One person you can actually call.

I’m Isaac Riehm, and DevPlus is my company. I fix and build websites. I also build the software a business runs on: scheduling, quotes, invoicing, billing, and the paperwork in between.

Every job starts the same way: a phone call and a free look. Website fixes have flat prices. Software gets a fixed price in writing, and you see progress every week. At the end, you own the work, the data, and the accounts.

When a job needs a specialist, I bring in someone I trust and tell you who. I use modern tools that let one person build what used to take a team. You deal with the person who built it, before and after it launches.

Call or text anytime. If I don’t pick up, I’ll call you back the same day.

For accountants and bookkeepers

If a client bills from a spreadsheet or types the same numbers twice, send them my way.

  • You stay their accountant. I don’t do books or taxes.
  • Before anything touches QuickBooks, I check what it allows and tell you both.
  • Accounts are set up in your client’s name, and my access is limited to what the job needs.
  • Call or text me with their name, or have them call. The first call and a look are free.

Questions owners ask

Is it really just you?
Yes. The person you call is the person who plans it, builds it, and answers the phone afterward. When a job needs a specialist, I bring in someone I trust and tell you who.
Where are you?
Scottsdale. I work across the Phoenix area and will come to your office. Much of the work also runs fine over the phone and a shared screen.
What does it cost?
Website fixes have flat prices: $150 for a small fix, $450 to repair or upgrade a site, and $900 for a rebuild or new site. Software is quoted after a free first look, as a fixed price in writing. You know the number before any work starts. What each website price covers
What happens if something happens to you?
You own everything: the program, your data, the accounts, and a written guide to how it works. It is built with common tools any good developer can pick up. You never depend on me alone.
Will you sign a Business Associate Agreement?
Yes. We sign one before any patient information is involved.
