About this gig
I dont just convert your spreadsheet into a web app I rebuild the business workflow behind it.
If your business currently relies on Excel, Google Sheets, email, or repetitive manual processes, I can turn that workflow into a clean, custom web application your team can actually use.
I can build solutions for:
Orders and inventory
Customer management
Internal dashboards
Approvals and workflows
Forms and data entry
Tracking and reporting
User roles and permissions
Business process automation
Depending on the package, your app can include login, database, dashboards, tables, filters, reports, forms, and structured workflows.
My focus is practical business software with a clear scope, reliable functionality, and an interface designed around your real process.
Please contact me before ordering if your project requires ERP/CRM integration, external APIs, complex migration, or a larger custom system.
Hosting, domains, paid APIs, and third-party software subscriptions are not included unless specifically agreed.

FAQ
1. Can you build the app from my existing Excel or Google Sheet?
Yes. I can use your existing Excel file or Google Sheet as the starting point and rebuild the workflow as a structured web application. I will first review how your data and process currently work so the app reflects the real business workflow, not just the spreadsheet layout.
2. Do you include source code?
Yes. Source code is included unless we agree otherwise before the project starts. You will receive the files required for the scope included in your package or custom offer.
3. Does the price include hosting, domain, or third-party software?
No. Hosting, domains, paid APIs, licenses, and third-party subscriptions are not included unless specifically stated in the offer. I can recommend suitable options and help with setup if needed.
4. Can you integrate my app with another system or API?
Yes, depending on the system and API availability. I can work with external APIs, ERP/CRM platforms, ecommerce systems, databases, and other business tools. Please contact me before ordering so I can review the integration and confirm the scope.
5. Can you migrate my existing Excel data?
Yes. Basic data migration can be included depending on the package. Large, complex, duplicated, or unstructured datasets may require additional work, so please send a sample before ordering.
6. What do you need from me before starting?
Please send your current Excel or Google Sheet, a short explanation of the workflow, who will use the app, the main actions users need to perform, and any examples or screenshots that help explain the process. For larger projects, I may ask a few additional questions before development begins.
7. Can you build a larger custom business system?
Yes. If your project includes multiple departments, complex permissions, integrations, advanced workflows, or several modules, please message me first. I can review the requirements and create a custom offer.
8. Should I contact you before placing an order?
For simple projects, you can order directly if the package clearly matches your needs. For integrations, complex workflows, data migration, or larger applications, please contact me first so we can confirm the scope and avoid unexpected costs.
