Selling a brake caliper online means fitment logic a stock Shopify theme cannot do

A custom theme and store setup runs $20,000 to $35,000, a fitment or B2B pricing build runs $35,000 to $60,000, and a full custom store with ERP sync runs $60,000 to $90,000. Fitment logic and B2B rules drive most of the cost, not the number of products.

Yes. We build a fitment engine backed by a maintained parts database so a shopper sees only parts that fit their vehicle. That cuts wrong-fit returns, which is the expensive problem a stock theme quietly creates.

Yes. We add real B2B pricing tiers, quantity breaks, account-specific terms, and bulk reordering, so your distributor and shop customers get pricing the standard cart cannot express. Retail and wholesale can run on the same store.

Yes. We sync inventory two-way with your ERP or inventory management software, so the store reflects real availability and you stop overselling stale counts. This is the integration app bundles rarely do reliably.

Yes. Custom development sits on top of Shopify, so you keep its reliable checkout, hosting, and payment handling while owning the fitment, pricing, and sync logic. You get the platform's strengths without its catalog limits.

Apps are convenient until you stack eight to fake fitment and B2B pricing, at which point the store slows and breaks on updates. Custom logic replaces that stack with owned code that performs and does not surprise you when an app changes.

Fitment data needs sourcing and periodic updates, which is real ongoing work. We set up the database and a process to keep it current, and this upkeep is worth budgeting for, since wrong fitment data causes returns.

Yes. Orders and tax details flow to your accounting system so the roughly 9.75 percent Rutherford County sales tax and your records stay clean. We integrate rather than duplicate your bookkeeping.

A custom theme launches in 6 to 10 weeks, while a fitment or B2B build runs 10 to 14 weeks and a full store with ERP sync 14 to 20 weeks. We can launch core commerce first and add advanced logic in phases.

Ask four things: to see the Git repository of a past build, whether they work in Online Store 2.0 sections, how they ship changes without editing core theme files, and for a reference from a store at your revenue level. Then require a written specification listing every template, app, and integration before they price the work. A developer who quotes off a homepage screenshot has already told you how the project will go.

Budget 15-20% of the original build cost per year, which on a $100,000 system means $15,000 to $20,000 for security patches, dependency updates, bug fixes, and small improvements as real usage reveals what the spec missed. Cloud hosting for a typical business application adds $50 to $300 a month on top. Skipping maintenance does not save the money; in Digital Heroes rescue work, unmaintained systems typically need a far more expensive rebuild within about three years.

Because the low quote prices a theme install and the high quote prices software. A $3,000 bid typically covers configuring a purchased theme, while a $50,000 bid covers custom Liquid sections, wholesale or subscription logic, ERP sync, and load testing before launch. Ask each bidder which templates they are building from scratch and which integrations they own end to end, and the gap usually explains itself.

Yes, and for many stores that is the smartest first move. Dawn is Shopify's free reference theme, built on Online Store 2.0 with fast performance out of the box, and a developer can extend it with custom sections instead of starting from zero. Most custom builds we deliver under $10,000 start from Dawn rather than a blank theme because it cuts both cost and risk.

Two to four for most projects: a Shopify developer, a designer, and a project lead who also runs QA, with a second developer added for integration-heavy builds. Plus and headless projects justify four to six. Be suspicious of both extremes; a solo generalist on a complex build is a single point of failure, and a ten-person team on a theme build means you are paying for meetings.

Do the subscription math. An app at $50 a month is $3,000 over five years and ships tomorrow, so apps win for standard problems like reviews, email, and loyalty; custom wins when you would need three apps fighting over the same cart or the feature is your competitive edge. Watch total stack cost too: we regularly see $500 to $800 a month in app fees on mature stores, and replacing two or three overlapping apps with one custom feature is often cheaper by year two.

A one-page brief beats a 40-page requirements document: the business problem in plain words, who will use the system, the 5 to 10 workflows it must handle, the tools it must connect to, and your budget range and deadline driver. You do not need wireframes, a specification, or technical vocabulary; producing those is the agency's job during discovery. Stating a budget range up front is the single best move, because it gets you honest scoping instead of a quote engineered to win the meeting.

Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.

Neither is secure by default; security tracks the practices of whoever builds and operates the system, not the model. SaaS gives you the vendor's certifications and patching but puts your data in a shared multi-tenant platform on their terms, while custom gives you full control over data residency, access rules, and compliance requirements like HIPAA, with the responsibility sitting with you and your agency. Before hiring anyone for a system holding sensitive data, ask for their security checklist: encryption at rest and in transit, an OWASP Top 10 review, role-based access, and a penetration test before launch.

Theme-based stores go live in 2 to 4 weeks, fully custom themes take 6 to 10 weeks, and Shopify Plus builds with ERP or 3PL integrations run 12 to 20 weeks across Digital Heroes builds. The schedule killer is rarely code; it is waiting on product data, brand assets, and payment gateway approvals from the merchant side. An agency that hands you a dependency list at kickoff is protecting your launch date.

Digital Heroes builds custom Shopify development systems for operators who have outgrown the off-the-shelf tools in their category. The work is delivered remotely: our engineers work from Delhi and Lucknow, leadership is in New York, and some team members live in London and Sydney and work remotely from there. We have no office in Murfreesboro. You can chat with the team directly, and every form gets an email reply within 24 hours.
