How does an attorney demand letter help collect a B2B invoice?
S
Three ways. First, it puts the debtor's counsel on notice that the matter is now legal, not just A/R, which moves it up the priority list. Second, it cites the controlling California doctrines (account stated, § 1717 fee shifting, § 3287 prejudgment interest) and quantifies the total exposure including interest and fees. Third, it serves as the demand that triggers § 3287 interest accrual on a date the debtor cannot dispute. Most B2B accounts pay within two to four weeks of an attorney letter, and the cost of the letter is dwarfed by the interest and fee leverage the letter creates.

What is the account-stated doctrine?
S
An account stated is established when a creditor sends invoices, the debtor receives them without objection within a reasonable time, and the debtor's conduct manifests assent (partial payment, written acknowledgment, silent retention of invoices). Under California law (Maggio Inc. v. Neal, 196 Cal.App.3d 745 (1987)), an account stated is a separate cause of action from the underlying contract and shifts the burden to the debtor to disprove the balance. A clean account-stated record (dated invoices, delivery proof, no timely written objection) often makes the case decisively easier than litigating breach-of-contract elements.

What is the open-book-account theory?
S
An open book account is a running record of transactions, debits, and credits maintained in a regular course of business. CCP § 337a defines it formally. The theory is useful when the parties had a continuing commercial relationship (multiple invoices over months or years), there is no single integrated contract, and the creditor's books show the running balance. It runs parallel to account stated and breach of contract and is usually pleaded alongside both as alternative theories.

How much prejudgment interest is available under § 3287?
S
California Civil Code § 3287 entitles the prevailing creditor to interest from the day the principal amount became liquidated and certain. The statutory default rate is 10% per annum (Cal. Const. art. XV, § 1; Civ. Code § 3289(b) when no contract rate applies). On a $50,000 unpaid invoice held for 12 months, that is $5,000 in interest added to the demand. The interest runs through the date of judgment and post-judgment interest takes over under CCP § 685.040 at 10% as well.

How does § 1717 attorney-fee reciprocity work?
S
Civ. Code § 1717 makes attorney-fee clauses in contracts reciprocal. If the contract gives the creditor a right to fees on default, the prevailing party in any action on the contract recovers fees, regardless of which side the clause originally favored. This makes one-sided fee clauses in B2B contracts (which are common in service agreements drafted by the creditor) work as much for the creditor as for the debtor. The demand letter cites § 1717 to make the fee exposure concrete, especially when the contract contains a fee clause.
You
What is the statute of limitations on California B2B collections?
S
Four years for written contracts (CCP § 337), two years for oral contracts (CCP § 339), and four years for an open book account from the date of the last item in the account (CCP § 337a). Account stated runs four years from the date the account was stated. The point of the demand letter is to lock in a payment plan or admission of liability before the older invoices fall out of the limitations window.
You
Do you handle international B2B collections?
S
Yes, with a venue caveat. If the debtor is outside the United States and the contract does not specify California venue and law, enforcing a California judgment internationally is a separate project that requires local counsel in the debtor's jurisdiction. For most cross-border B2B disputes, the attorney letter still works because international debtors usually want to avoid US-court entanglement and reputation harm. I draft the letter with reference to whatever choice-of-law clause exists and flag the enforcement realities so the client can budget accordingly.
You
What if the debtor disputes the work?
S
A late-asserted dispute is often where account stated wins. If the debtor accepted invoices for months without objection and only raised quality concerns after non-payment, the silence is the assent. California courts look skeptically at post-hoc disputes when the contemporaneous record shows acceptance. The demand letter addresses any dispute head-on, attaches the contemporaneous communications, and explains why the dispute does not negate the obligation. Genuine quality disputes get carved out and reduced separately.
You
Can you file the lawsuit if the debtor still doesn't pay?
S
The $1,200 package includes a court-ready California Superior Court complaint with account-stated, open-book-account, and breach-of-contract counts ready for filing. I do not personally appear in court for collections; the package is structured so the client (or their preferred litigation counsel) can take the filing forward without redoing the legal work. For collections work where appearance is needed, I refer to litigators who handle B2B collections on flat-fee or hybrid arrangements.
You
How long does the demand-letter process usually take?
S
Two to four weeks for most accounts. Debtor response usually arrives within ten to fifteen business days of certified-mail receipt. If the response is a payment, the matter closes. If the response is a counter-offer or document request, I handle the negotiation rounds. If the response is silence past 30 days, the next step is the draft complaint and the filing decision. The interest meter keeps running under § 3287 throughout, which makes delay expensive for the debtor.
