Custom web applications

A custom application.
All your work, finally in one place.

Excel files, long email threads, information typed in twice: we replace them with a web application built around your processes. The proposal becomes an order, the order becomes a project, and everyone knows where each file stands.

Built by Kasvu · The Pavar application

Your team prepares.
Your client approves.

Try the application we built for Pavar: the team prepares the proposal, the client approves it online and specifies their manufacturing choices. Walk through each step, from either side.

01 / PAVAR SIDE

The right products. The right price. No starting from scratch.

Pavar builds its proposal from the products and options connected to its website. Photos, quantities and prices come together in a document ready to share.

↳ The catalogue becomes a sales tool.

What we build

The tool missing between your teams.

We start from the real work. Screens, rules and integrations then follow the way you work, not the way a generic software package does.

01

Proposals and orders.

A proposal built from your products and pricing rules. The customer requests changes or approves online; the order picks up everything, with no re-entry.

Catalogue · Options · Approvals
02

Operations and production tracking.

Every file has a status, an owner and a next step. Your team sees what is ready, what is waiting and what is stuck, without chasing information.

Projects · Work orders · Progress tracking
03

Client and partner portals.

Your customers view their file, send their documents and confirm their choices. Conversations stay in one place, with full context.

Dedicated access · Documents · Approvals
04

Integration with your tools.

Your website, CRM, email or accounting software: the application connects to them. We choose the integration each system allows.

Connections · Imports and exports · Sync
05

Automation of repetitive tasks.

Generate a document, send a reminder, pass information to the next step: clear rules replace the small manual tasks that eat up your days.

Documents · Notifications · Data transfers
06

Centralized data.

The details, decisions and history of every file in one place. Everyone accesses what they need to do their job.

History · Search · Permissions

Case study · Pavar

Hundreds of choices.
One proposal that holds together.

Pavar builds chairs and banquettes for restaurants across North America. Proposals were prepared in Excel, with hundreds of possible choices.

We built an application connected to its catalogue and options. The client receives a link, requests changes or approves. They then specify their manufacturing choices, and the order becomes a production project.

Excel gave way
to a complete workflow.

  • Less time spent preparing proposals
  • Less re-entry between sales and production
  • Less risk of error in the choices passed on

Integrations & artificial intelligence

Keep what works.
Connect what’s missing.

Your application doesn’t have to replace your software. It bridges the gaps between your tools and handles the steps they don’t cover.

01 / YOUR TOOLS

Your current systems stay in place.

Accounting, CRM, email, product catalogue: we check the possible connections from the start. An API, an import or an export is sometimes enough to eliminate double entry.

Your toolsYour applicationYour team
02 / USEFUL AI

AI, where it saves time.

Reading a document and extracting its data, summarizing a file, drafting a reply: we build AI into the tasks where it truly reduces the work, with human review where it’s needed.

Your data and your rules govern every feature.

One team. A clear engagement.

We build it with the people who will use it.

François scopes the project with you and stays involved through delivery. Jihed coordinates the delivery team. Your users try the application at key stages.

  1. 01

    Understand the work

    We look at your files, your tools and the real path of a file. We identify the top pain points, the constraints and what can stay in place.

  2. 02

    Design the first version

    We define the user flows and screens to approve. Scope, integrations and success criteria are set before we build.

  3. 03

    Build and validate

    You see the application take shape. Demos and trials with your users catch gaps before launch.

  4. 04

    Launch and support

    We migrate the data planned in the engagement, train your team and support the rollout. Support and future improvements are agreed with you.

You stay in control

Your application belongs to you.

The code, the data and the access are yours. Documentation, hosting and support are planned in the engagement: your tool can keep evolving with your business, with or without us.

Is this the right time?

Custom software has to solve a real problem.

A custom application is worth the investment when your processes, rules or integrations go beyond what your current tools allow. If existing software does the job, we will tell you from the start.

  • The same information is retyped from one file to another, with a chance of error every time.
  • Tracking a file depends on a few people’s memory or on long email threads.
  • Every new customer adds admin work faster than your team can keep up.

Frequently asked questions

Costs, timelines, ownership: your custom app questions.

How much does a custom application cost?

The price depends on the number of screens, the rules to program and the integrations with your tools. We first define a useful first version, usually delivered in about eight weeks; the proposal sets its scope and price before work begins.

How long does development take?

A first working version is usually ready in about eight weeks, depending on the type of engagement. We deliver in stages: your users try the application before launch, then it evolves with your priorities. The exact timeline is set in the proposal.

How does an application project work?

In four stages: understanding how you really work, designing the first version, building and validating it with your users, then launching it and supporting your team. François scopes the project with you and stays involved through delivery.

Do we need to replace our current software?

Not necessarily. The application can connect to your accounting software, CRM or email through an API, an import or an export, and handle the steps those tools don’t cover.

Why a custom application instead of off-the-shelf software?

If off-the-shelf software meets your needs, it is often the best choice, and we will tell you from the start. Custom development makes sense when the way you work, your rules or your integrations go beyond what those tools allow.

Can you build in artificial intelligence?

Yes, where it cuts real work: reading a document and extracting its data, summarizing a file, drafting a reply. We plan human review where it’s needed and limit access to the data that is required.

Who owns the code and the data?

You do. The code, the data and the access belong to you. Documentation and hosting are planned in the engagement so your application can keep evolving, with or without us.

The first conversation is with François

Show us how you work.

An Excel file, a process that gets stuck, an idea for an application: that is enough to start a conversation with François. Together, we will see what is worth building. The first conversation comes with no commitment.
