Check fraud and payment scams target Texas small businesses because the defenses are usually thin and the money moves fast. The controls that stop them are inexpensive: bank tools like Positive Pay and ACH debit filters, a written rule for verifying any vendor bank change, and weekly account reconciliation. Bookkeeping services in Texas play a direct role here, because fraud shows up in the bank feed before it shows up anywhere else.
Why paper checks are still the weak point
A check carries everything a criminal needs. Your routing number, account number, signature, and business name sit right on the face of the document. Stolen mail is the common entry point, and altered checks clear the bank because nobody compares the cleared image against what was actually written.
Checks don’t have to go away. Plenty of vendors and subcontractors in Central Texas still want them. Three habits close most of the gap: stop mailing checks from an unsecured box, review cleared check images during reconciliation, and turn on Positive Pay so your bank rejects anything that doesn’t match the checks you issued.
The vendor email scam that empties business accounts
A vendor emails to say their banking details have changed and asks that the next payment go to a new account. The email address looks right. The invoice looks right. The payment goes out, and the real vendor calls three weeks later asking about a past due balance.
This scam works on construction companies, property management firms, and medical practices because those businesses pay a long list of vendors and subcontractors on a schedule. Set one rule and hold to it. No banking change gets processed without a phone call to a number already on file, never the number printed in the email. Write down who called, who confirmed, and when.
Four bank controls that stop most fraud before the money leaves
| Control | What it does | Who needs it |
|---|---|---|
| Positive Pay | Matches every check presented to the list you issued and holds anything that doesn’t match | Any business still writing checks |
| ACH debit block or filter | Blocks unauthorized ACH debits and allows only approved originators | Every operating account |
| Dual authorization | One person prepares a wire or ACH batch, a second person releases it | Any business moving money electronically |
| Daily balance and transaction alerts | Flags activity over a set threshold within hours | Owners who look at the bank weekly or less |
Most Texas banks and credit unions offer all four. Some charge a monthly fee for Positive Pay, which tends to cost less than one altered check.
How bookkeeping services in Texas catch fraud inside the reporting window
Business bank accounts don’t carry the same protections that personal accounts do. Your deposit agreement sets the deadline for reporting an unauthorized check or ACH debit, and those windows can be short. Miss the deadline and the loss usually stays with your business.
Weekly reconciliation is what makes those deadlines reachable. A bookkeeper working your accounts every week spots a duplicate vendor payment, an ACH debit from a company you’ve never done business with, or a check number out of sequence while there’s still time to file a claim. Quarterly cleanup finds the same items after the window has closed.
What fraud prevention looks like in day-to-day bookkeeping
Productive Right Now is a bookkeeping and accounting firm in Georgetown, Texas, serving small businesses across Central Texas. Fraud controls aren’t a separate service. They’re built into routine bookkeeping work: reconciling weekly instead of monthly, matching cleared check images to issued checks, keeping the vendor master file current, flagging first-time payees for review, and separating the person who enters bills from the person who releases payment. Those same habits keep your books ready for your CPA at year end.
Frequently asked questions
Does my business bank account have the same fraud protection as my personal account?
No. Consumer protections for unauthorized electronic transfers generally do not extend to business accounts. Your deposit agreement sets the reporting deadline and the liability split between your business and the bank. Read it, write down the window, and reconcile often enough to meet it.
How often should a small business reconcile its bank accounts?
Weekly, for any business writing checks or paying vendors electronically. Weekly reconciliation catches unauthorized debits and altered checks inside most bank reporting windows. Monthly works for very low volume accounts with few payees. Quarterly is too slow to act on what you find.
Is Positive Pay worth the monthly fee for a small business?
Usually, if you still issue checks. Positive Pay compares every check presented for payment against the list you gave the bank and holds anything that doesn’t match on payee, amount, or check number. One prevented altered check often covers a year of fees.
