At a glance

The project started from scratch. The client had no old website and no existing online sales process to migrate. The goal was to launch a virtual-office service so that a new sole proprietor or LLC, as well as an established business, could choose a suitable package and complete the order online.

What the finished site looks like

The site virtualnesidlo-trnava.sk walks a visitor from an explanation of the service to an order. The main menu has the sections Virtuálne sídlo, Cenník, Ako začať, and Legislatíva (virtual office, pricing, how to start, legislation); the pricing page places the packages for sole proprietors and LLCs next to the one-off services. The Objednať sídlo (order an office) button opens a three-step order: contact, correspondence, payment.

About the solution

With a virtual office, the purchase does not end when the order is paid.

A subscription renews, the payment method can change, and a bank transfer can arrive later.

01 / 04 Ordering

Subscriptions and one-off services in one ordering flow

A customer can order both the recurring virtual-office service and one-off services. At checkout, they choose between card and invoice; for a bank transfer, the solution also supports Pay by Square.

The subscription then continues in the client account. There the customer can work with the subscription status, change payment details, and receive documents for the following periods. Once a subscription has been canceled, the customer cannot reactivate it on their own with one click; it continues through a new order or an administrator's action.

One-off purchases follow a simpler flow. The order and payment go through the same application, the administrator sees them in the system, and the customer receives an email confirmation together with the payment documents. These one-off purchases do not appear in the client account.

Business outcome

The customer picks a package or a one-off service and completes the order online.

Detail

One-off services are ordered in the same application as subscriptions.

At payment, the customer chooses card or bank transfer with Pay by Square.

02 / 04 Payments

The hardest part starts after payment

The most technically demanding part of the project was synchronizing payment states between Stripe and the web application. Handling a successful card payment was not enough. The solution also has to react to a switch from card to invoice and back, recurring payments, Stripe invoicing, and events arriving through webhooks.

Edge cases mattered too: an invoice payment can arrive late, the customer may cancel the service in the meantime, or the next recurring payment may fail. So the application does not just record whether a payment succeeded once; it keeps the order and subscription status current through changes that happen later.

Business outcome

The order and subscription status stays current through late payments, cancellations, and failed renewals.

  1. Payment Card · invoice · Pay by Square
  2. Events Stripe webhooks · recurring payments
  3. Edge cases Late payment · cancellation · failed renewal
  4. Output Current order and subscription status

Client account: the subscription, the next payment, and retrying a failed payment.

Administration: payment history, including voided and uncollectible invoices.

03 / 04 Operations

Automation where it makes sense

The virtual-office service itself is currently delivered manually. After the first successful order and payment, the administrator contacts the customer and handles the next steps personally.

The web application does not replace this operational work. Instead, it sends the administrator the information they need to act on, for example when a customer cancels a subscription or the next recurring payment fails.

The admin area follows the same principle. It is deliberately narrow: orders, payment history, and actions to cancel or resume a subscription. It is not a general back-office system with features this business does not need.

Business outcome

The administrator is notified when action is needed and delivers the service personally.

Administration: an orders overview with counts, a filter by status and service, and the orders table.Order detail: customer, order, address, subscription, and subscription actions.

Administration: the orders overview with a filter by status and service.

Order detail: customer data, the subscription, and actions such as checking the payment or canceling the subscription.

04 / 04 Content

All content and offerings, managed in Sanity

The public site content, including products and subscriptions, is managed in Sanity. That lets the client change their offerings and content without products or copy being hard-coded in the application.

The technical solution is built on Next.js, React, TypeScript, and Tailwind CSS. Stripe handles the payment layer, Sanity the content, and the application is deployed on Vercel.

Business outcome

The client changes offerings and content without touching the application code.

Sanity Studio: the SRO Komfort package as a document the client edits on their own.
Detail: the content structure in Sanity Studio, Balíky virtuálneho sídla (virtual-office packages), Jednorazové služby (one-off services), Doplnkové služby (add-on services), and the package list with SRO KomfortDetail: the document fields Názov balíka (package name) SRO Komfort, Podtitul (subtitle), and Cena / mesiac (price per month)
Detail

Packages, one-off services, and add-on services are separate documents in Sanity.

The client edits the package name directly in the document field.

Result

What the client got

  1. In 14 business days, we delivered a complete solution for a new business: a public website, online ordering, subscriptions and one-off purchases, several payment methods, a client account, administration, and a CMS.

  2. The most important result of the delivery is not the number of screens but the fact that the order does not end at checkout. The system keeps working with the payment and subscription status and gives the administrator the information needed to deliver the service manually.

“Proposal, cooperation, delivery on time — 10/10. Very good, helpful approach and great collaboration 🙏✅”
