Software shaped around your workflow
Off-the-shelf tools make you change how you work to fit them. Custom software fits the way the work is actually done, and removes the copying, chasing and re-typing in between.
PreOp Screen is a good example. An anesthesia practice phoned patients one by one before surgery. We built a three-minute form on the patient's phone, automatic checks against the doctor's own rules, a worklist with the riskiest patients at the top, and a report the doctor signs in one click. Signed reports are locked, so the surgeon always sees exactly what was signed.
- Web applications. Portals, dashboards and tools for customers or staff.
- Enterprise systems. Roles, permissions, audit trails and approvals.
- APIs and integrations. Connecting the systems you already pay for.
- Cloud platforms. Built to grow, deployed where your data needs to live.
Fixed scope, fixed price
After one discovery call you get a fixed, line-item quote, so you know what each part costs before work starts. The scope is written down, which protects both sides: you know what you are getting, and we know what we have promised.
When the project includes AI, those parts are priced on our published packages: Launch at $4,900 in 2 to 3 weeks, Product at $12,000 in 4 to 6 weeks, and Custom from $25,000.
Legacy modernisation
Modernising a legacy system usually means refactoring what works rather than rewriting everything. We keep the parts that are sound, replace the parts that hold you back, and move in steps so the business keeps running throughout.
Esperwise shows the other side of custom software: around an AI assistant sits everything a clinic runs on, from patients and appointments to scanned documents and transcripts, with each role seeing only what it should. The AI is one part. The software around it is what makes it usable every day.
An AI product your customers or team use every day.
Step 2 · Add partsPrices from our published list. We confirm the final, fixed price on one call. Running costs such as AI models, hosting and phone minutes are paid to those providers directly.
