HOW IT WORKS

Accounts receivable automation that turns
every purchase order into a billed invoice.

When a PO arrives in any format, PDF, email, scan, or upload, Dost's AI captures buyer details, line items, taxes, and the PO number in seconds. It auto-maps the customer, price lists, discounts, and cost centres against your accounts receivable records, so exceptions drop and data stays clean from the start.

FAQS

Everything you need to know
about purchase order to invoice conversion.

What is a PO number?

A PO number (purchase order number) is the unique reference your customer assigns to a purchase order when they request goods or services from you. It identifies the order across both parties and travels with every related document — purchase order, delivery note, invoice — so the same transaction can be tracked end-to-end without ambiguity. On the AR side, the PO number is the link that ties an invoice back to the original purchase order.

What is purchase order numbering?

Purchase order numbering is the system a company uses to assign a unique PO number to every purchase order it issues. It typically follows a structured format (year, department code, sequential number, etc.) so each PO is traceable, auditable, and easy to reconcile against invoices. A clean purchase order numbering scheme is the foundation of accurate accounts receivable workflows — without it, matching invoices to POs at scale becomes impossible.

What's the difference between a purchase order and an invoice?

A purchase order is the document a buyer issues to request goods or services from a supplier at agreed terms; an invoice is the document the supplier issues to request payment after delivery. The purchase order comes first (sets the contract), the invoice comes second (closes the financial side). Both reference the same PO number, which is how systems like Dost link them automatically for matching, reconciliation, and reporting.

What types of documents can Dost receive to generate invoices?

Dost receives purchase orders in virtually any format — PDF, email attachment, scanned image, or direct upload. You can also connect Google Drive, Dropbox, or your accounting inbox for fully automated PO collection. Once received, Dost's AI extracts every field and converts the PO into a sales invoice or delivery note ready for sending.

How does PO-to-invoice automation work?

PO to invoice automation is a five-step flow that converts a received purchase order into a finished sales invoice without manual input. (1) The PO arrives in any format. (2) AI extracts buyer details, line items, taxes, and the PO number. (3) The data is matched against your AR customer profile. (4) A branded invoice is auto-generated with correct VAT, currency, and numbering. (5) The invoice is linked back to the source PO and sent via email, ERP, or client portal. The whole cycle takes seconds per document instead of minutes.

Can I customise the format of my invoices or delivery notes?

Yes. You can fully customise invoice and delivery note templates to include your company logo, payment terms, numbering format, and client-specific fields. Dost adapts to your branding and billing needs across every customer segment.

Can I attach documents to every invoice?

Yes. You can attach signed delivery notes, contracts, emails, or supporting images to every invoice as proof. Everything stays linked and traceable within the same workflow, making audits, dispute resolution, and client enquiries faster to handle.
