How to Track Dev Project Expenses Without a Spreadsheet (2025)

You shipped three side projects last year. You're proud of them. But do you actually know how much each one costs you every month?

If you're like most indie developers, the honest answer is: not really. Maybe you have a vague sense that your hosting is "around $20" and your domains cost "something." But the actual number — the total monthly burn across every project — is a mystery buried in credit card statements and email receipts.

Why Indie Devs Lose Track of Expenses

The problem isn't that you're careless. It's that developer expenses are uniquely fragmented. Consider everything that goes into running even a simple side project:

Domain registration — $12/year here, $15/year there. Easy to forget until the renewal email hits.

Hosting — Vercel, Railway, DigitalOcean, AWS. Each with its own billing cycle and dashboard.

SaaS tools — Error tracking, analytics, email sending, database hosting. Free tiers expire. Usage creeps up.

API costs — OpenAI, Stripe, Twilio. Pay-per-use means the bill changes every month.

SSL certificates — Mostly free now, but some setups still cost money.

CI/CD — GitHub Actions minutes, CircleCI credits. Free until they aren't.

Monitoring — Uptime checks, log aggregation, APM tools.

Each expense lives in a different dashboard, bills on a different day, and comes from a different vendor. No single place shows you the full picture.

The Spreadsheet Trap

The first instinct is usually: "I'll make a spreadsheet." And spreadsheets work — for about two weeks.

Here's what happens:

You create a beautiful Google Sheet with columns for service, cost, billing cycle, and project.

You fill in everything you can remember.

You forget to update it when you sign up for a new tool.

Three months later, the spreadsheet is outdated and you're back to guessing.

Spreadsheets fail for expense tracking because they require you to remember to update them. There's no automation, no reminders, no structure that maps to how developers actually think about their projects.

The other problem is categorization. Spreadsheets are flat. But your expenses aren't — they're hierarchical. You have projects, and each project has expenses, and each expense has a category (hosting, domain, SaaS, API). Doing this in a spreadsheet means endless columns or multiple tabs, and suddenly your "simple" tracking system needs its own documentation.

How to Actually Track Dev Expenses

The key insight is that developer expenses should be organized by project, not by vendor or date. When you look at your spending, you want to answer questions like:

"How much does my SaaS project cost me per month?"

"Which project is burning the most money?"

"Am I spending more on tools I'm not even using?"

This means your tracking system needs three things:

1. Project-Based Grouping

Every expense should belong to a project. Not a category, not a date range — a project. This is how developers think about their work, and it's how expenses should be organized.

2. Recurring vs. One-Time Classification

Some costs are monthly (hosting, SaaS subscriptions). Others are annual (domains, SSL certificates). And some are one-time (buying a template, hiring a designer). Your tracker needs to handle all three and normalize them into a monthly burn rate so you can compare apples to apples.

3. Waste Detection

Here's the uncomfortable truth: most indie devs are paying for at least one tool they don't use anymore. Maybe it's a monitoring service for a project you abandoned. Maybe it's a premium tier you upgraded to during a launch and never downgraded. Being able to flag expenses as "unused" and see your total waste is powerful — and a little painful.

The Real Cost of Not Tracking

When you don't track expenses per project, you can't answer the most important question an indie dev faces: is this project profitable?

You might be making $200/month from a SaaS product and feeling good about it. But if you're spending $150/month on hosting, monitoring, email, and API costs, your actual profit is $50. And if you factor in the domain and annual tools, it might be even less.

Without per-project expense tracking, you're flying blind. You might be subsidizing money-losing projects with income from profitable ones and not even know it.

Stop Guessing, Start Tracking

If you're tired of the spreadsheet dance and want a simple way to track every dev expense by project, try Dev Expense Tracker. It's free, works in your browser with no signup, and organizes everything the way developers actually think — by project, with categories, recurring cost normalization, and waste detection built in.

Your side projects deserve better than a forgotten Google Sheet.
