According to McKinsey and several European insurance associations, 45–60% of IT projects run over budget or fall behind schedule, and up to a third of digital initiatives stop halfway without a clear ROI. The most paradoxical thing is that in most cases the cause isn’t a “complex technology” but incorrect questions at the outset and a weak contract. How many times have you seen a studio’s beautiful presentation, and six months later: a blinking loader instead of a metrics report?
Asking the right questions of a web studio before signing a contract is not a formality but your risk-management tool: from rights to the source code to SLA and warranty periods. I’m convinced: a well-drafted contract saves more than any haggling over a discount. In this article I’ve compiled a practical guide and checklist based on the experience of BUSINESS SITE since 2011: from pharmaceuticals and laboratory chains to e-commerce and financial services, where we integrated CRM, PrivatBank/Monobank payments, Nova Poshta delivery and marketplaces like Rozetka and Prom.ua.
If you want transparent budgets, predictable timelines and measurable ROI – read the material to the end. I’ll lay out what to ask a web studio before signing a contract, how to vet a web studio before signing the contract, and which mandatory contract clauses with a web studio will protect your business when it matters most.
Questions for the web studio before signing the contract
Start with prioritization. Create two blocks: go/no‑go decisions and clarifying requests. The first block closes risks: ownership of the code and IP assignment clause, SLA and warranty periods in the website development contract, terms of support and maintenance after site launch, security and GDPR/CCPA compliance, budget and payment schedule. The second block clarifies details: version control, repository and source protection (Git), backup and data recovery policy, testing, QA and acceptance of work, integrations and analytics.
I usually advise documenting the studio’s answers in writing: a short meeting protocol and a recording of the video call, plus requested documents, the contract template, a sample technical specification with acceptance criteria, a sample SLA report, and references with contacts. This speeds up comparing vendors and reduces the risk of losing agreements. For objectivity, it is useful to score each checklist item on a scale of 0–2 and calculate the final score.
Check the web studio before signing
Case studies and relevant projects — the basics. Ask not for a ‘pretty picture’ but for facts: goals, KPIs (conversion rate, CAC, LTV, retention, uptime), initial constraints, stack, timelines and numeric results. In projects for pharma retail our team, for example, proved relevance through metrics: growth of organic traffic after migration with zero loss in seo, reduction of order TTL thanks to integration with “Nova Poshta”, increase in CR in the cart after optimizing Core Web Vitals.
Financial and legal due diligence increases predictability. Check the company’s legal registration, the presence of professional liability insurance, financial guarantees and measures to ensure performance of obligations. Reputation is confirmed by reviews and independent references. I recommend a short interview with a former client of the studio: ask how force majeure events were handled, how change requests were processed and what happened at the acceptance stage.
Website development contract: what to include
Fix the scope of work through a detailed TOR: deliverables, functional and non-functional requirements, work acceptance criteria, performance metrics, clear acceptance criteria. For integrations: contract testing of APIs (OpenAPI/Swagger), authentication schemes (OAuth2, JWT, SSO), roles and responsibilities of the parties.
Tie the timeline and development stages in the contract with the web studio to milestones with specific dates and artifacts: prototypes, mockups, demos, staging release, production release. Additionally specify consequences for missed deadlines: budget reallocation, complimentary hours or compensations. Draft payment terms and invoicing stages in the contract taking into account withholdings until release and verified acceptance (sign‑off).
Be sure to include a support section: warranty period and free fixes after launch, defect classification and SLA boundaries. For scope changes provide a change request: request form, estimation, impact on timeline and cost, prioritization rule. In our experience, a transparent CR process reduces conflicts and keeps the burn rate under control.
Liability, penalties and termination
Formulate the terms of penalties and compensation in case of KPI/deadline breaches: a fixed penalty, a discount on subsequent stages, an extension of the warranty period. Specify force majeure and the procedure for documentary proof so that both parties understand how to act in case of external disruptions. Transfer of rights upon contract termination should be included as a separate clause: the handover of source code, documentation and accesses takes place before the final reconciliation.
Source code rights
Source code rights and intellectual property in the contract: a key section. Specify ownership of the code, IP assignment clause and transfer of ownership after full payment. Record that the contractor transfers exclusive rights, and the customer receives the right to use without territorial or time limitations.
Clearly separate components with open licenses (OSS) and proprietary code. The studio must notify about third-party libraries and their licenses, and also ensure license compatibility. In e‑commerce BUSINESS SITE cases, this helped the client seamlessly scale the project and attract external developers without legal barriers.
Licensing of third-party and open source
Specify the licensing of third-party libraries and open-source software in the project: MIT/Apache – allow commercial use provided notices are preserved, GPL: requires distributing derivatives under GPL terms. The contractor’s liability for license violations is defined in the indemnification clause: the contractor compensates for damages if they used an incompatible license or violated distribution terms.
SLA and warranty periods for website development
SLA and warranty periods in a website development contract rely on SLI/SLO and clear SLA metrics. Specify uptime % (for example, 99.9% for the production environment), response time (RTT), mean time to restore (MTTR) and target mean time between failures (MTBF). For multiregional clients it is appropriate to specify on-call coverage hours and an escalation procedure.
Classify defects: critical (payment/cart/login outage), major (partial functionality), cosmetic (UI issues). For each category define timeframes for fixes: critical — hotfix within 2–4 hours, major — in the next release slot, cosmetic — in a scheduled release. In projects for the travel and construction industries this approach minimized business damage during peak sales.
Define RTO and RPO, add a business continuity and disaster recovery plan: backup frequency, test restores, incident logs and a runbook. Specify penalties for SLA breaches, including a credit for support hours or a discount in the next billing period. BUSINESS SITE’s practice has shown that transparent SLA reporting builds trust and makes scaling predictable.
Monitoring availability metrics
Include SLI/SLO and availability metrics in the contract: uptime %, MTTR, error rate, time to detect. Specify monitoring tools: APM and tracing (for example, Datadog, New Relic, Prometheus/Grafana), alerting via Sentry, integration with chat notifications. The client gets access to dashboards and monthly reports with findings and improvement actions.
Website support after launch
Choose a support model: a fixed retainer with SLA packages, time&materials billed per ticket, or a hybrid model. For each option, specify ticket priorities, timeframes for fixing critical bugs, the release window and the communication protocol. The warranty period and free post-launch fixes should be included in a separate section describing which categories of defects are covered.
Timeline and development stages
Break the project into phases: discovery (research, roadmap, architecture), prototyping (UX/UI, clickable prototype), MVP, release, post‑launch. At each stage describe artifacts, risks and readiness criteria (definition of done). For acceptance, establish the process: acceptance tests, QA checklist, sign‑off process and a window for regression checks.
Load testing
Include load testing: load, stress and soak tests, define a performance budget and target Core Web Vitals (LCP, CLS, INP). Commission a report with profiling, a list of bottlenecks and an optimization plan. Performance guarantees include SLOs for API response time and budgets for static assets, CDN and edge‑caching.
Invoicing: payments and risks
Compare models: fixed price vs time & materials vs retainer. Fixed price provides predictability but requires a strict scope and discipline for change requests; T&M provides flexibility and fast response; a retainer is optimal for long-term support and development. In the contract, specify the invoicing stages, holdbacks until acceptance and the payment procedure with acceptance certificates.
Financial guarantees of obligation fulfillment and performance security improve protection: deposit, bank guarantee, milestone‑hold. Manage the project budget via burn rate, sprint reports and approval of additional work. This approach helped one of our finance clients keep NPV within the planned corridor while scaling CRM integrations.
Audit, pentest, regulatory compliance
Security audits and pentest requirements before release include scope, timeline and a window for fixes. The contractor must take into account OWASP Top 10, implement security headers, CSP, DDoS protection with WAF and rate limiting. For payment integrations comply with PCI DSS, and for personal data, comply with GDPR/CCPA, consent management, cookie banner and storage of consents.
Certificate management SSL/TLS should be recorded in the contract: key rotation, monitoring of expiry dates, HSTS and automated issuance. Logging via centralized ELK/EFK stack, APM and alerting on vulnerabilities with prioritization. On the BUSINESS SITE we add a vulnerability scan response procedure: deadlines for fixes by severity and a closure report.
Backups and recovery plans (DR)
Briefly describe the backup and data recovery policy: frequency (snapshots/full/incremental), geo-distribution, encryption. Schedule test recoveries to verify RTO/RPO in practice. The disaster recovery procedure should include responsible parties, action checklists and verification of backup restoration.
Integrations, analytics, and SEO during migration
Document the contractor’s responsibility for integrations with CRM, CDP and external services in the responsibility area. API format, third‑party providers’ SLAs, retry queues, failure monitoring. For payments – integrations with PrivatBank/Monobank and local providers, for logistics: Nova Poshta, for marketplaces – Rozetka/Prom.ua.
SEO migration: a separate subproject: migrating old content, URL mapping, 301 redirects, canonicals, preserving metadata, structured data and schema.org. Record responsibility for SEO and redirects during the site migration, as well as post‑migration checks: indexation verification, ranking monitoring, speed regression tests. In e‑commerce cases, for a BUSINESS SITE, such a checklist helped preserve traffic and maintain conversion.
Analytics, GA4, a correct dataLayer, GTM, events and validation during QA. The contract should include a set of dashboards, channel attribution rules and the reporting cadence. Additionally, it’s useful to plan a CRO stage: A/B tests, personalization and growth hypotheses.
Repository, version control and CI/CD
Require access to the code repository, a permissions policy, MFA, branch rules, semantic versioning and release tagging. Describe code quality mechanisms and code review formally: number of approvals, linters, unit coverage, contract testing for OpenAPI/Swagger. For CI/CD provide specifics: GitLab CI, GitHub Actions or Jenkins, canary releases and blue‑green deployments.
Deployment automation and staging/production parity reduce release risks. Rollback procedures and recovery points include verification of DB migrations and feature flags. A library update policy and CVE scanning of dependencies are mandatory; specify the tools, frequency and reporting on remediated vulnerabilities.
Access transfer, handover and training
Formally describe the transfer of the domain, hosting accounts, DNS, administrator rights and documentation sets. Specify who and how will manage the test and production environments after the release, and how temporary access is issued to contractors. Include architectural documentation, runbook, deployment instructions, integration diagrams and the internal wiki in the handover.
Client team training consists of recorded sessions, Q&A and a knowledge transfer plan. We at BUSINESS SITE run practical workshops for marketers and support teams: from GA4/GTM‑events to release management procedures. Finish the project with a final check: an acceptance checklist, transfer of rights and signed acts.
Assessment of project risks, metrics, TCO and ROI
Define success metrics and KPIs: conversion rate, CAC, LTV, retention, uptime, performance (Core Web Vitals), feature release velocity. Establish regular reporting: dashboards, meeting cadence, a set of required metrics and hypotheses. Include threshold values and a compensation mechanism in the contract if KPIs are not met due to the contractor’s fault.
The solution we developed in BUSINESS SITE for online retail showed: discipline around TCO and the roadmap reduces ad-hoc spending by 20–25%.
Privacy and indemnification
The privacy terms and NDA signing describe which data are protected, access levels, and retention periods. For personal data, add a DPA and processing requirements. Standard liability limitations and indemnification set the scope of risks and allocation of responsibility for licenses, security, and third parties.
BUSINESS SITE specialists recommend wording with an emphasis on transparency: clear triggers, clear timelines, and verifiable artifacts.
Frequently Asked Questions
Answer: Use a checklist: rights to the code and an IP assignment clause, SLA and warranty periods, support and maintenance terms, development timelines and milestones with acceptance criteria, payment terms and invoicing schedule, backup and data recovery policy, testing and acceptance of deliverables, security and compliance with GDPR/CCPA, access to the task tracker and communication protocol.
Answer: A direct statement of code ownership, an IP assignment clause, transfer of ownership after payment, a list of exceptions for OSS, the contractor’s obligation to disclose licenses, and optionally a source code escrow with the sources held by a third party and a schedule for updating the escrow.
Answer: Define SLI/SLOs: uptime %, response time, MTTR. A critical defect is the outage of key functions (payment, login, checkout); response time measured in hours, fix — immediate hotfix. Major and cosmetic defects: handled with separate release windows and timelines.
Answer: Make contractor responsibility explicit in the contract: migration of legacy content, URL mapping, 301 redirects, canonical tags, preservation of metadata and structured data. Additionally include a post-migration indexing audit and traffic monitoring with reporting.
Answer: Escrow is appropriate for high business-risk projects: finance, pharma, large e-commerce. Organization should include selecting a trusted custodian, rules for replenishing the escrow (releases/sprints), a list of artifacts and clear release conditions in case of an SLA breach or cessation of work.
Conclusion and CTA
Pre-signing summary: check the tech stack and processes (CI/CD, QA, code-review), code ownership and IP assignment clause, SLA and warranty periods with clear SLI/SLO, security and compliance with GDPR/CCPA, payment terms and support, as well as handover and training for your team. This approach turns the contract into a working tool for managing timelines, quality and ROI, rather than a formality.
