Custom software vs off-the-shelf: a 10-minute decision guide

Buy software when a known product does 90% of the job and your process is standard. Build when the workflow is the business, when the off-the-shelf tool forces your team to work its way, or when your data must connect to something no vendor supports. Start with one workflow, one team, one month.

Three questions

  1. Does a product you can name do 90% of this today? If yes, buy it and spend the difference on adoption.
  2. Is the workflow your competitive advantage, or just your habit? Habits should bend to good software. Advantages should not.
  3. Does the data need to connect to something the vendor does not support? Integrations are where off-the-shelf tools quietly fail.

Where custom wins

  • Quoting and estimating that depend on your price book and your history.
  • Intake that has to route to the right person with the right information the first time.
  • Portals where customers see exactly their status and nothing else.
  • Anything that currently lives in three spreadsheets and a group text.

Where custom loses

  • Accounting, payroll, email marketing, and calendars. Buy them.
  • A CRM for a team under ten people that uses it the standard way.
  • Anything you would be the only customer of and would not maintain.

What a small first build looks like

One workflow, one team, one month. An internal portal or dashboard runs $15,000–$25,000 and takes 4–6 weeks. A quoting tool with a customer link and e-signature runs $18,000–$35,000 over 6–8 weeks. The scope is fixed, the price is fixed, and you own the result.

On a discovery call we will tell you which of the three you are looking at, including when the answer is to buy something.
