Tech Consulting Payment Disputes Обзор

Tech consultants and software developers face unique payment challenges. Clients may dispute deliverables, требование scope changes, or simply refuse to pay. California law provides strong protections for creditors, including 10% prejudgment interest on contract debts and адвокатs' fees provisions that shift the cost of collection to the debtor.

Key Advantage for Tech Consultants California гражданский кодекс Section 3289 allows 10% annual interest on unpaid contract debts from the date payment was due - significantly higher than most states.

Common tech consulting payment disputes include:

  • Milestone payment delays - Client claims deliverables don't meet specifications
  • Hourly rate disputes - Client challenges hours worked or rates charged
  • Retainer exhaustion - Work performed beyond retainer without client approval
  • Change order disputes - Client refuses to pay for scope changes
  • Final payment holdback - Client withholds final payment pending "fixes"

Types of Tech Consulting Payment Disputes

Milestone Non-Payment

Client received deliverables but refuses to release milestone payment, often citing minor issues or "incomplete" work that doesn't match original scope.

Disputed Hourly Charges

Time-and-materials contracts where client challenges hours logged, claims inefficiency, or disputes the billing rate applied.

Retainer Exhaustion

Initial retainer depleted but work continues at client's request. Client refuses to pay additional invoices beyond original retainer.

Change Order Disputes

Additional work requested during project but client claims it was part of original scope or refuses to pay change order rates.

Final Payment Holdback

Client withholds 10-20% final payment indefinitely, demanding endless revisions or "fixes" not in original contract.

Startup Equity Substitution

Client attempts to substitute equity or future revenue share instead of cash payment as originally agreed.

Software-Specific Payment Issues

Software consulting has unique payment challenges:

  • Bug vs. Feature disputes - Client claims bugs are preventing acceptance when they're actually requesting new features
  • Integration failures - Third-party API or system changes cause issues; client blames consultant
  • Performance benchmarks - Vague performance requirements lead to disputes over what constitutes "completion"
  • Security audit failures - Post-delivery security findings used to withhold payment
  • User acceptance testing (UAT) delays - Client delays testing indefinitely to avoid payment trigger

California Law on Contract Payment Disputes

гражданский кодекс Section 3287(a) - Prejudgment Interest

A person who имеет право на recover убытки certain, or capable of being made certain by calculation, may also recover interest from the date the right to убытки vests.

гражданский кодекс Section 3289(b) - 10% Interest Rate

If a contract does not stipulate a legal rate of interest, the rate is 10% per annum on contract debts after breach. This applies to unpaid consulting invoices from the date payment was due.

Key Legal Principles

Written Contract Срок Исковой Давности

California Code of Civil Procedure Section 337 provides a 4-year срок исковой давности for written contract claims. For oral contracts, CCP 339 allows only 2 года. This is why written consulting agreements are critical.

Адвокатs' Fees Provisions

California гражданский кодекс Section 1717 makes адвокатs' fees provisions reciprocal - if your contract allows the prevailing party to recover адвокатs' fees, this applies regardless of which party initiates судебный процесс. This incentivizes clients to pay rather than litigate.

Practice Tip Always include an адвокатs' fees provision in your consulting agreement. Under CCP 1717, even a one-sided provision becomes mutual, but an express mutual provision is clearer and more enforceable.

Account Stated Doctrine

Under California law, when a client receives an invoice and doesn't object within a reasonable time (typically 30 days), it becomes an "account stated" - essentially an admission of the debt. This doctrine strengthens your position significantly.

Legal Element Requirement Benefit
Written Contract Signed agreement with payment terms 4-year SOL, clear terms for enforcement
Invoices Sent Detailed invoices with due dates Establishes debt certainty for interest
Нет Timely Objection Client didn't dispute в течение 30 дней Account stated - admits the debt
Требование Written demand with deadline Triggers interest, shows добросовестность
Адвокатs' Fees Clause Contract provision for fees Recoverable legal costs if you sue

Common Client Defenses & Responses

Anticipate these defenses and prepare your responses.

"The deliverables don't meet specifications"

Your response: Request specific, written identification of which specification was not met. Reference the acceptance criteria in the SOW. If they accepted prior milestones without objection, that establishes the standard. Point out any "bug vs. feature" confusion.

"We never approved those hours"

Your response: Show email approvals, meeting notes, or project management records authorizing the work. Reference any "time and materials" provisions that don't require pre-approval. Demonstrate the work was requested and beneficial.

"The work was already included in the original scope"

Your response: Compare the original SOW line-by-line with the additional work performed. Show the change request communications. If they verbally approved changes without a formal CO, that's still binding under California law.

"We're disputing the quality"

Your response: Quality disputes don't excuse payment for work performed. They may have a separate требование, but can't unilaterally withhold payment. Offer to cure specific, documented defects while demanding payment for completed work.

"Our company is having cash flow problems"

Your response: Cash flow doesn't excuse contractual obligations. Offer a payment plan with interest, but get it in writing with personal guarantees if the company is distressed. Consider UCC filing or other security.

"We're unhappy with the project manager/consultant"

Your response: Dissatisfaction with personnel doesn't excuse payment for work performed. Address any legitimate performance concerns separately from the payment obligation.

Часто Задаваемые Вопросы

Да. Under California law, non-payment is a material breach that excuses further performance. Однако, review your contract for any "pay when paid" or continuation provisions. Best practice: Отправить письменное уведомление that work will cease if payment isn't received by a specific date, then follow through. Document everything.

You can still recover under oral contract or quantum meruit (reasonable value of services). Однако, the срок исковой давности is only 2 года (vs. 4 for written contracts), and proving terms is harder. Gather all emails, texts, and documents that доказательства the agreement. Interest may be limited to 7% instead of 10%.

Small claims is efficient for claims up to $12,500 (individuals) or $6,250 (businesses). Нет адвокатs allowed, which can be an advantage. Однако, for larger tech consulting disputes, you'll need superior суд or арбитраж. Consider whether your contract requires арбитраж.

Under гражданский кодекс 3289(b), interest accrues at 10% per annum on contract debts from the date payment was due. Calculate: (Principal × 0.10 × Days Past Due) ÷ 365. For a $50,000 invoice 180 days past due: $50,000 × 0.10 × 180 ÷ 365 = $2,466 interest. This continues until paid.

Да, if your contract has an адвокатs' fees provision. Under гражданский кодекс 1717, even a one-sided provision (only benefiting one party) becomes mutual. Without a contract provision, California generally follows the "American Rule" where each side pays their own fees, with limited exceptions.

File a proof of требование immediately when you receive bankruptcy notice. Your требование is likely "unsecured" unless you have a security interest. Consider whether any payments in the 90 days before filing might be preferential (recoverable by the trustee). Consult a bankruptcy адвокат for significant amounts.

This depends on your contract. If it says ownership transfers upon delivery (regardless of payment), withholding may be breach. If ownership transfers upon payment, you have more leverage. Review IP provisions carefully. Also consider whether you have a подрядчик's lien right under гражданский кодекс 3110+.

For written contracts: 4 года from breach (CCP 337). For oral contracts: 2 года (CCP 339). The clock typically starts when payment was due. Partial payments or written acknowledgments can restart the clock. Don't wait - file suit before the deadline approaches.
