São Paulo, Brazil
- Scope, timeline and price fixed before development
- Working software every 2 weeks
- You decide before paying anything
- Your company owns the code, by contract
It's a good fit when…
- A spreadsheet has become your company's system, and only one person knows how to use it.
- Orders, customers and deadlines are scattered across emails, notebooks and chats.
- Off-the-shelf software doesn't follow your process, so your team keeps working around it.
- To see how operations are doing, someone has to put a report together by hand.
- Customers call to check on their order, and someone drops what they're doing to answer.

Examples of what we can build
Custom ERP: financial and operations management
Accounts payable and receivable, cash flow, purchasing and reports in one place, with no side spreadsheets.
Custom CRM for your sales and service teams
Contacts, deals and each customer's history, visible to everyone in sales and customer service.
Inventory and orders
Incoming, outgoing and reserved stock tied to orders from customers and sales reps, with each customer's price list, so you know what's available before making a sale.
KPI dashboards
Sales, inventory and finance on an up-to-date dashboard, so you can decide without waiting for the month-end close.
Admin panel
Where your team enters data, approves requests and sets up how the system runs day to day.
Customer portal
Orders, invoice copies and status in a space just for your customers (the reseller who calls today to ask about an order, for example), without the back-and-forth over email.
Training and course platform
Courses and learning paths for your team or your customers, with access control and progress tracking.

How web application projects work
Working software every 2 weeks
Every 2 weeks, a working part of the system for your team to use.
Support and continuous improvement
Ongoing
If you'd like, we stay on for support and continuous improvement, so the system keeps up with your operations.
What gets pinned down before development
- Which processes come first
- Who can access what: roles and permissions
- The reports your managers can't do without
- Which integrations with other systems are needed
Where you make the call
You don't commit to the whole project blind: no paid stage starts without your go-ahead.
With the written feedback in hand, you decide whether to go ahead. The Discovery Sprint, when it's needed, is free.
With the timeline and price fixed in the plan, you decide whether to move into development.
What drives the price of a web application
Modules and processes
Every process you add comes with its own screens and rules. More processes, more scope.
User types and permissions
When managers, sales reps and customers see different things, each role has to be designed and tested.
Business rules and calculations
Commissions, customer-specific pricing, taxes, exceptions: the more rules unique to your business, the more work it takes to get every case right.
Integrations with other systems
Connecting to the system you already use, your online store or your payment providers depends on what each of them allows.
Data from spreadsheets or legacy systems
When historical data needs to come along, it has to be cleaned up and checked before it goes in.
Reports
Every report depends on reliable data behind it. The more reports, and the more data sources each one pulls together, the bigger the effort.
We look at how each of these applies to your project, then fix the timeline and price before development starts, without charging anything until then.

Questions about web application projects
Custom software or off-the-shelf?
If off-the-shelf software fits your process, it's usually the cheaper route. Custom makes sense when your process is what sets your company apart, or when an off-the-shelf tool forces your team to work around it. The free assessment helps you decide.
Do I need a technical background to hire you?
No. You describe the problem in plain business terms, and together we turn it into a prioritized scope: what comes first and what can wait.
Can we start with just one part of the system?
Yes. The scope is prioritized with you before development, and the working software you get every 2 weeks follows that order: whatever matters most to your operations comes first.
How much does a custom web application cost?
It depends on how many processes are included, the access roles, the business rules, the integrations and the reports. The price of your system is fixed before development starts. If you already have a budget in mind, tell us in the assessment: the prioritized scope shows what fits within it.
Do I pay anything before development?
No. The assessment and, when it's needed, the Discovery Sprint are free. The paid stages are development, with the scope, timeline and price fixed before it starts, and ongoing support, if you want it.
How long does it take to build a web application?
The timeline is fixed before development starts, along with the price, and it depends on the scope. If the system has to be live by a certain date, bring it up in the assessment. The date goes into the plan, so before we start, you'll know what can be ready by then.
How do I know the project won't stall halfway through?
Projects usually stall when the budget runs out before the software is ready, or when nobody sees anything working until the end. Here, scope, timeline and price are fixed before development starts, and every 2 weeks you get a working piece: if something goes off track, you notice early, not just at the end. And the code built for the project belongs to your company, by contract: if you ever need to move to another vendor, it stays with you.
What if I need to change the scope mid-project?
You get working software every 2 weeks so you can spot early on what needs to change. If a change affects the scope, we agree on a revised scope, timeline and price with you before we continue.
How do I keep track of progress?
By using the software itself, no technical knowledge needed: every 2 weeks you get a working piece of it to use and give feedback on.
Does my company own the code?
Yes. The code built for your project belongs to your company, and that's written into the contract. If you ever want to continue with another vendor, the code is in your hands.
Will you sign a non-disclosure agreement (NDA)?
Yes. If your project calls for confidentiality, we'll sign the agreement before you share the details. Just ask on WhatsApp or by email at comercial@lemamon.dev.
