Yarify is a custom software development company. We build internal tools, client and partner portals, integrations between CRM, ERP, accounting and e-commerce systems, and workflow automation, including AI steps where they save real time. A senior engineer scopes the work with you, then you get a fixed written quote; if our estimate was wrong, the extra hours are our cost. It runs on your cloud, and you own the code.

Custom software vs off-the-shelf SaaS
| Factor | Off-the-shelf SaaS | Custom software |
|---|---|---|
| Fit to your process | You adapt to the tool | The tool follows your process |
| Upfront cost | Low | Higher, fixed quote |
| Ongoing cost | Per-seat fees that grow with you | Hosting and maintenance, no seat fees |
| Integrations | What the vendor supports | Anything with an API, a file or a database |
| Ownership | Vendor owns the product | You own the code and the data |
What custom software costs
A single integration or focused internal tool sits at the low end. A multi-role portal with several integrations costs considerably more. Messy source data is the usual surprise, so we check it during scoping.

Questions buyers ask us
What is custom software development?
Building software for your business process instead of adapting your process to a generic product. Usually that means internal tools, client portals, integrations between existing systems and workflow automation, not replacing everything with one big system.
How much does custom software cost?
From a small project for one integration or internal tool to a larger investment for a multi-role portal. You get a fixed written quote after a free scoping call, and our estimation overruns are our cost.
Can you integrate our CRM, ERP and accounting software?
Usually, yes. If a system has an API, webhooks, a readable database or scheduled exports, we can connect it. Integrations get retries, logging and alerts, so failures are visible instead of silently losing data.
Should we build custom software or buy a SaaS tool?
If a standard tool covers your process well, buy it. Build when the process is your edge, when integration gaps cost hours every week, or when seat fees grow faster than the business. Often the answer is a small custom layer between tools you already pay for.
Do we own the software you build?
Yes, 100% of the code and IP. It runs on your own cloud account with no per-seat fees to us. You get documentation so another team, or your own IT, can maintain it.
Who maintains the software after launch?
Your choice: ongoing support or a dedicated team with two weeks’ notice, or a documented handover to your IT. Well-built automation needs little upkeep: one content automation platform we built needs about an hour a month.
