Business Systems Development Osaka — Custom Builds for SMBs
We implement, through custom development (from scratch), the workflows that kintone and SaaS can't fully cover — or cover at too high a price. Inventory, ordering, customer management, attendance, reservations — we build business systems that fit your workflows 100%, within an SMB-friendly budget from ¥500,000.
Rather than the big-SI "millions of yen over 2–3 years" model, our hallmark is "agile custom development": we first deliver a working system in 8–12 weeks, then keep improving it as you operate. Embedding AI features is supported as standard.
Do any of these challenges sound familiar?
- ▸"Our operations run on Excel and manual work, but the errors and effort have hit their limit."
- ▸"We tried kintone, but the design falls apart once the workflow gets complex."
- ▸"We bought an off-the-shelf system, but it doesn't fit our operations and goes unused."
- ▸"Quotes for a cloud ERP come in at several million yen a year — overkill investment."
- ▸"We want a system that fits our operations 100%, built on a realistic budget."
Three reasons clients choose Sugureru
1. A working system delivered from ¥500,000 in 8–12 weeks
Custom development on the market typically starts at "1 year minimum, ¥5,000,000 and up." By leveraging AI-assisted coding, Sugureru delivers a Light custom build from 8 weeks and ¥500,000. It's a phased approach: first run your operations on a working system, then expand as needed.
2. Advice from the very "SaaS or custom build?" decision
We're not "an SI shop trying to sell you a custom build." If SaaS like kintone, Salesforce, freee, or MoneyForward will do the job, we'll tell you so honestly. We also support hybrid SaaS-and-custom architectures, and designs that fill only the gaps SaaS leaves with custom development.
3. "Next-generation" business systems with AI built in
Not just a business system: we embed ChatGPT / Claude as standard to provide "data-entry assistance," "past-case search," and "anomaly-detection alerts." Rather than a simple replacement of an old system, we build the business system of the AI era.
IT consulting & IT advisory
Talk to us even from the "I don't know where to start" stage. Instead of diving straight into development, we first map your current operations and IT environment, then work out the moves that truly matter together. As the external IT department for SMBs without in-house IT staff, we work alongside you from strategy through implementation and operation.
From ¥5,000/hour for spot consultations. Monthly advisory retainers are also available.
Problem mapping & operations audit
Through on-site interviews, we make your workflows and inefficiencies visible. We prioritize where automation or systemization will deliver the highest return on investment.
System selection & tool choice
From comparing SaaS, kintone, and custom development to judging whether AI adoption makes sense, we advise neutrally. We propose the best answer — including the option of "not building anything at all."
DX promotion & IT advisory
We don't stop at a one-off build — we keep working alongside you. We support IT investment decisions, vendor management, and building your internal structure, all from an external vantage point.
Examples of business systems we can build
Inventory management system
Centralize stock quantities, inbound/outbound history, optimal-stock alerts, and stocktake management. Barcode scanning, multi-warehouse support, and lot management are all supported.
Ordering / EC backend
Systemize the entire workflow — from order intake, quote and invoice issuance, and shipping instructions to payment management. Integration with EC marketplaces such as Shopify, Yahoo! Shopping, and Rakuten is also possible.
Customer management (CRM)
Customer information, deal history, project progress, and quote management, streamlined for SMBs. Ideal for companies for which Salesforce is overkill. Handovers between sales reps become smooth.
Reservation / shift / project management
Reservation intake, staff shifts, project progress, and deadline management, built to fit your industry. Centralized management linked with LINE Bots and web forms is possible.

How we work
-
01
Operations discovery & SaaS assessment
Where possible, we'll have you show us your current operations on site. We first judge whether kintone / SaaS will do or a custom build is needed. We only propose the parts where we judge "a custom build is genuinely necessary."
-
02
Requirements definition & quotation
We create screen mockups, data structures, and workflow diagrams. We also present which of Light / Medium / Custom is appropriate, along with a long-term cost outlook that includes phased expansion.
-
03
Agile development (two-week sprints)
Every two weeks we show you working screens and incorporate your feedback. This prevents the "we ended up with something different than expected" outcome and grows a system that truly fits your operations.
-
04
Production rollout & operation/maintenance
We handle production server setup, data migration, hands-on training for staff, and operating-manual creation. After release, we keep improving the system under a monthly maintenance plan.

Frequently asked questions
What's the difference from kintone or SaaS?
SaaS tools like kintone and Salesforce can be deployed quickly and cheaply for workflows that fit their standard features, but they hit limits with complex flows or unique processes. Custom development can fit your operations 100%, at the cost of higher upfront investment. At the discovery stage, Sugureru gives you a straight answer on whether SaaS is enough or a custom build is needed.
Can you migrate from Excel or Access?
Of course. We handle data migration and logic reproduction from existing Excel files, Access databases, and Google Sheets. Preparing (cleansing) the migration data is included in the initial build cost.
What support do you provide when the system goes down?
Under a monthly maintenance plan (¥50,000–200,000/month), we guarantee an initial response within 24 hours. For critical failures (operations come to a complete halt), we respond immediately. If you don't have a maintenance contract, we can still help on a per-request basis.
How much does maintenance cost?
The industry average is 15–25% of development cost per year, but Sugureru uses a fixed monthly rate of ¥50,000–200,000 (¥600,000–2,400,000/year). Cloud server fees (¥5,000–30,000/month) are billed separately at cost. The maintenance plan includes minor feature additions and improvements.
Can we hand the system over to an in-house team in the future?
Yes, we can design with handover in mind. We choose mainstream technologies that are easy to hire for, such as Next.js / Node.js / PostgreSQL. We deliver code, documentation, and operating procedures systematically, so the handover is smooth even when a successor engineer joins.
I'm worried about mid-project changes over a long development period.
We use an agile approach, showing you a working system every two weeks and incorporating your feedback. If a specification change comes up mid-project, we clarify its scope of impact and effort before deciding. This prevents the "we ended up with something different than expected" outcome.
Considering a business system? Start with a free consultation.
We welcome consultations even at the "is SaaS enough, or do we need a custom build?" decision stage. The first consultation and quote are free, and we usually get back to you within 24 hours.
