I'm building an aggregated sales reports tools for makers

Dear Indie Hackers,

I built many side-projects. Each of them are meant to:

• Solve one of my problems, and will be used at least by me (this follows "Getting Real - Basecamp" and "Make - Peter Levels" philosophy)
• Learn something new (a new tech, new architecture, new skill, anything)
• If possible generate some income

I built many projects last year, including 3 mobile apps and I started to face a two main problems:

• Google Play's reports displays your sales but not your earning revenues (after their fees), Apple's one is better but not very easy to use
• For accounting purpose I need to manually create "Reverse charge invoices"

So I decided to build Revenual (work still in progress).

Revenual aggregates sales data from Google Play, AppStore (and hopefully in the future: Stripe, Paypal, Google Adsense) and generates reports and the reverse charge invoices.

User flow

1. Create an account & log in
2. Connect your accounts: Google Play, AppStore
3. Choose a month and a year and click generate (this will be automated in the future)
4. Wait a few seconds and see your detail sales report

What is in the report ?

• The total earnings (Unit sold | Sales | Fees | Taxes | Earnings) from all the platforms / provider
• The earnings (Unit sold | Sales | Fees | Taxes | Earnings)
  • per platforms / provider
  • per product sold
  • per country
• Pie charts to see the repartition

How much will it cost ?

I am thinking to put an initial price of 38 USD / month.
The first report will be free. To generate more reports you will need to pay.

Current status

The core features (report generation & invoice generation) are developed, I need to implement and nice UI & UX.
I expect to release a first version by the end of January / beginning of February

Tech stack

As I said above, when I build a new project I try to learn new skills, I wanted to build an app with a SOLID architecture, use design patterns and use TypeScript. So I ended up with this stack:

• NodeJS / Express.JS / TypeScript
• MongoDB

In the current version the server is rendering the pages.

In the future reports will be loaded asynchronously trough background jobs. The frontend may later be rebuilt as a SPA and the backend turned to an API only.

My questions

1. What do you think of the pricing ?
2. If you have a similar problem, and are interested in using my app, let's talk!
3. Feel free to send critics, feedback, every comment is completely welcomed.
