The Invoice Collection Report in Perk helps financial reviewers verify that supplier invoice amounts match what Perk billed to your account. When the report flags a discrepancy, it means the data from the supplier invoice and the billing statement don't line up exactly. This article explains what discrepancies are, why they happen, and what (if anything) you need to do about them.
Understanding discrepancies in hotel invoicing
Hotel invoicing is rarely a straight line from booking to invoice. Between the moment Perk charges your account and the moment a supplier's invoice arrives, several things can happen: the hotel may apply local fees, use a different exchange rate, split charges across multiple VAT rates, or simply take a few days to generate the invoice at all. Because Perk's Invoice Collection Report pulls together billing statement data and supplier invoice data into a single view, any difference between those two sources shows up as a discrepancy. This doesn't mean something is wrong with your account — it means the report is doing its job, surfacing the gap so you can decide whether it needs attention.
Tracking discrepancies in the report
The Invoice Collection Report includes two tables. The Billing Statements table shows each billing statement entry alongside the invoices it maps to, including the collection status and any discrepancy flags. The Supplier Invoices table breaks supplier invoices down by VAT rate — so a single hotel invoice covering room charges and breakfast can appear as multiple rows, each with its own rate, net amount, and gross amount. This structure means that when you investigate a discrepancy, you'll often find the detail you need in the Supplier Invoices table, not just the headline status in the Billing Statements table.
Discrepancy types
The table below covers every discrepancy type you may see in the report, what it means, and what to do.
| Discrepancy type | What it means | Common cause | What to do |
|---|---|---|---|
| Not yet collected | Perk expects an invoice but hasn't received it yet. | The stay was recent, the hotel is still processing, or the invoice hasn't been issued yet. | Wait — this often resolves in the next daily refresh. No action needed unless it persists. |
| Unable to collect | Perk tried to retrieve the invoice but couldn't. | The hotel didn't issue an invoice, the billing address was incorrect, or the supplier doesn't invoice for this booking type. | Contact support if you need the invoice for VAT reclaim or audit purposes. |
| Amount mismatch | The supplier invoice total doesn't match what Perk billed. | The hotel charged a different rate than booked, added local taxes or fees, or applied a post-stay correction. | Review the line items in the Supplier Invoices table. Contact support if the difference is unexpected. |
| VAT discrepancy | The VAT amount or rate on the invoice doesn't match the expected breakdown. | The supplier applied a different VAT rate, or split line items differently (for example, room charges and breakfast at separate rates). | Review the VAT rate and expense category in the Supplier Invoices table. This is common for stays that include multiple service types. |
| Currency difference | The invoice is in a different currency than the billing statement. | The hotel invoiced in its local currency while Perk billed in your account currency, with an FX conversion applied between them. | Check the exchange rate applied. Differences are expected in multi-currency accounts — escalate only if the converted amount looks significantly off. |
| Credit note / correction | The original invoice was amended or cancelled. | A rebooking, a dispute resolution, or a hotel-side correction. A credit note reduces or reverses the original invoice amount. | Check whether the credit note matches a cancellation or change you made. If it's unexpected, contact support. |
Determining discrepancies that require action
The majority of discrepancy statuses in the Invoice Collection Report are informational — they explain a gap rather than signal an error. A Not yet collected status, for example, is a normal part of hotel invoicing for recent stays. A VAT discrepancy is common when a hotel bundles room and breakfast charges on a single invoice at different rates. The cases that typically need follow-up are:
- Unable to collect (if you need the invoice for compliance or VAT reclaim)
- Credit note/correction (if you weren't expecting a reversal)
