Your SaaS customer just filed for bankruptcy. What happens to your unpaid invoice?

A customer files Chapter 7 or Chapter 11. Your $50,000 annual subscription invoice is 90 days past due. You do not lose the right to collect—but the rules change completely and you have to move immediately to preserve your claim. The bankruptcy filing does not erase the debt. What it does is replace your private collection effort with a structured legal process where you are one unsecured creditor among many. The question is not whether the debtor owes you; it is whether you file the right paperwork at the right time, before the money runs out.

TL;DR: An automatic stay stops all collection activity the moment the debtor files. Your two windows are: file a proof of claim before the bar date (typically 90 days after the filing), and if you were placed with an agency before the petition date, those pre-petition efforts may survive the stay. Recovery after filing is pennies on the dollar as an unsecured creditor—which is why pre-bankruptcy placement at 85%+ success odds is the real play.

The automatic stay is a wall, not a door

The moment the debtor files, an automatic stay under 11 U.S.C. § 362 takes effect. The stay halts all collection activity—letters, calls, emails, demand letters, litigation—against the debtor. Violating it can result in sanctions and actual damages payable to the debtor. Do not send another invoice or call the AP department after you learn of the filing. What you can do is file a proof of claim with the bankruptcy court. That is the single most important action you can take as a creditor. The court sets a bar date—typically 90 days after the petition date for Chapter 7, longer in Chapter 11—and if you miss it, your claim is disallowed and you recover nothing. File the proof of claim even if you think there are no assets. Plans change, assets surface, and the only creditors who share in a recovery are the ones on the official claims register.

Preference risk: the check you already cashed can be clawed back

Here is the part most software vendors do not expect. If the debtor paid you within 90 days of the bankruptcy filing (or within one year for insiders like officers or directors), the trustee can claw that payment back as a preferential transfer. The logic: the debtor paid you while leaving other creditors empty-handed, and the trustee is required to recover that money and distribute it fairly among all creditors. Net-90 payment terms make this a double hit. Your customer paid the invoice at day 75, the trustee files the case at day 120, and that payment falls inside the 90-day preference window. You now owe the money back to the bankruptcy estate—and you still hold the unpaid current invoice as an unsecured claim. This is why collecting from a customer showing signs of distress is urgent: if you wait for them to pay under pressure and they file anyway, the payment can be unwound.

Timing is everything: pre-petition placement vs. post-petition claim

If you placed the account with a collection agency before the debtor filed, those collection efforts happened pre-petition and the fees you paid or agreed to pay are generally not affected by the automatic stay. The court looks at whether the collection activity ended before the petition date, not whether the account was still unresolved. If you placed the account before the filing, the debtor may have already paid under pressure—and if that payment is later challenged as a preference, the agency can help trace the payment trail and produce the documentation needed to defend it. If you placed it after the filing, you wasted the effort: any collection attempt after the petition date violates the stay and exposes you to sanctions. In practice, the window for effective placement closes the moment the debtor files.

What recovery looks like after bankruptcy

As an unsecured creditor in a Chapter 7 liquidation, you stand behind secured creditors, administrative expense claimants, and priority unsecured claims (taxes, wages). In most Chapter 7 cases unsecured creditors recover between 0% and 10% of their claim, often after a year or more of waiting. Chapter 11 reorganizations can return more—sometimes 20% to 50% under a plan of reorganization—but that is still cents on the dollar, paid out over years, and subject to the plan being confirmed and performed. By contrast, recovery odds before a bankruptcy filing, when the debtor is still deciding which creditors to pay, are 85%+ for claims placed under 12 months past due. The numbers tell the story: the highest recovery you can achieve in bankruptcy court is still worse than the worst recovery you can achieve by placing the account before the filing.

Spot the filing before it happens

Bankruptcy rarely surprises everyone. The debtor's behavior changes weeks or months before the petition date. Watch for these signals on any customer that owes you a material balance:

• Requests for extended payment terms out of nowhere—Net-30 to Net-90, or asking to pay in quarterly installments.
• Avoiding phone calls and emails—the AP contact who always responded suddenly goes silent.
• C-suite turnover—a departing CFO, CEO, or controller is often a sign the board is trying to restructure.
• Downsizing announcements—layoffs, office closures, discontinued product lines, or public statements about cost reductions.
• Stretching payments to other vendors—if you hear from mutual contacts that the same customer is late to everyone, the pattern is systemic.

Any single signal can be benign. Two or three together, especially on a customer that already owes you a past-due balance, mean the filing window is open. Place the account before it closes.

The practical play

If the debtor has already filed: file your proof of claim by the bar date, consult a bankruptcy attorney about the likelihood of an unsecured distribution, and do not count on meaningful recovery. Monitor the case docket (PACER) for plan filings and asset notifications. If the debtor has not filed but is showing warning signs: place the account immediately. Pre-bankruptcy placement preserves recovery odds at 85%+ on claims under 12 months, and the same contingency structure—25% on accounts under 12 months, 33% over, 40% on second placements, no recovery, no fee—applies whether the debtor is thriving or struggling.
