat and the contractor’s accounting system

Private renovations are run in one of three ways: a spreadsheet with receipts, a group chat with no single version of the estimate, or the contractor’s own accounting system (1C, a site manager’s software), closed to the client. None of them shows the client the full economics of the project.

The Renova column shows the intended scope; readiness is described in section 07. None of the three usual methods checks the receipt or the contractor’s status.

04 — Scope

From estimate to signed-off result

Each step builds on the last: a stage payment cannot be confirmed before sign-off, and the estimate cannot be changed unnoticed.

  1. Estimate
  2. Version approval
  3. Work on the stage
  4. Photo evidence
  5. Sign-off
  6. Payment
  7. Next stage
Exhibit 2. System modules and the decisions they cover
Estimate Norm-based line items, versions, plan-versus-actual comparison
What the renovation should cost and what it includes
Changes to the estimate show at once, not after an overspend
Work stages Sign-off, photo evidence, links to estimate line items
What is done and has been signed off by the client so far
A dated photo settles a dispute over completion, not one word against another
Money Stage payments, receipts, self-employed status via the Federal Tax Service
Whether it is safe to pay for this stage and this contractor
Payment is tied to a signed-off stage, and the contractor’s status is open to checking
Conversation Discussion tied to a specific stage rather than a general chat
Which stage the conversation is about
Conversations do not drown in a general feed or drift from the work actually done

05 — Roles

Client and contractor each get their own screens

The client and the contractor see the same site, but each sees their own part.

  1. Client

    Sees the whole estimate, its versions and deviations, stage status and payment history. Signs off a stage or rejects it with a comment.

  2. Contractor or crew

    Runs their own area: photographs the stage, requests sign-off and confirms receipt of payment.

  3. Renovation company

    Tests the approach across a portfolio of sites: several estimates and crews in parallel.

06 — Interface

What it looks like

The screens are captured from a working build. The phone comes first: renovations are run on site, not at a desk.

08 — Involvement

Ways to get involved

Client
You run your own renovation in the app and tell me what is missing: on a real site, not in a demo.
Contractor or crew
You run a live site: estimates, schedules, sign-off. You pass on feedback as the work goes.
Renovation company
You run a portfolio of sites: several crews and estimates in parallel.

I show the system design and the roadmap in person, once a non-disclosure agreement is signed.

09 — FAQ

Frequently asked questions

How does this differ from a spreadsheet and a messenger chat?
It links the estimate, the stage and the payment. Payment is tied to a signed-off stage, and the estimate changes through versions.
How is the contractor’s legal status checked?
Via the Federal Tax Service: the receipt and self-employed status are checked at the official source, not on the contractor’s word. The code and tests are ready; live verification awaits keys.
Do I have to move the whole renovation into the app at once?
No. Start with one stage or one estimate and run the rest as you usually do.
What happens if the connection is lost on site?
Actions go into an offline queue and are sent once the connection returns; stage sign-off and stage photos, among others, work this way. Idempotent replay after a lost server response is still being finished.
How is Renova related to Syntha and ChatX?
It is not directly related: Renova is a separate product outside the fashion industry. The principle is the same: decisions rest on data, not on memory.
Who pays for the app, the client or the contractor?
I will set the payment model after the pilots: the side that gains more on site should pay.
Can the client change the estimate alone, without the contractor’s agreement?
Once a contractor is appointed, the estimate is locked on the contractor’s proposal with the client’s confirmation. After that, changes are raised as variation orders that both sides agree; every version is visible to both.
Is a demo possible?
Yes, on the working build.
