Accounts payable

Payables reflect timing and accounting policy

Under accrual accounting, an expense and liability can be recognized before cash leaves the bank. IRS Publication 334 explains that an accrual method generally reports expenses when incurred, subject to all-events and economic-performance rules for tax purposes.

Cash-basis books treat timing differently. Management reports, financial statements, and tax returns may also serve different purposes. State the basis and obtain qualified accounting guidance before comparing periods or entities.

An unpaid invoice is evidence to review. It becomes a valid payable only after the practice confirms the vendor, entity, goods or services, amount, terms, accounting period, and approval route.

Build an invoice-to-payment chain

A useful payable record includes:

• vendor identity, tax and payment setup, and approved contact
• invoice number, date, due date, amount, currency, and terms
• purchase request, contract, or approved rate
• evidence that goods or services were received
• coding to entity, location, department, and account
• exception, credit, dispute, hold, and owner
• approval history, payment method, release date, and bank reference
• reconciliation and correction history

The IRS transaction-recording page describes journals and ledgers and emphasizes complete, accurate records. Build daily or scheduled capture so invoices never depend on one person's inbox.

Separate setup, approval, and payment

Use role separation appropriate to the practice's size. Vendor creation or bank-detail changes, invoice approval, payment release, and bank reconciliation deserve independent checks wherever feasible.

Verify payment-detail changes through a trusted channel already on file. Review duplicate vendor names, invoice numbers, amounts, and bank accounts. Preserve the original evidence and the person who approved each change.

Small practices may lack enough people for complete separation. Add owner review, payment limits, bank alerts, positive pay where available, and retrospective sampling as compensating controls.

Age obligations by due date and status

An AP aging report groups unpaid obligations by due date or age. Keep current, overdue, disputed, held, and scheduled items separate. An old disputed invoice should remain visible without being presented as an approved payment.

Track early-payment discounts, late fees, service interruption risk, automatic renewals, deposits, credits, and cancellation deadlines. Give payroll, taxes, client safety, clinical supplies, rent, insurance, and critical vendors their appropriate planning priority.

The SBA finance page emphasizes bookkeeping, balance-sheet understanding, and cash-flow planning. AP belongs in all three.

A fictional opening and closing balance

Westfield ABA begins the month with $96,000 in accepted unpaid invoices. During the month, it records $41,000 in vendor payments and no new payable for this simplified example.

Closing AP is $96,000 opening AP + $0 new AP - $41,000 payments = $55,000. This balance measures obligations at month end, while $41,000 measures cash paid during the month.

Westfield also locks 20 invoices due for payment-review during the month. Seventeen are approved or validly held by the internal target, so due-cohort timeliness is 17 of 20, or 85%. The three late reviews remain in the denominator with owners and age.

Connect AP with cash and operations

Forecast payment dates beside expected collections, payroll, taxes, debt service, deposits, and minimum cash. Preserve the difference between an invoice due date and the date management hopes to pay.

Avoid stretching critical vendors without an authorized agreement. Delayed payment can disrupt facilities, clinical materials, technology, insurance, or workforce support. Record negotiated changes in writing.

Useful measures include invoices reviewed by target divided by invoices due for review, payments matched to approved obligations divided by payments sampled, duplicate payments confirmed, overdue approved AP by age, and forecast versus actual cash paid. Keep dollars and invoice counts separate.

Handle credits, disputes, and recurring charges explicitly

Vendor credits should link to the original invoice and remain visible until applied or refunded. A disputed invoice needs the disputed amount, reason, evidence, vendor contact, owner, next action, and review date. Keep the undisputed portion on its normal approval path when the agreement allows.

Create a recurring-charge register for rent, software, insurance, waste, utilities, equipment, and professional services. Record renewal dates, notice windows, expected range, allocation, contract owner, and cancellation status. Compare automatic debits with approved terms before closing the month.

Review vendor statements against the payable ledger to find missing invoices, unapplied credits, duplicates, and payments the vendor has not posted. Reconcile stale checks and rejected electronic payments. Preserve the corrected entry, preparer, reviewer, date, and reason.

Tax forms and vendor classification require their own qualified review. The AP workflow should route those questions without allowing an invoice processor to make tax or employment-status decisions.
