Web3 Consulting Cost
Tomohiro Iida · Published July 11, 2026 · Updated July 11, 2026
Web3 consulting cost varies substantially by which phase you are commissioning and which contract type is used, so this article is not a market-average price guide. Using the prices Netsujo, a Kyoto-based Web3 development company, publishes as a first-hand data point, this piece covers the cost structure for early framing, PoC design, pre-procurement audit, and development, plus what to check when comparing quotes. Figures reflect Netsujo's own pricing as of July 11, 2026, and are not representative of other companies' rates.
Cost is set by phase and contract type
Web3 consulting cost is not a measure of service quality — it is set by which stage of evaluation you are commissioning and which contract type you choose. Web3 consulting means supporting a business, from the business's own standpoint, on whether to use blockchain, NFTs, or tokens at all, on technology selection, on designing a proof of concept, and on evaluating vendors — decisions made before building anything, distinct from the development itself.
| Factor | Effect on cost |
|---|---|
| Phase requested | Cost rises as you move from early framing to PoC design to development — each stage requires more work |
| Contract type | Fixed-price sets the amount; custom quotes vary with requirements |
| Legal / regulatory scope | Increases with the breadth of regulatory-relevant work, such as token design |
| Deliverable granularity | Verbal advice alone takes far less effort than a full document set usable for internal approval |
Netsujo's published prices (as of July 2026, excluding tax)
Netsujo offers early-framing-through-pre-procurement consulting at a fixed price of JPY 400,000–800,000, then switches to custom quotes from there on. The figures below are all published on Netsujo's own pricing page and are not a market average.
| Package | Price | Duration | Key deliverables |
|---|---|---|---|
| Web3 PoC design package | JPY 800,000 (excl. tax) | 4 weeks | Technology selection report, PoC design document (with KPIs and exit criteria), rough production-migration estimate, executive summary for internal approval |
| Smart contract pre-procurement audit package | JPY 400,000 (excl. tax) | 2 weeks | Design/GitHub structural analysis, a 40-item check report across 4 perspectives, a prioritized improvement list, handover material for a full audit |
| Custom-quote phase | Price range | Typical duration |
|---|---|---|
| Framing / requirements definition | JPY 500,000 – 2,000,000 | 2–4 weeks |
| PoC / prototype | JPY 2,000,000 – 8,000,000 | 1–3 months |
| MVP (limited release) | JPY 5,000,000 – 15,000,000 | 3–6 months |
| Full-scale development | JPY 15,000,000+ | 6 months – 1 year or more |
Within a package's stated scope, no extra charge applies; work outside that scope is quoted separately before it starts. Both packages cover design and audit work before production, and exclude PoC production implementation and a formal audit by a security-audit firm.
Contract types: fixed price vs. custom quote
| Aspect | Fixed price | Custom quote |
|---|---|---|
| Amount | Set in advance (e.g., JPY 800,000) | Presented once requirements are confirmed |
| Duration | Set in advance (e.g., 4 weeks) | Set per phase |
| Scope | Defined by the package | Defined individually through discovery calls |
| Fits | Internal-approval material, a first engagement | Confirmed requirements, longer-term work |
| Watch for | Anything outside scope is quoted separately | Total cost is not fixed before starting |
Netsujo connects the two by first building decision-making material through a fixed-price package, then moving into a custom-quoted development phase if the client decides to proceed — there is no obligation to continue past the package, and handover documentation for another vendor is also provided.
Payment terms and other costs (Netsujo's terms)
- Payment: standard is 50% on kickoff and 50% on acceptance, due within 30 days of invoicing (open to discussion).
- Tax: all listed prices exclude consumption tax.
- Travel: meetings within Kyoto or Osaka Prefecture are included; other areas are billed at actual cost.
- NDA: can be signed before the first consultation, using either Netsujo's template or the client's.
Four factors that affect cost
- Legal / regulatory scope — token issuance, sale, or distribution, or any question of crypto-asset classification, widens the review needed; Netsujo's fixed-price packages exclude formal legal opinions, which are commissioned separately with a lawyer or similar specialist when required.
- Whether a security audit is needed — putting a smart contract into production requires a separate formal audit by a security firm; Netsujo's JPY 400,000 pre-procurement audit finds design flaws early and hands off to that formal audit, rather than replacing it.
- Chain selection and technical requirements — public chain, consortium chain, or integration with existing systems each change the technical research and design effort involved.
- Deliverable granularity — "advice only" versus "a full document set usable for internal approval" can differ several-fold in effort on the same topic, which is why Netsujo's PoC design package extends beyond hearings to a technology report, design document, rough estimate, and an executive summary.
How to control cost
- Keep the first engagement to a fixed, small scope at the framing stage — Netsujo's free 30-minute consultation covers sorting out what actually needs deciding, moving to a paid package only once documentation is needed.
- Set exit criteria upfront — documenting KPIs and exit criteria at the PoC design stage prevents pouring in further budget without results; this is why Netsujo's PoC design document always includes exit criteria.
- Take deliverables in a form usable with another vendor — receiving handover-ready documentation keeps the option open to revisit the vendor at each phase.
7 items to check when comparing quotes
Comparing prices alone does not produce a real comparison if deliverables and scope of responsibility differ. Before committing, check the following seven items in the same format across every quote.
| Item | What to check |
|---|---|
| Purpose | Whether the work covers research, decision support, design, or implementation |
| Deliverables | Verbal advice, or documents usable for internal approval, an RFP, or handover |
| Exclusions | What is not included — a legal opinion, a formal audit, production development |
| Duration | Whether it includes discovery, review, and acceptance |
| Additional cost | The rule for quoting scope changes |
| Rights / handover | Whether deliverables can be used with another vendor or internally |
| Decision criteria | Whether PoC KPIs, exit criteria, and next-phase conditions are defined |
Frequently asked questions
- Is there a monthly retainer contract?
- Netsujo's Web3 consulting is offered as fixed-price packages and phased custom quotes, not a fixed monthly retainer. Where ongoing involvement is needed, it is designed as a custom quote broken into phases. Since retainer contracts differ by company, when comparing, check what a monthly fee actually includes, deliverable by deliverable.
- A quote came back higher than expected — where can it be trimmed?
- What to trim is scope, not price. Check three things: narrowing the target use case to one, limiting deliverables to what is needed for the decision at hand, and separating out specialist work such as legal review or a formal audit to a later phase. Splitting the work into phases and deciding on the next one only after seeing the first phase's results also keeps early spending down.
- Should consulting cost and development cost be budgeted separately?
- Yes. In Netsujo's case, framing-through-pre-procurement consulting (fixed-price packages at JPY 400,000–800,000, or a custom framing/requirements quote around JPY 500,000–2,000,000) and development from PoC implementation onward (from around JPY 2,000,000) differ by an order of magnitude and go through different internal approval processes. Budgeting the framing phase first, then using its output — including a rough estimate and exit criteria — as the basis for approving development budget, tends to work better in practice.
