Firebase Cost Estimation

For 1 Admin Dashboard and 2 Store Branch POS terminals, Firebase is generally inexpensive. The actual cost depends on how frequently your app reads and writes data, the amount of storage used, and the number of active users.

Firebase Service	Typical Usage	Monthly	Yearly
Authentication	User Login	Free	Free
Cloud Firestore	Inventory, Sales, Customers	$0 – $5	$0 – $60
Cloud Storage	Product Images & Receipts	$0 – $2	$0 – $24

Typical Small Business Scenario

For a setup with:

1 Admin Dashboard
2 Store Branch POS Devices
5,000–20,000 Transactions per Month
Hundreds of Products
Real-time Inventory Synchronization

The expected Firebase cost is typically around ₱300–₱800 per month, or roughly ₱3,600–₱9,600 per year.

What Increases the Cost?

High number of Firestore document reads
Large image uploads
Frequent Cloud Function executions
Many simultaneous users

Cost Optimization Tips

Use real-time listeners only when necessary.
Paginate sales history instead of loading all records.
Cache product and inventory data locally.
Compress uploaded images.
Optimize Firestore queries.

Recommendation

For a business with 1 Admin and 2 Store Branch POS terminals, Firebase remains a cost-effective backend solution. Annual costs are typically well below ₱10,000 when the application is designed efficiently.
