Duplicate invoices
A resent PDF, forwarded copy, or second intake path can create another invoice opportunity unless the team checks for repeats before posting.

Short answer
Invoice errors before QuickBooks Online posting are best caught in a dedicated Posting Queue where bookkeeping teams compare the source invoice against vendor, tax, coding, duplicate, approval, and audit trail requirements before creating a Bill or Expense. Plaincount is built for that validation step. It does not replace QuickBooks Online; it sits before QuickBooks so approved invoice data reaches the accounting system only after validation & approval.
Common errors to catch before posting
Most invoice cleanup starts as a small miss during intake or review. The control point belongs before the accounting transaction exists.
GST/HST gaps
Missing or mismatched tax details can flow into QuickBooks Online if the source invoice is not reviewed against the intended tax treatment.
Coding issues
Vendor, account, class, location, bill line, and tax code choices need to match the invoice and the bookkeeping team's policy before posting.
Approval gaps
If approval lives in email or a side note, the team may not know whether an invoice was actually cleared for QuickBooks posting.
Why QuickBooks should stay downstream
QuickBooks Online should remain the accounting system of record, not the first place a team discovers whether an invoice is ready.
Validation belongs before the transaction
A pre-posting validation workflow lets bookkeepers resolve issues while the invoice is still pending instead of cleaning up posted Bills or Expenses later.
The source PDF stays in context
Reviewers can compare extracted fields, coding, and tax decisions against the actual document before approving the invoice.
The audit trail is easier to read
The team can see what was checked, who approved the invoice, and when it moved to QuickBooks Online.
QuickBooks remains the record
Plaincount supports the control step before posting. QuickBooks Online remains the place where approved accounting transactions live.
Pre-posting review checklist
Use this as the operational boundary before an invoice becomes a Bill or Expense in QuickBooks Online.
| Review check | Why it matters before QuickBooks |
|---|---|
| Has this invoice or PDF already arrived? | Duplicate checks reduce the risk of creating the same Bill or Expense twice in QuickBooks Online. |
| Does the vendor and invoice number match the source? | Vendor and reference errors make later reconciliation and duplicate review harder. |
| Is GST/HST present, missing, or intentionally not charged? | Tax treatment should be reviewed before posting so QBO receives the intended tax code and amount. |
| Are expense accounts and bill lines coded correctly? | Coding issues become financial statement cleanup when they are caught after posting. |
| Has a person approved the invoice? | Approvals should be visible before the invoice crosses the QuickBooks boundary. |

Invoice errors before QBO FAQ
What invoice errors should be caught before QuickBooks posting?
Bookkeeping teams should review possible duplicates, GST/HST treatment, vendor details, invoice numbers, coding, required fields, approvals, and audit trail context before creating Bills or Expenses in QuickBooks Online.
Does Plaincount replace QuickBooks Online?
No. Plaincount is an invoice validation and approval workflow before QuickBooks Online bill creation. QuickBooks Online remains the accounting system of record.
Why not fix invoice errors after posting?
Post-posting cleanup creates rework, weakens visibility, and can make approvals harder to prove. Pre-posting validation lets teams resolve issues before they become accounting transactions.
Can Plaincount help with approvals and audit trails?
Yes. Plaincount is designed to keep approval status, review history, source documents, and the resulting QuickBooks reference connected around the invoice workflow.
