Custom software development services from senior engineering teams

Ryz Labs builds custom software for processes that off-the-shelf tools do not fit: the spreadsheet that runs a department, the aging internal app nobody wants to touch, the manual copy-paste between your CRM and ERP. A senior Ryz team, drawn from the top 1% of the engineers we interview, maps the real workflow, builds the system in your cloud and works with your team on US business hours until people actually use it.

What we build

Custom software development is different from general product work. The users are usually your own staff or partners, the requirements live in people's heads, and the system has to fit around tools you already pay for.

• Spreadsheet replacements: a web app with a real database, validation, permissions and history for the pricing model, capacity plan or tracker that currently lives in a shared Excel file.
• Workflow and approval systems: multi-step approvals, routing rules, SLAs and notifications, with every state change recorded so you can answer "who approved this and when".
• Internal operations portals: one place for support, operations or finance teams to see customer, order and account data that is spread across five systems today.
• System integrations: syncing Salesforce, NetSuite, SAP, Microsoft Dynamics, HubSpot or your own databases, with retries, idempotency and reconciliation reports.
• Partner and client portals: secure external access for customers, brokers, suppliers or field staff, with SSO, document exchange and role-based views.
• Legacy tool replacements: rebuilding an Access database, a VB6 or classic ASP app, or an unsupported vendor tool on a modern stack, migrating the data with it.
• Reporting back ends: the data model and pipelines behind the operational reports people currently assemble by hand every Monday.

How an engagement works

1. Talk. We start with the process, not the screens: who touches it, what breaks, which systems hold the data, and what "working" means for the people who will use it.
2. Match. We propose a team scoped to the build, typically full-stack engineers plus an integration specialist, with names and a monthly price.
3. Join. The team works in your repos and cloud, joins your standups, sits in on the current workflow (often over screen share with the people who run it) and demos working software every week.
4. Grow. After launch, keep a smaller team for enhancements, extend the system to the next department, or hand it over to your engineers with documentation and runbooks.

Week 1 is discovery: shadowing users, collecting the spreadsheets, macros and email threads that define the process, and listing every system the software has to talk to. Month 1 typically produces a working slice for a few real users, with one real integration connected. By month 3, the core workflow is in daily use, data has migrated from the old tool, and the team is working through the edge cases that only show up in production. The pace depends on scope and how quickly access to source systems is granted.

The stack our teams work in

How we make custom software stick

The usual failure is not a crash. It is a system that launches and then gets quietly abandoned while the old spreadsheet comes back. These are the causes we design against.

• Requirements that miss the real process. The documented process and the one people follow differ. We watch the work, collect the macros and exception lists, and turn the hidden rules into explicit, tested business logic.
• Bad data migration. Spreadsheets carry duplicates, merged cells and free-text dates. We profile the data early, write repeatable migration scripts, run them against copies and reconcile row counts and totals before cutover.
• Fragile integrations. ERP and CRM APIs throttle, time out and change. Our engineers build integrations with idempotent writes, retry queues, dead-letter handling and a daily reconciliation report, so a failed sync is visible and fixable.
• Permissions as an afterthought. Internal tools often hold salary, pricing or client data. Role-based access, change history and least-privilege service accounts are in the first release, not the fifth.
• Slower than the spreadsheet. If entering a record takes longer than typing in a cell, people go back. We test with real users, add bulk edit, import and keyboard shortcuts, and keep pages fast.
• Nobody can maintain it later. We use the frameworks your team knows, write tests around business rules, and leave architecture notes and runbooks so the next engineer is not reverse-engineering logic.

Team shapes and cost

Typical Ryz cost is $7,000–$15,000 per engineer per month, mostly mid-level to senior: mid-level (comparable to Amazon L5) at $7,000–$10,000, senior (comparable to Amazon L6) at $10,000–$15,000, and leads at $15,000+, quoted per team.

• Single-workflow build: 2 senior full-stack engineers. 2 × $10,000–$15,000 = $20,000–$30,000 per month. Fits one spreadsheet replacement or one integration.
• Internal platform team: a tech lead, 3 full-stack engineers and 1 integration engineer. 4 × $7,000–$15,000 = $28,000–$60,000, plus the lead at $15,000+, so about $43,000–$75,000+ per month.
• Modernization team: a tech lead, 4 senior engineers and a QA engineer for replacing a large legacy tool. 5 × $10,000–$15,000 = $50,000–$75,000, plus the lead, so $65,000+ per month.

Total project cost is team size × duration × monthly rate: a 2-engineer senior team for 4 months is 2 × 4 × $10,000–$15,000 = $80,000–$120,000. You get a scoped plan, a price and the names of the people before you start.

Dedicated team or staff augmentation?

A dedicated development team fits when nobody on your side has time to own the build: the team runs discovery, design, development, migration and launch, and reports to your sponsor. That is the usual model for a new custom system.

Staff augmentation fits when you have an internal tools or IT engineering group with a backlog. Senior full-stack developers work on your team, under your tech lead, in your process. If the system has a large legacy component, see legacy application modernization.

When Ryz isn't the right fit

If a configurable SaaS tool covers 90% of the process, buy it and spend engineering on integration instead. If you want a self-serve freelance marketplace for a small hourly fix, or engineers on European or Asian hours, other providers fit better. And if you need a management-consulting engagement to redesign the business process itself, start with a consultancy.

FAQ

When does custom software make more sense than buying a SaaS tool?

When the process is a real differentiator, when you would need heavy customization of a vendor tool anyway, or when the main job is connecting systems you already own. If an off-the-shelf product fits most of the workflow, buying is usually cheaper.

How much do custom software development services cost with Ryz?

Typical cost is $7,000–$15,000 per engineer per month, mostly mid-level to senior, with leads at $15,000+ quoted per team. A project's cost is team size × duration × monthly rate, so we scope the team and timeline first and give you a plan, a price and names.

How fast can work start?

After the scoping call we propose a team with named engineers. Most of the timeline depends on scope and your onboarding, especially access to the source systems and the people who run the current process.

Who owns the code and the data?

You do. The team works in your repositories and your cloud accounts, and the data never leaves your environment.

Can you integrate with our ERP or CRM?

Yes. Our engineers work with Salesforce, NetSuite, SAP, Dynamics 365 and HubSpot APIs, including the batch and file-based interfaces older systems rely on.
