Stackpack - 2026 Pricing, Features, Reviews & Alternatives

Stackpack is vendor management, contract management, and AI spend management software for finance and operations teams. Instead of chasing vendor data across spreadsheets, inboxes, and accounting software, Stackpack connects to your existing financial stack and gives you one always-current view of every vendor, contract, and dollar (and token) your company spends. Most teams are fully live within a day, no IT lift required, ROI in weeks rather than months.

Vendor Management: Stackpack connects to your accounting software (QuickBooks Online, NetSuite, Sage Intacct, Rillet, Campfire) and pulls in every vendor across software, services, and contractor spend. Each record includes category, department, owner, and last-twelve-months spend, plus AI benchmarks and renewal recommendations built from real-world spend data, so you're never negotiating blind.

Contract Management: Upload contracts by email, bulk upload, or Google Drive, and Stackpack's finance-trained AI extracts key terms, pricing, seat counts, and renewal dates, then matches each contract to the right vendor. No more digging through a contract to find what you signed.

Renewals Manager: A dedicated renewals command center shows every upcoming renewal by month, with time-based filters and clear ownership. Stackpack alerts you before contracts auto-renew and pairs each one with an AI Renewal Guide, complete with pricing benchmarks and negotiation tips. Customers average a 21% spend reduction after their first renewal cycle.

Spend Management (Spend Intelligence and Utilization): Get real-time spend visibility by department and owner, spot cost spikes before they hit budget, and uncover waste before it snowballs. Utilization tracking monitors seat and license usage so teams stop paying for empty seats.

AI Spend Management (Token Attribution): Finance teams get monthly AI invoices with no idea who drove the spend. Stackpack maps every API call back to the employee, model, and team behind it, across OpenAI, Anthropic, and Cursor, in real time, with budgets and alerts before anyone blows through their cap.

AI Assistant: Ask Stackpack's finance-tuned AI Assistant any question about vendors, contracts, or spend and get a plain-English answer in seconds. Unlimited prompts, full history, every plan.

Requests and Approvals: Customizable intake workflows route new vendor requests to the right approver, by department, amount, and type, with auto-nudges and a full audit trail. Department heads move fast; finance, IT, and legal stay in the loop.

Integrations and security: Stackpack connects to QuickBooks Online, NetSuite, Sage Intacct, Rillet, Campfire, Digits, Slack, and Google Workspace, and supports SSO via Google and Microsoft, custom permissions, bulk CSV uploads, and SOC 2 compliance.

Pricing: Stackpack charges based on vendors managed, not a percentage of spend, so the incentive is to save you money, not take a cut. Basic starts at $350/month plus $100 per 100 vendors, covering the AI Assistant, Vendor and Spend Management, and Contract and Renewal management. Standard, from $1,250/month, adds utilization tracking, AI token monitoring, and approvals. Enterprise adds custom workflows and a CSM. Every plan: 30-day free trial.

Stackpack is trusted with billions in vendor and AI spend across thousands of vendors at companies like ZeroEyes, dub, Smallstep, and Fexa. ZeroEyes' CFO says Stackpack gave his team "complete visibility into every vendor relationship across our entire organization." Smallstep gained visibility into $3M in spend across 7 departments and 175 vendors, and Fexa saved $78,000 through Stackpack-assisted renewals. The team has built at Affirm, Asana, PayPal, Google, and Twilio, backed by investors who also backed Carta, Airtable, and Intercom.

Unlike spreadsheets or legacy vendor management tools, Stackpack gives finance teams one connected system: see everything, run lean, stay in control. Try it free for 30 days or schedule a demo at stackpack.ai.
