The No-Bullshit Guarantee
Money back, no questions asked. Retainers cover the latest paid week. Fixed-price work covers the milestone agreed in your signed offer or statement of work. This is not an automatic refund of an entire project. Prepaid developer hours are a separate offer with their own published terms.
// Agent commerce
The same offers for you and your AI agent
People and authorized AI agents can buy the same services at the same prices and conditions. Agents use machine-readable offers, deterministic VAT quotes and MPP or x402. After successful payment, delivery can start as early as the next day; an intro or kick-off call is recommended, but optional.

Optional Fast Lane
Need it sooner? Book a date we have to hit.
Get more agreed delivery into the same week, or the same scope completed sooner, through additional reserved capacity and parallel execution. Testing and acceptance stay the same. Eligible milestones can take about 1/3 to 1/2 of the standard quoted time. Miss the agreed date and we refund 100% of its surcharge.
Show the outcome
Date met
You get the agreed scope, tested and accepted, on the Fast Lane date. That date is what the surcharge pays for.
Date missed
100% of the Fast Lane surcharge goes back to you within 10 business days of the missed date. No dissatisfaction claim, no correction cycle first. Delivery continues and all your other rights stay.
- Same scope, testing and acceptance criteria
- One exact Fast Lane date, in writing
- Date missed: 100% of the surcharge back
- Base price and existing guarantees unchanged
The Fast Lane surcharge is a separate line in your offer, agreed before you book.
Eligibility and full Fast Lane terms
Written down before you book
- Standard schedule for the milestone
- Booked start date, with everything needed to begin ready
- Exact Fast Lane deadline
- Deliverables and acceptance criteria
- Fast Lane surcharge
- Dependencies on your side and on third-party vendors
When Fast Lane is available
We check scope, inputs, dependencies and team capacity before reserving a Fast Lane slot. We agree an earlier date only when the same testing and acceptance fit.
When the date can move
Blocked client or agreed vendor inputs, or a change of scope, can move only the affected delivery date, openly and by agreement. Our staffing or overbooking never moves it.
What Fast Lane never compresses
Required observation windows, security and QA checks, vendor lead times and exploratory research run at their real length. We plan the Fast Lane date around them and never promise to shorten them.
The refund
Miss the agreed Fast Lane date and we refund 100% of its surcharge within 10 business days of that date. No dissatisfaction claim or correction cycle is required. This refund covers the Fast Lane surcharge; the base project fee keeps its existing guarantees. Business days are Monday to Friday, excluding Austrian public holidays (Europe/Vienna).
Everything else stays
Base delivery continues, and your acceptance rights and our existing satisfaction and acceptance guarantees apply unchanged. Fast Lane buys an earlier date, never a lighter finish.
Ask about a Fast Lane date
We check feasibility first, then quote the surcharge with an exact date.
A fixed price for the next business milestone
These are additions to the right core engagement. A free readiness check of existing material confirms fit, scope and a booked start. Unknown systems need a separate assessment. All prices are net; applicable tax is additional.
One-off package: the acceptance and fee-protection milestones below apply. Weekly-retainer and Fast Lane terms belong to their own engagements.
Enterprise buyer review
A forwardable response for one real enterprise prospect.
First response: 10 business days from the booked ready start.
€2,500
net, one-off
- One known product; up to 40 substantive questions, counting subquestions separately.
- Architecture/data flows, evidence links and a prioritized gap plan.
- One technical call up to 45 minutes and one consolidated revision.
Before booking: Your actual questionnaire, current policies, disclosure approval and a decision owner. The free check confirms the system is familiar and the evidence sufficient; a mostly unknown estate needs assessment.
Payment milestones: €2,000 for the accepted response/evidence pack; €500 for the agreed call/revision obligations. Unused optional call/revision capacity closes at the feedback deadline.
Related delivery: Twinsoft AI. Hardened a product for enterprise pilot conversations.
Scope, acceptance and fee protection
What earns the fee: Every agreed question is supported or explicitly unknown, not implemented or client-owned. Gaps have owners and next actions. Request the revision within 10 business days; we return it within 5 business days of consolidated feedback.
Scope limits: Policy creation, penetration tests, certification, legal opinions, remediation and buyer-added questions are separate. You approve submission. The prospect controls approval and the sale.
By prior written agreement, the €500 enterprise completion milestone can instead be earned only when the named prospect confirms its technical review is complete within 60 calendar days of the response. No event means no outcome fee. It covers only the agreed call/revision, not unlimited support or a guaranteed sale.
Your agreed milestone is corrected once within 5 business days. If it still fails, its unearned fee is waived or prepaid unearned amounts refunded within 10 business days. If Wavect’s failure makes the whole package unusable, we refund the whole package within the same 10 business days after that correction opportunity. Scope, acceptance and any client/vendor waiting are recorded before booking; we show the reason and revised date when a dependency pauses the affected clock. These package terms are written into your scope and preserve your existing rights. For these packages, business days are Monday to Friday excluding Austrian public holidays; dates use Europe/Vienna. Separately, our satisfaction guarantee covers the agreed fixed-price milestone: its fee is refunded if you are not satisfied, without requiring an explanation.
One-off package: the acceptance and fee-protection milestones below apply. Weekly-retainer and Fast Lane terms belong to their own engagements.
Workflow adoption and retirement
A real team uses the replacement and stops the agreed duplicate step.
10 business days of observation from the supervised first run; one correction cycle.
€4,000
net, one-off
- One already working replacement, one workflow, up to 5 users and 2 systems.
- Up to 100 representative records, 2 existing data shapes and 20 agreed cases.
- Baseline, sample setup, observation, reconciliation, archive instructions and retirement decision.
Before booking: A daily-use workflow, accessible data, nominated users, authorized process owner and an existing proportionate recovery route. The software build is separate.
Payment milestones: €3,200 for the independently usable, accepted transition/observation pack; €800 earned only on evidenced, authorized retirement. A blocked retirement or insufficient participation leaves that outcome fee unearned.
Related delivery: MyMerch. Automated manual delivery steps in an existing Shopify business.
Scope, acceptance and fee protection
What earns the fee: Agreed cases reconcile, nominated users finish the job, required records remain accessible and the owner approves stopping the named old step after validation and recovery conditions. If evidence or approval is missing, retirement remains blocked.
Scope limits: Large migration, data repair, new integrations, licenses and material engineering are separate. Retain the old route until safe, including reconciliation of writes after cutover. One correction cycle of up to 5 additional business days; then close or agree new scope.
A fee tied to a result you can verify
For eligible cost-retirement work, €800 of the €4,000 workflow fee is earned only when the agreed net recurring cost reduction is verified by an invoice or effective cancellation within 60 calendar days after observation. The baseline, reduction threshold and new operating costs are agreed before purchase. Eligibility requires conservative forecast 12-month net cash savings of at least 2 times all one-time change costs, including any build. This replaces the retirement milestone, never adds to it. Released staff capacity is recorded separately; no verified event means no outcome fee.
Your agreed milestone is corrected once within 5 business days. If it still fails, its unearned fee is waived or prepaid unearned amounts refunded within 10 business days. If Wavect’s failure makes the whole package unusable, we refund the whole package within the same 10 business days after that correction opportunity. Scope, acceptance and any client/vendor waiting are recorded before booking; we show the reason and revised date when a dependency pauses the affected clock. These package terms are written into your scope and preserve your existing rights. For these packages, business days are Monday to Friday excluding Austrian public holidays; dates use Europe/Vienna. Separately, our satisfaction guarantee covers the agreed fixed-price milestone: its fee is refunded if you are not satisfied, without requiring an explanation.
One-off package: the acceptance and fee-protection milestones below apply. Weekly-retainer and Fast Lane terms belong to their own engagements.
Operational independence exercise
Another competent operator proves they can run the agreed tasks.
Within 5 business days of the booked ready start and operator slot.
€1,250
net, one-off
- One skilled receiving operator; one service, environment and existing data source.
- Clean setup, staging deployment, existing restore/export and one routine configuration/content change.
- Up to 1 GB disposable sample; session up to 90 minutes; one correction/retest.
Before booking: A known system with working setup, deploy and recovery procedures, authorized access and an operator with the agreed baseline skills.
Payment milestones: €1,000 for accepted preparation and corrected instructions; €250 earned on the successful agreed rehearsal.
Related delivery: IKB. Handed the platform over to the in-house team and remained available as external support.
Scope, acceptance and fee protection
What earns the fee: The agreed tasks pass using corrected, client-owned instructions without hidden author knowledge. We record hints, permissions, remaining gaps and whether the receiver is a Wavect substitute or external operator.
Scope limits: New backup infrastructure, broken deployment repair, novice training and complex recovery investigation are separate. Baseline handover already owed under a build is not charged again.
Your agreed milestone is corrected once within 5 business days. If it still fails, its unearned fee is waived or prepaid unearned amounts refunded within 10 business days. If Wavect’s failure makes the whole package unusable, we refund the whole package within the same 10 business days after that correction opportunity. Scope, acceptance and any client/vendor waiting are recorded before booking; we show the reason and revised date when a dependency pauses the affected clock. These package terms are written into your scope and preserve your existing rights. For these packages, business days are Monday to Friday excluding Austrian public holidays; dates use Europe/Vienna. Separately, our satisfaction guarantee covers the agreed fixed-price milestone: its fee is refunded if you are not satisfied, without requiring an explanation.
Other bounded additions
Journey protection and recovery exercises have fixed scopes on their service pages. First-use observation and hiring support are selective additions, not mandatory extras. Qualifying dependency work is quoted after readiness. Competent acceptance, source ownership and usable handover remain part of core delivery.
ILLUSTRATIVE ACCEPTANCE CARD
A proposal workflow, ready for real work.
An example of what to agree before a build. This is a sample, not a client result.
- Useful result
- A nominated operator creates a proposal from approved data.
- Proof
- Valid and invalid cases reconcile in the agreed version and environment.
- First use
- Record assisted completion and later unassisted repeat use separately.
- Independence
- The operator changes one template and follows the recovery instructions.
- Old work ends
- The owner approves retirement after reconciliation and the recovery window.
A budget for bugs. A price for accepted results.
For a working app, including a vibe-coded one: choose a bounded functional test pass, optional accepted findings and separately approved repairs. Set the spending limit before work starts.
Your ceiling comes first
Coverage + up to 5 accepted findings: at most €1,500. Repairs need a separately approved quote within your total cap. Unused authorization is not invoiced.
Test the agreed scope
€750
One coverage pass across up to 12 agreed scenarios and 3 journeys. You receive the results even when no bug is found.
Per accepted finding
€150
One material, reproducible defect. Same root cause or same corrective change: one fee. Severity changes priority, never this price.
Per accepted repair
- Small
- €600
- Standard
- €1,200
Eligible small repair: €600. Standard repair: €1,200. An already paid €150 finding fee is credited toward that repair.
Already know the bug? For a bug you can reproduce, request a repair-only quote. No finding fee; a coverage pass is needed only if separately agreed.
Net prices; applicable tax is additional. One-off scope with its own correction/refund terms; an alternative to weekly QA for the same work.
Pricing FAQs
What founders ask before they sign. Front-loaded answers.
Because hourly billing pays us to be slow and punishes us for being good. Retainers and fixed prices align our incentive with shipping. The one place hours still matter is scope honesty: we say no to fixed price when the scope is genuinely uncertain, and run a Discovery (EUR 3,500 fixed, 2 to 3 weeks) instead.
Werkvertrag for fixed-price work (Tech Due Diligence, Discovery, fixed-price builds): we are legally bound on scope and deliverables, not hours. Dienstvertrag-style retainer for CTO-on-Call, Embedded Fractional CTO, Co-Founder, and QA: a rolling weekly commitment you cancel without notice. Both issued by Wavect GmbH (FN 575337i, Ampass, Tirol).
Retainers can be cancelled weekly without notice. If we do not blow you away, we refund the latest paid week, no questions asked. The same satisfaction guarantee covers the fixed-price milestone agreed in your signed offer or statement of work. Contact us to request the applicable refund; payment and milestone details identify the amount. The whole project is not automatically refunded. Prepaid developer hours keep their separate published terms.
EUR by default, USD or CHF on request. Austrian clients pay 20 percent VAT. EU B2B clients with a valid VAT-ID pay zero (reverse charge). Non-EU clients pay zero VAT. Payment terms are 14 days net by default, 30 for enterprise. Bank transfer, SEPA, Wise, and Stripe.
No. Cash only. Trading consulting hours for equity creates a misaligned incentive, an awkward cap-table line, and a difficult conversation when the engagement ends. If you want skin-in-the-game ownership, hire a full-time CTO. If you want an operator who is unambiguously on your side because you pay the invoice, that is us.
Yes. The EUR 3,500 Discovery fee is credited in full against the build invoice if you continue with us. If you take the roadmap and build elsewhere, you keep everything we produced and owe nothing further. The Discovery ends with a fixed-price offer, not a sales pitch.
Our CTO-on-Call tier starts at EUR 2,500 per month, the Embedded tier at EUR 12,000 per month for 1 to 2 days a week. A full-time senior CTO in Austria costs roughly 12 to 18k per month in salary alone before equity, recruiting, and onboarding time. Fractional is not a discount full-timer: it is the right shape when you need the authority but not the presence.
