Admin Panels and Back-Office Software
We build the internal tools your operations, support and finance teams use every day: fast, secure admin panels that replace database scripts, spreadsheets and risky manual fixes.
Internal Tools Deserve Product-Grade Engineering
Every digital product needs a back office. Operations teams approve merchants, support agents refund orders, finance reconciles payouts and content teams moderate listings. Too often these jobs run through direct database access, one-off scripts or an admin screen built in a hurry during launch. That works until volume grows, a mistaken update corrupts data or an auditor asks who changed a customer’s record and why.
Hanoi Technology builds admin panels and back-office systems with the same care as customer-facing products. We design role-based access, safe bulk operations, approval workflows, audit logs and fast search over large datasets. Depending on the need, we build fully custom applications, use frameworks such as React Admin or Refine to move faster, or configure internal tool platforms where they fit.
The Challenge
Back-Office Problems We Fix
Weak internal tools quietly slow down the whole business.
Direct Database Access
Engineers run SQL in production to fix orders or accounts because no tool exists. Mistakes are hard to trace, and developers become a bottleneck for routine operations.
Admin Screens That Do Not Scale
Pages that loaded quickly with a thousand records time out with millions. Filters are missing and staff export to spreadsheets just to find what they need.
No Audit Trail
When records change, nobody can see who did it, when or why. Fraud investigations, customer disputes and compliance audits become guesswork.
Everyone Is an Admin
A single admin role gives every staff member full access. Sensitive data is overexposed and a single compromised account can cause serious damage.
Business Value
What a Well-Built Back Office Delivers
Self-Sufficient Operations Teams
Staff handle refunds, approvals, corrections and configuration themselves. Engineers return to product work.
Least-Privilege Access
Roles and permissions match job functions, down to individual fields and actions. Sensitive operations can require a second approver.
Full Traceability
Every change records the user, time, previous value and reason. Investigations and audits are answered from the log.
Speed on Large Datasets
Indexed search, server-side filtering and pagination keep screens responsive at scale. Staff find any record in seconds.
Safe Bulk Operations
Imports, mass updates and batch actions include previews, validation and undo where possible. Large changes stop being risky events.
Operational Visibility
Dashboards show queues, backlogs, exceptions and key metrics. Team leads see where work is piling up.
Your Back Office Is Part of Your Product
Customers never see the admin panel, but they feel its quality in how fast refunds arrive, how accurately orders are fixed and how quickly fraud is stopped. Investing in internal tools improves customer experience and reduces operational risk at the same time.

Our Approach
How We Build Back-Office Systems
We start from the riskiest and most time-consuming manual work.
- 01
Shadow the Operations Team
We watch how staff handle real cases, document workarounds and collect every script engineers run on their behalf.
Deliverables: Task inventory · Pain point summary
- 02
Design Permissions and Screens
We define roles, approval rules and audit requirements, and prototype the most used screens with the people who will use them.
Deliverables: Role and permission matrix · Screen prototypes
- 03
Build the Foundation
Authentication, permissions, audit logging and the API layer are built first, so every later feature inherits them.
Deliverables: Security foundation · Back-office API
- 04
Deliver Workflows in Priority Order
Features are delivered in sprints, starting with those that remove database access or the most manual effort. Teams test each release.
Deliverables: Released workflows · Sprint demos
- 05
Measure and Evolve
We track usage, time saved and error rates, then continue adding tools through a dedicated team or managed service.
Deliverables: Usage analytics · Improvement backlog
Use Cases
Back-Office Solutions We Build
Examples of internal tools that change how operations teams work.
Marketplace Operations Console
Operations staff onboard sellers, verify documents, approve listings and handle disputes. Every decision is logged with the reviewer and reason.
Fintech Back Office
Compliance and finance teams review KYC cases, approve payouts with maker-checker controls and reconcile transactions. Sensitive data is masked by role.
Delivery Dispatch Control Panel
Dispatchers monitor live orders, reassign drivers and handle exceptions from one screen. Supervisors see delays and capacity in real time.
Content Moderation Workspace
Moderators review flagged posts, images and profiles in a queue with keyboard shortcuts and decision templates. Escalations go to senior reviewers.
Subscription and Billing Admin
Support agents adjust plans, issue credits and pause subscriptions within limits set by role. Larger adjustments require finance approval.
Configuration and Pricing Management
Product managers update prices, promotions and feature flags with scheduled changes and previews. Mistakes can be rolled back quickly.

Admin Panel FAQ
Should we use Retool or build a custom admin panel?
Internal tool platforms are excellent for quick, low-risk tools used by small teams. Custom development is better when the back office is large, used all day by many staff, needs complex permissions or approvals, must handle very large datasets, or when per-user platform pricing becomes significant. We often combine both: a custom core for critical workflows and a platform for occasional utilities.
How do you secure an admin panel?
We place it behind single sign-on with multi-factor authentication, restrict network access where possible and apply least-privilege roles down to fields and actions. Sensitive operations require approvals, every change is logged and the API layer enforces permissions server-side rather than relying on the interface. Regular security testing is part of our delivery process.
Can the admin panel work with our existing database and services?
Yes. We usually build a dedicated back-office API that talks to your existing databases and services, so business rules are enforced consistently and direct database writes are avoided. Where your product already exposes internal APIs, we reuse them. This approach lets us add a modern admin interface without rewriting the underlying system.
How long does it take to build a back-office system?
A focused admin panel covering core entities, search, editing, roles and audit logging can typically be delivered in a few months or less, depending on data complexity. Larger back offices with many workflows are delivered incrementally, starting with the highest-value tasks. Teams usually start using the first features within the first few sprints.
How do you handle large datasets in admin screens?
We use server-side pagination, filtering and sorting, add database indexes for common queries and introduce a search engine such as Elasticsearch where full-text or faceted search is needed. Exports and bulk operations run as background jobs with progress tracking, so the interface stays responsive even when operations involve millions of records.
Can you modernize our old admin system?
Yes. We review the existing system, document what it does, including undocumented behavior, and plan a migration that keeps operations running. Often we build the new panel alongside the old one and move workflows over gradually, retiring the legacy system once every function has a tested replacement and staff are trained.
