What is a customer portal?
A customer portal is a secure website or app where customers see their orders, invoices, documents and tickets and complete tasks themselves. Stack18 builds portals connected to your ERP, CRM and helpdesk so customers get real-time answers and your team handles fewer routine calls.

Senior people lead every phase. Specialised AI agents on the Agentic SDLC handle the repetitive work, and nothing ships without your approval.
Discovery
We map today's process, systems and data for orders and invoices; payments; and support, talk to the people who run it and agree the baseline for status calls and invoice payment time so progress is measured from week one.
Design
We design the flows, roles, approvals and integrations for orders and invoices; and payments, and review a clickable prototype with the people who will use it before anything is built.
Build in weekly demos
We build in weekly demos, starting with orders and invoices, then payments and support. Each release is tested on your own data and passes a human approval gate before the next begins.
Launch and support
We migrate data, train your team and support go-live. After 30 days we review status calls, invoice payment time and ticket resolution time against the baseline and agree what to extend next.
Start small. Scale when it works.

Customer Portal Development questions.
Which systems can the portal connect to?
ERP, Tally, CRM and helpdesk tools with usable interfaces. We confirm yours in discovery. We confirm versions, plans and API limits during discovery, so there are no surprises on integration day.
Is it secure for sensitive documents?
We apply role-based access, encryption and audit trails and agree security requirements with you. Access is role-based, actions are logged and data handling terms are agreed in writing before work starts.
Can customers pay through it?
Yes. We integrate payment gateways and reconcile payments.
Can it be white-labelled?
Yes, with your branding and domain.
Web or mobile?
Both options are possible. We start with the channel your customers use most.
How much does Customer portal development cost?
Every engagement starts with a fixed-price Discovery Sprint that produces scope, a plan and a quote. Custom work is quoted at a fixed price once the scope is clear. Changes are agreed in writing before they are built, so the price you approve is the price you pay.
How do you measure success for Customer portal development?
In week one we agree a baseline for status calls, invoice payment time and ticket resolution time. We report them at every weekly demo and review them against the baseline 30 days after go-live, so results are measured rather than assumed.
What should we prepare before the first call?
Bring a short description of how Customer portal development works today, examples of the documents or screens your team uses, and the three numbers that matter most to you. A senior specialist will use them to outline a first step and a fixed price.
