Custom software & SaaS

AI SaaS and custom software development in Guangzhou.

Build the product around the work users need to finish. Yander connects product design, frontend and backend engineering for AI tools, SaaS platforms and business systems, with English or Chinese collaboration from Guangzhou.

KIMEO connects generation with editing and export; Unico connects storefront building with orders and merchant operations. For your project, we define one complete first-release workflow, its acceptance criteria, and the accounts and documentation needed to operate it.

Best fit

  • A founder validating one workflow before expanding an AI SaaS MVP
  • An AI product that needs editable output, saved work, review and export around model generation
  • A SaaS platform connecting a customer-facing builder or storefront to orders, payments and admin work
  • A business replacing spreadsheets or disconnected tools with a shared operational system

What we deliver

01

First-release scope and acceptance criteria

Map the target users, core task, roles, data, integrations and failure states. Agree what must work in the first release and what belongs in later phases before estimating the build.

02

Product design and editable workflows

Design the complete path through input, processing, review, editing, saved work and output where needed. Prototype the decisions that carry the most uncertainty before committing to a wider interface.

03

Application and business-system integration

Build the agreed UI, APIs and database behavior, with authentication, permissions, AI providers, payments, storage or notifications according to scope. Plan timeouts, retries and account states alongside successful flows.

04

QA, deployment and operating handoff

Verify acceptance criteria and critical permission and integration paths. Agree deployment access, source-code handover, operating notes and post-launch responsibilities. Ongoing operations and third-party costs are scoped separately.

How we approach it

  1. 01Walk through a real task and sample inputs; identify who approves the output and where it goes next.
  2. 02Prove uncertain model behavior or integrations with a focused prototype and reviewable test cases.
  3. 03Build the first complete workflow, including permissions, error states and the admin actions needed to support it.
  4. 04Review against agreed acceptance criteria, prepare the client-controlled production accounts and handover, then plan the next phase from usage.

Typical capabilities

  • Next.js, React, and TypeScript web applications
  • API, database, authentication, and role-based access
  • Payments, subscriptions, marketplace payouts, and credits
  • AI, storage, email, and third-party integrations
  • Admin operations, testing, deployment, and monitoring readiness

Guangzhou · English / Chinese · Worldwide

Scope your AI SaaS around one complete user task.

Connect the user experience with the systems needed to run it. Discuss generation, editing, saved work, payments and admin operations with the same Guangzhou product and engineering team, in English or Chinese.

Start with your project brief
Share one user workflow, anonymized input and expected output examples, required edits or exports, roles, integrations, budget range and first-release timing. Identify who will review the result before we prepare an estimate.
Direct bilingual collaboration
Discuss requirements and decisions directly in English or Chinese, with remote collaboration for overseas teams.
Agree on the handoff before development
Confirm source-code ownership, repository and deployment access, documentation, and ongoing support in the project scope.

Service FAQ

Can Yander start with an existing specification or codebase?

Yes. We review the product model, code quality, deployment and constraints, then agree what to preserve, repair or rebuild. Data migration and continuity requirements are planned before changing a live system.

Do you build both the customer product and admin tools?

Yes when both are required. We scope customer journeys alongside permissions, support, moderation, reporting and other operational workflows needed to run the product.

Can payments, subscriptions or marketplace payouts be included?

Yes. We assess the provider and flow against your business model, target countries, refunds, taxes and compliance requirements. Payment accounts and ownership of funds are clarified before integration.

How long does custom software take?

The schedule follows the first-release workflow, integrations, data readiness and approval process. An AI prototype, editable canvas and a payment-backed SaaS release have different dependencies. After reviewing the brief, we agree milestones and acceptance criteria; an estimate becomes a commitment only in the project agreement.

Who owns the code, data and deployment accounts?

The agreement defines custom code ownership, data access and third-party licences. We deliver the agreed repository and documentation; cloud, database and service accounts should be controlled by your team, with access for development and handover.

Can we collaborate in English across time zones?

Yes. Requirements, project discussions and handover documents can be provided in English. We agree meeting times, written updates and decision owners. Guangzhou meetings can be arranged by appointment, subject to availability.

How do pricing and post-launch support work?

We quote by agreed phases and deliverables. Cloud services, third-party fees, maintenance and new features are separated where applicable. Bug support, monitoring, backups, updates and response times are specified in the support scope.

How do we define an MVP, acceptance criteria and later changes?

Start with one user, one valuable task and the minimum operational flow that supports it. For AI features, agree representative inputs, acceptable output, human review and failure handling as well as screens. Acceptance criteria define what is delivered; new requirements are assessed for scope, schedule and cost before being added.

Can you migrate existing data and help with the production handover?

Migration can be included after reviewing the source data, access and any downtime constraints. The plan can cover field mapping, test imports, reconciliation, backups and a rollback approach suited to the system. Before launch, we agree the production accounts, operating instructions, handover items and who can approve the cutover.

What testing and security work is included, and who operates the system?

Testing is scoped to the product's workflows and risks, including permissions, integrations, failure states and security checks where relevant. We agree who handles hosting, monitoring, backups, dependency updates and incidents after launch. Third-party security testing or ongoing operations require an agreed scope and are not automatically included.

What should we prepare for an AI SaaS estimate?

Share the target user, one real task, anonymized sample inputs and expected outputs, existing product or prototype, required integrations, target markets, budget range and timing. Identify a decision owner and any data, deployment or licence restrictions. Arrange sensitive data and account access after boundaries have been agreed.

What drives the cost of an AI SaaS MVP?

Cost depends on the workflow, editable output requirements, roles, integrations, payments, admin tools and production reliability needed. Model usage, storage, hosting and other provider fees recur separately. We can scope a validation phase before a larger build; model training, data preparation and ongoing operations are included only when explicitly agreed.
