The Software-as-a-Service (SaaS) business model relies on continuous, recurring subscription payments. When enterprise customers or corporate subscribers located in Türkiye default on multi-year contracts, usage-based fees, or recurring subscription invoices, foreign SaaS vendors encounter unique cross-border legal challenges.
Navigating the recovery of SaaS subscription debts requires a solid understanding of digital service contracts, foreign currency enforcement, procedural debt collection under Turkish law, and local tax compliance considerations. This guide provides a detailed analysis of the legal mechanisms, procedural steps, and strategic choices available to foreign SaaS providers seeking to collect unpaid subscription fees from Turkish commercial counterparties.
1. Legal Characterization of SaaS Contracts under Turkish Law
To enforce a debt in Turkish courts or execution offices, the underlying obligation must be properly classified under the Turkish Code of Obligations (Law No. 6098 – “TCO”).
Nominate vs. Innominate Contracts
SaaS agreements do not fit neatly into traditional nominate contracts explicitly codified in the TCO (such as sales, lease, or work contracts). Instead, Turkish jurisprudence categorizes SaaS agreements as innominate or mixed-type contracts (isimsiz / karma sözleşme), combining elements of:
- Lease Agreements (Kira Sözleşmesi): Temporary granting of access and use of software infrastructure hosted on remote servers (TCO Art. 299).
- Service / Work Agreements (Hizmet / Eser Sözleşmesi): Maintenance, technical support, server uptime commitments, data security, and software updates (TCO Art. 393 & Art. 470).
Digital Terms of Service and Electronic Signatures
Foreign SaaS vendors typically onboard Turkish corporate clients through online click-through agreements (click-wrap / browse-wrap), electronic order forms, or customized master service agreements (MSAs).
- Validity of Electronic Contracts: Under Article 1 of the TCO, contracts are formed upon the mutual and harmonious expression of the parties’ intent. Electronic acceptances (e.g., clicking “I Agree,” digital signatures, or confirmation via email) are valid under Turkish contract law.
- Evidentiary Weight: Under Law No. 5070 on Electronic Signatures, a qualified electronic signature carries the same evidentiary weight as a handwritten signature. Simple electronic acceptances are contractually binding and constitute documentary evidence (belge) under the Turkish Civil Procedure Code (Law No. 6100 – “CPC”). Foreign SaaS companies should log IP addresses, timestamp confirmations, user login credentials, and email trails as supporting evidence to resist potential debt denials.
2. Pre-Litigation Enforcement and Account Management Strategies
Before initiating judicial enforcement, foreign SaaS providers should deploy contract-level remedies and administrative collection efforts.
Contractual Suspension of Access (Digital Self-Help)
Unlike physical product sellers who cannot easily repossess delivered goods, SaaS platforms possess a distinct advantage: the ability to restrict or terminate access to the cloud environment.
- Legal Permissibility (Ödemezlik Def’i): Under Article 97 of the TCO (the defense of non-performance), a party to a bilateral contract is not obligated to perform its obligation if the counterparty has failed to perform its due obligation.
- Contractual Provision: The MSA should explicitly reserve the SaaS provider’s right to suspend account access, throttle API limits, or restrict user licenses upon a payment default exceeding a set period (e.g., 14 days), without incurring liability for business interruption or data loss.
- Proportionality and Notice: Deleting customer data abruptly without adequate warning can trigger claims for damages under Turkish tort law or the Law on Protection of Personal Data (KVKK Law No. 6698). Before terminating access or deleting user data, the vendor should issue an electronic default notice giving a final grace period.
Issuing a Formal Notarial Default Notice (İhtarname)
To transition from informal account management to formal legal action, the creditor must place the debtor in legal default (temerrüt).
- Notary Service: Sending a formal notice via a Turkish Public Notary (Noter) provides conclusive proof of delivery and timestamping under Turkish law.
- Content: The notice must set out the contractual default, itemize the outstanding subscription invoices, demand payment within a specified period (typically 7 to 14 days), and declare that failure to pay will result in legal proceedings, contract termination, and interest claims.
3. Formal Legal Requirements for Foreign SaaS Creditors
When a foreign entity files legal proceedings in Türkiye, it must comply with specific procedural requirements.
Power of Attorney (Vekâletname)
Foreign SaaS corporations must authorize local legal counsel via a formal Power of Attorney.
- Corporate Execution: Executed by authorized corporate representatives of the foreign entity.
- Legalization: The POA must be notarized in the home jurisdiction and authenticated with an Apostille (under the 1961 Hague Convention) or consular legalization.
- Translation: The apostilled POA must be translated into Turkish by a sworn translator and certified by a Turkish notary.
Security for Costs (Teminat Gösterilmesi)
Under Article 48 of the Turkish International Private and Procedural Law (Law No. 5718 – “IPPL”), foreign entities initiating lawsuits or enforcement actions in Turkish courts are generally required to deposit a security deposit (teminat) to cover potential court fees and damages of the opposing party.
- Bilateral Treaties and Reciprocity: The security requirement is waived if there is an applicable bilateral judicial assistance treaty or international convention (such as the Hague Convention on Civil Procedure) providing mutual exemptions between Türkiye and the vendor’s home jurisdiction.
- Security Amount: If no exemption applies, courts typically set the security deposit at 10% to 20% of the claim value, payable in cash or via a bank guarantee letter issued by a Turkish bank.
4. Judicial Collection Pathways in Türkiye
Foreign SaaS vendors have two primary avenues for recovering unpaid subscription fees in Türkiye: Direct Execution Proceedings or Formal Litigation following Mandatory Commercial Mediation.

+-------------------------------------------------->
5. Fast-Track Execution Without Judgment (İlamsız İcra Takibi)
The most efficient starting point for commercial debt collection in Türkiye is Direct Execution Without a Judgment under Article 42 of the Execution and Bankruptcy Law (Law No. 2004 – “EBL”). This procedure allows a creditor to request debt collection directly through the state Execution Office (İcra Dairesi) without first obtaining a court judgment.
Procedural Flow
- Filing: The foreign SaaS company files an execution request (takip talebi) with the competent Execution Office, attaching the MSA, order forms, and unpaid subscription invoices.
- Issuance of Payment Order: The Execution Office issues an Order for Payment (Ödeme Emri) to the Turkish customer.
- The 7-Day Window: The Turkish debtor has 7 calendar days from the date of service to either:
- Pay the Debt: Full payment of principal, interest, and administrative costs closes the file.
- Remain Silent: If the debtor fails to object or pay within 7 days, the payment order becomes final (kesinleşir). The creditor can immediately request the seizure (haciz) of the debtor’s bank accounts, commercial vehicles, real estate, and third-party receivables.
- Object to the Debt: The debtor may submit a simple written statement to the Execution Office objecting to the debt or signature.
Effect of an Objection
A simple, unreasoned statement from the debtor such as “I do not owe this subscription fee” automatically suspends the execution proceeding. The creditor cannot proceed with asset attachment until the objection is formally lifted or annulled by a competent court.
6. Overcoming Debtors’ Objections: Commercial Mediation and Litigation
When a Turkish customer objects to an execution proceeding, the foreign SaaS vendor must move to judicial litigation to annul the objection.
Mandatory Pre-Litigation Commercial Mediation (Dava Şartı Arabuluculuk)
Pursuant to Article 5/A of the Turkish Commercial Code (Law No. 6102 – “TCC”), commercial mediation is a mandatory prerequisite prior to filing a debt collection lawsuit in commercial courts.
- Application: Filed through the local courthouse Mediation Bureau (Arabuluculuk Bürosu).
- Duration: The mediator must conclude sessions within 3 to 4 weeks.
- Settlement Protocols: If the parties reach a settlement, the signed mediation protocol carries the legal effect of a final court judgment (ilam niteliğinde belge), allowing direct enforcement if the debtor defaults again.
- Non-Participation: If the debtor refuses to participate in mediation sessions without a valid justification, the court will hold the debtor liable for all court litigation costs, even if they ultimately win the lawsuit.
Action for the Annulment of Objection (İtirazın İptali Davası)
If mediation fails to yield a settlement, the foreign SaaS company must file an Action for Annulment of Objection under EBL Article 67 in the Commercial Court of First Instance (Asliye Ticaret Mahkemesi).
- Statute of Limitations: Must be initiated within 1 year from the date the debtor’s objection is served on the creditor.
- Burden of Proof: The SaaS vendor must prove the existence of the contractual agreement, continuous service availability (server uptime logs, user activity records), and proper invoice transmission.
- Execution Denial Penalty (İcra İnkâr Tazminatı): A key incentive under Turkish collection law—if the court determines that the debtor’s objection was groundless, the judge will annul the objection and automatically order the debtor to pay an additional penalty of not less than 20% of the principal claim to the creditor.
7. Precautionary Attachment (İhtiyati Haciz): Securing Assets Early
To prevent a defaulting customer from shifting funds, liquidating assets, or transferring bank balances during litigation, foreign SaaS creditors can seek a Precautionary Attachment order under EBL Articles 257–268.
Requirements for Precautionary Attachment
- Due Debt: The monetary debt must be past due (müaccel).
- Unsecured Claim: The subscription debt must not be secured by a mortgage or pledge.
- Prima Facie Documentary Proof: The creditor must present clear documentary evidence showing the validity of the contract, delivery of service, and unpaid balances.
Mechanics and Execution
- Court Discretion & Guarantee: Courts often order the foreign creditor to deposit a security guarantee (typically 15% to 20% of the claim).
- Fast-Track Execution: Once granted, the attachment order must be presented to the Execution Office within 10 days. Execution officers will serve attachment notices (EBL Article 89) on commercial banks, freezing the debtor’s bank accounts up to the debt amount.
- Strict Timeline: The foreign vendor must initiate main execution proceedings or file the annulment lawsuit within 7 days of enforcing the attachment; otherwise, the freezing order lapses automatically.
8. Evidentiary Aspects Unique to SaaS Debt Collection
Digital SaaS disputes hinge on digital records, software logs, and commercial bookkeeping rules under the CPC and the TCC.
Proof of Service Delivery and Uptime
When a Turkish client claims “non-performance” or “defective software” to justify non-payment, the burden falls on the SaaS vendor to prove performance:
- System Logs & Telemetry: Maintain audit trails showing active user logins, API queries, feature utilization, and administrative account usage.
- Service Level Agreement (SLA) Compliance: Provide historical status page reports and server uptime statistics demonstrating that the cloud infrastructure met contractual availability thresholds.
The 8-Day Invoice Objection Rule
Under Article 21/2 of the TCC, if a commercial entity receives an invoice and does not object to its contents within 8 days of receipt, the contents and unit fees of the invoice are legally presumed to have been accepted.
- Electronic Delivery: Invoices sent via registered electronic mail (KEP), secure customer portals, or tracked email delivery systems help establish the exact delivery date for counting the 8-day period.
Inspection of Commercial Books (Ticari Defterler)
Under CPC Article 222, Turkish courts frequently appoint financial and IT experts (bilirkişi) to examine the commercial records of the parties.
- If the Turkish subscriber recorded the SaaS vendor’s invoices in its official ledger or VAT returns (Form Ba declarations) without objecting, this entry serves as a binding admission of debt under Turkish evidence law.
9. Tax, Currency, and Cross-Border Payment Considerations
Foreign Currency Claims and Interest Rates
SaaS subscriptions are frequently invoiced in USD, EUR, or GBP.
- Currency Selection: Under TCO Article 99, if a debt is denominated in a foreign currency, the creditor can claim payment in the specified foreign currency or in Turkish Lira (TRY) calculated at the Central Bank selling exchange rate on the actual date of payment (fiili ödeme günü).
- Default Interest: Under Law No. 3095 on Interest, default interest for foreign currency debts is calculated based on the highest commercial deposit interest rate applied by Turkish state banks to 1-year foreign currency accounts.
Digital Services Tax (DST) and Value Added Tax (VAT)
Foreign SaaS companies selling digital services to Turkish clients must consider applicable indirect tax rules:
- VAT Requirement (Reverse Charge): In B2B SaaS transactions, where the subscriber is a VAT-registered corporate entity in Türkiye, VAT is generally accounted for by the local customer under the reverse charge mechanism (2 No’lu KDV Beyannamesi).
- Digital Services Tax (DST): Introduced under Law No. 7194, digital service providers meeting global and local revenue thresholds are subject to DST on Turkish-sourced revenues.
- Withholding Taxes: Contracts should include explicit net-of-tax / tax gross-up clauses ensuring that if the Turkish client is required by local tax authorities to deduct withholding tax at source, the net amount received by the foreign SaaS vendor equals the full subscription fee invoiced.
10. Summary of Recommendations for Foreign SaaS Vendors
