Money and accounting in the product
Payments, balances, stock or bookings, where a data mismatch means direct losses.
PostgreSQL
An open-source object-relational database with strict transaction support. We choose it when a product has complex logic, many relationships and reports.
WHY WE CHOOSE THIS
A mismatch in payments or stock hits both revenue and reputation. PostgreSQL keeps every transaction consistent, and complex reports can be built directly from live data.
Complex relationships between data
Customers, orders, roles and contracts are linked, and the business needs accurate reports.
The product is built to last
The business is building a long-term platform and does not want to change databases at the first load increase.
SaaS platforms and client areas
A relational model with roles, access rights and transactions for customer data.
Fintech and accounting systems
Transactions with isolation levels, so balances and payments always match.
Services with geodata
The PostGIS extension for distance search, delivery zones and maps.
Analytics and reporting
Complex queries, views and JSONB for reports without exporting to spreadsheets.

Why PostgreSQL and not MySQL?+
It depends on the product. For a typical CMS site the difference is small. We choose PostgreSQL when there are many relationships between data, complex reports, geodata or a need to store flexible JSON fields next to regular tables.
Will the database keep up as the business grows?+
Yes, if the structure is well planned. PostgreSQL handles large data volumes and supports read replicas and table partitioning. Bottlenecks are usually in queries and indexes, so we build them into the architecture from the start.
Can data be moved from our old system?+
Yes. We move data from other databases, Excel or legacy CRMs with integrity checks and a test run, so no orders or customer history go missing after the switch.
Do we have to pay for a PostgreSQL license?+
No. PostgreSQL is open source with a free license, including for commercial projects. The only costs are the server or a managed cloud service, and they depend on data volume and load.
Data is the foundation of a product, and cutting corners on it is expensive.
PostgreSQL development at GVSPACE is the foundation for SaaS platforms, client areas, accounting and fintech services where data integrity is critical. We design the schema around business processes, set up indexes, replication and backups, and use JSONB and PostGIS where they add value. We combine PostgreSQL with Node.js, Redis and cloud infrastructure, so the product can grow without rewriting the database.
