Custom Software or SaaS: How to Decide in Recife

When to build custom software in Recife and when it makes sense to use SaaS. Objective decision criteria for growing companies.

The right question isn't "custom or SaaS". It's: where is my competitive advantage? Software that sustains a competitive advantage cannot be the same as a competitor's. Everything else is a commodity - and SaaS is cheaper.

When SaaS is the right answer

Payroll. Tax issuance. Standard CRM. Email management. Everything the market has already solved, with clear regulations and little differentiation possible. Paying a monthly fee and using what the entire industry uses is the financially correct decision.

When custom software is justified

  • The process is the product: your company charges (or gains efficiency) for how it executes the work. SaaS forces you to execute like everyone else.
  • Complex integrations with legacy systems: SaaS offers APIs, but rarely accommodates the necessary depth of integration.
  • Volume and unit cost: at high scale, monthly per-user fees become more expensive than in-house development in three to five years.
  • Total data control: regulated sectors (health, finance, legal) often require sovereignty that SaaS does not provide.
  • Defensible competitive advantage: if a competitor can buy the same SaaS, there is no advantage.

The hybrid model that works

Mature companies in Recife combine SaaS for commodities (finance, HR, email) with custom systems for the core business. Integrated via API, they form a coherent and economical architecture.

Real cost of custom software

Focused MVP: R$ 80k to R$ 250k. Complete corporate platform: R$ 300k to R$ 1.5 million. Annual maintenance: 15% to 25% of development cost. These numbers are daunting until compared with five years of SaaS fees for a large team - generally, the calculation reverses.

How to avoid the worst of both worlds

Don't custom build what SaaS solves well. Don't force SaaS into what defines your advantage. Wrong decisions in both directions are costly: unnecessary custom software wastes capital; forced SaaS wastes opportunity.
