E-commerce solutions measured from the first click.
We build an online store around your brand and wire it to everything around it: an admin for day-to-day work, D Express delivery and tracking, fiscal receipts from our POS and measurement of the whole purchase, from the first visitor to a paid order.
What is connected
- Store, cart and orders built on Next.js
- D Express shipments, labels and tracking for the customer
- A fiscal receipt per order from our POS
- The GA4 e-commerce flow, SEO and tracking of the whole purchase
What the store looks like to a customer
Jig&Bau is a fishing tackle store we built, and it takes real orders. These are screenshots of the public site, exactly as customers see it. The design was made for Jig&Bau; your store gets its own.
A home page that says what you sell
The brand, the range and the way to buy are all on the first screen. On a phone the main button runs full width, right where the thumb is.
Categories that rank on Google
Every category is its own page with its own copy and products, built for what people actually type into search, such as “lures for pike”.
- Breadcrumb trail and internal links
- Its own search title and description
- Products pulled live from the catalogue
A product page that sells
Gallery, description, customer ratings and variant choice in one place. On a phone the price and the choose button sit in a bottom bar, so the cart is always within reach.
- Variants with their own stock levels
- Customer ratings and structured data for Google
- Cash on delivery or IPS QR payment
Guides and a blog that bring visits
Content that answers customers’ questions brings visits from search and leads them to products. Guides and blog posts are edited from the admin, with images per section.

Orders, delivery and fiscal receipts in one admin
Once an order arrives, every next step is in the same place: the D Express shipment, the label, tracking and the fiscal receipt from our POS. No retyping from one program into another.
The whole order on one screen
Status, customer, items, discount, shipping and total. One click from there creates the shipment or the fiscal receipt, and the customer gets an email whenever the status changes.
D Express shipments and labels
A shipment is created from the order or entered by hand. Labels print to D Express’s official specification, and the courier gets a list of parcels to collect.
- A guard against duplicate shipments for one order
- Several packages in one shipment
- Cash on delivery amount taken from the order
Tracking to the customer’s door
Statuses arrive from D Express automatically and show as a bar from Sent to Picked up, With the courier and Delivered, with a timeline of events. The customer sees the tracking number and parcel status in their account.
A fiscal receipt in one click
Clicking “Fiskalizuj” sends the order to Solve Kasa, our fiscal cash register in invoice.solve.rs. The receipt goes to the customer only when you decide. While Solve Kasa awaits approval from the Tax Administration, this step works in a demo environment only.
- Clicking twice returns the same receipt
- The register checks the order total
- Until approval you issue receipts in your own ESIR
Cash-on-delivery payouts matched in the bank
D Express pays out the collected cash in one lump sum. In invoice.solve.rs, Suggest group picks the oldest receipts up to the payout date that add up to exactly the inflow, so one click closes every order in that payout.
- An exact total, no guessing
- Other receipts wait for the next payout
- Per-parcel breakdown from the D Express portal
Admin and bank screenshots come from local copies with invented data and demo receipts. Solve Kasa is under review by the Tax Administration; until approval, “Fiskalizuj” runs in a demo environment and the receipt is not saved to the order.
When the catalogue gets more complex
Masterfish sells rods, reels, lures, line and tackle, so one category per product is not enough. The foundation is the same as Jig&Bau, while the catalogue and the brand were built from scratch. The store is in pre-launch.
Filters that cross-reference
Water, technique, rod class from UL to XH, target fish and lure type, combined in any order. Selected combinations are their own pages for Google, the rest are not indexed.
A lure for the fish you are after
The customer picks a fish and the store recommends lures and techniques that work for it, drawn from the catalogue itself.
Logo and brand from scratch
Mark, colours and typography in one design guide that both the store and the admin were built from.
Every step of the purchase is measured
A store that is not measured runs half blind: you do not know where customers come from, where they drop off and what brought them back. So we build measurement together with the store instead of adding it later. This is what runs today in the Jig&Bau and Masterfish stores.
The GA4 e-commerce flow
List view, product selection and view, add to cart, cart, begin checkout and purchase, with items, categories and revenue per product. Plus search, coupons and enquiries.
Purchases from the server too
Every order is also sent to GA4 from the server, independent of the browser and ad blockers, and tied to the customer’s session. Revenue does not vanish from reports when a customer runs a blocker.
Cookie consent
A banner and Consent Mode v2: analytics switches on only after consent, and the customer’s choice is remembered on the next visit.
Visits without cookies
Our own visit count, with no IP address and no identifiers, also records those who have not given consent. Visits by page, source and device are in the admin.
Campaigns and abandoned carts
UTM tags show which campaign brought a sale. An abandoned-cart reminder brings customers back, and the admin counts how many orders arrived after a reminder.
Search Console and structured data
We connect Search Console and GA4 before launch. Products carry price, availability, ratings, shipping and return terms in structured data for Google.
Ad pixels and conversions
If you advertise, we also connect the ad networks’ tools. They share the same cookie consent and the same e-commerce events, so a purchase is not measured in three different ways. This is not part of the Jig&Bau and Masterfish stores, so it is agreed per project.
Google Tag Manager
One place for tags and events, for when marketing changes measurement without a developer.
Meta Pixel and Conversions API
A purchase is sent to Meta ads from the browser and from the server, respecting the customer’s consent.
Google Ads conversions and remarketing
Purchases and add-to-cart as conversions, with audience lists to reach visitors again.
What goes into an e-commerce solution
A store is more than a catalogue and a cart. The real work starts when an order arrives, so we build that part together with the site.
A store built around your brand
Designed for your brand, not a stock template. Phone first, and fast even on a weak mobile connection. It is all Next.js, so the store can grow and be redesigned later without moving to another platform.
Catalogue, cart and payment
Categories, variants and stock that goes down with each order. A phone-friendly cart and checkout, cash on delivery or IPS QR payment, and confirmation emails for the customer.
An admin for daily work
Orders, customers, products and stock, coupons and discounts, reviews, guides, the blog and site content. You change it all yourself, no developer needed.
D Express delivery
Shipments from orders, labels, a courier pickup list and statuses that update by themselves. The customer sees the tracking number in their account.
Fiscal receipts and the books
A fiscal receipt per order from Solve Kasa (in a demo environment until the Tax Administration approves it). In invoice.solve.rs one D Express cash-on-delivery payout is matched to several fiscal receipts at once.
SEO and measurement from day one
Categories as landing pages, structured data for products with price, availability and ratings, a sitemap, guides and a blog. We connect the GA4 e-commerce flow and Search Console before launch.
How your store comes together
Call and scope
Range, delivery, payment methods and fiscal receipts: what the store must do on day one and what can wait.
Structure and design
We arrange categories around what customers search for on Google, then design around your brand.
Build and connect
Store, admin, the D Express and POS connections, measurement and customer emails, all checked before going live.
Launch and grow
Go live, connect Search Console and measurement, then add features as you need them: coupons, discounts or new guides.
Online store development FAQ
Can an online store issue fiscal receipts?
Yes, through Solve Kasa, our fiscal cash register in invoice.solve.rs: the admin clicks “Fiskalizuj” on an order and the receipt is created in the register. Solve Kasa is currently under review by the Tax Administration, so until approval this step works only in a demo environment and you issue receipts in the ESIR you already use.
Does the store have to use D Express?
The connection we have today is for D Express: shipments, labels, the courier list and statuses. For another courier we build the connection from its technical documentation, if it has any; we assess that on the first call.
How do customers pay?
At Jig&Bau customers pay cash on delivery or with an IPS QR code they scan in their banking app. Card payments need a contract with a bank or payment provider; once you have one, we can connect that too.
Which tracking tools do you connect?
In the stores we have built, GA4 runs with the full e-commerce flow alongside Search Console, and, where needed, server-side purchases, cookie consent (Consent Mode v2) and our own visit count. Meta Pixel and Conversions API, Google Ads conversions and Google Tag Manager are connected on request, with the same events and the same consent.
Does measurement respect cookie consent?
It can. On Masterfish analytics switches on only after consent (Consent Mode v2), and our own visit count uses no cookies, IP address or identifiers. You write the cookie and privacy policy text with your own lawyer.
Can I edit products and content myself?
Yes. Products, prices, stock, coupons, reviews, guides, the blog and home page content are all edited from the admin, no developer needed.
Can my store look different from Jig&Bau?
Of course. Jig&Bau is an example, not a template: we design around your brand. It is all Next.js, so the store can be changed, extended and redesigned later without moving to another platform.
Do you also design the logo and brand for the store?
Yes. For Masterfish we designed the logo, colours and typography before the store and wrote them into a design guide, so the store and the admin look like one brand. If you already have a brand, we build the store around it.
Do you also work with WooCommerce?
Yes. We built the Azzuro.rs store on WordPress and WooCommerce. We choose a custom Next.js store when speed, SEO and the delivery and POS connections come first.
How much does an online store cost and how long does it take?
It depends on the range, the design and the connections you need: delivery, fiscal receipts, payments. After a short call you get a proposal with scope, timeline and price. For reference: we built the first version of the Jig&Bau store in 24 hours and added delivery and fiscal receipts later.
