In short
Byteinfy builds Shopify stores on Online Store 2.0 from $2,000: editable custom sections, checkout extensions and headless storefronts when the case is real, with a fixed quote after a scoping call and 30 days of post-launch support.
Last updated 5 September 2026 · Written by the Byteinfy team, which builds and operates SwipeReel and myBillPlease.
Who it is for
- Brands launching on Shopify for the first time
- Stores that outgrew a purchased theme
- Teams that need custom sections without a developer on call
- D2C brands in India selling with COD, UPI and partial payment
What you get
- Theme architecture on Online Store 2.0 with JSON templates and editable sections
- Custom sections and blocks, built in Liquid with zero-JS defaults
- Checkout UI extensions and Shopify Functions where the flow needs them
- Product, collection and landing page templates tuned for conversion
- Core Web Vitals budget agreed up front and measured before launch
- Analytics, pixels and consent wired correctly from day one
How it works
- 1
Scope
A 45-minute call, then a written scope with a fixed quote and a timeline. No surprises later.
- 2
Design
Section-level design in Figma, reviewed on the real theme editor so what you approve is what ships.
- 3
Build
Weekly demos on a password-protected preview store. You test on your own phone, not on our slides.
- 4
Launch
DNS, redirects, payments and speed checks handled. We stay on for 30 days after launch.
Pricing
From $2,000
A launch-ready store on Online Store 2.0 usually lands between $2,000 and $8,000 depending on catalogue size, integrations and custom sections.
Questions we get asked
- Do you build on a purchased theme or from scratch?
- Both. If a premium theme covers 80% of what you need, we customise it. If not, we build a custom theme on Online Store 2.0 so every section is editable by your team.
- Can you handle Indian payments and COD?
- Yes. Razorpay, PayU, Cashfree, UPI and Cash on Delivery with OTP verification and partial prepaid, using our own COD app where it fits.
- How long does a store take?
- A themed store ships in two to three weeks. A custom build with integrations is usually five to eight weeks.
- Is headless worth it for us?
- Usually not below a few crore in annual revenue. We say so on the scoping call, and we build headless with Hydrogen when the case is real.
