AI reads and interprets your invoices and receipts, intelligently matches them to your Spire data, and posts them automatically—no manual entry required.
AI That Understands Your Documents
Using AI APIs, each document is read and interpreted, then intelligently matched to your Spire data.
Vendor Invoices
AI extracts vendor name, invoice number, dates, line items, and totals from PDF or scanned invoices.
Receipts & Expenses
AI reads receipt images, extracts vendor, amount, date, and tax, then categorizes the expense.
Manual AP is Slowing You Down
Your team spends hours every week keying invoices and receipts into Spire. It's tedious, error-prone, and takes focus away from higher-value work.
Invoice Backlog
Vendor invoices pile up waiting to be entered. Late entries mean missed early-pay discounts and frustrated suppliers.
Tedious Data Entry
Someone has to manually type vendor, invoice number, line items, amounts, and GL codes for every single document.
Costly Mistakes
Typos in amounts, wrong vendor codes, duplicate entries. Errors create reconciliation headaches and audit issues.
From Document to Posted in 4 Steps
Envelope AI automates the entire AP workflow so your team can focus on exceptions, not data entry.
Submit Document
Email invoices or receipts to your dedicated inbox, or upload directly.
AI Reads It
Claude AI extracts all relevant data—vendor, amounts, dates, line items, tax.

Complete AP Automation for Spire
Everything you need to eliminate manual invoice and expense entry.
AI-Powered Document Intelligence
Claude AI doesn't just OCR your documents—it understands them. It extracts structured data from messy invoices, matches vendors by name variations, and learns your GL coding patterns over time.
- Reads PDFs, scanned images, photos of paper invoices
- Fuzzy vendor matching—finds "COSTCO WHOLESALE" even if Spire has "Costco"
- Auto-extracts HST/GST for input tax credits
Email Inbox Monitoring
Connect to Office 365 or any IMAP inbox. Envelope AI automatically fetches new documents and queues them for processing—vendors can email invoices directly.
Vendor Invoice Processing
AI matches invoices to your existing Spire vendors, extracts line items, and creates AP entries ready for review and posting.
Expense & Receipt Processing
Corporate card receipts post as GL journal entries. Personal card expenses create AP invoices for employee reimbursement. HST handled automatically.
Category Rules Engine
Define vendor patterns to auto-categorize. "STAPLES*" → Office Supplies. "SHELL*" → Fuel. AI fills in the gaps for everything else.
