Quick answer
Shopify AI builds at Braincuber run 4-12 weeks and cost $1,200 to $35,000 depending on scope. A focused chatbot ships in 4-6 weeks for $1,200-$3,500. A multi-channel AI agent with Shopify + Klaviyo + ShipStation integrations ships in 8-12 weeks for $15,000-$35,000. Payback ranges 7-14 weeks across the 18 builds we shipped between 2024-2026. Every engagement starts with a two-week paid discovery ($4,500) that you keep if you do not move forward.
The 6 phases of every Shopify AI build
Every engagement we ship follows the same six-phase pattern. The phase lengths flex with scope; the phases themselves do not.
- Discovery (2 weeks, $4,500 fixed). We sit with your CS lead, your CX lead, and your founder. We tag 200 anonymized tickets, list the top-10 ticket types, map them to data sources. The deliverable is a 20-page scoping document with a fixed-price recommendation. If you do not move forward, the document is yours to take anywhere.
- Eval set + architecture (1-2 weeks). Your CS lead labels 200 tickets across the chosen categories with the correct response and the correct tool call. This is the eval set. We do not write a single prompt until the eval set is approved.
- Build (3-8 weeks depending on scope). Tool wiring (Shopify Admin API, Klaviyo, Recharge, Front), prompt iteration, model selection (GPT-4o vs Claude Sonnet 4.7 — we benchmark both). Every prompt change is scored against the eval set.
- Shadow mode (1-2 weeks). Agent runs against every incoming ticket in parallel with your humans. We compare agent-suggested response vs human-actual response daily. Disagreements drive prompt patches.
- Gated rollout (1-2 weeks). 10% → 50% → 100% traffic over 10-14 days. Hard rollback criteria written before traffic flips.
- 90-day SLA + tuning. Daily eval review, weekly prompt patches, monthly cost review. Named PM in EST. We do not ghost after launch.
The four price tiers, with real client data
| Tier | Scope | Price | Timeline |
|---|---|---|---|
| Focused chatbot | Top-3 ticket types, 1 integration (Shopify only) | $1,200 - $3,500 | 4-6 weeks |
| Multi-flow agent | Top-10 ticket types, 2-3 integrations | $8,000 - $15,000 | 6-9 weeks |
| Full operations agent | Support + recommendations + recovery flows, 4-6 integrations | $15,000 - $35,000 | 8-12 weeks |
| Enterprise / Shopify Plus | Multi-store, SOC 2 scope, dedicated PM | $35,000+ | 12+ weeks |
Across the 18 builds we shipped between September 2024 and April 2026, the median fell in the multi-flow agent range. Payback measured at 9 weeks median, 7-14 weeks range. Brands in the focused-chatbot tier paid back faster but had a smaller absolute savings number.

Most agencies sell free discovery and bury the real work in the build. We do the opposite. The two-week paid discovery is the most useful $4,500 we will ever ask you for, and you keep the output even if we never work together.
- Top-10 ticket-type breakdown with volume + automation feasibility for each.
- Architecture diagram — data sources, tool definitions, model choice, hosting decisions.
- Eval-set spec — what your CS lead needs to label and how.
- Fixed-price quote for the build, broken down by phase.
- Risk register — what could go wrong, what our rollback plan is.
- Reference architecture you can hand to a competing agency for a price-check quote.
What stops a Shopify AI build from succeeding
We have walked away from three engagements in the last 18 months. Same three reasons each time:
- Data scattered across spreadsheets. If your order data lives in Shopify but your returns flow lives in a Notion doc and your subscription details live in a CSV emailed to the founder weekly, the agent has no clean source of truth. Fix the data first.
- No one will own the eval set. The CS lead has to commit to labeling 200 tickets in the first 10 days. If that ownership is fuzzy, the build will not ship a quality product.
- "It needs to be perfect day one." The right metric is automation rate + CSAT not changing. A first launch at 56% automation that climbs to 64% over 90 days beats a delayed launch chasing 90%.
FAQ
Why a paid discovery?
Free discovery is sales theater. The discovery output is real architecture work — 20 pages, 10 sources, a fixed-price scope. We charge $4,500 because it costs us about $4,500 in senior time, and we want only buyers who treat it as real planning.
Do you do Shopify themes too?
Yes, but the AI engagement is separate. If you need both, we scope them as two engagements with shared discovery. See our Shopify development services hub.
Can we phase the engagement?
Yes. Most clients start with the focused-chatbot tier ($1,200-$3,500), see real numbers in 6 weeks, then expand into the multi-flow tier. Each phase has a fixed price and can be paused without affecting prior phases.
What about Shopify Plus vs Basic?
The build pattern is identical. Plus stores typically have more integrations in scope (Recharge, Loop, Reviews) which pushes them into the multi-flow or full-ops tier. Basic stores with simple flows often fit the focused-chatbot tier.

Methodology
Build counts, timelines, and payback figures come from 18 Shopify AI engagements shipped between September 2024 and April 2026. Prices reflect our published 2026 rate card; previous engagements may have been priced 5-15% lower or higher depending on scope drift. Median payback (9 weeks) calculated as months until accumulated savings exceed build cost, measured on signed client invoice data. Industry benchmarks for AI-driven CS deflection cross-referenced against the Forrester Total Economic Impact study on AI support, the Deloitte State of AI 2026 report, and the OneReach.ai 2026 benchmark of 5.1-month median payback across all AI agent categories.
