Rule of Thumb

If you have $25K+ to invest and your process is unique (no SaaS fits), custom makes sense. Otherwise, try Airtable, Notion, or Zapier first. Many small businesses outgrow no-code before they need full custom — and that's fine. Validate with cheap tools, then invest when the pain is real.

When Custom Makes Sense for Small Business

• Your industry has unique workflows (healthcare scheduling, logistics, specialty retail)
• You're replacing spreadsheets that 3+ people use and errors are costing you
• You need to integrate 2+ systems (CRM, accounting, inventory) and no-code can't do it
• The software is your product (SaaS, platform) — you're a tech-enabled small business
• Compliance requires it (HIPAA, fintech, data residency)

Alternatives First

Before custom, try: Airtable (databases, workflows), Notion (docs + databases), Zapier/Make (integrations), Retool (internal tools). These can handle 80% of small business needs at 10% of the cost. Move to custom when you hit limits: complex logic, deep integrations, or scale.

Typical Budget for Small Business

At NanoStudio, most projects range $3K–$15K. Custom software from $2,500. Gets you a focused internal tool or simple MVP. Budget 15-20% annually for maintenance. If budget is tight, start with no-code. If you have the budget and the pain, custom pays off.
