Terms of Service

Last updated: 28 April 2025

These Terms of Service ("Terms") govern every consulting engagement between Vitalii Honchar ("Consultant", "we", "us", "our") and the entity or individual purchasing any packaged offer, retainer, or custom project ("Client", "you"). By booking a discovery call, signing a proposal, paying an invoice, or otherwise requesting our services, you agree to be bound by these Terms.

Plain‑English promise – we deliver well‑defined, outcome‑orientated technical work on time and on a fixed price or transparent day‑rate. You supply timely access, information, and decisions so we can move fast.

1. Definitions

DeliverablesTangible artefacts listed in the Engagement – e.g. C4 diagrams, cost models, PoC code, run‑books.
Fixed‑Fee PackageA pre‑defined offer advertised on our website (e.g. "3‑Day Perf Blitz") with price, scope, and timeline.
Day‑RateOur published consulting rate (€900 or €1 100 depending on urgency and seniority of work) plus up to 10 % buffer for incidental tasks.
Business DayA day other than Saturday, Sunday, or public holiday in Spain.

2. Scope of Services

  1. We will perform the Services described in the Engagement with reasonable care, skill and diligence consistent with industry best practice.
  2. Unless explicitly stated, Services do not include ongoing development, 24Ă—7 support, or managed hosting.
  3. Any item not in the written scope is a Change Request (see §8) and may adjust fees and schedule.

3. Engagement Process

  1. Discovery Call – complimentary 30‑min call to confirm pain points and select the best package.
  2. Proposal / SOW – emailed PDF summarising goals, scope, timeline, fees and key assumptions.
  3. Kick‑off – Client provides artefacts, accesses and a single point‑of‑contact ("Product Owner").
  4. Implementation – we execute the work; weekly async status note plus optional stand‑up.
  5. Review & Handover – walkthrough of Deliverables; one revisions cycle (≤ 3 minor tweaks) included.
  6. Follow‑Up – 14‑day e‑mail support window for clarifications.

4. Client Responsibilities

Failure to meet these responsibilities may extend timelines or incur additional fees.

5. Fees & Payment

  1. Fixed‑Fee Packages – 100 % payable upfront to secure calendar slot.
  2. Custom Projects / Retainers – billed on a milestone or monthly cycle at the Day‑Rate; 50 % deposit and 30‑day net terms on the balance unless otherwise agreed.
  3. Prices exclude VAT or any applicable taxes, which will be added to the invoice.
  4. Late payments accrue interest at 1 % per month (pro‑rata) plus any collection costs.

All fees are remote‑delivery by default. Pre‑approved travel or onsite work is invoiced at cost (economy class flights, mid‑range hotels, reasonable meals) plus 5 % administration.

7. Deliverables & Acceptance

8. Change Management

Requests to modify scope, priority, or timeline must be made in writing. We will respond with impact on schedule and cost. Work will not proceed until both parties approve the change.

  1. Both parties must keep confidential information secret and use it solely for the Engagement.
  2. Obligations survive for three (3) years after termination.

11. Data Protection

We process any personal data strictly as a processor under the EU GDPR, limited to what is necessary to perform the Services, and will sign a Data Processing Agreement on request.

12. Warranty & Disclaimer

13. Limitation of Liability

To the maximum extent permitted by law, our total aggregate liability under any Engagement shall not exceed the lesser of (a) the fees paid in the preceding twelve (12) months or (b) €50 000. We are not liable for indirect, consequential, loss of profit, revenue, data, or business interruption.

14. Term & Termination

  1. Each Engagement begins on the Effective Date stated in the proposal and ends upon delivery of all Deliverables or earlier termination.

Neither party is liable for delays caused by events beyond reasonable control, provided the affected party notifies the other and resumes performance promptly.

16. Governing Law & Jurisdiction

These Terms are governed by the laws of Spain. The courts of Madrid, Spain shall have exclusive jurisdiction, except we may seek injunctive relief in any jurisdiction.

17. Amendments

We may update these Terms by posting a revised version on our website. Changes apply to new Engagements only. Material changes will be highlighted at least fourteen (14) days in advance.

18. Notices

Legal notices must be sent by e‑mail to legal@vitaliihonchar.com and are deemed delivered on the next Business Day after sending.

19. Entire Agreement

These Terms together with any Proposal, SOW, or invoice constitute the entire agreement and supersede all prior understandings. If there is a conflict, the documents apply in this order: (1) Proposal/SOW, (2) these Terms, (3) any other attachment.


Acceptance, Payment & Limited Refund Guarantee

  1. Work Acceptance. Upon delivery of any milestone or final deliverable (collectively, "Work Product"), the Client will have five (5) calendar days ("Review Period") to review the Work Product and notify the Consultant in writing of any material deficiencies relative to the agreed scope.
  2. Payment Trigger. Payment for each milestone is due only after the Client provides written acceptance during the Review Period. If no written acceptance or rejection is received within five (5) days, the Work Product will be deemed accepted.
  3. Rectification Window. If the Client reports deficiencies during the Review Period, the Consultant will have a reasonable opportunity—no longer than ten (10) calendar days—to remediate the issues at no additional cost.
  4. Limited Refund Guarantee. If, after remediation, the Client remains dissatisfied and provides a written explanation within the Review Period, the Consultant will refund any amounts already paid for that specific milestone. This refund is the Client's sole and exclusive remedy for dissatisfaction with the Work Product.
  5. Exclusions. Refunds do not apply to (a) scope changes or new requirements introduced after project commencement, (b) delays caused by Client's failure to supply necessary information, access, or approvals, or (c) force‑majeure events as defined herein.
  6. Currency & Timeline. Refunds, when due, will be processed in the original payment currency within ten (10) business days of refund approval.
