How do I match an invoice to its purchase order?

Record the PO number on each invoice as you file it, and keep PO copies in the same folder, so the invoice and its order can be checked side by side.

Does Cash Workspace read the PO and amount off the invoice for me?

No — it does not scan or extract data from invoices. You enter the details once and attach the PDF, and the record keeps them together for fast retrieval.

How do I find one supplier's invoices quickly?

Group invoices in a folder per supplier rather than by date. Opening that supplier's folder shows every invoice you've filed for them.

Organize incoming supplier invoices as records

A product business runs on a steady flow of supplier invoices — and each one carries a PO number, a due-date expectation, and a PDF that has to be matched to what was ordered. When those invoices land in email and stay there, matching them to purchase orders and answering "is this paid?" turns into a manual hunt. Cash Workspace lets you file each incoming invoice as an expense record, tagged with its PO and vendor, grouped by supplier so retrieval is instant.

The problem

Why incoming supplier invoices pile up

Invoices arrive faster than they get filed, and without a PO reference on each record, matching them to orders becomes guesswork.

An invoice arrives but you can't tell which purchase order it belongs to.
Two suppliers send invoices with the same number and they get confused.
You're not sure whether an invoice was already paid because the record and PDF live apart.
A due date passes unnoticed because nothing flags when payment is expected.
Finding last quarter's invoices from one supplier means scrolling the whole inbox.

The workflow

File each supplier invoice the same way

Turn every incoming invoice into a record with a PO note and group it by supplier as it arrives.

1
Create a folder per supplier
Group invoices by the supplier who sent them so retrieval is grouped, not chronological.
2
Record each invoice on arrival
When an invoice lands, create a record with vendor, invoice number, amount, and the PO number it matches.
3
Note the due date
Add the payment due date as a note so you can scan for what's coming up.
4
Attach the invoice PDF
Save the supplier's PDF to its record so the document and its details stay together.
5
Mark it once paid
Add a paid note when payment goes out so the record reflects current status.

Record structure

What to record for each supplier invoice

These fields let you match invoices to orders and find them by supplier.

Supplier: The vendor name, kept consistent so the supplier folder stays whole.
Invoice number: The supplier's reference, used to query a specific invoice.
PO number: The purchase order this invoice matches, so order and invoice line up.
Amount: The invoiced total, matching the attached PDF.
Due-date note: When payment is expected, so you can scan for upcoming dates.
Status note: Received, approved, or paid, so the record reflects where it stands.
Invoice PDF: The supplier's document attached to the record.

Example setup

An example supplier-invoice folder

One way to group invoices so any one is quick to retrieve.

Supplier — open invoices

Received and approved invoices not yet paid, each with PO number and due-date note.

Supplier — paid invoices

Invoices marked paid, kept for the supplier's full history.

Purchase orders

Copies of POs so each invoice can be checked against its order.

Common mistakes

Mistakes to avoid

Recording the amount but not the PO number, so invoices can't be matched to orders.
Leaving invoices in email instead of filing them under the supplier.
Letting two suppliers' identical invoice numbers collide without a vendor tag.
Forgetting to mark an invoice paid, so its status stays ambiguous.
